Hello everyone,
I've searched and found similar problems but no solution, really...
I just built a new system around the Crosshair V Formula-Z. Loving it so far, but I'm having an annoying RAM issue.
I got two 2x8GB Corsair Vengeance Pro sets of RAM. When I put them all in, the BIOS sees all four (although it doesn't automatically detect the speed):
But it only recognises 16GB rather than 32GB:
No matter which pair I put in which channel, it shows up like that. When I boot in to Windows it says the system has 32GB, but can only use 16GB.
I then found out that if I put RAM in channel 2, with no RAM in channel 1, it doesn't see it at all and the system won't boot (I don't know if that's normal or not).
I've tried this with all the settings on Auto, with forcing the RAM speed to the correct one (DDR2400), adjusting the RAM voltage to 1.65v, and adjusting the NB voltage to 1.25v.
No other adjustments or overclocking.
Motherboard has both 8pin and 4pin power connected.
Other than this issue, the system is 100% stable.
So... not sure if I'm missing something, or if it's a bad board, or what. Anyone have any ideas?
Relevant specs:
Board: Crosshair V Formula-Z motherboard, updated to latest BIOS.
RAM: Corsair Vengeance Pro CMY16GX3M2A2400C11R (x4)
CPU: AMD FX-9590
PSU: Seasonic SnowSilent 1050W
TIA!
