6850k Overclocking 4Ghz BSOD
6850k Overclocking 4Ghz BSOD
Hello,
I just "upgraded" from a 5820k to a 6850k processor. The 5820k overclocked easily from 3.3 Ghz to 4.0 Ghz easily with just my little H90. But now I'm trying to reach 4.0 Ghz with the 6850k and I'm getting a BSOD after 4 or 5 hours of the computer running (it was idling at the time).
The settings for my attempt at 4 Ghz (using an x99 sabertooth): multiplier of 40, and voltage set to "auto." Memory is set to XMP 2 2400, it's 2133 corsair vengeance.
Prime95 ran for 25 minutes and checked out "okay." But like I said, doing next to nothing it BSODed on me.
I've got other things to consider however but such as; I just formatted all my hard drives and reinstalled everything, drivers may be the culprit to the BSOD, or some other issue. So right now I'm running it just to see if it will stay up and for how long, (at default stock settings, 3.6 and xmp off.)
UPDATE:
I've run Prime95 with no overclocking, all factory settings, no problems whatsoever and the machines been up for a day now without a BSOD. So it looks like I'm just having trouble overclocking this processor.
It’s probably best to increase the voltage slightly. Many users rely on overriding and static voltage during OC, though some opt for offset voltage instead. Auto voltage settings can be tricky.
However, a 4.0 should work fine with minimal adjustment. Begin with auto voltage, then fix your input voltage to a fixed value of 1.9. Adjust LLC to high or the maximum level you have. On an Asus board, this might add a bit more voltage to your vcore when under load, which could be useful. Check if this alone improves performance.
It seems you're likely looking for a bit more voltage. Many people prefer overriding and using a static voltage when OC'ing, though some like offset voltage. Auto voltage might cause issues. Still, 4.0 should work fine with minimal adjustment. Start with auto voltage, set input voltage to fixed at 1.9, and consider setting LLC to high or level 1. An Asus board might add extra voltage under load, which could help. Check if that improves stability. Regarding LLC or changing input voltage, I'm going to adjust the core voltage to 1.2 and the multiplier to 40 as suggested. I'll look into it further. My water cooler can't go much higher than 4 Ghz—it wouldn't handle it. Edit: I'm not sure enough about altering input voltage to feel confident doing that.
