A new generation has arrived! Here is a run down of some details to know.
DDR5 UDIMM modules have the same dimensions and pin count as DDR4 modules. The most obvious difference is the position of the fool-proof notch.
The notch location / gap between pins on the memory modules has changed with DDR5, preventing newer modules from being accidentally fully inserted into older DDR4 slots and vice versa.
A PMIC (Power Management Integrated Circuit) on the module helps reduce the role of the motherboard in power management by handling most of it on-chip. It is essentially the brains behind an intelligent voltage regulation system that facilitates the configurability of voltage ramps and levels while offering current monitoring features. This allows for the most complete control of individual memory modules to date.
Compared to DDR4, DDR5 has double memory banks, burst length, and prefetch to improve capability and efficiency.
Standard DDR5 modules will feature two independently addressable 32-bit sub-channels. This will especially help high end multi-core processors more efficiently manage the retrieval of data from memory by having access to multiple separate locations.
All DDR5 DRAM modules feature the ability to correct errors before a bad bit leaves the module. As DRAM density increases (due to wafer lithography shrinks), the potential for data leakage within modules also goes up. ODECC (On-Die Error Correction Code) catches any such bad bits early on and corrects them.
The current JEDEC standard for DDR5 memory is DDR5-4800 CL40-40-40 @ 1.10V
The highest JEDEC standard for DDR4 is DDR4-3200 CL22-22-22 @ 1.20V
DDR5 DRAM modules start with a baseline memory speed of DDR5-4800 compared to DDR4-3200, a +50% increase.
Maximum capacity per DIMM jumps from 32GB to 128GB.
Transfer rate improves from 25,600Mb/s to 38,400Mb/s
As with previous generations, mix matching and using multiple memory kits in a system is not recommended as results are not guaranteed. However with DDR5, this appears to be even more important so make sure to use only a single kit of memory in each build.
Currently with the latest Intel Z690 chip set and supported processors, DDR5-5600 is an ideal performance point for most users and builds. For extreme users and overclockers, DDR5-5600+ can be complementary with a capable motherboard and CPU. For guaranteed results, always follow the G.Skill QVL or RAM Configurator.
