In your screenshot there is a whitespace in the userpath, sometimes Winrar can be a bit fussy about that. Have you tried to copy the rar file to a directory without spaces in its name like "C:\Benchmarks"?

It seems like you fixed it :-)

Arch Linux? ... is that allowed in Competitions?

Was that run on Windows 10 ?

You could try to set up a Dual-Boot system with your Windows 10 installation and a clean Windows 7 with nothing more than drivers and OC-Tools. Maybe there is some free space (60GB should be enough) on your disk, so that you could shrink an existing partition and install Windows 7 in a new partition, or you could get a small SSD (~120gb) to install Windows 7 on.

I'm pretty sure, you meant memory frequency, not reference frequency...
