So, I've been running 3 Sapphire 7950's for quite some time now, and one of them just burned out. I went and picked up a R9 270x, and I can't get my pc to even recognize it. I actually went and picked up another one just to see if I maybe had a bad card, and the second one is the same as the first, a no show! Am I doing something wrong, or have I gotten 2 DOA cards in a row?
Any help would be greatly appreciated!!

standard troubleshooting procedures:
Card not recognized? 2 hardware possibilities: bad card or bad slot
You've checked the card, now check the slot.
plug that "new" card into a different slot and see if it works. If so, then you may have burned out your PCIe slot.
Is your PSU supplying enough power to your cards? most PSUs only supply a certain amount of power PER RAIL, so you need to find out how you're powering your PCIe cards. MOST PSU's with multi rails will have the mb connectors on one, Molex on another, and PCIe on another one. Some ahve 2 rails each w/ PCIe connectors. If you overload a rail, it won't supply enough power, and the card will try to draw power throughthe PCIe slot and burn it out.
Also, most PSUs are not designed for 3 graphics cards.

Thanks for the suggestions! I have tried moving the card around to different slots, and they all work because I've run the other two cards in the other slots. I did try running just the new card by itself, but the other two cards were still plugged into the PSU. I will try running it alone once and see what happens.

Ok, so tried both cards in all 3 slots, and tried with just this card on PSU, and still no detection! This sucks!! Could it be that I just happened to get 2 DOA cards in a row?

mhe im a say highly unlikely did your other working cards work in the last slot we think might be bad? if so then yes it seems you are unlucky enough to get 2 bad cards.

If it's a newer mobo I've had problems with PCIe Gen 3 slots. Drove me nuts because it worked with one 7950 but not another (only to find out one of the 7950s was infact dead).
Try going into the BIOS with a good card and set to Gen2, or maybe update the BIOS.

Did you update your drivers? R9 cards require a newer catalyst driver. The one you were using for 7950 won't recognize it unless you've updated to latest versions.
Is this on windows or linux?

I've tried to update the drivers, but it says that I have the latest one installed already. When I put the disk in, it won't even let me instal drivers from it. It gives me a message saying to go to AMD.com to get the latest drivers, and there it tells me I have the newest one. The problem is that It's not even seeing the card at all. I have tried the two working cards in all 3 slots, and they all work. Even tried a different PSU just for the two cards that don't work, and still nothing. The fans run on both of the cards if that means anything. Gonna go pick up a third card today and see what happens, but before I do, I will try what DrG said. |

You can always install the driver. It's best to remove the one you have first though. |

I'm surprised that the computer isn't finding the new hardware when I start it up with the new card. |
