I didn't think it was possible for computer ram to retain programming after the power was removed. I bought a stick of ram off Ebay to put in the OPNSense firewall box I built earlier this year. The firewall has been running great for a few months now. The ram was one 4 GB stick of Nanya DDR3. The computer already had two sticks of 2 GB Nanya.
When I powered up, it hung. Forced it off and connected a monitor and keyboard. Powered up and its acting strange, very slow to post and when it gets to the OPNSense boot screen it freezes.
I thought it was bad/incompatable ram and pulled the "new" stick out. Powered up again and I see this:
Here's the Googel translation:
This screen would come up at every boot, before the hard drive began to boot. As if I were flashing the Bios. But the new ram was no longer in the computer. I removed the CMOS battery and unplugged the power cord for a few minutes. When I power up after that, the computer booted normally.
So, what's going on here?
