I have a X570 Gigabyte Aorus and 2xNVMe Gen4x4 drives.
I get 10GB/sec reads (expected) but writes are capped at 2GB/sec.
Each drive on it's own (outside of RAID) performs at about 5GB/sec read/write.
Do you know what might be wrong? I see others as well reporting bad performance on RAID 0.
Full system specs follow. All of this is brand new out of the box yesterday.
In the BIOS under "Boot", CSM is Disabled
BIOS "Storage Configuration" has SATA controllers in RAID mode, but I don't have any SATA devices. The "Storage Device(s) List" there is blank.
NVMe RAID mode is Enabled under "Advanced\AMD PBS"
Under "Advanced\AMD CBS" everything is set to defaults, mostly "Auto". IOMMU is Disabled.
In the Advanced\RAIDXpert2 Configuration Utility:
Viewing the Associated Physical Disks, it shows
If I dig down to look at the physical disk properties they look correct, Used Space is the full 1.0 TB, they are both associated with the array and not hot spares.
So that's the hardware and BIOS config...
I save changes & exit from the BIOS, and boot Windows from USB. I created this USB yesterday using the Microsoft MediaCreationTool20H2.exe. My license key is for Windows 10 Professional.
I have also installed the AMD RAID drivers referred to above on a second USB.
Windows comes up, I start the install. "Setup is starting".
I enter the Windows registration key, accept license terms, and choose "Custom: Install Windows only", not Upgrade.
It asks: Where do you want to install Windows?
The list below shows:
So Windows sees the raw disks, not the RAID. This is expected since I haven't loaded the drivers yet.
I click "Load Driver". It says "No signed device drivers were found ..."
I click Browse and go to the USB drive with the AMD RAID drivers.
This is where the first problem with the instructions shows up: Which drivers? NVMe_CC or NVMNe_
, down to WIN10/x64/NVMe_CC/rcbottom and click OK.
This is the second minor problem with the instructions: Windows now says "Select the driver to install" and shows TWO IDENTICAL LINES:
AMD-RAID Bottom Device (D:\WIN10\x64\NVMe_CC\rcbottom\rcbottom.inf")
However, from reading AMD NVMe/SATA RAID Quick Start Guide for Windows® Operating Systems I've seen that this can happen when the system has multiple controllers, so no problem - I choose the first one.
Now I'm back to "Where do you want to install Windows?" but there are no drives shown. Progress!
Again I click Install driver, this time browse to NVMe_CC\rcraid
and install the AMD-RAID Controller [storport] (D:Win10\x64\NVMe_CC\rcraid\rcraid.inf)
Now I'm back at "Where do you want to install Windows?" and it shows
Drive 0 Unallocated Space 1862.0 GB / Free space 1862.0 GB
Woohoo! It's working. But I still haven't installed rccfg, so I browse down to and install
AMD-RAID Config Device (D:WIN10\x64\NVMe_CC\rccfg\rccfg.inf")
With all three drivers installed I'm back at "Where do you want to install Windows?" and it still shows the same Drive 0 Unallocated 1862.0 GB as before.
I select that and hit Next.
Windows now begins the installation.
This depends on which processor you are using. Please let me know and i will point to the correct package.
As an aside we are updating the help documentation to improve this so it will be much clearer than before which package you need.
Good day, there is :
Crosshair viii formula (latest beta BIOS) / 5900x / 2x Sabrent nvme 4.0
during installation windows i try NVMe_CC and NVMe_DID, but two disks are still displayed....
Ryzen 5000 series processors need to use the nVME DD folder.
What Raid are you trying to setup? If you followed my instructions i posted earlier in this thread, it should work.
I try raid 0. In bios I'm creating raid, and at first glance everything is fine (I can add screenshots from the BIOS). Then I made a bootable USB flash drive and added drivers there. During installation, I add 3 drivers sequentially from the DD folder, they are installed, but still two nvme disks are displayed.
There is one more strange moment (maybe it is connected). I connected another one simple SATA HDD (WD 2tb) from my old computer, but neither BIOS nor Windows sees it during installation
Did you enable nVME Raid in the BIOS?
Are you loading the three drivers in the correct order?
It sounds like you may have missed a step.
Strange thing. tried again from the beginning. In the BIOS, I left SATA in AHCI mode (before that stood in raid), and nvme as raid. I got to the driver installation and this time I could not install anything from the nvme_did folder, the list was empty, like "incompatible with my equipment". But from the nvme_cc folder (for a different processor) - success, and one disk appeared! While everything seems to be established and working, I observe.
