Hello All



I just did a RAM upgrade on my 2011 15" MacBook Pro. I went from 4GB to 8GB. I noticed a slight rise in the CPU temp. I know this may sound ridiculous, but it went from running at aorund 105 degrees fahrenheit to around 122 degrees fahrenheit with only Chrome browser runnning. I'm just wondering if adding RAM can sometimes cause a rise in temps. The RAM I took out was the stock RAM Apple installed which was Samsung. I replaced it with Corsair RAM. When I installed the RAM I ran memtest and everything passed. I realize 122 degrees is not hot, but am just wondering if some RAM runs hotter than other RAM?

Other than the slight temp increase the RAM seems fine. No kernel panics, no freezing, system seems stable. My fans are running around 1999RPM's.
