Computer won't boot with any overclock.

I have the system in my sig, but if I upt the fsb at all then xp just gives the blue screen of death and I haven't tried vista when overclocking.

I have a DFI X48 motherboard and it has lots of options in the BIOS to tweak. I've tried turning the NB voltage up (1.3V), the CPU Voltage up (1.1V) and the memory voltage up but to no avail. The memory has been tried unlinked (I never overclock my memory if I can help it) but the system still wont boot. I've tried 3.4Ghz and before that 3.6Ghx but it won't boot into xp, so I thought I'd ask you overclocking experts on here. I could get an E8400 (on a different board) to 3.6Ghz and an E2200 to 3Ghz so I'm not completely new to overclocking, I'm just a modest one. Tbh, I'll probably drop my system back to stock speeds anyway after I've found how high it'll go, I just want to find out what my CPU can do.

The VID is 1.1V by the way and it's on a stock cooler. I know stock cooling isn't the best but surely it should allow for a modest overclock, the other two CPUs mentioned above did.

Thanks,
Matt.

I have tried higher. I though 1.4V was the safe limit for a Core 2 based cpu? It still refused to boot on that at 3.4Ghz. I'll try again tonight. Thanks Vigoro, any other suggestions?

Anybody else have any ideas?

I'll see what vista does thanks sweeny, I'll also write down the voltages and check the stability on stock, thanks agedidiot. The BIOS is already fully updated. I had to do that to get it to recognise my chip. Thanks though guys. I am slightly annoyed though, you'd have thought the experienced overclockers would have flocked to this thread to help, guess not

Thanks for your help guys. Reset BIOS to Optimized defaults and now booted at 3.4Ghz, with a bit of tweaking all will hopefully be well for higher speeds. Only on stock cooling at the moment (I couldn't get my Zalman fitted) but hopefully will clock higher (4Ghz with a Q9650?) with a better cooler.

Thanks again.
Matt

Well, after successfully getting to 3.4Ghz, I restarted and went for 3.6Ghz. The computer wouldn't have it and both Vista and xp refused to boot

Then it wouldn't boot to 3.4Ghz again. I will leave memtest running overnight to see if the problem is my memory, but apart from that I have no ideas.
