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.

This memory rocks. Can someone please do me a favour of buying this memory for me from newegg, ship it to me (UK/HK) and I'll pay him cost + postage + a bit extra via paypal. Thanks very much. It's a bit annoying since you cannot buy this ram from HK. No suppliers.Just e-mail me at annihilator@x-annihilation.com
Thanks again

*notes that it's 245mhz at 2.5-2-2-10ozzimark - Wednesday, March 30, 2005 - link
#28my ballistix can go to 245mhz with 2.7v before my memory controller starts hating me and having some serious stability issues. though they seem to scale nicely with voltage, i can't really test it out, because even at 3-4-4-10 with 2T, i can't get over 250mhz.

AnandTech should do a review of the TwinMOS UTT chips that cost $150 less than the VX. I bought VX before I heard about the TwinMOS stuff, but my friend is doing 2-2-2-6 at 255MHz with 3.4 volts at 1:1. My VX can do 260MHz, but I would give 5MHz RAM/FSB bandwidth and 50MHz core for $150 any day.JoKeRr - Wednesday, March 30, 2005 - link
one more thing, I've heard from many ppl that they're running their BH5 sticks (2x512) to 250 2-2-2-5 with like 3.1 to 3.2V, if u still do have some old BH5, would it be possible to lay a show down between bh5 and VX?? I think I saw a guy on xtremeresouce /or maybe system doing ddr293 with 4V with mushkin BH5 at 2-2-2-5 timing, that's crazy.JoKeRr - Wednesday, March 30, 2005 - link
How does the Ballistix react to voltage?? I've heard that Tccd doesn't react very well, but the old EB stuff could do 2.5-2-2-5 at ddr500 once u give it 3.1V. Could you plz try that and see how the Ballistix scale with voltage plz?? thankQ in advance.JoKeRr - Wednesday, March 30, 2005 - link

23-If you are trying to get 2 gigabytes to do those speeds in tandem with the CPU, you'll have problems. Try using the regular 2*512 instead of 4*512 and see you can hit 250 fsb at 2-2-2.
Or ask the OCZ guys, they're very helpful.

hmm, my bad, the [img] tags don't work here. just copy and paste that link :)and since it seems that some posts have been deleted, my above comment is in response to #13

#14-that's quite interesting. maybe the spd's on the ram sticks are changing important values other than the cas, trcd, trp? i know that there are a lot of values that effect ram performance other than those three. i actually went through most of them on the dfi board, and found that lower isn't always better, similar to tras. though with that you said, i may have to go through and re-tweak my setup with the write benchmark in mind too. i never really gave it much thought assuming that it would scale similarily to read bandwidth.
also, i noticed some inconsistancies at various multipliers. i tested at two speeds, 230mhz (near the limit of my memory controller) at 2.5-2-2-10, and 200mhz at 2-2-2-10. (i use 2x512mb of crucial ballistix)
the only thing changed between runs is the cpu mutliplier. the ram is 1:1, and everything else remains constant.
