Winfast NF4UK8AA (Foxconn): Overclocking and Stress Testing

Overclocking

Front Side Bus Overclocking Testbed
Winfast NF4UK8AA
Processor: Athlon 64 4000+
(2.4GHz, 1MB Cache)
CPU Voltage: 1.55V (default 1.50V)
Cooling: Thermaltake Silent Boost K8 Heatsink/Fan
Power Supply: OCZ Power Stream 520W
Memory: OCZ PC3200 EL Platinum Rev. 2
(Samsung TCCD Memory Chips)
Hard Drive: Seagate 120GB 7200RPM SATA 8MB Cache
Maximum OC:
(Standard Ratio)
235x12 (Auto HT, 2-3-2-7, 1T, 2.9V)
2856MHz (+19%)
Maximum FSB:
(Lower Ratio)
NO RATIO Settings Available
235x12 (Auto HT, 2-3-2-7, 1T, 2.9V)
2856MHz (+19% Bus Overclock}

It is really a shame that Foxconn Winfast does not provide any options for adjusting the CPU multipliers. At stock speeds, the Winfast NF4UK8AA was one of the better performing boards, and overclocking at stock multipliers was very good, reaching 235x12. Of course, you can't test 9x318 if multipliers aren't available, so the highest standard ratio overclock of 235 was also our highest bus overclock. We hope that Foxconn Winfast will address this oversight in an upcoming BIOS because the lack of multipliers makes this board one that no enthusiast would really consider for purchase.

We are convinced that the Foxconn can deliver a lot more than what we were able to test in this roundup, and we sincerely hope that a BIOS update will bring the Winfast into a more competitive position against the better boards in this roundup.

Memory Stress Tests

Our memory stress test measures the ability of the NF4UK8AA to operate at its officially supported memory frequency (400MHz DDR), at the lowest memory timings that OCZ PC3200 Platinum Rev. 2 modules will support. All DIMMs used for stress testing were 512MB double-sided (or double-bank) memory. To make sure that memory performed properly in Dual-Channel mode, memory was only tested using either one dual-channel (2 DIMMs) or 2 dual-channels (4 DIMMs).

Stable DDR400 Timings - One Dual-Channel
(2/4 DIMMs populated)
Clock Speed: 200MHz
CAS Latency: 2.0
RAS to CAS Delay: 2T
RAS Precharge: 7T
Precharge Delay: 2T
Command Rate: 1T

Using two DIMMs in Dual-Channel 128-bit mode, the memory performed in all benchmarks at the fastest 2-2-2-7 timings, at default 2.6V voltage.

Tests with 4 DS DIMMs on an AMD Athlon 64 system are more demanding, since AMD specifies DDR333 for this combination. However, most AMD Athlon 64 motherboards combined with recent AMD processors (the memory controller is on the AMD CPU) have been able to handle 4 DIMMs at DDR400.

Stable DDR400 Timings - 4 DIMMs
(4/4 DIMMs populated)
Clock Speed: 200MHz
CAS Latency: 2.0
RAS to CAS Delay: 2T
RAS Precharge: 7T
Precharge Delay: 2T
Command Rate: 2T

Tests with all four DIMM slots populated on the Foxconn showed that the board was stable at the same 2-2-2-7 memory timings used for 2 DIMMs, but with a 2T Command Rate required. This is the pattern seen on other top-performing Socket 939 boards. 2T was also required for 4 DS DIMMs with a new Rev. E processor and the improved memory controller.

    Does ECS build EPOX's boards? just curious because they look pretty cheap like ECS IMO..

    "[b]#19 and Others - I'm sure you must have noticed that some web sites have never posted a negative review of an Abit board. Also water cooling and asynchronous ram is hardly comparable to our air-cooled tests.

    The first thing I did was check other reviewers and users of the Abit board. The great majority are running into problems at about 250 FSB - although a few are getting better performance. Abit has had so many complaints about the OC performance of this board that I would fully expect a hardware revision on the horizon.[/b]"
    Well the Fatality AN8 SLi, AN8 SLi, AN8 Ultra, AN8 V2.0 & AN8-V are effectively the new revision as I pointed out. Why buy a Fatality AN8 when the AN8 Ultra has better Vcore, better sound & is cheaper?
    & people have had HTT395 & DDR660 out of them on air ...

    Abit set the expectation that the AN8 Fatal1ty was the best of the best with a price tag to match. It's an interesting board with many interesting features, but it's performance as it now stands is nowhere near the best.

    I think that a round up such as this would serve the readers better if three types of memory were used and various dividers used.
    My Chaintech VnF4 is running at 256x11 quite happilly, so I know it will run well over 245 with a divider with my memory, and I'm sure most of the other boards as well. And yes, many people run it over 300 HTT with lower multi cpu's.
    This is not to say that 1:1 testing is not important, but since this is a round up, the various needs and budgets of your readers should be taken into account.
    Seeing bios's used that are dated during the testing, with a known single memory may if repeated cause readers to think that Anandtech doesn't deserve it's well earned reputation as a fair and complete tester of all things important to PC ethusiasts.
    Using memories with 3 different types of chips and using relevant dividers to find maximum HTT's and cpu speeds with each, while being more work, I think will be worth while to your readers, especially in a round up where boards are compared directly to each other.
    This current round up implies that most nF4 boards are not capable of high HTT's, but the truth is you have only shown that most do not run one type of memory at very high speeds. You have not exposed the limits of the boards, nor do we know if the situation is the same with any of the other commonly used memories.

    Xpose-
    Not too early. I don't have my board yet. I have been waiting on X2. Using your same logic that means that nobody has a board yet right? I mean, since I am the only person I know that is going to build a A64 system soon then I should assume that nobody has one.
    Geez

    This Editor's Recommendation for best motherboard is at least 3 months too late. We already have had all of our boards.

    Also, to say that the VN4F Ultra is a bad overclocking board is completely wrong. I have a 3000+ CPU running at 2.67gz now. That is about 49% OC and damn good reguardless of the MB.

    great article! you can clearly see the hours of hard work you put into it. Great Job, I enjoyed it and it was jam packed with info.

    one quuestion though where was the gugabyte board ultra board?? sure you may have reviewed it in the SLI roundup, but then did you not do the same with DFI? Plus you had great results with the reference gigabyte board, but not the revision 1 board...i'd like to see how ir fairs now...maybe i missed something why you reviewed the DFI board again becuase I am not familiar witha ll their variations and naming scheme, but to me it looked the same...why review that one and not the others? sure its great to rehash what a great board the DFi one is but....

    just wondering as I have always had great success with gigabyte boards...but i probably missed something even thought i read it back to front, sorry if i did as i know that you would never do something without a good reason behind it...

    anyway thanks, keep the awesome articles rolling...

    Hi Wesley, thanks for the clarification on the HTT. do you know if it would have any more of an impact when dual core is brought into the equation?

    Thanks again. Good article BTW!

    #18 I really like that idea, would probably be a headache to make it and keep it updated though.
