deciding between, MPower, UD5H, GD65.

post #1 of 7
Thread Starter 
So I've been reading reviews, threads about motherboards and I've narrowed my options.

Gigabyte UD5H

MSI MPower Z77

MSI GD65

I'm planning to oc to about 4.5ghz. I'm reading topics about digital to analog vrm and phase counts on these motherboards. I really can't decide. I can't go with lower boards like UD3H as it has VIA chipset for its audio hence not compatible with hackintosh which I will be doing to with this setup. And also, I can't go with UD4H and U4P because they have ALC892 which is inferior to ALC898 which these boards have.

1. Do I really need the offset voltage for overclocking because from what I've read, the MSI doesn't have it and Gigabyte does?

2. About quality components like VRMs and chokes, etc, I've seen threads saying that Gigabyte has better components than MSI and also that Gigabyte has digital PWM while MSI doesn't. Will I benefit from that difference?

3. Last, if I would go with MSI, is MPower worth the extra over it's lower GD65?

Thanks guys.

some people here are probably going to really disagree with my opinion on this....

1.) No you don't need offset voltage.

2.) People make a hissy-fit quality of VRM components and cooling VRM's. On low end motherboards, VRM can cause issues. All those motherboards you are looking at are high-end, and they all have excellent quality VRMs.

The difference between analog and digital VRM's is negligible. Analog does have a smidgeon faster response and digital is a smidgeon more accurate, but I feel the difference does not matter in the big picture. People with both analog and digital VRM's are both achieving the same overclocks with equal ease. I feel it doesn't really matter which you go with.

Some people fuss about VRM temperature. What most people don't know is the switching devices MOSFETs in VRMs are good to a internal temperature of around 130 C.

3.) I would use things like number of SATA ports, number of USB ports, layout of PCI-E slots, number of E-SATA ports, BIOS options, and quality of audio to decide your final choice. These are the things that i feel really matter in the long run.

Personally, I've had phenomenal luck with ASrock. :-)

Wow thanks for the answers on my questions. I've narrowed my choices to MSI Mpower and Gigabyte UD5H.

I really like the Mpower because of it's slick looking board which the gigabyte sucks because of the blue color. and Mpower has wifi and bluetooth. But the only thing that holds me back is that the Mpower lacks offset voltage which gigabyte has. Is it worth it to go with a board with offset OC? I don't know if there is any workaround the lack of offset voltage of the Mpower.

I've looked into the Asrock Extreme 6 but thought about it because of the VRM designs, components and quality (I'm not sure if the extreme6 is in par with these boards).

Is the MSI Mpower worth the extra $20 over the UD5H? considering the lack of offset voltage?

The Mpower boards are all hand tested with P95 for 24 hours at 4.5-4.6GHz. The chances of getting a bad one are virtually non existant.

any workarounds for getting offset voltage with the MSI Mpower?

So, what would you guys choose, Gigabyte UD5H vs MSI Z77 Mpower?

MPower it is rock solid.

Do you OC? How do you do when it's on idle? without the offset voltage.
