Nice. Is your UD4H C2 revision?

I managed to go down to 1.212V on 4.4ghz. That seems like a nice bargain. It can hit 90C in prime, but good temps in normal use (gaming, video converting)
Very similar to my 4770k. Im running it at 4.4Ghz with 1.205v, 12 hours Prime95 stable. Our chips are probably still good ones, I read that many people need 1.250-1.300v for 4.4Ghz.
I'm using a custom water loop and the maximum temp spikes in Prime still hit 77°C but normal Prime load is around 65°C max and FFmpeg video encoding (uses AVX) is at only 55-56°C which im very comfortable with.
The temps look good, and its the safe side of volts, but its a lot for 4500mhz
I can boot 4.6 @ 1.25v and 4.7 @ 1.27v, so probably could get 4.7 stable around 1.3v. Seems like it would benefit from delidding, might do that in the future.

Are you on F7? Good results btw.
I've never actually tested above 4.5, so I'm wondering if the voltage curve steepens only after 4.5 for you.
Anyone using MSI Z87-G45 upgrade to 1.50 BIOS?
Even at 4.4 @ 1.2v, about 15 minutes in, the 27.9 P95 tests change my temps SHOOT up, like from ~65C to over 90C.Nope, Google brought me that one. I'll run it tonight. Stable in bf4 so far too.
Edit - thanks - those definitely tax my cpu a little more. 4.4 is better.
Well, I decided for the first time since owning a computer to try to overclock my CPU. I set the multiplier to 46 and voltage to 1.200. It failed to boot into the OS Layer. So I set the voltage to 1.25 and it boots to desktop. Next I run wPrime 32M and it passes. The temps looked good. 1024M is ran and it still passes. The temps were 67, 67, 66, 61. I'm using a Hyper EVO+ 212 push configuration.

What are my odds of getting to 4.2GHz with a 4770K? Not running 100% multi-thread load 24/7, just gaming, regular apps, sometimes 100% single thread compression for an overnight backup, etc.
