Before I add the E5-1660, I will first test the E5-1620 that came with this motherboard.
The idea is to see it post, run it for a few days, and then make the original upgrade I had originally planned.
Originally, I had an E5-1650 in the other motherboard. Things didn't go so well -A mix of what may have been discovery of liquid metal (likely something else) and myself bending the pins trying to clean it out.
This is how we ended up with this "new" motherboard with CPU.
In this instance, this small nick (chip), that is too small to visually see, is on the outside board of the CPU board and generally should have no impact.
