It seems I only have an option on PLL for 1.55 or 1.65, I tried to key in 1.59 but it just reverted to 1.55...

I would really like to try and get to 4.25 (500 x8.5) if anyone has any tips, I am listening...
My temps in Prime and occt never even break 55c, IBT they get a bit warm (65 - 68), but I am ok with that.
For my 1150. Almost to the brink. I was at 2.02V (1.8 stock). Then don't worry about ich volts when overclocking. But for mch I had 1.3v. What are your NB volts (mch) for 4ghz?

For 500fsb I would do atleast 1.34 on NB and 1.34 or 1.36 for the cpu. And termination voltagae i would would do 1.32.

there in the advanced mem timings all the way at the bottom gotta do them for both channels.
i was messing with them becuase it seems out of the blue my 100% rock soild oc would go unstable if i left my pc idle for lets say 12 hours

so i tuned the dram skews a little and so far so good its good stuff you can also lower some vcore

for 1:1 i was using + 400PS i tested 100 - 700 all were fail expect 400ps give it a try

hmm...lower some ram voltage. Now thats promising. Im gonna need it to push these value ram sticks. haha.


http://www.newegg.com/Product/Produc...-166-_-Product how are these ram sticks? I may have clearance issues with the pi's and these seemed to be higher rated. So how are these?

OK, so I bumped my Vterm to 1.38, set CPU drive to 900mv, no dice, still the same issues, crashes out after a couple hours of blending.

I don't think it's my vcore voltage cause that will probably give problems earlier on (like when running 20 intelburntest runs or something). You know the deal, one time it's stable, suddenly the wind-direction changes and there she goes

Anyways, what do you guys think, give cpu term and pll another bump?

Oh and btw, when something like burntest fails or prime it's always with a system lockup or a bluescreen. So no rounding errors or errors in burntest.
I bumped my vcore to 1.40 in bios, thats 1.4240 in windows, just to see if that was the issue and let it run overnight but it crashed. So it has to be something else. I haven't touched my RAM yet to feel if it's running hot I'ld be surprised if it was that though, it used to run at the current timings / 1080mhz @ 2.1 volt.

at Koji. How can you have the Vcore higher in windows? Thats impossible. and I would lower your term. Its a bit too close to the vcore for 4ghz

Guess that's something with LLC, it rounds up to 1.408;



As for the Vterm, it used to be on 1.34, bumped it to 1.38 yesterday but there seems to be no difference in stability, that screenshot is with Vterm @ 1.34.
