The computer fails to start after turning on AMD EXPO.
The website where I purchased this RAM kit mentions it supports AMD Expo. CMK32GX5M2B6000Z28 is the accurate product code. I apologize for any mix-up, and I will revise my previous response with the correct information. That item is compatible with AMD Expo.
To obtain these values, you need to adjust the voltage range and CL30 settings. When selecting CL30 in BIOS, it determines the subsequent parameters automatically or requires manual configuration. There isn't a single list from Corsair covering all timing options.
The values I provided are typical timing settings for CL30 RAM kits. 1.4V is the standard voltage for Corsair EXPO RAM kits, though they may differ by brand and model. If your CL30 profile exists, enabling it will automatically apply these settings. Without a profile, you’ll need to adjust them manually. In BIOS advanced mode, look for an "advanced timing" option on the AI Tweaker page—your Asus board should display it. On this page, the initial four numbers (starting with 28 if Expo is enabled) should be changed to match the ones I mentioned. If your system runs smoothly using default values and fails when EXPO is active, it means your motherboard or CPU doesn’t support the EXPO configuration of your RAM kit, requiring adjustments or a different product.
The manual indicates you may choose between an all-in-one cable for the CPU fan header or a three-connector option that lets you manage each separately. If using the latter, ensure all three connectors are connected. Some boards fail to recognize the pump header and expect a connection to the CPU fan header. You can attempt to link it to the CPU fan header instead. Confirm the CPU fan speed is set to maximum in BIOS to keep the pump operating at full capacity. Alternatively, connect the "fan" connector directly to the CPU fan header or swap the three-connector cable for a single connector and connect it to the CPU fan header.
Removing the CMOS reset doesn't erase stored profiles. Changing the firmware does, though.
