Hi everyone,
I built a new computer :
Intel DX79TO
Intel core i7-3930K
4 x 8 GB Corsair Vengeance LP CML32GX3M4A1600C10 (1600MHz 10-10-10-27 1,50V 32 GB kit)
MSI Geforce GTX 660
PSU Corsair CX600
When I use three ram sticks in dimm 1, 2 and 3 or 4 to get 24 GB everything works fine. As soon as I use the four ram sticks (dimm 1,2,3,4) the system makes two unsuccessful boot attempts (few second then shutdown) and gets stuck on third attempt with memory error three long beeps, red led "high voltage in cpu circuits" blinking and code b9. I managed to boot few times successful on 32 GB by hitting the reset button, then the system works fine, even can restart, but on cold boot the error appears again.
Updated bios to latest version 0590. I tested each ram stick individually in dimm 1 with no error. Tested bios defaults and Xmp profile. Tested clear cmos. Tested swapping ram sticks, don't seams to be related to one specific dimm slot. I unmounted and remounted cpu to see if the socket pins or heat sink mounting were fine and no changes.
So i don't now if there is some faulty ram or motherboard or if this is a compatibility issue. Right now i could stay with system running fine on 24 GB but i need more memory on heavy 3D renderings, even planning to upgrade.
Thank you for feedback
