So, if you have 8GB + 16GB sticks in dual channel pair, then you have 2*8GB working in dual channel and 8GB working in single channel. BTW, this doesn't apply to the other dual channel pair. You can have 8+8 and 16+16 in 4 slots, that rule only applies to one dual channel pair. Alternatively I could just buyt two more 4gb sticks bringing it up to 16GB but I don't know if this is better or worse than having the two 8gb. Motherboard is ASUS Z97-P, and the Ram installed currently is DDR3 1600 single/dual channel. Just worried about the buying Ram for the first time and dont wanna screw anything up! Theoretically, you can mix different RAM brands in your computer system, but you may encounter some problems. Sometimes mixing different RAM brands can lead to a drop in performance, but if you consider your options carefully, you may be able to avoid issues. One crucial factor that will undoubtedly cause a problem is using different memory types. Yes, just make sure you move the 2 8GB sticks into one channel, and the new 16GB one into the other. 9. [deleted] • 1 yr. ago. KimchiNinjaTT. • 4 yr. ago. get the 2 sticks. memory works in dual channels which can boost your computers performance, especially for AMD, up to 30%. 7. JammyJona. Memory in DIMM 1/2/3/4 based on motherboard markings of 1/3/5/7 2/4/6/8 shows as 1/4/5/8 in BIOS. Based on the configuration as received, it appears I may need to essentially superimpose the memory configuration and DIMM reference in the manual over any reference on the board or BIOS. If someone could verify, it would be appreciated. If it works with the existing 8gb of ram, well and good; you have 24gb to work with. Use memtest86+ to test the ram. You should be able to do a couple of full passes with NO errors. In the event that you have trouble booting, go into the bios and increase the ram voltage a touch. Cak7E0. Yes they can be mixed They will operate in flex mode. It is always better to have matched RAM for Dual Channel mode. i have 8gb single rank and 16 gb dual rank and for the 16gb is mt/s and 8gb is mhz so it this can mix? Your RAM has to be matching in everything but size and rank, although it is better to be exact. 1. It should work. You'll get 12 GB of RAM in total, but you won't benefit from dual channel - it works only if both modules have the same capacity. Since this is a DDR3 system the advantage of dual channel is relatively small and it's probably worth sacrificing for additional 4 GB. Some DDR4 systems have sigificant boosts from dual channel For this to work, the memory sticks should be identical. If the price for 1x16GB is less than twice 8GB, it could be benefitial to go for the 1x16GB. Likewise, if the 1x16GB is quite a bit more expensive twice 8GB, even if you can't get dual channel working, getting 1x 8GB may be worth it more. You need to look at how old your laptop is. Whether you notice or care about the speed difference is up to you. If you don't mind slower ram performance after 16GB of ram is used when using 8Gb and 16GB for 24GB total, then go for it. Just know that the chances of incompatibility are much greater when running miss matched modules. Buying your ram in 2x or 4x kits is best for compatibility. #1 Hello, i just ordered 16gb ram 3000mhz, because 8gb just wasn't enough for me. The ram that i ordered was the same speed and same manifacturer. Here is the ram that i bought: http:// Usually mixing RAMs is a bad idea and causes issues like this one. Sometimes even if you get the exact same RAM modules, the same issue will exist. The best thing would be to get a 32Gb kit but of course that will cost a lot more (considering your mobo supports it). Go to your BIOS and enable XMP mode.

can i mix 8gb ram with 16gb ram
