RAM upgrade -- is something wrong?

[tussin33]

hey guys i recently just bought a 2GB stick of ram because the price was right. Im at 8 GB now and its not the same brand and etc as the other 3 that came with the PC i hear that this can cause issues and make it slower then before... soo i took a pic using CPU-z to compare the frequency's . The one on the left is with the new Chip, the one on the right is without.. as you can see there are 2 Numbers that are different, is this a cause for concern? or should everything work smoothly?

The numbers are hard to see, even when zooming in on the image.

I couldn't tell which value was different.

sorry about that, photobucket sucks like that.

the new RAM's Command rate 2 T compared to my other 3's 1T

also the bank cycle time (tRC) is 34 clocks while the other 3's are at 33 clocks.
