Performance Comparisons
Performance of the OCZ EL PC4000 VX Gold, Corsair TwinX1024-4400C25, Crucial Ballistix PC3200, and OCZ PC3200 Platinum Rev.2 were compared on the DFI nForce4 AMD Athlon 64 platform. While we did not test on an Intel platform, the performance results can also be generally compared to previous benchmark results on the Intel test beds. More results are available in recent DDR memory reviews at:OCZ VX Memory + DFI nForce4 = DDR533 at 2-2-2

Searching for the Memory Holy Grail - Part 2
OCZ EL PC4000 VX Gold, Corsair TwinX1024-4400C25, Crucial Ballistix PC3200, and OCZ PC3200 Platinum Rev.2 were compared at 200x12 (2.4Ghz, DDR400), 218x11 (2.4Ghz, DDR436), 240x10 (2.4Ghz, DDR480), 267x9 (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.

Thanks for the great review & follow-up. I purchased 2GB of this stuff (based off your initial review), well 1GB, but the Egg rocks so hard they sent me 1GB free :) I'm having issues breaking 250FSB.Wesley, I was wondering what DRAM settings & Genie BIOS settings you are using in this comparison. I've tried a bunch of settings posted at DFI Street & Bleeding Edge, but to no avail. I'm also curious as to whether active cooling is being used on the memory. Anything past 3.2V on my OCZ VX RAM gives me errors.

#20, he wasn't talking specifically about this article.And he makes a point. AnandTech is lacking reviews for AMD PCI-E boards, so far there's only a 4-boards SLI roundup, an article for the DFI boards and reviews of pre-production Gigabyte boards. That's too little for a site like AnandTech and I have to say I'm a little disapointed.

#10 The reason no other boards are reviewed in the article, as it plainly states, is they don't have enough memory voltage. The only way they can be used is with the OCZ voltage adapter. This would not be a comparable test though.L3p3rM355i4h - Wednesday, March 30, 2005 - link
TCCD isn't the holy grail of RAM anymore. Too bad you need a DDR booster or a DFI mobo to take advangtage though.Viper4185 - Wednesday, March 30, 2005 - link
Thanks for the reply guys, i'll check it out now :PSpacecomber - Wednesday, March 30, 2005 - link
When you run MemTest86, you'll notice in the upper left part of the screen that it gives you some information, including memory bandwidth numbers for the cache and the system memory. The system memory number is what AnandTech is looking at to determine if certain memory timing settings are increasing the memory bandwidth or not.Space

#15 have a look at www.memtest86.org, download either the floppy version or thr cd ISO file and create the memtest disk. Set to boot from it.once running memtest you can press C then 9 for the advanced options, this will allow you to set memory timings from within memtest its self without the need to reboot.
you can also press c 9 then 5 for the advanced A64 memory options and tweak your ram even further.
All this is done before you load the OS so your HDD will not be at risk of data corruption.
Also the latest builds of the DFI bios files have memtest85 incorperated into them in genie bios so you don't have to compile a disk at all, just set enabled and the pc will boot to memtest on its own.

Sorry to be a n00b but are you saying that the memtest86+ program that fits on a floppy can actually tell me the best settings for my setup? If so how? As soon as i boot the computer and run it it just goes through all those 8 tests it does...Wesley Fink - Wednesday, March 30, 2005 - link
Ozzimark -We have been running Everest in our memory tests to start to build a database. We just weren't ready to introduce a new bench in this update.
I did notice a very interesting trend in Everest while testing these memories. The Read values were pretty close at the same speed, but VX had a significantly higher Write score than any other memory tested here. At DDR400 the write scores for TCCD were in the 2100 MB/s range where VX write was 2661. Ballistix scores were closer to VX than TCCD.
