HP Envy 750-427c RAM Upgrade

[Dennis1965]

I recently purchased an HP Envy 750-427c Desktop system. In looking closer at the specs for this system it only mentions that 4GB and 8GB UDIMMs are accepted in the 2 slots on the motherboard.

Is there no way to upgrade the RAM beyond 16GB? Why wouldn't it accept two 16GB DIMMs? I'm running 64 bit Windows 10 on this system, which can address much more memory. I'm just curious if there is really a 16GB limit on these systems. 16GB is more than adequate for my purposes at the moment, but I can't say that I'd never want more RAM eventually. Why would the motherboard be limited to 16GB?

Hi:

You ask a good question, but unfortunately I would only be able to give you a theoretical answer.

I know that on motherboards with 4 memory slots, the H170 chipset supports a max of 4 x 16 GB of memory, for a total of 64 GB.

The motherboard in your PC has two memory slots.

HP states the max is 8 GB per slot, but logic would indicate that you could install 2 x 16 GB, and have a max of 32 GB.

Unless someone with your model (or similar model with the same motherboard) had the $$$ to gamble on a 16 GB chip, can definitely tell us yes or no, we can only sit here and wonder.

I have an old HP 6910p business notebook.  All the specs around (including HP's) stated the max memory was 2 x 2 GB. 

But I knew that the Mobile Intel 965 chipset supported 8 GB of memory (2 x 4 GB).

I did risk $65 bucks on the theory that it would run 8 GB despite the specs, and came up a winner.  It ran it just fine.
