Title: My First Open Air Rig - 4x 6970 1x 6950 - 2gh/s - "The Mine Cart" Post by: CrazyGuy on September 09, 2011, 06:51:31 AM "The Mine Cart"
I would like to share my first open air rig with you guys. Built inside of a storage crate, all cards are running cool at 2 gh/s total. 6970s clocked at 920/795 and 6950 at 820/700. All 100% fan speed with a little help from a rear box fan. Specs:

I want to see how you are holding those cards up. By the process of "jamming em in" I think ;D It is rather a "novel" design though.... very fitting with the homer avatar Title: Re: My First Open Air Rig - 4x 6970 1x 6950 - 2gh/s - "The Mine Cart" Post by: CrazyGuy on September 11, 2011, 04:27:20 PM Haha, I'll upload some more pics tonight. Couple of rods going across the crate holding the cards up.

How do you keep that thing cool within limits? I think the box fan is helping a bit. All cards are memory underclocked as low as they go without a bios flash. New Specs: 1x 6950 3x 6970 1x 5970 https://i.imgur.com/El61wl.png I should be able to pull a bit more out of the 5970 but I'm going to let it burn in at stock core clock for a couple days. Here's the video I promised to post. http://youtu.be/fqqcdfEYN6Q (http://youtu.be/fqqcdfEYN6Q) Title: Re: My First Open Air Rig - 4x 6970 1x 6950 - 2gh/s - "The Mine Cart" Post by: worldinacoin on September 17, 2011, 12:35:16 PM Kinda low yes, but there is some real mechanical engineering ingenuity :)

You rates are quite low. You should be able to pull ~336 MH/s at stock cloks and ~ 371 MH/s @800/300 for each core on the 5970. Yeh, both cores are under 60 degrees so I figured I could push it a bit more. Problem is, I'm hovering right under max draw on my PSU. I have the minecart switched off at the moment and I'm selling a few of the cards in the marketplace threads. |
