Vcore not changing

Rob Turbo · 24 Apr 2013 at 17:31

I noticed today that the CPU temp is higher than usual, it would usually sit around 26c at idle and not go over around 68c under load, but now it's sitting at between 30-40c and got up to 72c after 2 minutes of prime95.

Room temp is about the same as always.

I checked the vcore and it's 1.295v, which is higher than I set it in bios, not by much, it was 1.290v in bios, I restarted and turned the multiplier down by 1 and took the vcore down to 1.250v, saved, back into windows, vcore is still showing as 1.295v in all software that has it, restarted again, vcore down to 1.210v in bios, still no change in windows and temps are still up.

What's going on? Could this be something wrong with the bios? It is a beta version and TBH I didn't check the voltage when I updated to this version, I just put my old settings in and carried on as usual, it wasn't until I noticed the temps that I checked.

Motherboard is a GA-Z77-D3H, CPU is an i5 3570k.

what voltage cpu are you using,fixed or auto or offset

if it wont save the setting you probably need to clear cmos(reset bios settings) or reflash the same bios again and then try

idk if your stock or oc'd? offset is the best imo,cpu set to normal voltage medium llc and maybe +0.010 offset voltage

It's oc'd, was at 4.4ghz, now it's down to 4.3ghz, I was using fixed voltage, it was saving in the bios settings, but it didn't matter what I set it to, all software and even the bios was showing 1.295v

I'll try changing a few settings, if it makes no difference I'll reflash the bios, if that doesn't help I'll try going back to the last non-beta bios.

i have the same issue from time to time with my gigabyte z77 up4 th

the settings wont save,only way to cure it is to clear cmos and/or reflash the bios

Reflashed the bios and all is well again! I think I'll look into using offset rather than fixed voltage, is it the same procedure for overclocking? Keep upping the multiplier until it fails/crashes then add more offset?

Thanks.

yeh,offset adds that little bit of cpu v to your cpu's defualt vid set by intel,llc(loadline calibration) adds a touch more,depending on what level you use

best thing with offset is cpu downclocks in speed/voltage at idle,and switches to full speed/voltage at load

if you need help post back but start with medium llc and +0.010 offset for now,if unstable just add one click more offset so +0.015v and so on till your stable

turn on all powersaving in the bios,it wont affect anything

I tried with the settings you suggested and under load I was getting 1.295v, dropped the offset down to +0.005 and I'm getting 1.280v under load, could probably go lower @ 4.3ghz, I can't remember what voltage I found to be stable, for 4.4ghz I think I'll have to go back up to +0.010, I'll experiment more tomorrow.

if you want to lower even more then change from a + offset to a - offset,then it will take off voltage at load

so maybe -0.05v or -0.010v and so on
