Hello, I have a 470 mining edition with a DVI video port. This GPU is recognized by the PC, sometimes it can work with load and be used without problems, but from one moment to the next it can stop giving video and stop being recognized by the PC. I tried changing the BIOS, changing the BIOS chip, reflow in the core and memories, it should be noted that at all times the GPU has all the voltage rails in perfect condition. It was tested on another PC while in mine it was not recognized and if it detected it, it no longer works correctly. My PC is an i5 with a 4th Asrock motherboard, the PC where...

Re: Rx580 8gb sapphire nitro+ turn off vcore randomly



I tried to reflow the gpu core only since I don't have stencils to do the reballin work, the same error persists in terms of fallen components, it doesn't seem like something is missing, I was taking a short break while ideas arose, the only thing What comes to mind is to perform another reflow with a little more temperature since the previous one I kept it at less than 220 degrees Celsius...

Re: Rx580 8gb sapphire nitro+ turn off vcore randomly

I tried changing the vcore driver and I didn't get any results, the gpu gives the image and loads the drivers but if I run a benchmark it turns off vcore, I removed the mosfets from the line that had a shorted one and I limited the electrical consumption as much as possible and the frequency of the core and memories through bios to try using it with only one active voltage line that is only 2 mosfets and it generates the same error it delivers video loads drivers but it does not support putting load on it, maybe it is the core...

Hello, this is my first post, English is not my native language but I hope you understand me. I recently got a 580 that didn't turn on the typical short mosfet, as I didn't know exactly which one was short, I unsoldered them until I got the bad one out, I was able to remove the short and identify the bad mosfet, the gpu gives video again! but it has a problem that completely turns off vcore at random times or if I try to put a load on the gpu vcore drops to 0 I don't have much idea why because I don't know much about sapphire, any advice on where I could start looking or what problem it could...
