OCZ 2GB PC4000 GOLD XTC testing

[perry_78]

This should have been done AGES ago...

These sticks came directly from OCZ, are Samsung UCCC chips, however my CPU mem controller appears to have trouble running over 275mhz 1:1 with a 10x multi without a compromise in stability. I've tried many max async/read pream and drive strengths, but in vain Not sure what weekcode, bigtoe told me that I shouldn't venture into the lands of heatspreader removal unless I like ripped off chips.

So far I have no results at stock speeds, to be honest I never even ran these stock All vdimm values are BIOS set values! Real values are a little off, the sweet spot seems to be exactly 2.8vdimm (2.7v + 0.3v bios set).

ddr540 3-4-4-8 2.6vdimm SUPER PI 32M
ddr540 3-4-4-8 2.6vdimm SANDRA MEMORY BENCHMARK
ddr540 3-4-4-8 2.6vdimm SANDRA MEMORY + CACHE BENCHMARK

Bumped the vdimm a bit, raised TRAS and lowered multi for stability's sake, this 3700+ is nothing like the old opteron

ddr540 3-4-4-10 2.7vdimm SP2004
ddr540 3-4-4-10 2.7vdimm SUPER PI 32M

Next step was of course ddr550. This time another voltage bump with+0.3v, which I found was the optimal voltage for this particular kit, and TRAS to 12. For some reason, TRAS helped a lot. I'm assuming this is because I screwed some other setting I am not aware of, as never has TRAS had such an impact before from my experience. Any advice will be greatly appreciated!

ddr550 3-4-4-10 2.7 +0.3vdimm SP2004 running

Another TRAS bump. This was easily 3d stable, and I think I can get this to run SP32M as well once I figure this controller out. I need to re-run 3d though, only have a 3-4-4-12 275 screenie.

ddr560 3-4-4-12 2.7vdimm +0.3v SUPER PI 1M
ddr570 3-4-4-12 2.7vdimm +0.3v SUPER PI 1M

addition meanwhile:

ddr550 3-4-4-12 2.7 +0.3vdimm 3DMARK06

-> currently wr in x600xt, first attempt

I hope to get more results at DDR400, DDR500, 2.5-3-3-6 etc. later in the near future! 3dMark may be an option, however most of my gfx's are currently busted

btw, if you want to host these images internally, please do! I hate imageshack.

[edit] going for ddr400 later, CAS 2 is a no go.
