Performance Comparisons
Performance of the three 1GB memories were compared to all of the memory recently tested on the DFI nF4 AMD Athlon 64 platform. Results are also generally comparable to earlier results on the nForce3 testbed using the AGP version of the same NVIDIA 6800 video card. The performance differences will be that the NVIDIA 78.01 driver is a bit faster than the 61.77 and 71.84 drivers used in earlier memory reviews.
We no longer test DDR on an Intel platform because all of the current Intel chipsets use DDR2 memory. However, the performance results that we found on the AMD Athlon 64 platform can be broadly compared to previous DDR benchmark results on the Intel 875 memory test bed.

Corsair CMX1024-3500LL PRO, Gigaram 2GB Dual Channel PC-4200, and OCZ PC4000 1024MB EB Platinum were compared at 200x12 (2.4Ghz, DDR400), 218x11 (2.4Ghz, DDR438), 240x10 (2.4Ghz, DDR480), 266x9 (2.4Ghz, DDR533) and the Highest Memory Performance Settings that we could reach. With a constant CPU speed, memory comparisons (except for top performance) show the true impact of faster speed and slower memory timings on memory performance.

Does 4 single sided 512MB sticks behave the same as 2 double sided 1GB sticks?eastvillager - Tuesday, October 11, 2005 - link
Why would you buy these when the 2-3-2-5 sticks are readily available?Wesley Fink - Tuesday, October 11, 2005 - link
If you read the review you will see that ALL THREE of the 1GB dimms ran at 2-3-2 at DDR400 to DDR440 or so. They will all run 2-3-2-5, but we have shown in previous tests the the nForce 4 is fastest running a tRAS of 6 or 7. We ran 2-3-2-7 because it is faster than 2-3-2-5 on the nForce4. Try it for yourslef with memtest86 and differnet tRAS.Sunrise089 - Tuesday, October 11, 2005 - link
Possible minor typos aside, this article is a great change of pace from some of the recent technical write-ups here on Anandtech(cough:R520:cough). The quality of writing as well as the attempt to put the parts in perspective and give the big picture is much appreciated. With so many sites out there, I can go anywhere for simple RAM benchmarks, but for me it is much harder to find informed discussions about why the part being reviewed is a good idea/choice or not. I really felt this side of the story was lacking in the X1800 reviews and am glad to see it here.Houdani - Tuesday, October 11, 2005 - link
Page 3:I think you meant DDR550.
Page 4:
In your table of memory, you list the 3 new sticks as 2x512. I think you meant 2x1024.

Corrected. Thanks for bringing these to us. It's funny that they looked just fine at 3AM :-)Doormat - Tuesday, October 11, 2005 - link
Whether its worth it or not to invest heavily (these pieces arent cheap) in DDR1 tech if you've already got a pair of fast running 2x512MB sticks. You'll just have to buy DDR2 sticks in a year if you want the fastest stuff (an A64 M2-socket based chip).emilyek - Tuesday, October 11, 2005 - link
Lame. Why not a big review on the many available 2 and 2.5 cas DDR 400 sticks? The Geil, Patriot, OCZ, Gskill, and Corsair already top out at about 1k FSB when loosed up, and the timings on these RAMS sucks anyway.DrMrLordX - Tuesday, October 11, 2005 - link
They've said it before, and I'll say it again: you just can't add every available DIMM variety to RAM tests. There's too much on the market, and many of the budget RAM types have wildly variable quality and performance.RockSolid - Tuesday, October 11, 2005 - link
The RamGuy link on Page 5 is incorrect.
