Greetings,
(H61m) This chipset was released during the transitions from PCIe 2.0 > 3.0. Sandybridge to Ivybridge. The non B3 version (yours) should support PCIe 3.0 spec cards.
Your CPU however, is PCIe 2.0 capable only. While a new BIOS rev should give you backwards PCIe compatibility, this is not always the case based on what we've seen from other users here.
Recommend CLR_CMOS (which you did)
Remove and reseat card
Ensure you have Aux power connected
Ensure correct BIOS settings (Disable On-board)
Change Gen Modes from AUTO to Gen2 if available in your BIOS rev
Are you sure that CX500 has enough Amps on the 12v rail to run the card? May want to look into that.
Thanks for the reply.
I've tried all the options you've mentioned and still nothing. I tired PEG1,2,3, Auto, disabled on board, etc.
I previously ran AMD Readon HD 7850 on this build fine without needing any modification in BIOS. It died a few months ago, therefore I was looking for only a GPU upgrade.
I believe HD 7850 was also PCIe 3.0.
One more thing, after I reassembled the board is no longer detecting one of the RAM. Weird. It was working fine.
Seems like the board is dying.
I will have the local vendor guys check it up.
If all else fails, looks like I will need to upgrade.
Thanks
