Is it possible to benchmark a single RAM stick

[shatter0000]

Asus GL502VM and 8GB memory soldered are what I am having now. For few necessary reason, I"ve just installed 8GB more, but some of the benchmark were lower when installed. I can't understand if it is possible to benchmark only the new RAM stick...
Thank you so much!!

No, it isn't possible if the rest of the RAM is soldered in.
