I just received some 4x8GB of g.skill DDR3 1866 , model F3-1866C10Q-32GXL .
I installed them in my Gigabyte 990FXA-UD3 rev 1.1 with latest F9 BIOS.
By default, the auto settings POST at 1333 speed.
I am not able to POST this RAM at 1866 . The motherboard always complains about overclocking error. All the other BIOS settings except the RAM are stock. CPU is FX-8350 .
The specs for the RAM say it is 10-11-10-30 and 1.5V .
Things I have tried :
1) setting DRAM EOCP to DDR3-1866 .
That didn't work . It tries to set a higher RAM voltage and wrong timings.
2) EOCP disabled
set memory clock manual
memory clock x9.33 (1866 MHz)
Under DRAM configuration :
CAS # latency : 10T
RAS to CAS R/W delay : 11T
Row precharge time : 10T
Minimum RAS active time : 30T
And leaving voltages as auto which should be 1.5V for the RAM.
But the mobo still won't post and complains about OC error.
Any idea ?
