Hello guys!
I was wondering what kind of parameters I have to set up to optimize the miner for my GPU...
It's a 660ti (GK104) and the current parameters are "-gpu -aggression=13 -gpugrid=128 -gputhreads=512".
Unfortunately the GPU is only running at around 60% power, reaching around 95-98MH/s.
With cudaminer (scrypt, I know) I was able to get nearly 180kH/s with 100% power usage.

Could anyone please help me out...?

who runs a mining help group or site? that could be profitable

Its all about the Gold

Any way to have a log file saved to computer much like cgminer can? If so , what is the command please.

Thanks.

I have never test the miner with PPCoin. It looks like many rejected hashes.

High rejection rate can't exlpain why the hash rate seen by the pool agrees very well with the rate what miner prints out.

I am using this to mine PPCoin on coinotron. The setup is the same as in my post #195 . There were 144 this

Code:

Found nonce 3FD7CA5E
2013-05-05 13:54:53 Found Hash!

within a period of 100 minutes. But coinotron only reported 19 shares. What is really strange is that the average kh/s reported by coinotron agrees with the hashrate printed by the miner on average. That means the rate at which my miner finds shares seen by the pool is correct, but the "Found Hash! " is 7-8 times too often. Why is that?

EDIT: earlier port #

I just tried this on c2075. The result agrees well with the c2050 card (107mH/s). There is fluctuation (from 70 to 140).

The fluctuation come from you "slow" card. The summery is build every 30 sec. It can be that some times the count goes to the next or previous intervall. A drop is also possible if you get no connection to the getwork server. The best is to use the http://mining.bitcoin.cz/mining-proxy-howto stratun proxy. If you use them you get better and smoother results.

can anyone list a rpc mining settings and overclocking settings for each nvidia cards starting to 600series? it might be very helpful to others who wants to maximize the potential hashing power rate of the nvidia cards. Grin

btw im using 660 ti

If I run ufasoft or cgminer I get 98mH/s. So there is ~10% improvement. Thanks.
btw I find a 100+% improvement of LTC mining speed with cuda optimization here https://bitcointalk.org/index.php?topic=167229.60.

I'm undermining of coinotron with protocol PPcoin and I noticed a problem, I bring my gtx 560 to 918 mhz and I get 80000 kh / s on the site but I have always been a rate ' of 57.8 mh / s, sometimes I also marks more than 200 mh / s. and ' a problem with the site, or mine? ? thanks

edit: I forgot, many times on the site tells me 0 mh / s.rpcminer but taxis always on 79/80000 kh / s

I've been able to get up to about 190MH/s out of a normal GTX 680 but its still really not worth it. You can get double that for a card half the price.

Hello, im getting 0mhash/s on both psychocoder-germany and cdmackie. I have no idea whats going on.

Update drivers?

Thought i had done that, turns out i hadnt, works fine now thanks. Was 310 and upgraded to 310-updates , ubuntu raring, case anyone else suffers.

Edit: Issue has returned, investigating. also a crash.

As in, I copied the files from that link into the bin folder and tried running the cuda win32 file from there.

If you could build the latest one, that would be appreciated. I'm not as advanced in programming and IT as I used to be, given it's been a good few years since I last tinkered around with PCs. I'm used to just unzipping files into directories, then clicking on the appropriate executable file and away I go, like how cbuchner1's CUDAminer app works.

I meant, specifically what errors are you getting

Anyway, I have built the 32bit versions and put them in:

https://github.com/cdmackie/rpcminer-mod/tree/master/bin/win32

Thanks! Ok, just tried running it and I got the following error message:

C:\Mining\RPCMIN~1\RPCMIN~2\bin\win32\RPCMIN~1.EXE
The NTVDM CPU has encountered an illegal instruction.
CS:0e4b IP:0528 OP:63 6f 6e 74 65 Choose 'Close' to terminate the application

I'm running a GT 220M, so that could be an issue. If it also helps, it uses Compute Capability 1.1. Would be nice if I could just take the relevant code from cbuchner1's program and adapt it to something like CGminer, which I know normally works fine with my laptop, but my C++ programming skills are too basic at the moment to be able to do that.
