If everyone went for DDR4 and DDR3, surely the cost would go up. There is no additional supply there, as they are no longer being made.

Currently trying to source a large amount of DDR4 to upgrade a 3 year old fleet of servers at a very unfortunate time.

It's very difficult to source in quantity, and is going up in price more or less daily at this point. Vendor quotes are good for hours, not days when you can find it.

We're looking to buy 1TB of DDR5 for a large database server. I'm pretty sure that we're just going to pay the premium and move on.

		And that’s why everybody’s B2B these days. The decision-making people at companies are not spending their own money

At some point that’s true, but don’t they run the n-1 or 2 generation production lines for years after the next generation launches? There’s a significant capital investment there and my understanding is that the cost goes down significantly over the lifetime as they dial in the process so even though the price is lower it’s still profitable.

		This is only true as long as there's enough of a market left. You tend to end up with oversupply and excessive inventory during the transition, and that pushes profit margins negative and removes all the supply pretty quickly.

		Unless plans have changed, the foundries making DDR4 are winding down, with the last shipments going out as we speak.

Undoubtably the cost would go up, but nobody is building out datacenters full of DDR4, either, so I don't figure it would go up nearly as much as DDR5 is right now.

You can see the cost rise of DDR4 here.

Awesome charts, thanks! I think it bears out that the multiplier for older hardware isn't as extreme as the newer hardware, right?

~2.8x for DDR4, ~3.6x for DDR5. DDR5 is still being made, though, so it will be interesting to see how it changes in the future.

Either way, it's going to be a long few years at the least.

Unless the AI bubble pops.

		One possible outcome is the remaining memory manufacturers have dedicated all their capacity for AI and when the bubble pops, they lose their customer and they go out of business too.

That's the Avarage price for new DDR4 which has dwindling supply. Meanwhile used DDR4 is being retired in both desktops and data centers.

		DDR4 production is winding down or done. Only "new old stock" will remain, or used DDR4 modules. Good luck buying that in quantity.
