sure, only solo will make 100% mining profit

pool reward will be 70% at the best, of solo mining

try cpuminer
six gridseed units working fine for me with ebt solo mining
here is my config:

This coop is the best chance to see if black arrow delivers.

And frankly they look shaky at best.

They refunded over 100,000 usd  on this r17 sale including  7 of 12 shares to me.

If we are not hashing in under 20 days this will be dead deal.  If this deal is dead you will be out your 12k.

There are quite a few holes in the boat.

maybe you overclock it or asic is unstable, so he sents wrong shares

try to use cpuminer instead of cgminer if you can, cpuminer more stable

also try to connect only to online pool and see if it accepts shares, so you can see how stable your asic(very low rejected(<5%) = high stability, mid&high rejected(>20%) = low stability)

updated:
do you check right(scrypt) algorithm?

i think you using a asic, so it's  asic/cgminer solo mining bug

you can try only 1 pool(local wallet), without second

Just the ship date is so far away

is shipping really $38  for 1 single unit

I ordered this morning and it took about 4-5 Hours before orderstatus went to Processing, so wait a bit more and see.

I am afraid there has been a fork.

Leetpools is working on block 7519, last block found was 7500. Blocks found since 7486 are all orphaned. I sent a manual payout since block 7494 and I have not seen the first confirmation on my wallet.
My wallet is still at block 7511. What block is everyones wallet at?

An official block explorer would really help.

Interested in buying some of these gridseeds while their cheap.... Any idea if someone will be around to answer payment questions?
