[ANN] cudaMiner & ccMiner CUDA based mining applications [Windows/Linux/MacOSX]

how do i switch kernels?

the -l option allows this. By just giving the kernel's ID letter you can let cudaminer autotune for this
specific kernel. Once it found a decent configuration you can pass that with the -l option the next
time your run it.

e.g.

-l Z

for the "Z" kernel requiring Compute 3.5

I am considering giving the kernels different (more comprehensible) names for the upcoming release.

Hold on? Are NVidia cards becoming viable on price/performance vs ATI?  

Can one install Nvidia and ATI on the same Windows rig? Anyone experimented NVidia cards on PCI-e risers?

price/performance... not so much for scrypt mining. GTX 780 (Ti) cards are f...in' expensive

but very much for scrypt-jane coins with high N-factor. Here a mid range card (660Ti) can beat the AMD high end offerings.

I will experiment with PCI-e risers soon. I've ordered a 1x->1x riser, a 4x->4x riser, and a 1x->16x riser (unpowered) to play with. With a bit of Dremel magic, the card will fit into the 1x and 4x slots on the risers

Example of high N-factor scrypt coins? And what hashrate are we talking about (with 660 Ti?) for these coins.

Yacoin is the original (oldest) scrypt-jane coin and currently has N=32768 (Nfactor 14 I believe), switches to 65536 in May. An overclocked 660Ti can deliver 3.7-3.8 kHash/s. An OC GTX 780 might do up to 5 kHash/s, but the additional gain is not worth the additional price.

Sorry about all these questions but where can is there a complete hashrate list somewhere? More precisely, will http://www.newegg.ca/Product/Product.aspx?Item=N82E16814121660 really give me ~3 KHs? seems like an overkill considering that /index.php/Mining_Hardware_Comparison]http://[Suspicious link removed]/index.php/Mining_Hardware_Comparison seems to predict 1 KHs for a HD7950.

After seeing Romir's post about his watercooled 780 TI , I gave it a try with my "regular" (only overclocked) 780 TI...  

With -l Z15x24  I'm seeing ~755khash, a nice improvement over 615-620

Hey guys, hate to crash the convo here, but I've been having a lot of trouble with cudaminer today.

Ive had it running on a pair of old GTX 560 TI cards no problem for a while now, but I've now got a pair of 760s that are giving me trouble.

https://i.imgur.com/yQpI3dL.png
This is the result i get when trying to autotune. It's not always identical, it either returns with K0x0, or it returns with something like K1x6 which is accompanied by "Unable to allocate enough memory for launch config 'auto' "


I've also tried specifying K kernel, and this is the result:

I have tried a few configurations from the Googe Doc in OP, but nothing in there works either, throws similar errors

If it helps, the 760 cards are these:

Thanks in advance.

looks like the known "multi-instance support is broken in CUDA 5.5 with the latest drivers" issue.

As a workaround, try running -d 0 on one cudaminer instance and -d 1 on another instance.

Maybe a driver downgrade to the driver that shipped with the CUDA 5.5 toolkit helps. But then, a 760 card might be "too new" for it to be recognized by this older driver version.

Thanks so much Chrstian, seems to work just fine now when running two seperate instances of cudaminer.

What is the best coin to mine with GTX 570? it has  compute capability 2 and 1.28gb of ram. right now getting about 233 Kh/s

What are your settings for the overclock and temperature ? (curious and a bit jealous too ;-)

I put my new psu and put back my old gtx660 oem 1.5gb (and mod the bios to unlock the fan... allways wondered why it was locked at 65%... until I heard it...) to supplement the 780ti.
What kind of hashrate can I expect on MRC ? (right now it is doing around 210khash with the Y kernel. )

[lordaccess]

I had a GTX 780 windforce and it run at 530-540 khps and it had a boost of 1070. When I added one more I used them alone each one to test them and had the same specs and speed.

Since I can't use both in one cudaminer (it crashes) I use two of them. The problem is the first now only reaches 960 Mhz instead of 1070 and the speed dropped to 470 khps... My cpu is AMD FX 8350 and my PSU 850W. Why this happens?

Also when can we expect a new cudaminer for windows? (8.1)

Mate thanks for all the hard work you put. If you have a paypal donate address do message me.

I have a GIGABYTE GV-N780GHZ-3GD GeForce GTX 780

Can you throw up the compiled version of cudaminer.exe some where ?

[ManIkWeet]

I compiled an older github version of cudaminer to get my hashrate up a bit more (4.15 instead of 3.90) and I am glad I did...

YACoin that is

How to compile these builds on windows? I'm a noob in that.

Can i mine scrypt-jane on a GTX 570?

[Wipeout2097]

Sorry for the offtopic, I understand that this about the miner, but this ends up being the "go to" thread for who is interested in mining with Nvidia. There's a thread elsewhere that proves ATI cards are affected by vram latency and someone offers to optimize their bios. I wonder what kind of performance would one get if Nvidia cards had such firmware optimization. Is there any software that allows one to experiment with memory tweaking or allows bios modding currently? I remember about Nibitor from the 8800gt days...

I'm running at 1164 with -90 to memory at 106% TDP, the card is at ~64C.  I can push a little more but it sometimes gets unstable. I'm debating flashing a new ROM on the card...
