CPU TEST

This indicates that your CPU is running without errors.
So you have some bad RAM it looks like. That shouldn't cause a 124 (that is from CPU voltage).

Stop 0x124 - what it means and what to try
As mentioned in this post, this stop code can be from any hardware.
RAM is mentioned as a more likely culprit, from my experience this is true.
It is important to note that there are many different possible MCE triggers, and one machine's stop 0x124 is likely to be entirely different to another's. Hence, it is best not to place too much emphasis on very specialised ways in which other individuals have resolved their own 0x124 problems - the more exotic the other machine's MCE solution, the less likely it is to apply to your own setup.
Since the OP has not been overclocking, the chances are less that CPU voltage is a cause, but still possible.
I have OC'ed my CPU to 3.84GHz on the stock CPU voltage setting, had to bump it a little when I went above 4GHz.
If the CPU voltage is increased it will generate more heat. This should be avoided unless necessary.
stavee, if you want to check your CPU again, use Prime95 torture test. This will stress the CPU more and some of the RAM.
This is the recommended test to run after adjusting RAM settings which have passed memtest86+.
First open RealTemp to monitor CPU temperatures, don't go over 78 degC.
Open Prime95, stop the test if it starts automatically.
In Advanced tab select 'Round off checking', in the Options tab select 'Torture Test...', in the window that opens select 'Blend', after 'Number of torture test threads to run' enter 8, then click OK to start the test.
Watch the CPU temps.
Run this test for a minimum of 2 hours, or, as Lordbob mentioned 12 hours is considered the minimum by some.
If Prime95 has an error, stops on it's own, or you have another STOP error, bump the 'DRAM voltage' to 1.550v.
It is currently at 1.500v according to previous BIOS snips.
Then run memtest86+ or Prime95 again.
