is there a reason for my miners not being able to connect?

Working fine here.  934 TH/s implies it's working well for others too...

Yeah, it was wierd. the one miner i have aimed at this pool all the time was fine. My other miner had issues with slush, and the wrong log in for btcguild. i fixed it and it ran fine. i then tried slush, and when Slush didn't work, the fallback didn't work either. wierd.

Will be listing them tomorrow.  I'm waiting on one response from friedcat RE: which rail this pulls off of the PSU from.  If it's pulling off 5v, I'm a bit concerned about how few PSUs can actually power all 49 ports at once since very few ATX PSUs will give more than 15 or 20A to the 5v rail.

eleuthria- I may have missed this, but what did you find out from FC about the power? confirmed that it uses 5V rail?

I have two 350W ATX P/S's and they both supply 30 Amps on the 5 Volts.  49 BE's draw 24.5 Amps.

[miner49er]

I have been rummaging in my junk and found a brand new Hiper 580W - 36A on 5v rail(I forgot this one did not have correct CPU Aux power connector for mainboard I bought long time ago), plus a well used Ultra 400W with 32A

does the wattage matter at all?

I've not received confirmation yet.  At this time, it is safe to *assume* it uses all 5v rail and get a power supply that supports 25A+ at 5v (26+ would be nice to have more than a 0.5A buffer).  If it also uses 12v, then at least you were safe (pretty much any PSU supplies enough watts over 12v to power 49 erupters).

Minor Pool Update
The difficulty has recently changed.  As a result, the luck charts have stopped updating as new shifts end.  This will be corrected shortly.


Update:  Luck graphs are now updated to reflect the interim shifts which are partially at old diff and partially at new diff.  The 'N' value has also been increased by 30% in order to bring shifts back to the 40-50 minute range.  This has no affect on your earnings, it only changes how much variance you'll experience per-shift.

+46 % difficulty increase- oh my aching BE's
My GPU's are all sweaty and crying  "Please don't unplug us yet! 2 more weeks? Please?"

Sorry boys, Yer retiring for sure.

Yes Wattage does matter it is all connected...  Wattage is calculated as voltage times amperage  or I * V = W (I is amps or current) ... so 5 volts at 2.5 watts is 2.5/5 or 0.5 amps. 

Each Erupter can be measured at 0.5 amps or 2.5 watts...  so 49 Erupters would be 49 * 0.5 = 24.5 amps or 24.5 * 5 Volts = 122.5 Watts...  or you can take 49 * 2.5 watts and also get same 122.5 Watts    So either of your two power supplys would work.. Just don't count on something that says it will do 25 amps to handle them.  Most electronics are at least in the 5% range of going either way.  I would want at least 30 amps or 200 watts to be safe.  Plust 5% of 24.5 amps is something like 1.225 amps.. so that is 25.625 and if your power supply happens to be on the negative side of that equation it is down that 1.225 amps and will burn up.

Isn't electronics and math fun?!?!?!?!?

TY for the explanation.

[eleuthria]

Update from friedcat:  The power supply must supply the current from the 5v rail.  This means your PSU must provide at *least* 0.5A @ 5v per erupter you plan to run.  Planning at 0.55A per erupter is recommended just to be safe.

So, my 5 Volt 30 Amp PSU's should be fine.

I wonder how long these old P/S's can sustain 27 Amps though?

Thanks,

You might want to start by just running 40 per...  

I'll need a couple of these once they're available separately - I already have plenty of BE's - don't need 40 more with each hub.

Its a plot to make us buy more erupters!

Just want to drop in and say thanks for the quick delivery! After messing around with hubs for 2 hours only to realize the power strip was off, I finally got another 14 BE's online!

I think your right.  Is there no limit to the depths Eleuthria and Friedcat sink to to get us to buy more of those things?

I'll take two hubs worth please.  Yes, I'm weak.

Has any one considered the mess these will make of your CGminer display? I've got 56 on one computer and even at 8 point(linux terminal) and the window the full length of the screen i can't display them all. I just use compact display and watch for green lights every now and then. as long as the display scrolls every now and then i'm content. I can't imagine running 100 on one computer. Also, with every increase in difficulty the blink rate decreases No more xmas lites. :

Don't get me wrong, this is tongue in cheek. I'm not against these. But at this point they require a special type of Miner to own them.

lol I just wanted to make sure I had my hub for the Gen3 chips

My understanding is these hubs will be a standard part of ASICMINER USBs giong forward, so when Gen3 comes around you'll easily be able to get a hub along with your order.  But yes, it's obviously a plot to make you buy more BEs.  It's also a plot to make *me* buy more BEs.  I can't order hubs separately last I heard from friedcat, only 1 hub per 50 BEs .

You can scroll up/down on the list with the arrow keys.  Learned that one back when I (foolishly) thought I could test each unit before shipping to avoid DoAs.
