The old motherboard was killed in a flashing gone array incident.
Picked up new RAM today, no luck, same beep code.
Hoping it is not my GPU (just bought 3 weeks ago)
Do you mean it was killed while flashing the BIOS? If so, then do try with another PSU. There's also a reason for any kind of incidents, and any electric instability is poison for flashing.
After that, if you still get the same beeps, remove the GPU. If you don't have
any replacement handy, try to boot without it to hear if the beeps are different. Actually, it would be good to unplug all devices, leaving only the processor and one stick of RAM and a known good GPU when trying to find the reason of the beeping. No hard disks, opticals, nothing. Only the motherboard, PSU, GPU and one memory module at a time. If you have fitting spare parts, try them. When you can boot to POST, you can add a module, one at a time and reboot.
Remember, for troubleshooting purposes the spares don't have to be exact equivalents with your original setup. Any matching component will do, because you're only going to boot the rig, not play games. Even a decade old PCI video card would do for checking, if the problem lies in your GPU or it's slot or power.
