BSOD after upgrading &/or installing new memory module on brand new PC

Good day to all. Can someone please assist me, advance thanks..

I bought a PC with MSI mainboard, N430GT, with 2-2GB Kingston KVR1333D3N9/2G installed RAM (=4GB), 500GB HDD.
Everything works smooth until I read that I could upgrade memory up to 16GB max. BTW my OS is Win7 64 Ultimate.

So I decided first to buy and install 2pcs-4GB Kingston KVR1333D3N9/4G (=8GB), for a few days everything works fine as expected, I shut it down one night and the following day restarting my PC, it turned BLUE with messages., and then on as often as every 5 minutes or less it turns BSOD.

I asked my friends and told me to do a clean OS reinstallation and I did that, but the problem persisted as if nothing changed.

So I did a memory diagnostic and It noted that possible hardware problem.

I did immediately changed and swap back my original 2pcs-2GB memory, and surprisingly until this thread writing it is ok.

My mainboard supports dual channel (two slots only) and I want to know how could I checked which one of the two 4GB memory modules is not working, or is it safe to install only one 4GB memory to checked which of the two is working or both are not working?

Any immediate response is of great help. thanks.

The Kingston Value Ram (KVR) is known to be marginal and not even work in some PC's. The regular Kingston memory is usually OK but none of the techies that I know will use or recommend the KVR.

Check the MSI (or whoever the motherboard vendor is) site for your motherboard model (you didn't list it so I can't check for your). The N430GT is your video card, not the motherboard. Most motherboard vendors list compatible memory for their motherboards. Best to use memory that has been certified for the specific motherboard.

thanks for the info. appreciated much.

Lots of folks here use Memtest86+ - Advanced Memory Diagnostic Tool to test RAM.

It is fine to test the individual modules. Just find the first RAM slot (usually marked A1 or similar) and test each stick individually in that slot for at least 3 passes.

And/or test the two new sticks installed together.

Sometimes when all the RAM slots are populated there can be a drop in supplied voltage from the motherboard in some systems. This can be corrected by incrementally increasing the voltage in the BIOS settings by fractions of a volt.

So also run the test with all 4 in it too. If errors start showing up with all 4 then you can up the voltage one step, and then retest to see if the problem goes away.

i just finished memtest86_v4.2 downloading, hoping to clear things up. thanks.

thanks guys, my PC working nice again. one of the memory module defective have it replaced as it is still covered by warranty.
