Any interest or info on odd Pentium 4s

[i845pe@800+MHZ]

Hey guys. I'm new here.

I am looking at upgrading my 845pe based system and found some rather strange prescott based P4s out there.

Using intels spec finder a few oddities showed up. The first is the 2.26Ghz with only 512k cashe, SL7D7. Its the only desktop prescott (possibly any prescott) with only 512k, and I can't seem to find one for sale anywhere.

Another one I have a question about is the 2.8GHZ 533mhz FSB chip. It is the SL8JX which according to intel's web site is a socket 478 processor, and the database here at cpu world claims it is 775. Since I can't seem to find one of these for sale, I don't know which it correct. The reason this CPU caught my attention in the first place is the G1 stepping, which would make this CPU the slowest G1 for socket 478 and would make a great overclocker for my 845pe system.

Any info about either of these and any people collecting Pentium 4s would be of interest to me.

You're right about SL7D7. It is rare chip.
SL8JX is Socket 478. There is a mistake in cpu-world's database :
- if you look here it is LGA-775 : http://www.cpu-world.com/sspec/SL/SL8JX.html
- but if you look here, it is socket 478 :

Thank you very much!

And now for one more I dug up. How about the 2.4ghz 533mhz fsb HT prescott SL7FY. If intel is right about the fsb speed, this would be a strange cpu. CPU World says it is an 800mhz fsb which is not so odd, but still not common.

You can also check out the mobile P4 with FSB-533 and HT with 1MB L2

Has this SL8JX featured the NX/XD bit for installing Win10???

Possible for a socket478 really???
