7990 bottlenecked by FX-8350 due to vdroop. PSU or Mobo?

Don't listen to unhelpful people. You have probably overclocked your processor more than your board and CPU cooler can handle. How long did you run Prime 95 of AIDA64 before you determined your overclock was stable? A lot of people have problems overclocking high on that board.

My suggestion is to get back to stock and make sure you're not having problems.

This guide is god-mode for overclocking FX processors on Asus boards:

Just make sure you run the stress tests properly.


That is one of the guides I've used. It can handle stock speed ok without this issue. Actually, I don't have this problem until I go above 4.5ghz. The CPU seems to be ok with the boost, but the voltages get all screwy.

Well, then I think you have your answer. One of the most important parts of that guide is to run the stress tests correctly and watch the temps. It's pretty clear about where the limits are. Even 4.4 GHz is still a 10% overclock. Your voltage seems a little high, and though it's possible you got unlucky with the silicon I think you might be pushing it further than you need to. Prime 95 works really well for AMD to check this.

Damn... so, you don't think switching mobos could solve this problem? I'm stuck at 4.4ghz?

Well, switching motherboards could solve it, but I don't think you're nearly at that point. Go ahead and save your current profile in the BIOS in reset everything back to stock. Start over clocking again from scratch, and make sure you are using the absolute minimum voltage you need every step of the way. You have to use increments. Most processors with our architecture can get 400~500 Mhz more on stock voltage. If you want to overclock right it takes time and sometimes many attempts.

So don't do anything drastic yet. You're already talking about getting new parts. We aren't there yet. Start from scratch and maybe report in when you start raising voltages. Push stock as hard as you can (in increments of course) in Prime 95 until you start to get errors. And watch those temps. If you're going to mess with your hardware you have to have patience. We'll figure out what's going on.

I like you. Thanks for the help. I'll check in within the next few days when I have more time to mess with it. I did not make a drastic jump immediately and have been running smooth for months on a 4.4ghz OC at stock voltages which is impressive. However, I want more performance as to match the 7990, but every step I take to push it further causes issues.

My best bet would be the main board.

No problem man. For what it's worth though, this forum is a difficult place to get help if you use AMD hardware and it's worth asking for help on real hardware sites, especially before you make any drastic changes to a build based on a perceived problem. Always have to have patience.
