Windows 7 - Random Acess Memory Issue

Hello everyone,
Today i bought more one RAM with the same mark, same megahertz's, and both of them with 2 GB's, but the RAM model's are different.
I'm going to post the link with info of the last one i bought.

The name of the old RAM it's KVR2GBDDR3133 Kingston DDR3 2048MB 1333Mhz, but i don't find any website with info.
My question about this is, this may create any conflict due to different RAM model's?

As long as the timings, type and speed are matched, you should be alright using those modules. Just check them both for their CL number and their speeds (DDR3 1333, etc.) and you should be ok to run stabily. However, this is from my own personal experience - your situation may vary.

Hello NeroDevil,
I'm not certain of the model of the first one i have bough and i dont have how to check it, but i think it's this one.

The only difference between them it's the sequence number, one is "KVR1333D3N9/1G" and the other "KVR1333D3N9/2G", and if this is correct, the Mhz, CL and V are the same.

Grateffuly,
