The dual channel is quicker than a single fast channel in this situation.
The dual channel is quicker than a single fast channel in this situation.
You're considering how to upgrade your system. You bought a laptop with DDR4 3200 MHz RAM but it only has two slots, and you have matching DIMMs. The new PC has only two slots, one with DDR4 2400 MHz. You're thinking about mixing the 3200 MHz sticks with the 2400 MHz ones or swapping the 3200 for the 2400. Which option would give better performance?
3200 plus 2400 matches 2400 plus 2400 because they run under identical configurations. Each will perform better than using just one channel, as 3200 is less than 2400 doubled.
If you own the dimmer switches, why not try them out yourself? However, using two slower ones might improve performance in a dual-channel setup for many applications.
However, one 2400 MHz chip would only reach 1200 MHz, you should use two to achieve at least that frequency. I was told this before, and 3200 MHz would actually be around 1600 MHz in a single channel. Single channel 2400 is higher than 1600 MHz.
