GA-Z170-HD3P & MZ-V5P256BW problem

[gremium]

Hi, Sorry for my poor english. I have GA-Z170-HD3P & Samsung MZ-V5P256BW as system disk (WIN 10 PRO 64). After BIOS update from v. F4 to F5 there is no (disappeared menu "NVMe Configuration" and drive 950 works slowly, reading is at about 30% of initial performance. Computer previously worked great and disk worked with performance declared by Samsung. I have no idea what to do :-(

The first thing to try is accessing the BIOS, select "Load Optimized Defaults" and boot to the OS. Determine if that resolves the problem.
Check your BIOS settings one-by-one and see if you can spot a setting that needs to be changed.
Reinstall the Samsung 950. Check to see if there are any firmware updates.
If problem still unresolved contact Gigabyte and see if they can be of any help.

Hi. All firmware is updated. I tried "Load Optimized Defaults", etc, and different other configurations (I build computers for about 10 years). Reinstalling is impossible, PC must have to work. Gigabyte can't help - they don't answer.

Have you looked into the possibility of reverting the BIOS for this Gigabyte board? Can't recall if the Gigabyte saves the previous BIOS when a new upgrade is installed.

I tried to downgrade bios to older v. F4, but with no improvement.

I'll assume you've checked the health of the SSD with Samsung Magician, but in the event you haven't, do so.
I suppose your only reasonable alternative at this point is to contact Samsung to invoke an RMA.
