my motherboard has stopped detecting all sticks 4x8gb. 32gb total.

the max detected is 16gb no matter how i juggle them around in the slots

have tested each slot and stick and they work just fine in set of 2 but not when all 4 are being used

system worked great for the last 4 years or so and recently just stopped on a reboot

 

any input??

Try to re-seat the RAM if it is not solving the problem try with the CPU.

I've seen that happen before. In most cases it's a lack of sufficiently clean power to the memory. Unfortunately the memory power comes from the CPU through the motherboard, so it may not be fixable without replacing the board. You can try a power supply, but that didn't help in the cases I saw.

Unfortunately in the instances I've seen, it wasn't the system PSU, it was the power regulation on the motherboard itself.

I did some tests in the past with the G.Skill Ripjaws on my Asrock B75 Pro3-M and found out that this RAMs are not really stable on this board.

Maybe change the RAMs to Crucial or Corsair (only for testing) and see what happens - i use 4x4 GB Crucial Ballistix Sport and they work fine.

Also possible that the CPU/MB have some problems... i would rule out the PSU.

Wait, so did 4 sticks work BEFORE the CPU change?

no. they stopped working before. as i was reseating everything i took the chance and upgraded cpu.

i think its safe to rule out cpu and psu. only leaves mobo or ram sticks.

UPDATE:

finally replaced my b75 board for a z77 and im back to 100%

 

thanks guys for your input
