[SOLVED] Two DDR4 with same specs except tRFC, works together?

[rowstah]

Hi.

I just bought a new DDR4 16gb (single) and removed my previous memory of 8gb. Only have 2 slots. Is it possible to use the 8gb (second slot) also? I've checked the specs, and they match on everything except on the tRFC where my new ram has 374 clocks and the old 278. It's no risk testing?

Thanks in advance.

You honestly won't know till you try them together.

Not much risk in testing - just don't break a RAM slot.
Even if it works, with different sized/type RAM sticks, your system won't run in dual channel mode.
Also, just booting into Windows does not mean it's stable. Be sure to boot off a Memtest86+ USB/CD and let it run for a minimum of a few hours. If you don't get any errors you should be good to go.
