I have: Gigabyte 7n400 pro2 512 mb RAM MicroFlow II fan 4000 rpm Barton 2500+ I have overclocked a little bit on 2000mhz (it was on 1833mhz) and i think my temp. is 2 high its around 56°C/133° ( I haven't rise voltage it is still 1.65) is that normal and how much can I go further? Thanks for all your help

56 is kinda high....not extremely high but ON THE BORDERLINE so I would suggest you take care of that first....temps for your processor should be anywhere in between 40-50 comfortably...and when you wanna go further tinkering with a few settings like FSB, multiplier, and vcore SLOWLY would get you a bit further..... take care of the temps before you go any further TO THE DEATH....KA PLA!!

It's either your heatsink is not seated properly or the heatsink is not up for the work load. Another possibility is your mobo is over reporting temps, you can verify this by touching the heatsink when the machine is on.

Touching the heatsink while the computer is on is NOT a good idea. Get it up to full temp, shutdown, unplug, THEN touch it...have the side panel screws taken out beforehand so that it can be removed quickly. Many have been able to overclock the 2500+ to 3200+ by simply raising the FSB from 166 to 200, without raising the CPU voltage (vcore). You'll need PC3200 RAM...

I recently got a 2500+ Locked and i OC'ed to 3200+ using Asus a7n8x-E with 512mb kingston pc3200 in sigle channel mode and it worked da vcore is 1.65 and vdimm is 1.7. the problem is in winXP is boots up but i get program errors that cant run or files that dont open. my temp is 45 idel and 54 loaded.
