Test Setup
Tests used OCZ PC3200 Platinum Rev. 2, which uses Samsung TCCD chips. All memory ran at 2-2-2-7 timing in all benchmarks.
We tested with the NVIDIA 7800GTX using nVidia 81.85 drivers to provide the most up-to-date performance results. We also ran graphics and games benchmarks with the MSI RX1800 (X1800XT) using Catalyst 5.11 drivers. Resolution in all benchmarks is 1280x1024x32 unless otherwise noted. 3DMark and Aquamark3 benchmarks use "Standard Score" setup, which is 1024x768 video resolution.
Results for the Asus A8R-MVP are in red. Test results for other motherboards are in blue.

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.Wesley Fink - Sunday, December 11, 2005 - link
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 :DFinal 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?EnlightenedOne - Thursday, December 8, 2005 - link
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 :DWesley Fink - Sunday, December 11, 2005 - link
I rebooted and upped the frequency a bit, went into windows, then rebooted and upped frequency again.abakshi - Wednesday, December 7, 2005 - link
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?
