Yes, you should manually enter all the memory timings if you're using a different RAM model.

I'm working with two matched pairs of different brand RAM. It's DDR3 and they both work at 1866Mhz with speeds of 10-11-10-30 at 1.5v. One kit doesn't support XMP, so I have to enter the settings manually. In MSI's settings (z87 g45), I've set the timings (CL-RCD-RP-RAS) but haven't adjusted all other parameters like RC-RFC-RRD-WR-WTR-RTP-FAW. Should I need to input those for each pair of modules? I've enabled "Unlink" mode, allowing me to change settings per channel if necessary. AIDA64 suggests: Patriot (XMP) @ 933 MHz with specific timings / another configuration for non-XMP kits. If I make mistakes, will memory testing fail quickly and be obvious?
The motherboard/bios should show the default timings it will apply. Opt for the more conservative settings, combine both extremes... note that certain entries are absent from Kingston; refer to Patriot’s specs instead. If you notice mistakes, increase those numbers by one. Patriot (XMP) @ 933 MHz 10 11 10 30 (CL RCD RP RAS) / RC RFC CR RRD WR WTR RTP FAW WCL 45 300 3 6 15 8 8 32 10 These will likely be conservative, most likely the RAM modules will run with tighter settings but manufacturers usually keep some flexibility to accommodate variations in chip quality and demand. You might also consider boosting the voltage to 1.51v — a small adjustment, and the memory won’t react negatively.
