BOSD 0x00000124 Please HELP!!!

u sure?

Yes. If you aren't confident, remove all that motherboard software and get that BIOS updated. If neither of those work, replace the CPU.

There is a slim chance this may be a motherboard or RAM issue, but it appears too consistent to be mobo and it always refers to the CPU L2 cache as being at fault, which leaves out RAM. Still, the chance is still there, albeit small.

Understand that this WHEA crashing you're getting isn't Windows telling you it's the CPU, but rather it's the CPU telling Windows! I have more confidence on a diagnosis related to these types of crashes than most other crashes.

After checking my bios of my asus p8h61, I noticed that the dram supported was "only" 1066 mhz and 1333 mhz and Im using a 1600mhz corsair ram is that a problem?
This mobo:
ASUS P8H61-M LE/CSM R2.0 Socket 1155 Motherboard - ATX, Socket 1155, Intel H61(B3) Chipset, 2200 MHz DDR3 (O.C.), 8-CH Audio, Gigabit LAN, USB 2.0 at TigerDirect.com
and this ram:
Corsair CMZ8GX3M1A1600C10 Vengeance Desktop Memory Module - 8GB, PC3-12800, DDR3-1600MHz, 240-pin DIMM, 1.5V, CL10, Intel XMP Ready, Unbuffered at TigerDirect.com

exactly where I got them from.

That does sound like an issue for sure. I can't see how that translates into the particular WHEA faults you're getting, but stranger things have happened. If you must, approach the RAM first before tackling the CPU. Honestly, I prefer otherwise, but it is at your discretion.

the normal ghz for the cpu is 3.4 right? and the turbo is 3.8?
While in the bios I also saw that the turbo cpu thing was weirdly set at 3.9..something.
Weird cuz I did not overclock, well I ddnt consciously of overclock.

Some motherboards have "normal" default settings set to actually overclocked settings that it deems is "safe for anyone" when sometimes it's not. See if there's any "safe" default settings in your BIOS that you can set too.

I set it back to its original value at 3800 mhz and its working fine for about 1 day.

Go ahead and run Prime95 again for an overnighter.

I also set my bios max temp at 48 celsius, if it gets to 48 celsius my heatsink will work 100%. All night long leave it on?

If the temps appear stable at a good temp for 30 minutes, then it should remain that way for the duration of the night.

Oh, and remember to set Prime95 to Large FFTs.
