1. I'm trying to get an MSI Z87-G45 mb running Win8.1 to mine with 7 cards but it only mines with 5.  Windows Device Manager recognizes all 7 cards.  Any ideas on how I can get cards 6 and 7 to mine  Huh
Use Linux, Windows doesn't support 7 GPUs.
Funny then, why are there several motherboards made expressly to run 7 graphics cards???
Maybe because not everyone uses Windows?  Huh

I believe the bug is in cgMiner 3.7.2

Could just as easily be a problem with the AMD drivers.  They aren't known for their stellar performance and proper behavior in all circumstances.

Regardless scrypt mining is no longer supported in cgminer.

This guy claims that the 11.12 or 12.1 driver can support up to 8 cards on Win7 or Win8.  I haven't tried it, so I have no idea if this is accurate or not:

Can anyone confirm that it is the WU that pays, and that I should choose the pool which give me the highest WU? I have noted some realtivly big difference from pool to pool.

The WU is what pays, but pools running stratum protocol have precisely ZERO effect on your WU. When your hardware remains the same, any change you see in WU is local luck and nothing to do with the pool.

Well, since only about 1/3 of the world has internet access, I'd be surprised if a vast majority of the world actually uses windows - since I'm pretty sure that it would be incorrect to even say that a vast majority of the world even has a computer.

I knew some grammer-nazi would whine about my saying people instead of PC-users  Roll Eyes

I contacted MSI tech support and apparently it's the MB to blame. They sell the Z87-G45 saying it can run multiple video cards. It has three 16x PCIe slots and four 1x PCIe slots. One of the "PCIe" slots is really a 32-bit PCI in the guise of a 1x connector. I'm returning it for a refund as being SNAD.

Has anybody tried the new ASRock BitCoin MB  Huh

The best way to get those to run 7 cards is

 Press Down, R, Up, L, Y, B on controller two at the scrypt selection screen

Sorry if this has been discussed earlier in this topic, but it's almost 700 pages long and I couldn't find anything while searching.

My question is regarding the --no-submit-stale option. Forgive my ignorance, but why would you ever want to submit a stale?

It depends on the pool.  On some pools, for example p2pool, a stale share may still be a valid block and so if you don't submit stales, you risk missing out on BTC.  Historically, there have also been pools that paid for stale shares and so you always wanted to submit them.  I don't know that any current pools still do that though.

Ok, thanks. That clears it up a bit. I'm not sure how a stale share can be a valid block though. If I'm not mistaken, a stale share is the result of an "old job" from the pool. In other word, a job that was submitted after someone else had already solved the block.

Whatever you want - chase your tail.  Windows doesn't support 7 GPUs, period.  Whatever you think doesn't change that fact.

Motherboards may have 7 PCI-E slots, doesn't mean they're made to run 7 GPUs.  Other things use PCI-E - RAID cards, sound cards, NICs...

So, yeah, use Linux.

P2Pool has it's own share chain - on p2pool you solve high difficulty shares, not blocks.
Thus a share can be stale due to another share being accepted ... even if the network BTC block hasn't changed.

What this means is that any block found when mining on P2Pool will actually still be a valid BTC block until the next BTC block is found on the network - even if it is a stale share.
P2Pool will send the stale block to the bitcoind in the hope it is actually a valid network block - which it will be ~95% of the time.

This change to p2pool (quite a while ago) meant that you were no longer earning less mining on p2pool - however it does require EVERYONE mining on p2pool to submit stale blocks - which is done by submitting stale shares in cgminer.

Hi!

Great job with CGminer and BFS!

I was wondering if you're still giving support for cgminer 3.7 which supports GPU and scrypt mining.

My miner is running and showing the speed in kh/s (scrypt) but till date it has not been able to solve any block. Running CPU miner (which runs at a fraction of the pace) has solved many blocks in the mean time with the same coin.

I'm solo mining many alts.

I'm getting a lot of hardware errors also --

My miner is running and showing the speed in kh/s (scrypt) but till date it has not been able to solve any block. Running CPU miner (which runs at a fraction of the pace) has solved many blocks in the mean time with the same coin.

I'm solo mining many alts.

I'm getting a lot of hardware errors also --
Thanks!!

Check your intensity.  It's probably too high.  Could be faulty GPU as well.

P2Pool has it's own share chain - on p2pool you solve high difficulty shares, not blocks.
Thus a share can be stale due to another share being accepted ... even if the network BTC block hasn't changed.

What this means is that any block found when mining on P2Pool will actually still be a valid BTC block until the next BTC block is found on the network - even if it is a stale share.
P2Pool will send the stale block to the bitcoind in the hope it is actually a valid network block - which it will be ~95% of the time.

This change to p2pool (quite a while ago) meant that you were no longer earning less mining on p2pool - however it does require EVERYONE mining on p2pool to submit stale blocks - which is done by submitting stale shares in cgminer.
Thanks again. I think I got it now. Based on your description, I will continue to submit stales when I'm mining on p2pool, but enable the --no-submit-stale option for other pools.

Hi!

Great job with CGminer and BFS!

I was wondering if you're still giving support for cgminer 3.7 which supports GPU and scrypt mining.

My miner is running and showing the speed in kh/s (scrypt) but till date it has not been able to solve any block. Running CPU miner (which runs at a fraction of the pace) has solved many blocks in the mean time with the same coin.

I'm solo mining many alts.

I'm getting a lot of hardware errors also --
Thanks!!

Check your intensity.  It's probably too high.  Could be faulty GPU as well.

Reducing the intensity will still generate hardware errors . There appears to be some hardware error generated per KH, i.e. halving the KH/s will reduce the no. of errors per second to half.

I still don't get any share with lower intensity.
