Topic: RISERS for 2 coins - page 3. (Read 4455 times)
Thats not true. Ive run 30 5850 with 5 cards per board as well as 2 rigs with 4 5970 each. Ive used more than 50 of these. Never had any problems. They work great.
That looks like improper grounding or way too many GPUs were being run through the board. You need to make sure as a rule of thumb you're not running more than 4 cards per motherboard without Molex extenders.
EDIT: Also, any and all dual GPU cards need run through a Molex powered cable if using an extender. This includes 5970's, 6990's etc.
Here's the Molex powered extender one needs to avoid such over-draw: http://cablesaurus.com/index.php?route=product/product&product_id=12

Wow. Ive been using these since I started mining. Ive never had any problems.
This happens to some people when not using powered extenders, depending on the # of cards being run:
What causes that to happen?
