DDR 4 shot up too. It was bad enough that instead of trying to put together a system with the AM4 m/b I already have, I just bought a Legion Go S.

It will be hit just as hard, they have stopped new DDR4 production to focus on DDR5 and HBM.

Linked in the article, DDR4 and LPDDR4 are also 2-4x more expensive now, forcing smaller manufactures to raise prices or cancel some products entirely.

DDR4 manufacturing is mostly shut down, so if any real demand picks starts there the prices will shoot up

No DDR4 is affected too. It's a simple question of production and demand, and the biggest memory manufacturers are all winding down their DDR4/DDR5 memory production for consumers (they still make some DDR5 for OEMS and servers).

They not making DDR4 anymore, so supply is limited.

DDR4 prices have gone up 4x in the last 3 months.
