Just have a couple quick questions. I am looking into overclocking and making sure I understand everything before I get going so I don't ruin any hardware.
Here is my build, it has been running for 1 week now:
Intel i5-750 @ 2.66ghz (stock)
Hyper 212 Plus heatsink
Sapphire Radeon 5850 (stock speed)
Question 1: I have been watching HWMonitor, and have noticed that 2 of my cores like to stay at least 5C warmer than the other. For example, right now at idle:
Core 0: 33
Core 1: 28
Core 2: 33
Core 3: 28
Is this normal? Could my heat sink possibly not be seated properly and slightly leaning or something?
Question 2: I was looking around the BIOS and found an easy overclock, where you choose a speed and it auto sets everything for you. I chose 3.2Ghz, and bumped it up to 3.6, just to see if everything would still post and really to just give it a quick test. Everything booted up, seemed fine, but when I ran Prime95 the CPU temperature went from about 35C to 75C in a matter of 10 seconds or so. Which brings up the question again, could my heatsink possibly be not seated properly? Maybe the setting I chose used wacky voltages and that caused a problem?
Just looking for a heads up before I do the real deal! Thanks.
Edit: Just ran Prime95 for 30 mins (at stock CPU settings) and the highest I saw was 47C, with all cores being within 5C of each other. Does that seem like a pretty normal temperature?
I put on the thermal paste that came with my heatsink (I believe it came with that). I followed what it said on a guide I had read, and put a horizontal line from left to right about half the width of the CPU. Could it be too little, or maybe just needs time to settle in?
