CPU swap

Well... we need to know your motherboard to check compatibility of the X4 630 but guessing that the X6 1100T is supported, the X4 630 will be at a minimum supported with a BIOS update.

its a different computer since im getting a 1100t on my main computer i want to drop my 630 in my old acer its motherboard is a acer f690gvm

it seems unlikely

What is your ACER system number (model number for complete PC)?

i believe m1100 http://support.acer.com/acerpanam/desktop/0000/Acer/Asp...

what happens if i just try to fit it in?

No harm in trying to get it to fit... Just don't force it to fit  

If your lucky, it'll boot without issues or it won't boot at all with no harm no foul. Worse case... it damages the CPU (very unlikely though   ).

lol i read that since its a oem board likely there is no bios to update can i ask you a question though my new mb on my new computer says ill have to update the bios should i do that right now is there any bad chance of anything happening when i do?

Typically, BIOS flashing is straight forward, as long as you follow the requirements for your motherboard manufacturer. I only recommend flashing through the BIOS... DO NOT use a Windows based program.

thanks man or woman lol

Man... But thanks
