Hi guys,
I was lucky enough to snag myself a 9070XT from OCuk last week. Unfortunately I've had a number of issues with it. Firstly the bracket was oddly aligned and when I screwed it in firmly to my case it lifted the card enough it didn't make contact with the PCIe lane.. not visible with naked eye unfortunately so took a while to diagnose. I got around it by using the anti-sag bracket to lever the card in place as it went over the top of the same screw holes, it hasn't budged an inch since and I've been unplugging/re-plugging screens constantly because of my main problem..
Main issue is I get random black screening when I reboot my PC, it's like the PC is failing to post. It's a white line (like a MS-DOS style cursor) on a black screen. If I button the PC it goes straight off, and if I turn it straight on it does it again but this time after a few seconds proceeds to BIOS splash screen and Windows boots up normally. Once I'm in Windows it's solid. No driver issues, great performance, no crashes. Used it since Thursday like this and it's been great apart from when I need to reboot for a driver or Windows update.
I've updated my BIOS and disabled auto-GPU detection for onboard iGPU (although I don't have one on my 5900x) and also forced the PCIe and Chipset into Gen4 from auto after I read about issues with Auto defaulting to Gen 5 which I don't have. List of specs below. Any advice appreciated, I really, REALLY don't want to return the card but if I can't have a reliable boot.. then guess there's no choice for me.
Specs below:
- Manufacturer: Sapphire
- GPU: Sapphire Nitro + Radeon RX 9070 XT Gaming OC 16GB GDDR6 PCI-Express Graphics Card
- OS: Windows 11 24H2
- The other specs of your machine:
- AMD Ryzen 9 5900X 12-Core Processor @ 3.70GHz
- MSI MPG X570 GAMING PLUS (Latest BIOS applied)
- Kingston FURY Beast 32GB (2 x 16GB) 3600MHz DDR4 RAM
- NZXT C850 850 Watt 80+ Gold PSU
- 4 x Monitors connected.
- 2 x LG Ultragear+ 32inch @ 4k/240hz
- 2 x LG 24BA650 24inch @ 1080p/100hz
Haven’t read all the thread in detail, but, have you simply reseated the GPU? Have heard of similar issues with the 9070XT that reseating fixed.
Have you also/or reset the BIOS to defaults and/or cleared the CMOS by jumper or removing the battery?
If it still doesn’t work, I’d update the BIOS if you haven’t already done so.
I’ve never personally heard of a GPU that is working perfectly but causing a specific issue like that. Similar to what Andy had with his and it turned out being a power issue.
This sounds more BIOS/settings related to me.
