3 years ago I have the same issue on a MSI 1080, it will occasionally freak out and report anything between the real hash rate (33-34 MH/s) and 10GH/s. It seems to happen more overclocked than when the core is at stock clocks. I had some stability issues with the card, and still do, but it's much better without any overclock so I keep it like that with just the memory tweak, which unfortunately won't take any level of memory overclock reliably (it starts with +1000 mem off-set every 10 tries so I gave up on the extra 3 MH/s).
It's honestly the only card I have any problems with, the 3080's, 3070 ti's, 2070S's and even a GTX 970 is fine for months at a time. Meanwhile the 1080 is the redheaded stepchild of the bunch reporting crazy hash rates at times or crashing every 3-5 days requiring a rig reboot if I want to bring it back online, thankfully the whole rig doesn't crash.
The card doesn't have a temperature issue (water cooled core, memory has aftermarket heatsinks and fan cooling), it just seems to be what it is. Kind "good" to hear others are having this issue, I have not tested if this reporting insane hash rates is T-rex specific problem or if it happens with other miners.
The reported hash rate shows on the miner console and I can see it on the pool side as well in the history. Shares are not affected, so it doesn't seem to be a GPU crash in a sense, that is probably a separate issue (crashes every 3-5 days)
Snip from a test where I ran the 1080 with a 2070S on a separate rig for a while.

I don't know if this is a problem, but every time this happens I restart t-rex and it is then changed to more expected hashes Sometimes my GTX1080 card thinks it is crazy and runs at a couple of GH/s which does not make sense when everything else is running at MH/s. I am scared the 1080 will DIE or commit suicide if this happens and I miss it and do not restart the miner manually. As far as I know I am mining Ethereum to ethermine.org 1 card is not suppose to do this at a couple of GH/s You should see the spikes on the graph on ethermine.org every time this happens.
Below is a copy of the file that was generated before I restarted the miner. I don't know if you would require any other info apart from this. I am only a NOOB YouTube crypto miner, I only deleted my wallet address from the below and my rig name, I don't know if this could be used by anyone, LOL
Please help if you can.
