Background on DDR5 Registered ECC Memory
DDR5 is the fifth generation of 'double data rate' memory technology. It features reduced power consumption compared to previous generations, while also boosting clock speed and memory density. That means both higher performance and lower power usage, with the potential for larger memory modules as the standard matures.
ECC stands for Error Correction Code, and in the context of computer memory it indicates the ability to detect and correct minor errors. This dramatically increases the reliability of the memory system, which is highly desirable in environments where computers are performing critical functions. There is a small amount of overhead when using ECC memory, so performance takes a slight hit compared to non-ECC options - but the trade-off is well worth it for servers and some workstations.
Further, Registered memory - sometimes also called Buffered memory - puts less of an electrical load on the memory controller chip in a computer. This in turn allows the use of much larger amounts of memory, and so is needed when utilizing all of the memory slots on higher-end server and workstation motherboards.
Due to market volatility, the exact brand and model of memory that we use can vary - but we adhere to strict quality standards and prioritize modules that use Micron or Samsung chips.
Please note that the actual speed at which memory modules will operate in any given system is a combination of several factors: the memory specs, official CPU-supported speeds from Intel & AMD, motherboard memory QVLs, and what we have found to work the best in our internal testing and qualification. If you have questions about what frequency the RAM in your Puget system will be set to, please contact your sales consultant.
At launch, DDR5-4800 seems to be the standard maximum memory speed supported by most CPUs - but that may only apply with two sticks of single-rank memory installed. With more modules installed, that maximum often drops a but lower. For example, I've seen speeds as low as 3600 specified for some memory combinations on Intel processors, for example.
