Should i oc

The computer Iam thinking about overclocking is an old compaq presario. I dont know the exact specs but heres some:
AMD-kb-2 processor I think its somewhere under 300mhz
4mb 100mhz SGRAM
133mhz 2x AGP 3d graphics
3gig or under hd
windows 98

Is there any point in overclocking that so it could be usable.
Also i may try and oc a dell thats 4-5 years old depending on results.
specs:
windows xp
pentium3 800mhz
20gig hd
256mb ram
Nvidia 64mb graphics card

How much will i be able to tweak those two sytems?
also specs are not exact since computers are not with me at moment.

 

probably on the dell, but probably not on the compaq...

 

If i do how much will the specs be increased on both

 

And also would it be a good idea just to practice on the compaq or would the old parts just get messed up?

 

If its socket 7 i say get a K6-3+ ( if you can find one ) other then that youl need to take it apart and fish for jumpers / dip switches and even then youl be lucky to get a 50MHz OC....

 

Ive got a socket 7 laying around that im pretty sure works... Its an intel though.. I know its a Pentium but i think its a P3... might not be though.

 

If i try overclocking will i be able to set it back to normal shortly afterwords and make sure nothing goes wrong? heres specs for it
xp sp2
p4 3gig
Intel 82865G Graphics Controller
512 Mb ram
...

 

if you CAN go into the BIOS and change it, just remember waht it was at stock and you can do it.

 

The computer is a new one so probably not will that affect anything?

 

It wont affect anything, just be sure to check your temps... download something like Motherboard monitor aka MBM5 unless you have another program to keep watch on your temps..

If you havent, and your a first time overclocker... I RECOMMEND you read it.

 

I got about 75% down it. Just thought id ask a few questions about it while i finish it

 

get new computers man... dells are a bitch to OC anyhow

 

not nessicarily... if you manage to get into your Dells BIOS, you should be able to disable something called "quickboot" which only shows the Dell logo, instead of your system specs. Then youll have a better chance of getting into your BIOS.
