In reply to Edu.

the first ram that i tried (1600 Mhz) is indeed a single rank module.

how do you know that motherboard works only with dual rank ram ?
where is that information found ? i could not find anything in the specs online.

You are wrong in your conclusions, the reason some rams work and other not is not the speed, 1600mhz ram will always work on a 1066mhz motherboard.
The thing is you motherboard need 2rx8 ram modules instead of 1rx8.
The first model you posted that didn’t work is 1rx8, the second one is 2rx8.
Basically this menas the module must have chips on both sides (2rx8) instead of only one side (1rx8).
That’s all

Hey bro… thank you so much for the information. Just a query
My old all in one pc from hp purchased in 2012 has a ddr3 2gb ram (1067 speed) with intel celeron 1.6ghz or 1600 ghz. Can I upgrade it to 2 x 4 ddr3 ram of 1333ghz? By the way my windows has already come to an end of life so even new updates are not taking place anymore.
If try to update, the system first initializes then downloads and finally freezes forcing me to shut down the power switch. By the time I reopen my system “undoing changes made to your system” apears.

Thanks for the article bro.. loved reading it and was actually looking for some article like this one. I just recently happened to upgrade RAM in my HP laptop.
The upgrade was inserting an additional memory in the unused 2nd RAM slot. Inserting a higher frequency ram to a lower frequency slot, that was on my 7 year old HP Sleekbook 14 which has a 2nd gen core i-3, supporting only 1333Mhz. The 1st slot already had a 4-GB 1333Mhz DDR3L stick installed since beginning while I plugged in an additional 4-GB 1600Mhz DDR3L (of Silicon Power brand). The higher frequency 1600 ram downclocked to 1333 and is working fine. The command prompt window shows both the RAMs at 1333 Mhz speed. Also read the service manual, which reads as “DDR3-1333 MHz support (DDR3-1600/DDR3L-1600 downgrade to DDR3-1333), for use with computer models with 2ndGeneration Intel Core, Pentium, or Celeron processors”
