Hello, I recently purchased components to build a new pc. It works flawlessly (when it's working!) but has some strange Ram/power issues that I hoped I could gain some insight on. I have an Asus M5A97Pro motherboard, 2x4GB 1600 f-3 12800 gskill ram, AMD Phenom II x4 960T 3.0ghz CPU. My PSU is also 500 watts. I'm including a lot of info from other forum replies so hopefully you don't drown in the wall of text.
The OS is windows 7 64 bit. All of these components SHOULD be compatible according to manufacturer specs, however, when all 8 gigs of ram is installed in the reccommended (or any other DIMM slot) windows and the Bios only utilise half of it. In windows and the bios it acknowleges there is 8 gigs inserted and the brand etc, but insists only 4 gig is working. I have tested both sticks seperately and the Ram works fine by itself.
When I insert the ram into some other combinations the PC will not even reach the Bios while booting, and after putting back to a working configuration I get the message "overclock unsuccessful, press f1 to enter setup" before defaulting everything on the Bios again. I have the most up to date bios on the memory board and have already checked the CPU for bent pins/reinstalled it to rule that out.
Even with the "working" memory configuration (1 stick only) the pc can occasionally refuse to reach the bios upon booting. General opinion is that I need to change some "auto" settings in my bios to match the manufacturer spec of my ram, but I dont know how to do this.
I have tried in several configurations to rule out any bad slots or something. Either stick by itself in a blue slot works. Both sticks in blue slots work (half recognised) both sticks in black caused boot issues, and 1xblue 1xblack caused boot issues. It SEEMS as though the "auto settings" for the Ram in the Bios has the slots all configured differently and is trying to clock my ram as standard making it unstable or not work. It's the only thing I havnt been able to fully check myself as I dont know what I'm looking for to check ram timings, voltages etc.
When it fails to boot I have a red LED near the ram lit constantly. Successful boots have it blink only momentarily. Should a 500 watt PSU be able to handle all of my equipment properly? Have a sata 360 gig HDD 7800rpm, 1x PCIE Radeon HD5770 and the above hardware. Another user also suggested to check my Bios was set to 64 bit, which I wasn't even aware I could do. Is this a possibility?
If you could help at all I would greatly appreciate it. Thanks!
