1  Alternate cryptocurrencies / Mining (Altcoins) / Cannot run 7 graphics cards on MSI 970a-g43 on: December 11, 2017, 02:31:29 AM
System components:

MSI 970a-g43

6x GTX 1060 3GB
1x GTX 1080ti

1x Seasonic Focus PLUS 850W (secondary)
1x EVGA G2 850W (secondary)
1x XFX 550W (primary, powers the motherboard+CPU+drives)
(All graphics cards are powered by the same PSU that powers their riser, if one is used.)

OS: Windows 7 x64

I am attempting to get the following configuration to work:

(Slots ordered by increasing distance from the CPU)
PCIe x1:
One powered riser to a 1060 (powered by the EVGA)

PCIe x16:
One powered riser to a 1060 (in every case that the system booted, this card in this slot was used for the display, as is expected) (powered by the XFX)

PCIe x1:
One powered riser to a 1060 (powered by the EVGA)

PCIe x16:
The following 4-to-1 splitter, with 3x 1060s and 1x 1080ti installed:
The 1080ti and 2x 1060s powered by the Seasonic, the last 1060 by the EVGA.

Each time I attempt to boot with all 7 cards connected, no graphics output is shown on the monitor.

Even more confusing, after reaching a stable configuration with 6 cards (6 can seemingly be reached with any combination of cards and risers), and attempting to boot with a 7th card connected, something gets munged. When I undo the addition of the seventh card, I find that I can no longer boot with 6 cards, a configuration that had just previously worked. Clearing CMOS at this point, does not help.

I find that I can only boot again with 6 cards after going back to 5 cards, clearing CMOS, booting to Windows with those 5 cards, shutting down, and then adding the 6th card before booting once more.

Previous stable configuration, before attempting to install the 1080ti (again, in order of increasing distance from the CPU):

PCIe x1:
One powered riser to a 1060 (EVGA)

PCIe x16:
One 1060 installed directly onto the motherboard (XFX)

PCIe x1:
BLOCKED by the card installed in the previous slot.

PCIe x16:
The aforementioned 4-to-1 splitter was used with 4x 1060s. (All of which worked flawlessly.)
3 powered by the Seasonic, 1 powered by the EVGA.

Additional notes:

I've tested each of the graphics cards, risers, and PSUs individually. The BIOS for this old board is the latest available (with no settings for 4G decoding or PCIe link speed).

I do not believe that the 4-to-1 splitter itself is the problem, as it still works with 4 cards connected to it.

I've been stumped on this for quite some time now, so I'm about ready to accept that 6 cards is as far as I can expect to push this motherboard. Any advice is greatly appreciated!
2  Alternate cryptocurrencies / Mining (Altcoins) / Asrock H81 Pro BTC sees only 4/5 cards. on: April 07, 2014, 02:51:31 AM
Hello, I seem to be having a problem getting all 5 of my cards recognized by any OS, even with the use of dummy plugs.
When I checked it out with BAMT (which shows, upon each boot, which cards it finds), I found that it only saw one of my 77xx series cards.

To continue checking, I removed the 7790 and it saw all 4 remaining cards.  Then I reconnected the 7790 & removed the 7770, however, it also saw all 4 remaining cards.  This leads me to believe that there's some limitation by the motherboard, CPU, OS, or some factor, other than the actual cards (or their connections).

My mining setup:

Asrock H81 Pro BTC
Intel Pentium G3220

3x 7850
1x 7790
1x 7770

Thermaltake 600W PSU & Thermaltake 700W PSU, load distributed as follows:

Thermaltake 600:
Motherboard & CPU
2x 7850

Thermaltake 700:

Operating systems tried:
Ubuntu 12.04
Ubuntu 13.04
BAMT 1.4

All risers are powered, and powered in a way such that the riser is always powered by the same PSU as the 6 pin PCIe connector to its corresponding card.

My thought is that the problem is the Pentium CPU's limitations on "PCI Express Configurations", seen on the Intel site, under Expansion options.  Does anyone have another idea why I can't get all 5 cards running?

I would appreciate any suggestions!

I'm looking for a bond with a relatively high output that's not a ponzi scheme.

I'm looking at BIF.1YR.LOAN right now.

Are there any LTC faucets?

Is there a way to use a Unix script to mine with minerd on Ubuntu 12.04?

I was able to backup my wallet, although I don't know how I can import it back into the bitcoin client when testing on another computer. Right now I'm using version 0.6.3-beta.

I'm going to be upgrading to 64 bit Windows 7, so I'd like to make a COMPLETE backup of my wallet and all addresses.

How many of you think Pirate is just going to run off with the BTC vs refunding the shareholders?

I'm wondering how I can set up an LTC miner to run either at certain times, or when the computer is idle and not in use.

I'm using minerd at the moment.

Hello everyone.

I'm wondering if I could get some advice on what assets I should purchase shares from at GLBSE. I'm looking for something that costs 1.05 BTC or less per share.

I'm thinking about NASTY, FUTUREFUND, and FPGAMINING, but I'm still looking for something with a higher % output.

I'm kind of hoping to find an equivalent for Pirate@40's FOO.PPPPT, although I understand that the dividends will most likely be smaller.

The eWallet pool seems to have gone down.  I can't seem to mine any LTC at the moment.  Can't view much of the site either.

Is anyone else having a problem with the site or with mining?
