Asrock Z77 Pro4-M - OC Problem - Page 2

post #11 of 16
Thread Starter 
Here is a review I read earlier on. It seems like the mobo is more than capable of an overclock.

It definitely sounds like it should work for you. My CPU was running at 4.6ghz after all. That should be a lot more power used even if it's similar voltage, I think?

You could do an experiment with an open case or just board on its box on a table. Then have air blowing directly on the VRM and see if this changes things. You would know for sure it's the VRM temperature and its protection throttling the CPU and not some other strange problem.

When I had this problem I played around with the idea of buying this: http://www.advancetec.co.uk/thermalright-hr-09s-mosfet-heatpipe-cooler-type2.html

But that idea felt stupid as I could have just bought a pricier board in the first place. The shop I bought from was willing to take the board back and let me buy something else even after nearly a month of use so I did that.

Btw... I used whatever BIOS was the most current in February or March this year. The board had a pretty neat ability to go online and search and download the newest file by itself from within the BIOS and that's the BIOS version I used when I had problems with throttling. You might want to try different versions to see if something's fixed.

The mobo arrived today so it's on its box since it arrived as I haven't got my 350D yet. I have updated it to the latest bios already but problems was still there.

However, I think it is sorted now. I put one of my SP120's right in front of the VRMs and its been running Prime 95 for the last 10 minutes at 3.6GHz. It just passed test 10 and still going. I noticed the AUXTIN temperature in HWMonitor is now below 49 degrees and I think that's what was throttling my cpu. I'll remove the fan and see if the problem comes back. I think once it gets installed in a case it should improve more as there will be airflow going right pass the VRM components.

It should be. There must be something wrong with your OC settings. Try to ask here.

If VRM was the issue, that's another board where ASRock uses D-PAK MOSFETs. They're unpredictable lol. They use those on Extreme 4 boards, but don't on full sized Pro 3 and 4. So mATX one must use them too. If you remove the heatsink and confirm that would be nice.

I removed the fan and the test failed again. Now I know that it is in fact the temperature and not the settings. I'll have a look at the mosfets tomorrow and let you know.
