Bewildered enthusiasts decry memory price increases of 100% or more — the AI RAM squeeze is finally starting to hit PC builders where it hurts (www.tomshardware.com)

"I've been saving for months to get the Corsair Dominator 64GB CL30 kit," one beleagured PC builder wrote on Reddit. "It was about $280 when I looked," said u/RaidriarT, "Fast forward today on PCPartPicker, they want $547 for the same kit? A nearly 100% increase in a couple months?"

I just got a 2x64GB 6000 kit before its price skyrocketed by like $130. I saw other kits going up, but had no clue I timed it so well.

...Also, why does "AI" need so much CPU RAM?

In actual server deployments, pretty much all inference work is done in VRAM (read: HBM/GDDR); they could get by with almost no system RAM. And honestly most businesses are too dumb to train anything that extensively. ASICs that would use, say, LPDDR are super rare, and stuff like Hybrid/IGP inference is the realm of a few random folks with homelabs... Like me.

I think 'AI' might be an overly broad term for general server buildout.

why does “AI” need so much CPU RAM

It doesn't really, though CPU inference is possible/slow at 256+gb. The problem is that they are making HBM (AI) ram instead of ddr4/5.
