What goes unsaid in the article is that this will likely only work with Intel's Arrow Lake? Arrow Lake isnt being launched until next month though, so official specs are not available yet. And the full 9600 speed will very likely require overclocking. It doesnt appear Zen5 can get anywhere close those speeds.
These are part of a new generation of DDR5 modules that add a clock driver to the module itself, rather than relying entirely on the clock signal coming all the way from the CPU's memory controller. That is expected to significantly change the game for DDR5 overclocking, and expectations based on the limitations of configurations lacking the clock drivers may not be accurate. I expect we'll see 6+ months of firmware…
did they also make a compatible motherboard ? because I can't get mine to go past 4800Mhz when my RAM is rated for 6400Mhz with AM5 CPU. for those who hadn't done this for a while, PSA: motherboards these days have a RAM compatibility list on their product page, check it before overspending on RAM.
More than the specific list of which RAM is compatible check the table of how many slots/GB is supported at which speed. 1x 8 GB DIMM is a lot easier to drive than 4x 48 for example. Also keep in mind a lot of it depends more on the CPU than the motherboard itself, though both play a part, and the QVL should be a "safe bet". Particularly if you're willing to throw a bit of extra voltage at the RAM. CUDIMs should help…
Worth though. Much cheaper way to get a few extra percentage points than custom liquid cooling. And since every game where you would care about max FPS is bound by single threaded performance fast RAM is it.

Looks like it can get to DDR5-8400:
> Finally, we have some absolutely killer RAM. The G.SKILL Trident Z5 RGB series is one of that vendor's top brands, and this is among the top models that it offers. Clocked at a scorching 8400 MT/s with a CAS latency of just 40 cycles, this is the fastest RAM we can reasonably recommend for Ryzen 9000. It comes in the form of a pair of 24GB modules, and using it with Zen 5 could be as easy as just flicking on that XMP switch.

Does that count as "anywhere close"?
The number of performance memory chips I’ve had that had to be downclocked from their xmp profile for stability is ridiculous. It’s gotten to the stage where I’d recommend only buying memory from the first party suppliers (eg. only buy Samsung or Hynix memory). The gaming companies like the above are simply taking that memory and overwriting the xmp profile while adding some flashy but useless heat spreaders.
People should be much more sceptical than they are being here. Setting the xmp profile of Hynix or Samsung memory chips is right up there with formatting usb keys way over spec. Did you know Hynix or Samsung already binned these themselves and set them to a lower spec?

Hynix, Samsung, and Micron bin the chips for what speed they can operate at with a 1.1V supply. These enthusiast modules are using chips binned for the speed they can hit with 1.4V. The XMP/EXPO profiles don't come from Hynix, Samsung, or Micron.
China based firm named Asgard with product names like Thor? Whats going on here?
Heck, If I look real hard I might even find some California based companies that don’t pull exclusively from ancient Californian lore.
That being said, ancient mythology isn't something worth gatekeeping. And anyone who gets real uppity about (specifically) Norse or Celtic mythology instantly starts triggering "closet/academic racist" vibes.

That's a bit of an exaggeration. What matters are DIMMs per channel, and ranks per DIMM. Consumer systems have at most two memory slots per channel, so 2x 8GB modules installed correctly is just two separate instances of one DIMM per channel, and 4x48GB is two separate instances of two DIMMs per channel, with each module being dual-rank.
The best configurations for overclocking are supposed to be motherboards with only one memory slot per channel, so that when operating with one DIMM per channel there are no empty slots providing stubs of wiring that degrade signal integrity. But very few motherboards restrict themselves like this for the sake of memory overclocking.

> flashy but useless heat spreaders
The funny thing about heat spreaders on SDRAM is that they originated as a skeuomorph of RDRAM modules from the early Pentium 4 days, but everyone's pretty much forgotten that by now, so the market is essentially flooded with "retro" memory for no obvious reason except "everybody else does it".

Though I'd hope they'd finally start doing it considering the per DIMM capacities DDR5 brings (32 GB, with 64 GB planned), and most consumers really not going for capacities that'd require 2 DPC (DIMM per channel).
1 DPC should've been the default by now with the amount of 1 DPC and 2 DPC boards swapped, as it's just making things worse in the most common use case
