Performance Test Configuration

The Memory testbed is the same used in Searching for the Memory Holy Grail — Part 2 and Mushkin & Adata: 2 for the Fast-Timings Lane. All test conditions were as close as possible as those in our earlier memory reviews.

 INTEL 875P Performance Test Configuration

2 x 256Mb Adata DDR450 (SS)
2 x 512MB Adata PC4000 (DS)
2 x 512MB Corsair PC4000 (DS)
2 x 512MB Geil PC4000 (DS)
4 x 256MB Kingston PC4000 (SS)
2 x 256MB Kingston PC4000 (SS)

Motherboards: Asus P4C800-E (875) with 1.010 Release BIOS

Corsair is very clear that their PC4000 PRO is aimed at the Intel 875/865 user. They consider the better memory for an Athlon user to be their new PC3200 PRO. For that reason, performance on an Athlon nForce2 Ultra 400 was not tested.

    I wonder at which Performance Mode you have run the OC conditions (500 and 539 FSB)?

    PAT disabled, Fast or Turbo?

    These reviews should include the Twinmos Twister PC4000. This is reported to be able to do 2-2-3-6 at ddr400 at 2.75V and 2.5-3-3-6 (the only memory i have seen at 3-3 as ddr500) at ddr500 at 2.85V with the highest oc's at ddr530 at 2.5-3-3-8 at 2.85V.

    BH-5's are EOL this month...

    I'm a little on the fence here. I have a watercooled setup with an IS7/2.4c combo and I was wondering what the best 2x 512 sticks of ram would be without killing the bank. I want to do some OC'ing so I was thinking of getting the Geil 4000 plat or Buffalo 3700 (BH-5 chips). Any reason to get another kind or not to get one of the ones I mentioned?? Thanks!

    all these comments seems pretty self promoting from ocz and geil... let the readers decide and choose.

    yes, but it is Geil platinium used in the test, that doesn't use WLCSP. and still the Golden Dragon series is good althernative for reducing the heat inside the case. And don't forget that Geil's Golden series last the first ddr500 modules back in March though they didn't get available recently.

    But Geil's memory OCed pretty nicely here - at least the sample Wes had did.
  • Anonymous User - Wednesday, September 17, 2003 - link

    WLCSP is intended as a thermal solution and to date hasn't shown much promise in the enthusiast sector as it doesn't OC as well as TSOP's.

    Why is nobody but Geil using WLCSP packaging on their DIMMS? I've seen it in notebooks, but it seems to be a great option for high-speed DRAM.
