Ooft, that's nice but it ain't gonna be cheap!

Now we just need to know if faster than default RAM speeds effect performance in a similar manner as they did with previous generations, i assume it does but i would be nice to have that confirmed before spending more than necessary.

It might be late but I don't really understand. I thought that with Zen 2 there was no need for tuned memory for a specific brand of cpus anymore. Does that mean that memory kits are usually tuned for intel cpus in general(by that I mean that shouldn't it work “optimum-ly” with either brand from the start?)? Or is this only due to infinity fabric process…? I don't recall needing specifically tuned memory kits for intel or amd when I built one of my 1st pcs which was an athlon xp barton 2500 when it just got out at that time. If someone could explain, it would be greatly appreciated.

This is all i've found so far.

Looks like it may make a few fps difference at 1080p running 3600 over 3200, not sure it would at resolutions above that. All of the measurements were at CL18 too so it's not really in depth.

This is the thing. Faster RAM, tighter timings, etc. are pointless outside of benchmarks. The cost/improvement ratio is nuts! I get wanting the best, and in the past I've definitely gotten parts that I didn't need just to get a bit more oomph, but bleeding edge RAM is just one of those things that will never make sense to me.

If you're just talking about faster RAM then I'd be inclined to agree as most of the advantage gained is lost from having to cross a clock domain, you can only send data as fast as the slowest link, however with Zen you're not just talking about faster RAM as the data fabric connecting everything shares the same clock domain as the memory controller (that changed with Zen2 but the 1:2 divider is rather pointless IMO).

By running faster RAM you're essentially overclocking the bus that connects the chiplets together.

..the only thing this is optimised for is G-Skill's profit margin.

wont be more than the Royal, if its priced more then its just a marketing thing to milk customers, the timing wont make any real difference outside of benchmarks, and even though the gains are minimal.

It's not needed, but it's a good excuse to charge more for plain RAM

For sane RAM kits (<3.7 GHz) the IF is still bound to the RAM speed

Have you seen this? TechPowerUp has a whole slew of very interesting articles on the new Ryzen 3000 series (and X570 chipset).

I asked Scan to explain a while back and never got an answer, and worse, they seem to mix up Intel and AMD specific terms so I don't think any descriptions can be trusted (Ryzen optimised ram talking about intel motherboard chipsets for eg.)

It's possible that a particular combination of latencies would suit access patterns from a particular type of CPU over another, but very unlikely as that's what more local CPU cache is used for.

Ok. Time will tell))

Apparently my Corsair LPX was meant to be for Intel boards, strange as its been powering my Ryzen very happily :/

Yea i was looking through all their testing yesterday, it seems there's not as much scaling in performance with Zen2 when it comes to memory, same with PCIe 4.0, and with X570, we're talking single digit performance gains in most situations, unfortunately i can't stop myself looking at the more expensive stuff. :)

I just ordered four of these. Don't let the listed speed mislead you. Apparently, Samsung is notoriously inept when it comes to listing correct specs on their website. The real speed (2666) is listed in the datasheet.

And yes, I'm fully aware that they are ECC dual rank modules. :D

No, hadn't seen that. Thanks :)
