Chinese Company Jiahe Jinwei Begins DDR5 Memory Mass Production

We have seen a number of announcements from key industry players about the introduction of DDR5 memory but today's news from Chinese company Jiahe Jinwei marks the beginning of DDR5 mass production. The company announced that DDR5 RAM from Micron had arrived at its facilities and that memory module production could begin. Jiahe Jinwei is the fourth largest memory manufacturer in China and owns memory brands such as Guangwei and Asgard which have recently announced DDR5 modules with capacities of up to 128 GB and speeds reaching 4,800 MHz. Intel is expected to launch their 12th Generation Alder Lake processors later this year with DDR5 support while AMD will introduce support with Zen 4 processors on a new AM5 socket.

I still expect Adler Lake to be mostly paired with DDR4 motherboards. DDR5 will be expensive and huge latencies will negate most of the speed increase, so it will only make sense for select uses.

DDR5 will have about the same latency as DDR4.

That's a correct assumption.

To me the main point of DDR5 would be the forced ECC implementation.

From JEDEC spec, DDR5 latencies are the same as DDR4, that won't be a problem.

It will have the same latency when it matures...

I will wait for it to mature first. Never buy into a new generation of RAM early.

The forced consumer-grade ECC is not going to be the same as the optional server-grade ECC. There's a good explanation over at Anand's, and Wikipedia too mentions non-ECC DIMM variants.

I'd say the same about the first generation of DDR5 memory controllers.
