That is the answer. Maybe. They can't actually make identical RAM sticks any more than they can make identical CPUs; fabrication processes just aren't that exact. So in the same way CPUs are tested and given a model name based on how they perform in testing, so are RAM sticks. The RAM will run in flex mode. You'll get 16GB running in dual channel, and the leftover 8GB will run in single channel. PCPartPicker Part List. Type. Item. Price. Memory. Crucial Ballistix 32 GB (2 x 16 GB) DDR4-3200 CL16 Memory. $112.99 @ Amazon. SkyNetRising said: It might. First 8+16 will not run in dual channel mode. It will be either single channel or flex mode. 8+8 will run in dual channel, so better. But if you're not using ram modules from same kit, this can introduce compatibility issues. So best option is to get either. 8GB+8GB dual channel kit or. I currently have two sticks of Adata XPG GAMMIX D10 8GB DDR4-3000MHz and I was looking to get 32gb of ram but can't seem to find this stick exactly in stock. I was wondering if anyone knew good ones I could use that would be compatible with it and not cause problems. My current mobo is ASRock Z390 Phantom Gaming 4S-IB. Mixing the two 8GB and two 16GB RAMs isn’t impossible, but many restrictions come with it. The speed and performance may be opposite of what you imagined. Myths and misconceptions highlighted in the article need to be forgotten completely, and necessary guidelines followed. Consider using similar RAM sticks for effective performance and less When workloads exceed the dual channel RAM usage of 16GB (8GB+8GB portion of the 16GB), it then suffers on performance due to lack of dual channel speeds. Like the other person who posted, best to replace the 8GB RAM with a 16GB stick if you can. I have 2x 16GB of 3200mhz of ram at the moment. Will getting another 2x 16GB 3000mhz instead of 3200 affect system performance or compatibility since it is slower? I can get the 3000mhz about $60-$70 dollars cheaper than the 3200mhz, so if it doesn't affect performance I thought I'll save some money there. Yes, you can use 4GB and 8GB RAM together. But you may experience a performance drop while using RAMs of different sizes. But you can reduce that performance deficit to some degree by using two different-sized RAMs of the same bus speed. But, Tech experts always opt for using the same-sized RAMs. Curious to know can I use 8GB and 16GB RAM together. .

can i mix 8gb ram with 16gb ram
