LaSeek has been running simulations like crazy, they come out fast, but after synthesis they run very slow so far.

Does anyone else get about 5% invalids using the new cgminer and high thread concurrencies?  Gonna switch my 7950s back to reaper for now until I figure this out.

These are theoretical numbers...  laSeek has been busting his ass to try to get kilohash/second rates into the double digits with inexpensive FPGAs.  The trials in altera FPGAs were a trainwreck.

The problem is that even with a large number of slices, you will run into the problem that
1) Memory bandwidth in FPGA devices is poor comparative to a GPU.  For on-slice cache it is 10-20x less than that of a GPU, and for off-chip memory it is about 20-40x less than a GPU.
2) Clock rate of FPGA devices in general is lower than that of GPUs.

You can resolve 1) by chaining memory interfaces in a multichip configuration, but that's a lot of hardware customization.

Christ, I was thinking about buying one, but for that price I can get tons more litecoin mining rigs (enough to make about $150 per day) today.

Make sure you have speed step/cool and quiet disabled in the bios to prevent throttling of the CPU at low usage, sometimes this can screw up mining

Use it in windows command console (cmd.exe) or just use my guiminer (which doesn't permanently alter your registry/environmental variables)

See sig thread

Memory is important, but on motherboard and on card.  So is memory speed.

CPU speed is also important, but you only need one core at about 2000 MHz (make sure you turn speed step etc off for fastest mining)

ADL is the ATI Display Library, which is used by cgminer miner to do things like set clocks and display temperatures.  If can be disabled by adding "--no-adl" to extra flags in the cgminer tab, but you should not have to disable it.  Make sure that you have both AMD Drivers and AMD APP SDK installed.

Also, guiminer-scrypt does not yet support CPU mining, this may be changed in an upcoming release.

Can confirm this works, although it's kind of a sloppy fix but only because of the way windows does environment variables.

Added to my guiminer setting the env var locally instead of globally when running cgminer with high thread concurrencies

Added version 0.03 alpha, which includes enabling high thread concurrency usage in cgminer

This feature would take a lot of time to implement and isn't in the works for now; the easiest thing would just be to stop the miner, lower the intensity, then raise it again later when you're doing something else.

To mine litecoin and bitcoin you'd need to have this guiminer and the original bitcoin guiminer open at the same time, then make a cgminer tab in both programs and run them.  I have no idea what kind of hash rates you'll get with each, though.

I'm not totally sure.  Your configuration above looks totally normal

One thing to try is to run cgminer outside of the gui.  To do this, open the console in the guiminer and then hit start on cgminer.  if you go back to the console, you will see a command for cgminer, something like

Go into the start menu and type "cmd", then open a command console.  Copy the command above starting with "C:\....", then right click on the command console and paste it in.  Execute the command and hit enter.  Then, let cgminer run for a while and see if you see the hash rate decreasing in the actual program.  If this is the case, it's an issue with cgminer and not with guiminer.

Okay, I will try this and then add the shell command to GUIminer if it works okay.

It costs 0.10 cents right now to make 1 USD with an Avalon ASIC through BTC, and about 10.0 cents to make 1 USD with a GPU through LTC with electricity at $0.10/kwh.

Probably as time goes on, mining LTC with a GPU will be much, much more profitable than mining BTC with a GPU.

This issue is sometimes due to the wrong platform not being detected, try --gpu-platform 0 or --gpu-platform 1 in extra flags

This will be fixed in 0.03

Please show a screen cap of your configurations and any console output and I'll see if I can figure out what's going on.

It'd also be helpful if you post the contents of C:\Users\you\AppData\Roaming\poclbm\poclbm_scrypt.ini

I doubt it, more like difficulty up.  With an avalon it only takes 0.0010 USD of electricity to produce $1.00 USD at the current difficulty.

Either price is going to go down in the coming months, or the network hash rate/difficulty is going to increase 100 fold.

No problem. C:

^^ It's easy to make money if you can accept a little risk...  I have used the increase in price to purchase more mining rigs with my hoarded LTC and further drive the network hash rate up.  In the meantime, my profit in general increases if I sell daily because I have so many more cards mining right now.

I realize now that it's a never ending cycle of tight reinvestment into more gear, hoarding what I can, and selling a little to keep up with electricity.  But so far it's been extremely profitable for me and I expect more people to hop on board as time goes on, especially as ASICs become widespread.

The $1500 I spent for a 2 MH/s rig 6 months ago has now netted me about $11k after electricity, plus I still have the hardware to sell.  I can't wait to see what 6 MH/s of new rigs will net me.

What the terminal states and by the number of shares accepted by the pool.  The pool is subject to variance and usually averages performance by the last 5-10 minutes, so it will appear low for the first 5-10 min.
