Hi, I just bought 2 4gb sticks of GSkill 1600 RAM from Ebay,
Waited all day for UPS to show up, had my hopes high.
Placed the ram into the slots, (Already had another 2x4GB sticks) which made a total of 16GB in 4 sticks.

Started up PC, and like 3-4 secs later, it shut down. Then tried to start up again.
Removed the 2 New sticks I got, and tried to start.. It Started
Removed my 2 Old sticks, Put in new sticks. No start
Put 1 Old + 1 New. It started.
Removed 1 new stick and replaced with other new stick. No start.
I have reason to believe one of the new sticks is faulty. Because no-matter which slot, as long as the "Faulty" stick is in, the PC keeps shutting down, but when I put all 3 but the faulty one in, it works. Any solutions?
I don't want to open a dispute on ebay but I will if I have to. I'll be damned if I'll waste 25/30$ on letting something like this slide.

Motherboard and CPU are barely new.
Bought in Nov of 2014..

i5-4690k
ASUS Z97-AR
1 set of ram: GSkill Ripjaws X 1600mhz. (Original)
2nd set: GSkill RipJaws 1600mhz ("Faulty set")
OCZ-ZT 650W PSU
Asus GTX 560ti GPU

I would first determine if it is only one stick of RAM that is causing the problem - this make take time, but it would require putting in two sticks of RAM in this type of order:
1) A+B
2) A+C
3) A+D
4) B+C
5) B+D
6) C+D

If any one of the sticks fails every time, and the others all work - you have identified the bad RAM stick. If it isn't a consistent error, then it could be a problem with the mobo.

When you install all 4 sticks - make sure to alternate the memory - DIMM_A1 and DIMM_B1 are meant for one "set" and DIMM_A2 and DIMM_B2 are meant for the second set. The arrangement on the mobo is A1, A2, B1, B2 (it doesn't matter if you are looking forward or backward - just make sure that the "even" slots and "odd" slots are used...

When you mention for example A + B, Are you implying I should use the A1 Slot and the A2 Slot?
Or are they identified for the sticks?

labeled each stick, since i think that's what I was suppposed to do.
A = Old 4Gb Stick
B = Old 4GB Stick
C= New Stick
D= New stick (considered faulty)


A+B = Sucessful Post
A+C = Successful Post
A+D = Failed Post
B+C = Successful Post
B+D = Failed Post
C+D = Failed Post

Tried to move stick D to different Dim slots when I had all 4 sticks in slots
Didn't matter what slot I moved it to, it would still fail to post or boot.
