Title: Driver and SDK for HD7970 Post by: Metta28 on April 11, 2013, 05:25:32 AM I currently have 3 7970's on one rig and 2 on another however once my local shop gets the 1x-16x risers in stock again it will be 5 on one rig.
I was reading a post saying certain drivers aren't any good for 4+ cards however post was pretty outdated. So any up to date suggestions on driver SDK combo for 5 x 7970? Thanks Edit: I am running Windows XP SP3 Title: Re: Driver and SDK for HD7970 Post by: DrG on April 11, 2013, 05:32:52 AM Don't know about the driver issue but make sure that you're using powered extenders for those 7970s. You can get away running 6 low end 7770s off 1 mobo without additional power, but 5 7970s will burn out the ATX connector on the mobo. You will need at least 2 or 3 powered extenders.

If not link me to what you do mean. Title: Re: Driver and SDK for HD7970 Post by: DrG on April 11, 2013, 05:45:32 AM Sorry the Newegg link came up dead.
I remember a post in the last week talking how to make your own powered extenders, search for it. Or go here: https://bitcointalk.org/index.php?topic=7216.0 and scroll through - that's like the how to on building a rig.

https://bitcointalk.org/index.php?topic=76121.0 Basically you want to send more power to the card and not have the card try to pull it from the motherboard - hence the molex cable sticking out on the side. Some places like cablesaurus sell them premade. |
