It looks like you're dealing with some RAM that operates at 1333MHz with timings of 9-9-9-24 and runs at 1.5V. If you're considering changing the command rate from 1T to 2T, it could potentially improve stability, especially if you're pushing the RAM to its limits or if the memory controller is having trouble with tighter timings.
Given that the RAM chips are 30nm ( they should indeed run cooler compared to older, higher-nm technology. Adjusting the command rate to 2T can sometimes help with stability issues, particularly when overclocking or running the RAM at higher speeds.
Make sure to monitor system stability and performance after making these changes. If you encounter any issues, you might want to test different settings or check for BIOS updates that could improve memory compatibility and performance.
