How do you upgrade a dell xps T450 processor?

Answer 1

If you know a bit about hardware you could go out and purchase a new motherboard and CPU (you should be able to get an upgrade kit) and then install it yourself by pulling the computer apart and replacing the old one, however if you don't know how to do this then i recommend taking it to an IT professional to do if for you, They will usually give you a warrenty for it and this eliminates the chances of you voiding your existing warrenty so it is definetly worth the extra cost if you don't want to risk it.

If you wish to do it yourself then simply remove all PCI or similar cards from your motherboard, IDE, Sata, etc cables from motherboard and the power, reset light, etc cables. Then unskrew the old motherboard and put in the new one (somtimes you may have to remove the powersupply to be able to get into it.) Then reattach the devices into the new motherboard carful to put it all back into the same places you took them out and follow the motherboard manual if you have any troubles working out what goes where.

After this install the new drivers which came with the motherboard and your good to go ;).

However you cannot just replace the CPU and not the motherboard if the new CPU you have is not compatible with your current motherboard. In most cases when upgrading you need a new motherboard too.
