Check if MSI PRO 22XT 10M allows access to additional BIOS settings.
Got a MSI PRO 22XT 10M 016US recently, a modest Pentium G6400 build with a low price tag. I was aiming to unlock BIOS settings such as memory speed, timings, and voltage controls—without jumping into overclocking. I planned to swap in an i3 or i5 CPU, add more RAM, and optimize its speed and timing for better overall performance. The idea was to tweak BIOS options to squeeze out a bit more from the processor and graphics card. I attempted using the ctr+alt+shift+f2 shortcut on MSI laptops, but it didn’t help. I’m not sure what else to try before diving into BIOS edits. I saved a BIOS file, but when opening it with AMIBCP 5.02 or AMIBCP 4.55, I encountered errors about string limits and language length—making it hard to access the setup tabs. Those issues seem out of my reach right now. My main goal is just to have some memory configuration options in BIOS. Where should I look for help? Maybe someone willing to pay a few dollars for assistance?
The bios remains protected; changes aren't allowed, but experimentation is possible.
It seems AMI EFI bios are actually getting more modified lately. I also got the UBU but it looks like I can only tweak the CPU microcode, VGA BIOS, and a few other settings I don’t want to alter. 2T timings are terrible and 2666 feels sluggish with C19. Disappointing.
You search for AMI BIOS editing tips and find many options for modifying AMI EFI firmware. Be aware that newer Nvidia BIOS versions, especially the 10 series and beyond, are restricted.
The bios settings exist for activation. If they aren’t present, you can create them from the ground up.
The system is using 2666 C19 memory. It seems to be running at 2666 with its current timing settings. Checking BIOS or CPU data confirms this. If you replace it with a different module, it should maintain 2666 unless timings change. No need to worry about prebuilt systems—this setup is stable as long as the RAM matches the specs.
Most of the Sodimm is built with redundancy and stability in mind rather than peak performance. Finding a model with a CAS latency around 16 or lower at 2667MHz will be challenging. Even among high-end desktop DDR4 options, memory speeds below 2667MHz typically offer less precise timing than XMP profiles. The best way to improve performance here is by optimizing the operating system—perhaps using a lightweight version like W10 Lite or Linux. Hardware limitations are now more pronounced; software tweaks usually don’t help unless you can adjust timings dynamically, which isn’t practical. It’s no longer possible to simply “get lucky” with memory settings. The design of this hardware is fixed—no software can significantly boost it without altering core components. Writing a custom BIOS from scratch would be necessary for such a setup. If you’re open to it, BiosMods might have relevant work in progress; you could also reach out to them directly. Flashing a custom BIOS is the most reliable path, and having two identical systems helps with testing and verification. For reference, CL19 latency is considered optimal for 2667MHz memory, as seen in a 4267MHz memory example with a 2133MHz Jedec. At 1066MHz, the CL drops to 16.
I placed an order for 3200 C22 RAM with 3200 C22 timings in SPD configuration. It can also run at 3200 C16 at 1.35 volts, which is interesting. In the worst scenario, I might have four times the memory active in dual channel at a lower speed of 2666 C19, but I still expect double the bandwidth and four times the capacity for $60. This doesn’t seem like a disadvantage, so it works out. Looking inside it feels solid—well-assembled with a good 3 heat pipe cooler, a blower fan, and decent fins. An i3 or i5 should fit easily even with higher power limits, and it’s easy to open up for maintenance. Closing it back up with more RAM alone doesn’t seem problematic right now.
RAM arrived, was set up, and the system started. It’s 2666 CL22 but with dual channels—totally impressive! Performance is noticeably faster, and it runs smoother overall. The G6400 feels much more stable now, no more lag or stuttering compared to before.
