the issue I have with recommending an 8 core e series chip is that it wont outperform a stock 6300 in gaming environments.
at stock & with turbocore enabled the 8370e will only turbo to 4.3 on 3 cores & drop the other cores to 3000mhz to keep within the tdp limits.
overclocking,disabling apm etc raises voltage & draw & will essentially remove that e suffix from the equation & will 99% likely result in the same throttling issues as youd get with a standard 8 core 125w cpu.
the 6300 youll be able to push 4ghz on all cores & still stay within a 100w tdp or therabouts - the extreme 3 will cope with that fine.
amd turbo core is worthless on newer gaming titles,it can actually be detrimental to performance & introduce all sorts of stutter & lag.If anyone builds an amd rig nowdays my first suggestion is to disable turbo straight away - it worked ok in 2012/2013 when titles were at a max twin threaded,it doesnt work so well nowdays at all
I usually disable turbo core straight off for any gaming rig. I have actually had the time to work with several FX 8370E processors now. One of my best selling rigs is based around this motherboard CPU combo (the GA-970A-UD3P and FX 8370E) that I can get for a total of $210. It makes for a good all around budget build. I have found that the FX 8370E will usually hit 4.3Ghz and sometimes 4.4Ghz without any bump in Vcore. These chips have AMDs very best binning and are really good overclockers at low Vcore and lower heat than older FX series processors. The OP has 4+1 power phase, however with Turbo Core disabled, multiplier overclock to 4.3Ghz and no bump in Vcore @ 95W TDP his board is capable of handling an overclock on all 8 cores of 4.3Ghz. No other 8 core FX is capable (other than maybe the FX 8320E) of that as all the other 8 core chips are 125W TDP and too much for the 4+1 power phase (especially while overclocking).
While it is true that the FX 8370E @ 4.3Ghz won't have much if any edge on the FX 6300 or 6350 @ 4.3Ghz that is true for all FX processors. Just like an i7 holds no lead over an i5 in gaming (because hyper-threading usually doesn't play a factor in gaming) the 8 core FX processors and 6 core processors have basically the same IPC. If if a game can only utilize 3, 4 cores then you not going to see any difference between the 6 core and 8 core processors at the same clock speed. Where the FX 8370E will hold a big advantage is if the OP wants to run highly multi-threaded applications like rendering, video editing, streaming game play, ect. An 8 core FX will outperform a 6 core FX when it comes to running highly multi-threaded applications.
your wrongly assuming that leaving voltage on stock settings in bios keeps it at that voltage even when overclocked - which it doesnt.
the voltage will increase exponentially along with clocks speeds automatically.
while you wont see big voltage increases on auto on a good quality 8 phase board like the ud3p you will with that asrock board - Id bet my bottom doller itll need 1.4v to hit 4ghz with an 8370e.
the vrm's wont cope at all well with that voltage.
to put into context my 6300 on a ud3p ran at 4.6ghz at 1.36v ,on the 4 phase board its in now it needs 1.38 to hit 4.3ghz - the exact same cpu not another 6300
the 8320 is running on my ud3p at LESS than stock 8320 voltage - yes its a well binned chip picked from a batch of a dozen but that low voltage is at least 50% down to the board.
The ud3p has pretty much the best voltage regulation Ive ever seen - the best on a 970 series board & still a match for all but the upper end 990 series ones.
Its pretty much incomparable to that skanky quality asrock board.
Im not saying the 6300 is a better cpu than the 8370e - Im saying on that asrock extreme 3 it will be the best you can do performance wise without running into major problems.
