So I've been fixed overclocking this delidded 3770k on a MSI Z77A-G45 motherboard and tweaking with the settings, but I was hoping that I could get some advice. I went from factory settings straight to 4.5 @ 1.2 v and stressed it with Prime for 9 hours without any errors, the hottest core consistently averaged around 53 C in 83-84 degree ambient temps. The problem was that I couldn't overclock past 4.5 without getting barraged with assorted BSOD's after booting into Windows at voltages all the way up to 1.38, let alone use Prime. I figured even if I could stabilize it at 1.4 that an extra 100 mhz isn't worth a 17% increase in voltage being applied to the CPU, so I just accepted that 4.5 was this chip's wall.
Well, I guess my motherboard's bios wasn't exactly up to date despite having just updated it with Live Update 6 the day before, and after checking the settings in the bios for any options that weren't previously included after the flash had set the board to default I noticed that unlike before I could modify the long and short duration power limits with Turbo Boost disabled. I then set the limit to 200w for both, set the CPU to 4.6, CPU core voltage to 1.20 and I was actually able to boot into Windows without BSOD's and could run Prime, so naturally I upped my CPU to 4.8 at 1.35, got a BSOD and had to reset to default. It was then that I noticed that being able to modify the power limits with Boost disabled was a fluke and that I was back to square one at 4.5 without being able to modify these settings, so I started overclocking the CPU multiplier with Boost enabled while leaving the max boost multipliers at 3.9, and could get past that 4.5 wall again.
Does anything seem off about this to anyone? Can setting my bios like this conflict with other settings or even give me false readings at clock speed and voltage in CPUID or HWINFO64? I noticed that in both of these programs that the voltage readings are usually about .03 off from what I have my max voltage set to during Prime, e.g. 1.22 instead of 1.25. My performance monitor in the task manager is also reading like 6 GHZ speeds for 4.6 GHZ max speeds during Prime. Should the any of these discrepancies, and probably not so much the latter, be considered accurate or an issue? If so, I can certainly see why even now I'm experiencing some difficulties stabilizing at 4.7, and I don't think I'm going to be able to stabilize 4.8 unless I'm at 1.40 or above, which is something I don't really want to do. I mean, I'm good with even 4.5 but it'd be nice to get a stable overclock at 4.7 with a reasonable voltage.
These are my settings:
Oh, and the multiplier and core voltage are at auto because I'm at default with these two right now trying to figure this out, all the other settings are what I've been using. If it matters, I'm running Windows 8.1 with a 750W PSU, and since I haven't got a dedicated GPU yet I'm using the integrated graphics at stock on my processor.
