AMD FX6300... Throttling?

[Darkshadowhaxor]

Hey, I recentily noticed while rendering video my FX6300 is throttling at 63*c.. Its running at 4Ghz stock voltage. Any ideas?

Yeah FXs don't like heat a ton. Max operating temp should be 70° so you are kinda close.

is that throttling or fans ramping up (and then temperatures going down?)

it looks like the red line is temps

Fans are not ramping up. Red = Temp. It throttles down to 1.4Ghz

that its over heating. Clean out the fans. My 8359 does this too but it's due to the VRMs not handling the heat, at the time 1.47v for 5ghz.

I didnt think that CPUs thermal throttled at 62.4*c ... This is a fresh build that not the issue. I just need to adjust my fan speeds if that is true

An FX CPU shouldn't throttle at ~62c, unless you have some power saving options on (even with that up to 70c should be fine without throttling), basically the CPU should be able to reach all the way to ~88c (at 90c its protection kicks in and stops the PC, this protection is in place because over 90c there's a risk of the glue holding the metal lid to melt).

 

Of course by no means i say you should run an FX at those temps, just saying though what the limits are. Your problem is the VRM's on the mobo, i believe they are not handling the load and are overheating, what's your mobo ?

could be the vrms as I said before. My temps with about 60c at 5GHz but would drop to 1.4 because of the vrms.

That definitely looks like a VRM issue. What motherboard are you running?

I had an issue with my 6300 (on a cheap mobo) when under load it would drop to 1.4GHz because the VRMs were getting to 100+ degrees. The fact that it gets to 63 degrees could just coincide with the VRMs overheating. When idling and on regular power settings does it adjust the clocks depending on load? Mine did not when running on dying VRMs. If yours does the same it'll confirm the VRM problem.

 

My problem was very similar:

Asus M5A78L-M LX3 I think

I have put some aluminium heatsinks on the VRM's but I guess its still a VRM issue. Thanks all. 

[OfficialSiRiS]

Yeah that's just a 4-phase VRM on that board, probably not enough to supply an FX 6300 at full load. 

Check to see if there's any visible damage on the VRMs like there was on mine, (http://imgur.com/xCDidSG)

if there is you'd definitely want to look into a new board.

Can't inspect. I have aluminum heatsinks on stuck with thermal adhesive
