Initial Post! Recent Upgrade Issues
Budget (currency included): USA
Game setup: Wide selection of titles but focused on LLM's Stable-Diff and similar projects. Additional tasks include learning and experimentation.
Hardware: Already assembled system with X870E Elite MB, 9950X3D CPU, RTX 5090 Aorus Master, 128GB T-Create 6000MT/s RAM, Samsung 990 Pro NVME 2TB drive.
Issues encountered:
- During BIOS setup, EXPO was activated and AI adjusted RAM settings. Options appeared at 6000MT/s and 6200MT/s; selected 6000.
- System started normally after reboot, but BIOS showed EXPO disabled and RAM set to 3600MT/s.
- After re-enabling EXPO, it automatically turned off again.
- Manually set RAM speed to 6000MT/s, but PC failed to boot.
- Moved SSD to Gen4 PCIe slot in hopes of using all lanes for RAM. Removed two RAM modules as per Gigabyte’s advice.
- Re-enabled EXPO, now reported 4800MT/s and booted successfully.
Concerns:
- Current RAM is XMP/EXPO rated; unclear why EXPO reduced speed.
- XMP works on AMD systems despite being uncommon for BIOS.
- If T-Create fails, consider using a 64GB module to reach 128GB total.
- Questions about maximum achievable speed with all four slots and why XMP succeeds while EXPO doesn’t.
Advice:
- Test RAM speeds with all four slots; monitor stability.
- Verify BIOS version and ensure it supports higher speeds.
- If T-Create remains non-functional, explore alternative configurations or upgrades.
The 4 DDR5 RAM sticks at 6000 MHz might put a lot of strain on the memory controller. Are these sticks officially tested by the motherboard manufacturer? Updating the BIOS to the latest version could improve compatibility. Still, you’ll likely need to experiment a bit before finding a stable speed. This isn’t just about starting up—it’s about smooth operation without crashes or strange behavior caused by a stressed memory controller.
Consider reducing the RAM clock speeds. 6000MT/s seems quite high for four modules. Or, take out two modules and use them in dual-channel configuration.
Both Crucial and Kingston offer 2x64GB kits. The link provided indicates compatibility with the motherboard.
Here’s a summary of your recent efforts and next steps:
I’ve optimized the RAM settings to maintain a stable 5600MHz. The CL40-40-40-78 configuration hasn’t been adjusted yet, but I’m satisfied with the current performance. For a potential upgrade, I’ll be searching for a 128GB (2x64GB) deal during Black Friday.
