Hello all. So i have a custom build, but im using the ram from an old computer that I had. When i go to the website i purchased the computer from, it only says "12GB DDR3 (PC3-12800)" for the ram. This is the link to the PC the ram is from http://www.woot.com/offers/hp-envy-quad-core-i7-desktop-w-12gb-ram-1 but again im only using the ram.

I just ordered a GTX 1070 and want to get some more ram, i would like to order https://www.amazon.com/dp/B00J8E8Y5C/ref=wl_it_dp_o_pC_nS_ttl?_encoding=UTF8&colid=3Q0U8K5K00IG2&coliid=I15SYFXJ9XWRFG&psc=1 but im not sure if it is compatible. Is it compatible or do i need to choose something different, and if so what do i look for. Thanks!

I've unselected that solution choice for you.

The Kingston RAM you linked in your first post would work perfectly with that CPU and motherboard combination. It's a good set of RAM, so you would be good to go if you wanted to order them. You would get a slight performance increase with 1866 frequency RAM, and not be taking the risk of an unbootable system by mixing RAM modules.

DDR3 PC3-12800 = DDR3 1600 (your old RAM)
DDR3 PC3-10600 = DDR3 1333 (the RAM it says you have on the website)

The Kingston RAM you listed is DDR3 1866, so if it DOES work together the newer sticks would slow down to match the older.

We don't recommend mixing and matching RAM, as it's a 50/50 shot in terms of the different RAM modules working together. Unless you're planning to use your computer for very demanding gaming or audio/visual editing the 16GB Kingston pair you linked should be plenty for your new rig.

So how much slower is my ram (PC3-12800) from the ram im looking to buy? Also, If i want to just buy more ram without a compatibility problem, should i just get any ram that is PC3-12800?

By this I mean would I'd be smarter to purchase the 16gb with faster speed. Or just upgrade my current ram with more sticks with the same speed

So would you suggest buying this ram and getting rid of the 12gb I have now. Or finding ram with the same speed as the 12gb I have now and upgrading that
