Yep, maximum or high and for 10 iterations usually.Are you running IBT on maximum? Usually it finds issues within the first 5 loops.
The problem is it's very suspicious that I can't even avoid in-game crashes at 3.2 GHz with generous voltages, yet it can pass IBT at 4-4.4 GHz with reasonable voltages quite happily.That's the thing about overclocking, you can't ever be sure of stability even with the best stress test apps. They are usually good enough t get you started, a rough cut.
but the real world apps you run are the only true way to find out if your OC is stable enough for your needs. This is what I call rock solid. Not only passes stability test I ran but also runs 24/7 without crashing. Still though, Its hard to say any PC that is overclocked is 100% stable and 100% fine. There always could be that random app or random crash. My i7 920 was extremely stable for me all the way up to 4.2ghz. It would run everything I would throw at it, no problem. But I remember at least 2 times I blue screened running my daily driver 3.8ghz overclock. This was 2 blue screens years apart. Both times I rebooted and ran a ton of stability test and games that should crash the computer if my overclock had become unstable, I ran everything I had but it seemed 100% fine. I just chalked it up as one of those things, but you just have to know that there is always that risk when overclocking.
But heck, in my case those random blue screens may not have had anything to do with my OC at all. It just might have been one if those things....
I've tried 180x20 at VCore = 1.35 V and VTT = 1.35 V, still got crashes. Already ran memtest, passed no problems. Uncore speed is Auto but I've also tried manually choosing the option that is double the DRAM speed to no avail.Anyway, I would run make sure the ram and IMC was stable. Run memtest overnight with your overclocks that crashed. Also, what vtt voltage are you running? How bout the uncore speed?
You could try bumping up the vtt just for extra stability. Perhaps try bumping up some other voltages one at a time, like IOH core or PLLs.
One thing I haven't played with is PLL voltage but I've never needed to touch that in the past. Is it worth trying to push that up to maybe 1.84 V even for a mild overclock? I'm sure I've heard at some point that increasing PLL voltage can actually harm stability...
