4 sticks in P5B-E

Talrinys · 30 Nov 2007 at 14:08

Hey, i just purchased another two sticks of the OCZ platinum RAM to compliment the stuff i have in already. It ran fine for a day or so, but the next day it started having problems. Now i've tried a lot of things, upped the timings to 5-5-5-15 and tried it in every slot combination possible, memory tested all 4 modules seperately and as dual channel, but it just won't work when 4 are in.

New motherboard or? Using newest bios, tried with memory remap both on and off.

Im having probs with 4x 1 gig sticks too. Seems not many people can make a motherboard that 4 sticks will work in?

Im deciding whether too send the mobo back, or just get 2x2gig sticks. Thing with mine is it kills two sticks each time, so im constantly RMA'ing

which operating system are you using? 64bit?

Not to clear in your post, you have updated to latest Bios?

Try nudging the northbridge voltage up 1.

I ran 4 sticks in my p5b deluxe no problem

Not sure if there is even a northbridge voltage control on it, that's my problem?
2 rigs i built recently have no problems with 4 sticks at all, and at higher clocks than these, with the same RAM sticks.

I have Vista 64-bit and as i said it's not a specific problem with that as 50% of the time it won't even POST with them, the rest it either crashes right before starting to load windows or BSODs immdiately after starting the load.

The BIOS is the newest one yes

Not sure how true it is, but I've heard the Northbridge has to do more work with 4 sticks vs 2 and you may therefore need to drop your FSB\overclock (and\or up NB voltage) to get 4 sticks running stable...?

Yeah that's probably true, tried dropping my OC by 80mhz which gave nothing, hmm.
Think i'll just buy a new mobo early next year for a new processor anyway, don't think this is fixable

have you tried this: reset CMOS

1)Place 1 module into dimm slot 4 (nearst the cpu)

2) Boot in to windows change Bios settings.

3) set ram voltage and timings.

Boot into windows

4) Power down

5) insert the remaining 3 modules.

See if that works
