Q8300 Overclocking help wanted!

JBanks368 · 30 Dec 2012 at 21:45

I've had this since about march this year and it was second hand from a friend, could the bios need updating?

Is there an option in voltage control that says CPU vid special add? I just googled your board and if it's the one you have then that will be how you can change your volts.

Should look like this if it's the one I'm looking at.

JBanks368 · 30 Dec 2012 at 21:53

yes there is!

there's "auto" then "12.5mv. 25.0mv. 37.5mv" and so on and so on

Cool, that should add volts to your CPU. The DRAM voltage option will raise volts on your ram, but don't do anything crazy with that. I wouldn't exceed 1.9V on the ram max. More volts might stabilise the ram at 2.7ghz if that's what's holding you back. Alternatively, remove the slow stick and use the VID offset to push your CPU to 3ghz or more.

Its set default to 1.908 :')

On the CPU VID special add, it was default on 1.24 but then I selected "12.5mv" then it went down from 1.24v so I put it back to auto now its at 1.16v :S

Don't worry, just bump it up to 1.27v and see how you get on. Try removing that slow stick if it still isn't stable at 2.7ghz. If that fixes the problem keep on trucking

Its at 1.31v now with +137.5mV on the CPU VID special add....is that alright?

Yes, but it's way more than you need so will be pushing your temps up for no reason. Is put it down a notch or two.

JBanks368 · 30 Dec 2012 at 22:21

With 1.31v my temps are like 40C idle

JBanks368 · 30 Dec 2012 at 22:22

Around 65 with prime95

JBanks368 · 30 Dec 2012 at 22:30

still not letting me get past 2.7ghz

JBanks368 · 30 Dec 2012 at 22:58

Took the RAM out....3.0ghz....so far so good

JBanks368 · 30 Dec 2012 at 23:04

Runs hella slow once I've logged in

JBanks368 · 31 Dec 2012 at 00:33

All fine, 3.0ghz. Thanks a lot again! no way could I have done this without you!

I didn't have much joy with my Q8300 - highest I had it stable for was 3GHz, but it BSOD'ed after 3 minutes after boot.

Well done mate, happy to help.
