Hello All

Does anyone know of a complete CPU compatibility list for the Dell Precision T7400 (possible quite an early model)? I've managed to find one for the T7500 (a technical guide) but I can't find the same for the T7400. I am begining to suspect the issues I have in getting a barebones T7400 up and running may be due to a BIOS incompatibility. Unfortunately as I can't get the system to boot (it immediately shuts down with no video) I can't tell what the current BIOS version is.

The chips I have tried are:

Xeon X5472 (3GHz)

Xeon E5345

but the chassis won't boot. It could still be a total motherboard failure but everything else (RAM, PSU) has been swapped out to no avail.

I'm wondering if I purchase the lowest specification compatible CPU, get the chassis running and then update the BIOS I could then upgrade to one of the above CPUs.

Any assistance that can be given would be greatly appreciated. Thanks in advance.

Regards,

Anthony
