i disassembled the computer to blow out dust and then i reassembled it. everything works only that the bios shows 18gb ram instead of 24 while cpu-z shows 24gb.
can it be fixed with a reseating of the cpu? or maybe take out all the ram sticks and try 1 and 1?
Highly doubtful this has anything to do with the CPU. Most likely one or more of the memory modules is not fully inserted. It currently is enough to be recognized but not fully functional.
i also applied new thermal paste. while doing that i noticed a thin white line along the outer plastic wall and the pins on the cpu socket
This is not a CPU problem, as previously noted. Possibly a BIOS reset is needed.
ok. how do i do a bios reset? i have now reseated the memory sticks and it now shows 16gb. im using the 3 most left slots and the last slot to the right. i have tried with all of the slots and those are the ones that work.
i'm using only the 4x4gb kit now. and from left to right the only slots that work is 1,2,3 and 8.

Memory slots are in pairs. Your motherboard vendor should have the information on what are pairs. e.g. if you had 4 slots, usually starting from the left, slot 1 and 3 are a pair and slots 2 and 4 are a pair. You should install memory in pairs in the correct slots.
DIMM_D1 and DIMM_D2 doesnt work at all. i tried putting a stick in D1 and it didnt boot. same with D2.
This is an X79 board so it is intended for quad channel memory. (Not required, but that gives the best performance in principle.)
m0nk3n: if you have mislaid the paper manual, I recommend downloading the PDF from ASUS USA
. That will show the allowed RAM configurations. I'm confused by how many DIMMs you have installed. Did you really have 12+16 GB showing up as 24 GB?
The Rampage IV Extreme has a BIOS reset button as part of the rear I/O panel. You don't have to open the case to clear the CMOS.
Good luck. I hope that the system isn't fubar.
i have the manual. it said to put in D1 first but it didnt boot. no, i had 16 + 8 gb ddr3 showing as 24gb :)
i have 4 sticks with 4gb 1866mhz ddr3 and 4 sticks with 2gb 1600mhz ddr3.
Groovy. If D1 is the slot recommended for placing a single DIMM, that's unfortunate.
If clearing the CMOS (also known as resetting the RTC) doesn't work, I'm out of ideas.
If you have somehow damaged or contaminated the LGA (land grid array) pins in the CPU socket, I can't advise you on how to fix it. Those (nominally) 2011 pins must be fragile.
