Nvidia and AMD GPU Latency tweaks and DPU Info (from KVRAudio)


Saw this on KVR and thought Id post it here as very interesting, useful and hopefully helpful.


To uninstall the current driver always use DDU and
set it to reboot in safe mode to remove the driver.

Updating nVidia drivers: Standard vs DCH drivers (I prefer the standard)

The Basic workflow is:

  • Disable Windows 10 Hibernate
  • Disable HPET
  • Use NVSlimmer to create a less bloated NVidia DRIVER
  • Use DDU to uninstall the current driver
  • Install the less bloated DRIVE trimmed by NVSlimmer
  • Adjust BOTH NVIDIA and Windows power settings
  • Make sure NVidia driver is using MSI

The [color=#8000BF]main [/color]NVIDIA FIX :tu:

[color=#BF0000]MSI[/color](Message Signaled-Based Interrupts) utility V3

Here MSI for the Realtek audio and NVIDIA GPU was not enabled, the Realtek LAN
was with set to HIGH priority. :o
Here it is not a server, it is now set to LOW :!:
I suspect for your DAW machines you may want to enable MSI for the GPU and
set it to LOW priority.

NVSlimmer, good to create a debloated installation driver

Stuff you may want to disable

Or just install the driver

For AMD GPU 5500/5600/5700 series, do not disable.
At least not with the current drivers…


[size=150][color=#8000FF]Some Windows 10 tweaks[/color][/size]

Set Windows Power Plan to “[color=#800000]Ultimate[/color]”.
(For AMD CPU it is different, more at AMD part bellow)

Disable Windows 10 Hibernate

Some good stuff:


[color=#BF0000][size=150]Tweaks for CPU AMD Ryzen 3000+[/size][/color]

Use latest Windows 10, not OLD builds…

[COLOR=“Red”]Disable HPET[/COLOR]
From Search, enter cmd and select Open as administrator.
Type the following commands to disable HPET
[COLOR=rgb(44, 130, 201)]bcdedit /deletevalue useplatformclock
bcdedit /set disabledynamictick yes[/COLOR]

Restart the PC for the changes to take place.

[color=#800000]After [/color]installing AMD Chipset Drivers

In the motherboard BIOS:

  • Spread Spectrum Control = [COLOR=“Red”]Disabled[/COLOR]
    [color=#8000BF]- PCIe = GEN3 (less bugs and more silent chipset fan)[/color]
  • Global C-state Control = Enabled
  • Power Supply Idle Control = Low Current Idle(if you have a new power supply unit)
  • CPPC = Enabled
  • CPPC Preferred Cores = Enabled
  • AMD Cool’n’Quiet = Enabled
  • PPC Adjustment = PState 0
  • ErP = Disabled
  • PBO = Disabled (initially I keep it disabled)

Now play with the machine and if all is OK can set the CPU CLOCK RATIO
to a fixed value to keep it locked at higher speed, lest say the
BLK = 100MHz with CPU CLOCK RATIO = 42 will get 4200MHz in all CPU cores.
Attention, [COLOR=“red”]max temperature[/COLOR] for the CPU is [COLOR=“red”]75° Celsius[/COLOR] or [COLOR=“red”]167 °Fahrenheit[/COLOR], NOT MORE! :-o

BTW, new DRAM Calculator for Ryzen v1.7.3 :clap:

AMD Ryzen - RAM OC Community


Quite old cards though aren’t they?

Yes, I didn’t actually pick up on that point Roo. I was aware of the alternative driver build minus the nvdia system panel and game tweaking interface, and this presented a few other areas I’d not seen before. More of a catalogue for ref as I’m shit at using browser ‘favourites’ .

Still valid tweakery but I don’t think I’ll be doing it on mine.

Just wanted to chime in for reference, as of being posted in October 2020 every GPU mentioned above should still be considered modern videocards which will likely continue to receive driver support for years to come.

Although vendors vary, typically don’t expect support after 5 years. Some will be less depending on the vendor. The only time this annoys me is if they force you to remove drivers for a particular product to make their new stuff work, without having support for that particular product.
