The ASRock AB350M also is a 3-phase Vcore, but at least that one has a heatsink. Doubled low-side or not, I think 3 phases is getting down to the bare minimum for AM4 processors. Even if MOSFET temperatures come down, PCB temperatures can still stay really high when the Vcore phases are insufficient in quantity / physically really close to each other. You can paste some copper heatsinks on the 9 Vcore MOSFETs and put the small fan back on, but I'm not sure what it'll do for you. So, 3+2.Īll the other MSI budget boards make do with a 4+2 doubled low-side, so I'm not sure why MSI decided to remove a Vcore phase from this board entirely. Only 5 phases total, from some VRM testing videos it seems like only the left 3 phases are Vcore.

It might be time to make an upgrade on the board and/or CPU Yeah, I thought this was similar to the VDH it's significantly worse. The price tag and component choice on that board is probably low enough to make buying copper VRM heatsinks/thermocouples a questionable proposition. I'm surprised the power delivery on that board has allowed you to do this much thus far. These Zen+ 6- and 8-cores look competitive with Matisse parts at stock speeds, but draw a helluvalot of power north of 4GHz. On the A PRO, I'm almost certain that those are mediocre-to-terrible ON 4C06N, Sinopower or Nikos parts.ġ.35V is no joke. 4 Vcore phases with doubled low-side MOSFETs is enough for a stock 8-core or a stock 12-core *maybe*, but only with higher end 4C029 and a large enough heatsink.

Seems that the A PRO can be substituted with the VDH PRO in the VRM dept.Īnd honestly it sounds about right. Picture of cpuz stress test, barely gets over 70c and package power is hitting 107w whereas ibt it got to 77c and 155w package power at the same clock speed and settings which is a big Some of the VRM lists don't have any data on the B450M-A from MSI, but the LTT VRM list places the board in the lowest possible category and recommends only for OCing 4-core Zen/Zen+/Zen2 CPUs and APUs. Not sure I have a sensor on them but they are bare and the board is one of MSI's lower end B450 boards, I'll have to monitor hwinfo and see if it's throttling in games and other workloads though I suspect it's not and it's just heavy workloads like ibt and cinebench which wouldn't be the end of the world until I can get the vrm's under control

Will definitely get some vrm heatsinks next week and hope they have the desired effect, as I don't plan on buying a new board until ryzen 5000 series and want to upgrade to a 3000 series cpu until then. Seems the 60mm fan isn't enough to stop the throttling at 4.2ghz as it was when I was overclocking with the wraith spire to 4ghz but the airflow of the air cooler likely aided it whereas I have an aio now with no airflow over the board apart from the 60mm fan now.
