Can anyone help point me in the right direction please.

I bought 4 BFL SGL600G units and hooked them up - I've made a huge mistake, paid a massive price and stand to lose a fortune but that's my problem. Let's just say temporary insanity gripped me. At the end of the day it's only money right (I have to keep telling myself that)

I'm having to use the bitminter client since it's the only way I can get them to play. I have been using erupters on eligius without any issues as you might expect.

When I run BFGminer with these and no command line switches other than those needed to access the pool, it sees all four of them just fine, but after a few minutes running the Eligius server sets the difficulty to higher and higher values, 2,4,8,16,32, etc.

What's happening is that some of the workers (it looks like each unit has 10) update with the new difficulty and some don't.

So that after a while there will be work being accepted from workers at 256 without a problem but others being rejected from those stuck on 2 or 4 or whatever (with an "unknown-work" error)

Sorry if this is a pathetic explanation, I haven't a clue what is happening, can anyone help?

So what sort of hashrate are you actually getting on Eligius?   I know my lowly Jalapeno does spit out some errors now and again, similar to what you're reporting, especially when starting out first.

When running before the errors start all 4 combined produce a fairly stable 235-240 GH. The problem is when after just a few minutes I start seeing the rejection errors (unknown - work)

I suppose in many ways I've bitten off more than I can chew because I just don't know enough about the software (BFGminer) or the SGL600G units to start troubleshooting in any coherent or methodical way.

At present running the bitminter client makes things childs play but even that has produced some issues over extended periods where the 210-230 GH rates per shift starts falling away to the 190-180s before I stop it and restart them manually (which for some reason seems to work.)

Occasionally the machines will stop and restart themselves, I don't know whether that's normal. Every time anything happens that isn't expected I start to get paranoid these things are going to pack in.

What's really pissing me off is how much I paid for these, a stupid amount, and yet I absolutely know they're never going to make me anything. I knew this before buying them but did anyway like I was possessed or something. I don't know what you'd call that, only words I can muster are utterly stupid.

Within about an hour of getting back and setting them up I sat in a cold sweat and thought "what the f*ck have I just done..."   Cheesy

The first thing I'd be trying is a different power supply.  I know the PSU BFL supplied with my miner was a piece of crap.

Yeah I don't want to divert the topic to hardware, if money was no object then I'd have them in bits and replace the fans and the psu's.

As it is I have a dilemma of not spending a penny more on them while trying to get everything I can from them - damage limitation mode well and truly engaged at present. I've so far managed to refrain from punching myself in the face.

I have one spare corsair HX650W unit but that only carries, according to their website, 20AMP on the 5V rail (although the brick label says 30A) and then 53A on the 12V rail. Just don't want to be adding to the wreckage.

What I was fishing for in the OP is whether there is any obvious command line switches I'm missing when using BFGminer with SGL600G.

I have them lashed to a 12m USB lead in a loft because the racket they make is unbearable in a small room. That may cause some issues but I'm not convinced it is that causing any specifically, they do work for long periods without any obvious problem although the bitminter client has a long list of "stale or alien proof of work" entries in the log. Also the occasional extraneous data received entry.

Since 10am this morning (UK) I've seen shift results of 223,220,222,228,218 which is quite stable compared to the numbers I saw the last few days.

The bitminter client is showing rejection rate of 5% currently - miscalcs running at an easy sub 1%

I hope it's an active USB extension...
