After a very long time I managed to get into this forum. Every time I login, I am automatically logged out. It’s understood that this is server-side caching issue but with no one looking into it, I have actually asked Mods to delete my account, so these could possibly be my last posts on this forum.
I have assembled a number of desktop PCs so far and while I look into QVL, I could never strictly go by that list either because the parts were very expensive or the parts were not available in India. They were never meant to be sold in this region. A part not listed on Storage QVL by default does not make it incompatible when a standard is in place. Otherwise I believe a disclaimer needs to be put in place by the manufacturer on their specs and support sections.
SATA, M.2 form factor & PCIe NVMe is a standard and all interfaces need to make themselves compatible with the standard. This appears to be some sort of design error on part of ASRock. Moreover it’s also fishy that they have not linked the PDF from their affected board’s support section. It’s a lone floating document on their server without any reference or links from existing pages. Hence easy to be missed by search engines.
There would be no reason for OP to doubt that SN5100 or SN850x would be incompatible with ASRock B450 board. But unfortunately, we have hit a rare event of incompatibility. That’s the main reason I do not give very specific buying recommendation by the make/model number. Giving a very specific recommendation requires lot of homework!
As a general comment, a common question users have in mind when buying a PCIe NVMe adapter card is - will it make the system bootable. Unfortunately, there’s no definitive answer. It depends upon how BIOS sees the PCIe card. If BIOS supports it, it will be bootable. Try checking with ASRock support if they have any meaningful response on such a query.
i have asked them the same and have sent links of 2 verilux and 1 ugreen cards to ask if it is compatible. both these companies have said that it will be able to work though i forgot to ask if it will boot the system which i have asked now. thanks.
EDIT:
Ugreen says it will be able to boot the system as per the given specification.
Verilux does not say anything in this regard.
ASRock says "The adapter you listed in your email should be able to work on this motherboard. Please check the specs of this motherboard to prevent the possibility of PCIE lanes conflict."
so i will be placing an order for the ugreen one and then try to insatall windows 11 on it.
