What is AMD EXPO and should it have DDR5?

Besides revealing the next generation of processors, AMD announced the new EXPO standard for DDR5 . Memory. The upcoming Ryzen 7000 CPUs exclusively support DDR5, and batch tracking with EXPO certification can make a huge difference to how your PC runs.

We’ll help demystify what AMD EXPO is, how it compares to Intel’s memory overclocking benchmark, and Best DDR5 Combinations You can now proceed with EXPO support.

Before diving in, keep in mind that AMD Ryzen 7000 . processor Not yet launched. Although you can buy some EXPO kits now, you won’t be able to take advantage of them until the wizards launch on September 27.

What is AMD EXPO?

AMD EXPO, or Extended Overclocking Profiles, are built-in overclocking profiles for DDR5 memory. They are like Intel Maximum Memory Profiles (XMP), which comes in some DDR5 RAM modules as an auto-overclocking profile that you can turn on in your BIOS. The profile has already been tested and validated, so the modules are free to run with the profile on board.

Overclocking RAM It can get a lot more complicated than overclocking your CPU, which is why we saw XMP and now EXPO. It occupies a small inaccessible memory space and allows you to simply switch to the profile in the BIOS of the motherboard. EXPO may allow you to do this within your operating system, but that’s not clear yet.

All RAM works at a fast stock out of the box. In the case of DDR5, most RAM modules will run at 4800MB per second (Mega-per-second transfers) regardless of the speed you see printed on the case. The speed on the box indicates the overclocking profile of the kit. So, if you buy a DDR5 kit with 6000MHz speeds, you will need to enable the overclocking profile to reach that speed.

Inclusive, AMD says run EXPO It can result in up to 11% improvement in gaming performance. AMD also says that the EXPO kits are optimized specifically for Ryzen 7000 processors, although it’s not clear if this improvement will make a difference in performance in practice.

AMD EXPO vs Intel XMP

EXPO is basically AMD’s take on XMP, and there don’t seem to be many differences between the two. At a high level, they both overclock your RAM profiles which allow your modules to run at a validated speed. The big questions are about support.

AMD says EXPO is an open standard, which means that the validation process is often ineffective for AMD. Memory manufacturers provide their own test results, and those results should be open to the public to see. If the memory meets the standard from the test, it will come with some EXPO mark on the box. By contrast, XMP is closed. Intel validates the test results themselves, and are not available for viewing.

For years, AMD has supported XMP profiles with motherboards and processors. From now on, AMD says you’ll still be able to use EXPO or XMP, noting that EXPO may provide better optimization and that EXPO is set up to support Intel processors. Intel has not said if it will support EXPO on its CPUs. Hopefully this means your DDR5 benchmark for overclocking will be CPU-neutral, but we don’t have EXPO kits to verify this yet.

We already see some groups support XMP and EXPO, so we will likely see dual support for most groups in the future.

We don’t have the EXPO kits yet, but AMD says there will be 15 kits available when the Ryzen 7000 CPUs are released on September 27. Right now, we know about 12 upcoming kits from brands like Corsair, G.Skill, Kingston and ADATA. We believe that more DDR5 kits with EXPO support will be released until the end of the year.

Here are the AMD EXPO kits we know now:

  • ADATA Caster RGB – Support up to 7000 MTPS, XMP and EXPO
  • ADATA Lancer RGB – Support up to 6000 MP, XMP and EXPO
  • ADATA Lancer – Up to 6000 Megapixels, XMP and EXPO Support
  • Corsair Dominator Platinum RGB – Up to 5600 MTps, EXPO Support
  • Corsair Vengeance RGB – Up to 5200 MTps, EXPO Support
  • Corsair Vengeance – up to 5600 MTps, EXPO support
  • G-Skill Trident Z5 New RGB
  • G-Skill Trident Z5 Neo
  • G.Skill Flare X5
  • Geil Evo-V – Up to 6400 MP, EXPO support
  • Kingston Fury Beast RGB – Up to 6000 Megapixels, Support XMP and EXPO
  • Kingston Fury Beast – Up to 6000 Megapixels Support XMP and EXPO

Extended overclocking support

AMD EXPO is nothing new, but it makes the disparate case of memory overclocking with AMD CPUs much simpler. Hopefully, this isn’t a feature you need to be concerned about, as it appears that many vendors are shipping units with EXPO and XMP support. Regardless, you should keep EXPO in mind if you are building a new PC with AMD CPU.
