In practice, despite setting it on 6x multiplier and trying to OC via FSB in the 400's, the bios ALWAYS falls back to setting 7x multiplier and FSB in the 300's (i currently am running at too modest and very disappointing (7x309)=2.163 which barely pushes 15% of stock 1.86) regardless that what it POSTS totally contradicts what it actually runs at.
That is WEAK. If it's not going to let me OC the FSB and set my multiplier at 7x it should at least TELL me that when it POSTS on boot, rather than say i'm OC'ing at 6x before I get the wakeup call from my software needing to tell me otherwise.
Anyway, seems like everyone here did the smart thing and at least picked up the E6700 QNX unlocked, which I should have thought more seriously of doing. But seeing that the E6300 has monster overclocking potential on other mobos, i really did expect more coming from GA's N680 ethusiast offing.
Firstly i gotta i'll get to Smitty in a minute ok LOL. 2nd all this is at your own risk ie. Disclaimer etc..
Hit CNTL F1 when booted into bios.
Ok lets party. Firstly in the ADVANCED section of bios setup make sure you have No Execute Memory Protect=Disabled, CPU Enhanced Hlt=Disabled, CPU EIST=Disabled, Virtualisation Tech=Disabled, so all you have in that little section that is enabled is the CPU Thermal Monitor(TM2).
The reason behind this is they will throttle your O/C's once in windows etc. If you to farr with your O/C you still cant boot and have too reset so their is still a bit of a fail safe there.
Ydef i dont know what ram you have but this is what i suggest (if you dont know where these settings are let me/us know). Set the Multi to 7.
SLI Ready Memory=Disabled
FSB Memory Ratio=Unlinked (to start with)
CPU Host Freq=350fsb (this is to start with ok)
Memory Freq=800(not know what RAM you have makes this hard, even Generic is doing 900@4-4-4-12 easily in most cases on stock volts)
Now the 3 PCIE options, set them all to 100 ok, as with some O/C teh Auto function sets some realy stupid numbers and could corrupt your O/S install.
Change your memory timings to the above as well 4-4-4-12(you could do better)
As fot Voltages just stick with standard 1.3v(no warranty voiding there) and on the DDR volts change it to .200.
Boot up run a few wPrime runs, with 2 cores selected or Prime 95 small fft's for 10mins, this will dtermine if it's stable and keep an eye om temps (suggest you use Core Temp .95). If all is good keep bumping the FSB by 10 each time till you hit a ceiling. Then if you have EXCEPTIONAL cooling chuck a couple of more volts at it as there is some serious vdroop on these boards, ie. Bios is 1.3v under load real is about 1.23odd.
Have fun and let us know ok.
