My new(ish) Asus P8Z68-V PRO/GEN3 mobo only sees half of the 32GB RAM fitted and I'm not sure what to do about it. The BIOS sees only 16GB and therefore so does Windows. I've tried a couple of things, but it didn't fix it. Note that since I have the huge Noctua NH-D14 fitted I can't physically get to my RAM modules without pulling out the mobo, removing the backplate and fitting a standard cooler. It's ironic that the one problem I didn't want to get with this cooler, I did. Basically, I initially fitted 4 x 8GB Corsair Vengeance 1600MHz modules for 32GB total, before I bought the Noctua. However, I'd bought the high profile modules by mistake, so I bought two low profile versions of the same spec which allowed me to fit the cooler. To troubleshoot, I cleared the CMOS RAM by moving the jumper but that didn't help. I then went back one generation of BIOS from 3202 to 402, the one the mobo shipped with and that didn't help either. Running the 2700K CPU at stock didn't help either. Note that the modules are arranged internally as 2 banks of 4GB, so obviously the mobo is seeing only one bank. So, short of taking my PC to pieces and swapping sticks around (I still have the original Vengeance modules) I'm stuck, as there's not many configuration options available for RAM modules which would alter how much RAM is seen. And yes, I did try googling it. Please see my specs for full details of what's in my PC.
