Ok am currently running 'the prime test' with these settings:

multi:45
offset +0.005v
turbo +0.004v
LLC: level 4
Disabled all C states except C1E
PLL Overvoltage disabled

About 20 minutes in, so far so good. Voltage at idle drops to around 0.984v to 1.000v. Under load, min 1.312v to max 1.336v. On average it appears to be 1.320v though. I tried the same settings but with LLC 3, however it was bumping up the load voltage to around 1.360v, and I know this chip doesn't need that much for a 45 multi. Not sure why LLC is so 'aggressive' even at level 3.



Given how low the turbo and offset is, it seems like the LLC is doing most of the 'overclocking'.

good work try lower the voltage as much as you can but keeping you OC stable.

Thanks, In my bios, it won't let me select lower than +0.004 turbo or +0.005v offset.

Update: Passed 1 hour prime blend (custom as in OP) no issues.

Now i've only changed the multi to 46, nothing else changed, and so far it's passing prime (fingers crossed) at average 1.320v under load.

Best I could do in IBT with 20 passes and custom stress level to 6500MB.

What I don't get is, that I'm only on +0.004 turbo voltage at 4.4GHz but at 4.5GHz, that would not happen. I needed around 0.041+ to be stable. Temps are still the same, but my guess is either the paste in the CPU was applied really badly or dried out, or my room is super hot. I'm not worry about temps now though. Highest core was 85C, but I'll leave it because it surely won't get that high in gaming. I'll probably go watercooling soon as well.

To decrease your voltage you need to switch to a negative offset. There isn't a 0.000 offset, the middle is a -0.005/+0.005. Do you have all settings the same as the first page?

I have the same settings. I just upped the cpu multi by one, and it's about 10 mins away from passing 1 hour prime95.

If it's stable, i'll probably just be happy to keep 4.6GHz at 1.320v. The one game I like to play most, Microsoft flight simulator, is very much cpu limited anyway.

this is what i came up with my 3770k same vcore it does run 4.5 and 4.6 with the same temp smile.gif i seatle it at 4.6 when i bench i can go higher if i want to.

ps: @ 1.228v

I basically kept an eye on cpu-z the entire hour, it was going between 1.312v and 1.328v, settling on 1.320v most of the time. I don't think I should be greedy and try to use negative offsets, that's already a decent vcore for that speed. thumb.gif

you got it. the HW shows you that CPU had spiked the voltage to 1.344 but it does uses the 1.312 all the time smile.gif now you have better temp's thumb.gif

It only spiked that high once, the moment i started prime95. Much happier with this offset way than fixed. I used to fold, so I didn't care to much to learn about offset as the cpu was under load 24/7.
