Hello
I currently have Adata XPG v1 with 1600speed cl11 at 1.5v 2x4 modules.
My local store has a excellent deal on Kingston Hyperx Predator which is 2x4 1600 cl 9 at 1.65
Is it possible to run both pairs of ram together to achieve 16gb?
Should I overclock the adata to 1600 cl9 with 1.65v or downgrade both to 1333 cl9 at 1.5v?
Is it recommanded doing so?
My specs are GB Z87-Ud3H, I3 4330(upgrade soon), and 750Antec HCG
Thanks and have a happy new year?

The one to choose, if you do choose only one pair, is the Kingston. The voltage that the RAM runs is separate from the voltage the CPU runs and should not damage each other. That being said, I believe on that generation of Intel chips the rating for the RAM is 1.5v, its your call ultimately.

Alternatively, you could buy the RAM and resell it if its such a good deal, surely you will make a profit.

I wouldn't mix the two. The ADATA uses 1.5V, whereas the Kingston at 1.65V.

It's never a good idea to mix different brand modules, especially when the specs vary this much.

Is there a reason why you're buying more RAM if you have 8GB already?

True, I dont think anyone actually needs 16gb. 8gb is more than enough!

Alright, The kingstons are 75% off in my local dealer store, Would bang my head against a wall if i missed a deal like that.
If I would go with one of the brand for only 8g, which one is better?
Also, wouldnt the 1.65v on the kingston damage my CPU? (read that somewhere..)

The motherboard should automatically run all memory at the same speeds, which is only as fast as the slowest module (the Adata in your case). If you install the RAM and load your operating system:
Will it run and recognize all 16GB? Probably.
Will it be stable? likely.

If you try to overclock you will run into the same limitations all overclockers face, instability and performance limitations, these will be amplified by not having matching RAM. Overclocking is always a risk/reward system where you run the risk of system crashes or hardware malfunction in exchange for possible performance increases, as a result I don't like recommending overclocking a system simply because I don't want any blame coming my way.

Hope that gives you a start.
