[SOLVED] Why can't I hold all these RAM? When Windows Fails

I set the frequency to DDR3-1333, XMP to Profile 1 with all 4 chips installed after pulling the MB's battery for 60 sec as per GSKILL FAQ and as I type now, Windows is up and at 'em with 15.9GB available. Problem solved.

So, I've been running G.Skill Ares DDR3 2x4GB C11 2133MHz RAM for a while on my MSI Z77A-G45, along with my i5-3570K. Been through Windows 7 and now on Windows 10, installed on my 240GB Samsung EVO 840 SSD, correctly TRIMmed and overpartitioned and such. No problems, just 8GB is not enough RAM. Star Citizen is a big universe.

Anywho, bought some more RAM of the same sort but, silly me, it wasn't 2133MHz. Computer booted fine, but crashed whenever it tried to start using anything beyond the first 8GB. I sold that RAM and bought some more 2x4GB 2133MHz C11 DDR3 G.Skill Ares, installed it for 4x4GB, and then the nightmare began.

The BIOS couldn't have cared less, aside from a POST message notifying that the memory configuration had changed and asking if I'd like to review the settings. Windows however was not at all happy. About 10 separate varieties of boot error messages greeted me as I cycled through an endless loop of BSODs, most before I hit the logon screen, and all before I managed to log on. Startup repair failed. Booting with safe mode worked, but sometimes only for a little while, and only if I did it without command prompt or networking. Oddly, I could use cmd inside of the recovery environment just fine. Sometimes it was the drivers that failed, other times a corrupted or missing kernel, or fwbf.sys, or 0xc000021a. No matter what, something went wrong.

Anywho, after I stuffed around trying to reinstall Windows (and stuffed up my MBR; had to revert to a 2-day-ago backup [always backup, kids]), I took out the new RAM. Booted up like a charm. Ran a memory diagnostic using mdsched. Took out the old RAM, put in the newly purchased RAM. Booted up just fine. Ran another memory diagnostic. Neither returned any errors. My rig runs fine on either set of 2x4GB but just doesn't like running the 4x4GB, regardless of being identical chips. Sidenote that MSI's BIOS liked running the 2x4GB kit at 1600MHz, but is happily forced up to 2133MHz on XMP Profile 2 on either set.

So what's your vote on why it went wrong?
    ■Your CPU doesn't like the 1.6V RAM x4
    ■Your CPU doesn't like the 2133MHz RAM x4
    ■Windows is to blame!
    ■Your Motherboard doesn't like the 2133MHz RAM x4
    ■Your Motherboard doesn't like you personally


And, where do you think I should go from here?
    ■Replace all that RAM
    ■Replace your Motherboard
    ■Replace your CPU
    ■Replace a combination
    ■Run all the RAM, but much more slowly
    ■Some godly option that doesn't require me spending a whoooollllle lot of money
    ■Light a fire in the woods, throw leaves into it, perform computations based on the number of leaves that do not burn


Questions welcome.

@Tradesman1: BIOS is the latest available. I've upped the CPU ratio to 41 of its 10K baseclock now, so it's 4.1GHz. Windows confirms. My sets are in DIMM 1 & 3 as per MSI's "dual channel" setup instructions. Set the two of them to 2133MHz and XMP 1 fine, but I couldn't find the [strike]droids[/strike] MC voltage you're asking for. Oddly, the in-OS control centre doesn't seem to reflect the 2133MHz, instead showing it as DDR3-1600 at 800MHz. About to restart and try adding the other two!

Progress! After the above, the BIOS failed (lots of times, after trying very earnestly to make the settings work). This time, with the OC settings, we didn't get to Windows, just the BIOS failed. No beepcodes or POST error messages. Most of the difference is, I suspect, the CPU ratio being brought up, seeing as the XMP and DDR frequencies were set the same the first time I installed all 4 RAM chips.

Mixing DRAM can be and often is problematic, there are no guarantees that mixed packages of DRAM will play, evenm of the same exact model. More in may article, part 2, Fiction, Item 2:

That being said, make sure you have the latest BIOS, will prob need a bit of an OC on the 3570K (4.1 or so) and try starting with one of the sets in slots 1-3 from CPU, enable XMP, select profile 1, then look for the MC (memory controller) voltage, think it's CPUVTT or DDRVTT and set it to about 1.15, save, exit, shutdown and try adding the other set in 2-4
