The manual says it can do it. But I've got 4x4GB Corsair XMS3 DDR3 dimms here. And if I install all 4 it fails to boot with the three beeps. If I remove the b channel it boots fine with 8GB of ram. Is this a known issue?
My old configuration is the same chips only 4x2GB Corsair XMS3 DDR3 and they worked great.
I have exactly the same motherboard & RAM chips (Corsair XMS3, 4x4GB set). After I first installed them, the computer worked perfectly fine for a month or so.
But last night my PC had shut down automatically and wouldn't boot, only did the triple-beep warning. After troubleshooting for a while, the situation is that if I put chips on the B channel, the machine will do the triple-beep-warning and won't boot.
I have the latest BIOS version installed, so I'm very confused. My PSU is a top-of-the-line Seasonic (Platinum 80 series) and I've monitored the voltages in BIOS - they seem to be all right. I don't do any overclocking or those sort of things, so I'm clueless. First it worked, now it doesn't. And there were no changes in hardware in between.
