Athlon 64 Memory: Rewriting the Rules

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.

If you get the chance, can you please test with 2GB of PC3200? I’m sure most would love to see what type of performance hit there will be with the larger modules vs. the smaller ones. Looking at the benches so far, it looks like even buying the cheap 1GB PC3200 modules will have negligible impact on the performance as long as the times are kept relatively low (under 3cls.) And one more big IF you could test 4x512 PC3200 with lower clock timings (2-2-2-5) vs 2x1024 PC 3200 with timings of (3-3-3-8) I’m sure that for the average user they would rather blow $400 for 2GB of slow memory then $400 for 1GB of fast memory.Zebo - Friday, October 1, 2004 - link
spensive!:(p/p is horrendous for this stuff. It's too bad you don't include micron/crucial 8t in there which can also clock to 260 for half the price.

I've loved all of these recent memory articles. For a while now, the current state of memory in general has been the fuzziest for me. Now I'm starting to get a clearer picture of where things are at and which direction to go. I'm still nursing along my old P4 Northwood, but the A64 plunge is imminent. Nice to see that memory development is keeping up at a strong pace what with 600 MHz speeds now a strong reality.RaistlinZ - Friday, October 1, 2004 - link
Thank you for the great article! From your tests it looks like the OCZ 3200 Rev.2 is the best of the best. It performed near the top in every test and edged out the Crucial Ballistix at the highest speeds.I guess my choice for a memory upgrade is clear now. :)

Seems you cut something off at the end of page 9"We have asked AMD to provide some insight into why we are "...

excellent article, ill keep this in mind when I upgrade... im still pluggin on a TbredB @ 2.2 w/ a modded 9500nonpro
