MessageNumberLimit MSI

[BTRY B 529th FA BN]

I have a device, my onboard Realtek Nic, that is automatically set to MSI mode. I recently checked it's registry entry and I see there is a MessageNumberLimit and it's value is set to hexidecimal 1. PCI 2.2 supports entries of 1,2,4,8, or 16. I don't know what PCI revision is on my board. There is only 1 PCI slot and 4 PCIe slots on my E760 A1 EVGA board. But I set the MessageNumberLimit to 16 and upon reboot it BSOD. That's not the interesting part. When I rebooted again after windows said it couldn't fix the issue it booted into Windows normally and the registry entry is still what I left it, at 16. I'm kinda stumped as to what the BSOD'd reboot followed by a perfectly normal reboot means 😕

Is the message limit operating at 16 or did it default back to something without changing the registry entry?

Is there some reason that you are mucking about with low-level IRQ / APIC / bus device-driver config stuff? Is there some compatibility problem that you are trying to solve? Because if you are looking to eek out more performance, you're probably looking in the wrong place.

I wanna know why it BSOD'd the first reboot after changing the limit to 16 then all rebooting after that is fine

And what about performance?

I don't mean to be a necroposter, but I am looking to get more performance. Can you please list topics I should be looking for to increase performance(motion to photon latency and FPS in video games, DPC latency and probably something I don't know about yet but you do).
