Topic: 2 GPUs out of 5 not detected (Read 151 times)
That was what I meant went I was originally telling you to test them. Maybe I was being a bit unclear and I could have communicated that better. When you are testing, I would always try to plug it directly into the board, rather than relying on the riser cables. The riser cables could be broke, or not seated properly. It adds an entirely new dimension to the issue that you can avoid through testing it directly. Since you got the one card working and you are bringing the last for repair, then does that mean that your problem is "solved"?
I saved 1 out of 2 GPUs that was buggy! How? I've unplugged all GPUs and try plugging one of the buggy GPUs directly in PCI-e x16 slot instead of risers, after a black screen of 10 minutes, Windows finally saw the GPU and displayed the image of Windows. After, I've replugged this GPU in the same riser and in the same PCI-e slot it was before and it's working well. So now I only have 1 faulty GPU which is still under warranty with MSI, I am brining it to canada's computer tomorrow to see if they can do something about it or else I will return it to MSI.
Yeah one of the first thing I tried is plugging only those not-detected GPUs one at a time but both are not getting recognized by Windows 10 Pro (64 bits). I've tried to put those GPUs into my other rig but my other rig doesn't detect them also. I am running Windows 10 Pro (64 bits), the OS only detects 3 GPUs out of 5.
When I was placing those GPUs on the motherboard the power supply was always turned off to avoid a shock. Something that makes me ask myself some questions is that those 2 GPUs when I am booting, their fans are running OK and all lights are on the GPUs and the LED light on the PCI-e risers are on also....
Thanks
If you tried them one at a time and windows 10 didn't recognize them does that mean that your bios recognized that card resp. you saw the boot screen when a monitor was plugged in? If you can't see the post messages or enter the bios, don't even bother with the cards, they are most likely gone and you only can replace them.
It sounds like the cards are not functioning properly, like I said before. If you tried plugging them into multiple systems that are able to run identical cards in the same slots, but these cards are unable to do anything then that would indicate that the cards are in need of repair. You can try running them on a new OS, but since you are in windows 10 are you able to see the GPUs under device manager? Since they are receiving power, and the fans are turning it is possible that the drivers are just not installed properly, but device manager should help us get a clearer picture of your situation.
Even turning off the PSU is not enough to prevent shocking the cards, even shocks that you are unable to physically feel, because of your threshold for "pain", are well above the amount necessary to kill computer components. Anti-Static bands, discharging your static electricity and making sure you have clean hands when you get inside your computer are a must. Were these cards working properly just a few days ago or have they always been giving you a tough time? What happened between when they were working and when they no longer were functioning as intended?

In device manager I see 3 of the 5 GPUs. I'm taking notes about discharging the static electricity, thanks for all the tips
. These cards were detected for couple of hours first but when I added more GPUs on the motherboard, some GPUs went off temporarily they came back but those 2 never came back even if their lights are all on and on the risers too (this tells me that the power are OK on it, so .. cannot be or low chances that they are defect right? I am thinking of migrating to a mining Linux OS like SMOS or HiveOS since Linux is well known to handle the ressources way better then Windows. I will also try to plug 1 of the buggy GPUs directly in the PCI-e x16 slot with all others GPU unplugged as soon as I get back home.Thanks for all your suggestions and if you think about anything else please don't hesitate to hit me back here !

Have you attempted to connect the GPUs one at a time to make sure they individually are functional? Are you able to place the 2 GPUs that are not functioning properly into another system to see if it is able to get them working? What OS are you running, and does the OS detect the GPUs at all?
It sounds like it would be the cards, maybe they died during a bad flash recently or got a good shock while you were placing them in without discharging your static electricity. If they are unable to work in a slot that other cards are working in, then it probably isn't the slot or the motherboard. The PSU should have enough juice.

Hi,
I am having an issue since couple of days about 2 GPUs that are not being detected by Windows 10. My other 3 GPUs are working fine. They are all GTX 1070. I've switched the 2 GPUs that are not being detected to the PCI-e risers of GPUs that are working fine but those 2 GPUs still didn't get detected. I've also changed the PCI settings in the BIOS for Gen 1 and Gen 2 but still the same issue. Both GPUs fans are running when booting and the LED light on the risers are also turned on green. I've uninstalled and reinstalled NVIDIA drivers, still same issue...
mining rig specs;
motherboard: MSI B250 PC Mate
GPUs: All GTX 1070
Power Supply: EVGA 1000 GQ, 80+ GOLD 1000W
Any suggestions are very appreciated,
Thanks.
