Second PCIe slot can be used for a Raid Card?

[checco007]

Hi Everyone,

I would like to know if the second slot of the GA-MA790GPT-UD3H can be used for a LSI Raid card. The card is an x4. 

I did try to contact Gigabyte but apparently they forgot to answer me. 

Thank you for your help

Hi,

I might be wrong but I believe that you should be able to run the Raid card in the second slot as PCIe is backwards compatible.

However, if you are using a Graphics card in the 1st PCIe slot you might notice some graphics issues, as the bandwidth will drop to 8x's rather than the 16x's that it runs at if only 1 PCIe card is used as the 2 slots share bandwidth when they are both used.

If you are only using the on-board graphics then I don't think you should have a problem.
