Default OCing Dell Dimension 4600

K, I've decided to OC this computer. It's only got 512mb of RAM and P4 @ 2.79. What's a good temp. reader that I can get? How much do you think I can OC this machine to? And..how do I OC?

I may be mistaken but don't DELL lock the BIOS so that it can't be overclocked. If I am mistaken, then a good temp reader is PC Wizard 2008.

no. the bios is locked and there is no way that i know of to unlock it. i have searched myself, but i don't believe you can unlock the locked bios on the dell boards. i wish you could though.

Dells are simply not made for over clocking. The bios is hard coded that way.

Ok..this is what I found on google. It says it's still possible but I'm not expert at this, I don't know what anything means.

Step 1) Check to see if the Dell uses the ICS 952601 PLL. See either:
http://www.podien.onlinehome.de/FSB.HTM
http://mitglied.lycos.de/podien/FSB.HTM
for more information.

Step 2) Download and install cpucool available from:
http://www.podien.onlinehome.de/CPUCOOL.HTM
http://mitglied.lycos.de/podien/CPUCOOL.HTM

Step 3) Run cpucool and go to Functions->Change front side bus/change CPU speed

Step 4) Under PLL manufacturer, pick ICS and under PLL type, choose 952607

Step 5) Click on the Fine tuning button

Step 6) Adjust the Frequency using the buttons at the top and adjust to a reasonable overclock value.

Step 7) Hit Freq Set and the system will be overclocked immeadiately. However, not all programs will register it, but CPU-Z and benchmarks that don't rely on processor cycles will show it.

Step 8) Reboot, and then all programs will recognize the new speeds



what do you guys think?
