The reason ddr5 6000 is generally considered the sweet spot for amd zen 4 is that the memory controller clock can be run at a 1:1 ratio with the the memory regardless of silicon quality (clock of 3000mhz, remember ddr is double data rate, meaning ddr5 6000mt/s is 3000mhz). For amd systems, in your bios make sure that uclck is set equal to mclck (the setting should be called something like uclk div1 mode), all non-defective zen 4 cpus should be capable of running the memory controller at 3000mhz without errors. With earlier agesa versions you'd have to win the silicon lottery in order to have a memory controller capable of running at 3200mhz with absolute stability, which is required to be 1:1 with ddr5 6400. Recent agesa updates have improved this, but it's still not absolutely guaranteed every zen 4 cpu will have a memory controller capable of running at 3200mhz. Additionally, you'll want to set your fclk to at least 2100mhz for ddr5 6400 memory, which once again not all zen 4 cpus are able to do. Therefore, the guidance of ddr5 6000 being the "sweet spot" still applies. Simply put, if you aren't interested in learning how to properly tune and stress test your system, just stick with ddr5 6000 for zen 4.
It's also important to remember that this 64gb (2x32) kit is dual rank rather than single rank like the 32gb (2x16) kits you'll normally see. There are some (very) minor performance benefits to having 2 ranks per channel, though this also means you won't be able to push the clock of this ram as high with overclocking.
Ultimately, if you truly need 64gb of ram, this is a rather good price. This is the cheapest I've seen in a while for a 64gb kit from a reputable manufacturer with hynix memory chips, which are the the best chips currently available (all higher end kits are simply using better bins of these chips). However, I'd caution gamers and those who don't have memory intensive workloads that require massive amounts of ram to stick with cheaper 32gb kits. Having 32gb is already overkill for gaming and essentially all non-productivity use-cases, and trying to future-proof based on capacity isn't worthwhile at all. A few years from now, if you end up needing more ram, you'll be able to get higher capacity and faster kits for less money.

Side note, I have this ram kit on my new build (early 2024). One ever had 1 issue, it has been troublesome to get the RGBs to sync with Aura (ASUS lighting controller). Sometimes they sync just fine, sometimes they do their own thing.

It kinda stinks that the coupon is applied after tax is calculated, so you're paying tax on the original price.
For those new to ddr5, note that you can't really use all 4 slots on your motherboard if you want to get the full speed out of it. Just stick to using dual channel.
this is how ALL of my custom gaming PCs have gone since 1996. by the time i need more power, nothing is made that will fit my motherboard. maybe if you build a budget PC and need more power in say 2 years, this could work. but never has for any of my 5 self built high end gaming PCs. they were all just a snapshot in time of gaming hardware, but lasted 5-9 years without anything more than extra storage (which i cannot use in my new PC because they are outdated).
to not know this strong possibility is to do a disservice to just say "upgrade later" unless you want to pay an arm and leg for parts not made in 3 years. you will likely never get the chance to do a upgrades as you suggest to any high end PCs.
you think im wrong? okay. dont really care. bye.

Original price * Tax * Discount
$215 * (New York Tax Rate) * 0.8
will be the same price as
Original price * Discount * Tax
$215 * 0.8 * (New York Tax Rate)
If you do the tax first, then the discount comes out bigger. If you do the discount first, then the tax comes out smaller. But the final price is the same either way. Try it out.

The formula would be more like
(215 * .8) + (215 * tax rate)

Funnily, even though they do the discounts and tax differently than I thought, the order still doesn't matter.
