    Posted: 08 Jul 2018 at 2:01am
I bought this motherboard from local shop, after i bult pc, pc started freezing sound for 1 sec every 20-40 min i tought that problem is driver, but no. Then i installed fresh win 10 pro but problems are even worse pc freezes after 2 hours of normal usage, sometimes i need to hard reset pc, somtime pc restarts without freezing. I tested ram with memtest86 and no errors are found, tried booting pc with one stick of ram, tested psu with multimeter i was getting stable 12v, tried different gpu, tried other hdd, but none of those fixed problem. So i read that this mb has bad vrm cooling, so i took apart pc and gived mb to local shop to give me my money back, they sent mb to test and after 9 days they called me and said that there is nothing with motherboard, i was speechless. And i builded pc again but that sh*t is still happening. Do any one have any suggestions what shud i do now. Here are my specs but i thing it doesn't really matter so much.

Return the mobo i you can and take another model / brand.

It's regarding the voltage, the auto overclock or ryzen and the lack of llc in the mobo.

Try to disable core performance boost (no xfr) and set a fix core clock to avoid the cpu going from idle to performance states trying to avoid the peaks up and down in the voltage every time cores are pushed with more or less frequency.

You may use the old bios, prev to the release of raven or pinnacle.

Is your local shop going to rma the board for you with Asrock? Try to get other board right now, waiting is a nonsense.

Keep using the 350M Pro4 with ryzen APU its a bad idea, but there are many other cheap boards that runs ok. 

May be much better for all (you, shop and Asrock) swap the board at Asrock RMA support returns the unit to your dealer.

Yesterday I moved my PC to a place with more airflow.

For now, the uptime is about 25 hours with no freezes so far. This is record
