SOLVED Dell Precision T5500 question

[torin3]

At work we have a Dell Precision T5500 workstation. It had a E5620 quad core in it. Since I was needing to sell off some equipment, I sold my work an X5675 hex core chip for it. We got the 2nd CPU riser board for it, but when I moved the E5620 to it, I got this error screen:



The E5620 has a (HT/QPI) speed of 2933, and the X5675 has a (HT/QPI) of 3200.

(Don't worry about the fan errors, I'm picking up adapters so I can plug fans into the riser fan headers.)

Now I also have an X5670 that I'm not using. It has a (HT/QPI) of 3200, like the X5675. If I put the X5670 in with the X5675, will they work together in this system?

Anybody?

The answer is no, it halts in the BIOS.

Just to finish this off. Works fine with 2 X5650s.

all dual CPU motherboards that i know require 2 of the exact same model CPU.
