Newly installed Aorus Radeon RX 5700 XT causing PC to crash.

[sophistrysolipsist]

Hi, I just upgraded from Nvidia 950 to Aorus Radeon RX 5700 XT. Followed the guide, used DDU to wipe the nvidia drivers, swapped over the hardware, made sure its in the right slot and the power cables are properly inserted, restarted and installed the latest AMD Drivers(20.4.1).

It crashes and restarts the PC when I load into a game or try to benchmark it. Is it likely to be a driver issue or a hardware issue?

Power supply? are you using separate cables?

I went from a 6pin to 2 8 pins. Is this not correct? https://i.imgur.com/OvQgq9f.jpg Does each pin need a separate 8 pin directly from the power supply?

If you can, use two separate cables. Can help in some cases. Since the card seems like its having problems under any kind of load I'd suggest its an issue with the power supply. which power supply is it?

Ok. I'll have a look to see if it's got another one.

EVGA 600W 80 Plus Power Supply

600W was the recommended amount on the site.

Just had a look and it should be fine, and does come with 2 x 8pin cables, so try that mate.

It's a good power supply so the wattage shouldn't be the issue.

Ok thanks. This may be a silly question but where would I find the 2 8pin cables? As in should they be sticking out if the PSU? https://imgur.com/gallery/NzD7wnC

I bought it prebuilt from overclockers so I don't have the original psu box etc if it comes as an extra?

That cable in the last photo on your album. It's not a modular power supply so will be attached to the PSU.

Those are the 2 6±2 pin ones I had in originally.

Oh, must be an older model of the powersupply then. I'm afraid you'll need a power supply with two individual pci-e 8pin cables.

Ok thanks. So even though 600W was the recommended one, it needs 2 dedicated 8pin rather than 2 6+2 pins. Thanks. Is a PSU upgrade fairly simple to do? I don't have a lot of experience with upgrading myself. GPU seemed easy enough though.

Ok maybe some progress. I decided to go back to DDU and get rid of both amd and nvidia drivers, and made sure I was in safe mode this time. Restarted, installed AMD drivers making sure I selected specifically the ones for the 5700xt rather than let it automatically detect.

Loaded up a low end graphic game and it seemed to run fine. Went to load up Cod MW warzone and set it to the lowest graphic settings and it ran fine. Tried it again highest settings and it ran fine too.

Just tried the geekbench 5 benchmark and then it crashed again. So seems like it might be ok up until it needs to draw a lot of power.

 

[sophistrysolipsist]

uh huh. I edited some suggestions in my last post which you might find helpful at two different price points.

Seems like it's working fine for now for regular use so I'll keep monitoring it and keep those ideas in mind if it plays up again.

Thanks for everyone's help and suggestions, I really do appreciate it.

You've got to put the card under load to see if your issue is fixed. You say 'regular use' I infer from that internet etc, that's not going to stress your system.

I just tried a higher end game again and it crashes. It's fine when not under load. Must be the PSU as others have said.

Got in touch with customer service and they recommended a new PSU so I've ordered one. Seasonic Focus PX-850 850W 80+ Platinum Modular PSU.

I appreciate all the help.
