My [COLOR=blue ! important][COLOR=blue ! important]system[/COLOR][/COLOR]
includes an eVGA P55 SLI mobo and 2 SLI'd 9800 [COLOR=blue ! important][COLOR=blue ! important]GTX[/COLOR][/COLOR]
+ video cards. I decided to upgrade the coolers as they run hot under load and I wanted to do some overclocking as well.
I'm using a pair of Accelero Twin Turbos which work awesome, silent and about a 20-30 degree drop, however, the cards will not fit in my PCI-e x16 and x8 slots due to the thickness. Currently, I am only running one because of this.
I ordered a PCI-e extension ribbon cable which allows me to plug the male end up into the PCI-e x8 slot in the board with just enough clearance behind the fan shrouds and allowed me to relocate the 2nd card. Success?
Nope. The motherboard does not recognize the card through the extension. There is no display, no recognition in the device [COLOR=blue ! important][COLOR=blue ! important]manager[/COLOR][/COLOR]
, and when used to connect the first card to the motherboard, the LED readout shows a 2e code indicating no graphics card. Here are the steps I've taken:
Put the 2nd card in the PCI-e x4 slot below, but I was informed that you can not use this for SLI, it is dedicated for only a 3rd card for PhysX.
Uninstalled and reinstalled the latest versions of the drivers.
Ordered a second extension ribbon in case the first was faulty.
Tried both cards in both slots with and without the ribbon (the ribbon is for sure the issue).
Contacted eVGA [COLOR=blue ! important][COLOR=blue ! important]tech [COLOR=blue ! important]support[/COLOR][/COLOR][/COLOR]
said they have no experience with these ribbons, but suggested their Power Boost to provide additional power to the PCI-e bus. Yes, I bit and I bought. No good.
I really enjoy the performance I'm getting with my cards and I love the fact that no matter what load test I run, I can't heat them past 71 degrees. I don't want to give up on this project when it seems that I'm ALMOST there (and I can make it look nice too
) Any advice would be greatly appreciated.
