B450 Tomahawk Max RAM issue XPM
Hey there, I own a B450 max tomahawk mobo with Corsair 2x8GB RAM at 3200 MHz. I faced an issue and had to flash the latest BIOS update before that, and before that I cleared the CMOS. Before this, my RAM was set to profile 2, but after the new BIOS flash, none of it worked at 3200 MHz. I've tried profile 1 and both profiles with manual settings at 3200 MHz, but nothing helped. Any advice?
Current BIOS version for your motherboard is unknown, and the specific RAM slots being populated are not provided.
Did you reinitialize the CMOS after updating the BIOS? Try doing it by disconnecting the power while holding the battery. One thing I've noticed is that the BIOS sometimes fails to establish the required XMP voltage. Adjusting the RAM voltage manually can be quite useful. Also, could you tell me what CPU model you're using?
I have a Ryzen 5 2600 with CMK16GX4M2E3200C16 and a BIOS version 7C02v3F, with the RAM stick located in the second slot and the next one.
The Ryzen 2000 series CPUs are designed for 2933 RAM speed, though they can reach 3200 occasionally. However, consistent performance at higher speeds often requires more than just enabling XMP; some adjustments are needed based on the specific system and RAM modules used. The 3000 and 5000 series CPUs, with their enhanced MMU, reliably support speeds up to 3600.
So...you understand it's possible. Just make a few adjustments.
A newer BIOS might introduce new initialization settings that clash with your memory module, if you prefer revert to the previous version and skip the changes. The main reason to update the BIOS is to ensure compatibility with a future CPU or to resolve an issue you're aware of.
I wouldn't say it's mandatory, but it's a possibility. A solid choice if you're sure your memory will function properly.
A key advantage of the newest BIOS is improved compatibility with Windows 11. This typically means UEFI support and potentially TPM functionality are enabled by default; you can manage these settings as needed. You might also forgo Smart Access Memory without the latest BIOS, but it's likely not essential unless you plan to upgrade your CPU.
