I have searched through the HP site and this forum for information on compatible processors for the Z400 workstation. I have found lists and posts of compatible Xeon processors for the 6 DIMM motherboard: W3520, W3550, W3565, W3580, W3670, W3680 and W3690. But the W3530 is not mentioned.
I am confused why the W3530 is not listed as a compatible processor when a search of the Z400 results in hundreds of results of Z400 workstation configured with this processor. it's even listed on this link:
So can anybody confirm whether the Xeon W3530 2.8 Ghz Quad Core processor will work with my Z400, 6 DIMM motherboard as I have one available but do want to risk damage to the motherboard and/or processor.
