7950X optimisations, anything more for me to do?

[Meddling-Monk]

OK, so I've finally started looking into optimising the new rig (finally). I know it's stable at default settings, so I can always return to those in a pinch.

So, I've currently done the following:

Eco Mode 105W is activated (FINALLY!!)
Set PTT at 142000, TDC at 110000, and 170000 for EDC
All Core PBO Optimisation Curve is at -30 (I just YOLO'd this, but it worked, so... )
RAM set to 4000Mhz, Auto settings place it at CL36, 34, 34, 64, 98, 509, 1T (As shown in HWinfo; default for 4 X RAM is 3600Mhz, which yields CL30 numbers)
Fabric (Fclk) set to 2000Mhz (from Auto)
Memory clocks (Uclk and MclK) set to 2000Mhz and 1:1 (to obtain a 1:1:1 ratio, didn't use seperate asyncronous memory because 128GB is unlikely to go beyond 4000Mhz anyway, so went for the 1:1:1 ratio instead)

Cinebench completes without issues, 35-36k score. Not that far from 37k score when leaving everything was left on Auto. Temps don't breach 70C with the fans barely moving. This compared to full auto going at 95C and only getting 1k more in Cinebench. Voltages are also lower. :: edit :: All cores now head to 4.8/4.9-5.0ghz and stay there throughout whereas the 65W Eco mode sits them at 4.5Ghz and defaults hit 4.9Ghz to 5.1Ghz.

Rig is made up of:
7950X
4 x 32GB Corsair Vengeance 5600Mhz CL36 DDR5 (RGB - I know I know, I know I go on about RGB and the pointlessness of it for me, but this was the ONLY kits of DDR5 at 64GB paired capacities at the time of purchase )
Noctua U12A
Asus Proart X670E (November BIOS)

Anyone see anything else I'm missing in (attempted) optimisations for this setup? Or have I largely run the gamut of stuff that people will attempt to get done for a 7000 series CPU for reduced power, increased speeds, etc?

Thanks all for the look in.

Looks like a great setup.. Its a bloody pain that the memory wont run correctly when fully populated at xmp speeds, i found this out from the start, same with intel and DDR5 unless you do a ridiculous amount of testing and tweaking which isnt commercially viable and even then i think i only got stability at 4800mhz. I did have a bit more success with higher latency and the performance isnt that much difference.

Thanks @ZXSpectrum thanks for confirming that the RAM isn't going to see that much improvement if I tried to push it to higher bands of speed. Hopefully the lack of action on this thread also suggests there's little to nothing more I've missed out on trying to improve the setup given the hardware involved and what I've done already.

No problem at all. The official word from my Asus technical contact is that 4x32 ddr5 works but is only tested on the Auto settings so detects what timings and speed it can successfully train to on startup. The 4800mhz I managed to achieve stably with DDR5 was on z690 with intel 12th gen. I have settled on the auto settings on X670-P for 128Gb (4x32gb) which achieves 3600mhz with 4800Mhz IIRC. I have tried my best to get Asus to qualify some 4 Stick kits on Z690 and X670 platforms at their rated speeds but they won’t until some quad channel kits come out to which I told them that’s unlikely as both of those platforms are dual channel. I am still waiting for a couple of samples of high end z790 boards to do some testing with 128gb with 13th gen to see if the combo of the new chipset and CPUs have any better stability at close to xmp when fully populated.
