Something I noticed on one rig...
This one is the first one to give me fits. Occasionally, when mining, it will jump straight to the ubuntu login screen. Sometimes it did it right when mining started, sometimes after a while. One card would often completely stop, just turn off (6 r9 290's)
Anyway, to make a long story short, I eventually traced the problem out to the angle I was putting on the USB riser cable in the middle x16 slot, as well as the 6th 1x slot. When I'd troubleshoot the problem, I'd often unplug and replug the things, which would fix the issue for a while. Then, I guess after some time, the riser would move. Restarting it in this condition was always different, sometimes it wouldn't boot, sometimes fans would spin up on boot. Other times it would be perfectly fine, except one card would not mine or start mining. I figured that out, and reworked the cables and it's going strong since.

Why do you care if the thread gets bumped? It's about a motherboard, not about you. If you don't want to help or be a part of it, just ignore it. It's the only thread about these with any substance, and I'm trying to figure out why I cant get more than three cards to work in them.

I don't know why this thread keeps getting bumped.
FYI, I did not use ivy bridge CPU. I used Sandy Bridge, and 6 video cards worked in them. Up to 8 radeon 5870/5970 GPU cores with Windows 7 + driver 11.12, and up to 6 radeon 7970 cores with Windows 8 + driver 12.6 for 7970.
The requirement for ivy bridge is a myth. I don't know where it surfaced, but it's a lie and unbased. Just because Ivy Bridge has PCI-E 3.0 lanes and Sandy Bridge has PCI-E 2.1 lanes doesn't mean anything. The CPU and graphics cards will negotiate to the highest common spec.

These aren't working for me. I installed bamt 1.3, wouldn't take more than three cards. Installed xubuntu raring whatever, and the beta drivers, still no go. As soon as I plug in four cards, it won't boot up at all. Really doesn't seem to matter what I install, I can't get the mobo to do anything once that fourth card is plugged in. I'll do more testing later on, once I get these motherboards out of the racks. I have been snagging up the pro btc boards at retail cost from newegg every few days, finally have enough to get all the msi boards out. I'll probably leave the msi boards running a pair of 280x cards in pc cases, sit them in random corners around the building for heating

And 6 with the PCIE presence short ! I'm happy

Well i reinstalled BAMT 1.3 for the 3rd time and it worked directly (with 5 GPUs !)

You need an IvyBridge CPU... Celeron G1610 or G1620 eg.
The Pentium G2020 is also an Ivy Bridge CPU : http://ark.intel.com/compare/71072,71070My bad, I have a celeron right before ivy bridge came out and thought that was it...

I have the 1610s in a lot of computers. That's not the only thing needed to make this board work. I hope I can figure it out.
Oh I also use the 13.1 techpowerup catalyst... that's what did it.

Sorry, it was for RickJames 
I'm using Debian with just the minimum, ATI Drivers + cgminer 3.7.2. I have 2Gb of RAM and a Pentium G2020. I'm using 4x 7950 and 2x 280x.
It always works with 4 GPU and never with 5... i tried almost everything.

No news, no time to try a reinstall right now. Too busy shipping out risers

Some news ?
For me it's impossible to work with more than 4 GPU.
I have a Pentium G2020.
I have no idee why. I tried all the combinaison of the GPUs and... always OK with 4 but not with 5 or 6 !

Are you really asking for help, or are you just making a statement? If you are asking for help, you've got a strange way of doing it.
Are you using windows?

I'll check back in a few hours after trying it. It would be so useful if someone could put together a BAMT version that included current drivers. Then I wouldn't have to do installs every time!
January 21, 2014, 10:21:28 PM
Testing with USB risers is fun, I lay out an entire 6 rig machine in a cool looking pattern across my kitchen table. Never could do that with ribbons...
I also use g1610s, so our setups are identical except OS version!
Good luck!

Yep, celeron g1610.
I guess I can try a raring install with old drivers on one of them, see how it works. I've got an open box, moved all the cards to a setup that always works with 5.

Silly little noob, you really shouldn't be calling people out when you've no idea what you are talking about
Rick,
I've used many different drivers, I've got 2 6x 280x rigs, 1 6x7950 rig, and now 4 6x 290 rigs actually working. For the 290's I used the 13.11 beta drivers that were just released on January 8th, the 280x uses an earlier 13.11 beta but I'm not sure exactly. It may have even been the r9 launch beta driver, because that was back in November...
So long as you are aware one of the 1x slots will disable it doesn't really matter what you use. You just can't use three and four at the same time. If you are using USB risers your setup is identical to mine, no external jumpers at all...
Which version of linux? I use saucy salamander for the 290's, but the 280x's and 7950's are still on raring since it seems to work. Raring will blackscreen after installing the latest beta driver with 290's, the install log mentions something about a kernel failure. Saucy does not have the same problem apparently. I never could get 13.12 to work at all, not with raring or saucy, though I just tried with 290's. They would all detect just fine, but only one would mine at a time, kinda like they were needing dummy plugs. I don't use any at all with 13.11...

I'm using 12.10 still, haven't bothered to change because it has been so stable on so many of my other rigs. The 13.12 drivers work on all of them as well.
I've got a system for doing installs, doesn't take me any time and it works 100%. I'd hate to start upgrading software that otherwise works, looking for new bugs to stop my mining!
Strange, I never tried anything older than raring. I'm kind of bummed I'll have to update my process a bit, but I'd bet it would work for older stuff as well still. Seems stable to me, the 290's have been at ~880kh/s for a few days now.
Are you using an ivy bridge CPU?
