System failed to start after attempting to install an extra RAM Stick - Have I broke something?

[ANDREW GREEN]

So I put an extra stick of DDR4 8GB in the corresponding Dim slot. Initially it seemingly won't go deep enough. Restart PC and the BIOS can't see the new stick. Turn off and try again.

People say you need to apply decent pressure. So I do this time and I'm not sure it's deep enough or not. The motherboard bends slightly though. Now both slots in and I turn back on, it keeps coming on and off without reaching the option of going into BIOS.

I turn off the PC again, remove new RAM. Turn it back on, the exact same problem, it's turning on and off and not even getting to the motherboard front page.

Then power down for a few minutes sure I've bricked my system. Then it powers up and it's working now. Still wondering if I've done long term damage and wondering what happened.

EDIT current ram was overclocked in the BIOS to it's normal rating on the packet of 3000mhz.

Ok so after removing the small battery from the motherboards CMOS for 30 second, it now boots and works fine. I hate incompatibility. And it seems adding ram isn't always as simple as plug and play. Lesson learned

Hi mate,

Are the sticks the same model/brand? if not then they likely run using different timings, if so you may need to manually fiddle around with the speeds, voltages and timings to find a sweet spot that suits both modules...

They were the exact same part/speed/timings but I can only think the RAM in slot 1 had been set to run at a slightly higher speed meaning it wouldn't boot
