Hi, I have z420 (618263-002 REV 0P) with Xeon E5-1680 V2 and 128GB of RAM, it was working well until white smoke came from motherboard. I noticed one broken trace from PL601, I soldered it back and everything is working fine, but rear fan is not detected, so I decided to replace the motherboard.
I accidentally bought 618263-001 REV 0C with Xeon E5-1603 and it's working, but when I put my CPU it, it's not posting. After pressing power button it looks good for a moment, but instead of seeing post, fans are going full speed and nothing is displayed.
Is there a way to use this motherboard with this CPU and memory?

The answer to your question is no. You have a v1 motherboard there that cannot reliably run any v2 processor.
You need a version 2 Z420 motherboard. When buying from eBay the pictures in the ad often show a motherboard's bar code label. The numbers on the left won't help you for this question. The number on the right is the key. I've posted on exactly that issue, but you'll have to look up the answer because there are quite a few HP workstations with version 1 and 2 for different reasons and different numbers you need to have to ensure you buy a v2 motherboard. I just can't remember all that, but do have my notes, and you should be able to find the answer yourself via google/bing.
