hey beat!

 

i also have an powedge 1400sc with 2 x 1ghz processor..

my bios is a09 as well

i also have 2 1266 tualatins here but the poweredge doesn''t boot up with them..

not even with one tualatin..not with a lin lin convertor either

i think it's a vrm item..or a revision version of your motherboard (mine has rev 0.8)

my netfinity 3500m20 (IBM) accepts at just one tualatin with the lin lin  convertor

but the poweredge doesn't do anything :((  

 

mine experience with my  powerdge is that he accepts the IBM netfinity VRM, and he swallows compaq memory

by the way.. i wanted to replace his noisy fan with an dell gx1 optiplex fan (they have the same connectors) but the optiplex fan burned out !!

 

but anyway... i think you should look to your rev number of your mboard and to the vrm partnumber

 

good luck!

 

 

Thanks for the reply. from what I have been able to determine by reading Dell documentation.

 

The 800 MHz through 1 GHz processors use one type of VRM model (I don't heve the Dell part number at this laptop) and the > 1 GHz processors use another (differnet) VRM module.

 

Since I recieved so little information from Dell sources, we will not be upgrading this Dell server to dual processors -- we'll look to other mfg. for solution.

For the PE1400 to support the Tualatin processor's you must a have systemboard 1H734.  If you PM me your service tag I can tell you for sure.
