Hi there, I'm very new to overclocking, but i have read a very extensive guide on another site and the guide on here.

Of course temperature is a big part in overclocking so i went to look at my temperatures. I'm running an AMD 4400+ at stock speed (2.3ghz) with a stock cooler (I will probably buy a decent cooler when I overclock so any suggestions on which are good price performance are welcome - i dont have all the money in the world to spend :p). ASUS PC probe is telling me i have anything between 40-50 degrees when im just surfing the net with a fan speed of 3000RPM and on startup the bios was reading 51 degrees. Here is where i get confused. These temps seemed high to me so i downloaded everest and coretemp. Everest was telling me 5 degrees which i automatically assumed was wrong. CoreTemp was telling me 15-20 degrees on both cores. Which one do i believe? How can they de so different?

I also have some questions about overclocking:

I am confused as to where RAM comes into CPU overclocking, the OCUK guide talks about the RAM divider, but I didnt quite understand it.

The guide says "Decrease the RAM divider if required to keep it at stock or less" what does this mean? What do I actually need to do?

I'm not looking to OC now (got exams :D) but i will be looking to in a couple of weeks or over the summer hols. I just want to make sure i totally know what I'm doing before I attempt ANYTHING.

Thanks for your help - be nice to me :D.

How do i know what my RAM can take. Say i try to overclock to ~ 2.8ghz (my CPU multiplier is fixed at 11.5) thats around 240mhz main clock, obviously i go in stages to see if i can make this, but would my RAM take that?

Also, any ideas on my temps?
 
Ah ok i think i get it now thanks guys! Well, my RAM is supposed to run at 1.9 to 2.3V and its running at default 1.8V so bumping up the voltage a little shouldnt be a problem. When i go up in RAM voltage, do i do little jumps or could i jump from 1.8V to 2.0V?

Anyone recommend a decent cooler? Preferably under 20 pounds to handle a moderate overclock.

so basically i OC my CPU and then test using memtest86. If there is instability i up the voltage (obviously not past 2.3V). Should i up it to 2.0V to start with anyway? As 1.8 is below the optimum range. Also do i need to test memory stability during CPU overclocking or can i just OC the CPU, then test memory stability?

Sorry for all the noobish questions but i just dont wanna make any mistakes and break or fry something lol.
