MP 1,1-5,1 Videocard Problem ?!?

[frilli]

Hi everyone guys ..... sorry for the bad English !!!

I have a MacPro 5.1 with Xeon 5675, 48 GB Ram 1333 and Shaphire Radeon RX 580 4GB.

I noticed that on some games and some benchmark apps (Rise of the Tom Rider and Geekbench 5 for example) after a while the game has started, or the app, the Mac turns off suddenly ... I have to disconnect the power supply otherwise pressing the start button does not restart.

With Dirt3, Dirt4, Dirt Rally, Cinebench for example ... there are no problems !!!

What can it be ???

How is your RX 580 powered ?
============================================
EDIT 1 : I just noticed that you have a 4 gb RX 580 4gb. I'm not sure if that model has an 8 pin socket. too busy now to check.

EDIT 2 : Just checked. YES you do need the cable if your RX 580 is this model

============================================
It should be powered ( if an 8gb model ) by TWO Mini 6 pins ( on the cMP motherboard) to ONE 8 pin

yep sounds like you have not corectly powered the card, you need both 6 pins to go to the 8 pin on the gpu

Why is it that new members simply dont get it that EVERY video ( GPU ) card has different power requirements ? and that as MacUsers we need to include in first posts a general overview of their cmP current setuo.

EDITED

it is not a mac thing, it's fairly common with windows boxes to, it may also be something like a bad OC/undervolt/mining bios/power cable or wall socket

But yep 99% it’s power cables then mining bios then bad OC/undervolt

I still find it funny when I see posts on steam 'this game uses too much CPU my computer crashes' that ends with 'I OC'ed to 5GHZ on the stock intel cooler and my CPU was a ball of flame'

there have been a few DOA gpu's to that got RMA'ed

Thanks to all, problem solved, it was the cable that fed the video card.

Is it possible that now it takes longer before the "gong" arrives ??
