G.Skill introduces the first DDR5 kits with a CAS latency of less than 30 milliseconds.
G.Skill are excited to announce extremely low-latency DDR5 memory kit at DDR5-5600 CL28-34-34-89. It’s the first time to bring DDR5 XMP specification under CL30.
G.SKILL International Enterprise Co., Ltd., the world’s leading manufacturer of extreme performance memory and gaming peripherals, is excited to announce an extremely low-latency DDR5 memory kit specification at DDR5-5600 CL28 in 64GB (32GBx2) and 32GB (16GBx2) kit capacities, under the Trident Z5 RGB, Trident Z5, and Ripjaws S5 series and designed for the latest 12th Gen Intel® Core™ desktop processors and Intel® Z690 chipset motherboards.
Breaking the Sub-30 Latency Barrier on DDR5
With a focus on breaking the limits of low latency with DDR5 memory, G.SKILL is releasing an extremely low-latency sub-30 timing memory specification at DDR5-5600 CL28-34-34-89. Setting a new bar for low-latency timing performance, this memory specification with CL28 marks a new era of high-end DDR5 memory.
See the DDR5-5600 CL28 64GB (32GBx2) memory kit validated with the Intel® Core™ i7-12700K processor and ASUS ROG Maximus Z690 Hero motherboard in the screenshot below:
Availability & Specifications
The DDR5-5600 CL28 memory specification in 64GB (32GBx2) and 32GB (16GBx2) kit capacities will be available under the Trident Z5 RGB, Trident Z5, and Ripjaws S5 series in late May 2022 via G.SKILL worldwide distribution partners. For detailed specifications, please refer to the table below:

I'm more interested in if AMD can take advantage though. Imagine if AMD and Intel trade places on RAM compatibility where Zen 4 is the leader when combining high frequency and low latency? I could get used to AMD and Intel trading blows.

yup that's what im talking about
early ddr adopters slways get suckered
ddr4 was poor value up until 3200 started to get decent pricing when 8700K launched
at this point the absoulte cheapest ddr5 i'd be interested in is 300eur,and it's 6000 c40 kits that only perform well when overclocked.
meanwhile,ripjaws 4400 c19 is 156eur.
tuned vs tuned you're going to see a couple of percent difference at best,with lower resolution and a high end card with both running super high amounts of fps.
this goes for 140eur

lol if people still get ddr5,unless they're enthusiasts and they know they're practically throwing money away cause this in 1:1 mode will match most mid-range ddr5 like 5200,5400 or 5600.
not only does ddr5 need to drop in price,to get to acceptable levels of price/performance intel and amd need to get their current cpus to do 5200/5200 is 1:1 mode.They're only 1200mhz away from that goal at this point so good luck,you'll need +6000mhz sticks with low latency to compensate for the 1:2 mode.
it was never a good deal to run ddr4 in 1:2 mode,ever,why would it be now when it costs you twice to get ddr5 over ddr4.

I’m so old that I remember buying and using CAS 2, Lower the cas, tighter timings ALWAYS made any system run faster than just super high mz frequency. Seeing CAS 28 and more makes me laugh, it’s so HIGH!

28 is super low for ddr5
mainstream kits are 36-40

It's all nice but thhe cost is crazy,especially when late ddr4 is really good in terms of price to performance.
6400 c32 kits is where things start to get interesting and ddr4 is clrearly starting to fall behind.
now go check how much these are.
ddr5 is for enthuisiast rigs,no one who wants to get a 200-300eur cpu wants to have to drop 400 eur on memory.
Dont you remember when ddr4 kits costed the same? 16gb 3200 was like 300eur when haswell-e landed.
