My main workstation is a Core 2 Duo E6600 on an Intel BOXD975XBX2KR "Bad Axe 2". The machine has 2x1024 G.Skill DDR2-800 F2-6400PHU2-2GBHZ for RAM. RAM voltage is 2.16 V, CPU is stock voltage but overclocked to 3.0 GHz.
This rig has worked totally fine for months, generally being pushed pretty hard (running [email protected]
24x7, video encoding, running a virtual machine, etc).
Just today, I was surfing the web and it hard locked on me: no mouse, screen totally frozen, couldn't ping it, even the Num Lock key didn't do anything. I rebooted it, and it came back with a blank screen and three loud beeps. This is the BIOS error code for "No Memory". So I powered down, waited 30 seconds or so, then powered back on: same thing.
So I powered down, pulled the second RAM stick, powered on. The machine booted fine. I put the RAM back in: "No Memory" beep code. I then pulled the first stick, and put the second in its place. Booted fine. I put the second stick back in: booted correctly!
It's working, so I haven't tried swapping the RAM sticks back to their original configuration.
Does anyone have any idea what might have happened? I don't think I've ever run Memtest86+ on this RAM... maybe it's time to do that, eh?
Any thoughts are welcome!
