when trying 4ghz.. i cant boot into windows with the odd BSOD. i am feeding the cpu with 1.511volts is this enough... how do i know i am not going to **** it up by giving it more juice. i can boot into windows at 3.9 and complete benchmarks with 1.49 volts.. or is it the ram hitting its ceiling at 890 at 1:1 at 4ghz? :confused:

Tetsu is right my friend..

hitting 64-65c under load at 3.9 and idling at 33c... hitting 4ghz is for self satisfaction

not 24/7 use...

at 3.9 my ram is 5-6-6-20 2T at 868 mghz.. what do you suggest for 890 mghz.. this is a bit of a grey area for me...

But if i use a lower multi will this not stress the mb and possibly do damage.. fry the VRM's..

right I lowered the multi to 8x with the fsb still at 445 and mem at 890mghz giving me a 3.56ghz clock.... booted into windows ok but temps are higher with an idle of 35-37c and the voltage in cpu-z is up and down between 1.512 to 1.490 so what does this establish?

i will try tomorrow on a higher voltage unless anyone has a different opinion?

it's useless tried all different volts on mostly everything and changed ram timings....still getting the BSOD :mad:

... anyone got any more ideas :confused:

... i have heard of this chip going to 4.25 without water cooling,..
