NOT QUANTITY. The AsRock 12+2 phase is weaker than Asus and Gigabyte 8 phase and on par with Asus 6 phase. AsRock 8 phase is about on par with strong 4 phase designs. That being said your cooling is you most likely limiting factor followed by your motherboard.

I lean towards board first, then cooling.

As it's second hand I didn't get the Soundblaster thing and the NIC but I don't care. To be honest I don't understand a lot of the functions of this board, there are so many for fine tweaking that I am too lazy to take the time to learn it all. The Sabertooth wasn't intended for me as my board still worked at that time, only when that finally died did I get this CHV.
I also recommend the Sabertooth as it's an excellent board and unless you can get the CHV super cheap like I did, or you intend to break records, it will serve you just as well.

E-chips are binned for low voltages. Maybe you should consider getting a "standard" bin 8370?...
Then you could run and test the new chip on your current setup and just see how it goes??
If the new chip breaks through to 4.7/4.8 and possible even higher? Keep the new chip and sell off your old 8320E here in the OCN classifieds or perhaps on ebay?
It is possible that your particular 8320E might max out on heavy stress testing (Prime/IBT) at ~4.6 with "high-end" air cooling.
I had a launch release FX-8120 and launch release FX-8350 running on an original CHV... I later sold them off while running Intel but this past November (Black Friday/Cyber Monday) I purchased a new AMD combo... A CHVF-Z as well as both a standard 8370 and a low voltage 8370E for binning...
The 8370E was pretty nice... But my 8370 turned out to be a even stronger
So I decided to keep and run the 8370 and then sold off the E variant chip.
My FX-8370 @4.8GHz DDR3-2040C8 Prime blend on an open air bench with custom water cooling:
After taking all of this, as well as help from many others, and some Google searches in to account, I believe my MB is struggling with this chip at 1.4v+. I found two threads where people had the same issue with the 1.4v wall, and they both had my MB. Due to this, and the fact that I want another MB anyways so I can have two rigs, I will likely be getting another MB before anything else.
Thanks for all the helpful responses everyone. +rep Edited by pshootr - 1/27/15 at 7:46pm
