This worked for me! I have now got 2/4 slots working (previously only 1/4 was working!:@). I'm guessing that the other two slots will also work but will need a bit more rigorous cleaning. But currently am happy that I got at least one out of the three that were not detecting cards at all to function! Slot 2 seemed to be the problem.used flat piece of plastic like the guitar pick.it worked gigitty.was confused on whether the slot is bad, the ram stick, or both??reason for confusion there is that i tried the slot 2 ram in the 1 slot with slot 2 empty and no boot but slot 1 ram in 1 slot with slot 2 empty did work.now with both in.

Please note you may have to register before you can post: click the register link above to proceed. Follow these configuration rules when installing memory:. Slots 7 casino no deposit code. DIMMs must be added four at a time within the same group of DIMM slots; every fourth slot belongs to the same DIMM group. Each group used must have four identical capacity DIMMs installed (for example,four 256-Mbyte DIMMs, four 512-Mbyte DIMMs, or four 1-Gbyte DIMMs). If you can use a computer that’s in working condition that has the same RAM compatibility (the same DDR revision and a slot that can accept the capacity of the DIMM), swap the possibly faulty memory into the second computer and see if you encounter the same problems.

Dimm Slots 1 And 2 Not Working To Be

Hi guys,
I recently bought 3 more sticks of RAM (6GB) from Newegg to upgrade onto my computer. When I put one stick of RAM next to my currently installed stick, the computer won't display anything on the monitor and there is no beep from the internal speakers. So I mixed the RAM sticks up a bit, trying to see if any combination would work, and the finally I got it to work in the first and third RAM slot. I need help as to why I can't seem to add more RAM.
System Specs:
Mobo: ASUS M4A7TD-M evo
RAM: Crucial XMS 2GB DDR3 (X4)
OS: Windows 7 64-bit
Any help appreciated. Thanks.

Dimm Slots 1 And 2 Not Working Together

Hi all,
I have a bit of a problem with my motherboard's DIMM slots that I'm hoping you can help me get to the bottom of.
I recently installed a new CPU cooler (Noctua NH-D9L). Since installing it, DIMM slots B1 and B2 on my motherboard (ASUS Z270-AR) are causing POST failures. The system boots up fine as long as B1 and B2 are empty.
Tested all four of my RAM sticks (8GB Corsair LPX DDR4 3000) in A1+A2 slots and they all work fine.
When A1, A2, and B1 are filled, the POST State LEDs show CPU (red), followed by DRAM (green). When all four slots are filled, only DRAM (green) lights up.
During POST, I hit the MemOK! button on the motherboard. It ran through its tests and rebooted a few times, but still didn't successfully boot.
I've taken everything apart, re-seated all the components, and applied some air duster to the DIMM slots, CPU socket, and the underside of the CPU, suspecting some kind of contact issue. I even went as far as to carefully clean the DIMM slots and the underside of the motherboard with a toothbrush and a touch of isopropyl alcohol. No luck.
I'm worried I might have accidentally damaged something while installing the new cooler, but I could not see any damage to the CPU socket, nor the CPU itself, upon close inspection. The only other possible cause I can think of is the old backplate, which required a bit of force to remove from the underside of the board.
The CPU is an an Intel i7 7700K, in case that helps.
What do you think? Is my motherboard busted?
Cheers!
