I don't really think it's very important to spruce up the design of the sites. They are nice and simple, which is a good thing Smiley

I would however suggest you make it clear that there's an essentially "opposite" service available on each site. Maybe add something like a tab bar at the top of the sites where we can switch between CoinPal and CoinCard (or some other design that makes sense). Just so you're sure everyone realizes there are two similar-but-different services available.

Thanks for the excellent service Smiley

The -f parameter should fix that travex. I use -f 120 and don't notice any lag. At -f 60 theres slight lag. On my box the performance difference is less than 10% between -f 120 and -f 15.

This one is even simpler. But using a VGA adapter means there's zero risk of physically damaging the DVI port, so perhaps it's preferable.

Edit: Also, if your monitor has several inputs you could just hook all the graphics cards up. As long as the cable is connected I believe it should be fine, no need to actually have the screen set to an input for it to work.

Excellent service just like CoinPal. Just sold 50 BTC successfully  Smiley

I'm running at ca. 42 Mhps on Mobility Radeon HD 5650, OpenCL SDK 2.3. Best options so far: -d 0 --user=XXX --pass=XXX -w 128 -v -f 5 (I'm not sure what does -f parameter do really, I'm a dummy).
Do you think that individual mining with laptop GPU is worth it? Note: I'm not paying for the electricity.
From what I've read, "-f x" is "framerate", i.e. the program will try to balance the kernel so that the kernel is run x times per second. This means that a lower value makes the kernel run for longer (-f 5 means the kernel takes about 0.2 seconds). If your OS feels sluggish (windows lag when you drag them on the desktop, videos seem choppy etc.) you can try to set -f higher. I use -f 120. At -f 60 I get slight lag when playing back HD videos, and the performance difference is only about 6% so I would much rather have a fully working machine. At -f 120 I notice no slowdown.

At least that is how I've understood it, I'm sure someone will correct me if I am wrong.

Edit: And if you're not paying anything for the electricity and it does not bother you to have it running in the background (presumably when the laptop is plugged in!) then it's free money, so why not? If you think bitcoin is interesting I see no reason why you wouldn't mine Smiley

I've gotten successful generations using version 20110204. Yesterday and three days ago.

This is on Win 7 with HD 5870 using catalyst 11.1 (SDK 2.3)

Pretty nice service, seems to be working as described. I'm not sure if I will be using BitPenny.com or solo mining (10% will after all add up to a bit over time), but the steady generation rate is very nice Smiley

Ok I understand, thanks for the help Cryptoman and BitLex Smiley

I think you misunderstood my question. I do keep both bitcoin.exe and poclbm.exe running at the same time, what I'm wondering is what happens if I restart the programs, or reboot my computer. Will I start again from scratch or does the mining continue where it left off?
30  Bitcoin / Mining software (miners) / Re: python OpenCL bitcoin miner on: February 07, 2011, 09:23:50 AM
Aye a couple showed up when I let it run for a while longer, thanks Smiley

Another question, it's ok to close poclbm.exe and bitcoin, correct? It isn't necessary to keep them running non-stop untill a block is solved?

Hi. I'm trying to get this to work, and want to check it with the "testnet" I've heard about.

What I've done:
Followed the guide. After starting bitcon.exe -server and the .bat-file as described I get a cmd window with the hash speed showing.
I then copied the bitcoin.conf to %appdata%/bitcoin/testnet, ran bitcoin.exe -server -testnet and then launced the .bat-file as before. Again the hash speed is showing in a cmd-window, but after about 30 minutes with ~280000 khash/s I've still not gotten any messages about completed blocks. My impression was that that should happen very quicly on the testnet. What am I doing wrong?

Thanks for any help.
