Windows 7: 0x107 after 0xA, no pattern tho

Glad to hear your found a bad RAM card, hopefully this will solve the stability issue.

Run each of the other 3 cards for 7 complete tests of memtest86+.

Each test is different and all are important. At this point you don't want to go through this again next week.
This will take several hours for each card, best to run overnight.

Buying a single RAM card replacement is risky, it is always recommended to get all your RAM with the same timings, frequency and from the same manufacturer.
If you decide to get a single card, make sure the place you buy it has a good return policy.

Let us know how it's going.

so, i been using only 3 rams since last nite... but still i got a bsod this morning..
quite interesting.. since i enabled driver verifies yesterday
A device driver attempting to corrupt the system has been caught.  This is
because the driver was specified in the registry as being suspect (by the
administrator) and the kernel has enabled substantial checking of this driver.
If the driver attempts to corrupt the system, bugchecks 0xC4, 0xC1 and 0xA will
be among the most commonly seen crashes.
Arg1: 0000000000000081, MmMapLockedPages called without MDL_MAPPING_CAN_FAIL
Arg2: fffffa8006e3d0f0, MDL address.

This is what 'Driver Verifier' is suppose to do, it stresses the drivers to try and force them to crash.
Then you know which one is causing the problems.

mcdbus.sys is the MagicISO SCSI Host Controller driver, check for a new version or new driver: MagicISO - Convert BIN to ISO, Create, Edit, Burn, Extract ISO file, ISO/BIN converter/extractor/editor

This may help, but you still might have some hardware that is causing this driver to crash.

Did you run memtest86+ on the other three RAM cards, separately?

Bump your cpu-nb voltage to the next higher voltage, let me know what it is.

Then run memtest86+ on each card separately, as mentioned.
