Hello everyone,
I would like to ask for your advice.
A few months ago, I built a high-end gaming PC, and I am now trying to fine-tune / overclock my RAM. However, I have run into stability issues and I’m currently unsure about the exact cause.
Issue:
While playing CS2, I occasionally experience crashes with a Pak001 error. From my research, this can be related to unstable RAM settings, such as voltage, sub-timings, or overall memory controller stability.
In addition, I also have a second, unusual issue:
Sometimes only one of my two monitors is detected or receives a signal. After fully powering down the system and waiting a short time (to discharge residual power), both displays work normally again after reboot.
System specs:
* CPU: Intel i9-14900K
* Motherboard: ASUS Maximus Z690 Hero (BIOS 4505, latest)
* RAM: Corsair Dominator Titanium 32 GB (6000 MHz CL30, XMP enabled)
* GPU: Gigabyte Aorus Master 5070 Ti OC
* PSU: ROG Strix 1000W Gold Aura Edition
* SSD: Samsung 990 Pro 2 TB
* Cooling: Corsair iCUE H150i Elite Capellix XT
* Fans: 6× Corsair LX120 RGB
My assumption:
I suspect instability related to memory tuning, possibly involving IMC stability or memory voltages/timings (VDD / VDDQ / System Agent, secondary and tertiary timings).
Question:
Is there anyone here with solid experience in DDR5 overclocking (especially Intel 14th gen / Z690 platforms) who can help evaluate this setup?
I am aware that RAM overclocking can quickly lead to instability, especially when adjusting voltages and sub-timings. That’s why I want to avoid random trial-and-error and instead aim for a stable and properly tuned baseline configuration.
Thanks in advance for any help.
