Overclocking memory speed helps a large amount with scrypt. Also set powertuner to +20.

I've been a bit scared to go as high as 1525 but maybe I should try it when my new power supply arrives..

Yes seems to run great. Been getting about 530K/s at I 17 for ltc, I'm overclocked some on engine and memory. Would have to get home to check exact figures. Powertune saves power by dynamically lowering clock speed, nothing to do with voltages, as far as I can tell. Ltc farming can get a huge boost from overclocking memory moreso than gpu, it seems for me.

One thing I just learned tonight is you need to set powertune to +20% to in effect turn it off. Otherwise it'll drop your clock speed on and off to reduce power usage. Just a tip.

rethaw, I didn't bookmark them, but I re-found these:

You can do the transfer mode right to a bitcoin address, and use your deposit address for BTCe. After 3 confirms it'll show in your balance.

This is exactly how any sort of purchase in a foreign currency works. You pay money out of your account in USD, it is converted to the destination company's currency, and they deposit the money they receive in their native currency.

Assume Euros were trading 2 Euro for 1 USD. You order something from France for 100 Euro. You use your debit card to pay for it, and 50 USD comes out of your account. The French company does not have 50 USD sitting around, they have 100 Euro in their bank account. The currency exchange is handled by one of the intermediate banks.

A month goes by, you decide you want to return your product. One of three things might happen.

1 - USD/Euro hasn't moved. So you get 50 USD back.

2- Yay, USD is weaker vs the Euro at 1:1 now. So you get refunded 100 Euro which is converted to 100 USD. You came out $50 ahead.

3- Oh no, USD is stronger vs the Euro at 4:1 now. So you get refunded 100 Euro which is converted to 25 USD and you lost $25.

In all three cases, the company sold and refunded 100 Euro. They aren't engaging in currency speculation or market making. The funds you sent them are converted to Euro to do the sale. This is why large companies making large overseas orders will buy hedges against currency rate changes, so your costs don't skyrocket when the next bill is due because your native currency has grown weaker vs the foreign currency.

In this case you purchased a good from a company selling products in USD. The currency you used was bitcoin. It was converted to USD for purposes of this transaction based on the going exchange rate. If you want a refund in bitcoin, you get refunded in USD and it will convert back to bitcoin (or Euros, or whatever currency) at the going exchange rate.

If BFL didn't do it this way, it'd be dangerously irresponsible. They'd be using your pre-order funds to engage in currency speculation instead of producing hardware. What if the value of bitcoins dropped to 1/100 from the time you placed your order, and they were holding bitcoin not USD? Now the (say) $1500 USD you paid in bitcoin is only worth $15 when they convert it to USD to pay their suppliers, payroll, etc. They'd be bankrupt in a moment. And I'm sure history is full of companies that went bankrupt because of a massive overseas transaction + rapid currency movement + lack of hedging.

Heh. One way the bet ends up "true" is if they are shipping the orders and so no refunds given because they gave you hardware instead.

I run a cpuminer on the free EC2 since, why not, it's free and fun. But I've seen 3 different people mention they are working on new cuda code that is 2x-3x faster than current cgminer on nVidia GPUs. Still won't make the Tesla EC2 worth while, but it's closer.

I was hoping http://ppcpool.bitparking.com/ would choose a provide risk-free payment system and come back online. Doesn't seem to be happening. So if you get going I'll certainly rotate you in with coinotron, they go offline a bit too much and they are the only pool I've got...

Coinotron shows 48.2 GH currently.

Is there a reason coins can't just have the reward adjusted dynamically instead of the difficulty of finding a new block with a static reward? Then blocks can keep flowing quickly for transactions, and just the new block reward go up/down based on the desired new coin generation rate.

Yeah it's be nice if there was a simple consolidated list on their site for all coins/servers/ports/settings. Glad you are mining!

Is the core code for a basic GPU miner different than cgminer? I thought there was a lot of overlap in the code bases between the two projects, but honestly have no real idea. I did try 3.0.0 last night though and have to say for the same .conf I used in cgminer I seem to have a higher long-term average hashing speed (not a huge amount, but noticeable).

You are connecting to the wrong port, so the shares you are submitted all all invalid for the blockchain.




And like Keninishna said, there's no stratum for PPC. Connect to http://coinotron.com:9322 instead and I bet you'll start seeing shares appear.

Would like to request a feature. If you launch with -c filename.conf then change that to the default filename when going to Write Settings.

Does coinotron show valid shares were accepted? Is your minimum payout level at the minimum or higher they specify on the front page chart?

Man, so many new languages I've never even heard of, lol. I'm obsolete. Everything I ever did was in C, C++, PHP, or Perl. Touch of Java. Never learned any Python.

I like how your system doesn't use a password, just links to a hash you can't change. The Eligius guys take it a step further and your payment hash is your username, no pw or accounts.

doublec, did you roll your own front end/back end or were you using existing packages? May I ask which one(s)?

Thanks.

Edit: If you enjoy running the pool and doing the front end part of things, you might consider this payment system:

Zero out of pocket/risk to you.

Great idea, thank you. What I ended up doing was starting up a local ppcoin server and putting into cgminer as a second pool in load balance mode. So in theory I'll solo mine if coinotron is down. In theory...

Speaking of which, can I have pools for multiple SHA-256 coins in cgminer at the same time? I'm guessing the longpool/stratum notifications would mess that up. Like say, if I added a PPC and a TRC pool, if it'd individually work on the work units assigned without any weird issues.
