Hey guys. I just bought a Corsair i8100 desktop gaming PC which comes with 64GB of RAM. I know, that's plenty. I'd just like to max it out to 128. I was told by Corsair not to mix kits, which I've heard in the past and other have speculated doesn't matter if it's the same frequency, etc etc. My question more so is, corsair told me that with DDR5 and 4 slots, it's unstable. Is this true as a whole or just with their own memory? I know they wouldn't have recommended somebody else's memory. If the DDR5 issue has been resolved whether it be through a BIOS update or whatnot, can I mix corsair memory (32x4 from two different kits as they only sell 32x2) or are there other recommendations? It's got an RTX 4090 and a core i9 (13900KS). The current modules in there are DDR5, 5600mhz 32x2. I don't know what the C rating is on them though.
