I recently moved from an MSI Godlike x670e board to the Crosshair x670e extreme due to reliability issues. I'm using 4x nvme drives (2 on the board and 2 in the special DIMM add-on.
Each pair is in a RAID 0. For some reason, any 2 nvme drives that are directly connected under the pcie slots are not being recognized as being in a RAID 0. I can't seem to find configuration or drivers that would associate them as such.
Currently I have an optane drive in the first x16 slot and my nvidia 4090 in the second x16 slot, then theses 4 nvme drives (2 sabrent 8TB drives and 2 2TB samsung drives) each in their own RAID 0.
Any ideas? With most boards, I can simply swap the drives and the RAID arrays are there. I've been carrying these RAID arrays from my old x570 platform.
Could you please confirm if, according to your description, the two NVMe drives connected using the "special DIMM add-on" can be properly recognized in RAID 0 within the system, while the other two directly installed on the motherboard cannot?
Does this issue occur in the BIOS or within the operating system?
Please help to confirm the question below for us to better understand.
- are the two NVMe drives directly installed on the motherboard, placed in the m.2_1 and m.2_2 slots?
- what is the specific connection method for the "special DIMM add-on"?
Could you provide detailed information or photos?
- when it is mentioned, "each in their own RAID 0," could you clarify its meaning?
RAID 0 typically requires a minimum of two drives to be connected
- the current BIOS version and the images of the setting in BIOS, or whether it is the default
- what is the RAID configuration setting in the BIOS?
Please refer to the BIOS manual under the ROG CROSSHAIR X670E EXTREME's official website > support page > Manual & Document section for further information on RAID-related settings if needed.
- the brand and model name of the CPU, GPU, SSD/HDD, RAM, and PSU currently installed
- the OS version and OS build
Thanks for the reply!
1) Yes that's correct. The add-in card has no trouble recognizing my RAID 0 arrays. But the two slots on the motherboard cannot.
2) In the BIOS, only one nvme from slots M_1 and M_2. When I put the config in RAID mode, it doesn't seem to help.
3) Yes they are installed directly into those slots
4) The add-on is the ROG Gen-Z.2 slot. It is the successor to the ROG DIMM.2 slot that houses additional m.2 drives. It's included with the motherboard as an accessory. https://rog.asus.com/motherboards/rog-crosshair/rog-crosshair-x670e-extreme-model/
5) In terms of 'each in their own RAID 0', I mean that I have two samsung 990 Pro 2TB in a RAID 0 and two Sabrent Q Rocket 8TB m.2 drives in a RAID 0 for a total of 4 drives in two different array groups.
7) I could not find RAID configuration settings in the BIOS at all for those drives. Somehow the RAIDs have always worked after moving them from one board to the next.
😎 Ryzen 7800x3d, nvidia founders 4090, GSKILL 32GBx2 6000mhz memory, Corsair 1600i PSU. Hard drives are: 2x Sabrent Q 8TB nvme drives, 2x Samsung 990 Pro 2TB nvme drives, 1x Intel Optane 905p 1.5TB PCI-e SSD (primary boot drives) and one 22TB Western Digital Datacenter drive.
9) I have the 4090 GPU in slot 2 however, because the EK waterblock won't fit in slot one. The intel 905p is in pci-e slot one.
Regarding confirming the RAID settings in the BIOS, have you referred to page 44 and page 47 of the BIOS manual for the configuration pathway?
We recommend that you not only check if NVMe RAID Mode is set to [Enable] and test with setting to [PCIE RAID Mode] in PCIEX16 Bandwidth Bifurcation Configuration, but also verify if the relevant driver versions are up-to-date within the OS.
Meanwhile, please try cross-testing both sets, one installed directly in the M.2 interface and the other connected through the ROG GEN-Z.2, or test each set separately under different BIOS configurations, if needed.
If the problem persists, kindly provide the images detected in the BIOS during testing, the OS version, the OS build, and the relevant driver version.
