They are basically the components on motherboard that provide power to processor.Because of continuous power flow through them they get hot,cheaper vrm get hotter faster than good quality vrm. If vrm get too hot they will reduce the power being supplied to the processor forcing it to downclock/get slower. If you overclock then even more power flows through the vrm than normal. That is why good mobos always have good vrm & are usually costlier but not all costly mobos have good vrm(hence the reviews).

I think the real phases should be minimum 4 and anything more than 4.
Check the real phases against the exhibited phases by the respective motherboards.

To see real phases in CPU VCC or SOC VCC?

Different supply voltages for processors on the socket AM4:

  • CPU VCC, the supply voltage for the processor cores
  • SoC VCC, the supply voltage for all other systems on the chip such as integrated graphics processors or memory controllers
So CPU VCC is primary factor to see then comes SoC VCC.
CPU VCC should have minimum 4 phases or more than 4.

Search on reddit by typing mobo model followed by vrm.Checkout buildzoid videos on youtube reviewing amd mobos.You cannot simply judge a mobo VRM quality just by reading its tech specs unless you have some background in electronics.

Ok, lookalikes rocket science for me, Not deep know ledge in Electronics.

Anyway some what understand about Mobos in detailed manner.

Thanks for sharing both of us.

as far as these lower end boards are concerned,are they still suitable for running something like a ryzen 1700/2700 if they are not OC'd at all and are used at their stock speeds only?

However it is strongly recommended to not cheap out on mobo when using something like ryzen 1600/2600(with OC plans) or 1700/2700(no OC plans) especially when the entry level(above garbo/garbage tier) MSI B450M Pro VDH mobo is available for just ~6.6k. Even logically it doesn't feel right when you combine a Rs.16000 processor with a 4-5k mobo.

how's the gigabyte aorus x470 ultra gaming motherboard in terms of reliability?I found a combo deal from a seller on olx on a ryzen 2600 cpu+aorus x470 ultra+32gb ram for 35k-wondering whether it would be a good idea to get it or not.

^^ryzen 2600--16000
msi b450m tomahawk--10000(check above table,no gigabyte mobo is even in same class as tomahawk even when priced much higher than tomahawk)
32gb ddr4 3200MHz ram--16000

So no,it is not worth it getting this combo deal from olx.
