I thought that wasn't possible since DDR3 or 4?

dahrkael Aug 26, 2025 View on HN

it depends a lot if the RAM is DDR4 or DDR5, those Intels really like fast memory

elcct Oct 28, 2016 View on HN

They could use ddr4, cpu supports it

bullen Oct 3, 2022 View on HN

I think it has to do with DDR5/DDR6.

That ram is slower than soldered down lpddr5 at the moment.

fulafel Oct 17, 2017 View on HN

Its own DDR4 RAM? Anyone know the bandwidth or capacity?

gautamcgoel Oct 27, 2021 View on HN

Can someone explain why this uses DDR2 instead of a more modern DDR4?

mtanski Jul 17, 2018 View on HN

Yeah, depends if you want 2 memory channels or 4 memory channels.

Or you can get a strix halo 395+ that has 8 memory channels with a max of 128gb of ram. I think it does around 400 GB/s

Zero since Haswell-EP uses DDR4.
