aha ... so the "MCH/DRAM Reference" is somehow connected with A/B reference?
I’ll set it to 1.050, but do you think I should try to lower the ram voltage a little bit?
2.060 with 1.030 A/B reference and MCH/DRAM Reference? like what you gave Hoss331 ?

will set it to standard, I just kept it to Turbo cuz that’s what it was when everything was at stock

do you think I should set “Static tRead Value” at 8 instead of 9 like your settings? Specially that mine already shows 8 as a default value!

didn’t really understand but I’ll give 266/2.50A a shot
you mean "CPU PLL"? it's @ 1.50 not 1.15

manny thanks for all the help everyone

Sure lower it away, if it passes keep lowering it


SURE! That is what I was meaning about using standard and trying better Tread values and write training. Set your to stardard and see how low your Tread value will boot, that is after you get your multi and ram speed set to your liking.

I would follow Hoss331's advice with setting a higher RAM Multi, Hoss helps me with my settings and is pretty good at this stuff.

I would not worry about the Thermal Monitor and your current overclock. Your not going to experience high load temps so Thermal Monitor is going to be useless for you. Even at my clock speeds sometimes I do get my chip a bit hot(If I linpack) but the important thing to do is monitor your temps and even if they get above 70C as long as your not running that hot for a long period of time your not going to "fry" one of these Q9550/Q9650 chips.

266/2.50A didn’t work … BSOD during windows startup.
anyway latch@333 with multi@ 2.04B is good for running@ close to stock for me (1020)

i wonder why ET6 show 0.9 for DRAM Termination & channel A/B reference & MCH/DRAM reference though they are 1.050 in bios!
after work i'll try 2.060 with 1.030 , if it worked i'll give 1.920 with 0.960 a shot

I managed to pass P95 at like 1.16** vcore, can I set it to that or it’s not a good idea to go below stock?
