4+1 phase mobo? - Page 2

post #11 of 15
4+1 is fine for SB

especially with MSI intel boards, as they use really high quality mosfets, and they are heatsinked

sadly, can't say the same on the AMD side

imo if you could swing it i would get this, http://www.newegg.com/Product/Produc...82E16813131705 , it has a 12+2 phase and overclocks a 2500k to 4.9ghz proven here, http://www.bit-tech.net/hardware/mot...p8p67-review/3 . a motherboard is one of the those tings you don't really want to cheap out on.

MSi used 35A DrMOS same as GB uses for P67, they are pretty good DrMOS, and they willg et teh job done, but i wouldn't expect over 5ghz under load.

35A x 4 =140A MAX for CPu core with max 1.7v=238watts of output power to the CPU, i measured 200-250watts at 5.1ghz load just for the CPU. So yea.

As mentioned above, MSI puts out good Intel boards. It's their AMD boards that are plagued with the bad 4 phase VRMs.

Also as stated, 4+1 is just fine for overclocking Sandy Bridge. It's not a power hog in comparison to previous generations of intel processors.

Take a look at this board:
ASUS P8P67-M Pro

I've seen people getting pretty nice clocks out of it, nearly 5ghz, sometimes at 5ghz or more and it doesn't have many phases at all.

If you're concerned still, just slap a spotcool fan on your motherboard and point it at your mosfets, you'll be fine.

im using the gigabyte p67a-d3-b3. i was worried because it was a budget board and is 4 phase. It runs my 2500k @ 4.5 with no problems. i have not experienced any problems with this board.
