Are 2 kits compatible?

[lycosblood]

I accidentally bought the second kit a little differently.
1.G.Skill Trident Z Royal RGB Gold 16GB DDR4 3200MHz CL14 1.35v Dual Channel Kit - F4-3200C14D-16GTRG
2.G.Skill Trident Z Royal RGB Silver 16GB DDR4 3200MHz CL14 1.35v Dual Channel Kit - F4-3200C14D-16GTRS
My question is if I can use them all on the computer and on which slots.
My configuration is:
Intel Coffee Lake, Core i7 8700K 3.70GHz box
Asus ROG Strix Z390-F Gaming
Asus GeForce RTX 2080 Strix Gaming O8G 8GB GDDR6 256-bit
G.Skill Trident Z Royal RGB Gold 32GB DDR4 3200MHz CL14 1.35v
Cooler CPU NZXT Kraken X72
Cooler Master H500P Mesh Gun Metal
Samsung 970 EVO Series 500GB PCI Express x4 M.2 2280
Seagate BarraCuda 2TB SATA-III 7200RPM 256MB
Seasonic Focus +, 80+ Gold, 750W
I experienced some problems in xmp 2 when I put the kits on 1 with 3 and 2 with 4. Maybe I'm not doing something right ...

There is no guarantee how well they can work together. Try a higher DRAM Voltage to see if that can improve stability. If not, you may need to adjust DRAM Frequency or timings to see what they can do with stability.

Are you using the latest BIOS?

Yes use latest BIOS.I will try manually fix.
