cant get anything out of 2.8C

[Twigss]

Heres my rig
P4 2.8C
P4800-E Deluxe
4 x 256 corsair cmx3200c2 @ 2-3-3-6
9800 pro
500 watt enermax psu

when i try to increase my fsb by even as little as 5, i get a bios error about overclocking error :bang head i think its the memory that i put in because it was a pretty good ocer before i put in the 3rd and 4th stick...

I've heard (but am not positive) that having four DIMMS is detrimental to performance...

[x3lda]

definitely the memory, for best overclocking, picking one memory module to use is the best. more memory models hinder your OC since the worst module in the 4 will cause a crash even though other can go higher. Also, you have to use 2T when you have 4DIMMS which decreases performance significantly.

damn... well i changed the ratio to 5:4 and now im running 3.2 stable(from what i can see so far...) 30C idle and 40C load....

[Twigss]

damn... well after some more testing, its definately the memory... i think ill sell all of it and buy me some new memory... time to start hunting the cyber deals...

Yeah, 4 sticks will kill the OC most times. 5:4 mode is the way to go for a lot of 2.8c's. If you get ram get either BH5 or Samsung TCCD 512MB sticks and it should allow you to use more of your cpu.

I have the same ram as you 4xCMX256a-3200C2, I have 2x v4.1 and 2xv6.1. I was able to obtain 230FSB 1:1--- 2.5-4-3-7 stable for 24+ hrs of 2xPrime 95 and MemTest86. But let me tell you, I went through so many different configurations, it has taken me 2 months to achieve 230 FSB 1:1.

Edit: I forgot to tell you what I did to fix it...lol, my memory is going, no pun intended.

Anyway, I put the ram in the slots in the order I wanted them and then I ran Sandra Burn In Wizard memory benchmark 12hrs a day for a week. Worked magic.
