Re: OT: UEFI settings for DDR5 RAM

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



I recently upgraded to an AM5 system with 128gb ddr5 memory.  The lower 4800 is the base frequency.  The 5200 might be if you overclocked it.

It appears to be using an A-XMP profile (according to the screenshot I

posted). I just wonder why it says it's at 4800 instead of 5200.

 

Google didn't provide anything immediately useful but for AM4 systems and XMP profiles you want the memory frequency to be an even multiple of the CPU bus frequency. Check the CPU page in the BIOS and see if that's the case. It may be the ideal frequency for your processor.

 

Thanks,
