4+1 phase vs 8+2 phase - Page 2

post #11 of 26
No one can accurate tell without testing. More VRM circuit phases does not mean the CPU will require less voltage for a given OC. There is a lot more involved than just voltage and ripple when OC'ing along with the mobo design, engineering, production quality and BIOS.

thanks hopefully i will see when i get the board i guess.

I will say more VRM's used to be better... that's not necessarily true anymore. My newish Asus M5A99X-EVO has digital VRM's which provide better current and cleaner power than many beefier VRM setups due to better efficiency and control.

In general, more VRM's is better - but a board that is say.. 6+2 with digital VRMs vs a board that is 8+2 with digital VRMs and I would choose the 6+2 in that case.

It's not more "VRMs"... wink.gif We're talking VRM Phases and how they influence the VRM circuit, current capacity and ripple. The only means to tell is by accurate testing.

not really better with more phases.
my Asus HD 7970 DC ii compare to reference hd 7970. in over clock.
stock voltage Reference 1125/1475 memory performs perfect.
asus dc II lots of antifacts in BF3. even got higher stock vol.

Thanks for the correction in terminology.. I do believe my degree in electrical engineering grants me an sufficient understanding/experience of current and ripple to note the difference between digital and analog phases, though.

Perhaps if I had a bunch of boards to test I could prove my point.

As I've said here and in other threads, the only means to know how well or poorly a VRM circuit functions is by actually testing it. The number of phases by itself does not determine the current capacity or ripple.

I didn't say the words "More phases means better."

I did say digital power delivery tends to be cleaner and more efficient.
post #19 of 26
typically more is better.

Rarely will there be a board with more phases that is worse.

More phases = more $$$. It makes no sense for a manufacturer to produce something that is more expensive but performs worse.

However, as with any generalization, there are multiple exceptions.

Anyone heard of a 16+3 phase board?
