Question Different XMP profiles - how to make them work?

[mrscript_lt]

I thought I was buying almost identical RAM sticks, the main difference being LEDs.
One Kingston FURY KF432C16BBK2/32 https://www.kingston.com/dataSheets/KF432C16BBK2_32.pdf
Another Kingston FURY KF432C16BB1AK2/32 https://www.kingston.com/datasheets/KF432C16BB1AK2_32.pdf

When I enabled XMP profile - my PC did not boot. It took a while to understand what was going on, but then I noticed, that they support different XMP profiles:

• Kingston FURY KF432C16BBK2/32 supports:
  • Default (JEDEC): DDR4-2400 CL17-17-17 @ 1.2V
    
  • XMP Profile #1: DDR4-3200 CL16-20-20 @ 1.35V
  • XMP Profile #2: DDR4-3000 CL16-19-19 @ 1.35V
• While Kingston FURY KF432C16BB1AK2/32 supports:
  • Default (JEDEC): DDR4-2400 CL17-17-17 @ 1.2V
  • XMP Profile #1: DDR4-3200 CL16-18-18 @ 1.35V
  • XMP Profile #2: DDR4-3000 CL15-17-17 @ 1.35V

Mobo: Gigabyte B660M DS3H DDR4.

No issues with no XMP. When I enable XMP - PC did not boot. Is there any hope for me to make it work on some XMP profiles? Or should I just sell one pair and buy another equal instead?

Thanks for the advie

Further reading, especially "mixed memory" chapter: https://forums.tomshardware.com/thr...y-ram-and-xmp-profile-configurations.3398926/

Sell both and buy a set, where two or four RAM sticks come in one, sealed package, IF you want a guarantee of XMP working. If not, be happy with JEDEC default.

Frequent problem when not a single kit of RAM sticks. Even more frequent when sticks are not same.
Unless BIOS can support different settings in each of 2 IMC channels, XMP is not going to work as it doesn't know which one to use.
