Used Eligius for a while, loved it. Then they migrated the server and I started having problems with my miners getting work reliably. Hash rate fell. Slow response by pool operators, intially they denied any problems. Now pool is being migrated to different server again.

Switched to Bitminter during this. They are either having a really long run of bad luck, or something is wrong. Expected rewards have been consistently below average expected rewards the past few days in a row:

Now I'm not sure where to go! BTCGuild is dangerously near 51% (not that my hashrate matters, I'm just a drop in the bucket). Deepbit has high fees. Argh!

Do you still need some debugging on Titan? I have one, and am more than happy to help! Just PM me or reply to this thread.

Checked google docs spreadsheet. No Titan configs. I will try -I and see thanks!

Trying to read through all 37 pages of this thread... but I have a GTX Titan and using this to mine litecoins. Getting about 190 kh/s at stock clocks/voltages and no tweaking of launch config (just relying on auto-tune).

Does 190 kh/s sound right? Any flags to optimize a TITAN?

I posted on a separate thread, but I think it fits in with your OP. So I use BFGMiner on stratum for BitMinter mining, and have two workers:

Worker A = 260 MH/s
Gets about 68% discarded work
A:3192, R:0, S:6
ST:2, DW:7059, GW:1867, LW:17310

Worker B = 1800 MH/s
Gets about 24% discarded work
A:11414, R:8, S:0
ST:2, DW:3677, GW:924, LW:22936

Any idea why my slower worker (A) seems less efficient and seems to have more discarded work? How I can reduce this to mine more effectively?

Other thing puzzling me is why the higher hash-rate worker has fewer discards ...

On a separate topic ... any advantages of using BitMinter's Javascript client miner, versus BFGMiner on stratum?

If you scroll down that page further, a second chart shows cumulative payout. Seems like there is a huge variance in terms of expected avg payout and actual (4940 vs 4463 at the time of this post). That's nearly 10% below average!

Also note that the payout is hardly ever above average, and the rare times it is, does not appear to be 10% above.

Can anyone add support for BitMinter's API?

Where is a reputable place to exchange Namecoin for BTC or fiat?

I really like Eligius, but concerned that we have received no further word from Luke-Jr or WizKid. Their last post was 24+ hrs ago, and they didn't really have any useful info Do they care?

I notice in some pools you can select the difficulty for a miner:

So if you have a high hashrate worker, you can increase difficulty to reduce network traffic. How does this benefit you (the miner)? If you have higher difficulty, doesn't it take longer to return a share? Which in turn would lead to less rewards?

Read this thread. Many think bird in hand is better. The full Wired article can be read here:
http://www.wired.com/wiredenterprise/2013/04/butterfly/

But I quote from it: "They’re mad, because other companies — most notably Avalon Asics — have shipped hundreds of their own custom-chip machines. That’s already made the Bitcoin mining game harder than it used to be. One miner said that he was generating more than 15 Bitcoins per day with a 67-Gigahash-per-second Avalon rig he set up in late January. As of this week, his daily production had dropped to 4 Bitcoins"

So at 67 GH/s (!!) he lost 75% of BTC production over 3 months.

Not sure how to get a log out of BFGMiner, but after running on Eligius 3334 overnight (at 260 MH/s) I get these stats:

A:1177
R:145
S:307

DW:718041
GW:532
LW:721826
GF:29
NB:50

Seems to me that Discarded Work is extremely high?!

Why is my payout so low?

I'm doing about 2 GH/s, and with other pools I have earned about 0.1 to 0.12 BTC/day. But I mined for a whole day on BitMinter and only earned 0.036 BTC.

Any ideas why so little earned?

Been using BFGMiner 3.0.0 and 3.0.2 and both give me the same error others are reporting. Hashrate down, shares not increasing, lots of problems getting work from server. Nothing has changed on my end.

Rebooted miner, rebooted router. No difference. Can mine on other pools without any problems.

Had been mining with exact same setup last week. If client didn't change, and pool didn't change... maybe something in-between did. Eligius is across the pond from me, after all. Glad to know it's not just me though

Oil cooling, only way to go for this setup:

I'm relatively new to mining. First started at deepbit, then Eligius. Was happy with Eligius for a while, but lately have been having connecting (getting work reliably from their server). Not sure why, maybe because I'm across the Atlantic?

Was forced to switch to another pool because of my connection problems. Settled on Bitminter. Only mined there for a day, but it seems their system is set up for delayed gratification. I read the whole "shifts" thing but I got more confused by it. In any case, mined there at 2 GH/s for about 20 hours, any only made 0.009 BTC and 0.028 NMC.

This was much less than I expected ... again, maybe there is more I'm "owed" but need to wait for shifts to complete. Not sure, but psychologically it sucks! LOL. Oh well, gonna try Eligius again and see if my connection is more reliable now.
