Incredible price for the CL16 Corsair Vengeance LPX.
Order it in while you can. Not sure if it's the lowest price historically but definitely a reasonable price.
Mod Update 12/10: Price has increased to $97.17
CamelCamelCamel.
coming up at $108 for me

I'd probably get the 3600 CL18 if you're willing to shell out the extra cash. You can most likely clock the 3600MHz RAM at 3200MHz and achieve similar timings to this stick, plus you have the added benefit of knowing that the RAM can hit 3600MHz if you ever need that.
Based on this calculator 3200 @ 16 should be the same latency as 3600 @ 18 https://notkyon.moe/ram-latency.htm
But I believe for AMD more raw MHz will achieve better performance?
Yea, on AMD you'd be better hitting 3600MHz, as by default infinity fabric clock is 1:1 with DRAM clock, and it's been proven that infinity fabric clock is pretty much the most significant performance factor for AMD CPUs. Running 3200MHz RAM you'd be at 1600MHz fabric clock, but 3600MHz would be clocking in at 1800MHz. May not seem like much, but for AMD, that can net significant performance improvements. I think LTT did a recent test on this, and showed that running 2133MHz RAM with a 1900MHz infinity fabric clock netted greater performance than just running stock 3200MHz RAM. EDIT: Here's the link to the video, doesn't seem so "recent" after all, skip to 4:10 in the video to see relevant graphs: https://www.youtube.com/watch?v=iHJ16hD4ysk
@joshau: There is no significant performance
Improvements in the LTT video at least. At 1080p in games you are heavily gpu bound and already over 120fps. 8 FPS higher in the best case scenario is not a noticeable difference . At 1440p and 4k these ram speed differences matter even less .
At 1080p in games you are heavily gpu bound
It's usually the opposite. At 1080p, you're usually CPU bound, especially when running a RTX 2080 Ti. This is why a lot of reviewers will benchmark games at 1080p on RTX 2080 Ti's when they want to test CPU performance.
At 1440p and 4k these ram speed differences matter even less
I agree, but then we're not talking about CPU performance anymore, as GPU will be the bottleneck at those resolutions, so RAM is irrelevant. The conversation is about CPU performance and RAM, so benchmarks at 1080p are really the only thing that matters (among other workstation related benchmarks).
There is no significant performance improvements in the LTT video at least.
I wasn't inferring that increasing the infinity fabric clock will result in improvements that are noticeable to everyone, I was just explaining that this is usually much more important than RAM frequency, as we were discussing the difference in performance between 3200MHz and 3600MHz RAM for Ryzen. You can see this in the graph from the video I linked, where 2133MHz RAM running at a stock infinity fabric clock of 1066MHz is almost 10% slower than the exact same memory running with the infinity fabric clocked at 1900MHz. The fact that 2133MHz RAM can outperform 3200MHz RAM, just from an infinity fabric overclock, also demonstrates this. To me, a 10% gain (which can be had for free), classifies as a "significant performance improvement".
My point is, "faster RAM == faster Ryzen" isn't strictly accurate. For Ryzen, Faster RAM == Faster (default) Infinity Fabric clocks, and this is what contributes to "Faster Ryzen". Given you can decouple DRAM frequency from Infinity Fabric frequency on Ryzen 3000, we're now in a position where DRAM frequency basically does not matter, as one can simply overclock the infinity fabric separately anyway.
@joshau: Sorry, my point is that games are GPU bound and faster ram barely has an effect on frames. An improvement you can’t notice doesn’t mean anything in the real world , people are too focused on synthetic benchmarks
@piston3461: I think we're both sort of arguing the same point. Mine would be, don't worry about RAM frequency. Go into the BIOS, tweak the infinity fabric frequency, and enjoy the additional performance you'd usually get with faster RAM for "free". The benefits you get from 3600MHz RAM over 3200MHz RAM (on the AMD Ryzen platform) can be had for free from a small IF frequency tweak.
Just run aida64 on 3200mhz and then run it again on 3600mhz… You'll see quite a substantial difference with regards to read/write and latency… Then use ryzen calculator to tighten the sub timings up a little to lower your latency…Not that you'd notice a difference in real life only if the numbers do mean something to you :)
Any idea if it's a problem to combine this model (CMK16GX4M2B3200C16) with CMK16GX4M2E3200C16 (which is what I already have)? Hard to find info on the differences between the models.
Should be fine if you're running the highest timing pair… I.e set the timings to reflect the pair with the highest timing ….if that makes sense lol
Which ram is best (and cheapest) for mobo running at 2666Mhz, I assume 2x8GB (dual channel) is better than 1x16gb?
CL16 probably better at 3200 or so for future proofing?
(Gigabyte B365M DS3H & i5 i5 9400 4.10GHz
DDR4 2666/2400/2133 MHz, ECC Un-buffered DIMM 1Rx8/2Rx8 (operate in non-ECC mode)

Screw it, that's as good as any
Seeing all this cheap RAM makes me wonder if I made a mistake going for more expensive B die RAM (3200mhz CL14).
Is it a good idea to pick up a RAM kit right now if I'm not planning to build a PC till next year? Seeing as how there's been so many cheap deals lately
There seems to be a supply glut so they may get cheaper at least until early next year.

I'm not sure if the glut significantly affects Samsung bdie
Dayum, this is a good deal. I picked up 16GB of Crucial 3200CL16 a week or so ago for $114.
