I installed my Sapphire Vapor-X R9 290 this week however I've been having problems with it.
I have the card hooked up to the PCI Express 6 pin cables using the additional 2 pins which hang off the original connector. The card takes 2 8 pins total. I think the extra two pins can only be inserted in the right most 2 pins and not the left most.
The card is performing slowly. I am also confused by the UEFI button on the card. I've uninstalled my previous drivers and updated to 14.4 beta. I am running the card on a Corsair TX850 and Gigabyte GA-Z87X-UD5H alongside a i7-4770k which had been overclocked, but then I returned it to stock hoping that was my issue. It wasn't. The card interacts with the UEFI bios in an odd way. Its almost as if alot of handshaking goes one before the card goes to windows....based on if the UEFI button has changed recently.
I've done an AVP benchmark and only recorded 20fps @ 1920*1080 max settings. That was with the UEFI button off. With the UEFI button on I was getting better results at maybe 70fps. However, I should be getting ~ 95fps.
Desktop composition is also slow. Sometimes on boot the rendering of the windows boot logo is frame by frame until the login screen where the speed increases but its still not the silky smooth I should get and sometimes get with the UEFI button.
I'm almost thinking this is a bios issues, that or my PSU is not good enough for this card.
Any ideas?
