First Test
Vcore
Program : linx 0.5.8

Config :
bclk 200 ,multi 20 ,uncore 2400, dram 1200 ,HT off first.
vdimm at stock, qpi at stock,EIST/TM/C1 etc etc all disabled
also since ure running gtx295 make sure u set 512mb more than ure 1792mb so i guess 2304mb.
6 channel interleave, 4 channel interleave, leave dram at 2n 8-8-8-24 tRFC 88

test ure cpu vcore with this always at 1.25,1.2625,1.275,1.28750,1.3,1.31250,1.3250 etc
the inbetween causes more instability.Proven in many mobos.

pass linx 10 rounds. reboot and try again. atleast twice

Second test
VTT
Program : Prime95 25.8-25.9 64xbit


Config :
set dram to 1600mhz qpi to 3200mhz dram at 1.65v-1.68v , vtt at 1.26-1.36v
set prime95 to large fft and then custom change from run fft to atleast 5.4gb
for ioh/ich voltage, ioh analogue, ich voltage
try this combi either 1.11,1.10,1.05 / 1.21,1.2,1.15

U need to pass atleast the full 1024mb and 896mb full 15 of each.

Notice the errors u get for more vdimm and vtt. Later find the exact ratio aka difference between vdimm and vtt. This will help u in later overclocking for higher ram speeds.

Once u pass reboot and retry again. atleast 3 times.

then try with better ram timing

Test 3
reconfirm ure ioh/ich, ioh analogue, ich 1.05 voltage
Run hyperpi 32m 4 threads, 8 threads, and then 16 threads

Make sure u can pass it atleast twice one after the other
and then pass again upon reboot twice again.

This is how i clocked

the others err ram timing a bit more complicated. more to feel.
