First i would like to know, what memory kits are you running clearly they are not same as mine, i thought the whole point of setting up a test is having the exact setup as the complainant, in this case not only me. I am using Corsair Vengeance Part Number: CML16GX3M2A1600C9 two kits to make it a total of 4 sticks and 32GB.
Plus i would like to know the XMP Version the kits you used have as all the people reporting memory issue like me have kits with Version XMP 1.3 regardless of the brand speed they have same issue as me Check the thread known as Memory Issues For DZ87KLT-75K, you will know its not only me.
Its clear that just running the XMP will not immediately cause the issues i have some times they appear sometimes not plus i have recently run recovery on the BIOS i don't know i it helped??? plus if you only restart the PC you will not spot any issue, it has to be shut down for a while at list for 5 minutes with no power from the wall remove the power cable from wall if necessary for the power to drain, then later on switch it on again after that, repeat the steps for at list 5 times and some times over 10 times and see what happens. either the 3beeps will appear and BIOS will forcefully reset to 1333 and on the BIOS 0446 the memory decrease might appear. the memory decrease i haven't seen for sometime now since writing this over 6 days ago.
