Cpu info

Is it actually blocking you from installing the software?

You can find out CPU information on wiki or intel sites. http://ark.intel.com/?iid=subhdr+prodlook_prodspec

everything installs but saids cpu doesn't meet requirements needs to be upgrade to d541 or higher.I thought d640 was as good as d541

I think you have some wrong info.. .or I do.
The 541 is a single core hyper threaded processor and not a dual core. So no D in its name.
The P4 640 is not a dual core either but does have hyperthreading also. It has 2Mb of l2 cache instead of 1 that the 541 has.

I see no other difference myself. Thats a strange problem you have.

I found thier spec page and the 40 is not on their processor list.

If everything is running aside from the message at setup, ignore it. Although it's a bit odd that it lists a version of the chip instead of just saying how fast of a chip you want.
