Question Need some help finding compatible memory.

May 17, 2019
I currently have 8GB of memory in my computer and I'm looking to up that to at least 16 but I'm having a lot of trouble finding what is compatible. I tried looking for some that were just the same as what I currently have but I can't find it anywhere.

Any help or suggestions would be greatly appreciated.

I have already tried a Crucial Scan and it did not work.

My MB is HP 8433.
Go to a ram web site like Kingston or crucial and access their ram upgrade app.
Enter your motherboard and you will get a list of supported upgrades.
If either says an added 8gb is supported, buy the exact stick that they recommend.

Your motherboard has only two ram slots.
If no joy from above,
Ram is sold in kits for a reason.
A motherboard must manage all the ram using the same specs of voltage, cas and speed.
The internal workings are designed for the capacity of the kit.
Ram from the same vendor and part number can be made up of differing manufacturing components over time.
Some motherboards, can be very sensitive to this.
This is more difficult when more sticks are involved.
That is why ram vendors will NOT guarantee ram that is not bought in one kit.

If you do buy more disparate sticks, they should be the same speed, voltage and cas numbers.
Even then your chances of working are less than 100%

What is your plan "B" if the new stick/s do not work?

If you want 16gb, my suggestion is to buy a 2 x 8gb kit that matches your current specs.
Then, try adding in your old 8gb,
If it works, good; you now have extra ram.
If not, sell the old ram or keep it as a spare.
