It will not exceed 7950x 2800mhz and less than 3000 points in cinebench 23

This week a long-awaited shipment of parts arrived for a new box consisting of
PSU: Corsair RM1000x
m2: Wrath of the Renegade
MB: Asus proart x670E
Cup: 7950x
Coolant: Noctua D15
Ram: Corsair 5600MHz CMK32GX52B5600C36 Went to MB’s QVL, which was probably stupid because DOCP doesn’t work because it’s actually intel’s XMP memories.. Now order the new one from AMD.. CMK32GX52B6000Z36.

I can get the memories are about the right speed and the right latency, but that’s not the big deal.
it prol! My Cinebench(23) results are on par with my old I7 3770k. Just under 3000px in multithread.
Yes, you read that correctly, under 3000, I think there is really a problem if you are under 30k..
Adding some pics, as you can see at full load the proll is under 2800mhz, doesn’t draw watt amps or anything else to speak of and it’s great. He simply refuses to go higher. Nothing in bios is set, everything defaults to auto etc. Updated to the latest bios, 0922, no difference.

However, CPU-z is showing a higher clock for some reason..? This is also under full load in Cinebench.

Fully fresh Windows installed twice, tested with only chipset drivers direct from AMD and on install before with all drivers via Asus for the motherboard. Nothing installed besides the above, I also took apart everything at once, apart from the cooler, with the cpu, and new cooling paste. All power cables moved at once and so on. Front USB etc. is definitely connected and seems to be working fine..

Now to the point, I put Biosvardet CPU core ratio on AI optimizer Instead of autoplaying the proll starts behaving differently, it jumps at a high rate between really high and low clock under load, ie up to 5.8GHz for the next break to be about 0.5GHz lower. However, this gives a result in Cinebench of around 21K, which is a definite improvement, but still half of what the year should perform.
In addition to the clock frequency fluctuation, PPT / Watt / Amperes and so on also do the same fast rate.
The temperature rises to or close to 85°C. Look at the picture, these values ​​jump up and down many times per second.

Which makes me think I might be able to set all the values ​​manually, the only problem is that despite a bit of fiddling with the OC on both the 1700x and 3900X, I don’t have a very good understanding of all the parameters. Is there a good place to read about all of these?

My reasoning says that it should be possible to overclock regardless of whether I run the memory at a standard SPD JEDEC speed of 4800MHz.. But without knowing all the parameters, it’s hard to even start tuning.

Does anyone in the awesome forum have any clever ideas?
