cuModuleLoad 301 error GTX 750 ti only on some hash types
#1
Shocked 
Getting the GTX 750 Ti to work is not really the issue, I can run through most of the benchmarks, it's just certain hash types that cause this failure. Primarily the unix based ones.
Like:
500 = md5crypt, MD5(Unix), FreeBSD MD5, Cisco-IOS MD5
1800 = sha512crypt, SHA512(Unix)

However
1500 = descrypt, DES(Unix), Traditional DES
Does work, but seems really slow for being so old
Speed.GPU.#1.: 14306.9 kH/s

This is my result with just MD5
Speed.GPU.#1.: 596.5 MH/s

Anyway here is my output on trying to do a sha512crypt (unix)
Code:

What is your driver version?
#3
Driver version : 334.21
#4
descrypt is slower than md5, around 90 times.
#5
on nv
#6
Any thoughts on the failure to load module on only certain hash types?
#7
I'd say it's missing the bzero or markov kernels. Did you remove some of the kernels in the kernels/4318/ directory? It's part of the archieve so it must be something like this. If unsure, just unpack it again
#8
we've worked on that issue on irc and found out a bug related to sm_50. If you have the same problem, come to IRC and tell me or wait for v1.21 release.
