Powered Riser needed for rig pcie x1 to pcie x16

[Jimbit907]

Hi Guys,

So heres the story:  I have a normal(not so big) HP box with motherboard GA-H61M-S2P, with a HD5970 fitted into the pcie x16 slot which there is only one on the mobo.
Now i want to add a HD7970 but it seems like i cannot squeeze it in right at the bottom directly where the pcie x1 is because its way too cramped. So i was thinking of getting a powered riser, connect it from the pcie x1 slot to the card and leave the card more loosely out the box..

My questions:

1. Can i do that? (connect it loosley with a powered riser)
2. Will that work with a powered riser?
3. What exactly do i need to do?  (keeping in mind that there is already a 6pin and 8pin for the HD7970)

thanks in advance

Bump. Apparently, this guy still needs some help.

make sure your power supply is sufficiently rated to run 2 5970's. They have a total board power rating of 288 watts each and draw power almost exclusively from the 12v rail, so unless you have ~60 amps on the 12v rail of your power supply, don't bother, or you will have a failed power supply.

Other than that, using a riser can, and should, work. Use powered riser if you want, I never had a need for powered risers, just regular ones worked fine for me. If for some reason your graphics card does not detect, double check to see if everything is plugged in good. You may need to do a pci-e presense short too if it continues to not detect in rare cases (google it).

1) Yes you can, but you need something to support out of the box.

2) Yes

3) Just plug in and start mining. I don't really understand your question.

You will have a hard time getting the right driver for HD 5970 and HD 7970 due to the driver not compatible with both. I would try an older driver like 2.6 or 2.4.

I suggest you customizing your casing, or just simply no casing at put it on the floor

per last comment hopefully not a carpeted floor...basically if you have no way to secure it its bad if it gets bumped and bumps the wrong thing basically.  Thus why most the big gpu rigs you see are in these custom made housings not a normal case.  I still remember a guy in college years back who had 8 systems built onto a piece of plywood mounted to his dormroom wall.....was awesome!
