where are u seeing this diff of 9? at your My Account page? or u are staring at the output from cgminer/bfgminer etc?
if it isnt on your account page, then u need to minimize that window and stop nit picking, u r gunna die of old age

USB miners always work at Diff 1, so I don't know why you're trying to change them...

I think diff 8 is quite good for your hashrate, isn't it?
Yes, the variance in your rewards per block is a bit higher, but Slush had to do something to preserve the pool performance and bandwidth in the current situation of increasing hashing power. I'm afraid not all ASIC users had manually set their diff accordingly...

What has your manually preset difficulty been like?

Why is Friedcat not responding to this  . Coupon for usb miners was fast.

What has your change been like? I mean, if it has made remarkable change in payouts. Previous diff, current diff?

Why don't you just buy hubs that work?

They cost more money but in the time you're waiting for new hubs and re-soldering them you could be mining.

I see that worker difficulty now adjusts automatically, regardless of the difficulty set through the web interface. Has this been discussed already?

Am I the only one that is not able to connect to the pool right now? On minepeon, it says that its is currently unavailable/dead.

 

 may be workable at 6 sticks a fan   with 10 hubs you would be okay with 60 sticks.  long term 24/7 365.

  if you get that psu to run  75 sticks and a few fans longtime I would be impressed with the quality of it.   60 sticks = 150 watts 4 fans = 10 watts that is 160 watts out of a 200 watt psu.  that is about the limit for long term use.  

 still 20 hubs = 170

2 psu's = 70

20 wires = 20

you would be at 250 usd  for 120 sticks and 0 overload issues.

  I forgot the fans  so 300 usd for 120 sticks and no overloading.  possible that you could do 7 sticks and a fan which would be 140 sticks and no overloading.

  let us know how it holds up with more sticks per hub and per psu.

How do you setup a PSU to power a hub instead of the AC adapter?

that's like 27 usb hubs required. dam. another £30 to £45 per hub or are you selling them

240 delivered today.. got some of the new blue and yellow ones.. the blue looks really nice

Thanks for the quick delivery!!

I send payment for 5 units allowed by my coupon 0.1 coupon (.5 btc) and send a shipping label as instructed in the OP.
I get a PM saying I need to send 0.15 btc per coupon and that the cost is 0.15.
Why is the cost of a 0.10 coupon 0.15 when shipping has already been paid?
This is a total scam!

I have still zeros by all my workers. :-(
When there is a non-zero number, will it become clickable and linking to the list of found blocks?

252730 is reported as valid on Blockchain and attributed to Slush.  Hopefully Slush will fix this one.  The 252722 is defo a weird late one, and not found on Blockchain.

A work in progress:



These are the 7-port hubs from MCM.  As you may have already noticed, these are just the generic hubs from China that's all over the Bay and sold dirt cheap albeit with less capable AC adapters. All MCM did was couple the hubs with better power units and marketed them.  I could have done better and further reduced the per port cost if I had put them together myself but I was in a jam as I was expecting more miners to arrive in a couple of days and I only have so much USB ports on my rigs.  I had to pony up for a 2-day shipping and for the applicable sales tax though which added a little to the per port cost but it's OK because I already ROI'd those extra expenses.  

MCM's site specified that the AC adapters are 5V 2.5A.  I then called tech support to verify the specs.  The gentleman literally called their warehouse while putting me on hold and came back on with the good news that it is in fact, a 5V 3.5A.  Here's a confirmation:



It supports seven miners with no issues; tested it for a few hours.  With all seven BEs hashing, the power units get very warm (an optimistically good indication that the internal heatsinks are doing their job of dissipating heat through the case) but one could still touch them for the longest time and not experience any burning discomfort.

The seven BEs registered 21W AC off the wall on a Kill-A-Watt while mining (100% load or thereabouts).  That's 3W AC for each miner.  Based on the BE's specified rating of 2.5W DC, that puts the AC adapters' efficiency at around 83% at 100% load; at 50% load (peak) it would probably be at least 85% efficient.  That's impressive for a wall wart.  If I'm not mistaken, this falls within the 80 Plus Bronze category.

I'm expecting a few more miners coming in on Monday and I intend to max them out and populate the two rear ports on each of them.  Here they are in action:
