hi guys, i recently purchased a q6700 and have noticed some strange things about it.
first whenever i do any overclocking (2.66 stock to 3.2)cores 0 and 1 seem to be rock solid stable at stock vcore, but cores 2 and 3 produce errors in prime95 within 1 minute. i can manually increase the vcore and cores 2 and 3 will run just fine and error free.
second i have noticed that cores 2 and 3 run about 3 to 6 degrees C COLDER than cores 0 and 1. i have an aftermarket heatsink with AS 5 and i know how to secure a LGA 775 heatsink.
i dont know much about how these processors work but looking at the temps and the additional vcore that cores 2 and 3 require. that makes me think maybe those cores for some reason are not receiving the same voltage as cores 0 and 1. less voltage means lower temps and instability when overclocked.
idle temps are
the temp difference between the cores stays the same even at 100% load(quad prime) and the hottest core does not break 55C at stock clock and 59C at 3.0 ghz
not asking for help on overclocking here im just asking your oppinion about what could be going on with my core 2 and 3.
ok just looked at core temp and its showing a VID of 1.2625v, cpu-z is showing a vcore of about 1.15. what is VID?
VID is voltage identification. It's the max spec the processor needs to run stable at stock frequencies... It's also what you are setting in the BIOS when you change vCore. The vOffset is there to prevent the voltage from going over the VID.
VID - vOffset (vDrop) = Windows Idle Voltage (CPU-Z)
