I am upgrading my Intel DP55SB with a Gigabyte GTX 760 2GB video card. After adding the new card, my system no longer posts, and beeps 2x indicating a video problem. I performed all the standard troubleshooting: reseat card, verify power connections, etc. Also, I made sure to connect an additional sata power cable to the motherboard header per the instructions manual, as required when using a PCIe card with power requirements over 75w.
My system specs:
Intel DP55SB, bios KG5926C.BIO
Intel Lynnfield 2.8Ghz
G.Skill Ripjaw 4Gb 2x2GB
Enermax Modu82+ 625W
Samsung 128GB SSD
Generic DVD ROM drive
My question: is the Intel DP55SB compatible with this video card?5SB
Thank you for any help or info you can provide.
Following up on this myself:
I updated my BIOS to KG5936P and video card now work great.
