nicolo, you have a Asus P5N32-E SLI, E 4300 CPU. 2 kits of Kingston ValueR. DDR2 PC5300 2048MB CL5 Kit w/two matched ValueRAM 1024MB DDR2 , which takes the total to 4 gigs of memory,a Cooler Master Eclipse
"I will be running two Geforce 7800 GT graphics cards, and my PSU is a Seasonic M12 600W, so power should not be a issue either.
Now, the big question:
What settings would you reccomend me to run? I would LOVE to get a complete guide for me, as I don't know too much about how to safely clock my CPU to a stable level.
1: Is it not a good idea to totally cover the CPU in thermal paste?
2: Will it be possible for me to OC my GPU's? They are of different manufacturers, but both have Zalman coolers fitted, should I apply thermal paste to them?"
First, with the E4300, leave the multi at 9x and you can likely run at 350 fsb (3.150 ghz). you will need to set the mb to whats in the page one of my guide and vcore will need to go to at least 1.42.
One problem... your ram. it will likely not have the overhead to handle a decent overclock not to mention mixed sets with different timings so make sure you set the ram to unlinked in the bios (although this may not be enough). with your cooling and that cpu if you take the ram out of the equation you can get very solid overclocks. the ram will be unpredictable though.
you can definitely overclock the video cards. i had a pair of 7800 gts (an asus and a bfg) that I ran overclocked in sli without issue. What OS are you running as vista will have some issues with some versions of ati tool and riva tuner.
the zalman coolers require thermal paste on them over the gpu but dont use the included zalman stuff, its crap, go with as5.
i prefer putting a small bead of as5 on the centre of my cpu and then using a razor blade to carefully smooth a thin, even coat across the entire cpu. Its always worked well although others have different techniques.
