So i broke something. Hopefully someone can enlighten me to where my problem lies (other than in the chair)
Please keep in mind i make no claim to knowing what the hell i'm doing, but only one way to learn, right?
2 670 GTXs, not in sli, sep .bat files for each, x64 cudaminer
On VTC, K7x32 was producing ~133kh per card. After tinkering with some different kernals received cuda error 30 and display driver crashed. Rebooted and went back to K7x32 but that now produced cuda error 30 and a crash. Reinstalled cuda and vid drivers and was able to use K7x32 with same results (133/per). Once again tinkered with different kernals (using WHQL driver instead of beta this time to see if there was any difference) and received cuda error 30 etc etc but this time a cuda/driver reinstall didn't fix issue.
Currently running K7x20 with 155kh on one card and 135 on the other atm, but what did i break exactly and how?
maybe the x32 config is at the limits of what the WDDM graphics card driver will allow you to allocate. Sometimes it works, and sometimes it doesn't. Leave away any -m1 or -C 1/2 options or reduce the x32 to something slightly smaller e.g. x30, x28
Hi Christian,
Could you give me some advices how to finetune Kepler and Titan cards for mining low-factor scrypt-jane coins? For example with Vertcoin N=10 I got:
Fermi GTX580: 130khs
Kepler GTX680: 150khs
Titan GTX780: 210khs
All of those were from autotune because I don't know how to tune card for scrypt-jane. The b x w should lower than the total warps, but the number of warps is very different even with cards of the same manufacture, right ?
There are a lot that I still don't understand.
Thank in advance, Christian.
Gute Nacht und besten Gruesse,

I assume that you are German
