Question 1

does this come with 2 four gigs, one eight gig, or two eight gigs?

Accepted Answer

G.SKILL Ripjaws X Series 8GB (2 x 4GB) ...

It says 2 x 4GB and my package was compliant with that.

Question 2

do you get 2 when you buy it or you get 1?

Accepted Answer

if it says (2 x 4GB)  that means 2 sticks of 4GB RAM= 8GB Total RAM
if it says (1 x 8GB)  that is 1 stick of 8GB RAM= 8GB Total RAM
...(4 x 4GB) is 4 sticks of 4GB RAM= 16GB total RAM
and so on

Question 3

can I switch my 4GB with this new 8GB on my Lenovo laptop?

Accepted Answer

No, sorry. This is for desktops only. You will need to find the appropriate speed in the laptop ram section. Once you find it, you will to also check to see if your laptop can support more ram than what it came with.

Question 4

Question 5

If I buy 2 sets of these will they work in a my PC(Alienware Aurora R3) which requires 4 sticks?

Accepted Answer

They should. Just ensure that the Pin amount is the same (These are 240-Pin). I also don't see why a PC would require 4 sticks, it probably just has 4 slots available. I don't think you would have to utilize them all. Good luck :)

Question 6

I'm looking at a PC build, and the CPU I've picked out is an LGA 1150. Would these be compatible with that CPU, or would I need to find some that specifically state that they are compatible with an LGA 1150 setup?

Accepted Answer

Yes these are compatible as long as your motherboard has DDR3 SDRAM slots which most do. I have an LGA 1150 format CPU with these on the motherboard and they work great. Just follow the instructions on which slots they need to be in on the motherboard if it has more than two slots for RAM and you don't plan on using them all.

Question 7

Does this work with an AMD MoBo?

Accepted Answer

I have ripjaws X  F3 1600C9D-16GXM   (2 X 8G sticks)
in a DZ77RE-75K motherboard  (LGA 1155)

can i add 2X4G sticks to fill the other two slots, and memory performance
would not be hurt by the difference in memory sizes (since one pair is 8+8 and the other pair 4+4)
OR
does it have to be another set of 2X8G in order to match?
thank you!

Question 8

Do you folks use it on ASUS MB P6X58D Premium or/and P7P55 WS Supercomputer?  Your help is truly appreciated.

Accepted Answer

Yes, this G-Skill memory should work fine. In my X58 motherboard all memory automatically runs at 1333MHz until you enable the "XMP" feature in the BIOS setup screen. XMP reads the faster eXtreme Memory Profile info embedded on the RAM modules and boosts the RAM so it runs at it's rated higher speed.

Question 9

Can I mix match this ram with the one I'm using at the moment (Module Manufacturer: ASint Technology; Module Part Number:                                                             SLA302G08-GGNHC) but both of my current/this have the same voltage which is 1.5v and different CAS Latency. Any thoughts? Please let me know, thank you.

Accepted Answer

What will typically happen, is the faster RAM will downclock itself to match the slower RAM. But if the faster RAM cannot support the slower RAM's timings, then you'll run into serious problems.

Best thing to do, is if you have 4 slots, fit the 2 types into the color coded slots (So if you got 4 slots, 2 will be one color, and 2 will be another). If it doesn't boot or runs erratically, just remove your old RAM.

If you're not running dual channel (2 memory slots), then scrap the old RAM and use these. If you're running Quad Channel (8 memory slots), then don't get these and go for the quad channel pack.

Question 10

Will this ram work with a Asus z87-a Haswell mobo ?

Accepted Answer

Generally speaking, the motherboard will give the stats of the RAM Supported, but most motherboards will default clock the RAM to 1,600mhz. So if you get 1,866mhz RAM, you need to go into the BIOS and under memory management you'll need to select the 1,866mhz power profile.

But this RAM will work with that motherboard. DDR3 will fit into any MOBO that can support DDR3, just the motherboard will clock the RAM to its stock settings. (So if you put 1,600mhz RAM into a mobo that can only support 1,333, the RAM will be clocked down to 1,333.)
