We're Almost There
Picking up from my last year's rant about Dual DDR5 not being up-to-speed with Quad DDR4, I was definitely not wrong, since achieving X299X where we could get lots of ram, at very high speeds, running flawlessly on
When DDR5 first came out, it also came with much needed features, and now, finally, we have ECC.
ECC, why not?
You know the reason we didn't have (ECC) Error-Correcting Code on DDR4/DDR3/DDR2 for mainstream PC's? There is Intel's Artificial Market Segmentation Yup, you can blame the blue team on that one,
In case you want to read more, you can: read from Linus Torvalds himself.
We can't leave without quoting the article above:
Torvalds takes the bold position that the lack of ECC RAM in consumer technology is Intel's fault due to the company's policy of artificial market segmentation. Intel has a vested interest in pushing deeper-pocketed businesses toward its more expensive—and profitable—server-grade CPUs rather than letting those entities effectively use the necessarily lower-margin consumer parts.
Intel's Artificial Market Segmentation
Intel's segmentation was not only for ECC, they lock overclocking for non-K SKU's. They also disable hyper-threading on chips that could easily handle it and force users to buy a physical key to run VROC (Virtual Raid on CPU) on motherboards that already come with the feature built in. So, you paid
JEDEC to the Rescue
When JEDEC was establishing the DDR5 standard, the inclusion of on-die ECC (Error-Correcting Code) was on-die ECC is a standard feature in all DDR5 modules. It is definitely a win for
Final Considerations
As of 2024, DDR5 is a little more mature now, we do have better speeds, prices did decrease a bit, availability is OK. If we go back, at the end of DDR3 lifetime, we had extremely fast DDR3 chips, it took a while for DDR4 to catch up, and I knew the same would happen to DDR5, it is not my first rodeo. But then, I wish that the timings (most notably

Ending Thoughts
Your results might not be exactly the same, so take this into account, but it already serves as a good starting point for what you can expect if you are thinking about upgrading to DDR5. As of now I don't have a 7950X3D, so I am in the dark when it comes to AMD's numbers, so take my results with a grain of salt if you're considering an AM5 build.
The methodology was simple, I kept the same timings (40-40-40-77), ran the test four times, took the
Good luck, and feel free to show me your results
Sidenote
It's worth noting that discussions about Intel's market segmentation are relatively scarce, both among public figures and in general discourse. It's essential to understand that my aim is not to demonize Intel, but rather to highlight concerns about their aggressive market segmentation, which can have negative implications for both consumers and developers. This isn't a witch hunt; it's a call for
Intel, like any for-profit company, seeks to maximize its revenue. However, when their segmentation practices create difficulties for developers and users, it's important to voice these concerns. The importance of these discussions is to prevent it from happening again, take the transactional memory disaster, in this specific scenario, only a few developers (everyone.
