marucoin-mod.cl and Radeon 5xxx

[t0mpr1c3]

I tried just now and kernel marucoin-mod.cl fails with Radeon 5850 GPU. "Invalid nonce count - HW error"

There is a similar issue with the lasybear x13mod kernel.

This is the same kernel as lasybear. Which drivers are you using? Are they the AMD legacy drivers?

[t0mpr1c3]

I have tried Catalyst 13.12 and 14.4 for 32 bit Linux.

Is it a known issue with lasybear's kernel? Did you try different settings?

[t0mpr1c3]

Yes, it is a known issue, also for 6xxx. I have tried many different settings. https://github.com/lasybear/sph-sgminer_x11mod/issues/3

Does it work on the 2% donation version?

[t0mpr1c3]

I don't know. There is a windows binary that uses a large x13mod.cl kernel (~280K) which works, albeit slowly. That is almost certainly a hacked version of the girino x11mod.cl kernel. But it doesn't work with the rest of the lasybear code.

Larger kernel referenced here https://bitcointalk.org/index.php?topic=623409.msg7093311#msg7093311

Aha lasybear has done a "x13modold" fix, I will try that.

[t0mpr1c3]

lasybear x13modold fix is working for me and at least 1 other so I suggest pulling the changes.

[mrbrdo]

Can you try current version of v5_0 and use "algorithm" : "marucoin-modold"?

[t0mpr1c3]

Cool, yes I will try that when I next have a rig free.

[mrbrdo]

Thanks

[t0mpr1c3]

Working well, as far as I can tell. No hardware errors anyway.

[t0mpr1c3]

Closing this issue as the latest version has been working well for me with no problems. Thanks.

[mrbrdo]

Great! Thanks for closing.
