Oh GOD! I read through quickly and touched up some things here and there. You have some issues, but are not entirely related to JUST the processor.
First off that board is not made for low end slow memory modules. That's why it posts stock 11-11-11 timings. You would look for some High speed memory sticks that will better agree with the bios's default settings. So what I had done to cure the memory dealings was got my hands on some Corsair memory and ran 1100mhz daily ++ on timings 11-13-13-36 ( If memory serves today) I just selected what speed I wanted and let the board set those timings instead of the Cas9 at 2133mhz the sticks where rated for. Had no issues ever. 1200mhz was not an issue.
Another problem you have is the constant beating that poor bios takes. Now this goes hand and hand to the CPU. I struggled with My FX-9590 before AND after I removed the IHS plate off of it. It's hot. Way hot. Will not ever be stable running even remotely near that supposed 70c threshold. You want to be able to maintain temps below 55c both socket and core for this chip to work good and stable.
If this was my rig.....
First, a nice loong hard cmos reset. 12-24 hours in a nice dry atmosphere.
Secondly, would put down some real moneys into a cooling solution. The H115 in your sig is a joke when it comes to handling 220W while at a 22.5x multiplier the CPU requested P-state voltage is up around 1.5250v. The Cpu can request this voltage on the millisecond level especially when it's using turbo. This applies even when your slow temp reading software does not display it. All while running this configuration stock.
This chip will NEVER run 4.7ghz stable under 1.490v. Tried many times for lower. However if you lower the frequency at this voltage you gain stability.
Must run manually implemented voltage. Must run LLC at Ultra High to pin that desired voltage.
Had to run 2x 120.3 rads push pull with another 120.2 rad for safe measures. Top speed was 4.9xxghz While running 1.5250v. Temps where an issue over 62c. Hang ups where an issue at over 55c.
Here's a thread that I wrote up some time ago.

If you find a better read for the understanding of this processor, I'd like to see it. But in a nut shell, you bought a system that is meant for heavy extreme cooling and overclocking. Not a daily rig.
