Hi guys..

I've been able to overclock my AXP 2400+ to only 2.1GHz, but I've been reading about how high these processors OC (average of aropund 2.2GHz with stock cooling). I've tried to OC it by upping the FSB to around 146 (default FSB is 133) and it's pretty unstable. I was thinking that it might be possible to increase stability by upping the core voltage of the CPU (currently at 1.664V), but I'm not sure how it's done.

I've entered the BIOS and looked around and found this:

CPU Voltage Regulator

Normal
+25mV
+50mV
+75mV

... with Normal selected by default.

How does increasing the CPU voltage work? Do I use those options above to select the voltage? :confused:

I'd appreciate any help you guys can give. Thanks!! :D

Upping the CPU voltage just helps drive the FSB to higher levels. You are going to have to OC your RAM too. The unstablity is due to the RAM and FSB clocks being way out of sync. There is a good FAQ here for OCing your CPU: http://www.hardforum.com/showthread.php?t=795444

Be very careful OCing your memory. Driving 2.9V+ to the memory will really hurt its longevity and possibly even fry it. I hope I been some help and good luck OCing :)

In most cases if you want to get high over clocks on that XP2400 then you will need to up the voltage,The Xp 2400 that I have will do 11x200 easy with the cpu at 1.7v but it is a older one.If you were going to run a XP it best to get the mobile the XP Barton 2600 that I have will do 12.5 x200 2.5gigs with the voltage set at 1.775v.Is your XP2400 multipler unlocked if it is then set it to 11 and the fsb to 200 and raise your voltage with that +50mv.
