Hello guys!
I'm new here and just got into Bitcoin Mining today...
The card I'm running with is a 660ti.

I tried out 50Miner and the rpcminer-mod. Both of them worked and I received shares from them, but compared to CUDAminer the speed wasn't the same, running around 110kH/s.
CUDAminer runs with up to 180, but I'm not receiving any shares at all, they all show as invalid =/

the current command line contains " -i 1 -C 0 -l 145x2 ". I'm running the newest version, the most recent drivers and turning off the firewall didn't help either... any help? =(

Thanks in advance!

Cudaminer is scrypt based...Only works with Scrypt based coins like litecoin. Bitcoin uses SHA256

an updated version of cudaminer

Great haven't noticed an update.. THANKS! I got 130 to 150-160 just by updating, also now I can quit without a driver crash

.
-m 1 (or -m 0) make no difference.

try -i 0 as well

I would fiddle with the -m 1 command with autotuning

I did this and was able to get another 10K out of my card

-m ? cudaminer doesn't seem to have such a command, or did I miss something?

an updated version of cudaminer

In case any one can use this info:

Two Msi 660Ti (stock OC)
cudaminer 2013.04.09

autotune always finds 147x2 best, so I set it myself:
cudaminer --no-autotune -l 147x2 --device 0 -t 1 -o localhost:8332 -O username:password
cudaminer --no-autotune -l 147x2 --device 1 -t 1 -o localhost:8332 -O username:password

One mines 24x7, other - only when I don't mind the desktop lag

I get around 128-135kH/s from each, which is about 20 more than anything else. Only problem is cudaminer crashes nvidia driver everytime I quit it.

P.s. I mine on coinotron and use a proxy with this:
mining_proxy -pa scrypt -o coinotron.com -p 3334
It took me ages to find one that works for LTC here: https://github.com/CryptoManiac/stratum-mining-proxy
Maybe now someone will google this and be happy

First off, absolutely great job with this cudaminer development!

For interest sake, these are some of the results i have seen:
GPU: gtx 460 (OC to 920Mhz with MSI AfterBurner)

GUIMiner: ~65kh/s
Cudaminer 9-4-2013 (56x2): ~95kh/s
Cudaminer 10-4-2013 (56x2): ~124kh/s
Cudaminer 14-4-2013 (14x8): ~127-133kh/s

Virtually a 100% improvement is truly incredible.

One thing I have noticed though, and would just like to check whether its normal or not, is that with 14-4-2013 my gpu seems to run at anywhere between 92 - 100%, giving me an average speed of ~127kh/s (changing between interactive modes does not change this). However, if i open, say, my browser while mining, then my gpu usage is consistently at 100%. This seems expected, but what is not expected is that my hash rate all of a sudden jumps to ~133kh/s!

Is this normal behaviour? Is cudaminer running faster because the gpu is being forced to run at max with the browser open? If so, would it not make sense to simply make cudaminer consistently use 100% of the gpu (assuming of course that my PC is not just crazy and likes to do wierd things

)

I only ask because i have not yet anyone else report this, and maybe I am seeing something that does not matter.

Thanks again, for all the amazing work.

He set it up to cudaminer checks for valid data. meaning a little higher CPU load to do this. It allows you to know if it actually working or not.

I am now getting 170 on my GTX 670

Tried out the 4/10 release of cudaminer
Performance has definately improved on my 600 series cards, but CPU usage is way up.
but my GTX 275s went down 10% (from 45 to 40 kh/s)
Perhaps another prefix for the old kernel w/ smaller memory moves would be in order.

Got to get to 5 posts and then you'll be auto-promoted when the next cycle runs (typically every 15 minutes I believe)

Hey man, already have twice as many posts, and still no word.

Out of curiosity, whats the most efficient miner for a crossfire-radeon system (for litecoin)?

Speaking of which, how can I get out of "newbie" mode. Already messaged in the appropriate thread, but still no word. Bleargh.

UPDATE:

Updating GPU actually worked. GPU Usage is being used as it should be, but CPU usage is still way too high. It's always at 25%, but higher when it utilizes another core. It makes the computer pretty laggy - it's a new i5 core by the way (about 2 weeks old).

Going to play around with manual config.

Anyone give me some pointers?

Thanks

Interestingly, I checked on this as well. I have an i7-3770k as well as a 680gtx. I too am getting a ~24-28% on CPU usage. So this is not an isolated incident, nor is it chipset (i5, i7) related, nor is it driver related (i am running whql 3.14)

Anyone else have any ideas?

After playing around with the settings, I can't seem to find an option that you can edit CPU threads or optimisation. If this isn't an isolated incident, I'm assuming it's coded and programmed this way?

Updating now.

At the moment I'm letting the autotune do it's work. Of course I'm entering the commands so it connects etc.

Should I try manual config?

I tried using GUIMiner scrypt by Taco, but same thing happens - just CPU Usage only.

If you have suggestions please let me know. I'll post back how I go after I update drivers.

Seem to be having similar problems to people above.

I've downloaded the latest version, the autoconfig actually works pretty nice.

I have one issue that I CANNOT work out for the absolute life of me. Either I'm plain stupid, misread something, or something I'm doing is wrong.

So first of all, everything connects fine etc it says it detects my GPU, says it's using my GPU...everything is fine at this point.

However - my GPU is not being used at all to mine. It's 0%, meanwhile my CPU is being used (25%, goes higher if I use the computer obviously). So the problem I have is the miner is using my CPU instead of my GPU.

This happened with another couple of programs I tested as well. Using GUIMiner for BTC uses GPU fine though.

Is this happening to anyone else?

update graphic drivers, also what commands are you using to launch?

What kind of performance would I get from a gtx 560 fermi?

Is it possible to allow the gpu to use system memory?

No one has tested at 560 yet. My 570 is getting 165

It is how the server calculates. Let it run for a while it will get close to the hash rate you're seeing on the client.

My client says 165, but the server says 157. latency

the server I am using took about 10 minutes or more before it was reflecting my hash rate close to what I am getting now

Yes, I understand that it takes some time for the server hash rate to match or approximate to the client end. I don't think that's the issue with me though.

1.4 hours in, and its still the same. See here: https://i.imgur.com/rmmw9xF.png

Also, I have another rig (a mirror rig which I set up for a friend with a GTX680) which is being tested on another pool with similar results.

With regards to latency, I'm on a fiber connection and my latency to the pool server hovers between 5-8ms.

Stales have gone down somewhat - now hovering between 15-25%, which is better than previously.

Ideas?
