4 sticks can be problematic for XMP, compared to 2 sticks. Also, I don't see "cmw32gx4m2z3600c18" on the Strix Z690-A Gaming Wifi D4 Memory QVL. That looks like it's a 32GB kit of 2 DIMMs, and it's generally inadvisable to combine multiple kits of memory if you can avoid it.
I strongly suggest picking something that's on the QVL, and make sure it's an exact match for the listed part number. For a 4 DIMM config, make sure the "Socket Support" column is "1,2,4"; any that are only "1,2" are for single or dual DIMM configs (and not quad). Use the filters on the QVL page to narrow down the search.
You do stand a reasonable chance of getting 4 sticks of DDR4-3600 to work (faster than that or DDR5 is tricky with quad configs). I have 4x16 Crucial Ballistix DDR4-3600 working nicely on X570S, but you might struggle to get those as Crucial/Micron have exited the enthusiast market for now.
Thanks for the reply yeah I've tried even 1 stick enabling xmp sends the fans into overdrive and the cpu goes into overheat
I bought this motherboard months ago. I installed some corsair cmw32gx4m2z3600c18 64gb x4 sticks of 16gb. Xmp won't work so instead of running at 3600mhz they're running at 2666mhz. Tried the bios updates and different profiles. Now looking to change the Ram does anyone have this motherboard and what ram have you got running with xmp ? Looking for some RGB ram. Thanks.
