Once again, the subject is not you buying your processor individually (enthusiast hardware), but your run of the mill, 80% of people have it OEM stuff. Your tower PC bought at the local supermarket, your laptop, all of these will have a combination of:
* CPU not supporting such a high rate
* Motherboard not supporting it
* CPU lost the silicon lottery and has a bad memory controller that struggles above basic rates
* vendor put in DDR5-4800 in anyways to save up on costs
* BIOS not up to date on your motherboard

And I’m looking at a press release from 2021 that says it is. > JESD79-5A expands the timing definition and transfer speed of DDR5 up to 6400 MT/s for DRAM core timings and 5600 MT/s for IO AC timings to enable the industry to build an ecosystem up to 5600 MT/s.
- ohgodplsno 4y agoJesus fuck, thanks for reminding me that HN is full of needlessly pedantic assholes. JEDEC _default_, not standard. Satisfied ? As in, the default value is 4800, and now, with JESD79-5A, JEDEC also recognizes that DDR5-6400 can exist. Not "is the standard".
