Does Bios affects OC capabilities?

Does your MOBO bios affect your OC capabilities? Just a ??? that hits me, the fact that I have a 3.4C but its highest OC is 3.8ghz(stable) with all the right settings which i did(advise in this forum) my effort was futile. I was also thinking of possibilities that my memory is holding me back, i just dont want to give up on this CPU, so i was thinking maybe its the bios, is it?

Ummm.... 3.7-3.8Ghz is a great OC.

Especially considering the fastest P4 chip Intel is going to release is a 3.8Ghz, you should consider yourself lucky. They cancelled the 4Ghz chip for a reason!! (too hard to get the chips to reach that high)

Now if you had a vapochill, I'd say shoot for 4Ghz. But watercooling doesnt really help that much with P4's (at least compared to highend air)

BIOS's can affect your OC. Some BIOS's are more aggressive than others and can change your max OC slightly. The main thing that I've seen holding people back with P4's is them trying to use 1:1 memory ratio, and not even trying the slower memory ratios, and/or trying to use too tight of timings (or PAT/GAT settings)
 
ived tried loosening my memory 5:4/3-4-4-8 and newer bios, i was thinking of maybe the older bios would work coz 1019 bios i think is for prescott support, do you think that would work?

I doubt the BIOS will make that much of a difference, like I said it can SLIGHTLY affect your max OC. But it usually has more to do with the way the mobo works with the ram, than the processor. Some BIOS's are more aggressive with the ram than others.

But at 3.7-3.8 Ghz you should consider your OC a good one and be happy.
 
do you think getting a higher RAM would make a difference and would push my CPU to a higher OC? or i just hit the limit of my CPU? its very frustrating coz i thought 3.4C are good to OC and 4.0ghz would be easy to achieve.

You...already...have...a...good...overclock. The odds are very good that you've hit the limit of your particular CPU.
 
What are your voltage settings for your 3.4C? What are your ram settings?
 
vcore is 1.55v and RAM setting are 320mhz/5:4/3-4-4-8/2.75v, spread spectrum disabled

You might try increasing VCore to get a higher OC, however your ram is fine at those settings. At 320MHz (PC2700 speeds) it's not going over it's intended 400MHz clock. So you are fine there.

Be carefull not to go to 1.7v or over otherwise you can cause SNDS. Which is bad. Just in case you didn't know, your processor won't live long on air cooling with that kind of voltage going through it.
 
I think my CPU just reach its highest OC:mad: , increasing voltage didnt help, might as well get a pressy no luck with this one. thanks anyway for the help ;)
 
BTW, what were your temps ? idle / load ?

What voltage did you try? 1.6v ?

Thats the max I do on air cooling.
