Chinese Manufacturer Asgard Launches 4,800 MHz DDR5 Memory Modules
In the name of Odin, Chinese manufacturer Asgard has launched their first DDR5 memory modules to market - beating some competing western companies that are still "gearing up" for it. Owned by the much less interestingly-named Shenzhen Jiahe Jinwei Electronic Technology Co., Ltd., Asgard likewise lost some of its flair in naming these DDR5 sticks - the best they could do was VMA5AUK-MMH224W3. The modules will be available in 32 GB, 64 GB and 128 GB per-stick densities.
The initial modules don't have any flair - they're built with the same green PCB that's actually the forerunner of today's colored ones. The company hs also announced that the modules win run at a relatively mild 4,800 MHz (the DDR5 specification goes up to 8,400 MHz), and that its timings coincide with JEDEC's "B" classification, which should mean 40-40-40. The voltage likewise remains at the JEDEC-set standard of 1.1 V. The company announced that mass-production rollout will only occur after there are actual CPUs and platforms that can take advantage of the DDR5 memory spec, and said that they expect Intel's Alder-Lake, Sapphire Rapids and Tiger Lake-U from the blue team, as well as Van Gogh and Rembrandt APUs from the AMD camp. No word on consumer pricing was available at time of writing.

Think ddr4 has been dropping like a stone in water over the past year already
"NEW" anything tech-related is always expensive until it begins to gain a foothold in the market, then prices start to level out and/or drop gradually...
Unfortunately, that time is still a little further down the road for us consumers, but it IS coming, no doubt about it :)
Capitalism 101 at it's finest, which is a dish best served cold, and covered in a smooth, spicey, moohlah-based green sauce, hehehe :)
Yep I bought another set of 3600c16 4x8gb b-die for nearly half price I paid for another set of the same.
Crazy but I could not resist talk about happy and sad at the same time lol I was torn
4800 Mhz @ CL40 is 16,66ns
3200 Mhz CL16 DDR4 is 10,00ns.
3800 CL14 is 7,36ns.
4800 CL18 is 7,91ns.
So intial DDR5 latency will be double that of DDR4. Bit less when compared to standard 3200 CL16 kits.
I also calculated numbers based on speeds we should be getting in the coming years. Assuming the latency does not rise even more:
6400 Mhz CL40 is 12,50ns.
8400 Mhz CL40 is 9,52ns.
So only when DDR5 crosses 8000 Mhz at CL40 does it achieve latency parity with 3200 CL16 but it will still lose to faster DDR4 kits.
So here's hoping that they are no just hoping to brute force performance with raw bandwidth and there are some other things DDR5 does to achieve better latency than a simple Mhz/CL calculation would suggest.
Wikipedia: "All DDR5 DIMMs are registered; a "registered clock driver" (RCD) chip converts a 7-bit-wide double data rate command/address bus to the DIMM to the 14-bit-wide single data rate command/address signals expected by the DRAM chips."
Maybe wiki is wrong, but for getting specs from JEDEC you need to pay .. DDR5 SDRAM | JEDEC
There is some Micron whitepaper here: www.micron.com/-/media/client/global/documents/products/white-paper/ddr5_more_than_a_generational_update_wp.pdf?la=en
It seems there is many improvements, new commands, also On-die ECC.
Never become a beta tester for a 1st Generation Expensive Product.
Seems you know how to use Wikipedia, look up uDIMM.
DDR5 has to be registered.
Do the math.
