Question about Ram Kits

[WhatsTheWifiPassword]

Hi, so atm my mobo is x370 sli plus, and checking over the QVL of compatible first gen RAMs I do wonder this question:

 

If the QVL has compatibility of a 2x8gb ram kit, will their 4x8gb or 2x16gb ram kit be compatible with the motherboard

(as seen on amazon's additional offers of their other variants to the kit) 
also for 4x8gb sticks are they 'bin-ed' such that all ram sticks have the same chip type? 

 

thanks

All DDR4 work on it, they just may not run at their rated speeds (let's say 2400MHz max at worst).

 

but just because the 2x8gb kit can run a certain speed doesn't mean more sticks or capacity will work, that's why the larger capacity kit wasnt listed. also just because the board can do it doesn't mean the CPU's memory controller will do it.

so spend $100 more on ram for the same 32 gb that I could get for 150

at that point you might as well gamble, at worst you just run them slower

my luck wasnt here, old kit was hynix ram, new kit was samsung ram...

You can always drop more, if you dont know how to stress test and tune the memory

i'm using memtest86 
also btw do you know if I buy a 4 stick kit, will they ship 4 sticks of the same die density/ memory manufacture?
