Athlon 64 Memory: Rewriting the Rules

Highest Memory Performance
Since the introduction of Athlon 64, we have learned that Command Rate is very important to memory performance in A64 boards. A Command Rate of 1T is significantly faster than memory running at 2T. This series of charts really shows how these six memories perform at the top.
While memory performance at the top is influenced by memory timings, the top performance on Athlon 64 correlates well with the highest 1T memory speed that each memory could achieve. The winner in this benchmark was the OCZ PC3200 Platinum Rev. 2 and it is also the top performing memory in the roundup. Other memories are faster in lower speed ranges, but the fast 1T performance wins at the top.

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 "...
