Re: Claymore's Dual Ethereum AMD+NVIDIA GPU Miner v9.8 (Windows/Linux)

hello
i have a big problem with the last version and all over miners. works with 3 cards and when i want to put 4 gpu cards on my rig, it crashes...
all the same cards, Under win10 fresh installed, AMD driver 17.4.4, stock cards, psu 1200w seasonic prime on asrock H81 rev2

risers are ok because:
- gpu 1+2+3 => ok
- gpu 1+2+4 => ok
- gpu 1+2+3+4 => ko...

claymore start well and detect the 4 gpu's but crashed before to start mining, just after GPU detect.

please help me !!

- Make sure the card is not sharing power with another card
- Make sure each riser not sharing its power with another riser
- Run all cards on stock BIOS and stock seetings
- Uninstall MSI AB or similar software
- Run DDU in safe mode
- Reinstall AMD driver, the latest
- Run Claymore with minimal settings -cvdcc 1000 -mvdcc 1500

Share results and screenshots from GPU-Z

hello,
i did everything and its still the same problem... im running now Under 4 cards and it's crashing.
Under GPUZ i don't see any problem and all the cards are detected. no time to post screenshots for the moment.
any idea ?

i put under 2 cards, i've got another problem about drivers, perhaps it's my problem, with 2 cards, on pciexpress 1 and 2,
one cards is Under Crimson 17.7.2 / whql /win10 64 drivers (opencl ticked)
and the second one is only whql / win10 64 drivers (opencl not ticked)

Did you run DDU? be honest...

of course i did it !
i had to go to my job this morning, not enought time sorry.
here is the screenshot with one card, it seem that there an exclamation behind my card. Conflict between windows drivers and AMD driver ??
do i have to use DDU each time i add a card and re install crimson AMD drivers 17.7.2 ?

i tried to use simplemining and it does not work well at all... only 10mhs with 3 cards and gpu core often low at 300 instead of 1236, really strange. I had the 300mhz issue yesterday and it was afterburner causing the issues. I pressed the reset button in afterburner and the clock went back up. Some say online to remove afterburner and reinstall it.

I believe you have two problems. First of all you need to reset all you afterburner settings if you are using it. Or if you are using any other overclock software just uninstall it until you get things sorted.

Then your 4th card is probably not showing up because of the motherboard bios. You need to make sure above 4g decoding is enabled. Some mobo brands call it something else. Some don't support it.
