This is the first time I've seen a VDDQ higher than VDD on these Arrow Lake HX systems.

These are the settings I used with my old Neo 17 with I9-13900HX probably not ideal for Arrow Lake but worked.

Still looking to get the voltages right for 7200MT/s but nothing is sticking and it restarts to 4800MT/s. Will keep upping the votages. 

Appears stable at 7000MT/s; VDD 1225, VDDQ 1175, & VPP 1800 with the standard 6400MT/s XMP timings.

A good settings for your memory, I believe without much difficulty, would be 7200 CL36 with:

 

tRCD/tRP = 42 or 44

tRAS = 60 to 84

 

VDD = 1275 to 1325

VDDQ = 1225 to 1275

 

You can also set the tREFI to 16-32k.

 

Once you find stability, you can adjust the subtimings by researching and understanding each step.

 

AI can help!

Perhaps because tRCD/tRP = 40 is too tight for 7200MT/s.

New TimeSpy high score for me.

RAM at 7000MT/s:

tCL : 36 

tRCD/tRP : 42 

tRAS : 72 

tCWL : 34 

tFAW : 24 

tREFI : 30000 

tRFC : 560 

tRRD : 4 

tRTP : 12 

tWR : 48 

tWTR : 14 

tRFCpb : 300 

tRFC2 : 400 

tRFC4 : 300 

tRRD_L : 12 

tRRD_S : 6 

tWTR_L : 24 

tCCD_L : ? 

tCCD_L_WR : 64 

tWTR_S : ? 

NMode : 2? 

 

VDD : 1250 

VDDQ : 1250 

VPP : 1825 

The 2 timings with ? will automatically crash if changed. 

Any other suggestions for tightening timings/increasing voltage?

I have two sets of memory, both 2x32GB dual-rank, so it's quite different (and demanding) compared to your kit.

 

If your memory is Hynix A-die, you can probably lower the tRFC significantly (384-448).

Try making it the same as tRFC2.

 

tRAS also, you can probably reduce it quite a bit (42-54).

 

You should be able to achieve 7200MT/s by increasing the VDD to 1300.

It may be necessary to loosen the tRCD/tRP slightly to 44.

 

For everything else, it's difficult for me to comment...

 

I went back to using the original memory, Adata 5600MT/s CL46, because its adjustment limit is almost identical to the other set I have (Fury Impact 5600MT/s CL40), both are Hynix A-die.

 

With Fury I can get some slightly tighter subtimings, but without a relevant difference in performance.

Perhaps 200 to 300 more points in the CPU score on TS.

 

Without access to manually adjusting SA and VDD2, I can't go any further...

 

My tuning is:

 

RATIO 192        
tCL 36
tRCD/tRP 39
tRAS 54
tCWL 34 (32 with Fury)
tFAW 16
tREFI 24576
tRFC 400
tRRD 0
tRTP 20
tWR 72
tWTR 0
tRFCpb 320
tRFC2 400
tRFC4 0
tRRD_L 8
tRRD_S 4
tWTR_L 24
tCCD_L 14 (12 with Fury)
TCCD_L_WR 64 (56 with Fury)
tWTR_S 7

NMode 2
VDD 1300
VDDQ 1250
VPP 1800
