    What heat are you referring to? You will see no more or no less heat based on your memory setup.
    If you are concerned about heat overall you can add an app to monitor the temperatures of your system (many BIOS screens will show MB temps too). A lot of people like this one Core Temp
    Another is HWMonitor (from the same group that provided the CPU-Z that your using) HWMONITOR | Softwares | CPUID

    I was talking about heat of the processor / motherboard .

    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 ?

    Most of RAM modules can and do run at higher voltages, mine is running at 1.67v to be able to OC to 1600MHz without a hint of overheating. There's no temperature reading for them anyway. Only in case of overclocking RAM past the speed of memory controller in the CPU, you may see some temp increase in the processor.

    Voltage those RAM sticks are supposed to run at.

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

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

    Because both work at the speed and settings (including voltage) of slower one. MB and BIOS can't provide different voltages for each bus. It's best to have all memory modules same and paired to get best compatibility and full performance. It also happens that two different RAM modules do not want to cooperate at all depending also of how BIOS handles it and if higher module can work at lower voltage.

    you mean even the slower RAM wont run at the top performance ?
    I don't care about RAM 1600 MHz works at 1333 MHz, because my old one is 1333 MHz and the seller gave it to me the same price as 1333 mhz.

    No, slower RAM and the faster one will run at the speed and settings of slower one, that's all. You are right about not caring about that difference in speed because it would amount to less than 1% of total computer performance. It's better to have more RAM than faster RAM if one has to choose.

My Monitor has been showing stretched-out images lately. I knew that my screen resolution is not right. I tried to change the screen resolution but there were only two options (1024 X 768 & 1280 X 1024) but none worked. It is my old monitor so I know that the correct resolution is 1600 X 900. Then...
