Problem overclocking on P5B Deluxe.

Messiah Khan · 1 Apr 2007 at 15:38

Hello all,

I seem to be having trouble overclocking on my P5B deluxe. I did have a E6400 on a P5B deluxe, but then due to a stupid m,istake, the mobo blew, so I had to get a replacement. On the first board, I could get up to about 505FSB, and the CPU up to about 3.8Ghz. On thios replacement board however, I can't do anything! As soon as I try and change a setting in the Bios and reboot, it simply doesn't post. I can't even overclock by 1mhz. Im sure ive set everything how I should. Any suggestions? :confused:

Well everything runs perfectly fine at stock, its just when I try and set things to manual in the Bios that it refuses to post. So im assuming its not the other components. I also hope its not a duff mobo, as its now smothered in di-electric grease etc.

what bios?

The one the board came with was something like 0850, but now ive updated it to 0910, which is what my last board was using.

Any joy?

Nope. I did that a while ago, one of the first things I tested. Still exactly the same.

Right, ive done a bit of playing around today. Ive managed to set everything ready for overclocking, i ive disabled vanderpool technology, disabled speedstap, sat Ram to manual, etc etc. And it posts. So ive started to slowly up the FSB, and it works for a while... up to about 340FSB. Then it simply refuses to post after that. Its not the strap blackhole coming into play either, as it doesn't post on 401, 420, 450 etc. One thing ive nboticed as well, is that when I set, say 420FSB, it doesn't actually reboot. The screen goes black as if its going to reboot, but the power stays on. So then i have to switch it off and on, which obviusly resets the overclock. :confused:

Yeah, same CPU. I hope its not damaged. I doubt it is though tbh, as I wouldn't expect the CPU to work at all, or very unstably if the burnout had damaged it. Im annoyed as well, as I did have it up to 3.7Ghz Orthos stable, or 3.8Ghz windows stable. Now im on 2.6Ghz

Not really worth having phase for that is it.

Looks that way. But im no RMAing it now that its covered in Di-electric grease and buried under Phase and watercooling kit.

Im back! Hope you all didn't miss me too much.

What are you going to do?

surely not run it at 2.6ghz

By the way I'll need you tomo night

Not sure tbh. I want to finish the rig first(sidepanel etc,) then I'll see. Don't really want ot spend more money though.

Have you got a m8 who will lend you a cpu to test?

Unfortunately not. I don't really know many overclockery types, and no one I know have a C2D. But as I say, I can't see the clockability(a new word?) of a chip being diminished by a fried mobo. If the mobo had affected the chip, I would imagine it would completely cook it.
