BSOD when Overclocking

[ZCommander]

Greetings all,

I'm not new to overclocking but new to overclocking a core i7
Recently I've been trying to overclock my Ci7 920, My goal was a 3.8GHz with my ci7 batch 3841A, but seems that I fail all the time, the last attempt made me complete 11 hours of Prime95 but on the 12th hour it gave me BSOD.

here are my settings at that attempt :

Re: BSOD when Overclocking

ooops, forgot to stat. the specs :

EX58-Extreme
Ci7 920
OCZ intel extreme 3x2GB DDR3 1600
4780X2
Xfi-Fitality
Cooler Master V8
2x120mm Thermaltake Cyclo fans
1x120mm Zalman fan
Thermaltake Spedo case
Thermaltake Toughpower 1200 (going to change it next month seems to be the cause of the no boot problem)

At 3.8 with the above BIOS setting the maximum Temp. is 78 after 11 hours of prime95 but most of the time it will be at 68-71 c.

Any one !

Re: BSOD when Overclocking

BTW what is its stock mhz.
has it run perfect that way at stock?

[ZCommander]

Re: BSOD when Overclocking

Ya it runs fine at stock speed.

[Tyreman]

Re: BSOD when Overclocking

Ya it runs fine at stock speed.

so its 2.66mhz quad?
3.8 is pretty high oc for that?

[ZCommander]

Re: BSOD when Overclocking

Too many People reach 3.8 with those 920.

Re: BSOD when Overclocking

I don't have the new system like yours
I imagine ram timing need be loose for one thing.
Its on turbo? is there a lower setting?

[ZCommander]

Re: BSOD when Overclocking

RAM timing when set to auto is very loose.

[Tyreman]

Re: BSOD when Overclocking

RAM timing when set to auto is very loose.

But is there a looser setting than turbo?
like say standard.

Re: BSOD when Overclocking

There is but with turbo it runs at CL10 which is higher than the standard CL8 that is stated in the OCZ sticker and site.
