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

Ok, so... voltage was "around" 1.4v like I said. I can't give any exact numbers since I have already set my BIOS back to normal, but below 1.4v @ 4.6ghz and I get instant BSoD during Windows loading screen.

The temps reached max 64C during Prime small FFT and generally below 60C during games at 4.6ghz and 1.4v.

The CPU can't pass small FFT above 4.4ghz at pretty much any voltage up to 1.45v. However, it can pass, right now, at 4.4ghz and stock voltage.

I am using a Hyper 212+ with MX-4.

My plan was to get a Sabertooth 990fx or Crosshair V Formula-Z, a water cooler like a h100i or NZXT Kraken X60, and a new PSU like a AX850, Toughpower Grand 850, or XFX 850 Pro Black Edition. I think these upgrades would definitely cover all bases to help me push this chip.

That's a lot of upgrading for just a CPU overclock. Why don't you just pick up an Intel CPU and motherboard instead?

That is, also, an option. It won't be for a while, anyway.

I think I found your problem.
How is your case airflow? Because my OC should be pushing 140w+ TDP, but my super-closed oven case hyper212+ cooling setup won't touch 60 unless it's the middle of the summer.

Hmmm... seriously? I guess I will re-apply thermal paste and see if I can't get the temps lower. I have the HAF 912 w/6 case fans all running full blast when gaming.

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.


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.


Sincerely, most people have Intel, and thus are much more well-versed with Sandy/Ivy overclocking. Frankly, I could help anyone with Sandy/Ivy (possibly Haswell) overclocking without looking up anything, but AMD overclocking necessitates research on my part.

And patience is a virtue. That's why I've got it tattooed on me.

Well, assuming you have the thermal paste it wouldn't hurt re-apply it and make sure the heat sink is properly seated.

However, did you check the specific notes on the overclock guide that specifically reference your exact motherboard?

M5A97 Notes:

It seems that the LLC functions on some of the M5A97 Motherboards does not function as intended.
If you run into stability issues and strange voltages using LLC, it's recommended to leave it set to Auto.


I thought at some point you said you turned this on. Seems to be a quirk with that board. Like I said, don't go making sweeping changes with your hardware until you are absolutely sure you know what the problem is. You will almost definitely regret it. If we figure out what is wrong and you still want to then it is on you. But paying a large percentage of money for a very small percentage of performance is generally not a good idea.

Edit: TheFeshPince posted...
Specs:

Asus M5A97 R2.0

I have disabled APM Master Mode and all other power saving options in BIOS as well as enabling LLC. None of these changes have made a difference. I still get vdroop eventually. Some of these options enabled or disabled can make the vdroop occur more often, but either way it happens.


So yeah, that might be it, and you said your voltages were wacky. Your temps still seem a little high so I would make absolutely sure everything is okay in there as well. Remember, it's 62C core temp (package in HWMonitor) and a little over 70C socket temp (Temperatures --> CPU in HWMonitor) for AMD. Let us know how it goes.

No, man. It's always around 22C in my house.
