Hi, can somebody give me a hint where to find solutions for these problems,

Upgrated to win7 to 10 because i coulnd´t get 6->7gpu work. With win7 mining rig where rock solid with intensity 5

after upgrading first problem was that gpu3 invalid data, lowered intensity to 3
Now i´m rejected shares all the time

And there were no hardware changes, Only adding 1 gpu more, All gpu´s are 280x
drivers 15.12

How much rejected share is ok? 0?

My rig setup
Claymore's ZCash AMD GPU Miner v12.4
Windows 10
7x280x
8gb ram
MSI Z97 Gaming 5
2x psu
1000w
860w
normal pcie risers


Thanks for your help

Installed win10 and all cards worked straight away, no mod needed...

Still error 43

Can somebody help,
I did get 6gpu working with this mod but added 7th gpu and it shows error 43. Tried to force the mod again but it didnt help.  Pci is set to gen1 latency 32/64.
Also removed drivers with ddu an re installed them, no help..

Hi,
Can somebody help me with adding fifth card to my mining rig, Problem is that Windows 7 find all cards but one is with the yellow exclamation mark.
Device status: Windows has stopped this device because it has reported problems. (Code 43)
all cards are r9 280x execpt one whitch is 280.

When disconnecting any card everything works fine.


Allready done,
Uninstalled all drivers and added 6xgpu mod and re-installed drivers ([Guru3D]-radeon-crimson-15.12-with-dotnet45-win7-64bit)
bios settings changed PCI-e ports from auto to GEN1 and then 8x4x4x (tried also gen2,gen3)
changed new riser
Changed riser to diffrent pci port

Is it possible to even get 5 gpu´s to work with windows 7?

Help is really needed

Thanks, Pesuvati
