Can I use 1066 and 1333 Ram together?
No, the correct answer is that it does not matter.
You can mix RAM of both speeds (1066/1333).
The system will automatically use the slower speed, but there is no risk of system crashes.
And no, 1333MHz RAM will not be recognized in a 2009 iMac, but 1066MHz in the 2010 is just fine..
Is it OK to mix and match RAM?
Can you mix RAM size? Yes. But it might not be best for performance. It is advisable to use RAM sticks by the same manufacturer, of the same size, and of the same frequency.
Is there a big difference between 1333 and 1600 Ram?
The 1333 and 1600 designations refer to the transfer rates – theoretically, given same CAS latency, DDR3-1600 would perform better than DDR3-1333 due to its greater maximum bandwidth.
Can 2 different RAM work together?
As long as the types of Ram you mix are the same FORM FACTOR (DDR2, DDR3, etc) and voltage, you can use them together. … It used to be only the Form Factor that was important, but with low voltage Ram now on the market, that has to be taken into account as well. So yes. Different brands of Ram are fine to use together.
Can I put 1600mhz ram in a 1066MHz slot?
Yes , but RAM speed will be only 1333mhz at max if it is only the one stick being used . … both RAMs will run at same speed. If ur first RAM is operating at max 1066mhz then no matter what ,your new RAM will also run at 1066 And the rest of the story anyone can understand of course.
Is 1066 MHz RAM good?
DDR4 memory is newer standard utilizing higher frequency memory. Higher frequency means faster access rate. So 2400Mz is faster than 1066MHz but in real world scenario 8GB is better due to higher capacity over 4GB. Consider this analogy, 8GB DDR3 as a 5 seat sedan & 4GB DDR4 as 2 seat sports car.
