fx-8320 throttling when overclocked by even 100mhz

[Aletoivonen]

So I overclocked my fx-8320 with the catalyst control center CPU overdrive. When I don't have the overdrive enabled, my processor is running on a stable 3,5ghz like it should, but when I enable the overclocking which should make it run at 4ghz, the frequency goes down to 1,5ghz during gameplay, and around 2ghz in windows. I ran the overdrive test, its required to even overclock via accc, and it easily ran 4ghz without heating too much. I tried increasing the freq just by a 100mhz, to make it run at 3,6ghz, but still the throttling happened, so its not a heat issue. So why doesn't the overdrive work at all even though the test did work?

Welcome!

First, what motherboard do you have this in? It may not be able to handle it (even though the CPU is on the support list, yes). At your earliest convenience, please create a signature with your system specs (may need to wait a couple of posts). If you cannot create one, please list your complete system specifications.

I have the Asus m5a99x evo r2.0. It was not the cheapest but it wasnt very expensive either, around 120€. Ill make the signature first thing when I have time, posting from mobile atm

EVO is on an 'approved' list as it has a 6+2 VRM.. so it shouldn't be doing that.

Hopefully some of the AMD guru's get in here soon and help you out. Im an Intel guy...

Sounds more like green features than throttling. Disable turbo core, cool'n'quiet, c1e, c6 states, APM master mode. Enable HPC. I found the functionality of AOD to be lacking, would be cool if it worked but I don't think it does. Best use I found for it was upping my vCore on the fly, and then use that info to apply settings in bios.
Check out the links. One of them's right there in EarthDog's sig. Read the stickies at the top of the AMD mobo/cpu forums.

Thanks. I got the cpu running at 3,7ghz, but, now accc tells me to do the oc test again. I cant change my clocks and they are stuck at 3,7ghz. I think it happens every time I change something in Bios. Is there a way to avoid this?

Yeah, get rid of that crap
Seriously, get rid of AOD and ACCC. You don't need it. AOD can be useful for adjusting voltage live, rather than having to boot to bios, but I've never seen anyone using ACCC. I wouldn't trust AOD stability testing either. You need Prime 95, HWMonitor, and CPUz

AMD OD isn't bad software but don't use it to OC. Do that from BIOS as was suggested. Like Dustin said make sure the C&Q is disabled along with APM and have HPC enabled. That should stop any throttling. I don't see any mention of a CPU cooler. What are you using the stock H/S ?
CCan you run Prime95 blend at stock speed? If so While it is running use HWMonitor free version to check temps and voltages. After about 20 minutes take a SS while it's running so we can see what's going on

Oh I forgot to mention I have a CM hyper tx3 evo, and my case is a zalman z9+ with 3 case fans. It isnt a heat issue cause it throttles if I OC it to 3,6ghz but using the Amd turbo core it can easily handle 3,7+ ghz. Something about the settings make it so I couldnt manually oc via softwares. Ill try to do stuff via bios and post results when I have time to experiment.

Disable turbo core. That should fix the issue.
