Regarding cryptonight:

for the ccminer cryptonight kernel it seems like the level 2 cache is a big deciding factor.

750ti   / 2mb l2 cache
960     / 1mb l2 cache
970     / 1.75mb l2 cache
980     / 2mb l2 cache
Titan X / 3mb l2 cache (anyone got one yet  Shocked )



But how come the amd cards are that fast with only 768kb for the 280x or 1mb for the 290x??
Is memory bandwidth and latency that much more important for this algo?

I miss when crypto was about decentralisation.
Is there a specific version of Cuda I should have installed?
If you just want to use the binaries you only need the current driver.
If you want to compile it yourself you need the CUDA Toolkit 6.5.

Thanks!

1 bottle of 40% thai whiskey costs 0,0088487 BTC
Suddenly, I want to go to Thailand. I'm afraid I might stay there though.

But thaiwhiskey is made from rice and not potatoes. Doesn't taste as good as what we are used to..
Prefer beer.

Today I ate a bigmac at McDonald's 0,01453715 BTC.

More expensive than 1 hour of thai-massage.

And in the tourist areas you can multiply the prices by 3-5
sp could you ask them how much electricity cost?  plz  Wink

comparing v43 vs. v44 for my gtx750(non-ti) (windows binaries from github)
x15: 1966 vs 1976
x13: 2272 vs 2270
x11: 2886 vs 2883
quark: 5700 vs 5660
qubit: 4418 vs 4419 (with drops)
lyra: 882 vs 881
So, only x15 gain for me

Your junior 750 is beating some 750ti's on standard clocks.
I think it's time to implement a command line switch for the gpu-memspeed and the gpu-core clock. Some of the algorithms needs a good memoryspeed/corespeed factor, and some of the cards are not configured optimal. I had a quick look and found support in the NVIDIA api to adjust the clocks.. Will have a look when I get back from my vacation..

In the north east thailand:

1 hour of Thai-massage costs        0.012641 BTC
1 bottle of 40% thai whiskey costs 0,0088487 BTC
1 noudlesoup meal with meat and clean ice water in the resturant costs 0,0029495  BTC

nice Smiley ...

would be ideal if we could manipulate the clocks ( mem and core ) from the commandline ...

sounds very cheap over there ... and very nice Smiley ...

might even be able to buy property too with btc ... i wonder ...

Wink ...

#crysx

Linux command line to change clocks on my laptop, GTX850M, this is in my launch script.
optirun nvidia-settings -c :8 -a [gpu:0]/GPUGraphicsClockOffset[2]=80 -a [gpu:0]/GPUMemoryTransferRateOffset[2]=300

If you dont run optimus/bumblebee to switch on the second graphics card you dont need optirun, :8 is the display number, you need to have coolbits set in your config for it to work.

I am going to comment on this.

Those are some awesome prices. Here 20x that and you still don't get a massage.

Enjoy.

unfortunately with the latest release intensity 21 now crashes my cards (GPU GTX 970, two of them in SLI)
previously it was fine, now I am setting it to 20 meanwhile

try -i 20.9, 20.8, 20.7....  etc until you get the optimal rate

Note that the optimal intensity might vary from build to build. the default should not be to bad. If you find a setting that is optimal, please tell me and I will set it as default

ICO? Not even once.
I read the last few pages, but I didn't see:
What hashrate does a Nvidia 750Ti card make on X11 with the latest miner/binaries?
With what settings, and possibly at what consumption (watts)?

Thank you

standard settings with stock clocks and 64 bit compile using sp's latest we get around 2840KH using x11 ...

thats per card - gigabyte 750ti oc lp ... and they consume around the 60W mark per card ...

#crysx

For reference, I get 50W per card with TDP increased BIOS and +140 Mhz on the core on the same cards on gold PSU and hashing at 3166 kh/s. I always use 32 bit builds.

I tried changing 320 to 256 in shavite ... no good ((
I have manual set intensity in batch files e.g. - I 19.3 tuned once some time ago ... hope it doesn't interfere performance of new builds ...

Try to reduce the launchbound in Shabal from 320 to 256. If you have time revert some of the change sets to find the one that slows down.
There are to many changes for me to test ((
Did you mean shavite to change TPB from 320 to 256? (ccminer-windows\x11\cuda_x11_shavite512.cu)

Yes. The 750 has 512 shaders while the 750ti has 620. A threadcount of 320 was faster on the ti but proboby not on the 750
And the 980(?)
