Hi Trolloniex, I’ve got 6 cards working fine on a MSI Z97 Gaming 5 motherboard (OS Win8.1 Pro) under AMD Crimson 16.11.5. Cards are: 2x R9 Fury, 4x RX480\_8GB. RX480\_8 cards have the vdrop+.rom bios flash. R9 Fury stock. Yesterday I spent a few hours trying to get 16.12.1 working with all 6 cards and could not pull it off so went back to 16.11.5 AMD display driver. On a different machine with just 2 cards, RX480\_4GB, I can see the bump up in hash rate using Claymore 9 + 16.12.1. My question to you is have you applied Claymore 9 + 16.12.1 drivers to a 5+ card rig, and if so, what did you do to get that to work? I have Testsigning ON, I tried manually signing the 3 key ATI/AMD \*.sys files, etc. Thanks, and I always appreciate your comments. ~ Nestor ---

You need to run them in my basement up here at 8000ft altitude - lol My 480s are all mining at 59 degrees with the fans off 😃 ---

i had to disconnect all cards except the one in PCIe 2 to install the driver then restarted twice to get the driver properly initialized after that shut down the machine and added the other 6 cards booted and it took about 15 minutes for them to get initialized after another 2 reboot the system was up and running MSI Z97 Gaming 5 with 7 MSI RX 480 did not see any hash improvement but i only installed the drivers and not the relive software ---

i changed the pci setting to Gen2, 8x4x4x and 96 latency and no issue since then with 7 cards to be precise: no issue with Claymore miner, gpu drop and crash every now and then with optiminer v0.6.0(have not tested the new version as claymore is running flawless) ---

I use the same config Gen2 and 96 latency for driver I have installed 16.6, also disabled Windows update. ---

Thanks. The bios change did the trick plus I discovered one bad riser. I have 6 GPU running now on MSI Z97 ---

Hi Dubie, After you get 4 cards to work on that MSI Z97 motherboard run the program 6xGPU, then shutdown. Install 5th card, reboot. If 5th card recognized, update the display driver until you see Radeon ™ RX 480 or whatever in device manager, but DO NOT shutdown/reboot until you run 6xGPU again. Also run CCleaner and check your Registry for errors and fix. Then shutdown. Reboot to make sure all 5 cards are recognized in device manager. If they are, shutdown and install 6th card. Install AMD driver for 6th card, run 6xGPU again before shutting down, run CCleaner, check Registry for errors. Then shutdown, reboot. If on reboot all 6 cards show up correctly (no exclamation points, no question marks, no generic ‘microsoft display adapter,’ you should be good to go. Also, read about BIOS changes you need to make (GEN2, higher latency value 96, SATA set to IDE, not AHCI, secure boot set to “disable” etc.) ---

glad you got it running those risers seem to be a real issue i had to order 16 risers to get 7 working and they weren’t the cheap cheap ones you can buy, each was around $8 v6 the ones with the yellow pcie slot seem to be the most reliable, 5 out of 5 working the black pcie slot 2 out of 6 working the blue pcie slot 4 out 5 working ---

All of a sudden all I’m doing is finding shares, but only a few are accepted. Was working perfectly fine 30 min ago. Tried rebooting rig, same result. On Flypool. Anyone else seeing this? ---

my share count seems to be down by 50 in the last few hours looks like claymore is producing the same amount as usual Flypool issue? > **[Screenshot](https://prnt.sc/dhsd23)** > > Captured with Lightshot ---

Thank you for your advise. The fans on those two cards are around 91%. I was just a little concerned that 79 would be too high. ---

Claymore latest couple of updates pushes GPU so they use more power which generates more heat its a good idea to setup your rig near a window and desk fans also work to move heat away from your rig that will drop temps,your GPU will start throttling at 90c on most cards to stop them getting damaged but 79c is fine and will not cause any damage if concerned you can ran fans at 100% to drop temps although this is hard on fans and will lower there life expectancy I buy GPU’s with hot swap fans like sapphire nitro or xfx black edition as they can be swapped without sending back and software checking can tell when there is a problem, mining ether fans are on 100% as cards are pushed to max and my mining room sounds like a wind tunnel lol ---

I have (5) Sapphire Nitro Radeon R9 Fury’s running on my new rig. They all show up fine in device manager. When I run Claymore 9, all but 1 card gets around 330 sols/s as expected. The one card only does 95 sols/s. Could this be a riser issue as well? All cards have the latest drivers. Not sure why all would work fine but one. Afterburner shows that card doesn’t go past 300mhz while the others jump up to the default setting while mining. Any help is appreciated? ---

make sure all cards are set to defaults in watman before using any other overclocking software and has your power supply enough power for all cards,I run nitros and furys but not in same rigs, sounds like driver issues you can uninstall bad card in device manager then scan for hardware changes which will re install driver or a reboot will do the same ---

Are your three GPUs directly mounted on the motherboard, side-by-side? If so, two of the three won’t have adequate ventilation, and the thermal control software on those boards will reduce the clock speed to prevent overheating. The third card is not affected as it is getting adequate cooling airflow. You can use MSI Afterburner software to check the clock rates. If this is your configuration, you might need to convert to risers to get adequate cooling. ---

It still crashes using one card. 9.1 is crap. [Previous page](https://forum.zcashcommunity.com/t/miner-claymores-zcash-miner/7114.md?page=68) [Next page](https://forum.zcashcommunity.com/t/miner-claymores-zcash-miner/7114.md?page=70)
