Getting memory sticks to their advertised speeds

Here is a link to the exact ram I have. https://www.newegg.com/Product/Product.aspx?Item=N82E16820231892 I know that its advertised at x99/z170. I read in the comments that it was good for Ryzen builds but might have jumped the gun and bought something that wasn't compatible(oh well if so). I have the X370 Gaming K4 board, and I've seen people have luck with certain timings and voltage(not on the same motherboard), but I was just wondering if by changing timings to 14 14 14 34 (which are the timings I've seen people have luck on) and not changing the voltage, I might be able to get the computer to POST. I'm relativity new to overclocking memory, and I've been watching a lot of videos on the subject, but mainly was just wondering if I could get the desired 2666mhz without having to up the voltage.  Has anyone with this board been able to get their memory to post at 2666? If so what timings are you using and what voltage?  Thanks in advanced.  Your link did not work for me either, but is your memory this one, the G.SKILL Ripjaws V series? https://www.newegg.com/Product/Product.aspx?Item=N82E16820231892 I recall another user of Ripjaws 5 memory in a Ryzen board posting in the forum, and he also did not have good luck with it at higher speeds. What speed can you run that memory at now? You can always try the timings you listed, that won't hurt anything, but if the memory chips on those DIMMs cannot run at those latency values even at 2133 or 2400, they won't at 2666. Another problem is the memory is only rated up to 2666. That is decent for X99, and fair for Z170. Reaching the highest rated speed is at the edge of stability for the memory chips, and if compatibility is only fair with Ryzen to begin with, reaching 2667 may not happen. I see a review on Newegg at the very top saying it works at 2666 with a Ryzen system. The very next review below it contains a comment from G.SKILL, including this: "Unfortunately, this particular memory kit is not officially certified for the ASUS X370 motherboard, so a BIOS update or additional tweaking may be necessary". Why are you reluctant to increase the voltage, or are you already at 1.35V?

Now that I say that, that doesn't make much sense, lol I'm gonna have to switch the voltage for it to even POST.  I'm currently running at 2133 1.2v with what I believe are the timings advertised on the memory kit (15 15 15 35). I'll try for 2400 and see if it POSTs at the 1.2v. If it doesn't then I'll up the voltage.
