280x Dual-x

Nolars

Well lads,

Recently got a Sapphire 280x and went to set her up yesterday and nothing, the fans and lights and all work grand but gpu-z doesn't recognise it.

Running an amazon 450w bronze psu. Updated the asrock pro3 to latest bios.

Seems to be a good few posts where someone ugrades to a new gpu from an old one(7870 in my case) and it wont boot to monitor like this - http://www.tomshardware.co.uk/answers/id-2218749/detect-sapphire-toxic-280x.html

http://www.tomshardware.co.uk/answers/id-1943123/computer-detect-video-card-anymore.html seems to be loads of the same problem but no solution? would it be the psu

Any ideas?

You did install the drivers and the AMD gaming Evolved app?

This. It might sound odd, but the Drivers included with the Driver CD are probably as far back as Catalyst 13, so just check you're running the 15.7 (I think?) driver.

He can't get even the POST to display, and no it's not a card fault.

Does that model have a uefi bios switch, i've had a similar problem with a 280x toxic and that solved it.

Ya I've tried it both ways neither works. Also the last update for the mobo was 2013 for the b75 as rock.

Did u turn it on and it worked for you or the other way around.

Nolars, go into your BIOS and have a look for for the PCI-E settings. If this is switched to Auto try change it to Gen 2 and see if she works then.

PCI Express based PC is required with one X16 lane graphics slot available on the motherboard.
4096MBMinimum of system memory.
Installation software requires CD-ROM drive.
DVD playback requires DVD drive.
Blu-ray / HD DVD playback requires Blu-ray / HD DVD drive.
750 Watt Power Supply is required.
1000WattPower Supply is recommended for CrossFireX System.
2x150 Watt 8-pin PCI Express power connector is required.
4x150 Watt 8-pin PCI Express power connector is required for CrossFireX system.

PSU recomendations according to newegg.
According to this the card wants 300W

A 450W PSU does seem a bit low especially for such a power hungry card. What CPU / Motherboard are you using and how many HDD / Disk drives are in the PC?

I don't think this is the issue happening but it may be something that happens down the road if the system is really stressed

This might sound stupid, but you do have two 8 pin power connectors plugged into the card?
Considering you can update the Bios I feel like a fool asking.

Ya I realise its fairly low tbh. And no its only a 6 + 8 pin PSU. I'm hoping thats the issue I might aswell get a new PSU now anyhow was looking for an excuse. Shdnt it still be recognised by the PC anyhow if its powered on with lights and fans spinning ? I dunno

I'd still reckon that's the issue Nolars, not that I had thought of it until you mentioned it.

You could just pick up an adaptor for it
