**LETS SEE YOUR PILEDRIVER OVERCLOCKS - LET ME START WITH 5GHz+!!**

Don't know about it being wrong they seem to handle overclocking really well if your standards are as low as getting a CPU-Z validation, getting them fully stable is another matter entirely.
 
You can set an overclock with very low volts like that and it be stable enougth to get a CPU-Z validation.

You might even be able to brows the net or listen to music with it, try and do something just a little more strenuas like unpack a Zip file and *plonk* its gone....
 
Went back to a 24 Multi only, had to raise the vcore slightly to make it stable, but temps seem better strangely, ambient is similar to before at 19 degrees, measured from the baby monitor :)







All power saving options still enabled as well (C1E, CnQ, C6), everything else on Auto. Have set RAM to 1600 up from 1333 :D
Not bad for an Antec 620 H20 in push pull setup (exhaust configuration)

50c Cores and 55c CPU.

Its feeling the winter cold, you have frost forming on that CPU at those temps, crank it up, what are you afraid of? :D
The cores will push past 60c no problem.

My Thuban gets hotter than what your getting and that has a lower threshold.

Edit- turn CPU-NB LLC and CPU-NB CC up a notch, also set your VRM's to extreme, they will get a faster transit response and increase stability at overclock, you have the same Sabertooth 990FX if i remember rightly? they have 10+2 Phase VRM's, use them. what’s the point in spending £130 on a top of the line MOBO if your not going to use it? might as well have gotten a 'Biostar crap-x 920 delux' :p

Thanks for the help.

4.8 would appear to be this chips sweet spot, after this I need to increase vcore sharply to get things stable, which in turn drives more heat.

I am trying to balance the performance to heat and longevity ratio hence my reluctance to push things much further on this cooler.

Testing 4.9 now, core temps circa 54 so far.
CPU-NB LLC set to high and CPU-NB CC set to 110%
FSB @ 204, Multi 24 @ 1.49375v seems stable.

Does the multi go to 24.5?

In anycase if your getting core temps under 60c that’s pretty good.

I would be happy to run it 24/7 like that.

I did read on OC.net a response from an AMD rep saying safe volts for the fx-8### was 1.55v, your comfortably within that and your temps are also well in the safe zone.

Is this your cooler? http://www.overclockers.co.uk/showproduct.php?prodid=HS-005-AN&groupid=701&catid=2330&subcat=2359

Yep, that's the cooler, I have replaced the stock fan & added another for push / pull, Scythe GT1850's.

I'm going to keep playing around with the settings, I am positive there is some more tweaking to be done :)
 
New rad installation is up and running. :) Pics in the link in my sig.

Temps are much better, 10-15C cooler on the socket and VRMs, and 15-20C cooler on the cores. :cool: It's quieter too.

It's allowed me to push to 4.9ghz 24/7 (1.56v under load, 1.536v unloaded) and also given me the room to OC the 30nm Samsung RAM to 2133Mhz 9-10-10-24. I know this RAM could do 2400Mhz but then I'd be into clocking the NB to prevent a bottleneck and the minimal gain doesn't seem worth it.

I'll post some temps later during a long encode to prove it's good for proper hard use. :D I don't think I can get 5ghz still though with this chip. I did have a go but it'll need over 1.6v for stability under heavy load and that's really not worth it. The general consensus seems to be 1.55v is about max for 24/7 use.
 
I am messing around at 4.8Ghz on the 8320 and it is running fine.

However i am choosing to ignore the fact that P95 AVX tests will send the temps into the stratosphere.:)
LA LA LA never heard of it all good here, P95 what.

5Ghz is a bit elusive though.
Runs desktop OK but put any significant load on the chip and it freezes.
Could try much higher vcore but that could be a death sentence for the VRM's.
