Its running already, but im unsure about the d=128000 setting shown on the frontpage of zpool.ca
Does it do anything?
It should change the default difficulty to a level appropriate for the compute power of the L3+. Generally speaking, the pool will automatically adjust your miner's difficulty based on the rate at which it submits shares. But that can take a few minutes. So better to just set it to the recommended value from the beginning.
Also, I would like to set the payout currency to LTC.
Does it make any sense, can the pool payout in LTC?
Normally you can only be paid out using coins that the pool is currently mining. To my knowledge, LTC is not being mined by zpool. However, if memory serves me, earlier in this thread crackfoo stated that he was manually purchasing LTC so that he could do payouts using that coin. Presumably because it saves on fees for the pool itself. (miners don't pay fees directly; more on that below) There's no guarantee that this is still presently happening, and even if it is, there's no guarantee that it will continue happening indefinitely. So, do this at your own risk.
Which coin would be better to be payed out regarding the high transaction fees of Bitcoin?
As a miner, you needn't worry about transaction fees. Fees are paid not from your balance, but using the fee taken by the pool according to the algorithm (typically 2%). Once you hit the necessary threshold, and assuming you're being paid out in a coin that the pool presently has sufficient quantity, your balance will be paid in full regardless of what the transaction fee comes to on the back end.
Thanks, i got that from the website already.
Why did you put "scrypt" as an argument into the password string?
Thanks
It's redundant in this example, since you're not using profit switching. You can remove it from the password string in this case.
