Can I have 24gb ram?
Posted by NINJAOuterSpace@reddit | buildapc | View on Reddit | 23 comments
My motherboard supports up to 64GB DDR4 but has only 2 memory slots. Currently, I'm using 8x2 3200MHz. If I replace one of the 8GB stick with a 16GB stick of the same brand, frequency, and voltage, would it work with dual channel for a total of 24GB?

It won't be faster, I would get another 16gb

Go to the QVL list of your motherboard and see if is any 24gb kit included if not probably work but without the expo profile or it will have isues.

I'm wishing I bought 2x64GB sticks now.

It really depends on your use case.
Technically it is possible, but you would get a much more stable setup using a paired couple.
It is really only useful to mix if you really need big amounts of ram for heavy loading of models and si.ilar (autocad or rendering).
Then a larger amount of slower RAM might be useful. But in general most uses will be geared towards using paired couples.

If I have dual slots and use 1 slot for 16 gb And put another 16 gb on the other one which is of different brand will it be good I am buying a laptop what to go for 8×2 or 16×1

It will likely work but it also might not, possibly not at full speeds. Depends on which components are on the RAM. Different dies from different manufacturers might cause issues. It's just better to use one matching kit. In extreme cases, components might even vary between sticks from the same brand and product line

yes

I have 24GB on my PC, but it's 2x8 and 2x4. I would just get a 2x8 to run with your existing 2x8, or 2x16 and toss the 2x8. You can get a 2x8 DDR4 for $30, and 32GB is plenty for gaming. But of course if you get the 2x16, you can always throw your 2x8 in there and see if it works for 40GB total.

This has been answered pretty well already, but all the people talking about instability may be a bit overhyping it. I have had to do this with laptops where one a stick was soldered on and the other one could be replaced and never had instability issues. I have also had to do this with servers where i couldn't afford $5000 in matching ram so used what I had including different brands and sizes and they were rock solid for years. Now if you want to over lock your ram or tweak voltages or other things all bets are off, of course.

Don’t. Get two sticks of the same size.

Thank you guys, I guess i'll just buy two sticks of 16gb. I am just gaming

To save a buck, buying another stick of 16GB to replace one of your 8 GBs will work just fine. Just remember that the faster stick will match the speed of the slower one or they will both run at a speed that they can both run stable.
It is true that mixing sticks can cause issues, but your PC can handle it and worst case scenario, pull out the other 8GB stick and now you freed up the other slot for another 16GB stick.

It would work as flex, not dual channel. You might also encounter some performance issues but they are minimal. The increase in performance is not significant but very much noticeable. So yes, you can absolutely have 24GB of ram

If you need more ram you are better off running 2 x 16 pair then mismatched sticks.
Sebas_chan15@reddit
I mean, you definitely can, now, would it be a good thing to do? No, as it would be working in single channel for one of the sticks, and dual channel for the second one, also, the frequency wouldn't be kept at 3200, you'll still have 24 gb but it wouldn't actually provide you with the full powrr of having it in dual channel, so just buy 32 gb, two 16 gb ram sticks, they ain't that expensive nowadays
ldontgeit@reddit
You can, but the rams will run on the lowest speed of the 2 and only 16gb will work in dual channel if im not wrong.
Better go for a 2x16 kit tbh.
normllikeme@reddit
Just don’t. Match pairs. Ya it can be done but it’ll mess with the channel modes. It might do the mixed thing another poster said but it might kick it all to single or it might not work at all
Significant_Apple904@reddit
Yes, but if you don't want potential stability issues at 3200mhz, just get 2 exact same sticks
LightmanDavidL@reddit
Sell your current RAM and buy this...

Mixing kits is not advised even with modules of the exact same SKU, mixing capacity also mixes other things. You're asking for system stability, performance and boot issues if you proceed
Comfortable-Mine3904@reddit
While it will work, you should only ever run ram that is exactly the same model together.
clupean@reddit
In theory it will work in dual channel mode for the first 8GB, and in single channel mode for the remaining 8GB of the 16GB module. In practice it might not maintain the rated 3200MT/s speed.
If you actually need more than your current 16GB of RAM, it's safer to buy a new 2x16GB dual channel kit and sell your current 2x8GB kit.
kaje@reddit
It would run in flex mode. You'd still have 16GB of dual channel, the left over 8GB would run in single channel.
