I'm pretty sure its because of the amount of stale and discarded shares, which are due to hardware errors. You also have a high amount of get fails at 10%. These figures are massively higher than I get.

I'm at a bit of a loss here to be honest, maybe someone else can chip in. The only thing I can see that looks like it could be causing it is that your temp is a little on the high side, these really need to be kept cool, where have you got the miner?

We keep ours in an unheated cargo loading area and they never get over around 42 degrees.

Each block is stacked on top of the previous one. Adding another block to the top makes all lower blocks more difficult to remove: there is more "weight" above each block. A transaction in a block 6 blocks deep (6 confirmations) will be very difficult to remove.

thanks for the input guys.
bought it directly from the manufacturer in China.
I'll contact them to have it replaced/fixed/whatever.

there is definitely something I tried all my other miners on the same pool and not a single one of them is more than 1-2% off the hashing speed spec.

my temperatures are a little higher than what some of you have been running but I don't see how this could explain it. heck, they even recommend a target temp of 50C.

DiffA: 2,050,944
DiffR: 29,824
DiffS: 729,728

odd - cgminer status now says the btcguild server is dead.
I thought it was another problem with this unit but I just added the btcdig info again and it's connecting/hashing fine with btcdig.
my other miner on btcguild is still working fine though. like I said - odd.

upping this one last time in case some had an idea?

no matter stock or o/c'ed to 1400 it's hashing with a ratio (DiffS / Local Work) of 12-15% no matter either pool (only tried BTCguild and BTCdig).
API log shows very consistent numbers throughout the 16 miners (all within 1% of each other).

Local hashing rate (Cgminer status page) is on spec (200 stock) - (215/220 @ 1400).

in case anyone is interested, I fixed the problem by using a stratum proxy Smiley
220 GH/s locally and on pool side
