A:AnswerHi,
Seems like it'd depend on the CPU being used, please refer to information regarding compatibility provided in the motherboard's manual/product page.
For any other questions related to the memory itself please contact us: support.corsair.com
A:AnswerI would not add ram that does not match what is already in the system.
The best thing to do is go to crucial.com, let them scan your computer, and they can tell you what you can use.
A:AnswerHi,
It says right on the HP site that for upgrades you'd have to look at 2666MHz kits: https://support.hp.com/us-en/document/c06020308, I'd stick to that but please do contact us if you have any further questions: support.corsair.com

A:AnswerYou can check the Asrock Memory AVL for memory that has been tested to work with your specific motherboard. It may or not be there as they usually test only a few vendors. But an X470 MB should run just about any brand name memory at 3000 or 3200 Mhz. Higher than that and it becomes harder to know without testing.
A:AnswerHi Andrew,
I'm not finding a product page nor more information on that model. Please refer to its manual. If you can have DDR4 3000MHz 2x8gb DIMMs then this will work.

A:AnswerHi Diego,
This kit would work to replace what originally came in the system. If you do have any other questions please do contact us: support.corsair.com
A:AnswerIt is compatible. 3000mhz is its rated overclock speed. All DDR4 Ram defaults to 2133mhz on install. You have to set it to rated speed in bios.
