HEXUS.net : Review : ECS PF88 Extreme Hybrid Mainboard Page 1 of 24 Product: ECS PF88 Extreme Hybrid Mainboard Author: Tarinder Date Of Review: 12th May 2005 Sample Provider: ECS ELITEGROUP print this review discuss in the forums email to a friend ECS PF88 Extreme Mainboard Enthusiasts are a fickle bunch of people, if you ask me. One minute they're swooning over the creamy, hardto-elucidate quality that Intel brings to the table with its Hyper-Threading-equipped Pentium 4 processors. Next minute, the same enthusiasts are having performance pangs that only AMD's Athlon 64 S939 CPUs can satiate. That's why it's not uncommon for informed users to jump ship every so often, to really see if the grass is greener on the other side. The most fundamental question that a prospective PC purchaser needs to make, then, is which platform to go with. Once chosen, due to chipset and socket differences, you're stuck with a particular platform unless you take the drastic step of changing motherboards, which entails a long afternoon of hardware and software changes. Think about it, no other PC-related component is so much hassle, and changing back is just as much trouble. ATI and NVIDIA's graphics cards all share the same interfaces, so it's a simple matter of uninstalling drivers, popping in another card, and installing new drivers; a 10-minute job at best. Changing system memory is a cinch, and SATA hard drives can now be plugged, on-the-fly, into most modern board's ports. The ideal state of affairs would be the ability to run both Intel and AMD's CPUs on one board, with one operating system. Whilst technically feasible, ATX PCB considerations and the extra cost of paying for a socket that may or may not be used has always stopped the adventurous motherboard makers from having a go. ECS, however, has decided to throw away any pre-conceived mainboard design ideas by launching a single motherboard with the capacity to support most of today's top-end performance platforms, beginning with Intel's LGA775 and AMD's Socket-939. You'll be wondering how it's done. Read on to find out. http://www.hexus.net/content/reviews/review_print.php?dXJsX3Jldmlld19JRD0xMTgx 13/05/2005 HEXUS.net : Review : ECS PF88 Extreme Hybrid Mainboard Page 2 of 24 Take a few seconds to ponder the ECS PF88 Extreme's layout. For all intents and purposes, barring the extralong connector (hint, hint) running through the middle of the board, it's a regular LGA775-supporting board. In fact, with 2 x16 PCI-Express slots you'd be forgiven for thinking it's ECS' take on Intel-based SLI, but, as you may have guessed, the second, orange-coloured PCI-Express x16 slot is reserved for something else. Can you figure it out? I'll discuss the merits of this standalone motherboard before detailing just how it can be transformed into a S939 board. In its basic form, then, the PF88 Extreme is a SiS chipset-powered PCI-Express LGA775 mainboard, with a SiS656 northbridge and SiS965 southbridge, linked together via a 1GB/s interconnect. There's plenty of room around the socket area, and it makes for easy mounting of Intel's fiddly LGA775 reference coolers. What's more, unlike Intel, the SiS656 supports the newest iteration of dual-core Pentium CPUs immediately. LGA775's designed to run with DDR2 memory in mind. The PF88 Extreme carries the usual 4 DIMM slots that offer dual-channel bandwidth by populating same-coloured slots (or all 4, for that matter). Right off the bat, the PF88's SiS656 northbridge, located just to the left of the CPU socket, supports dual-channel DDR2-533 and DDR2-667, bringing it in line with Intel's i9xx models. The northbridge also supports the first orange-coloured PCI-Express x16 slot, just to the left. Unlike most retail Intel 925-series, however, ECS/SiS implement 2 IDE ATA133 ports, great if you're still using a bunch of older hard drives and/or optical devices. A 24-pin EPS 12v power connector is also something that we see on the majority of Intel boards. Indeed, thus far, and not looking to the left, this could quite easily be another generic i925XE we're reviewing. http://www.hexus.net/content/reviews/review_print.php?dXJsX3Jldmlld19JRD0xMTgx 13/05/2005 HEXUS.net : Review : ECS PF88 Extreme Hybrid Mainboard Page 3 of 24 Coming on down the board and steadfastedly ignoring the two BIOS chips (another hint), the SiS965 southbridge is a solid companion to the PCI-Express SiS656 northbridge. SiS integrates 4 independent SATA ports that can be setup in RAID 0, 1, 0+1, and JBOD configurations. Further, continuing the PCI-Express theme, it supports 2 x1 lanes. Amongst other notables, the '965 features 8-channel sound, albeit only AC'97, 8 USB2.0 ports, 6 PCI slots, and a Gigabit Ethernet MAC. SiS also has another southbridge, imaginatively titled SiS966, that supports high-definition audio, and it may well be included in a board revision. More SATA goodness is to be found via the use of Silicon Image's Sil3132 controller. As the name implies, it supports 2 ports, red on the PF88 Extreme, and rides off the preferred x1 PCI-Express lane. I've bemoaned the lack of PCI-Express peripherals in the past, so it's nice to see ECS specify it instead of a regular PCI-based 3112. It also gains points by supporting SATA2, and by consequence, Native Command Queuing (not present in SiS965). Software RAID 0 and RAID 1 are also available, as is RAID 5 and RAID 10 if run with the optional port multiplier. Other feature goodies include 2-port FireWire (VIA6307), 3 PCI slots, 8-channel sound routed through Realtek's trusty ALC850 CODEC, and a Marvell physical layer that serves as another routing device for the SiS965's Gigabit Ethernet MAC. The I/O section reflects the feature-set well. There's 4 USB2.0 (another 4 available via on-board headers), a single FireWire 1394a port, RJ-45 for Gigabit Ethernet, 2 Serial ports, and 6 speaker ports that combine to offer 8-channel sound. Given the PF88 Extreme's aggressive pricing of only £65 including VAT and the decent feature-set and layout on offer, ECS would already be on to a winner. But there's more, oh so much more to it. Remember the purple-coloured slot and the second PCI-Express x16 slots from the previous page? It's kind http://www.hexus.net/content/reviews/review_print.php?dXJsX3Jldmlld19JRD0xMTgx 13/05/2005 HEXUS.net : Review : ECS PF88 Extreme Hybrid Mainboard Page 4 of 24 of hard to miss them. That's how, in essence, ECS is able to turn the PF88 Extreme from an Intel-only mainboard into, at the moment, a S939 AMD Athlon 64-supporting board. Bought separately for just over £30 including VAT, ECS offers its SIMA platform converter card, the A9S. And there you have it. An add-in card that fits into the purple-coloured Elite Bus connector on the PF88 Extreme. The A9S supports all current Socket-939 CPUs and will also run dual-core X2s with a BIOS update. Power-delivery circuits and a 4-pin cable (that you remove from the mainboard and attach here) give the card the necessary power stability and juice. 2 DDR1 slots offer up to 2GB of system RAM that's run in dual-channel mode. ECS has chosen to go with incompatible DDR1 and DDR2 for AMD and Intel, respectively. It could have engineered the PF88 Extreme to run with LGA775 and DDR1, much like Intel's i915x chipsets. That would have eased the financial burden of switching over to AMD, as now you have to invest in not only a CPU but also in DDR1 RAM. ECS has tried to strike a balance between future-proofing LGA775, which is supported at 266MHz FSB and will rise in the future, and present DDR400 support for AMD's S939 CPUs. Given a choice, I'd liked to have seen DDR1 implemented on both sides. It would then have simply been a matter of purchasing the A9S and the S939 CPU of your choice. http://www.hexus.net/content/reviews/review_print.php?dXJsX3Jldmlld19JRD0xMTgx 13/05/2005 HEXUS.net : Review : ECS PF88 Extreme Hybrid Mainboard Page 5 of 24 ECS has used a SiS756 PCI-Express-compatible northbridge on the convertor card. There's very good, practical reasons for it, too. It carries the dual-channel DDR400 memory controller which connects up to the DIMM slots mentioned above. Being PCI-Express, it also feeds down to the second orange-coloured x16 slot on the motherboard. The first, used in an Intel-based setup, can't be accessed as the convertor card blocks the slot completely. Even if it could, it's mapped out for the SiS656 northbridge. In a conventional AMD S939 setup, the SiS756 is usually paired with the '965 southbridge; exactly the same southbridge that's already featured here. The convertor card, once positioned in the Elite Bus slot and activated by removing a bank of jumpers, disables the SiS656-SiS965 interconnect and forces the PF88 Extreme to run with the AMD-designed SiS756SiS965 combination, again through a 1GB/s interconnect. Having said that, power is still being delivered to the LGA775 northbridge. The space constraints of locating both an Athlon 64 socket and 2 DIMM slots are manifested in the inability to run a reference, PIB cooler that's shipped with high-end S939 CPUs. Note how, using Crucial Ballistix RAM, the first DIMM slot is blocked off, thereby inadvertently disabling dual-channel memory. http://www.hexus.net/content/reviews/review_print.php?dXJsX3Jldmlld19JRD0xMTgx 13/05/2005 HEXUS.net : Review : ECS PF88 Extreme Hybrid Mainboard Page 6 of 24 Installing an older AMD reference cooler or appropriate aftermarket heatsink cures the problem. A couple of Corsair XMS3200XL sticks have just enough room to breathe. Look back to the previous page and you'll just be able to make out a two rows of black jumpers between the first PCI-Express x16 slot and the Elite Bus connector. These need to be removed when engaging the A9S addin SIMA card. What you get is........ http://www.hexus.net/content/reviews/review_print.php?dXJsX3Jldmlld19JRD0xMTgx 13/05/2005 HEXUS.net : Review : ECS PF88 Extreme Hybrid Mainboard Page 7 of 24 Note how the A9S card and AMD cooler then block the access path to the first PCI-Express slot?. That's one reason why there's a second one behind. The A9S card is also the reason why there's 2 BIOS chips on the board. One for Intel and one for AMD. Once the convertor card is plugged in correctly, the board switches the BIOS to AMD's. The PF88 Extreme ships with just the Intel chip in place, and AMD's is supplied with the A9S card. http://www.hexus.net/content/reviews/review_print.php?dXJsX3Jldmlld19JRD0xMTgx 13/05/2005 HEXUS.net : Review : ECS PF88 Extreme Hybrid Mainboard Page 8 of 24 Once installed, the PCI-Express card is moved to the left. With an ATI RADEON X850 XT PE 256MB in situ one niggly problem arose. Accessing the clear CMOS jumper, which is on the far left, with the motherboard in a regular CoolerMaster WaveMaster case, is frustratingly difficult without removing the card. ECS should also have used a big-headed jumper, found primarily on ABIT boards. The same setup with an Intel CPU, cooler and DDR2 RAM in place. Much cleaner, but that's kind of obvious, isn't it? http://www.hexus.net/content/reviews/review_print.php?dXJsX3Jldmlld19JRD0xMTgx 13/05/2005 HEXUS.net : Review : ECS PF88 Extreme Hybrid Mainboard Page 9 of 24 ECS hasn't skimped on board features or packaging. The PF88 Extreme arrives in an oversized box that's replete with goodies. ECS bundles in a multi-purpose bracket that adds in 2 USB2.0 and a single 6-pin FireWire port. There's also a foot-long eSATA cable, designed to be used with Silicon Image's 3132 controller, attached to the back of a case, and provide on-the-fly connectivity to external SATA hard drives, usually in enclosures and powered from the mains. 4 orange-coloured SATA cables and black IDE/floppy cables are a nice touch. There's also a custom I/O shield, molex-to-SATA power connectors, and a decent manual, with colour illustrations, written in good English. I also liked the fact that ECS provided a one-touch software installation CD, which took care of many of the board's drivers without the need to install each one manually. On the software front, ECS adds in InterVideo's WinDVD 5, WinDVD Creator, WinRip 2. Pro Magic Plus, a Ghost-like app., ShowShifter, another media-related application, and InTouch, a remote-accessing tool, complete the bundle. http://www.hexus.net/content/reviews/review_print.php?dXJsX3Jldmlld19JRD0xMTgx 13/05/2005 HEXUS.net : Review : ECS PF88 Extreme Hybrid Mainboard Page 10 of 24 The PF88 Extreme arrives in two flavours. One is the regular bundle, as seen above. The other includes WiFi support through a USB extender and 802.11g dongle; handy for gaining a better signal than having the dongle plugged into the back. Pricing for the standalone PF88 Extreme is £65 including VAT for the regular bundle and around £80 including VAT for the WiFi-equipped version. You could add 50% to those prices if the board had, say, ASUS' name on and not ECS'. A decent bundle to go along with a well-featured board.The ECS PF88 Extreme's BIOS is a unique setup in that it has to cater for both Intel and AMD CPUs. When using either brand of CPU and appropriate BIOS, we see the following Phoenix AwardBIOS page. With respect to Intel CPUs, let's trundle on over to the frequency/voltage section first. http://www.hexus.net/content/reviews/review_print.php?dXJsX3Jldmlld19JRD0xMTgx 13/05/2005 HEXUS.net : Review : ECS PF88 Extreme Hybrid Mainboard Page 11 of 24 CPU ratio only presents itself when using unlocked/engineering sample Intel-based processors. I found it impossible to run with anything other than the default multiplier. More of an early BIOS issue than anything else. CPU Front-Side Bus can be set, with respect to a 200MHz FSB CPU, to anything between default and 450MHz. Further, the PCI bus can be locked to ensure that peripherals don't hinder overclocking efforts. PCIExpress speeds aren't expressly stated, though. CPU-to-DRAM ratios need to be doubled in order to correspond to what we're used to with other boards. For example, most i925XE's can be set to DDR533 using a 3:4 ratio. ECS, however, states DRAM frequency in DDR terms, so the same setting is achieved via a 3:8 ratio. Others available are SPD, 3:4 (DDR266), 3:5 (DDR333), 1:2 (DDR400), and 3:10 (DDR667, or SPD in the case of Crucial Ballistix DDR2 PC5400 RAM). ECS also offers up to 0.075v extra juice for the CPU and 0.15v extra for DDR2. I'd liked to have seen extra adjustment on both lines, really. Intel-based DRAM control was best left at default settings, which translated into 4-4-4-12 timings at DDR533 speeds. http://www.hexus.net/content/reviews/review_print.php?dXJsX3Jldmlld19JRD0xMTgx 13/05/2005 HEXUS.net : Review : ECS PF88 Extreme Hybrid Mainboard Page 12 of 24 A relatively low 12v line didn't impact upon board stability in any way. Voltages were consistent as any other board's, too. AMD BIOS It will come as no surprise that the PF88 Extreme uses a second BIOS that's used in conjunction with the A9S add-in, AMD-supporting card. Firing up the board with card, CPU and DDR1 in place shows, expectedly, a BIOS geared up towards S939 CPUs. Note the lack of parameter adjustment compared to the Intel's. There's no CPU or DDR voltage manipulation, although that may appear in later BIOSes. It's probably a sensible approach by ECS, given that AMD S939 CPUs are run off an additional card and not the motherboard itself. FSB frequencies range from 200MHz-232MHz, so it's not aimed at the enthusiast, either. http://www.hexus.net/content/reviews/review_print.php?dXJsX3Jldmlld19JRD0xMTgx 13/05/2005 HEXUS.net : Review : ECS PF88 Extreme Hybrid Mainboard Page 13 of 24 There's a reasonable degree of DDR parameter adjustment. Running with a couple 512MB Corsair's XMS3200XL sticks and leaving the settings on auto gave SPD timings of 2-2-2-5 1T, perfect for low-latency accesses. Using an original S939 cooler pushed up an FX-53's BIOS CPU temperature to 55c. Windows' load hovered at around 63c. Hot but not hot enough to prejudice results in any way. Heat is something that ECS will need to keep a close eye upon, especially when running with FX-55 or dual-core CPUs. The odd socket positioning, relative to most motherboards', didn't impact upon stability at all.

The board was manually updated to the latest available at the time of writing, being 16/04 and 25/04 for Intel and AMD, respectively. However, even with these builds, a few problems were apparent. The board would often freeze on the OS-loading screen, necessitating a reboot. Reboots often didn't function correctly and a cold start was needed at times. Further, I was advised not to run AMD's BIOS with 5x HTT setting applied. Once successfully in Windows, though, the PF88 Extreme, with both Intel and AMD CPUs, was a paradigm of stability. I'm adamant that future BIOS releases will cure the test board's ailments. A single OS? Adding in the A9S card and removing jumpers takes but a minute. One can turn the PF88 Extreme from an Intel-based motherboard to an AMD's in a jiffy. However, when attempting to load the PF88 Extreme's Pentium 4 edition of Windows XP Professional with the A9S in place, each attempt was meet with abject failure, usually resulting in the system rebooting just as XP finished loading. The culprit in this case appears to be Windows XP itself, which isn't happy going from a 2-CPU (well, HT-equipped P4) to a single-CPU AMD system. Going the other way around, from AMD to Intel, worked flawlessly. I'll be comparing the ECS PF88 Extreme's performance against two established motherboards based on Intel's premier i925XE and AMD/VIA's K8T890 chipsets. The PF88 Extreme purports to offer the best of both worlds, so it will be interesting to see just how competitive it is, in terms of performance, with two of the fastest boards on either platform. Explicit running speeds of the boards were as follows: 3630.8MHz - EPoX 5LWA+ (i925XE) - Intel Pentium 4 660 3600.5MHz - ECS PF88 Extreme - Intel Pentium 4 660 2405.4MHz -ABIT AX8 (VIA K8T890) - AMD Athlon 64 FX-53 http://www.hexus.net/content/reviews/review_print.php?dXJsX3Jldmlld19JRD0xMTgx 13/05/2005 HEXUS.net : Review : ECS PF88 Extreme Hybrid Mainboard Page 15 of 24 2399.8MHz - ECS PF88 Extreme - AMD Athlon 64 FX-53 Note that the PF88 Extreme's clock generator doesn't inflate the FSB, unlike EpoX's. Please bear the running speed in mind when comparing results. Other than clock speed, the PF88 Extreme, in both Intel and AMD guises, was setup in an identical manner to the two comparison boards. Looking at memory tests first. When using the A9S convertor card and AMD Athlon 64 FX-53 CPU, ScienceMark 2.0 would repeatedly crash before spitting out the result. That's the reason why there's no figure shown there. Note, that with identical settings, i925XE has almost a 10% memory bandwidth advantage over PF88 Extreme. Latency, too, is much, much higher than Intel's 925XE. http://www.hexus.net/content/reviews/review_print.php?dXJsX3Jldmlld19JRD0xMTgx 13/05/2005 HEXUS.net : Review : ECS PF88 Extreme Hybrid Mainboard Page 16 of 24 The performance colours to look out for are grey and orange, which represent the PF88 Extreme with either AMD or Intel CPUs. Pifast, though, runs just fine with the A9S card in place. In fact, the result is commendably close to a VIA K8T890's. On the Intel side of things, the PF88 Extreme is just over 5% slower than an i925XE, although 1% of that advantage is gained by using an inflated FSB. Our cryptography benchmark shows VIA K8T890 and PF88 Extreme/A9S neck-and-neck. The P4 variant lags just a little behind. http://www.hexus.net/content/reviews/review_print.php?dXJsX3Jldmlld19JRD0xMTgx 13/05/2005 HEXUS.net : Review : ECS PF88 Extreme Hybrid Mainboard Page 17 of 24 Commendable performance in KribiBench.

It seems as if ECS' Intel-based memory controller isn't as hot as, you guessed it, Intel's. http://www.hexus.net/content/reviews/review_print.php?dXJsX3Jldmlld19JRD0xMTgx 13/05/2005 HEXUS.net : Review : ECS PF88 Extreme Hybrid Mainboard Page 19 of 24 Once again, decent performance from the hybrid ECS PF88 Extreme. http://www.hexus.net/content/reviews/review_print.php?dXJsX3Jldmlld19JRD0xMTgx 13/05/2005 HEXUS.net : Review : ECS PF88 Extreme Hybrid Mainboard Page 20 of 24 There's nothing wrong with SiS' PATA controller. The average PATA read speed, from a 160GB Western Digital hard drive, is just where it should be. SATA performance is also right on the money. http://www.hexus.net/content/reviews/review_print.php?dXJsX3Jldmlld19JRD0xMTgx 13/05/2005 HEXUS.net : Review : ECS PF88 Extreme Hybrid Mainboard Page 21 of 24 USB2.0 performance is the best of the lot. SiS' 965 southbridge, in storage speed terms, is plenty fast enough. Low CPU utilisation on all three counts, too. Excellent performance on the AMD side of things, once again, eclipsing the benchmark laid down by a welltuned VIA K8T890 mainboard. A lack of comparative bandwidth and latency pushes the P4-based score down by over 1,000 marks when compared to a class-leading i925XE's. The breakdowns and can be viewed here and here. http://www.hexus.net/content/reviews/review_print.php?dXJsX3Jldmlld19JRD0xMTgx 13/05/2005 HEXUS.net : Review : ECS PF88 Extreme Hybrid Mainboard Page 22 of 24 A similar story unfolds in DOOM 3, where there's general benchmark parity with the A9S convertor card and a lack of throughput when benchmarked in standard LGA775 form. UT2003's results echo what's been written above. Motherboards are intrinsically boring. Their primary role is to act as a conduit for the other parts of a system; the base on which everything is built upon. Refreshes come and go, and each new iteration of chipset sees some feature integrated into a bridge, be it PCI-Express or SATA2. Other chipset makers then follow suit and status quo is quickly re-established. That's why it was a pleasant surprise to see one of the largest motherboard produces, Elitegroup Computer Systems (ECS) attempt to do something totally different with the PF88 Extreme. ECS took on the challenge of designing a single motherboard that could accommodate the latest platforms without the need for swapping boards over. The solution that ECS came up with, in respect of catering for both LGA775 and S939 chipsets, is a novel one. Through the use of a proprietory interface, Elite Bus, and a http://www.hexus.net/content/reviews/review_print.php?dXJsX3Jldmlld19JRD0xMTgx 13/05/2005 HEXUS.net : Review : ECS PF88 Extreme Hybrid Mainboard Page 23 of 24 separate add-in SIMA card, a user is able to change over from the PF88 Extreme's default LGA775 layout to S939 in a matter of minutes. On a technical level, it's accomplished by using a single, on-board southbridge that can be set to communicate with either northbridge, onboard or SIMA-attached. ECS also plans to introduce SIMA cards for AMD's S754 and Intel Pentium 4 CPUs, for extra platform flexibility. Breaking down the PF88 Extreme's attributes into manageable sections, the default configuration, sans SIMA card, provides for a competent SiS chipset-powered PCI-Express (single card) Intel LGA775-based system. All the features one would expect are thrown in, including 4 DDR2 DIMM slots, on-chip SATA, discrete SATA2, FireWire 1394a, 8-channel sound (non-HD, sadly), Gigabit LAN, and a bundle that reflects the board's deluxe nature. ECS' aggressive pricing ensures that the PF88 Extreme will retail for around £65 inc. VAT, and whilst the performance isn't quite up to i925XE standards and the BIOS could do with greater levels of adjustment, it's competent enough given the package's street price. Evaluating the PF88 Extreme in ignorance of its multi-platform support is missing the entire point of the board, really. Adding in the ~£30 A9S SIMA card, any choice of S939 CPU, and a couple of decent stick of DDR1 memory transforms the PF88 into a high-performing AMD motherboard. The BIOS is lacking, certainly, and 2 DIMM slots may not be ideal for all, but at least it opens up the way for you, the user, to experiment with the other side without having to install a new motherboard. It won't appeal to the die-hard enthusiast interesting in pushing components to the absolute limit, but system integrators should immediately recognise the value inherent in a fast turnaround of platforms. The one blot on ECS' multi-platform vision is the need to re-install or 'rescue' Windows XP when changing from Intel to AMD setups. I've been pleasantly surprised by the ease of switching between Intel- and AMD-based systems. With this initial release, it would perhaps have been prudent for ECS to run with DDR1 memory throughout, mimimising the upgrade/sideways cost of moving to AMD's S939 CPUs, via the optional SIMA card. I'd also like to see greater levels of BIOS adjustment, thereby pandering to the needs of the enthusiast, and a slight PCB redesign, with a single switch, rather than 20-odd jumpers, for enabling the SIMA card would be nice. ECS has brought something very new to the table - a motherboard that carries a number of modern features and one that opens up the way for multi-CPU support. In the oft-boring, stagnant world of motherboard design, the ECS ELITEGROUP PF88 Extreme is a breath of very fresh air. HEXUS.awards HEXUS.right2reply to follow...
