CMK8GX4M1A2400C16R Memory concerns on B350 Tomahawk

[poetg]

I just built a new PC; it's an R5 1600x on a B350 tomahawk motherboard, and I have a few probing questions I can't seem to find answers to online.

*Background info: It is a 2400 Corsair Vengeance LPX 8GB stick, and I can't find all that much documentation on it through msi or corsair's websites. I can overclock it to 2666 using the "Memory Try It!" feature with stock timings in my bios (updated to latest version, 1.9), but won't be trying anything higher until I get my second stick. This RAM technically isn't even on the msi support page for my mobo; I kind of ordered the RAM before checking and still got a stick that OC's beyond its listed speed in my system through blind luck.

Questions:
1. What rank is my RAM? It isn't listed anywhere online. (Model #: CMK8GX4M1A2400C16R)

2. Given current RAM Prices, I bought this one stick with plans to add an additional identical stick next payday. Is there anything I should be weary of or lookout for in this config using 2 identical sticks purchased separately?

3. Do you think I'll still be able to hit 2666 with a second stick or will I be limited to the 2400hz as-advertised (or worse, default DDR4 speed)? Is there reason to hope I might be able to OC past 2666 with 2 sticks?

I'd also love to hear from other B350 Tomahawk owners that have used this RAM and see how they like it.
Thanks.

Its dual rank without a doubt - you may still hit 2666 with 2 sticks .

Without a doubt it will be at 2t command rate though - youre probably running 1t at the moment ??

Thanks for the quick reply, but I'm honestly not 100% sure what 1T vs 2T means. From what I can find online it appears the msi bios doesn't allow users to manually select this setting, so its probably running the default config.

Oh it does allow completely manual timings & latency mate if you delve in deep.

That said the big bonus with the msi boards is that 'memory try it' option.

For those unwilling to tweak every last bit of performance manually that msi only option is a real boon & does a good job.

2t is 3-5% slower than 1t command rates.
That said 2666 2t will be quicker than 2400 1t so its a win either way for you really.

Cpu-z will show command rate on the spd tab

Thank you for the help. Wish me luck when the second stick arrives.
