The "J" series P4s feature Execute Disable Bit techology.

It's hardware protection against some worms, viruses, etc.

Ehhh...

No.

It actually stands for the socket. "J" processors are socket 775.

XD and 64-bit exentions I believe...which are 775 only.

well all 5series are 775 and only 5x1 models have 64bit
XD seems to be the only difference

Thanks

I've seen 5xx skt 478s before. 6xx series is 775 only i thought. i dunno. It confuses the crap out of me...

That's funny. Intel's sockets even baffle the techs. I can only imagine what the common man thinks when he hears one of these CPU names.

*Edit* Maybe the "J" stands for "J-Lo Edition", and they come with a special fragrance that you can spray on your CPU. :Q

The P4 3.2 and the 540 are pretty much the same cpu as far as I know, the only difference being the first is s478 and the second is lga775.
The s478 model was never marketed as 5xx, if you saw a s478 called 5xx that was most probably the retailer calling it so, perhaps in an attempt to make it easier for customers to choose ? (if both cpus are 540 the customer has only to choose the socket).

Here is a model table:

P4 xx speed - s478 cpus
P4 5xx/6xx - 775 single cores
P4 8xx - 775 dual cores

The second number usually denotes the speed, 2 is for 2.8ghz, 3 for 3.0, 4 for 3.2 etc etc
This can be helpful as a model number can say more about a cpu than just a speed rating (ex: 540 vs 640, same speed diff cache).

The only thing that confused me was the J on the 5series, but now thats clear as well
