i really feel frustrated now, i thought a 4ghz oc would be so easy, but i cant even have it right now, i really dont know what is the problem on my system.

im using antec 620 close loop cooler, im amazed with its idle temps arround 20 to 25 deg. but in full load it reaches 65 when having a 4ghz oc, before i re seat my cooler the max temp is 60 deg only, i thinks that the thermal paste cannot do its job anymore,

Is it normal for my 8320 to require massive voltage increases past about 4.55GHz? I know my 2600k did this at a huge level, so I assume it is completely normal.

Also, I assume the maximum safe voltage if keeping the temps in check is 1.55v? In your guys' personal oppinion, do you feel like this is actually 24/7 safe, or would you want to only run that voltage for benching?

EDIT: @ Sazz - it says 4 Cores 8 Threads? Just curious because when I ran my 8320 in CB it noted all 8 Cores and 8 Threads. Did you turn off some cores for overclocking?

When you use the Windows Hotfix for Bulldozer there are a handful of apps that now report Bulldozer/Piledriver have 1C/2T per module.

Guys does anyone here experienced downclock when cpu temps are high around 68? cpu temps not core temps, my core temps are pretty stable at 58 deg oc full load. and how can i cool and i dont even know where it is located ayt my motherboard asrock 970 extreme 3

I've been using the Hotfix since they released the second part of it, it did make a difference in performance, not huge, but it was there.

There are some issues with it just hanging the system at full stock for some people, among other things. Others with OCs that pass any bench or stress test under the sun, but prime fails 2 mins in.
The people in this thread are divided; those who trust prime and those who don't. m0bius and I are among those who don't. Keep in mind our distrust is only for the Bulldozer/Piledriver module design CPUs.
It's not a matter of "trusting" prime, for me. I find it to be a useful tool. Since I can get prime95 stability on my 8350, I would claim that prime95 CAN'T be broken for PD. It works. If the exact same software doesn't work for somebody else, then it's due to a difference between our systems.

However, if you were to say that prime95 for the PDs is WAY too picky and that you get perfectly good results without having to be prime95 stable, how can I argue??? Only you know how you're going to be using your system and what kind of stability you need. No argument that prime95 finds problems where other tests don't -- that leads to an inevitable conclusion that some systems will be 100% stable IN USE without having to be prime95 stable.

Because of how I use my computer, I want prime95 stability. YMMV.

Would anyone happen to know if a 850 watt PSU is sufficient for 2x 6950's slightly overclocked and a 8350 pushed to 5ghz?

You would be cutting it a little tight @ 5ghz full load with GPU's at full load.


Good thing for you very very few games can load 8 threads fully.
