How can I check my pc motherboard whether It can support up to 800Mhz processor?

Answer 1

There is almost always a model number on every motherboard - usually in large letters near the PCI slots. Try searching on the web for this model number. Some programs (shareware CPUz, shareware SiSoft Sandra, Everest) will even tell you what motherboard and model number you have.

Then you can do a search on the web for the "manual" for that model number and see what is supported. Note that very often there is a "rev" number on the board and that will make a big difference on what CPUs and speeds are supported.

Try not to spend more than $150 upgrading your CPU as you can get brand new CPU / motherboard / memory for about that much.

Good Luck

If you know the manufacturer and the model of the motherboard, go to their website under support and view or download the user's manual. If you already have the user's manual, it should be under specifications. Hope you find what your looking for.
