Hi Vehre, neo-gpumine compiled successful with the following scrypt: (I am on Centos with Cuda 5.5 toolkit and GTX750 cards)

Hi,
i have downloaded and compiled it.
But when i start i get only about 1kh/s.
DRK, Scrypt, and so on works great. But not neoscrypt...
The GPU inside is HD6770M.
Same on my windows Pc with HD6850 but there i get about 2-3Kh/s...
I think that is to poor for that GPUs.

Should i send/post anything?

If you like we can also discuss in German...

kind regards,
freeapp

Situation:

• Catalyst 13.xx installer is broken for ubuntu 14.04 and above. It can be patched but this can result in unpredictable system performance (e.g. it works, gpus lockup at startup). As time goes on more and more patches are required to work with later and later kernel versions.
• Ubuntu 14.04 does work with catalyst 14.xx drivers, however the current cgminer for neoscrypt does not work with catalyst 14.xx and results in 100% hardware errors.

Example output:
export GPU_MAX_ALLOC_PERCENT=100

3.7.7 can not work, I use AMD card.
It say :

windows 7, AMD 14.9.1.beta, gucgminer 3.7.7b, R9 270

I - 14 drops after just under 6 hours can't see card. Works so far at same settings but I - 13 (8hours)

There didn't appear to be temperature issues, it was reporting < 40 deg.

I'm going to back date to AMD 14.9.1 today to see / test if that / affects it's stability.

See

https://forum.feathercoin.com/index.php?/topic/7934-error-61-clcreatebuffer-padbuffer8/

as a starting point for a more general solution.

Mining at theblocksfactory.com and cgminer stops after 3-4 maybe 5 hours. Here's the output -TDP
will be posted next time it freezes
