I didn't want to make the conversation more complicated so I just said "CPU overheating" but really if any component overheats the board will downclock.

The VRMs generally run a lot hotter than the core of the chip but decent boards will have a good heatsink to cover them and cool them down to where they don't matter.

You might just have a board that put 0 effort into the cooling process of the motherboard.

Yup I just tested 4.3ghz with auto turbo voltage which gave me a vcore of 1.192v and I did not notice any downclocking or voltage drops. I was suspicious of the vrm's. Is there a way to check vrm temps?
And I passed an hour of prime at 4.6ghz @ 1.28v. Max cpu temp 75C. CPU was downclocking on some tests tho. And another thing, .086 and .090 additional turbo voltage both gave me 1.280 vcore. .090 would have a higher max vcore in HWinfo of 1.288 but it would still only do 1.280 in Prime

An hour of Prime is just the beginning. When you can get past the 12 hour ,and then the 24 hour mark, that's when you can call it stable biggrin.gifthumb.gif

You're going to want to set the vcore offset to 0.005+
And manually adjust the turbo boost offset to get the best results.
Also set the LLC to the level which keeps your Vcore at the correct amount, typically level 2 or 3.

I was able to get 4,5ghz on 1.16vcore So you'll most likely be able to do slighly better than what you're at now if you manually adjust the settings.

Sorry I meant additional turbo boost voltage not offset. My offset is at .005. And my mobo only lets me choose 0,50,and 100% for LLC. (probly cus its a cheap board.)

50% is usually the best setting anyways. thumb.gif

jrizzz,

The Vcore is reported in .008 increments, the voltage adjustment stepping being in .004, so you may notice no change in software because you just have not crossed the next .008 threshold, but you can trust that your VCore is ~.004 higher than it was before.

If you have a tower cooler, you could try orienting the cooler so that the VRMs have some active cooling. Just look at your PCs internal layout and figure a way to get some airflow over the VRMs. Also, thermal pads also dont last forever, and I believe that ASRock only secures their vrm sinks with push tabs, so they come off and go back on easy. So replacing them may not be a huge chore. Looking at a picture of the Pro3, the VRM section is pretty puny. Get some cooling on those things or back it down.

Try OpenHardwareMonitor for VRM temps

No sensor diodes are there (in most motherboards) so the only solution is a cheap heatgun temperature gun.
If you run OpenHardwareMonitor you are looking for a temp under the mobo called "VRM" or "MOSFET".

Here's a temp gun for $20 - http://www.amazon.com/Non-Contact-Thermometer-ETC-8380-Instant-read-Temperature/dp/B00837ZGRY/ref=sr_1_8?ie=UTF8&qid=1414745863&sr=8-8&keywords=thermal+gun

Alright I'll take that into consideration. If worst comes to worst i'll just buy a better board but for now i'll try as hard as i can to cool those vrm's. I appreciate the help guys.
