Do ASIC miners make more profit using multipool?

Mine sure do  

[flound1129]

I tried to move my poor rig to multipool sha256, but it is not as expected.   5 USB erupters with only 1,65GHash/s after 15 minutes hashing BTC on multiport are reporting 8 accepted shares, 2 rejected and 8 hardware errors. Tried moving from eu to us server, tried changing user difficulty from 2 to 1 (cgminer 3.1.1 reports much higher difficulties), no change. Allmost all lines are "stratum from pool X requested work restart". Moving back until someone gives advice for setting small hash miners with sha256 multipool...

Yes, this is a concern. I have both BFL Singles and Block Eruptors running. My BEs run great for FRC, TRC & ZET if I set their Diff to 1 on my Account page. Since BTC is a P2pool it operates differently and species the difficulty. P2pool moves very fast and I'm not sure BEs can keep up.

I feel like I'm getting credit for shares submitted by my BEs, even though my BTC accepts are very low, but I'm not turning off my BFLs to test it.

Flound, can you shed some light on this BE issue in the BTC pool???

The high difficulty should really not matter that much.  You will submit fewer shares, but at higher difficulty so your overall shares should be the same.   P2pool changed from 10 second blocks to 30 second blocks a month or two ago to help increase the efficiency on ASICs.

I tried re-enabling custom difficulty last night on one of the p2pool nodes.  The result?:

 Local: 572GH/s in last 10.0 minutes Local dead on arrival: ~23.9% (21-27%) Expected time to share: 33.2 minutes
 Shares: 1 (0 orphan, 1 dead) Stale rate: ~100.0% (20-100%) Efficiency: ~0.0% (0-96%) Current payout: 1.5889 BTC

Granted, it looks like we were on TRC most of the night.  But efficiency dropped on both p2pool nodes (I'm assuming the high CPU use on this node affected the other one)  So custom diff is being turned back off for now.

I hope that the p2pool author will address the efficiency of p2pool soon, there is so much hashrate out there that he could attract if the client ran a little better.  Right now we are on it until we hit around 25-30 TH.  Then I will switch the pool back to using Stratum for BTC (I'd rather stay on p2pool, but as of now it's really not meant for this application.)

In the meantime, the altcoin profits are more than making up for any perceived loss of income with P2pool.  Currently I have a profit of ~0.05371482 BTC over the past 24 hours with my Little Single (~28 GH), which is over 250% what I would have made just mining Bitcoin.

I'm going to work on getting a Profit/MH/Sec and Profit/GH/Sec graph up on the main page so people can see exactly how the multiports are doing, but it requires a little backend work.

Nope, Block Erupters remain 'steady green lit'. And CGminer just blanks out and sits there until I 'Q'.

I have a MP worker called BE just for Block Eruptors with Diff set to 1 on my Account page.
DL cgMiner 3.8.3 for your ASICs (cannot be used for GPUs): http://ck.kolivas.org/apps/cgminer/

This is my bat file:

Has the site planning to add more sha265 coins?

[Illutian]

Weird, extracted 3.8.x, but failed to change the shortcut to 'cgminer.exe' (was cgminer-nogpu.exe). And it's working.

Either MP fixed the issue or 'cgminer-nogpu.exe' is using a fixed file now that works with MP.

Wonder what caused this. It was the first time I've ever seen this error.

[Aurum]

3.8.3 does not have a program called cgminer-nogpu.exe.

Your shortcut is probably pointing to the old directory. Delete it and make a new shortcut from the new directory.

That message happens when you get banned by stratum (for submitting too many shares above target, or for too many authorization failures).  It's supposed to last for 1 minute, but there were a few instances in which I had failed to set the variable BAN_TIME in the config, so it threw that error instead of unbanning you.

I thought I had found all the instances where BAN_TIME was not set but it appears that several of the PPC pools eluded me..  Those are fixed now.

What's your share difficulty set to?

[flound1129]

TAG is up for testing on 3351

TAG is up for testing on 3351

TAG mines fine as viewed from my cgMiner screen   

Please add a TAG line to the stats page so we can see what it looks like to the database.

That's been at 64 most of the time.

EDIT: Hashrates usually lie around 330 KH/s when everything is Ok

[Pentel]

The EU server is down for me, BFGminer as switched to US server.

EDIT: sha256 mining.

[spul1]

yeah, for me to, and the site is showing only half of my hashrate. Is it just a visual glitch or is just half getting accepted? (sha256 multipool).. it was fine on eu server.

[STT]

The TAG coin was showing over 100x profit of BTC mining so I set that up and it seems to be ok.   No real amount of rejects, cgminer hung once but that happens anyhow


On the multipool Ive not been able to connect to stratum always, so then I used getwork, now that kicks up a fuss so I was using the LTC port.  Might just be me, sometimes a reboot helps so feel free to ignore, I'll post up screenshots if it persists.
How many shares are we allowed to submit per minute without triggering the anti spam thing, Iam only a single 7950 but I have bad latency sometimes so I use the lowest diff

Anyone know of a working LUCKY wallet /exchange because that is consistently high profit, its 80x now

[ozoner]

TAG works fine for me too.

We will get these TAGs we're currently mining when the coin is officially added to the site, won't we?
