May I ask what the objection is to risers?
Imo (which is ONLY an opinion), you'll fry something with that setup.
The only objection to the risers is that my setup is already mounted on wood and ready to go and I've never used risers before. I'm not sure how I would mount something on risers. I've seen pics but they all look custom and havent found any metal forms that would work out of the box.
Woods good
But you really need to separate those cards apart by using risers. The basic rules are if the card is powered by a PCI-e then use a powered riser, if you can afford them then get the risers that connect using USB cables. If the card is on the list here
https://bitcointalk.org/index.php?topic=36061.0 then use risers that have the switching built in, there should be a small capacitor at the fat end. You may be unlucky and get a motherboard that is not on the list but in that case just short A1 B17 and you will be away but add it to the list please.
Thanks for the info man. I appreciate it.
My question is, will they not cool being so close together?
So you spent hundreds on GPUs not knowing how to set them up properly, just hoping it works?
It wont. You can probably run 2 cards without risers. Maybe if you had 280x's you could undervolt a ton and run 3-4 on a single mobo in a cold area with extra fans and have temps under 90c
No, I have 10 rigs right now running 2x GPUs but this is the only one that has 4x pci-e x16 slots. I've been running a 10 MH/s system for about a year but decided to try a 4x pci-e mobo since I got a great price for it. It takes all of 30 minutes to learn what you need to learn if you know where to look but I wanted to see if anyone here had any HELPFUL advice or experience instead of sarcasm or negative comments.
So since you obviously know more than me can you point me to a link for something that I dont have to custom build to mount the 2 cards on that I need risers for? (something that is not a milk crate).
