@claymore One of my systems has an AMD Pro Duo and I am getting invalid shares from GPU 1. It is not hot and not overclocked. Using Windows 7 64bit with crimson 16.9.2. I have reinstalled it a few times. Is there a setting in Claymore I can change that would effect this ? I am on 7.1.

Thanks!
waiting for new version (16 card)
the test results I will inform

wow nips - the most I got was 7 using the PCI riser multiplexor.

Are you using multiple of these or you have some sort of sorcery motherboard that  is top secret?

 

Have the same bug on rig with 3 x 380x and 1 x 270x. 270x shown like Tonga.

Anyone mining on hd7990 and have this problem?

LOL, one of the coolest things I have ever seen!  

@Claymore: a max of 16 could be insufficient 

what crazy PSU did you use?

1600w x 2?

x 3?

So this runs a custom OS?
Or linux and there is no card limit under linux?

only 8 GPU possible to run on win7, if more - BSOD when loading video drivers,
6xGPU mod not helpful
