Is this cpu damaged?

[Nitrokanowbi]

7800x3d installed in an msi tomahawk b650. Worked (mostly, was never stable) for a few days (with most recent bios from msi) but as of today refused to boot even into bios.

As it was pretty unstable was planning on trying to figure that out and now today won't even get into bios! Feeling pretty frustrated by this, never had these issues before!

Red and fellow LEDs on the motherboard remain fully on. I've tried rebuilding the system, clearing cmos and redoing the bios but still no joy. When rebuilding I noticed these marks on the cpu, what do you think?

This.

And also check the motherboard CPU socket corresponding pins .

Thanks will get hold of some of that and give it a go. All pins are still straight as an arrow but will gentle dab then with the iso and clean the cpu.

So an update, cleaned the pads of the CPU with iso and then removed my second stick of ram and the gpu.

Booted and went into windows fine, but only on one stick and not the other and also not with both.

Faulty stick? Ram is Kingston fury renagade.

Did you put the ram back in the same slots as before?

Tried every combo of ram. Stick A in any slot works fine, stick B in any slot doesn't work at all and the same for using the two sticks, just won't get to bios if stick B is involved. Time to send the Ram back do you think?

Yeah faulty RAM stick. Annoying but atleast now you've learnt to test the easy things first before rebuilding the whole PC in the future

Very true! fingers crossed this solves the issue. This build is very frustrating so far! I just want a stable system to play games on in the few spare hours a week I get to do so!

So just to round off this thread for anyone else who might read this in the future, I replaced the RAM with Corsair Vengeance EXPO 32gb 6000mhz RAM and its all working as it should now, so looks like the issue was indeed a faulty stick of RAM.
