Hi,
I have x870e hero and KF564C32BBEK2-64. Expo 1 and 2 doesn't work. Only Expo on the fly works.
Shud I change KF564C32BBEK2-64 to KF564C32BBEAK2-64? This is practically the same, some have backlighting, some don't.
I have latest bios. What should I do?
Thank you very much

Maybe this is bios error? Like here https://youtu.be/H8FdNK10H2w

Hi @piotrl
KF564C32BBEAK2-64 is actually validated by the memory vendor for AMD platforms. Different platforms have different voltage guardbands, and as a result the XMP/EXPO profiles may require additional tuning.
Have you tried increasing VDD/VDDQ 30 to 40mV?
