    DP55WB with 16GB ram?


      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.

          Thought I was running the most recent BIOS but I wasn't.  Updated to most recent and works fine now.

            Hi there,


            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.


            All help highly appreciated! Thanks!

              One of the Ram chips may have died try them one at a time see what you get , use the first socket nearest the CPU .  KUDOS on the Seasonic , thats the only CO. I use for PSUs.
