KLEVV is at it again and brings us another CRAS product. What we have here today is the CRAS V RGB DDR5-6400 memory kit marketed towards PC enthusiasts and gamers alike. Follow along as we test this memory kit and see how it stacks up to the competition!

6400 C32 seems pretty good for 1.35 V, considered my 6800 Trident Z5 kit needs 1.475V for 6400 C30.

Next-gen DDR5 is going to scream.
 
RAM @7200 MHz is not expensive right now and it is worth it.

Unfortunately, 7200 is not an option for people on Intel Z690 or AMD platforms, unfortunately. 6400 is the sweet spot for high-end Z690 platforms, and C30/C32 are about the tightest timings DDR5 will operate at this frequency. 6400 C30 is very hard to meaningfully improve upon, unless you purchase an 1DPC Z790 motherboard known to be great for stretching DRAM clocks (boards such as the MSI MPG Edge ITX, Maximus Apex or Apex Encore, Aorus Tachyon, EVGA DARK Kingpin, etc.). Even then, the gains that you will achieve operating a i9-13900K, KS or 14900K with DDR5-8000+ are in the single digits compared to tightened 6400. For AMD I believe the sweet spot remains around DDR5-6000, even after the new AGESA that allows higher clocks, due to limitations of the infinity fabric/FCLK ratio.

Anyhow, highest stable 24/7 clocks I've seen on Z690 was 6800 on a ROG Maximus Z690 Formula, and that was still at 1.5 V. Ironically, the exact same RAM kit I have - my MSI MEG Z690 ACE cannot clock it that high.
 
@Dr. Dro going back to a z690 with a 13900K that can do 8200, I found anywhere from 6600 to 7200 worked after manually setting everything. The Gigabyte Z690 Tachyon (2-slot) maxed out at 6933 for the 12900K and 7800 for the 13900K. So 6400 and above is differently questionable for most z690 motherboards. I agree that 6400 is a good fit, plus if you binned to 32, probably likely CAS 30 will be achievable as well with some voltage tweaks.
 
KLEVV DRAM is always going to be SK Hynix IC which is a pretty big advantage as long as you're willing to do manual OC (assuming 6400 isn't enough). Good to see they've got good performance at a relatively low voltage.

I was aware of these things. But aren't >90% of the people currently purchasing DDR5 RAM for an Intel setup persons who are doing a new build?
In many benchmarks, the difference between 6000 MHz and 7200 MHz is around 5% difference in results. I think that is worth it when you know that 7200 MHz RAM is not expensive.
 
oh these specs are neat! 64-32-16...
