I would like to state that I'm new to overclocking so, please bare with me.

I'm currently having some slight trouble with my overclock. Before I state my problem, I would like to request some specific information from you fellow overclockers. I would like to know all your voltage settings, the exact number of your FSB and multiplier, and your mobo(please state model number and chispet).

Currently I'm having freezing(yes, my pc actually froze, last time I had a freezing problem was from my AMD Athlon XP 2600+, my pc never froze when I overclocked my X6800 to 3.6) problems with my computer when I'm at full load(by prime95). I'm guessing this is because of an unstable overclock, I'm not too sure; it would be nice if someone can tell me if the overclock is causing that problem. It actually froze on me once when I was playing Counter Strike Source(which only use at 40% of my cpu max) for more than half an hour. Every other time was from Prime95.

My overclock set up is 440 x 8 at cpu voltage 1.45v(BIOS), 1.416-1.424(CPU-Z, it flickers between those "two" number randomly), and around 1.375(I think that's the exact number) full load(CPU-Z). Every other voltage setting is currently at auto. I would also like to mention that this setup survived prime95 for a little over an hour, but after that test, it can't survive more than a few minute of stress testing from prime95.

I also have some question on my temperature, just want to make sure if it's too hot or not and which temperature reading is correct. I've used three different program to detect my temperature and all three displayed different temperature from one another. Those three programs are coretemp, realtemp, and speedfan. The reading I'm about to give are all idle temperatures if you want to know the load temperature, just add 10-18c to the temperatures there. By the way, these are the latest version of the programs. Here are my readings:
Realtemp
core 0: 33c core 1: 36c core 2: 39c core 3: 39c
Speedfan
core 0: 38c core 1: 41c core 2: 44c core 3: 44c
Coretemp
core 0: 43c core 1: 46c core 2: 49c core 3: 49c
The TJ max for all of them are 105c except for speedfan since it doesn't list the TJ max. If you look at the numbers carefully, from core 0 and onward, the temperatures increase by 5 except for core 2 and 3. Also, between the three reading, there's a 5 degree difference. So, which one has the correct reading and is my processor having proper temperature and is it considered cool? Also, it would be nice if someone can tell me what exactly is TJ max.

Thank you very much in advance for reading my ridiculous long post.
