I only had 2 rock stable overclocks one for 3733 mhz and one for 3800mhz cl 16. U might find my earlier posts about those. Whenever I tried to improve my timings even a little bit, it failed at some point and with the 2.73 Bios even my rock stable overclocks went bad. I have finally discovered that this was happening because of the voltage settings for CPU VDDCR_SOC. I have seen that many of you and many of the tech utubers had it set at 1.1 with LLC 2 so I was doing the same. It seems that it was completely wrecking my otherwise good overclocks. I have finally passed 1000% in memtest with it on Auto. Will see how much will I be able to improve my current overclock.
First off, and of the utmost importance, import your ram info into Ryzen Dram calculator from Typhoon Burner, the small variances between the two can make a world of difference.
Also, in Ryzen Dram calculator, try and do as many of the advanced settings you can find in the bios, and this again can make a world of difference.
The bios does a good job of feeding proper voltages to the SOC, etc. on auto, however, you will always need to supply more dram voltage to get tighter timings.
3800 cl16 is a sweet spot, and i bet your best performance is here.
