MSI Z77A-G45: 7 PCI-E slots for only $115. Question is, will they all work?

[pontiacg5]

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!

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!

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?

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.

[RickJamesBTC]

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

You need an IvyBridge CPU... Celeron G1610 or G1620 eg.

[RickJamesBTC]

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.

The Pentium G2020 is also an Ivy Bridge CPU : http://ark.intel.com/compare/71072,71070

My bad, I have a celeron right before ivy bridge came out and thought that was it...

[Symon]

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

[Symon]

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

[RickJamesBTC]

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

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.

[RickJamesBTC]

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.

[pontiacg5]

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.
