How can i get my A10 7850K to run at 4.5ghz?

I have this in my rig:

Asrock fm2a88m extreme 4+ motherboard
Kingston hyper x 2400mhz ram (can only run them at 2133 on my mb)
Gigabyte R9 270X OC (stock speed)
Artic freezer 13 cooler

Dont know if you need any other info.
I would very much like precise settings for mb so i can raise it from what it is now (4.3ghz) to 4.5ghz.

Thanks in advance :)

Yes. Upgrade to an Extreme 6+ and you may have a chance. I doubt if the vrms on your board can hsndle the heat from upping the voltage high enoiugh. You had better have excellent cpu cooling as well.

hmmmm, then again maybe that would be an upgrade?

How dare you post this overclockers.com nonsense here. Banned.

No but you're right. The difference between a H60 and what he has is just not worth the currency.
OP try for 4.2 if you can get higher than that be happy. Just watch vrm temps.

I check it with my finger. If it burns me, it's too hot

An H60 is an inadequate cooler for handling temps at full load. H80i minimum.

4.5 may be a bit much for your air cooler. I have my 7850k sitting happy at 4.5 w/ 1.46v... But I also have a swiftech h220 in push/pull keeping the heat down.

What temps at load are you getting at your current OC? Also, have you tried disabling your iGPU? It might help keep som heat down as with the 270x you won't be using the iGPU right now..

The Swiftech H220 is a great cooler, I have an H320 for my. FX-8350. Push-pull is a waste of time on a thin radiator and just adds to noise. Go to Martin's liquid labs web site and do some reading. All you'll get out of push pull is 1 degree Celcius. On thick radiators it will be a lot more effective.

Yeah, the main reason I have it in push/pull is to get a little more airflow over my VRMs. I have the unit sucking air into the case from the top, with an exhaust out the back and found the little extra air helps keep the heat on the board down. I eventually plan to expand the loop...more out of fun than for any noticeable benefit

I have a large super tower case. My cooler is top mounted on exhaust. I have a spot fan on the vrms and a whole host of other fans on intake , including one under the vrms on the bottom of the motherboard, a large 230mm fan on the windowed side of the case, 4 intake fans in the front drive bays, which only have ssd drives to cool, and a rear intake fan as well.

I just got it stable at 4.5 i bumped up the voltage to 1.525 and now it works :)
I played little more than an hour of coh2 on a steamworks map with pop cap on 800, so there was a lot going on, and yes also a lot of lag with so many soldiers, tanks and effects. I checked hw monitor afterwards and here is my temps:

systin 38c
cputin 51c
auxtin 63c
tmpin3 40c

I have no idea what they meen, eccept for the cpu one ;-)

Doesn't seem worth all the extra volts I'm running 4.2 undervolted 1.368

I agree. Bragging rights is nonsense. No point in wasting all that power for a speed that is going to throttle under load anyway.

You can't . It is apparently built into the chip.

Try different settings and decide for yourself it temps are good and performance, its up to you.

Typically you won't get bsods because of temps but instability so you may want to either increase vcore or lower multi.

I want to amend my last post. I had an email discussion with John Taylor , head of AMD world-wide marketing. I mentioned the issue of the cpu throttling under load. I suggested that this should be controlled by the user, through a bios option, not shoved down everyone's throats indiscriminately. He stated that Kaveri's sweet spot for energy saving vs performance was about 35-45 degree Celsius. In any case he understood our angst about it and would raise my suggestion with the development team. So there may be a possibility that with AMD's guidance bios revisions may be issued by Asus, MSI, Gigabyte, Asrck, and Biostar that would allow us to run Kaveri under load without throttling. It is not a definite yes, but they are starting to listen to our issues.

I have down clocked it to 4.3 with voltage 1.425 and temp is currently at 56c running prime95. Maybe voltage was wrong before with 4.5ghz but i think i will stay on 4.3 since its running prime95 with no problems now :)
