So it's not memory speed bottlenecking it, GPU limiting it?

The only way you are going to get faster speeds is if you buy ram thats maybe 7800mhz and CL34 or something tighter, so already has the speeds as well as the tight timings of 6000mhz kits now, even then then IF on AMD chips is going to run 1:2 as its not going to do 3000, currently it tops out around 2200 if you get a golden chip.
something like this: https://www.gskill.com/product/165/374/1668740011/F5-7800J3646H16GX2-TZ5RK
you could probably push that to 8000mhz with slightly tighter timings.
Thisnis even at 720p cpu bottlenecks
It's the higher latency from the timings, we need kits with better timings, just adding higher speeds isn't doing anything above existing 6200 CL30 performance

Fabric bandwidth bottleneck. To quote one of our hardcore zen guys from our oc group:
“max theoretical bandwidth for Zen4 is actually 72gbps
2x36gbps GMI3 links
but for that you'd need above 2200MHz FCLK and that's not gonna happen
so, at 2200 it's 70400mbps
(FCLKx32=bandwidth)”
You will see gains in synthetics like geekbench 3 mem tests but good luck in games.

From what I've read so far gaming performance is actually worse when hitting these speeds on the ram? I don't think the update is out yet for me on the MSI tomahawk x670e anyway.

Hopefully I will get 6400 out of the 6000mhz ram from corsair then doubtful ... but will try it. Waiting on MSI to release the update for my board.

What are the current big bottlenecks in gaming performance?

Apparently 6200mhz 1:1 is the new sweet spot, previously 6000mhz anything over requires you to run the IMC at 1:2 unless you have a golden chip.
AMD Ryzen 7000/7000X3D CPUs are Slower with DDR5-7400 Memory in Gaming | Hardware Times
The other day, AMD rolled out a new AGESA update that significantly boosts memory overclocking performance. Users have already reported overclocks of up to 8,200 MT/s using the new BIOS, and that too on budget hardware. Quasarzone tested the Ryzen 7 7800X3D and the Ryzen 9 7950X using high-speed...

Im going to be building a new system soon, i know im going with a 4090 and a 7800x3d but not yet decided on mobo and RAM. I'll be interested to know what the best RAM/mobo combo will be with this new agesa.
suspect it will still be the highest speed you could run 1:1 as it was in AM4.
So 6400ish on a good motherboard

ATM im thinking to go with the f5-6400j3239g32gx2-tz5rk gskill trident and the x670 aorus elite.

In games X3D chips don't really benefit from higher RAM speeds anyway, this should be tested on a none X3D chip.

It’s too broad statement. Some games probably will benefit from faster memory on some systems.

waiting on the b variant bios this one is terrible not sure why i have lost clock speed though since when i built it it was going as high as 5.6 on some cores

This is the B version. Wrong thread?

Id go with a G.Skill kit 6000mhz EXPO kit, G.Skill have said they are no longer going to use Hynix M IC's only the Hynix A IC's and they are very overclockable, get a tight timings kit like CL30, they'll easily overclock to 6400mhz, most people tighten the timings down to CL28 / CL26
This is Hynix A Die https://www.gskill.com/product/165/390/1661410135/F5-6000J3038F16GX2-TZ5NR

no was just venting my frustration at version A with the expo 2 profile
i will be flashing to version B as soon as it drops.
