4GB To 8GB = Hotter CPU?

post #1 of 9
Thread Starter 
After upgrading my memory from 4GB to 8GB, my CPU's load (IntelBurnTest - maximum/7000MB memory used) temps are approximately 10 degrees higher on the two hottest cores, not sure how much higher the other two cores are. Is this normal? Any way to counter-act it without having to buy new hardware?

By the way, my 2500K at 4.6GHz (1.320V or 1.330V, can't recall) is now hitting 90 degrees in InternetBurnTest (maximum/7000MB memory used). Is this safe?

Any chance you bumped or pressed against the heatsink when you were installing the new ram modules? My first guess is to try reseating the heatsink.

Well, with that much ram IBT will stress it more, at least on my sistem if I run 4gb max temp will be around 76 while if I do a maximum run (14gb available), it will go up to 83 C.
Did you change the frequency on your ram?

I've tried that numerous times. No effect.

My old 4GB set was 1600 overclocked to 1866. This new set is 1866 overclocked to 2133. I've tried running it at default speeds/voltages, no effect on temps.

I'm actually using a lower VTT and DRAM voltage with this new set than before.

CPU's act funny when you add memory, did you add more dimms or replace the two you were using?

No idea, sorry. Is it really bugging you?
