Question Boot loop when coming out of sleep mode ?

Oct 19, 2021
Bought G. Skill16gb (8x2) 1333mhz ddr3 kit from ebay and it came in yesterday, upgrade from my 2 sticks of 4gb. Put them in slot 2 and 4 for dual channel and XMP to 1866mhz, worked perfectly from the start , used pc for a couple hours no problems, put it into sleep mode thinking I would be back on in the near future, went to bed instead and also work.

The Sleep LED was still blinking when I went to turn it on this morning. After a couple seconds it turned off and back on again, and continues to loop never hitting the bios. Now using only one of the new 8gb sticks in slot 2 works, putting both in or using the other 8gb stick results in more loops. Did sleep mode some how kill that ram stick or am I missing something? Any help would be great thanks!

Things I already tried:
  • Reseating ram multiple times and reseating CPU.
  • Loosened CPU cooler screws a bit(uncommon problem for dual channel not working)
  • Removed CMOS many times while switching various ram setups.
