Does 2nd CPU need to be from same lot ?

[comtutor]

Hey fellow techies. I am upgrading a newer Dell Poweredge server to a second CPU ( PIII 600 ) and have heard conflicting views. Lets take a vote. Does the 2nd CPU have to be from the same lot as the first or not?

TIA

What???? I've never heard anything like that, I'm not real familiar with Dell servers but if thats the case I would throw that thing out the nearest window! I think what they mean is you can't install a PIII 600 running at 100Mhz bus speed with say a 600B that runs at 133Mhz bus speed, or a 600E which is a Socket 370 chip, as for the same lot number....like the next serial number from the factory? I know this to be the case when buying wall paper or paint, so you don't have a darker shade than another &quot;lot number&quot;.

Hi Draq,

well what little i understand is they are refering to the steping number and revision number. and it has to do with the CPU's specs, ie there are slight differences between the batch's like a spread of the CPU's specifications. now most suppliers advise that you need to specify that you want n number of cpu's to go in a multi processor machine this is not a dell specific thing. check out the intel site for more info.

also some of the &quot;CPU clocking&quot; sites have a lot of info on this, they are mad, but in a nice way!

I think this was a real issue with first gen pentiums which had to be ordered specifically for dual configuration.
I just upgraded three Dells P-III 500s to dual with no problems. I had called my CPU supplier who told me that it shouldn't be an issue. [sig]<p>Al<br><a href=mailto: atc-computing@home.com> atc-computing@home.com</a><br><a href= > </a><br> [/sig]

No it does not have to be from the same lot. If you do have a problem with the server seeing the 2nd processor, try running uptomp.exe, this can be found in the resourse kit. Please refer to Q124541
