BSOD after taking in PC to repair shop

When seating RAM modules in their slots, it's important to seat them firmly and properly --

Believe it or not, but I once had a problem with seemingly bad RAM and tons of memtest errors when I realized that I was seating the modules by pressing down on their edges until they clicked into place. Turns out the motherboard was flexing too much under the pressure and the center of the modules wasn't making perfect contact like the edges were.

I ended up pressing my fingers against the motherboard from the other side to stabilize it while seating the RAM and pressing down along the entire length of the module, edge to center to edge.

Any and all memory errors magically disappeared.

So while this might have nothing to do with your scenario, I thought it would be worth mentioning...do doublecheck that your modules are really firmly in place.

Make sure you are testing both the RAM sticks and their slots to determine which one(s) are at fault, then try running without any stick at fault or replacing it.

The steps to check both the sticks and slots are here: RAM - Test with Memtest86+

Alright, reseated my memory and ioncreased the voltage to 1.56v.

Lets see if this helps.

Still crashed

Should I try setting the voltage to 1.65v?

That what my old memory used:
OCZ DDR3 PC3-10666 Gold Low Voltage Dual Channel - OCZ

But I just bought them in August.

leave one of the sticks installed. try them all. see if it crashes.

I suspect you either have the wrong speed or the memory you have the bios is having issues with it.

I've bought my share of memory that just wouldn't work right even though it's specs matched my motherboard's specs.

I tested my memory again and it shows no problems...this is getting bad.

I don't understand how it could fail Memtest then pass.
