[Support] Hello! Mining Problem on windows.
-
Hi!
My name is Fabio and I’d like to start mining Feathercoin!
I have a very little hashpower while I’m using my pc, but I’d like to use it.
With neoscrypt, my cpuminer has no problem. I have problems using gpuminer with Neoscrypt.My video card is an ATI HD4670, 13.4 Catalyst Driver.
Can I mine with this gpu? Thanks in advance.[2014-12-11 12:42:00] Started cgminer 3.7.7b

Hi and welcome to the community as far as I can see you should be able to mine with that card even if its a low hashrate.
I’m moving this to the support section so others can benefit from any answers you get.

I think ATI HD4670 can not work , because OpenCL kernel can not support HD4000.

Hi Lizhi,
an observation: I’ve used cgminer( scrypt algorithm ) with my gpu with approx. 38-40 Kh/s. Do cgminer use OpenCL too? If the answer is yes, why can I use cgminer with scrypt but not with neoscrypt? Thanks in advance, I’m new in the world of mining, and as junior programmer I’m very interested about it.

Support for the HD4600 series was included in OpenCL_1_0 as far as I can tell. (https://www.khronos.org/conformance/adopters/conformant-products#opencl)
Try using sgminer 5.1 with Wolf0’s kernel. Its producing neoscrypt hashrates well above cgminer for most AMD cards so far.

Your miner says it clearly: no support for cl_khr_byte_addressable_store. This extension is required by all current NeoScrypt kernels for the FastKDF part and the HD4000 series doesn’t support it. The situation may change in the future though.
