Hello, can you please tell me if the Xeon e3 1230 v6 processor is compatible with the Dell Precision Tower 3620? Have you updated the BIOS to the latest version?
I uploaded the Precision 3620 3420 Tech Guide for you. I have both. The 3420 is the 3620's little brother with much of the same specs. My 3420 is running an E3-1240 V6 not listed in the Tech Guide. There's a chance the 1230 will work, but I don't know for sure.
As for BIOS, the 3620 might be a little old for Dell to release any new BIOS updates. However, the latest BIOS will still be on their site.
I don't know what CPU you have now. So please keep in mind if you update to either mentioned XEON CPU, onboard graphics is lost and a GPU card is required.
