Should be able to get DDR3-1800 range. Then try lowering timings as low as possible. That motherboard should be able to handle BCLK 180, it gets sensitive once you near 200.

i have recently settled on the ram running at 1600mhz with tightened timings.....system runs fine....but every now and again when i turn off the computer then back on windows only detects 4 gig of ram....then sometimes 6gig why is this?? would this suggest a faulty stick of ram??

Try reseating the memory modules, sometimes they may not be seated correctly. Or try the other slots to see if you will have the same results.

For DDR3-2000, try a higher memory ratio.

CPU Clock Ratio - 18x for 3.0GHz
QPI Link Speed - AUTO
Base Clock Control - Enabled
BCLK Frequency - 167
Performance Enhance - Standard
Extreme Memory Profile - Disabled
System Memory Multiplier - 12

Uncore & QPI Features
Uncore Frequency - 4000

DRAM Timing Selectable - Manual

CAS Latency Time - 9
tRCD - 9
tRP - 9
tRAS - 24

Enter these for the other three as well.

i have tried those settings still didn't work...have re tested all 3 sticks of ram individually at 2000mhz using super pi and memtest running at the same time....No errors.....all ram sticks work fine by themselves....as soon as i put in two or three sticks board won't post at 2000mhz....will only post at 1600mhz...reseated all 3 ram sticks 3 times....windows will only detect 4 gig of ram although i should have 6.... If i use my spare ocz ram windows detects all 3 sticks....buy why wouldn't windows detect the g skill stick when they all test fine 1 at a time?? is this a motherboard concern??

Send those in for a new set. Hopefully the new set will provide better results.

have sent e-mail in for rma will let you know how i go

I recently recieved my rma thanku, but every time i put a module in the 4th memory slot 2g isn't being reconised.....but if i put my ocz ram in that slot it is reconised why is this?? I have tested your 2000mhz sticks individually and they all work fine so i know its not your ram....
