i need your help, i assembled system and bought MAG Z490 TOMAHAWK. I bought m2 980 1 tb 4.0 ssd as SSD. It shows as gen 4.0 compatible on the msi site. The bios sees the ssd but not in the windows installation process. what is the problem? I did the latest bios update. https://www.msi.com/Motherboard/support/MAG-Z490-TOMAHAWK.html#support-hdd PCI-E M.2 Samsung 980 PRO - MZ-V8P1T0BW 2280 Gen4 1TB bios version: Version 7C80v19 Release Date 2021-07-06

First of all, is your BIOS in UEFI mode? Can you make a proper screenshot of the whole BIOS page by pressing F12 and saving the picture to a FAT32 USB stick?

Secondly, your CPU can't do PCIe 4.0, only 11th gen CPUs (for example 11700K) have PCIe 4.0 lanes from the CPU. Therefore your 980 PRO is limited to PCIe 3.0 x4 speed. This of course makes the 980 PRO a bit too expensive, a 970 EVO PLUS would've gotten you the same speed on PCIe 3.0 x4. Anyway.

Thirdly, make sure to use the newest Win10 installation media using the latest Media Creation Tool. In the Media Creation Tool, select "Create installation media (USB Flash drive)", then a USB stick will be prepared. Then you have to boot from the stick (press F11 during boot for the boot menu, select the stick there) and install. If you use an outdated installation media, things like this can happen too.

I downloaded the latest windows 10 from microsoft site. I did the usb install. it saw the storage unit while installing windows, but there is a problem windows 10 is installing. After the computer resets, the bios screen comes up and the windows installation continuation screen does not come at all. but as you said, I regret seeing it on the msi site as 4.0. I wish they would give a warning or notification. I bought it because it was suitable there and I regretted it very much.

I have the Z590 Tomahawk using a NVMe PCI 4 in slot 1 and a good NVMe PCI 3 in slot 2 and the speed difference is not notable in most cases. The only real notable is the huge write cache in the Samsung 4 unit.
Maybe the Samsung unit could run in slot 2.

Did you boot from the Win10 installation USB stick by pressing F11 during POST to bring up the boot menu?

There is something I don't understand. It supports 3.0 and runs at 4.0 speed. Why doesn't the system run when I insert a 4.0 m2 ssd?

Is your BIOS in UEFI mode? It would help if you could make that proper screenshot. I wouldn't give up so easily, it might be a matter of one BIOS setting.

Is your BIOS in UEFI mode? I have checked the "yes" bios settings many times. I will take pictures during the day. Can you explain that mag z490 tomahawk model 10700k intel processor is available. Samsung 4.0 980 pro m2 6900/5000 could it be incompatibility problem?

You could try to put the 980 PRO into the second M.2 slot, as was suggested. For the performance, this would make no difference, as both slots are limited to PCIe 3.0 x4 with your CPU. But it could make a difference for your problem.

There is no incompatibility, since PCIe 4.0 SSDs work fine in PCIe 3.0 mode as well. Also, this 980 PRO SSD is quite popular (i have one myself) and there would be lots of people complaining if it was incompatible on Z490 with a 10th gen CPU. So i think the problem is something else, not incompatibility.

I downloaded windows 10 from microsoft site and booted usb. When it completes the installation and resets, the computer automatically opens the bios.

On screenshot 3, the "USB hard disk" boot entry has the top priority. Did you change that yourself? This is something that you usually avoid by using F11 for the boot menu. You don't touch the boot order at all, it will be set correctly once Win10 has finished installing.

Try the following: Clear CMOS by shorting two pins with a screwdriver (described in the manual). Without doing much in the BIOS, boot from the USB stick via F11 boot menu and install Win10. See if it boots Windows afterwards.

I will do what you said and get back to you.
