10c temp difference across the cores?

post #1 of 7
Thread Starter 
So I have my i5 oc'd to 4.5 on 1.4v, and as I'm stress testing (as I type this actually) I notice that core 0 remains aropund 53c, cores 1 and 3 around 57 and core 2 sits at about 63. Is it normal for there to be this much of a difference between the temps?

Also, I set the voltage to 1.4, but cpu-z is saying its 1.328, though when I'm not stress testing it says 1.4. Whats up with that?

thanks!

Its normal, you can try to seat it better and check your thermal paste spread, but again pretty typical.

Make sure you have Line load calibration on for the board to avoid vdroop, you might have to play around with which one works the best if yours has multiple settings.

Id like to know as well. Mine idle at all different temps ranging from 36c-43c.

Vdroop on the CPU? And regarding the temp sensor it may be normal but I would re-seat the CPU and see if it changes anything. My 6th core for some reason says it idles around 53C which is 10+C from the other cores, but under load it's within 4-5C so it seems fine.

Perfectly normal, however, a reseat may help.

It's nothing to worry about. I have an i7 that does the same thing

thanks!
The voltage drop is called vdroop. It happens when you put a load on the CPU. If you're stable then I wouldn't be concerned. If you want your vcore to drop when not being stressed you need to enable EIST and C-States in the bios. They don't need to be disabled with SB chips.

Awesome, thanks guys! I think I have a winner at 4.5ghz @ 1.4v, we shall see.
