Test Results: OCZ PC3200 Platinum Rev. 2
To be considered stable for test purposes, Quake3 benchmark, UT2003 Demo, Super PI, Aquamark 3, and RTCW had to complete without incident. Any of these, and in particular Super PI and Return to Castle Wolfenstein, will crash a less-than stable memory configuration.| OCZ PC3200 Platinum Rev 2 (DDR466) - 2 x 512Mb Double-Bank | |||||||

The impact of the upgraded power supply on Athlon 64 memory testing is probably most obvious in our tests of OCZ Platinum Rev. 2. This is the second TCCD memory to reach DDR600 on the A64, much better than what the DDR 557 achieved in memory testing on the Intel test bed.
As impressive as DDR600 sounds, you should remember that this was achieved with a 2T Command Rate. Actual Performance at DDR600 was therefore about the same as 1T performance at DDR533.
The most impressive performance with 3200 Platinum Rev. 2 was the ability to run at a 1T Command Rate at DDR580 - the highest 1T performance achieved in this roundup. At that speed, performance was truly exceptional, with the highest benchmark results achieved.

I ordered from Newegg today. I did not see a place on their site for just a 512mb stick. I ordered the 1gb kit.http://www.newegg.com/app/ViewProductDesc.asp?desc...

hey bugler where are you ordering your ocz platinum rev. 2 from? is there any way to find a place where you can order 1 512mb stick only?darkwaffle - Friday, October 1, 2004 - link
I'm curious, for a socket754 user, is there really any reason why we couldn't (generally) follow these results? I realize that some of the overclocks may not be able to be achieved, but is it safe to say that the modules that perform highly on s939 will also perform highly also on s754 (In comparison to the other modules)?Wesley Fink - Friday, October 1, 2004 - link
#32 -Corsair and Kingston DDR400 2-2-2 were both included in our recent 2-2-2 roundup. Frankly we did test both Kingston and Corsair in the early going for these tests and both did quite poorly on the Athlon 64 test bed compared to other recent TCCD modules.
However, the Kingston and Corsair were early TCCD dimms and we are confident more recent dimms from these two major manufacturers would perform more like the OCZ, Geil, and G. Skill. Unfortunately we didn't have those more recent dimms to test, and we felt reporting what we had found would have been very unfair to Corsair and Kingston, who both produce excellent memory products.

I'm sure OCZ and Geil are great memory for A64, but all I got out of that article was buy OCZ memory, buy Geil Memory, o ya and buy a top of the line OCZ power supply....What about Corsair and Kingston? How do they compete?
This site is smothered with advertisement. Why make it so obvious in the articles? Thanks for the article though...

And re: the robust +12v rails. They are most crucial for A64 overlocking. I have an Enermax with 31A on two +12v rails and it makes the world of difference.einsig - Friday, October 1, 2004 - link
One thing that really needs to be stated is that Clawhammer cores automatically set a command rate of 2T at speeds from DDR400 and up. you need to use A64 Tweaker to make the change (can be loaded at startup). I have a Clawhammer 3400+ that has been run on an ASUS K8V Deluxe and MSI K8N Neo Platinum. I was running XMS 2x512 3200LL Corsair, but it didn't want to OC even on the K8N (nothing OCs on the K8V because of the chipset). I now run Crucial ballistix PC4000 and it is incredible, however (as the article states) the command rate of 1T is really ideal. They should just tell people how to set that if they have a Clawhammer.Shinei - Friday, October 1, 2004 - link
What's really exciting is that the two DDR600 overclockers are board-limited before they top out in speed (K8N Neo2s go to 300MHz on the RAM). I'd like to see what the RAM could do on a more extreme overclocking board, since it seems like these new RAM chips are capable of pushing on to DDR667 or even higher...With that said, I agree that the prices for this stuff is getting ridonculous. Cheaper RAM means more sales and increased usage of that 8 exobyte storage capacity the Athlon 64 has. ;)

Thank you AnandTech. I have been waiting for greater clarification since you last recommended OCZ 3700 enhanced bandwidth ram and none could be found. I was balancing between that and ballistix. After today's review, I ordered OCZ Plat, rev 2 for the system I am putting together.Now if we could get some reviews and testing of the newer 90 speed AMD processors, hint, hint...
I appreciate this site very much.
