But all the sales bundles have CL36 :(

I kinda doubt the difference is coming from CL36 vs CL30, but rather 7600 having to run at 1/2 UCLK.
Those 5600CL36 bundles probably perform better than 7600CL36 because of that.
The sweet spot appears to be getting as close to 6000 as possible
Better if it's CL30
I saw some good bundles in terms of value of the individual items
But they were mobo and or ram choices I would not want :(
They used to bundle SK Hynix CL30 for about 3 months.
Not watching it, stuck 6000 C30 in today l. Don't need any what ifs with my finances.
Tl;Dr you made the right choice anyway
7600 only works in UCLK 1:2 ratio so you're missing nothing.
Running mine with a kit of 5600mhz cl36 Corsair Vengeance (Samsung), from my research before buying, the difference between 5600 cl36 and 6000 cl30 was in the low single digit percentage wise. Although the video doesn't feature 5600 cl36, I'm assuming that's still the case based on the results?
Interesting, I OC my DDR 5 5600 CL36 (samsung die) to 6000MT/s (kept the same timings, otherwise it won't boot) via MSI try it and use their MSI Hyper Efficiency Mode. Curious how a 5600 CL36 set perform compared to 6000 CL30.
MSI try it is pretty good, isn't it? Makes it easy to see how far your RAM goes. Once you found the fastest one that is stable, you can use that as a baseline to OC further.
Yeah, I just enabled it and chose for 6000MT/s 36-36-36-36. I tried lower timings (saved BIOS before), but PC wouldn't boot. Fix it by taking CMOS battery out for a few seconds and loaded the previous BIOS settings.
About 7% additional maximum memory bandwidth - so if you were in a 100% memory bandwidth constrained situation that would be the maximum performance uplift. But being 100% memory bandwidth constrained is extremely rare so it's probably a marginal improvement. But hey, any extra performance for free is a good thing.

As always the gains from better ram is so small that a CPU upgrade is usualy better for MOST aplications.
Of course if the CPU is super high end as in this case, a CPU upgrade is almost impossible or, it can have equal or better bang for buck. The 3dx cpus also has less issues with slow ram because of the extra chache.
I have the CL36 as the store i bought from didn't have CL30 in stock. Does anyone know a roughly the price difference between 64GB CL30 and CL36?
Yeah, I really feel like quantity over quality is the way for ram. Much more improvement adding on GB than increasing speed
Agreed. been building pc's around 2 decades now. RAM is something that really helps longevity of a system build. I ran a 2600k with 16gb of ram for 12 years, when I bought it everyone said it was overkill. New PCs now have about 16gb often lol... enough said. New rig is 64gb 6000 cl30, basically double or quadruple whatever is standard today and you'll be set.
6000 runs in 1:1 mode (UCLK = 3000MHz)
7600 runs in 1:2 mode (UCLK = 1900MHz, slower than FCLK)
6000 CL36 is not the same as 7600 CL36 btw.
And of course you can run the 7600 CL36 kit at 6000 CL30
I haven't dipped my toes into DDR5 yet, did any of the sticks end up getting the rumored feature where they have multiple XMP/EXPO profiles or the option to save an additional one to the stick?
It would be really neat to be able to buy one with a 7600 CL36 and 6000 CL30 profile already on-board for ease of use with different CPUs. I'm familiar with setting everything up manually (on DDR4 at least) but for friends builds it's nice to have the option to help them set a profile without doing it all manually.
Hasn't that been a feature on DDR4 as well? I think one of my kits has multiple profiles and the other one doesn't. I'd assume higher end DDR5 kits have that as well.
dont forget that many kits can run at cl28 when at 6000mt/s
good luck getting even 6000 to boot on am5
I would RMA a CPU that couldn't boot at 6000Mhz
