Memory causing BSOD

I recently built a new PC specs here:

Intel core i5 3570k Ivy Bridge at 3.4GHz
Asus P8Z77-V PRO
EVGA GTX 570 1280MB
16GB Corsair vengeance PC3-14900 (1866) (4 x 4gb)
2TB Seagate 6gb/s hard drive
Windows 7 Home Premium 64bit
(This is all the system specs I felt where needed, if you need any more please do say)

Now when I used memtest to define whether or not I have faulty RAM I ran a test to start with on all four sticks. Now I had a lot of errors so I decided to test them all individually. I tested them all individually but did not find a single error on any of them so I decided to add one more each time and test again each time. Having 2 or 3 sticks showed no errors with memtest but the moment I added the fourth stick and tested the errors started showing up again so I tested the motherboard slot with the just the one stick in it and it didn't show any errors. So essentially when I have 1,2 or 3 sticks of 4gb of memory in the motherboard it does not show any errors and I do not get BSOD's (so far anyway) but the moment I add another stick of memory and scan with memtest for errors I get tonnes and if I boot windows at some point I will receive a BSOD. (Also I can't be putting the RAM in the wrong slots on the MB as it only has four).

Any ideas?

I would try manually adjusting the memory settings in BIOS.

You can try decreasing the speed and/or increasing the voltage.
If you increase voltage, do it with the smallest increments possible, one step at a time and test it.

Also, sometimes changing a setting from "Auto" to the manufacturer's spec setting can make a difference.

Thank you very much.
I lowered the speed and did a full test just to be sure and it showed no errors. Any idea what is causing these errors when I have the memory set to 1866mhz?

It's my understanding the 3570K memory controller supports DDR3-1333 and DDR3-1600 memory.
If you're running at 1866 it is over "advertised spec".
There's nothing wrong with that as long as the system is stable...

Adding the 4th stick at 1866 just pushed it over the edge of what your system can handle with that configuration.
Sometimes running 4 sticks of RAM does require a bump up in voltage, even if using "advertised" speed.

I'm assuming you tested stable at 1600, so you know you can run that way.
You could now try increasing the voltage to see if you can find a point where you can run 4 sticks at 1866.

I really don't believe you will notice any difference between 1600 and 1866, but the choice is yours.

If you do want to bump memory speed and voltage it might be good to create a thread in the Overclocking forum.
Someone there might have a similar setup to yours and give you better advice...
I'm not sure what the "safe" limit is to bump memory voltage with the 3570K and your RAM, and I'm assuming your memory is 1.5 V.

Hope this helps,
David

Thanks for the explanation, my ram is on 1.5v at the moment so I will have a look around and see what the voltage I need is.
