Even if it's things where you wait like rendering videos or perhaps playing Civilization and waiting on the AI to do its turn, you won't feel anything about those 0.1ghz without a stopwatch helping you.

So guys what is the gains of overclocking uncore? I had it at 4.4GHz now i am at 3.8GHz and find no difference at all...

What programmes in day to day life actually use AVX?

x264 benefits largely from it. Programs using avx to run faster typically don't run it in anywhere near the same way as linpack or even prime do though, you don't even see a notable temperature elevation for avx2, while avx off vs avx2 in linpack can be 30c or even more

Pretty small, depends on application. I'd expect 4.7ghz core, 3.4ghz uncore to be slower than 4.6ghz core, 4.5ghz uncore maybe. If you're cinebenching on realtime priority, you should see.

Is a uncore voltage of 1.23v safe 24/7?
post #2525 of 19637
will run mine at 4.5GHz (3.8GHz uncore) 2400 10-11-11-28 mem and see the difference thumb.gif

PS: My Results (will run it at 4.2 Uncore later and see)

Interested in this as well as i'm away to start tuning the ring. What's the maximum reasonable voltage to run this at 24/7? I'm x48@1.243v and checking to see if i'm safe taking it above 1.2v to get the uncore up to x45+

Took me a lot of edging to get up from that similar 9.8 as you have to break 10.0, and admittedly a few cinebench restarts, but >10 points @4.5 on my safe 24/7 low temps low volts ht profile is sweet

Some aggressive people set like 1.3 ring, but i don't really have any idea what's safe long term, not sure if anyone does really

My CPU is now @ 4,5 GHz and a uncore of 4,3 ghz ....should i push the uncore to 4,4 (only for a better look xD) or leave it that way. 1:1 does not work...
post #2529 of 19637
Or is 4,3 GHz uncore enough? Like i said its only because 4,4 GHz uncore is closer to the core speed . so what should i do?
Core speed : 4,5 GHz

You can do whatever you want, but check out temperatures. If it increases temperatures and you end up having the same noisy PC as you'd have with lower uncore and 4.6ghz core, you should rather use the 4.6ghz and lower uncore instead of 4.5ghz and higher uncore.
