I suspect there could be some voltage problem too.
- Asus card is plugged into PCIe 16x slot
- MSI card is plugged thru a 1x to 16x ribbon cable (with no extra power supply) this model https://www.amazon.es/Informatique-Riser-1-Puerto-16-x-suave-Reprise-alimentaci%C3%B3n-P6-Adaptada/dp/B071FNT4JK/ref=sr_1_8?rps=1&ie=UTF8&qid=1497961038&sr=8-8&keywords=riser
- My power supply is Mars Gaming 750W modular, which has a cable with 2 PCIe connectors, which are connected to both gpu.
Supposedly 16x provides 75W, and 1x just 25W, so I wonder if my connections would provide sufficient power
Topic: One of my RX 470 is causing my PC to crash and reboot.. (Read 292 times)
Managed to find 2x RX 470 the other day.
One is MSI RX 470 4GB, and the other Asus RX 470 Strix 4gb
The problems started when I flashed MSI RX 470 bios. I just did the typical straps with polaris (copy 1500 to next positions). After I flashed the BIOS I would get the error 43, device not working. After that I learned that it probably had to do with the drivers (Post Relive 16.2.1 version giving problems?)
but anyway, I switched back to backup bios, but the device problem wont disappear. Then it got worse and my PC would restart just after windows start, sometimes with strange colors, sometimes with a blue screen, but it seemed obvious its some issue with graphics driver. Soon I would not be able to use windows thru that card.
However, I had a second card, the Asus RX 470 Strix 4gb, so I plugged it in. I had to go out for the weekend so I just it left mining with no OC at all, and it would mine stable for 3 days at about 21 MH/S.
When I returned home, I received a riser from amazon so I could connect my other card (the MSI RX 470 that was having issues), it would be displayed in the device list with no exclamation marks. Also I tried to uninstall drivers and downgrade to a previous driver than the one was giving problems, but I dont think if it worked... (see the image below)
Seeing that it didnt have the device error any longer, I flashed both card's BIOS (just the straps) then set the GPU timings at 1100 / 1950 and undervolt at -75, and power limit +25, nothing else, followed instructions from Imineblocks video.
For a few moments it did seem like it would work and started hashing at 26 MH each card and about 780 MH decred. Then after about 1 minute, it crashed and my PC got rebooted. It would happen again every time. Its not temperature problem, its never going higher than 67º
Tried every combination. Removed OC from both cards. It would crash. Messed with different values in undervolting, overclocking or underclocking and overvolting, sometimes it would last longer than others but in the end it would always crash. I noticed that when switching to other application like chrome in a page with a lot of images, it would hang and reboot right at that moment.
After that, decided to unplug the MSI card, and its dual mining at 26 MHs with no issues.
However, Im going crazy trying to figure how to fix my other card................. Didnt almost sleep for 2 days quite literally.

(I thought I had installed a pre 16.2.1 patch, but in Trixx I can read crimson 16.11.5 beta, did I do something wrong?)
Anyway, any idea on what could be going wrong and how could be fixed?
Any help very appreciated because this is driving me nuts
