Compatibility for another set of PVV34G1600LLK

[Allo]

G'Day.
I bought a set of Sector 5 PVV34G1600LLK (2x2 Gig) awhile ago and have been happy with them so I would like to get another set. I went searching for a matching pair and have found some very, very similar products but with some slight differences.

My set......
PVV34G1600LLK
8-8-8-24 (this is written on the back of the RAM)
DDR3 1600Mhz
1.65V

All the other sets I've looked at.....
PVV34G1600LLKB (An extra B on the end)
8-9-8-24 (Mine is 8-8-8-24)
DDR3 1600Mhz
1.65V

They look like the same packaging and both come with the free 3D Mark.
Just trying to confirm that they will work together and one won't slow down the other.
Any help would be appreciated.

We changed the specs basically because of a chip supply issue. Furthermore yes, they should work together. However, please keep in mind that we can only guarantee the rated speeds obtainable per kit. When adding the additional kit, it may further stress the memory controller and you may need to relax the timings and/or frequency.

I keep all things stock.
So are you saying I'm good to go?
Or are you saying I will have to alter things in the bios even at stock settings?

[Allo]

Never mind. I think I understand what your saying.
I checked the speeds my current RAM is running at and they are running well below what they can run at so I bought the other set of Sector 5 RAM.
Thanks.
