The Mother Board

I am having issues with the RAM I bought...
First off its identical to what I already have installed..
I bought another 16GB (2x8GB) dual-channel kit... to boost my PC to 32GB, my motherboards max...

I have a ASUS Sabertooth 990FX r2.0 AND BIOS r2901 (2016), max RAM 32GB...

RAM = https://www.ebay.com/itm/332457582881
original bought from Amazon.com June 2016

after install...
I started it up and BIOS started saying there is only 8GB of RAM... out of the 32GB
it should have.. so defective memory? so to test that I removed the new RAM I bought from you and DAMN IT! its now showing ONLY 8GB of RAM

The BIOS DID detect all 4 RAM slots were FILLED when I had 4 in bought said all 8GB ..
WHY?! now even with my original 16GB still installed like before slot 1 and 3 for DUAL-Channel mode..
its not working right now.. only 8GB of 16GB
WHICH worked just fine before..
why?!


any help would be appreciated...

Switch off PC, remove power socket from mains, press and hold the power button in, release, take side off case, remove CMOS battery for a good few minutes. Replace CMOS battery, put PC back together, making sure the RAM is identical and power the machine back up. A good BIOS reset may resolve. Another thing to try is to knock the RAM timings back manually to a slower speed, that works sometimes as well..

did you keep your old battery or replace it (how old is it also)?

just more for curiosity I guess - but, if not replaced I would be wary of another episode reoccurring.
