Windows: Line-Based vs. Message Signaled-Based Interrupts. MSI tool.

No you don't have to do that.

 

Hi
I managed to change sound blaster to MSI successfully.
Intel network controller and GPU RX 480 was on MSI by default
But SATA controller although has the reg key to MSISupported "1", in device manager has a possitive number "(PCI) 0x00000013 (19)". Also in "MessageSignaledInterruptProperties" key, except "MSISupported" value, there are some more values: "0x00000010" string name with no data, "MessageNumberLimit" DWord name with "0x00000008" data.
Any info on that matter?

 

Do not mess with SATA controller.
What chipset - Intel or AMD? What OS? What drivers for SATA?

 

AMD 990FX chipset - Windows 10 64bit CU

Drivers checked both microsoft and amd. None of them works in MSI mode

 

Just means it does not support MSI mode, which is common for some AMD chipsets.

 

I might have mentioned this somewhere back in this thread, but AMD patched out MSI from all 9-series AM3 BIOS due to an errata with the South Bridge.

You might have luck rolling back your BIOS to like the first few versions to bypass the errata "fix."

Use google to find the SB950 errata pdf, it states it in there.

 

OK.. I found this:

Improper Propagation of SATA Message Signaled Interrupts

Description

The SATA Message Signaled Interrupt (MSI) from higher port numbers may not properly propagate to port 0
before being sent to the driver.

Potential Effect on System

On a platform with SATA MSI enabled and activity occurring on SATA devices connected to three or more
ports, if the failing condition occurs, the driver will not receive the interrupt and the system will hang.

Suggested Workaround

Do not expose the MSI capability in the SATA controller. This change is
implemented in CIMx version 1.1.0.2.

Fix Planned

No

 

^ OP updated

 

Windows 7 or 8?

All "PCI Express Root Port".

You can change "NVIDIA GeForce GTX 1050" too but be aware that when you install new driver videocard is reverted back to legacy mode.

For a better safety check one device, apply and reboot Windows.

 

What about isa devices?

Friend what about ISa devices? isnt there a way to do the same for then and make em all msi mode instead of line based?

 

I would gladly, but they do not support MSI mode.
Also I suspect they are not real ISA devices but just emulated things.

 

Hummm got it thanks alot for your answer.

Thats because i bought an new f5-573g-59aj acer laptop that have an chronic problem about latency and switch drivers to msi mode made it ok on latencymon app.

I was wondering what else could i do to improve it since all drivers are already nice in msi mode hehehe

 

If notebook has HDD replace it with SSD. No other optimizations can be compared to that.
Then amount of RAM - 8GB at least.
Then fine tuning of performance plan hidden settings
Then amount of background programs and services.

Update: And good optimization would be to not play on notebook. I`ve been there and done that - ****ty experience. I will never again play on notebooks.

 

Is this supposed to be normal? i'm using an am4 motherboard asrock fatality ab350 and ryzen 5 1600 and I installed the drivers from the CD... but look at my ISRQ

have like 3 sata ahci drivers installed date 2006
I'm noticing that i have like input lag so bad :/ like games run a steady fps, but the input lag is terrible :/

 

You just should install proper AMD SATA and chipset drivers. Or just disable MSI for SATA.

I see that SATA and USB devices report MS drivers - hence I deduce that you did not install AMD chipset drivers (bundle usually has both SATA and USB drivers).

 

Latest chipset drivers for your system are here. Includes ahci.

No reason to not run MSI mode..

Only older platforms had issues with MSI mode.

 

Actually I installed through my Motherboard CD drivers. :/

 

It says Download not complete

I'm going to find the drivers there, because i use my motherboard CD drivers also double check in my manufacturer asrock web page for drivers, and are the same drivers, i will be looking in that web page that file

17.10rcp22-apr27.exe

 

Also i don't know why but this is my first time in long,long time by using AMD build, and with this Ryzen, i feel like even at high fps, my game is not smooth, like stuttering or something, i feel like when grabbing my mouse, i dont feel like I am actually in the game, i feel like with much Input lag, i'm pretty sure that is something with the BIOS ITSELF configurations, something with cpu settings, bridge or north etc, yesterday i disable simultaneous threading and single-core boost, and even the cynebenchmark, score went so down, the game dota2 did keep at 120 fps, and become more playable

Wish someone can make a good guide about what are all recommend settings in AM4 motherboas with chipset b350, in order to play more smooth... also people say, i guess thats your Windows 10 enterprise LOngterm, LTSB, and i say but, i was using this windows 10 on my old Intel machine, and everything was okay, but well :/ I know that i may be annoying by asking help, because i do my research too... but .

 

Guess you'll just have to select drivers manually..

Ryzen > B350 chipset > OS..

CD drivers are old so use website.
