Help!! How do I change my Corsair 1866 in bios for Gigabyte 990FXA-UD7

[Todd_4]

Hello,

My build
Corsair 900D
Corsair 1200 Axi/indv sleeved w/ Corsair Link
Amd 9590 8 Core 5gb liquid cooled cpu. Running 1 4x120mm Rad.. All Koolance Liquid loop.
Corsair 4x8gb 1866 Mhz C9 Memory.
Nvidia Geforce Gtx 980
Lg Blu-Ray
Double din lcd fan controller
Samsung Evo 256gb SSD boot drive
WD Raptor 1Tb secondary...


I'm sure there's more but irrelevant, my problem is I cannot get the memory to run at 1866mhz. Even with the preset options in the bios. I've never Overclocked anything before so this will be my first. Forgive my noobness.. But is it the individual voltage to each memory channel that needs to be changed also? I tried just choosing the option to run at 1866 and windows crashes every time saying system unstable. Also Stock is only 1333mhz so I'm losing the extra there and on the cpu as well. Stock is 4.7ghz but can be OC to 5.00 GHZ and it is liquid cooled. My ram isn't liquid cooled yet so I wouldn't want to max it at 2k ghz that the 990fx allows but at least the standard of 1866 would be nice. I would like to up my CPU speed to 5 constant since it is liquid and temp is extremely low right now.

Thanks in advance to anyone who reads or replies..

Todd

Does your BIOS show a EOCP option? If so enable that and select 1866, might need to raise the DRAM voltage + 0.06

With all RAM slots filled and so much memory, MC (memory controller) in the processor is overloading and would need extra voltage on an already hot processor.
