The new release G.Skill Trident Z5 Royal DDR5 RGB is currently best RAM. Try the 7000+ speed for better performance.

DDR5-6400 CL32.

Running a 14900KS on a Z790 Dark Hero, I've achieved 100% stability at 7600MHz using a G.Skill 7800 CL36 kit. While it couldn't maintain 7800MHz, I simply lowered it to 7600MHz without adjusting timings or voltages. High-end Z790 motherboards like this can easily handle 7200MHz+ speeds. Given the investment in such a premium motherboard, it would be unwise to pair it with slower DDR5 memory. Maximize your system's potential by choosing RAM that matches your motherboard's capabilities, ensuring you get the best performance from your high-end components.

Get G.Skill DDR5 or Corsair DDR5 memory.

Higher DDR5 speed ratings often lead to stability issues. Manufacturers are frequently releasing BIOS updates to address DDR5 compatibility. Personal experience shows that slower, supported RAM configurations tend to be more stable. The relocation of the RAM controller to the DIMMs in DDR5 introduces new variables, making stability challenging across all motherboards.

Hi there! The ASUS ROG Z790 Dark Hero is an excellent choice for a high-performance build. Regarding DDR5 RAM, here are a few thoughts based on my experience and research:

• The Dark Hero officially supports DDR5 speeds up to 8000MT/s, which is already extremely fast. Overclocking beyond that is possible but depends on factors like the specific RAM kit, CPU IMC quality, and manual tuning.

• From what I've seen, the best current DDR5 dies for overclocking are Hynix A-die and Micron A-die. Samsung chips tend to clock a bit lower. I'd look for a kit using one of those ICs rated for 7200MT/s or higher.

• Realistically, with a 2x16GB Hynix A-die kit, you can probably expect to hit around 8000-8400MT/s on the Dark Hero with some manual tweaking. Micron A-die should be able to reach similar speeds. 4x16GB configs may clock 200-400MT/s lower.

• Voltage is important for DDR5 OC. Most kits top out around 1.45-1.5V daily. The Dark Hero has a strong memory VRM that can handle this. Temperatures are also critical, so airflow over the RAM is advised.

• Timings matter too, not just frequency. Look for kits with tight XMP timings that have headroom to optimize further. Many 7200 kits use 34-45-45 timings which is a good starting point.

Some great high-end kits to consider:

• G.Skill Trident Z5 RGB 7600 CL36
• TeamGroup T-Force Delta RGB 7200 CL34
• Corsair Dominator Platinum RGB 7200 CL34

Of course, DDR5 is still maturing and new ICs may raise the bar higher. But those are some of the best current options to maximize performance on a Z790 Dark Hero. Let me know if you have any other questions!

I love Corsair DDR5 memory.

DDR5 7000+ is recommended.
