Hey guy's after thorougly trying out what my memory kit can do in terms of better timings at 6000MT/s I figured out this is what I can achieve at the moment which I would consider stable at the moment. I am not quietly sure how actually good this is or if these timings do even make sense?
These are my related hardware:
Ryzen 7 7800X3D
ASUS ROG Strix B650-A Gaming Wifi running Firmware 3842 for this board.
I am using a Corsair Vengance kit with 6000MT/s and CL30-36-36-76 @ 1.4V version 5.43.13. What I could find out is that these sticks are using the SK Hynix A-Die chips? But I am not sure, would be nice to know how I could determine which hynix dies are on these sticks actually.
OS: CachOS (that's why I made pictures of my memory timings and settings in the BIOS/UEFI, because on linux as far as I know has no dedicated tool to read out the spd informations?)
I don't know why but I am heavily struggling on lowering the TRCD and TRP main timings although I could get TRC and TRAS lowered to 28 simultanously. I did try to lower TRCD to 34 which occasionally might boot but it wasn't stable. I also tried to only lower TRP further from 34 to 32 and leave TRCD at 36 which I could unreliably get to boot but with 1.5V for the DRAM VDD/VDDQ and CPU VDDIO / MC Voltage and 1.3V for the SoC voltage. Which didn't make any sense to try further because these voltage ranges in my oppinion are definitely to risky as a 24/7 setting. I believe this shows me that I either got a bad board, CPU (memory controller in the cpu) or just a bad memory kit? I am honestly clueless at this point
I tested these settings in OCCT for 1 hour only memory testing with 90% load on the memory and AVX2 on the instruction set. These timings passed the stability test without any issue in OCCT and no system crash. The reason for not doing a longer stability test like 4,6 or 12 hours is that I actually wanted to test what is in general possible with my setup and tweak the timings to the point until the system won't POST or be stable enough to POST correctly. This was my strategy until now
I hope you have some advice on what I could improve next and I hope someone could tell me if these memory sticks are actually using hynix a-die chips based on the SPD information of my motherboard. I appreciate any tips and thanks in advance 🙂
