VRM on Motherboards?

post #1 of 4
Thread Starter 
Just a quick noobie question here, what does VRM do on the motherboards? My option for a 1155 is down to two, the asrock extreme6 and asus p8p67 pro. When comparing them to the chart in this thread :

http://www.overclock.net/intel-mothe...therboard.html

they're both pretty much the same except the asrock costs $40 more and has a few more features but my main question is the VRM. The asus board has 12 and the asrock board has 18. What does this do and how much performance am I gaining with the board that has 18 compared to 12.

My build:

------------ (motherboard)
Core i5 2500k
Noctua NH-D14 with an additional extra fan
Corsair AX850
HAF 932 Advanced
(2) Gigabyte SOC GTX 560 Ti in SLI
G.SKILL Ripjaws X Series 8GB DDR 1600
SAMSUNG Spinpoint F3 1TB

thanks in advanced!

Mainly about VRM related disasters, but some solid info on what they do and why they are important.

So is 12 phases safe enough? Because if so I'll just go for the cheaper asus p8p67 pro, as I don't need the extras from the asrock.

yes but it all depends on what type of MOSFETs are used and what type(aka how much current) the inductors can pass. 12 is just fine, they use the same PWM, and depending on the model, asrock and asus use the same parts.
