Does all Sandy Bridge motherboards have decent power phase ?

post #1 of 25
Thread Starter 
Yo all.

I'm eventually planning to buy the GA-Z68MX-UD2H-B3 and I am unable to find anything about the power phase on the website or Google in general.
And then I was wondering ... If I'm going to buy the 2500K and OC it to 5 GHz, is the overclock solid on all the Sandy Bridge platforms or do I have any reason to be worried about particular ones ?

I haven't heard of a single P67/Z68 that has a lesser competent power phase for overclocking but I'd like to be on the safe side of knowledge.


Regards, and thank you beforehand. Any input is highly appreciated.

It appears that this particular board has a 6 phase VRM. (source:http://www.overclock.net/intel-mothe...omparison.html)

First 5GHZ is a very demanding OC, more than likely you will only be able to do 4.5 - 4.8ghz 24/7 with reasonable voltages (assuming you have the cooling). But if you upgrade every few months than the life of your CPU probably doesn't matter.

Generally Matx boards lack the VRM that full atx boards do. I would not recommend trying to OC with this motherboard. If you can go full atx, I would have to recommend the UD4.

A bit low if I'm going for 5GHz on the 2500K, isn't it ?

It will suffice, considering a Sandy at 5GHz with about 1.5v Vcore would draw around 100w on full load.

I like my 12+2 though

That Gigabyte mobo has 6+1 Phase power design..

I would personally go for Asus P8Z68-V motherboard which has 12+4 Phase power design (12Phases for CPU and 4Phase for iGPU)..

Supports SLI/CF has 2x SATA3,4x SATA2,1x ESATA, 12x USB 2.0,4x USB 3.0 etc..

It's around 30$ more expensive than that gigabyte Z68MX-UD2H mobo but much better..

CHEERS..

My MATX board does 5GHz just fine. I just didn't like the temps so I bumped it down to 4.8GHz.

You will never hit 5GHz on a board that cheap. Do NOT skimp out on your mobo, a board's VRM is only one part of a much larger equation that leads to good (or poor) clocks.

The fact that it is mATX has nothing to do with your OC, see ROG Gene boards. You also have a nicer board.

5GHz@1.5V will not draw just 100W

$160 is a cheap mobo? Did you even look it up?

w00t? I believe power consumption at that point would be twice the normal one...so, we are talking about not less than 150W.
