I have installed a new RAM in my laptop and want to compare performance of individual RAM's. Is there any tool that allows me to test speed of individual RAM's.
You can use Memtest86+:
Note that if you have 1 RAM at 1333 and 1 RAM at 1600, it would just run at 1333: RAM will always run at the speed of the slowest stick. Same for the latency: the highest latency will be used by both RAM sticks. As a result the only way to compare individual RAM is to manually add/remove them from your computer and run a speed test on each of them.
