Alright here it goes, I have a MSI 915P combo with a P4 3.4ghz proc 550 model with 1gb of some samsung memory pc3200(crap i think). This is all watercooled and i'm running CPU temps of 26-28C and sys temps of 30-32C. I can't get this to overclock at all. I've tried 215 FSB and my comp won't even post. Is there something seriously wrong here. I'm mean i've oc'd at least 25 comps and i've never seen anything like this. I mean I know the only real downside to this rig is the memory but I should be able to at least get 3.6, 3.75, or even higher out of this right? I would grealty apprciate any suggestions you guys might have.

I'm also going to order some new memory for this as well... I was thinking either 667 or 800 anyone have any good experiences with any particular modules. I was thinking either Corsair XMS or Crucial Ballistiz

Have you tried a devider on the RAM? I think that is your problem.

another thing i noticed I have a thermaltake pure power 680w and it says my vcore is at 1.24 when i have it set to 1.3265 could this also be a problem?

F-Disk

most likley yes sounds like a motherboard problem to me

AwDxTc

what i don't understand is, is that in the bios it states 1.3625 and in cpuz it shows 1.25. I'm not sure what the hell is going on?

after playing with some settings i got it to post @215fsb but i can't seem to go any higher, i upped my vcore, loosened latenices, i've tried evrything and nothing seems to work?

CPU-Z isn't bugfree . It says my VCore is at 2.20V, I could only wish my core would run 2.20V @ 33*C

Trust the BIOS instead of CPU-Z , CPU-Z is only a nice indicator for some things.

Agreed CPU-Z is only accurate on certain mobos to a certain extenct. Bios is usually more trustworthy

Memory is the immediate issue I can see, your forcing it to run at 430MHz when its only built to run at 400MHz. If its poor memory then it will cut out around there, which is what it seems to be doing. I would recommend increasing (if possible) the DRAM voltage to see if that will let the memory operate at a higher frequency than 430MHz.

Also did you lock the PCI-E (or AGP) and PCI locks on your board at 100.0MHz/33.3MHz (66.6MHz for AGP) as they can cause issues with the system and problems with stablability.

Investing in some new memory would be an excellent idea though. Try and keep the memory in a 1:1 ratio with the FSB however, but if it really won't do it then follow SoaDMTGguy's excellent advise and set a divider.

As already mentioned in previous posts CPU-Z can not always detect the correct voltages, it does happen to detect the correct values on my system though, so it can work
Now the vcore in the BIOS will be correct, however, when your CPU is running at 100% the vcore will be a little different than what you see in the BIOS, but it will still be around the same level as what it was set at.
