Did i buy a wrong RAM, if not, why does it show blue screen?

[Dem_Mak]

Thank you so much for clicking on this, i'm new to all the computer stuff and i really need help.



I have a motherboard ASUSTeK Computer INC. P5Q-PRO (LGA 775), which supports 1600 / 1333 / 1066 / 800 MHz and has a maximum capacity of 16GB of RAM. I'm using Windows 10.
Right now my RAM is 4,00GB Dual-Channel DDR2 @ 400MHz .
The RAM i bought and tried to install is 8,00GB Dual-Channel DDR2 @ 800MHz. It's true that it was very cheap (15$, unused, on Ebay, from China), but i don't think that's the problem.
I have tried installing it, but it showed me blue screen every time i turned on the computer, and the computer came up with a different error. Could it be, that i bought the wrong ram?

Here are the blue screen errors that have showed up on my screen:
ACPI_DRIVER_INTERNAL
IRQL_NOT_LESS_OR_EQUAL
KERNEL_SECURITY_CHECK_FAILURE
SYSTEM_THREAD_EXCEPTION_NOT_HANDLED


I've googled them but i couldn't find the problem for my computer and i'd very happy if someone could help me, thank you so much!

That does sound like RAM. Can you download and run Memtest: http://www.memtest.org/

Sounds more like faulty RAM than wrong RAM.

OK... see the top of the listing? Specifically, where it says this:

Attention: It is high density.It is only compatible with AMD motherboard and can not work in any intel motherboard!
