Venice, DFI NF4, and Plat Rev2's will NOT overclock!

[apu673]

Ok I previously had a pair of 2x512mb sticks of OCZ EL Plat Rev2's (v1.0 TCCD), and they would not overclock to anything no matter what I did. They weren't even prime stable past 4 hours at stock, so I had them RMA'ed. I tried all types of advice on timings and voltages on these sticks. So I just got back a new pair of v1.1 TCC5, no big deal. They were prime stable for 2 hours, so I thought finally some good sticks, and i've been running them at 250mhz with the below settings, and at 2.6-3.0vdimm, it fails within 10 min. What gives? Could it be a corrupted install of windows, or a bad graphics card (new x800xl that doesn't run games without artifacts but i dont know?). I'm ganna continue to run these sticks at stock settings to see how long it goes in prime, maybe these sticks are fine but it's something else.

try and play with TREF refresh period as that setting alone can make or break stability on NF4. Look around for other people wiht similar chips and see what they are using. I would love to help you more but TCC based chips TREF will be much different than my BH based TREF. Good luck.

I myself have a DFI NF4 Ultra-D, Venice 3000+ 0519 LBBLE, and 2*512 OCZ El Rev 2 and the 510-2 bios off dfi-street.com - Maybe you should try that one?

Have you ever thought that, it might be your Venice, that gave you all the headache.

I have the DFI Ultra-D, 510-3Fix bios, 0517EPMW Venice, and the OCZ Platinum Rev. 2 (TCCD chips). doing 9x300 at Vcore 1.39V, DDR600 at Vdimm 2.7V all right.

Now I switched to my backup CPU, a 3000+ Winchester, running now at 9x280, Vcore 1.29V, DDR560 at Vdimm 2.51V, not for benchmarking, for my daily use.
