High-Resolution Gaming Performance
We are using the same game benchmarks in our standard gaming performance section that consists of Serious Sam 2, Half Life 2: Lost Coast, F.E.A.R, Quake 4, and Battlefield 2. All boards were tested with the EVGA 7900GTX using NVIDIA 91.31 WHQL drivers. The Intel 975X boards were also tested with a single ATI X1900XTX card with the Catalyst 6.6 driver. The SLI results on the ASUS P5N32-SLI SE utilized two EVGA 7900GTX cards and the 91.31 drivers with profiles enabled for each game. The CrossFire results on the Intel 975X boards utilized our ATI X1900XTX and X1900 CrossFire Edition cards with the 6.6 Catalyst driver.
The single card 1600x1200 results with the EVGA 7900GTX card shows the ASUS P5N32-SLI SE taking a clean sweep of the benchmarks. The performance of the 7900GTX and nForce4 Intel Edition chipset made a small but measurable difference at the higher resolutions as the boards started to become GPU bound. Due to the strength of the NVIDIA SLI setup along with obvious ATI issues in the Half Life 2: Lost Coast and Quake 4 benchmarks this same board sweeps our multi-GPU tests.
However, we also noticed where the ATI cards made a very strong showing in our standard benchmarks in F.E.A.R. and Serious Sam 2 by finishing first, they fell behind the SLI setup when running CrossFire indicating a lack of optimizations or possible driver issues in our tests. The performance percentage drop of the ASRock board compared to the other boards when moving to 1600x1200 was even greater than at 1280x1024 indicating that X4 PCIe operation is certainly hampering its performance.

Actually, heck, I'm not much of an overclocker at all (I know that makes me the minority here). I'm looking at the Core 2 6600 at its native 2.4Ghz, 4Mb L2 Cache & 1066Mhz BUS Speed and figure that should be seriously fine for me.In regards to memory, I'd much rather purchase 2Gig's @ $180.00 than at $450.00 and since I'm not overclocking that shouldn't be a problem. But what I would have liked to have seen in this article were value sticks rated at DDR2 800Mhz as opposed to 667Mhz. So I anxiously await a "value-ram" roundup article of some sorts to not only show us what memory modules work well in the various mobo's but also which sticks can operate at those frequencies with low timing.

The Buyers Guide shows all the Value Ram operating at DDR2-800 at 4-3-3-3 at around 2.2V. We also show the timings and voltage of the value Ram at 667, 533, and 400, in addition to 800.jonmcguffin - Sunday, July 23, 2006 - link
Correct, but the ratings from the manufacture don't have those memory module's spec'd at DDR2-800. You were overclocking them essentially. Check out theCorsair 2Gb TWIN2X2048-6400 DDR2-800Mhz set. These two sticks are rated at DDR2, sell for $160 - $170 and run at 5-5-5-12-T1 timings at 1.9V.
I would consider these a good starting point. Again, I'm not necessarily into running anything beyond the manufacture's claims, but for this price, it would seem these memory modules would fit the bill for a lot of users out there.

All,I received a new beta bios from Abit today. I will be testing it later and will provide a quick update before we publish our final review on the board. Abit has spent considerable time this week testing this bios before release to us and hopefully it will fully address the memory setting issue we first reported in our preview issue.

I dont know where you priced your motherboards for this review, but I purchased the DFI 975x/g on july 18th from zipzoomfly for $187. It shipped the next day and I should see it today or Monday.Given that the DFI board is available for $62 less than your article shows, I think I made a good choice, since I dont need to overclock or run any high end graphics.
Now I just need to get my hands on a cpu. This is for a work computer, but after things settle out around octoberish I will upgrade my home gaming setup with the conroe. I am playing titan quest right now, and even with a geforce 7950 the game hitches quite a bit in certain areas at most resolutions.. I figure increasing the cpu power will help substantially, at least thats my excuse for upgrading.

The price was taken at the time the article written (17th) based on pricing from three different suppliers that had the board in stock. Now that ZipZoomFly (would assume others shortly) has it in stock at a price point (slightly below) that we had discussed with DFI I will update our article. The 7950GTX has not been qualified on this board yet so performance issues could occur since the required bios optimizations between the board and card are not completed. We really like this motherboard and for the $187 price, it is a great value now and one that should be seriously considered for purchase by early Core 2 Duo buyers. Although, we expected more in the way of overclocking, a very solild 375FSB is nothing to sneeze at and stock performance is excellent. Thank you for the price update! :)Gary Key - Friday, July 21, 2006 - link
Where is the edit button?a very solid.....

I am looking for OC a E6600 with 4MB cache to 4Ghz with minimum budget and I never OC my system. So I don't know which value board/RAM would meet the target. I don't care about timing/latency. I would like to see anandtech to publish guides for high performance OCers and value OCers and help us to reach max speed.In addition, I can pickup DDR2-800 RAM priced similar to those 667 RAMs, I don't understand why they are not included in review?
Thanks.

We will have additional guides in the near future. As for the DDR2-800 memory, we will be looking those modules in a mid-range section and a couple of the lower end that we have tested did not do any better than the high end DDR2-533/667 from a timing viewpoint or a high speed. Getting a E6600 to 4GHz is not that easy with a minimum budget but your suggestions are noted for the next guide. Thank you for the comments. :)Roy2001 - Friday, July 21, 2006 - link
I know minimum budget system won't be easy to hit 4Ghz speed. I am not too sensitive to the money, but I just don't want to spend $450 for best RAM while I can hit 4Ghz with $150 RAM. Same thing happens to motherboard. I don't care 1394 port, optical port, as long as it is stable @4Ghz, I just pick the lowest priced although I can afford a $250 mother board. Hope that helps as I think I am not alone. Thanks for your hard work!
