So, I'm looking at upgrading my Corsair Vengeance LPX 3000Mhz CL17 2x8GB kit (OC'd to 3200Mhz CL16) with something that would squeeze a bit more performance out of my Ryzen 5 3600, and allow me to have a 1:1 fclk of 1800Mhz (currently at 1600Mhz 1:1).
Now, I'm not a fan of RGB in my own builds, and unfortunately, the PC-part market in Australia is kind of broken, so I'm stuck with these as my best 2 non-rgb options:
Corsair Vengeance LPX CMK16GX4M2Z3600C14 - a 2x8GB kit rated at 3600Mhz CL14 for $349 AUD
or
Thermaltake R017D408GX2-4400C19A - a 2x8GB kit rated at 4400Mhz CL19 for only $279 AUD (currently $249 AUD with umart premium pricing)
Obviously, the 3600Mhz CL14 would be incredible for a 1:1 fclk of 1800Mhz, but with the increased rating (and cheaper price) of the 4400Mhz Thermaltake kit, would I be better off just underclocking that to 3600Mhz CL14 (or possibly even 3800Mhz CL14 and fclk of 1900Mhz if my CPU can do it) to get the same (or better) performance for about $80-$100 AUD less?
Also, not sure how true this is, but I've heard that *apparently* the next gen of Ryzen should have a fclk of 2100Mhz? So... future-proofing with the Thermaltake kit, maybe?
It seems logical to me that this would work, since the higher rated RAM probably has the headroom to do that latency at lower speeds, but is that actually feasible, or should I just bit the $80-$100 AUD bullet, and get the Corsair kit if I want a 1:1 fclk and a CL14 latency?
Hopefully someone can help me with this, as I've done a fairly extensive Google, and LTT forum search, but can't seem to find any information relevant to my specific situation, since in almost all cases, the higher speed kit is more expensive, so it's a no-brainer for cost, but yea... it's a broken PC-part market here in Australia
