With x264 coming to strong conclusion that for 4,6 Ghz my cpu wants more Vrin and Vcore. With Vring I am not sure.
Went up from 1,86 and 1,26 to 1,92 vrin and 1,3 vcore. Run 2 80 % best result so far.
Also noted that after one day, test results can be different with same settings.

What kind of bsod (124, 101 or 9c) did you get ?

Always 101 arrrgghh.....

With 1,235 I can boot 4,6.

Yep L313B428
, its prime 27.9 stable with 1.24vcore 12 hours, but for 28.1 i Need 1.26vcore....so i set it to this voltage and now the cpu is rock solid....just runs everything gaming,x264, prime95,linpack and so on. but i tried 4,7 ghz but there Begins the voltage wall ...i Need 1.35 vcore to run prime95 28.1 so.....i m happy with the 4,6Ghz

Quick question to you guys that might be a bit more familiar. I just put together my new build last week, and I've started tinkering with my clocks now that I got all my water cooling gear in. I have one core that's on average usually around 8-10 degrees cooler under load than the rest seems to be regardless of clock speed. The other 3 are usually within around 3 degrees of each other. Idle they all hover around the same temps. Obviously there will be variances, but that one core just seems odd to me. I've been pretty out of the loop with the recent chips (my last was a Core 2 Quad) so this may not be completely out of the ordinary.

Chip is delidded, with Liquid Pro applied to it. I was pretty careful to evenly apply pressure with the CPU block. Everything seems to be working fine. Just curious if I should worry much about it right now.

I thought I would get 4,6 with 1,29 fully stable. But now, I am not even sure if I will get 4,6 with 1,3 stable.
For 4,5 I would need 1,24, Prime 27.9 and x264 stable.
So 4,7 will probably need between 1,37-1,4 if ever possible....mad.gif Voltage wall

My core 3 was cooler on my 4670k, usually about 5-7C difference at all times, especially when benchmarking. My was not delidded. Maybe delidding increase the difference?

I guess I should have added that the difference is only under load. Idle they are all within normal variances.

its up to u just watch the temps....and there is no Performance boost from 4,5 to 4,6 , its only for a better look so...for me is 1,3v max. for 24/7 but you could go further but then i think its not worth the 100mhz.....

edit:: i see you have ddr3 1866mhz for me the ram Speed has a big effect i run 12hours stable with 1600mhz but with 1866 mhz Crash after 2 hours

Has something to do with the layout of chip. Core 0 is the hottest most of the time. Is normal. You could try lapping the Heatspreader, maybe it will bring the cores temps closer together.

Core 2 for me, normally +5-7 deg under load. I'm putting it down to the IHS not being lapped which i'll do when i replace the TIM.
