Question Very odd RAM behavior

Hello,

I am currently running an i3-7350k (stock settings) on a Z270-D3H motherboard with an 8GB Corsair Vengeance LPX kit (CMK8GX4M2B3000C15). While it is a second-hand machine, it has not been used for too long, nor was it abused or neglected. The RAM worked flawlessly for him, as it did for me, for months, until one day, when I turned on my computer, it began to boot loop. I've resolved it in the past, leading me to disable the profile to ascertain whether or not XMP was at fault, and it has not appeared for a while - until but a few days ago, when it became recurrent. At times it would not post with both sticks even with XMP disabled, and sometimes enabling it was more stable than without it!

If it is any correlation, I had not updated Windows 10 since procuring the machine in early January, and only 2 days ago had I re-enabled updates and gone through the process. Once I did though, the problems only exacerbated, as it began to BSOD for the first time: IRQL_NOT_LESS_OR_EQUAL and KERNEL_MODE_HEAP_CORRUPTION among them.

I am at a loss as to what to do since I've never encountered RAM having difficulties running at their barest nominal specifications. Could the IMC not getting enough voltage? Is 1.2v too low for this particular set of mine?

I know it can run at 1.35v in its XMP profile, but the default runs at 1.2v and I wondered if that was not enough. I've made a USB drive of memtest and run the test promptly.

I've completed the memtest with the memory running at its 3000/C15 XMP profile, but I've upped the voltage to 1.36, and not a single error was found. Will report back if anything changes...
