Question Upgraded RAM showing on CPUz but not in Task Manager and BIOS

Dear All,

I am quite puzzled as i upgraded a new RAM in my laptop and its not detecting. The laptop mother board supports upto 16 GB of RAM. It has preinstalled 4 GB of DDR-3 RAM. I tried to upgrade RAM and inserted 2 GB into the other slot.
After installation and restarting, i was not able to see the upgraded memory in task manager.
I tried reinstalling it to confirm that its fitted properly and then checked using CPUz.
I was shocked to see that CPUz is reading all the installed RAMs in both slots while task manager is not reading the additional 2 GB Ram. Even BIOS is not showing the additional memory installed in Slot 2.

I am attaching the screenshots of the above for better understanding of this problem.
Total Memory CPUz :


Slot 1 CPUz :



Slot 2 CPUz :



Task Manager (Windows-10) :



Please help and suggest me the solutions. I am using Windows 10 Operating System and already updated with latest BIOS.
Thanks and Regards:
Ajesh

I suspect the problem is in the BIOS. The basic problem is that your old RAM is running at 1600 MHz and the maximum speed of the new one is 1333 MHz.
You must go in the BIOS and look around what is possible to do in order to decrease the speed of the 4 GB stick to 1333 Mhz (JEDEC #5) to have any hope of using the total 6 GB

Thanks. There is no option to reduce the clock speed in BIOS. If you can please guide me how to do that?

Did you do the following as indicated in the manual ?
Memory size mismatch
Press <F2> (during POST) to enter the BIOS
utility, then press Exit in the BIOS utility to
reboot.


I suppose you did. But I am out of ideas.
Yes thats right, Thanks anyways.

I've had this happen before. I found no fix and assumed thet were incompatible. You should suspect the same unless you have some other way to test them in a different machine.
