Sorry but you're wrong.



UD7

I can't see DrMOS on the above X58 mobo. If I'm not mistaken then the first and only (so far) Gigabyte mobo which uses DrMOS is the UD9.

"Having said that, Unlocked Power is not solely about phases. Gigabyte have replaced their traditional motherboard power design and are now using more modern integrated Driver-MOSFET chips, which differ from standard MOSFETs in that they feature a 3-in-1 design with the Driver IC, top MOSFET, and bottom MOSFET all in one package. Among other things these new MOSFETs have faster transient response, provide more stable the power to the CPU, and more efficient."

MSI uses DrMOS (and APS) since the mid of 2008. MSI's first DrMOS equipped mobo was the P45 Diamond. Check this short presentation.
