ASRock X58 Extreme + F3-16000CL9T-6GBTD

[v1332090]

Model of the motherboard: ASRock X58 Extreme (Bios 1.60)
Model of the memory: Trident 6GB (F3-16000CL9T-6GBTD)
Model of the CPU: Intel Core 7 i920

Hi. The memory is not stable at DDR3-2000.

Boots into windows 7-64bit and crashes within 2 mins of Prime95 stability test.

Settings:
CPU Speed: 2667Mhz
CPU Ratio Setting: 16x
BCLK: 167
Intel Speedstep - Disabled
All voltages auto except Dvimm Voltage: 1.654v
Mem setting: 9,9,9,24,2T

Memory works fine at DDR3-1800 using below setting (Tested Prime95 for 3hrs+)
CPU Speed: 3700Mhz
CPU Ratio Setting: 20x
BCLK: 185
Intel Speedstep - Disabled
All voltages auto except Dvimm Voltage: 1.654v
Mem setting: 9,9,9,24,2T

Anything speed above 1800 crashes..

Any recommendation bios setting?

Has anyone successfully and stably run DDR3-2000 speed on X58 motherboard?

Appreciate if someone can show me the light! Thanks!

Do you have the latest BIOS? Try different multipliers to see if it will have a difference. Some motherboard/CPU combinations only like certain multipliers. Try 143 BCLK. Let me know how that goes.

Thank you

Might need to raise vCore and tRFC, or one or the other
