Power Phase Design/Quality

The question: What matters mores, MORE VRM regulators? or better quality VRM regulators? OR all VRM regulators the same?

Okay, so originally I had an FX 6300 paired with my ASUS M5a97 r2.0 motherboard and a HYPER 212 EVO. It worked like a dream and overclocked really well, I had my 6300 at 4.6 Ghz, prime95 stable, matching an FX 8320 at stock. This left me with plenty of headroom too, around 52 degrees full load under prime.

Then MicroCenter just HAD to go have a sale on the new in box FX 8320 CPU for 100$ and I couldn't resist. With a 4+2 power phase design, this worked for the 6 core but I find its not enough juice for the 8320. The max overclock I can get is 4.3 Ghz which is good, but the board cant supply enough juice to go further (temps are fine).

So I bought a new motherboard looking for 8+2 power phase design, and bought the ASUS M5A99FX PRO 2.0 motherboard to remedy this problem so I can push my overclock. I thought it had 8+2 power phase, but its 6+2.

I saw the Gigabyte GA 990FX UD3 has 8+2 and when compared to the ASUS with 6+2 the ASUS was recommended over the Gigabyte. Which leads me to the original question, is 8 power phases for the CPU always better than 6? or could the 6 be of better quality and perform equally/better?

sorry for the long post.
 
Anyone with a M5A99FX PRO 2.0 + FX 8320/50 care to share how far they could overclock? Ill be happy if I can get 4.5/4.6 Ghz out of it, even if that's all the motherboard can push out safely (VRMs) my Hyper 212 will become my limiting factor right around that frequency I imagine...Should I return this for the GIGABYTE GA 990FX UD3? it has 8+2 power phases, but people all across the board almost, still recommend the ASUS over the GIGABYTE, even with 2 more VRMSs..

My friend has that board and has an 8320 and got it to 4.4 GHz.
It performs perfectly fine. We dont wanna go any higher than 4.4 because he's got a pretty bad cooler. But I have seen people get it to 4.8GHz with no problem.
 


4.8 Ghz on the M5A99FX PRO 2.0? or just 4.8 Ghz in general? cuz I know the 8320/50 can do 4.9/5.0 Ghz
 
Ok so after looking into it more, the ASUS is good quality and performs well and is accurate with its settings. 6 Power phases for the CPU should be sufficient for a medium (4.5-4.7) overclock on air cooling. If I had a H100i liquid cooler, then I might feel a bit disappointed in my choice...but for the HYPER 212 EVO I think the board will pair well. Thanks for the replies guys.
