Hey johnstse12, did you ever get any help with your issue?johnstse12 date=1483481413 said:Hey guys I'm having problems with my G.Skill RAM and enabling XMP on my MSI Z170A Gaming M7 (Model #: F4-4000C19D-16GTZKW) Full Specs: Intel i7 6700k @ 4.4Ghz Noctua NH-D15 G.Skill 4000Mhz 16GB (CL19-21-21-41) MSI GTX 1080 Gaming X Samsung 840 EVO 500GB Windows 10 Pro Seasonic PRIME 850W If I set XMP 2.0 to on it won't boot and will say overclock failed. Manually configuring doesn't change the error. Can only boot with Memory Try It! set to Samsung 3433Mhz and HCI memtest will run w/o errors. Is it RMA time for the RAM?
This is extremely interesting. I have the z87-g45 motherboard with an i7-4770k CPU @ 3.50 GHz. I use this for audio editing and processing, not gaming. I have nothing overclocked. I had 2 sticks of G.Skill DDR3-2400 (16 GB total) and never had any issues. I added 2 more of the same sticks, and although I had no problems for a few months, I started getting intermittent freezes and shut-downs. When trying to power up, it would go into an infinite boot loop, not even making it to POST. After taking the RAM sticks out and reseating them it would start up every time and would go several weeks before the problem would return. Recently the problem became much more frequent, and started occurring several times a day. At that point I took it into a local repair shop and they said my CPU was running hot because the thermal paste was dried up. After that was fixed, I ran perfectly for about 2 days and the problem came back. So today I took out the extra 2 RAM sticks and left the original 2 in to see if It eliminates my issue. Based on this post that I quoted here, I probably should not have the DDR3-2400 sticks but the DDR3-1600 sticks instead if I want to max out my RAM at 32 GB. Does my problem sound like anything that type of G.skill RAM would cause or am I crazy?RemusM said:Intel does not guarantee anything above DDR3-1600 (or DDR3-1866 for a few models).
And finally, statistically (synthetic benchmarks, apps and games) speaking:
from DDR3-1333 to 1600: 4-5% boost
from DDR3-1600 to 1866: 2-3% boost
from DDR3-1866 to 2133: 1-2% boost
from DDR3-2133 to 2400: less than 1% boost plus all kind of stability issues.
The bottom line: 32GB DDR3-2400 is a waste of money for nothing but troubles.

Having overclocked RAM stresses out the IMC. Have more than 1 DIMM per channel stresses out the IMC. So its definitely possible that DDR3-2400 and 4 DIMMs (2 per channel) is not stable with your IMC.joewbrock date=1496015468 said:{Snip}
