Hi, I hope someone can give me some help with this issue.
In the last 3 months I have built 2 near identical PC's - same case, RAM, Processor, motherboard etc. Both PC's have Radeon R9 270x cards fitted, although in this case by different manufacturers owing to stock issues at my supplier. They should however produce very similar results.
The older of the two machines performs very much as expected. The newer machine, however, was/is suffering with a 'display driver has stopped responding and has recovered error'. I installed and ran 3dmark 11 on both PC's. The result on the older pc was, again, much as expected. The newer machine however was running at much lower frame rates on the benchmarks, and the score was much lower than the other identical machine. I did a thorough uninstall of the catalyst control centre and the display drivers, rebooted, reinstalled, rebooted then ran 3d mark again. The result was still much lower than it should have been.
At this point I was thinking I had a faulty card. To test this, I removed the graphics cards from both machines, and swapped them over. The scores remained in the same ballpark on each machine. i.e. the newer machine performed poorly with both graphics cards, and the older machine performed as expected with both graphics cards. This seemed to eliminate the cause being a faulty graphics card.
I updated the BIOS to the latest version, and the problem still persisted. However, I stumbled onto something -
when I boot the computer, and go into the BIOS without changing anything, then boot into windows, the graphics performance improves to where it should be. If I perform a normal boot into windows the performance is poor. I'm now trying to understand what is causing this, so that I can cure it without having to boot via the BIOS. This is what I have tried so far, with no success:
1. Disabled fast boot
2. Changed the POST delay from 3 seconds to 6 seconds.
3.Enabled Interrupt 19 capture in the boot settings
4. Changed the boot priority for PCI-E expansion devices to uefi driver first.
No success. The only thing that works is to boot, go into BIOS, exit without saving changes, and boot into windows. I would be grateful for any help with this frustrating issue.
