This is a genuine Dell motherboard.
This motherboard has been thoroughly tested by our experienced technicians and is guaranteed to work in your Dell OptiPlex 755 mini tower.
I ordered the correct board after calling Discount. They knew exactly where to have me look for the board version. The board arrived, and I changed it out in about 10 minutes, and everything is fine. My annoyance is with Microsoft. I had to reinstall windows because they choose to "marry" windows to the old board. Almsot 200 updates later, I was ready to go. It was actually cheaper for me to pay to replace the board, that to have the company fix it under warranty, and pay almost $50 in shipping. I would not hesitate to order more boards from them.
exact match, setup and burn-in went as expected.
Only required swapping the CPU chip. Worked perfectly.
Great service, I had some questions about the correct board to order but one call to the tech team at Discount Electronics and they answered my question. The board arrived quickly, we pretested the board and it tested perfect. Installed it and and my computer is once again up operational and everything is working great and as it should be. All drivers reloaded and no issues or glitches. Nice job, would totally use again when needed.
