How many watts should I give my AMD Athlon X4 860k at 4.0 ghz

[Spaniard2001]

So I've been using my PC for about a year now, and just recently I picked up a Cooler Master Hyper TX3 EVO and do I was thinking of overclock it given that I've heard a lot about it so far. My question is, with the cooler I have, would it be possible to raise the clock speed from 3.7ghz to 4.0ghz and if so how many watts should I give it? Also if it makes any difference my motherboard is an ASRock FM2A68M-HD+.

It should be able to go to 4GHz easily with that cooler but you can't give it any more Watts but Volts. AMD recommended is maximum 1.5v (Volts) so I doubt you will need anywhere close to that at 4GHz. As it may behave differently between same processor, you'll just have to try it yourself. Raise just one notch at a time and see where it gets you to.

Why would you oc an 860k to 4ghz when already boosts to that from the factory? Heres what I did and I run an A88X Asus board. All I did was set the APU multiplier to 44 or 45 depending on if you want 4.4 or 4.5ghz you may have to do 43 for 4.3ghz if yours isnt stable at the higher clocks. Leave everything else on Auto. Also check make sure your memory voltage is at 1.5v some people incliding me have issues with the board wanting to run the memory at 1.65v for some reason. F10 saveing your settings and you should be good to go. This usually works well becuase the 860k runs high voltage from the factory usually around 1.45v to 1.55v. I have run my girlfriends 860k at 4.5ghz for over a year now on all auto setting with no issues. The nice thing with leaving everything on auto is you can leave the AMD Power now fuction enabled in the bios. This allows the CPU to down clock and save power with light work loads.

My old 760k did 4.4ghz at stock/auto voltages, which was somewhere around 1.3V. It did 4.8ghz at 1.55~ish volts not accounting for VDroop, so I left it there for a long while.

My first-gen TX3 (non-evo) cooled my 760k at 4.4ghz admirably well, even during the summer heat waves. I'd imagine a TX3 Evo would be able to cool your 860k at 4ghz. 860k and 760k are slightly different architectures, so obligatory YMMV here.
