Just noticed something: Xeon DP 533fsb has 604 pins, Xeon DP 400fsb has 603 pins: compatibility?

I just noticed this. The "old" Foster and prestonia Xeon's has 603 Pin sockets. The "new" Xeon DP 533fsb chips used in Anand's article has 604 pin Sockets. Does this mean that the new E7505/E7501 boards can only take Socket 604 pin CPUs? Just curious...

There is no such thing as a Socket 604 Xeon processor. If Anand wrote that then he made a mistake, it's socket 603.

This can be checked using this link for comfirmation.

How possible is it to slap two 400mhz Xeon procs into a 533mhz mobo and have it run at 533mhz fsb? Anybody ever successfully achieved this? Just curous

Providing the motherboard permits changing the FSB to 133MHz within the BIOS or via DIP switches then it should work. Otherwise the CPU will still be recognized as a 100MHz FSB CPU.

are you positive?
google.ca tells me otherwise...

i also found "Intel Xeon (Prestonia B) 2.0, 2.4, 2.6 & 2.8Ghz were released on November 18th. These CPUs have a 533Mhz FSB and are manufactured for the Socket 604 platform (previous Xeons used Socket 603)."

Intel would need to confirm this. As far as the actual CPU goes it has 603 pins.

Could be a typing error or a future feature not yet implemented and only available once 604 pin Xeons are released. Present Xeons don't use that pin
having less pins than the socket.

Look back at Anand's article. Look at the pictures of the Xeon DP 533fsb and Xeon MP 400fsb. First off, notice that Anand several times reffers to the Xeon using Socket 604. Now, he could've been misinformed or something, but also look at the picutres of the sockets/cpu's. It is clear in the pics that there is an extra pin near the upper left hand corner of the CPU. This is also demonstrated on the pics of the Socket. But there is clearly some misinfo going around regarding this. I would usually think that Intella would be correct....but, why would Intel give Anand specific Socket/mobo's with an extra pin...he wouldn't. Somebody should ask Intel or Anand to clear this up...

EDIT: Xeon DP 533fsb/Socket 604 page in the review and Xeon MP/Socket 603 socket page

Intel has fantastic documentation on their developer sites. Use them.

Check page 77 of this.

The XEON DP has 603 pins.

The XEON MP has 604 pins.

Andy, look at the pics of the Xeon DP (Prestonia 533fsb) and the Xeon MP (Prestonia 400fsb with 2MB L3 Cache). It's clear in the pics in Anand's review that the Xeon DP 533fsb has an extra pin.

Well, I think I may havew found the answer to this whole question. Go to 2CPU's IWill DP533 (E7505) Preview. Look at the last paragraph on the page I linked to:

I rebooted my machine and I set my multiplier back to 18x in the BIOS. I then booted into Windows to make sure the BIOS settings did indeed work. My Xeons booted at 1800mhz (18x100), and it was time for the moment of truth. A quick shutdown, jumper switch and startup yeilded... Nothing. No POST, no beeps, nada. I thought maybe I was going for too much (although 18x133 would've given me ~2.39ghz from my 2.4ghz Xeons) so I tried again at a multiplier of 17. No love. I'm thinking that you might need socket 604 Xeons to have any luck with the FSB jumper, but since I only have socket 603 Xeons, you're on your own.

That seems to answer the debate. He clearly is acknowledging that there are indeed Socket 603 and Socket 604 Xeon's. It also seems that you can perfectly fine use older 400fsb Socket 603 Xeons in a Xeon DP board.
