Hello,
I am using an Asus p7p55 mobo with an i7 875k cpu and 6GB Corsair TR3X6G1600C8D 1600MHZ. I made sure to get the memory specified in the user manual. But it still will not boot, DIAG_DRAM turns on. When memOK! is held down DIAG_CPU leds alternates flashing with the DIAG_DRAM in the beginning when it reboots to test a new timing setting.
I have tried 3 sticks, 2 sticks in A1 and B1, then 1 stick tried in A1 then in B1. All had same issue. I installed the CPU in the right direction the heat sink is attached the not too much thermal paste and the fans are running.
There is power to the whole case including the GPU (EVGA GTX460) the fan turns on. The usb flash drive inserted (with the bios) flashes when power is turned on as well.
I have gone through this check list http://www.tomshardware.com/forum/261145-31-perform-steps-posting-boot-video-problems to make sure everything was correctly connected. Which led me here. There isn't much on trouble shooting this mobo that I have found. Please advise. Thanks
