 Because if the VRM were the primary source of the problem you'd be held back by thermal throttling and not voltage. If you need additional vcore to stabilise at a particular clockspeed and you're not thermally limited by the board or chip, then your motherboard VRM and cooling solution are playing less of a role than the quality of the silicon you D20'd.

It does not seem to be able to handle overclocking. Either that or I have bad CPU lottery.

Best I could achieve was:

3700Mhz Core Speed
1.28V core voltage
3 cinebench runs - pass (1642 score)
20 minute CPU-Z stress testrun - pass
Stable temp 71c


3800Mhz Core Speed
1.400V Core Voltage
3 cinebench runs - pass (1684 score)
30 minute CPU-Z stress testrun - pass
Stable temp - 85c

Core voltage has to be set really high to even get 3.8Ghz.

Now Im left wondering what to do. I don't want to regret getting mATX as I really prefer this form factor and love my new Phantek evolv mATX case...

Maybe the new x370 matx board from biostar will be better for overclocking?
Im not an overclocker, then should be good for me ?
Problems in stock frequency ?

I also can't decide which one to buy - b350m Mortar or ab350m pro4. I am liking the fact that MSI got more bios updates and I like the placement of board elements more and it has 4 fan connectors which is just what I need. But asrock has p-state which is nice for overclocking, 3+3 VRM kinda sucks though... I am limited by mATX formate so in my opinion there is just no other alternative to these 2 boards. Asus prime b350m-a is quite nice, but it has no heatsinks at all (but there are mounting holes for it). If it was possible to buy heatsinks from ATX version of this board, then ASUS one could be my choice. Gigabyte has bad VRM components so I don't consider it. Biostar might be good, but there is just not enought information about it, I found just one review of b350m mATX in whole internet and there are almost no feedbacks...

Probably you will see more boards coming out soon with Computex just around the corner.
I'm waiting for asrock to show their stuff. Still hoping they will do a OC-Formula on the Ryzen AM4 tongue.gif
