Rams: ADATA AX3U2000GB2G9-2G. I think its 2000mhz but some how it runs only max at 1600mhz. Good to know: I bought 2x2gb one time and same rams 2x2gb other time. The only dif between them is timings: 1st 2 sticks( 9 9 9 24 ) 2nd 2 (9 11 9 27) Board supports up to 2200mhz.
If I run them at 1800/2000mhz ect system just resets default. Any ideas?

CPU clock 19 x block 200 so I run stable 3.8ghz
QPI x36
SMM (PSD) 8 (if I chance it to 10, to get 2000mhz, system wont start)
so Memory (2002) runs on 1600

In rams settings performance enhance TURBO
DRAM timing AUTO

Just chance QPI/VTT from 1.355 to 1.415 and memory multiplier from 8x to 10x (2000mhz) system wont start...
VRAM 1.7
