My HP Elitebook 745 G5 has two SODIMM RAM slots feeding it's dual channel memory controller.
It takes 2400MHz DDR4 sticks.
Apparently there is a performance increase for either Single or Dual Rank SODIMMs.
I'm not sure which one is faster though, Single or Dual.
Can anybody explain which is faster and why?
Here are links to my choices:
Crucial 16GB Kit (2 x 8GB) DDR4-2400 SODIMM (Single Ranked)
Crucial 16GB Kit (2 x 8GB) DDR4-2400 SODIMM (Dual Ranked)
Crucial 32GB Kit (2 x 16GB) DDR4-2400 SODIMM (Dual Ranked)
32GB is not available in Single Ranked.
I will buy the fastest, followed by whatever's the largest.
The RAM controller is limited to 2400MHZ, but they also sell 2666MHz sticks. They won't run at 2666MHz, but I was wondering, if I bought 2666MHz SODIMMs and it runs them at 2400MHz, would I be able to reduce the RAS/CAS timings? That used to work back in the day, but I haven't built a PC since the DDR2 days!
Yeah, I found conflicting answer through Google. Although most of the responses agree with yours and the links you posted. – RoboJ1M – 2018-12-05T10:19:48.913
