I just bought adata memory and an ASUS Z690 ROG Maximus Apex board. The memory is ADATA XPG Lancer 6000mhz 2x16gb sticks.

I can't get the board to boot to bios, I get Q code 12 for about a minute (which means that the board is trying to sync w/ the memory), then I get a Q code 55, which as far as I can tell, means it failed. Adata says the memory is supposed to be comparable, is there anything I can do to get it working? Should I buy another memory kit? If I can't get to bios then is there any troubleshooting steps I can do other than trying the different dimms and clearing CMOS?

Facts :

The two just don't match. You bought the wrong RAM, so better return it and ask for reimbursement.

Choosing the right RAM is a complicated process. You can see some of the complexity in the post What exactly is the cause of RAM incompatibility?

That's why you need to carefully use documentation and aids by RAM manufacturers such as Crucial for being sure of getting the right RAM. Using Crucial or any other RAM manufacturer is safe, because Crucial guarantees compatibility.

DDR5 memory compatibility is still very hit-or-miss at this point.

Try to put in a single stick and hope that it will boot. Then try to do a BIOS update (which will hopefully increase compatibility).

If your board has a "USB BIOS flashback" option, you might be able to flash the BIOS directly from a USB flash drive without needing working memory.

You can also try to increase the DRAM voltage a little bit, if you're brave enough. This will cause extra heating in the DRAM chips and waste a bit of energy, but shouldn't otherwise have any negative side effects.

Worst case, you'd have to borrow (or buy) a stick of compatible memory to get into the BIOS.

Check the motherboard's memory QVL

If your RAM is not on the list then you bought the wrong RAM.

DDR5 support is notoriously finicky so stick to the QVL.
