Cinebench is fine, it's not going to raise volts beyond what you set (v11.5 at least for me).

Anyone have any idea what would cause a complete shut down then boot from windows? I'm trying to stabilize 4.7 ghz... At 2.1 vccin, 1.31 vcore. Ram is profile 1, 2400. I would think it would be getting too hot but that's not the case. Running 3 radiators here all for the cpu. Temps haven't gone over 71C full load.

I don't think that 1.31V would need 1.21 VCCIN, either you're cpu bound or something else isn't right.

You can set the uncore 300-500Mhz lower the the core clock. In your case, you could have even left it at 3.9Ghz.

That's what I thought too, but I have tried at those voltages and its no go. Set the uncore to 39 still no go.

It might be entirely possible that your chip can't do those speeds stable.

Why don't you try reducing VCore? It might be finicky with that voltage setting. Another member earlier had a problem at a slightly higher and slightly lower voltage as well.

System can restart when you're close to stable

like said i'd try less vrin for only 1.3vcore, not higher than ~1.9

I still need to get on Skype with you! Maybe sometime early next week? I found out my 4.7 wasn't as stable as I though. 1.3 did fine with a few passes of x264 but BSOD in BF3 within a few minutes. BSOD'd almost instantly with 1.31, so maybe my voltage is too high?

Thank you! Those are the answers I like to hear. I think I downloaded v15. I'll go look for the version you have.

I believe my default was 3800. I'll go back to that. No stability issue so might as well. I guess when I try for more than 4.2ghz, I'll more than likely have to increase the ring. 1.2v on the CPU core now (1.1991v technically) so yeah.... I want to at least get 4.4 outta this chip. My temps barely budged at 4.2 from stock.

Nope.

Stay on x42, drop uncore back down to x33@1.15v on override, keep core on override and instead of running XTU stress for 5 minutes before moving up a multi, run x264. Set vrin to 1.8v, core to 1.2v (what you were on), run x264 then every time it fails bump vrin up by .01v. Repeat till you get to 1.9vrin, stop, put vrin back down to 1.8v, bump core by .005v then repeat the process again until stable in x264. Keep an eye on x264 progress throughout using the run/pass/% counters. Report back.thumb.gif
