Hi all,
I recently got 2 Radeon HD 5770 from a friend. I was looking for a new GPU and thought I would try out crossfire with these two 5770s. At first I replaced my 7770 with one of the 5770s. I ran benchmarks before and after I switched, and was surprised to see the performance increase both in-game and benchmark software.
I then tried to install the second 5770 with crossfire. I accidentally plugged in the 6-pin from the card to the MOLEX/SATA/FDD connectors on the PSU instead of PCI-e connection on the PSU. I tried to boot the system, but the BIOS did not recognize the HDD and the optical drive. I tried switching the HDD to every other SATA connection on the motherboard, but the BIOS still doesn't recognize it.
I checked my HDD in friend's computer and it works fine. I connected an SSD without OS to my motherboard, but it still did not show up in the BIOS.

Could I have damaged my SATA ports when I connected my cards 6-pin to a SATA 6-pin on the PSU? Is there anything I could try? Thank you for the help everyone!

Not sure if you could damage the ports, but look in your BIOS. In your BIOS somewhere you should find a lane setting that may say 16x/0x/0x (as an example) Instead you will want to manually change it to 8x/8x/0x (essentially half of the large number). This should do the trick, if not.....

Try swapping positions with the cards. Sometimes simply reseating them does the trick. Other times one card apparently thinks it has to be the Alpha male.

Make sure ALL power headers on both cards have the appropriate cabling attached.

Make sure the cabling into the modular PSU are FULLY inserted and locked in place.

You might also need to fully uninstall the drivers using display driver uninstaller (Use the DDU to uninstall. Uninstalling...

You might also need to fully uninstall the drivers using display driver uninstaller (Use the DDU to uninstall. Uninstalling from Programs and features doesn't always remove relevant registry entries) and reinstall the drivers WITH both cards installed.
