Exciting isn't it?
Well, I hope you enjoy your overclocking adventure and if you experience any bumps, we'll help.
So far, great start! Those are unusually low temps for a Prescott. You can thank your wonderful Zalman for that.
Also looks like your cooling scheme is good to go.
Well, I would have told you to check the average OC for your CPU, but Cpudatabase
is down for maintenance. No worries, though. Your 'scott should be able handle a 400-500MHz speed bump.
Another thing you should get into is your BIOS. Study it well. Get comfortable with it. Know what each setting does (well, you don't really have to, but it's good to know) so that if you kink anything, you know what to look for. If you already know your BIOS, great!
Then, you know you'll have to play with dividers for now. As you probably already know that Value RAM isn't prime for OC'ing and won't handle the desired FSB of at least 229MHz in a 1:1 - CPU (FSB):DRAM - ratio. By my calculations, you should be fine with a 6:5 ratio, which would give the RAM about 33MHz of headroom (200 / 6 = 33.33333, 33.3333 x 5 = 166.6667MHz @ stock 200MHz FSB).
I have no experience at all with Intel Motherboards or MSI motherboards, but I think you should be able to find the dividers easily. If not, I guess One4 could help.
Anyway, once you get to them, employ the 6:5 dividers. If you can't find the certain dividers, try 5:4 and so on.
The procedure is pretty simple. With your new dividers now set, bump the CPU FSB 5MHz at a time. At every step, load your CPU to ensure total system stability. Programs like Prime95
Right now, I don't think you should go any further than a 215MHz FSB, to keep yourself in suspense for your Corsair XMS RAM. That is, unless you don't want to splurg on new RAM.
I'll leave the voltage factor up to the pros - One4, Chums, and friends.
