When overclocking CPU Voltage above 1.387500V the DRAM LED goes RED and system will not boot?
Hi, I hope You are all well. I would much appreciate any help as I am becoming quite desperate now. I have Asus M5A97 R2.0 EVO motherboard and AMD FX-8320 Black Edition Processor and G.Skills Sniper 2x4GB DDR3 1866 MHz RAM. I tried to overclock my processor to 4.5Ghz. The multiplier 22.5 looks to be working fine and system is working with voltages on AUTO as long as I don't start playing games or something, then it obviously crashes. But my problem is that, when I tried to raise my CPU Voltage more than around 1.387500 V the DRAM LED goes RED and system will not boot. When not overclocked all works fine and NO DRAM LED light I actually have to turn off my PSU, take out my CR2032 battery from motherboard and reboot with default settings otherwise either black screen or first Asus screen frozen. I read people was overclocking this configuration to 1.45V no problem. I believe I have a good cooler Arctic A30 and cannot go above 1.387500V. I also read that some people was mentioning that G.Skills may need to raise the RAM MEM to 1.55V, which I also tried. It was working alright with CPU voltage AUTO, but again when overclock the same things. Any help much appreciated.
My Bios setup goes like this

I sorted myself. The problem was I had the LLC on AUTO and that was the source of all problems. When I set it to Regural (OFF) I can run it now 4.5GHz on 1.45V stable no problem.
