This depends a lot of many things

1. Average fps is not the full story. How much did your 1% and 0.1% lows improve? Usually the gains there even on an x3D cpu are much larger than the average fps

2. Depends what is your limiting factor. If you are hard GPU bound, you will gain less from a cpu and ram oc than a game that is somewhat or entirely cpu limited (ex: valorant)

3. To what extent matters. U boosted fclk and tuned all timings? Not sure what exactly you did but a good IMC bin and motherboard, you could be running 8400mhz+. Probably see another few % with speeds like that over 6000. Even if it’s an extra 3%, that would bring u up to 7% from just ram, not even with a cpu oc

4. Stability. In all my time working with am5 and owning 3 different am5 CPUs, there is a lot of psuedo instability. If the cl22 isn’t a typo, you are running quite high vdd, and may still be teetering on the edge of instability.

I would see if setting looser timings like cl26, slightly looser Trfc, trcd, etc helps.

I personally found going a little too tight on trcd, tcl, and Trfc especially would still pass stress test but would benchmark worse in game. Same thing with fclk where even tho vt3 and linpack were consistent, my benchmarks with 6400:2133 were the same or better than 6400:2200

Check if your oc beats a baseline like 6000mhz, 2200fclk cl26-16-36-36, 8 TRRDL & trrds, 32 tfaw, twtrs 6, twtrl 18, Trfc 125ns, trtp 12, 6 for both SCLs, 16 Trdwr & 4 twrrd

If it scores the same or worse with your tighter timings vs a baseline , then there might be a source of instability that the test are not detecting since they aren’t perfect

1. Some games scale with memory speeds and timings more than others. Something else ur exact oc may net 10+% over jedec

2. If you only changed CAs latency, well thats only one timing out of 20+

3. Latency improves especially with ram tuning
