it disables metro ui and everything related to metro permanently without affecting anything else...

WOW! just got it working, very nice. So this setup shall yield better performance than 7?

any performance gain win8 has will remain that just reverts some of UI back to win7 style, should be better performing if win8 is...

add a fan to the northbridge (they run hot)

windows 8 is faster than windows 7. Not by much, but a tad.

There are more than one voltage that effects the FX cpus other than just vcore. Are you monitoring voltage drop? What are your other voltages? Yours temps are kinda high for a h100 push pull. I don't go above 50c with my antec 920 push pull (granted its not exactly stock, i drained the fluid and put in distilled and water wetter 2-3 c drop in full load temps)

Fx's don't like things above 50c. Its weird i know, but the lower your temp is (closer to ambient) the better overclocking you can do, with LESS voltage.

Do you have LLC on that board? it makes a world off difference. i have 2-8150's and a 8120 and all are 5.0Ghz or better with LLC. they top out at 4.7-4.8 without. (cooling considered of course)

Funny thing I found on my CHV board. I have always read to set the HT to default 2600. For some reason or another I was having trouble getting past 4.3 GHz. I don't know why I did it but I lowered HT to 2400. Instant stability at 4.3GHz with 1.35 vcore. Moved to 4.4 GHz but wasn't working so I tried it again and lowered HT to 2200. Full stability. Finally finished stability for 4.5GHz at HT 2000. vcore is at 1.39v at full load with max core temps at 51*C. I never had better performance in bench marks so makes me wonder what I lose while lowering HT. The only reason I don't go higher than 4.5 GHz is my pc shuts down automatically when stress testing and I think 4.5 is a nice round number. With core temps at 51*C I can only assume that my psu is too taxed at that lvl cause the only way I can restart is by resetting the psu and unplugging and plugging it back in. Anyone know what I will be missing without the higher HT? Can anyone confirm why my psu shuts down? Currently folding along at 4.5GHz with 50*C max core temps.

Well my case is opposite...I've FX 8120, early one, somewhere from January batch I guess and my CPU refuse any sort of multiplier oveclocking...but...at 16*250 with HT at 2500 and my NB 2500 it works miracles...stable as rock...

Also if I am about to run this one at 4.5GHz...simple run it at 18*250 with app.1.41V and I'm fine...
Now this is the question, why this CPU refuse any multi only OC....I would like to run it at 20-23*200MHz with HT 2600 and NB 2600, but so far no luck...any clues?

this is what I got now...

fsb 2200 ht 2600 multi 23
I already tried with ht 2200 no change at all....
the actual voltage because of LLC is 1.45-1.46-1.47

I can't go any further because of the temps.... I have 57-58c running prime done 5h test its fully stable... ambient temp about 27-30c I could run the AC but no point OC-ing with the AC on... I need stable oc not as high as I can go...
the air the fans are blasting from the rad is kinda hot... but rad is cold to the touch...

this might help you guys.

I can go to up to 5.2ghz on my 8120 across 8 cores. Though i disable one core in the 4th module and use the 7th core in single threaded applications. Nice 15-20% boost doing it this way, via core affinity

took me awhile to find its upper limit though a various number of settings. 5ghz was relatively easy at 1.45 vcore and some boosts to other voltages like northbridge, fsb, hyper transport, etc....

5.1-5.2ghz was a nightmare of trying different settings. Would run just fine but just needed to find that stable combination. I also had to run at 1.55 vcore as it would drop to 1.5 under load. My fans scream as they try and remove the hot air from the radiator. Winter time its bearable as ambient temps are lower and fan speeds are lower.

You can run cool and quiet, but i found it can cause issues, so i use mr phenom's tweaker now, to set custom cool and quiet.

Disabling one core...??? How do you do that?
