I have two 2x16 kits (64 GB combined), and I had to downclock ram so it will not BSOD windows. My trident Z5 ddr 5600 are now working max on 5000 and all is stable. Its a shame but maybe we need to wait for better bios?
Im using XMP2 + downclock from 5600Mhz to 5000 Mhz
Ive read that that is common problem with DDR5 - not working correctly when using dual ddr5 kits.

Might be a dumb question but I'm wondering if it's possible to combine two kits of 2x16GB ddr5 modules of the same model. And using XMP2. I'm assuming no but wanted doublecheck anyway.
I've found myself often using 80-95% of my available 32GB kit. And that's not even with my usual amount of chrome tabs open lol so would be nice with more stick but can't find any 4x16GB kits.
Thanks

Well, did you read this sticky: Don't combine memory sticks?
and if you check the the Z690 + DDR5 discussion here and elsewhere, you will find that basically nobody could get 2 DDR5 kits running - at least not at the rated frequency.
DDR5 has far higher capacity per module than DDR4. It is one more reason more to stay with 2 higher capacity modules than trying to combine 4 modules.

It's difficult not to sound like a broken record, but Please don't combine memory kits and ask why XMP will not work.
This is a historical issue enthusiast face that will probably continue. However, the introduction of DDR5 has brought in far more unsuspecting users seeking answers.
The main culprit is the lack of 4 DIMM kits currently on the market for DDR5. Most users where possible do tend to buy kits at the rated density, timings, and frequency. However, if you remove those kits from the market you leave a gaping void to be filled with users looking for 64GB and/or simply to populate all available memory slots.
The reason you should avoid combining kits is actually painfully simple, however, the whys and buts are best left to actual DRAM and electrical engineers.

Thanks, I was kinda hoping it would be different now with DDR5. Thanks for the reply
