probably no, 32 bit systems have an under 4Gb limit. looks like 2 memory slots 1,2,4 and 8Gb supported.

sad how, how fixya AI guessing wrong??? pathetic, mess....

HP does not support this quote

The BIOS does not do that!
what HP, it has full name and model.
the MMC controls this, and is very strict. (mem-managment controller)
the memory you are buying is no good. for YOUR PC.
this is so very common
and worse every year,
ever heard of Crucial or Kingston memory
they can fit up memory for you, it very complex.
not just DMM1, 2,3, but speed, min.
density rules.
chip count rules
chip voltage, 1.3. 1.5 or both or?
Total memory max allowed and PER SOCKET !
and even number of chips per side of stick , rule.
that worst was intel i5 old processors.
those are facts, and only the exact motherboard you have a
and what processor is there, (and if mmc is external to processor that)
matter.
? this?
M1070n

finding data on such and old box.
is not easy but google can dig up bits.
why not ask Kingston? for help,.

key facts are, (besides old)
HP Media Center m1070n Desktop PC
Intel Pentium 4 520 / 2.8 GHz
Intel 915P Express (my guess, mmc is inside here)
oops

• 512 MB / 4 GB (max)
• Memory Speed 400 MHz
• Memory Specification Compliance
  PC3200
• Features
  unbuffered
• Configuration Features
  2 x 256 MB
• Technology
  DDR SDRAM
• Installed Size
  512 MB
• Data Integrity Check
  non-ECC
  
• 4 GB
• Form Factor

looks like 1GB max per slot , 1 to 4.
good luck finding SDRAM in 2017 that works.

why not find a newer box? (pc) say 2010 or newer.,
they will run better and can buy ram easy
vastly better.... even Goodwill has them for few bucks
or this.

the specs for your computer, it states that it is equipped with 2gb of memory 2x1gb and max at 2gb, so I doubt that any higher memory upgrade installed would work, or else it would cause your system to crash or even damage it.

if you are using a 32 bit operating system it will not recognize all of the memory in some instances or the mobo is not designed for more than 2 gb maximum check the mainboard (motherboard) website for specs on your model. sometimes you have to use 64 bit operating system to be able to get the full use of memory over 2 GB

First find out if 4Gb sticks of the right type are available for your machine, and that the machine supports that much RAM. Then make sure you carefully order 2 x 4Gb sticks.

If you are using the XP or Vista OS, if you are going to install more than 3 GB of Memory then it fails to show up on the computer properties.

Once you install the memory then you may check the BIOS for the memory installed in the system, the BIOS shows the exact amount of memory installed in the system.

You system is capable of 4 GB of RAM.

If yours is a PC, Windows Vsita 64 bit should recognize 4 GB RAM. Have you tried the 64 bit bootable linux? Try with that. If you see less than 4GB, then you must check your BIOS for some setting which is the setting to share to the graphics memory or some limit.

windows xp will not show 4 gb of memory, it will support it but not show. you would need vista 64 bit to be shown the full 4gb of memory
