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.
