Precision T7400 RW199 Motherboard

This question is not answered

Question: does the RW199 motherboard support intel 5000X chipset processors?  The RW199 has the intel 5400 chipset which does officially support chips from the previous generation 5000X (in particular the Xeon 51xx and 53xx CPUs).  My question is more-or-less about Dell's due-diligence with respect to writing complete BIOSes.  Simply put, can I buy an RW199 mobo and put an X5355 in it?

  • Dear Chris, 

    Thanks for the response.  The list above is the list of the 52xx and 54xx xeons, the generation of Xeons which require the intel 5400 chipset.  I am suspicious that this list is not exhaustive, and that it is just the stock answer that Dell's marketing strategy puts out.  Can you confirm that this list is exhaustive?  According to intel the 5400 chipset is compatible with 51xx,52xx,53xx,54xx Xeon chips of all flavors.


  • I just setup a T7400 with Xeon X5355 and it seems to work just fine (Ubuntu 10.04) except for a pesky message from the BIOS stating that the processor is not supported.  As far as I can tell, despite Dell's best efforts to block the modularity of their hardware, this works perfectly well.
