Closed 5870 and Asus PN5-e SLI? Tags: Radeon Asus SLI Motherboards Graphics Last response: August 31, 2012 7:03 PM in Graphics & Displays Share seamus_ar August 31, 2012 4:22:23 PM A question for the community, please. I am upgrading from an Asus 6870 to a 7950. My plan was to give the 6870 to my wife, who is currently running a 4870. Her motherboard is an Asus PN5-e SLI. Installing the 6870 in her system results in no POST and the error code of one long beep and three short beeps. The 6870 still works in my system, and the 4870 still works fine in hers. I have swapped power supplies to very there is no power issue on either side. The PN5-e SLI is at BIOS version 1406, which appears to be the latest. Googling appears to show other people having a similar issue with this motherboard and modern Radeons. Any suggestions, or give it up for a lost cause? Thanks, everyone! All input appreciated!
