in case anyone is interested, I fixed the problem by using a stratum proxy

220 GH/s locally and on pool side

Would you please tell me how did you fix it? I have the same problem. Anybody knows how to fix with proxy?

How did you fix it by proxy? can you explain more?

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).

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.

Are these numbers what gives an idea of the number of errors?

(17 hours 35 mn)
LocalWork: 2,870,281
DiffA: 2,050,944
DiffR: 29,824
DiffS: 729,728

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.

Thats alot of stale shares!

I have 4 ants mining now, 14 hours 9000-14000 shares each and not even 1 stale.

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.

here's the cgminer status page after 45 mn

where do I see the number of errors? and %?

still averaging ~ 140 GH on the btcguild stats..

well that didn't fix it Sad

averaging 140-150 GH on the pool's stats, and 195-205 on the cgminer status page.

could it be related to not enough internet bandwidth? my connection isn't great and I actually have no clue how much bandwidth a total of 330GH miners would need.

oh I misunderstood
the other miner is just a block erupter cube that I still have

what difficulty should I have the worker? 128 or 256?

I set it to 256 for now..

On your first shot of btc guild there are 2 workers. What machine is the 2nd worker from? They are not both on the avalon are they?

When I said new worker I meant on btc guild.

Try creating a new worker on btc guild and then enter only that worker on pool 1. Leave pool 2 and 3 blank
