No longer neded 5830s. Would prefer to ship in a single lot and the price above assumes this. Will ship to the lower 48 United States and Canada. I am martok604 on #bitcoin-otc for rating verification.

Payment via BTC or Dwolla.

Hello all,

I am getting the error in the subject quite often when I attempt to send BTC. It isn't exact but is approximately every other send. For the test, I am using vanilla bitcoind from git. Though I have tried using JGarzik's minkeypool patch with the same results.

Here is the RPC session:

Anything I can do about this one?

Hi,

I have one client getdifficulty reading 434882 and another (git) at 434877. Gribble thinks 434882 is correct but why the divergent readings?

Hi,
My payout script generated a parse error on around 30 transactions in a sendmany call. All amounts were >= 1 BTC. So I manually had the script process one transaction at a time, still using sendmany and it worked though with many more transactions.

Is there a limit on sendmany recipients or perhaps the size of an RPC payload to bitcoind?

Hello,
Has anyone successfully underclocked a Radeon 6990 under Linux using amdoverdrivectrl? If so, would you mind sharing your overdrive profile?
No matter what I do, an underclock doesn't take. Here's what I currently have:
<?xml version="1.0" encoding="utf-8"?>
<OVERDRIVE_PROFILE>
<PERFORMANCE_LEVEL level="2" gpu="83000" mem="30000" voltage="1120"/>

Hello,

I would like to announce the availability of the Continuum mining pool. It is new and could use some testing. The pool runs with no fees and is aimed at more serious miners, though all are certainly welcome. The pool supports long-polling and should provide good connectivity to north-american miners. It also supports monitoring of miners; if your miner hasn't submitted a share within a defined period, you will get an email or Twitter to that effect.

Usage:
Simply connect your miner to continuumpool.com port 8332. Use the bitcoin address to which you would like to be paid as the username and use any password. I recommend that you use a different Bitcoin address for each worker so that balances and uptime monitoring can be set per-worker.

The pool provides an RPC interface. It does not provide a web interface, though anyone is welcome to write one. To use the RPC service, connect to http://rpc.continuumpool.com:8330/rpc and use the following methods.

balance(workeraddr) Returns confirmed unpaid balance
balancecurrent(addr) Current round balance
roundstart() Returns the time of the start of the round.
monitoradd({worker => 'workeraddr', 'contact' => 'mailto:me@mydomain.com', 'sharetime' => '5 minutes', 'name' => 'some descriptive name'}) Adds an email monitor. If the worker hasn't submitted a share in set time, an email is generated
monitordrop({id => monitorid, worker => 'workeraddr'}) Cancels a monitor. Get the ID from the generated email.

Once again, testing and feedback would be greatly appreciated.

Hi all,
I have an MSI 870 mainboard with a 5970 installed. poclbm -d1 does the right thing but -d2 either gives verify  error: check hardware or it'll hash but only at 170 mhash and cuts -d1 in half as well. So it's almost like it's using the same GPU for both processes.
I have tried
aticonfig --crossfire off --adapter all
with and without restarting X. Though --lscs still lists crossfire as enabled after an X restart.

Anyone using the MSI 870 and have this working. Happy to send BTC for a solution.

Hello,

I emailed support@bitcoin-central.net about this but I have BTC stuck at BC and can't get it out (500 server error). Any way to get hold of this guy?

Hello all,

Recently I sent a btc 1.00 transaction as a tip to a helpful forum member. However, I was charged a 0.01 transaction fee on the send even though I have paytxfee=0.00 in bitcoin.conf. I was using "bitcoind sendtoaddress" so didn't have an opportunity to see what the fee was or confirm it.

From the wiki:
Transaction fees are voluntary on the part of the person making the bitcoin transaction, as the person attempting to make a transaction can include any fee or none at all in the transaction. On the other hand, nobody mining new bitcoins necessarily needs to accept the transactions and include them in the new block being created. The transaction fee is therefore an incentive on the part of the bitcoin user to make sure that a particular transaction will get included into the next block which is generated.

If they are optional, how do I opt out? I get that I may need to add a fee if I am sending something time sensitive. But this was just a tip. He'll get it when he gets it.
