Hi
@tibcsi0407, thank you very much!
I will take some settings of your BIOS config and I'm going to try again with RONs 48-40/40-48. I'm still trying to find the VDDQ-TX Sweet Spot, It's not easy.
Are you running MRC Fastbook and Fast Boot enabled? That seemed strange to me. How do you achieve stability in retraining? For me in version 0080, with MRC and fast boot disabled it seems even very fast. Sometimes I try the ASUS Training Mode which makes it slower...
Something I haven't been able to discover yet is the value of VDDQ for VDDQCPU. On the other hand, having a similar processor and mobo, the only difference being the memories, which in my case are A-Die XMP 8000 at 1.45, I cannot understand why VDDQ_Mem is so low in the M-die kits that I see, and why they operate with such a low SA. I don't think it's the mems. But it never ceases to surprise me, because I always thought that APEX OG allowed very low SA values, but not in Encore. Now I managed to lower the 1.2, but I can't stabilize it. I have a lot of work ahead of me.
What I'm going to do is start with the V/F Curve first. Here I see the double S in Luke Joseph's post, BTW,
@LukeJoseph thank you for sharing all the points of your VF Curve, I'm going to copy them as is so it automatically calculates my offsets. With my factory V/F values, I cannot pass CB15 Extreme or CB24, or YC SFT.
My first diagnosis is that for such demanding workloads, without an undervolt, I cannot withstand the transient spikes, for example, when I change from VST to VT3, there is a jump in temperatures, so I am running VST with 313W at 90C, and When changing to VT3 the power package it goes to 96 and then VT3 stabilizes at 86 and goes up. Then when shifting in another transition, it goes to 97 degrees and fails. I'm sure my VF curve has a lot to do with it, since it starts at 730 but then drops to less than 700 at 1400MHz, and goes up fine from there.
Thanks
