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.

    Thanks for the review. I've been toying around with 4 sticks of Ballistix pc3200, only to get them running at 480mhz with 2.5-3-3-8 2T timings (I got 530mhz with 2 sticks at 1T). It's not too bad, but after reading this, I decided to replace them with the 2x1024 OCZ pc4000. I actually have 5 sticks of Ballistix, and I'm hoping to sell them for 50$ each. Anyone interested?
  • AkumaX - Wednesday, October 12, 2005 - link

    I think on Page 2 when you were comparing 2T vs 1T you also meant 2x1024mb vs 4x512mb, rather than 2x512mb vs 4x512mb right?
  • cryptonomicon - Wednesday, October 12, 2005 - link

    no, he's comparing the same ram to show how the memory controller goes to crap after you load up more than two dimms. the sticks were both 512x2 plat rev II

    Nice, well-written article, Wesley. It seems slightly ironic to me, though, that this review comes out just as I'm expecting a 2GB kit from G.Skill via NewEgg to arrive tomorrow to replace my el-cheapo 2x512 (3-3-3-7 at DDR400? ick)

    Minor nit: pg 8
    "The performance differences will be that the NVIDIA 71.84 driver is a bit faster than the 61.77 and 71.84 drivers used in earlier memory reviews."
    Umm ... unless the driver is somehow faster than itself, I'm hoping that's a typo of sorts.

    I'm glad to see a review on 2x1024 MB; it was past due.

    I realize there aren't many DDR433 & up 2x1024MB RAM manufacturers, but i would have liked to have seen Crucial, Mushkin, Patriot, Geil, since they all make good DDR400 kits, & at least in Mushkin & Crucial's case, they also make DDR433 & up kits.

    To make it simple, i'd like to see a review with a few more companies involved :)

    Isnt it a little unfair to say one brand highest speed obtain @ 2-3-2-7 is lower then some other brand higest speed obtain is higher cause of 3-4-3-7? I mean, if you set corsair at a more lax timing AND higher voltage wouldnt it do better? Some one fill me in. Cause i remember back in the old days, memory i bought that can do 2-2-3-6 at 2.5v that was rated at 400DDR would overclock and do much better the same timing and voltage of some-old brand 533DDR+.
  • Wesley Fink - Tuesday, October 11, 2005 - link

    From p. 5 of the review:

    "Increasing voltage beyond 2.7V did not allow us to go any higher in overclocking, nor did more relaxed timings allow us to push higher. The limit is DDR492 - very close to DDR500."

    We tried to go higher but DDR492 is the limit with the 1GB Corsair dimms we tested. As we stated in the review it is likely Corsair is using a different Infineon chip than OCZ and Gigaram, or they are binning for best performance in the DDR400 to DDR500 range. Gigaram and OCZ are probably also using different Inineon memory chips - or they are at the least using different binning methodologies.

    wow.. wesley, long needed article. however, some silly mistakes that i think i see :D
    first.. the gigaram oc'ing chart. max speed is put at 2-4-3-7.. are you sure it's not 3-4-3-7?
    also, the second speed is curiously 2-2.5-2.. where 2.5-3-2 is exepcted

    second, i know the difficulties of getting review samples, but where is the biggest name in 1gb sticks right now, crucial ballistix? i have seen many of these sticks do 280-300mhz.

    last, i remember the value ram overclocking article you guys had a while back. plan on going the same for 1gb sticks?
  • Wesley Fink - Tuesday, October 11, 2005 - link

    I went back to my test logs and corrected the misplaced values. DD436 is 2-3-2-7 and DDR556 is 3-4-3-7. The second value in all reported strings is RAS to CAS Delay in case anyone is confused by the notation.

    We hope to do a review of the Crucial Ballistix 1GB dimms in the near future. We haven't decided whether to do a Value 1GB roundup yet, but we will consider your suggestion.
