We tested with our standard group of game tests, which includes Aquamark 3, Far Cry, Doom 3, and Wolfenstein-Enemy Territory. Only tests run with the 7800GTX with 81.8x drivers were included. In some cases, we retested with this card and the 81.8x drivers to make sure that our results could be reasonably compared. We did not test with Half-Life 2 since the recent updates to Steam have caused all the benchmarks we have available to stop working. We are looking for a new HL2 benchmark that is compatible with the latest Steam version.

We also ran benchmarks with three new games: Quake 4, Splinter Cell - Chaos Theory, and F.E.A.R. The Asus A8R-MVP was at or near the top in every game test, both our standard suite and the newest game tests. This was frankly a bit surprising, since we just recently found top gaming performance with the Asus A8N32-SLI, based on the new NVIDIA Dual x16 chipset.

Results with the ATI X1800XT on the Asus A8R-MVP were very intersting. THe X1800XT was either tops or matched results in all games not based on Open GL engines. In games base on Open GL, like Quake 4 and Doom 3, the new 5.11 driver has made up most, by not quite all, of the performance advantage perviously held by the nVidia 7800GTX. Keep in mind that these results are our standard tests, with AA and AF turned off if possible. We have found that as soon as AA and AF are turned on the X1800XT is tops even in Open GL compared to the 7800GTX.

    What I should have said is that the BIOS memory option maxes out at 200, so why is there a need to raise memory timings to 3-4-3-8 when at 325x9.

    200 is the starting point (400DDR) in BIOS, and memory clock floats with the CPU frequency. Thus at 325 Clock Speed the memory set at 200 is running DDR650. Memory floats with clock frequency on almost every board we test.

    If you start memory at 166 (333), it would run at about 270 (DDR540) with the Clock Frequency set to 325. You may want to do some reading or ask some questions in our Forums to better understand how this works.

    Got it, checked out Zebo's article in forums, my bad for not checking this out earlier. Thus begins my foray into AMD64 overclocking.

    Many thnx for help.

    K great. Thanks for the quick reply wes :D

    Final question I promise, lol.

    At the 325 x 9 setting, how stable do you think the CPU would be @ load? For example, I'm going to be playing alot of BF2 and Quake 4 with this new set up. I was wondering if it will be atleast 6 hours stable in those games at load.

    What do you think?

    I'm also trying to see if I can tighten those dram timings a bit by adding more voltage. What are the tighest/stable that you got with a higher ram voltage? Reply

    Hey Wesley, Great Review!

    I was wondering a few things with this motherboard and the setup.
    First, do you think the clawhammer 4000+ would overclock better than the Diego?
    What voltage are you feeding your ram to reach such a high frequency?
    Do you suggest using the 246 x 12 or the 325 x 9 set up for games?
    Finally, what voltage are you feeding the PCIe slot? Also, why haven't you upped the voltage to your cpu core to maintain stability and go beyond 2 days? :)

    Our San Diego clocks almost exactly the same as the Clawhammer 4000+, but it runs cooler. I would choose San Diego. We tested both on this board, as we have done for the last few reviews, found performance very similar (we had a fantastic Clawhammer that may not have been typical), and moved to the 90nm CPU for future reviews.

    The OCZ TCCD RAM was only getting 2.75V-2.8V. My pairs really don't like or need more voltage to reach high overclocks.

    Which you use depends on your RAM. In most cases you can get tighter timings at 246 than at 325. The best speed is a balance of highest RAM clock consistent with tightest timings. There is no cut-and-dried answer to your question.

    I did not overclock PCIe, but the chipset and/or PCIe sometimes reauires a small voltage boost at extreme overclocks.

    If you check the OC page I am using 1.45V vCore which is a modest OC of .05V from the default 1.4V. It didn't reboot after 2 days, we had to move on to other reviews. It might still be running fine at 325x9 for all we know.

    Awesome. 1 Quick last simple question. Did you slowly up the FSB through the bios and reboot, then up it again? Or did you use a windows based overclocker program that asus provided? If using the reboot method.. how long did you let it run before rebooting and upping the fsb a little more. If windows method, how long did you wait before upping the FSB little by little? Thanks :D Reply

    I rebooted and upped the frequency a bit, went into windows, then rebooted and upped frequency again. Reply

    Hmm...this is looking pretty good. But GigE performance is pretty important for me -- if I get a separate PCI-E 1x GigE card, can I match the throughput of the integrated PCI-E chipsets, like the Marvel, etc.?

    Any recommendations for a card? From a quick look around, I've seen an expensive D-Link ($80), some assorted others (SysKonnect, etc.) at varying ranges. Any benches of these for reference?

    And if I put in two X1800XT's, I wouldn't be able to fit a 1x card in between, right? What about with single-slot cards like the X1800XL?
