Prime 95 keeps crashing during test

post #1 of 5

Original Post (Click to show)
So I just delidded my 3770k and bumped that baby up to 4.9 it's at 1.47v and while running prime 95 if I try to open my browser it just crashes immediately then after a few minutes prime 95 just crashes, no pc freeze or anything... then i can open my browser just fine with out having to restart the pc or anything, I tried it at 4.8 and 1.41v and it wasn't crashing, it was working just fine... I have no idea why this is happening at 4.9

edit: I just raised the vcore by a hundredth and now the browser isn't crashing at all but p95 will still just autoclose after a few minutes of testing

edit: it seems to have just been a slight lack of vcore because I increased by another hundredth and it has been testing fine

Well I have a peculiar issue, when running prime 95 the voltage stays around 1.48v but then while I was running 3DMARK11 during the graphics tests the voltage was fluctuating around 1.53v sometimes going up to 1.54v but then when it got to the physics test the voltage went back down to 1.48v... Any idea why the vcore is fluctuating like that? I don't really want my voltages above 1.5

what settings do you have in the BIOS?

regardless, i would suggest you lower that vcore to no more than 1.40 for a 24/7 OC.

I've had this CPU for over a year and I don't plan on keeping it forever... I'm aware that keeping it over 1.4v will shorten the life but I'm okay with that.

I just lowered it back to 4.8GHz and 1.43v I'm testing it in p95 now and I'll see if the voltage still freaks out during benchmarks or anything and if it does I'll post the settings that I changed in the BIOS as that will require me going back into the BIOS because I can't remember every setting I changed...

pencil and paper helps to remember settings thumb.gif

just by the looks of it i will guess you have the Load Line Calibration set to medium(?)consider raising it to extreme and that will keep the voltage a bit more steady. however, it will raise the vcore slightly and that may need to be lowered.

Yeah! I knew it had to do with that I just forgot what it was called and I don't remember seeing it on this motherboard anywhere. I'll have to take another look, thanks.
