Which voltage is right and which temps do i go by?

post #1 of 7

temps and voltages.JPG 392k .JPG file

Ok so as you can see i am getting different voltage readings from different applications and i'm not sure what to follow. 1.5v i feel like is too much to be true but i can only get 4.4ghz stable with that. I moved it down a little bit in overdrive and i got errors in p95 saying worker stopped illegal sumout possible hardware failure but my computer still runs fine. In cpu-z it says its only 1.39v which seems like a reasonable voltage even though i put the voltage up to 1.5 in overdrive and core temp says its 1.5 v too. so i'm confused which one do i use. also where should i look for my temps, in overdrive or in coretemp or somewhere else.
any help would be greatly appreciated. biggrin.gif
all my components are in my sig. my h70 has 2 sp 120's in push pull.

CPU-Z is the correct reading for actual voltage going to the CPU. Most motherboards exhibit a certain amount of Vdroop, meaning that as the CPU draws more power from the socket, the voltage drops slightly. To counter this, there is a setting in the BIOS called Load Line Calibration (LLC) which increases voltage as more power is drawn in order to counter the effects of Vdroop.

Firstly I recommend doing all overclocking in the BIOS and re-doing your overclock from about 4GHz to get a feel for how much LLC you need. For reference I'm currently running at 4.5GHz with 1.45V target voltage but 1.44V actual voltage with LLC set to very high. Remember that LLC will increase your load voltages so don't try more than 1.45V with v. high or extreme LCC.

@ Kaja

I agree. that sounds like a more sensible way to do things.

That would make sense if you had enabled LLC. Try just testing at a low OC or stock with LLC on and off to see what the difference is. It might be the case that the LLC is not configurable enough to be of use on that board.
