Any way to improve my system?

[Appledrop]

Hi, just wondering if theres anything i can do to tune my pc for a lil more performance , not that its slow - i just like it to be faaast

Anyway; heres my "rig"

p4 2.26b at 2550mhz (150fsb) at 1.4 volts [stock hs/f] [my motherboard undervolts it from recommended 1.525, but i can up it in bios if needs be -dont want to damage proc though]
2xcrucial pc2100 256m ram (512mb, DUAL CHANNEL - 4200gb/s - but fsb 150 - so 4800gb/s)
MSI GNB MAX 2-L mobo
generic 300watt psu
a mystery black case from a premade Europc computer (- side off for cheap cooling )
2x old maxtor 5400 rpm hdds - not want to change hardrives..
and umm a geforce 2 gts ultra - (sold my 9700p )

ok, wellll, i would like to improve my overclock perhaps, without buying new cooling - atm im 50 degrees idle, would accept anything up to 60 degrees idle.

Also, i dont really understand about the ram timings - in my bios it says the CAS is 1.5, but CPU-Z says its 2.5.. sooo, what can i do

the following might give you free performance: (do at own risk)
1. overclocking
2. Update all your drivers to latest version
3.bios optimization
4. disable uneeded services
5. play around with TuneXP
6. remove any spyware you might have

well if you want a speed boost in games try buying a new graphics card like an ATI 9800 pro they are cheap at the mo.

I know you said you did not want to but... if you want to speed up windows try a new hard drive a 7200rpm one, it will speed up loading windows and loading game maps.

1. Defrag the hard drives (I would get a 7200 drive, the 5400 are slow as a boot drive)
2. Remove spyware
3. Scan the hard drive for viruses
4. Disable unneeded services

Or spend money...

You can lap the heatsink with some 300-400 grit sandpaper to get a good surface to contact the chip, assuming you have some sand paper and thermal paste on hand. Build a duct out of cardboard to your rear vent that fits over your chip's heat sink. Should cool it enough to let you put the side of the case back on.
