Different voltage memory modules

Question regarding upgrading my RAM.
Originally I built my system with 2x2GB 1600MHz CAS 8-8-8-24 1.35V DDR3 GSkill modules. Like these, just CL8:

Recently I purchased another set of GSkill memory, this time 2x4GB 1600MHz CAS 8-8-8-24 1.5V DDR3. This one:

My question: is it OK to mix these two on my motherboard or am I better of just using the newer set?

Thx for any help!

It should work fine, although sometimes it doesn't, but mostly it does.

Its not recommended by the mobo makers, but mobos are flexible.

Link to first memory says CAS9 at 1.35 volts. That means that at 1.50 volts, there is a really good chance that at 1.50 volts, they will run at CAS8.

Running both sets at 1.50 volts and CAS8 should work.

So there is no chance that I'll end up frying anything (mobo, RAM, processor)?

OK, I'll give it a shot :)

Not with that, just watch out for the static electricity build up in your hands!

Touch the case metal frame before u touch the RAM.
