***official amd 83x0 overclocking thread***

You're on an H80 right? Temps seem ok, certainly the core is nothing to worry about. 22x to 7x sounds like power saving rather than throttling - does it happen when you're stress testing? You shouldn't be getting VRM throttling unless your case has no air flow.

Yeh, H80 on the Low Fan mode (anything else is plain too loud!)

I have the case open at the moment, but the H80 rad sits right over the VRM, so its not idea. I need to do something about that, but not sure what right now - there's barely any space - I'll post a new thread for help with airflow soon.

Any link that explains why not to use Prime? I've seen it recommended by people for years?

I thought I had a totally stable overclock at 4.8 which was prime95 stable (12 hours) and also LinX stable (20 passes), but when my brother in-law used the system to watch some films and some light gaming, it locked up after 3 hours use.

Bumped the voltage a bit and hasn't happened since. In the end, as 8-pack says, just use the system normally and see if it is stable or not. The beauty of LinX is it is fairly quick (and dirty) in terms of getting an idea of overall stability in about 10 minutes. Prime95 has to be run for quite some time and even then, not totally reliable.
 
I think part of the problem with P95 is it is not optimised for the bulldozer architecture - it just makes it really hot but doesn't test well for stability given the architecture.

I am using AIDA64 - as it allows me to stress individual processing units (use floating points for max heat - CPU/cache/FPU for stress test - enable GPU stress too to see how that may add to CPU temps). I run for 2-3 hours and then play games...

Ill try that. Thanks

AIDA seems to be stressing the computer far more than Prime - Navigating the system is really slow now. That's good, I assume

ok very good theres 2 ways we can either downclock that and say start @ 4.0 or you could try increasing voltage alittle and try that

but 4.6 should be well within the limits of your chip so maybe it just need voltage
 
Yes mate I did the same RAM as you, it wouldn't load, and when I eventually got into BIOS it had all reset except for the advanced menu part, like extreme and 130% ect.
