Yea, but now pools performance keeps rising.

What do you have the minimum difficulty set for the U3 worker in Slush pool. If set for 256 it might be a bit much for that unit. I would suggest logging in and setting minimum difficulty level to 32 for a U3.

Anyone else having issues with Slush's Pool right now?

I'm trying to figure out a weird issue...

Originally I had issues getting my U3 to work on my desktop, so I got it up and going on my laptop... works great... problem is when I have to use my laptop for work, I have to VPN into my work, so I can't get pools to work anymore... so I had to move it back to my desktop...

I get CGMiner to work on my desktop where it recognizes the U3 now, after wiping out all device manager hidden devices and what not with it unplugged... problem is now it can see the device but it keeps saying:

Pool 0 difficulty changed to 32
And it never starts up... my URL, User, and Password is the exact same as on my laptop, but doesn't seem to work.

I can connect to GHash.IO's pool just fine though...

I might not be much help with connection issues but curious where you bought your U3 and how much did you pay for it?

Are you antivirus programs the same on both computers? Maybe it is blocking the port needed to connect to the stratum server. Also do you have to enter a USB ID into cgminer? If so, that would change between computers. Sounds like the program is seeing the stratum server but not your U3. If you are on a USB hub, try a USB port directly on computer and not a hub. Good luck getting it working. I have an Antminer S3 but every intriqued by these devices and would not mind owning one.

What's confusing is I can connect to GHash.IO's pool just fine but not Slush's Pool right now... so hardware is working fine... it's something going on with just that one pool...

I paid $120 including shipping for it... once I get my S3's this week and my S4 soon after, was debating on selling the U3 as I like the standalone miner idea better then having to keep my PC on for this USB miner.

It also makes it more difficult to spot if one of your miners goes down, if each has a unique worker ID then faults are easier to spot from the Slush stats page and its much easier isolate/fix a problem. All the miners will also get work of the appropriate difficulty too.

Hi all,

Okay, newbie question. Is it possible to direct multiple miners to the same worker? If it is possible are there any downsides?

Thanks in advance.

Mick

It's certainly possible... either directly or by running a stratum proxy locally (to reduce internet connection bandwidth usage).

The downside is that all miners will get the same difficulty work... not an issue if they're the same sort of HashPower but may be an issue if one is 2GHs and the other (for example) 32GHs.

So basically it steals your shares and pays you a fraction of what you would normally get because you had to shut down? Who gets the reward from those shares? Kind of messed up but good to know.

Nobody is "stealing" anything. If you are solo mining and find a block after 40 shares or 40 billion shares you still only get the 25 BTC. (Just an example)

Whats the formula? I assumed it was Your shares / Total shares x Block value = Your BTC reward

It is somewhere on the website but you are penalized every time you disconnect as the algorithm presupposes you are pool-hopping.

Not true. Over long periods it has no effect on your earnings. The times you disconnect just at the end of a round and are penalized are offset by the times when you disconnect near the start of the round, but are paid out the same as if you'd mined the entire block.

Thanks for the help indeed. So right now in cgminer I see it set as diff 60, and it is still getting the same average, when it should be at least 100Gh/s. My last question regarding this is how do I set the difficulty exactly? Out of all of my miners, I never had to look into changing that.

You set the minimum difficulty in the My Account page on Slush's web site. Minimum difficulty for each worker will show --- if it hasn't been set specifically; click on Edit for the worker you wish to change, type in the new setting and save. Give it a few hours for things to settle down. You are aiming for Slush to report near enough the same hash rate that CGminer reports, but remember that you are likely to see a lower hash rate anyway at peak internet usage times or if the connection routing is iffy. Try small steps rather than going for broke: in your example I would start with perhaps 75 and see what happens. I found it also works in BTC Guild.

Q: I have about £450 GBP to spend on miners ..... was going to get 2x S3, looks like I can get a couple for under £400 ...... would that be my best option? I'm fortunate in that I can run them for 12 hours a day on free electric (work), so power consumption cost are not an issue .....

Thanks

For that much you could buy a Jackson (Spondoolies SP-20) that has more than double the has rate of 2 x S3's.

Thanks for that, although looking at prices, SP-20 is around the £1300 GBP mark, I can buy an S3 with psu for £220 GBP, but I will look into the sp-20 some more ..... thanks again :

I think it redistributes them to everyone else who stayed online during the entire round.

Look at this post. Shares at the beginning of a round have less value then shares in the end of a round.
