Modded NVMe Drivers for Intel(R) Optane Controllers

[Fernando]

@mattlach

If I have a running Windows 11 install, which already has the Microsoft NVMe drivers installed, are there any tricks to installing this driver?

No. Look >here<.

@mattlach

Do I need to install the cert?

Before you are going to install any mod+signed drivers, you should install the related Certificate. >Here< is a guide how to do it.

I tried just going to the Device Manager in an admin account, browsing to the Optane drive, selecting it, choosing “update driver”…

You cannot update or replace the driver for a device, which is listed within the “Disks” section of the Device Manager. If you want to replace Microsoft’s in-box NVMe driver, you should expand the “Storage Controllers” section and update the driver for the listed NVMe Controller.

Fernando, these drivers work great. Performance gains are hit/miss. For reference, this is a X670E based system with a 9800X3D and a 1.6TB P5800X.

Stock driver.

Modded 5.3.0.1010 driver

Seems like 4KQ32T1 locks to one core and wont spread the load in both drivers.

One thing to note is that the modded driver does not fully support direct storage. See below

Any other drivers to try?
