Did you connect up the power to the card? Have you rebooted since installing the driver?
Assuming you did both it might be a hardware problem :-/ Or it might have a modified bios on the card for mining which the normal driver doesn't like, you could try and flash it or you could just return it :(
Hi I have the power connected it actually has an 8 pin socket and I plugged in the 8 pin power supply plug , the graphics card is running as all the lights are on and the fans are going. The monitor is connected to the graphics card hdmi port and is working although the resolution has changed. Also the graphics card is plugged onto the board fully, I have checked.
I downloaded that uninstaller but when I click run nothing happens it just says extracting to a file but that file address doesn't seem to exist on my pc.
thanks for your help, if it was you it would probably be easy to get it going but I am wary of downloading strange stuff onto my pc that I don't understand so I think this thing is going back. Thought it would just work, didn't realise there was so much involved. i wrongly assumed the crowd selling it would have checked it was working ok without the need for flashing etc.
CEX do test graphics cards as they work on a universal platform.
The reason they don't test RAM and CPU's etc is that they'd need multiple types of boards/socket types which isn't that feasible. It's also the reason why stuff gets incorrectly labelled very often in there, eg EEC Ram sold as normal Ram, etc.
Graphics cards though can be tested on a single PC setup for that purpose, they run them through Furmark or 3DMark or something of that kind.
They're still generally fairly clueless though. Had a guy in CEX tell me a card I traded in "failed due to overheating" because it reached 80c....a perfectly normal operating temp for tons of cards.
Anyway, they should have tested that RX470 and found it to be working OK, but might have slipped through the cracks somehow.
The DDU file comes in a 7zip self-extracting archive.
When you click it, it should ask "Extract to:" Click Extract and it should create a new folder called "DDU v18.0.5.9". That's where the actual "Display Driver Uninstaller" tool resides.
The fact you're getting a signal is good! I suspect it's simply a driver conflict from the fact your machine used to have a GTX 770 years ago & you were running with Intel drivers for ages.
