Surface 8 Pro - new SSD - compatibility with PCIe 4

The update hasn't made any difference . My ssd still locked up then restarts, presume this is down to the increase power comsumption.

Hello,

I tried your trick with WD SN740 1 Tb. It works perfectly if the surface is plugged in AC. I cheked the ssd with the official WD Dashboard and everything is ok. Run very smart and fast.

But... on DC, it freeze after few seconds.

Applied all the trick of Lalaneta's post but works only on AC power. I've checked that the DC Power Settings in Registry is set to 0, like AC Power settigns, but doesn't solve the problem.

I Tried to set HCPI to HCPI+DIM instead of Active, but same problem.

Anyone have an idea ?

Thanks

Finally, I found how to solve the problem with the trick posted by Getter Robot in the 31th december 2022:

1. Enable "Link State Power Management" option in Power Options.

2. Choose "Off" for "Link State Power Management".
3. Reboot.

And now everythings are ok with the WD SN740 1Tb.

Did same thing, it works usinbg WD SN740 1Tb, but I'm facing issues when SP8 sleeps and try to wake... it reboots =(

let's make a appeal to Microsoft to solve this problem, it makes no sense to wait passively, automatic switching of the screen refresh rate from 120 to 60 did not appear after a year
