Thanks for the input guys, i will tell him to try those out, the memory is all the same, patriot viper 1600 c9

If the ram is C9, your friend should try the looser advanced timing controls
47-7-7-14-104-7-28 with 9-9-9-28 standard timing controls. The turnaround settings should be whatever your ram sets automatically when you use 133 BCLK @ 1600Mhz.

But the main area to adjust outside of memory timings for 12GB to work is the voltage settings for the MCH and the DRAM volts/subvolts.
Changing the DRAM subvolts should be your last option if all else fails.
Also the clock skews of 150-200ps had some positive results for me for certain overclocks I tried. One of my cores would be stuck at 100% usage trying to load gui.exe(ET6) during windows logon. Changing the skews solved this.
