Hi,

I've just updated my miner repositories on Github with increased scratchpad buffer size.

You can compile it yourself or grab a binary release for Windows x64
https://github.com/mbkuperman/cpuminer-multi-opencl/releases/latest

Scratchpad is getting close to 256 MB limit so don't be late in case you are using my miners (and check the size if you are mining with something else too).
