Hi first time poster to this sub.
I've dabbled with overclocking on my previous rigs but I've never run into this much hassle before.
My current rig:
CPU: Intel Core i7-12700K
CPU Cooler: Noctua NH-D15 with dual 140mm fans
GPU: NVIDIA RTX 4070 Ti Super
RAM: Corsair Vengeance DDR5 5200MHz 32GB (2x16GB) CL40, XMP 3.0
Storage: Kingston KC3000 M.2 2280 NVMe SSD 1TB
Motherboard: ASUS ROG STRIX B660-F GAMING WIFI
Power Supply: EVGA GQ 750W 80 Plus Gold
I've tried XMP profiles to no avail and thus disabled it and gone the manual route.
I have tried setting it to both 4800 MHz and 5200 MHz with the settings below:
CAS Latency (CL): 40
tRCD: 40
tRP: 40
tRAS: 77
DRAM VDD: Set to 1.25V.
DRAM VDDQ: Set to 1.25V.
Also tried setting both VDD and VDDQ to 1.1 for 4800 MHz.
All of it results in bootlooping and I am now at my wits end.
Please help this poor soul out!

Added a photo of one of the ram sticks Incase that can help identify the issue and maybe someone will be able to tell me what Micron die is used in the sticks.

Make sure you’re looking at the right clock speed lol. The base speed should be 4800mhz but some RAM speed displays only show you the Memory Clock which is half of the rated speed, which then gets doubled (DDR=Double data rate).
Also, the RAM-associated voltages should be between 1.25 and 1.35 volts. If you’re experiencing instability, increase the voltage.
I could be mistaken but I think VDDQ has to be higher than VDD, or maybe it’s the other way around.
