Which Main-Board are you using. It could be trying to utilize tech that has now been abandoned . Its sad but if your buying into a new 2016-2017 GPU your going to have to replace almost all the hardware.
Simple board replacement should cover it. Unless you just got one, but you didnt list what ( MoBo ) your using.
ASUS PBZ77-V LE PLUS
But... the timeline of this motherboard (~early 2013) is rather close to R9 280 release date (October 2013). It seems illogically to me since I'm experiencing exactly the same issues with an old 280X card.
Just to be clear we are talking about the
Power Color Red Devil RX 480 8gb DX12 Full unlocked with full VR support,
something windows-7 will never utilize or be able to use, on a MoBo that predates standards of todays A-Link A-series APU's which this is Intel and Intel hadnt come up with a name but still drivers changed regardless.
My point being, and i guessing you know the GPU you installing is a monster and was built for todays leading OS and sysems right ?
Win-7 never added SSD support with almost zero compatibility. You would not need this GPU for windows-7 or would recommend trying it ( imo)
Not that im bailing on any help i like to share, there just no helping a dead OS , your problem might not even be hardware in that case.
The p8z77-v le plus was built and standarized for 8.1, meaning its not a Win8 hardware, 8.1 is different so was the hardware made for it, thats offtopic but dead on
Ask me, your best shot is Win10, something that will actually support this kind of hardware, including the board.
If you tried Win10 and it hung or crashed,i would guess there is conflict inside the board like every other win8.1 hardware that is now known to be the worst hardware for compatibility .
PCIe support your going to need and is needed for the Red-Devil is found in windows10. This is actually the reason i thought i could help
You listed Windows-7 Reinstalled as first item but i didn't see it until now, when i double checked to see if i overlooked that info.
Not trying to be blunt or something, if it was a reference 480RX that actual drivers for windows7 could be known to work could be gotten i would say there would be a chance
This i know, ive owned in the past off branded company cards like Power Color before , they ship with a driver and thats it. Once that driver dosent work anymore its either done or work around time
Your going to have better luck on the Power Color Forum for this one, if they have one for support.
Grab your driver HERE : PowerColor Official Website - Graphics, Cases, Power Supply
and call these people on phone, ask about windows7 support, if this forum dont work out.
Link to there FAQs Q/A on that page to
They all look like problems and its 37 pages long, it might be worth taking a look at, your problem is probably listed.
You have a nice board and a nice card.
Thanks for this text.
I rolled back from 16.12.2 to 16.7.2 but got no effect about the issue.
Still sure I am on the proper forum. Sapphire and Power Color are not the same organization as far as I know. But their products doing the same things.
I'll get Win 10 installed in 2 days, going to let you know the changes.
Should be good to go on windows-10
Im about to drop a GTX-1070 onto a machine passed over to me, but it may be suffering from some current OS build Intel problems. There is that fact to consider when looking back into it.
No error reports in windows reliability history (not event viewer) ?
Got any pics/links to specs of psu ?
I have a z77 board/3570k, it's had a 6970/7970/now 390 on win7/8/8.1, now win10, with no major problems.
Check for mobo bios/driver/intel cpu/other hardware updates.
Some of the factory overclocked cards have some stability problems. I suggest running the cards at stock clock speeds and perhaps giving the card extra power with a tool like MSI Afterburner
Unfortunately it's not easy to fix problems like this, the best solution is to reprogram the video card BIOS to reset the card to stock speeds.
Another raft of problems is due to flakey coolers. Sometimes the thermal material is not applied properly.
Well, guys, I've got a decision. Finally...
That was nothing about windows or anything else. The answer is BIOS version.
Quote from ASUStek site BIOS support chapter:
P8Z77-V LE PLUS
BIOS version 0905
1. Enhance compatibility with some PCIE device. <<<<<<----- THIS
2.Revise help string in BIOS.
3.Support new CPUs.
Thank you for your time.
I hope my case will help someone in a future.
