Is this ram compatible with current ones I have?

[upwake]

This is the ram I have now in my computer, I've been needing to add more ram to my 2 empty slots for a while now my question is can I leave this in my ram slot and buy the 2x4 gskill ram from amazon and it be compatible? total ram I WOULD have is 12 Thanks!

Current one I don't want to get rid of: http://www.newegg.com/Product/Product.aspx?Item=N82E16820231277

Ram I want to add: http://www.amazon.com/G-Skill-F3-12800CL9D-8GBXL-PC3-12800-RipjawsX-9-9-9-24/dp/B004I763AW/ref=sr_1_3?ie=UTF8&qid=1427967765&sr=8-3&keywords=g+skill+ram



MB (just in case) http://www.newegg.com/Product/Product.aspx?Item=N82E16813157271

P.S this is with just 4gb, this is normal right? http://i.imgur.com/zcQjqyL.png

As long as the RAM is DDR3 it will fit fine. But I do warn you, don't mix ram makes and gHz. It can not work and mess up. Just to be safe always use the same RAM throughout, that's why they come in sets

Hope this helps.

I should of worded that better I know they will fit I just want to make sure that they will work full potential and compatible with each other. The timi g is the same, same make gskill, ddr3 same. So I guess I'm good to go and but it hub? Thanks!

The two memory kits have same speed rating, primary timings and voltage. This helps with regard to compatibility. However, the modules are of different capacity, probably have different sub-timings, and maybe use different chip architecture. This tends to make the modules incompatible.

So the two kits are really considered to be incompatible. But this also depends on the sensitivity of the memory controller.

There are two memory configurations that could be tried to see whether the two kits work together, or not.

1) Each kit configured in dual channel mode; 2 GB DIMM in slot 1, 4 GB DIMM in slot 2, 2 GB DIMM in slot 3, and 4 GB DIMM in slot 4.

2) Each kit installed in its own channel; 2 GB DIMM in slot 1 and in slot 2, and 4 GB DIMM in slot 3 and in slot 4.

If you are lucky option 1 may work with both kits operating in dual channel mode. Or, if option 2 works, then 4 GB of DIMM in second channel (slot 3?) will operate in dual channel mode with the DIMM's in first channel (slots 1 and 2), and remaining 4 GB of second channel (slot 4?) operates in single channel mode.

Adjustment of some voltages may be required.

Thanks brius for the detailed post! How would I know they are working properly once installed? Will windows say 12gb in use if it is working? Or if it isn't working will it say 12gb (8 usable) or something?

Basically the system should recognize ALL the memory (12 GB) in all of the configurations, and the system runs without any problems (no freezes, no crashes etc.).

Okay thank you Briss if it fails at least I'll have 8gb usable lol.
