Question Can a mobo go from 2 DPC to 1 DPC through the BIOS ?

[kranebrain]

I'm learning about DDR5 memory on Intel processors and how having 2 DIMMs per channel will slow the memory frequency. If there's a motherboard / PC with 128GB (4x32GB), can 3 sticks be removed to leave a single stick in to get 1DPC speeds? If not, can bios be changed to have the motherboard treat it like 1 DPC?


I hope I'm making sense.

DDR5 memory has dual channel mode on each stick of ram that is where the confusion starts. You are running in quad channel mode really using two sticks of DDR5 ram. However, Intel still considers it dual channel mode.If you use only one stick of ram you will be in single channel mode, if you use 2 sticks of ram you will be in 2 channel mode, If you use 4 sticks depending on the motherboard and cpu used, you will be in either 2 channel mode (usually at a reduced memory speed) or quad channel mode.

So I assume you're saying quad because each stick is 2R? How is that different than 1DPC @ 2R?

What would 4 1R sticks be considered? Or 2 1R sticks?

I know the CPU has 2 channels, so is there a way to get this computer, which current is in quad at reduced speed, to 2R 1DPC speeds?

Thank you very much.

The channel just means how many ram slots are populated by ram sticks. DDR4 would be 1 stick, single channel, 2 sticks dual channel, in motherboards with certain cpu's you could either have 4 sticks in dual channel or quad channel if supported.
