You missed the only version of drivers I've found that work reliably - 12.8.  You need to get rid of all the other shit versions totally and put 12.8 on.  It'll work then.

Also make sure you have .NET 4.0 Framework installed.

840 Pro is a good drive - I've got a few Samsung SSDs, they've been rock solid (PM830, 830, 840, 840 Pro).

All good with me, too.  Looks like Thursday evening to the sorting office.

Nah mate, it's running off an Intel NUC, so I need a 19V laptop PSU with a funny connector.  I have one ordered, should be here tomorrow or Thursday.

Thanks for the offer, though. 

I just ripped the PSU out of the carcass of my last GPU miner (GPUs sold on eBay yesterday).  The PSU will be running the Blades, the USB hubs for the Erupters, and the little Celeron 847 machine that runs the whole lot.  With 800W to spare, probably.  

I'm hoping he's too busy packing little boxes to be on here.

Huh, odd that I've never had bfgminer crash, ever, in about a year of mining.     That's on home-built machines (Asus boards), or on OEM Asus PC. 

Maybe your machines aren't as stable as you think?

USB miners always work at Diff 1, so I don't know why you're trying to change them...

If you need that loop batch file, then you've got something wrong with your machine.  You should only need to run bfg once.

2nd Blade ordered via PM.

847Pool is going to be down for another week or so, I'm going to swap hardware after a bit of a PSU flame-out.    New parts ordered, should be with me later on in the week.

SSDs are fine if you buy Enterprise drives, which are massively over-provisioned.

RAID1 is perfectly fine too - if you've got good backups, it's very difficult to beat as far as performance goes.  The servers here at work run a pair of 300GB 2.5" 15k SAS drives in RAID1, and they run very well, but they're only general purpose servers - no big database stuff.  Data is on a 8 spindle RAID6.

If you have to ask, you shouldn't do it.

Hmm..I can see those Red Furys replacing my Block Erupters.   

You could try:

- running the latest version of BFG - that's 3.2.0
- using the better -S erupter:all rather than all that crap icarus stuff which is depreciated.

Programs randomly quitting usually points to faulty RAM in the PC.

I have a few really cheap OCZ PSU (OCZ-CXS500W) which although probably not the best PSUs, they've been severely reliable for me.  I have two here, and both ran GPU mining rigs at very high loads for over a year - they were both pulling nearly 500W at the mains.  They've been solid, and they're very quiet, I barely hear them even sitting beside me on the desk.

They're now about to come back to life running some ASICMiner Blades.  Not bad for £30 PSUs from some Chinese OEM with OCZ labels stuck on them.

I thought shelved shares didn't really exist?  I also thought shelved shares were only paid out if you were still mining?  I've only seen shelved shares being paid while I was actively mining on Eligius, and when luck was high (IE not now, luck seems terrible at the moment).

Good review, but looks like a terrible PSU.  It would need to be very cheap for me to consider one.

Is there any reason why I can't run eu-stratum and stratum in Load Balanced mode in BFGMiner?  I'm thinking it might help if the eu-stratum server is a bit wobbly?  All the work ends up in the same place, right?  

I'm putting about 4GH/s in at the moment, shortly to increase to about 30GH/s.

p2pool really needs a fast clockspeed.  More cores won't make any difference. 

Only time I got decent performance from it was running it on an i3-3220.  3.3GHz, running bitcoin-qt with high priority on Windows.  It floated around 0.2s latency then.  On a Celeron 847 (dual 1.1GHz) it ran around 0.6-1.0s, and a Sempron X2 190 it was about 0.5s on average.
