AMD noobie needs help overclocking FX-8320

[Charliew87]

Hello,

So basically, Im building for a friend. Managed to get the CPU to 4.3ghz@1.28vcore which seems to be pretty much awesome. The temps however, are not.

Im using an Antec 1220 cooler, 240mm rad in push config, arctic silver 5 and an FX-8320.

Idling at abouts 40-43c, loading to 62c in about 2 minutes of prime.


The thing seems stable as all that, and running games/apps are no issue. Maxing out 55c after physXing it up in borderlands 2 etc. But priming brings be to a halt.

The water temp seems to mirror the CPU temps pretty nicely, which in my world translates to great CPU->cooler contact/transference. However either the fans that came with the cooler are PITIFUL, or the radiator itself isnt really transferring that much heat.


What should I look for? Help please.

What are the ambient and water temps? From what I've gathered, you want to look at the delta between ambient and water temp to determine if you have enough rad space (or if you need better/additional fans). It seems like most people are happy when that delta is 5-10C under load.

First of mate, get rid of this "arctic silver 5" and get some MX-4 or something in that linie.

AMD is not my place on CPU, but after what i know they will get HOT when doing OC on them.

But will gief ppl whit more insite on AMD cpu room here

lol, the first post was from feb 2013. :/

If its crashing under Prime95 then its not stable and youve still got some work to do.

Id suggest downloading OCCT and Intel Burn Test for stress testing. OCCT doesnt need to run as long as Prime95 and it has plenty of cool monitoring features. OCCT is the main one I use to find a stable overclock then when I think Ive found it, Ill run 20 passes of Intel Burn Test and if it passes that, I know Im golden. You want to do both. My 8150 will pass IBT at 4.8 but cant get passes OCCT or Prime95 at anything higher than 4.5.

Set the CPU/NB voltage to manual and set it to 1.15V. Its usually set to 1.25 or 1.3 by default and that can build up the temps. Set LLC if you have it to Ultra High or whatever the 2nd highest setting is on your board. If its set to Auto, its likely bumping the voltage under load and going way over the 1.29 youve got set.

Now run OCCT and see how it goes. If it crashes pretty quick, then you need to up the voltage a little like to 1.30 or 1.31. Then try OCCT again. If it crashes again or CORE TEMPS (not CPU socket temp) gets to 62C then stop it cause thats too hot.

Thats a pretty high idle temp so something doesnt sound right but try these steps and see what you get.

Thank you for all the suggestions .

The AS5 is supposed to be good. I actually missplaced my MX-4 and was going to use that or EVGA frostbite but a friend tipped me off towards the AS5. Still trying to find a favorite .

I think Im leaning towards the fan or the radiator itself being shit. Fans are an easy thing to check since they sound a lot anyways, so I said he'd have to buy some SP120's.

Anywhos, going up for newyears most probably. We live 700kms apart. By then the thermal paste has cured, the fans should be there and the cpu stability at 1.28vcore@4.3 ghz should have been tested enough.

Really looking forward to taking my new friend for another spin by then . If 1.28 is enough for 4.3ghz, I dont dare to think what 1.4vcore should be able to reach.


Also. Gskill trident 1.65v 2400mhz mems at 9-9-9-24 at slightly over 1900mhz 1T. Thats really good imo. And ASUS is a dream to overclock on, I dont know why Ive been favoring Gigabyte this long : /.

Nothing at all wrong with AC5. It's been around a while but it's still just as good.
