Will these two Ram be compatible?

I read online if the specs are the same they should work together but seeing as they're different model numbers I wasn't sure.

When mixing modules it's hit and miss , won't know till you try them.

There can be issues when mixing even identical modules purchased separate times.

 

[atljsf]

theoretically yes, same voltages, same speed and same latency, quite high i must say

the one who decides if it will work is the mainboard

why do you want to get 24 gb of ram?

i would sell the 2x4 kit

Well even if they are the same exact model they may not work together if bought in separate 2x kits. This is because if they are made from different silicon production lines, there may be microscopic variations that may be just enough to cause errors between the other set. Kits are sold in 2x and 4x for a reason: they are made from the same production line and tested at the factory together. Now this doesn't mean the above won't work together, it just means there's a chance they won't. But changing up memory sizes like above can further increase chances of issues in dual channel mode.

Isn't 24 GBS of ram better than 16? I just ordered the 16. I've had the 8gbs.

 

[Dark Lord of Tech]

They might not run together when mixed , you won't know till you try to boot with them installed.

 

[atljsf]

well, more the better, but 16 gbs is mostly enough for all game and most tools out there

as you see is not guaranteed to work well together, probably will but i would remove the old modules and use the new ones

sell the old and recover some money

Ram is sold in kits for a reason.
A motherboard must manage all the ram using the same specs of voltage, cas and speed.
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 4 sticks are involved.
That is why ram vendors will NOT support ram that is not bought in one kit.

That said, go ahead and try them.
I put your odds of success at over 90%.
Put 12gb on each channel.
If you have a problem, sometimes you can fix it by increasing the ram voltage a bit in the bios.

Yes, there are almost no negatives, to more ram. 24gb beats 16gb.
Technically, your hibernate file grows from 8gb to24gb.
Used to be an issue when ssd devices were 40gb; not so today with cheaper/larger ssd devices for windows.

Try them together and if it don't work try your new pair by themselves.

Hey, just installed the 16gbs of ram with the 8gbs. How will I know if they're working together? The computer says I now have 24 GBS , is that an indication it worked? Thanks.

 

[atljsf]

usually yes, if system boots and report the ram, it should be working

you can run some tests but the real test is apply load, play some games or edit videos to load ram and see how responds
