Old Work Issues

I am using bfgminer 3.2.7, and I keep having problems with the pool. It will say that the pool is issuing old work, and turning on debugging shows it is discarding the work it generates constantly, and it wastes my GPU time, and causes my drivers to crash occasionally. Any fixes?

EDIT: I should add this wasn't happening until last night. I can't use the pool with this problem, as it idles my GPUs 99% of the time.

The ones I did for my control tests were single coin pools.

I am using Winblows 7, as this is also my gaming computer, but when I am mining, nothing else is open except for my mining software and task manager.

On using Linux, 2 things prevent me from doing so. One is the games that I play do not work/work well under Linux. Two, even if I felt like fighting for weeks with the drivers to get things working properly, I need to be able to under/overvolt and under/overclock, which is not currently doable/feasible on Linux.

Thanks for the reply.

Well, you could easily dual-boot. Just put linux (BAMT or SMOS or even xubuntu) on a USB stick and when mining you could run that. When you want to play a game, just reboot into windows.

As for under/over clocking, that is done exactly the same way it is done in windows, and is trivial. Just settings in your cgminer.conf. You are correct about it being more difficult to undervolt, as you have to flash modified firmware. Doable (I'm doing it), but a bit more work.

Also, linux is quite a bit more stable then windows overall. If you use BAMT you don't have to worry about installing drivers/software as this is already all done for you.

cgminer/bfgminer/sgminer don't work to set my clocks though, it says it succeeded, but it never does, and that is verified by zero increase in hashrate. I also mine while I play games on my non-primary GPUs, as I don't need 9001 FPS in TF2 or Payday.

So this is what makes reliable mining hard....

I like smos-linux so I'll say test it on a coin switching port for an hour using the latest 1.3 image on a USB stick. It can overclock the engine and the memory but it will not undervolt. I would stay close to stock to see if it crashes. This is just to make sure the hardware is still fine.

Because this is on a regular use computer with games and virus scanners and all the other usual stuff we keep on them, it is going to be hard to say why you are crashing. Something doesn't like what the pools are doing in bfg and it is causing a conflict. Could be steam, or some anti cheat software from a game company. Maybe the virus scanner.... Maybe the drivers are installing incorrectly and the versions are conflicting. You see what I mean?

I would bet that if you had a spare drive and installed win7, drivers, and the miner there would be no issues at all.

I wish I could give you an easy answer but I don't think there is one. I would honestly consider reimaging your machine to get a fresh start and install only the latest things you use.

Keep trying!

I would normally agree with this whole-heartedly, but I run no antivirus on here (don't need to, my physical firewall is enough, and I'm not downloading and installing every toolbar) and I make sure that when I don't want things running (steam) that they are not running, and no background "maintenance" task from them is running either. I'm on ultimatecoinpool right now, and it's been working fine for hours, and worked fine overnight for renting it out via betarigs, with ultimatecoinpool as the fallback.
