Mixing RAM With Different Speed and Latency. Technically, you can install memory units with different speed and latency. But whether the system boots is uncertain. All the memory units installed in a motherboard run at the same frequency. If your system already has slower RAM, there is no point in adding faster RAM.
If you want 16gb go for 2 8gb modules. That way you take full advantage of the dual channel architecture. On topic though the extra 4gb probably wont be of any use to you. Plus if the new modules are different speeds to the one you have they will all run at the slowest speed. Ie. 2x 8gb 3200 and 1x 4gb 2666 they will all run at 2666mhz.
Can I safely mix my: Crucial Ballistix Sport 8GB Kit (4GBx2) DDR3 1600 MT/s (PC3-12800) CL9 @1.5V UDIMM 240-Pin Memory (BLS2KIT4G3D1609DS1S00) With the: CORSAIR Vengeance 16GB (2 x 8GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory (CMZ16GX3M2A1600C10)
PC Format Magazine/Getty Images. Most users need about 8 GB of RAM, but to use several apps at once, you might need 16 GB or more. If you don't have enough RAM, your computer will run slowly and

That will force BIOS to see the change in RAM config. Of course, I can't guarantee the PC will work with 80 GB installed, even after you mix the pairs, since that is an "unusual" config and never validated by Dell. If it does work, use CPU-z (free) to check RAM speed and if it's running in single or dual channel mode (CPU-z: "Channel #"). If

For example: Let's say you have a 4GB stick and a 1GB one, and that you want Dual-Channel. With Intel Memory Flex, you would then have 1GB + 1GB of RAM in dual channel mode from each sticks, while the remaining 3GB from the 4GB stick would still stay in single-channel mode.
Shouldn't matter much for you tbh, games and whatnot should still make full use of those first 16gb in dual channel. Since you want more RAM, and assuming that you're running out of it for some of your tasks, so the slowdown after you go past 16gb is way more negligible than the actual lack of ram.
Mixing different types of ram can cause issues sometimes, it’s a coinflip. Using different speed(Mhz) would make the sticks both run at the lower speed RAM stick, meaning combining a 2666Mhz with any stick that has more than 2666(3200, 3600 and so on) would make them both run at 2666.
G.Skill and most memory makers do not guarantee two kits of RAM to work together. So if you are hoping to use two of these kits on a MB that supports 8 x 16GB RAM, you would be better off buying a single 8 x 16GB kit instead. What is the meaning of not giving a guarantee that two 64GB kits will work together?

Jun 6, 2021. #2. You can be guaranteed that if dual channel is used, then this will fail. If you can live with going single channel, then it might work if the timings are reasonably close. You'd have to try to really know, but there would definitely be a performance hit. I wouldn't recommend it even if the third stick is a matching model/timing.

1. I have a Dell inspriron n5010 and I want to upgrade the RAM. It currently has 3GB of RAM. It has a 2GB stick and a 1 GB stick. I was thinking that I would replace the 1 GB stick with this stick that I ordered. I am pretty sure it has all of the right specs with 204 pins, SO-DIMM DDR3, and 1333 speed rating. It says that the RAM is universal. .
