It is my understanding that you can only run one voltage at a time for all memory/slots, if this is correct, you are probably running the lowest voltage (1.35V) on both slots and the slowest timing on both chips. Meaning that your faster memory is running at the slower speed.

If you run the MemTest86+ for eight passes without failure, then I 'd say you'll be fine. But you still won't be getting the best performance out of your memory.
1600mhz running as 1333 MHz , right ? the ram 1600mhz voltage is the lowest (1.35v)
ill run MemTest86+ for eight passes, if it passed fine wont i have blue screen or damage cpu or motherboard or ram?

There are no guarantees.
Memtest is a great testing tool but it does have it's limits. It will test that all registers can perform without error.

Voltage problems with RAM can affect other components of the motherboard and/or processor. These would be problems with the memory controller and with the voltage regulation system.

If the RAM modules can and will run at just one voltage (1.35v) without errors then you will probably not have any of the other problems with the motherboard.
If the faster RAM complains about the lower voltage you will get errors in Memtest.
If either stick of RAM will not play nice with the other then it is likely you will see crashes, glitches, and weird problems.

Whether you meant to do it or not, you are conducting an experiment there.
Please let us know the results!

the memtest test passed fine, If I didn't have a problem after 1 day, wont the difference of the voltage be a problem ?

If Memtest86+ passed 8 times through, and you are not getting any blue screen crashes, then I'd say you are good to go.

Ditto about CPUZ report. What does HWinfo64 have to say about the voltages? This will show the "running" volts.

I'm nursing a sprained wrist so typing is limited by the pain and the wrist support.

when I ll know the RAM modules can and will run at just one voltage (1.35v) without errors ?
I installed HWiNFO64 it show me a thing maybe can explain why they run both together even the difference of the voltage , look at the voltage !

Does it mean it can run at 1.50v or 1.35v ?

Apparently so. First one I've seen like that. What does the Sensor screen show for memory voltage?

Sorry I don't know which Sensor screen you are talking about ?

Normally you get four screen panels when you start HWinfo. The main screen, a system summary, CPU graph and the Sensor panel. (Outlined in Yellow.) The sensor panel shows usage, temperature, voltages and fan speeds. (Along with others.)

but why Cup-Z and Speccy didn't show 1.50v with 1.35v ? they only show 1.35v


I looked up by the Module Part Number and I found this

ok, sounds like a stupid question, i know, but if i purchase them by ende of tomarrow i get 25% off, and i plan on upgrading mobo soon. i have been generaly informed on another post that 1600 in 1333 should work, it will just operate at 1333 speed, is it the same with 2133?
