Hi all,
Currently I am trying to install a 8GB RAM in my HP ab029tx(preinstalled 4GB).
I inserted it one the 2nd SODIMM slot available and it got clipped as normal.
But returning to windows , it is showing only 4GB(preinstalled).
RAMMON from passmark is detecting the RAM in 2nd slot as shown in below image.

But according to my windows10, there is no existence of the 2nd RAM.

I uploaded detailed result of RAMMON in html format in google drive.

I have checked msconfig and max RAM is unticked there.
And according to spec, it supports upto 16GB. hp link
Please help !!

Just as a first test, take out the 4GB stick and move the 8GB stick to the first slot and see what happens when you boot with just the 8GB stick in place.

 

If it works with just the 8GB RAM stick installed then at least the stick is good. I note that, from your image above, the RAM is by two different makers. RAM sticks are known to be sometimes fussy about what they are paired up with. Sometimes sticks of different sizes and from different makers will not work together.

 

If the computer works with the 8GB stick in slot 1, try adding the 4GB stick back in slot 2 and see if you get a total of 12. If you don't, the slot may be faulty.

hi Chris,

I tried by removing the 4GB and inserted the new 8GB in 1st slot. It didnt boot up. And the caps lock key light was toggling in a specific pattern. I gave it some time thinking it is doing something but no result. Then I inserted the 4GB RAM in the 2nd slot(see now the positions are swapped ,thus we can say the slots are working), and it booted up with the same old result( 4GB RAM detected)
Now can we say the RAM stick is faulty if CPU-Z and RAMMON is showing it ? And their configurations are identical in 20 different parameters according to RAMMON, except voltage, where 4GB support both 1.35v & 1.5v and the new one only 1.5v.

That voltage difference could well be your problem here if the rail voltage is at the 1.35V level. Is it possible in the BIOS to raise the rail to 1.5V ?  You might find it helpful to look at #2 in this topic where The_Patriot discusses this problem -

I am going to send him a PM to ask him to have a look at your problem - his technical knowledge in this area is well ahead of mine - but I suspect this is where your problem lies.

I would suspect the problem lies in different voltage ram modules...I would check the specs on the new ram, go into the bios and find the ram voltage setting, probably under the advanced motherboard tweaker (might be, probably called something else) and check what the voltage on the board is. If it doesn't match the new stick then change it to the new stick, save and exit, shut the computer off and try to boot it with only the new stick of ram installed, and see what happens.

thanks a lot, looks like it is a voltage issue only.
My processor spec

also says that it support only low voltage ram !!
according to RAMMON & hyundai semiconductor their RAM (my older 4GB) can run on 1.5 volt also.
But I am not seeing any option in BIOS to change voltage!

being a OEM computer, the option may not be there. Some Ram modules are simply incompatible, sad to say.  You might just have to RMA it for different ram.
