Rx 480 unstable.

[MaXxBoulton]

Friend at college as a rx470 that's unstable on the new drivers unless he under clocks the card.

The card was fine but now when he rolls drivers back it's also unstable.

Dead card?

Yea could be, the drivers could be a coincidence.

When you say unstable, what exactly is happening? Screen freezing then going blank when gaming?

Under any 3d load the screen locks up a random solid colour.

Stock clocks are 1221 core, 1750 memory
If he drops clocks to 1100 core, 1600 memory then it runs but will flicker a little

He as a freesync monitor and says it's the same with it on and off

Have you tried leaving the clocks at stock and undervolting?

Are you able to see what the temperature is at when gaming?

Beginning to sound like a memory failure :/

It crashes as soon and the game loads up,
It works ok in windows and you can watch films and so on but under s3 load it crashes on loading.

Is there any program's that could test this with different gpu ram loads

What make/age PSU? Could be coincidence as mentioned above, but possibly a failing PSU?

The RX480 (and presumably 470) at times pulled more power than they should through the PCI-E slot.

Might even be worth trying in another PCI-E slot if the board has another (in case it had caused some kind of long term damage)?

he just go back to me, he as a green label corsair CX430 i assume old. the new gray label as been out 2year?

on a side note he thinks the gpu was used for mining before he had it

 

[Armageus]

Cx430 is probably borderline for an rx470/480 anyway, age wouldn't help though

TBF when he said CX430 i thought this touch and go.

the thing that gets me is it was working until he clicked update, he as had the card 3 months

Every time I've had this problem with GPUs (having to underclock to make it stable) it's been a hardware fault.

It can be a weird one and not to it on every game though.

went round to his house to test a few things for him before buying a new GPU and i noticed this when running prime95, could this be the problem or is drop under load normal?

12v rail has a +- 5% tolerance, so between 11.4v and 12.6v is within spec.

If you've got access to another PSU though, i'd give that a go before buying a new gpu

Thank for the info, I will pull mine out and take it round tomorrow,
