I've tried overclocking my cpu to 2.72 ghz and it was stable @ stock voltage. Then i try to set my FSB to 1333 , the computer does boot up , but the FSB rate is automatically set to [Auto] in bios after rebooting. I do have my voltage increased to 1.35 V , HT - 1.36V , DRAM - 2.1V , NB- 1.4V , SB - 1.6V,yet i've also disabled the Saving power features in configuration.However, i tried to set it back to my 2.72ghz configuration, but the bios still set the FSB back to [Auto]. The bios keeps reseting the FSB rate to [Auto]. What should i do to stop it?

CMOS has been reseted , but im still getting the same result. Bios does save Voltages and others , but the FSB and Memory MHZ will be reseted to [Auto] which is default without showing any notice. ><

i've set my voltages as u stated, but the result is still the same.

I've already updated my bios in the first place.

CPR function will reset everything including voltages and others, but apparently only the FSB is set to auto and others setting are still being saved, therefore i dont think CPR is the problem.

around 4x C

EDIT: Im curious why the voltage shown in cpu-z and other softwares is 1.240V , but my BIOS voltage is set to 1.31V , seems weird. , Does anyone know how to fix this?

It does work after the CMOS battery is taken out , but however when i tried OC few times , the AI will automatically disable the FSB option by setting it to Auto always.

May i know what voltages should i fill in below the list?

Core V:
HT V:
DRAM:
NB V:
SB V:

Added on December 26, 2008, 11:10 pmThis method works , but still having the voltage problem stated above. , im afraid the BIOS will be reseted again if i go any higher FSB , since the voltage seems stuck @ 1.280V

Alright, heres a pic of P5N-D mobo, can someone enlight me where should i do the pencil mod?

Aight, i've successfully oc'ed it to 2.92Ghz stable tested with Prime 95 but using stock cooler >< , the temp of core 1 is 50 C @ idle and others are 4x C , are the temps too high for my cpu? What is the max fan speed of stock cooler? 2700 RPM?

load @ 6x C , is there any way to max out my CPU fan speed at startup? Its running @ 1.28V @ 2.93Ghz

Core 1 temp reaches 83 C when Prime 95 is loaded, the temp seems increased drastically in heavy load . I've also remounted my cooler serveral times and re-applied the thermal grease using Tuniq-TX2, but it doesnt help at all.

what HSF do you recommend? ><

Hey , i've got a list o fewf coolers here and advices are expected ><

Foxconn Napoleon heatsink 775 LGA
Sunbeam CCF
Killer whale

What about Xigmatek S1283? it seems good but with 3 heat pipes.

Hmm , im having problem on choosing a HSF between killer whale or sunbeam >< , which one is better?
