First off, I am on a high end custom water loop for cooling 2x120mm RAD + 3x120mm RAD. See image below.



I am 100% stable at 4.816ghz with the settings below

Crosshair V Formula (non Z)
1703

Multi - x20
Bus - 240mhz
HT Link - 2600
CPU Volts - 1.48v


Socket Temp Idle - 32*c
Socket Temp Load - 51*c
Core Temp idle - 20*c
Core Temp Load - 44*c

CPU/NB Volts - 1.35v
NB Freq - 2600
Memory Patriot Viper XTreme (Intel memory, I know) - 1866mhz (native) See image below for AUTO timings (I know nothing about memory timings and control)


All of the recommended settings in BIOS have been disabled etc per RAJA's tutorial.

Ive been overclocking for years and I'm surprised I can only pull 600mhz overclock above TURBO on this 8350 when my 8120 got over 1.3ghz overclock.

I dont know what else to try. If I add anymore FSB, I get cores that will fail during Prime95. When I try to do multiplier overclocking, my comp wont even POST. Im dead serious, even if I add just x2 more multi, no matter the voltages etc, the PC WILL NOT POST.

So, what I have concluded, this CPU just wont go past this 4.8 wall and HATES CPU multiplier overclocking


Things I have tried to gain 5.0 stability.

Upped voltage as high as 1.53v
Reduced Multiplier and added FSB (no POST)
Reduced NB and HT freqs to stock
Reduced Memory clock to 1333mhz

What would you do to try and hit this evasive 5.0ghz?
