YES! I answered my question by sending in a donation that I received from this forum weeks ago when I updated the block chain. Thanks again! Selling at the neoscrypt price was definitely great.

I just requested that my multipool balance from scrypt mining be transferred to my Cryptsy account. Has anyone tried sending any newly mined FTC to Cryptsy? I have turned on the neoscrypt miner but I want to know if I should wait a few days before trying to trade any of these coins. I don’t want them to end up in limbo.

That is a really good price and I wish I had more income right now. I’m more looking for a gift for my brother that can also mine then something to build a super rig. I do have a spare slot in my case though. Either way I would be looking for the cheapest. It would be nice if you could suggest something more in the $100 or less range.

I have left the latest version on overnight, I am getting am 41khash/sec on my nvidia with compute 2.0. I think that is pretty good for an older card. I can get another 7khash/sec if the cpu miner is running on 3 threads. I get 12khash/sec with the cpuminer if I run on 4 threads and mine darkcoin with the gpu.

I still am getting higher cpu usage when the gpu miner is running. I think it runs a lot more stable if I leave one cpu thread free. This might be an area for improving stability in the next version. I think that cgminer right makes everything else run slow because it is using cpu and has a higher priority.

Another option for improvement would be to increase how much cpu that cg miner uses, but just add a setting for how many cpu threads to use. It might run better if one cpu thread is dedicated to all other programs, while cgminer is hashing and controlling the gpu with the other cpu threads.

(My start options are: -I 11 -w32 -g 2 )

I already have a GeForce GTX 560 that I can use for mining.

I am interested in any suggestions as to what ATI models to look at in the used market. I am more concerned with price and hashing power than power consumption. I want another GPU to mine on but I don’t have much to spend on a new card.

I would also be interested in a Nvidia card if the price was low enough. Thanks for any help!

I am so ready for the 25th. You guys should really edit the first post of this topic so people can find the right download on the first page.

says zlib1.dll is missing

The cgminer 1.75 zip file from the first page don’t have that driver. You don’t want that version anyways. 1.7.7b is more stable and has higher performance.

Also a link to version 3.7.7b that i compiled with these instructions

https://mega.co.nz/#!FcVTEQyQ!ozPVAzZJCIGm7-nbqB3E4y1xudHI62g6YVfF_YI_GUI

I am running that version with my bat file:

setx DISPLAY 0

setx GPU_MAX_ALLOC_PERCENT 100

setx GPU_USE_SYNC_OBJECTS 1

cgminer.exe --neoscrypt -I 11 -w32 -g 2 -o stratum+tcp://atlas.phoenixcoin.org:10554 -u

-p x

I am getting 40.5khash/sec on a GeForce GTX 560.

I did notice one potential bug. When I start the gpu miner while the cpuminer is running, one of the cpu threads stops hashing. I turn the threads down to 3 and get the same hashrate as 4 in the cpuminer. Cpuminer runs fine on 4 threads doing neoscrypt if the gpu is mining x11. Any thoughts? It is only 3khash/sec but still it seems weird.

EDIT: I just tested Darkcoing cpuminer v1.3 running while cgminer 3.7.7b was also running. The darkcoin cpuminer worked better on 3 threads as well. Is it possible that cgminer needs to use a dedicated cpu thread to run?

OK I just got 3.7.7b up and running. For my command line I used:

setx DISPLAY 0

setx GPU_MAX_ALLOC_PERCENT 100

setx GPU_USE_SYNC_OBJECTS 1

cgminer.exe --neoscrypt -I 11 -w32 -g 2 -o address -p x

I am getting 5khash/sec more than the previous version and I am pretty sure there is less lag. Progress!!!

Can I get some info on the FTC testnet? I am really not liking how the price of PXC is falling and would love to point this over to a FTC neoscrypt pool.

You can give my command line a try to see if it will help you,

I use this on a Geforce GTX 560M with cgminer version 3.7.5 works well with no HW errors and very few rejects.

Drop the --thread-concurrency 400 completely from the command line.

This produced the best kh/s of all settings tested with no HW errors and many less rejects, only get a few reject

every now and then now which is normal.

Edit: almost forgot in the folder that holds cgminer you will find a .bin file that will look something like this:

neoscrypt140909GeForce GTX 560Mgtc8128w128l4.bin

This you will want to move to a empty folder if you wish to save it or delete it before running the new commander line so it can

create a new neoscrypt140909GeForcexxxxxx.bin for your new settings. If you have done quite a few different command line settings

there will probably be more than one, move or remove them all.

cgminer.exe --neoscrypt --worksize 128 -I 10 -o stratum+tcp://p2pool.maeh.org:10554 -u Pn18tqfzFNPUcFjJRq1GRYdYDJjKTBNGpq -p x

Thanks! I dropped the --thread-concurrency 400 and put gpu max % back to 100. It is running a lot smoother. It still isn’t as smooth as ccminer21. Chrome browser is usable now, but there was still a waiting for application when I switched back to the forum. I don’t have any problems with low framerates or waiting for applications with ccminer21, but this is a good start.

I got the GPU miner running on my Geforce GTX 570 getting 36.50khash/sec. Stability was an issue at first, but I noticed that one of the threads on the CPU miner that was also running, wasn’t hashing effectively. I reduced the threads on the CPU miner by 1 and stability improved a bit. I tried changing the .bat file to

setx DISPLAY 0

setx GPU_MAX_ALLOC_PERCENT 50

setx GPU_USE_SYNC_OBJECTS 1

cgminer.exe --neoscrypt --worksize 256 --thread-concurrency 400 -I 10 -o

It might have made the stability a bit better, but it was only hashing 0.1khash/sec less and stability still isn’t great. Any tuning hints? I tried changing the intensity to dynamic but that dropped the hash to 6khash/sec and didn’t make it any better.

I think you should consider making a new fork for cpuminer21 because that is the last version is the last one by the cuda team that supports compute 2.0 and it is a design goal to make mining effective on as much equipment as possible.

I am currently back to mining x11 using cpuminer21 because it is just that much more stable even though I could probably be profitable with PXC after trading. I can run cpuminer with neoscrypt at 4 threads and still get 1600khash/sec running x11 on my gpu. Most importantly though, cpuminer21 seams to drop my hashrate before it drops my framerate. If I open up something that requires a lot of GPU the hashrate drops to 1300khash/sec and there isn’t a lot of screen freezes. I can’t even open this forum to make this post while running cgminer without getting a lot of waiting on the chrome not responding. I will probably turn cgminer back on later when I go to bed, but I can’t figure out how to hash neoscrypt while still being able to use my computer.
