need overclocking advice

temps are cpu 41c and sytem 39c under load

I read it and I went to the links, They were very helpful, and I bought my power supply because your list recommended it.

However, Im running an asus and a pentium d 945. The article doesn't have any pics about my bios, and Im starting way past when the article was written.

Im starting with an fsb of 920. if I change it to 921 windows wont start?
I can only get windows to run if I use the auto overclocking features. 5,10,15, and 20%. 20% isnt currently stable with mem at 5,5,5,5 windows locks up.

I changed the memory times from auto(20's) to 5,5,5,5, auto(21) this matches the rams recommendations. But is it optimal. When I change to 4,4,4,4 it will not boot. I read all the articles and figured out where in my bios to change the ram timings, but not what it was actually doing. Like should I change one and not the other 3???

voltage I had two options I think they were 1.4 and 1.5 I left it on the lower.

Im pretty good at understanding this stuff (normal). However, my bios isnt even remotely close to the one in the example.

I am very grateful to the sticky's and the help I have recieved here. Two weeks ago I didn't even know you could buy anything other then oem machines. Now I have a custom machine running better then any oem I've had. Will go c2d soon but want to practice on the pentium
