Gigabyte's P67A-UD4 Sandy Bridge Motherboard Preview

[sin0822]

The count on the Driver MOSFETs, I am unsure of which was their first, but all X58 board have Driver Mosfets which is DrMOS. It has to do with the output on the driver MOSFETs. Gigabyte uses a seperate iTE chip for phase gearing and switching. What were the first MSI boards? DrMOS was used instead of old fashioned highside and lowside mosfets with a separate driver.
The PWM is just the controller for the phases, the VRm is the phase design, so the MOSFETs are part of the VRM, not PWM. Rensas is what MSI uses on their newest board, Gigabyte Vishay made MOSFETs output the same amperage, and on top of that you can actually go and multiply single MOSFET output by number of MOSFETs. MSIs 6 phase +1 is one MOSFET per channel, Gigabyte uses 4 MOSFETs per channel, but each of gigabyte's mosfets are equal to MSI's in output, so in reality if MSi can multiply their phases by 4 than gigabyte can too.

That is all I am going to say, FYI gigabyte makes their own boards as well, which almost no OEMs do anymore. Foxconn and ECS are their makers now, You want more info read my review ont he X58A-UD5 or P67A-UD7 skip to VRM design on both boards, you will learn a lot.
