Prescott

[pandreas21]

I have read that some new Prescotts have 64-bit extensions but are locked. I was wondering if there is some known way of enabling this feature through a hardware hack. Also which processors have this "inside"? Thank you

I don't believe you can unlock the 64bit in Prescott.

I think that only when you make the CPU you can choose to enable it or disable it, afterwards it will stay off forever.

I once read that even early Willimate core had Hyper Threading disabled

No there is no current Prescotts with that instruction set. Hardtweak is futile.

Prescotts with 64 bit, are called Athlon A64. They require a socket 754 or 939 board.

There are P4's (I believe based on Prescott core) with 64-bit instructions (Intel's version of AMD's instruction set). As far as I know only Gateway and Dell are able to get them.

Hmm that could explain why I never ran into one, I DONT TOUCH OEMS!!!

However Im going to prod around with my dell contacts of that info.

Check out HP's website, I think they have a couple of single processor "work stations" with EM64T.

After Intel fills the OEM server/workstation market, you might see the 3.2F, 3.4F, and 3.6F hit the streets.
