I have an old HP Proliant N40L; specs here (PDF). I'd like to increase the RAM to 8GB. Now I only have 2GB in one slot.
According to the specs I can install 2GB (1x2GB) Standard or 4GB (1x4GB)/8GB Maximum, using PC3-10600E DDR3 Unbuffered (UDIMM) ECC memory, operating at max. 800MHz
Is it possible to install 1x8GB with a higher speed? something like this?
Looking at the specs, no, you probably can't. It says right on page 3 of the spec sheet that the maximum supported RAM size is 4GB per slot. There is a slim chance that it might work anyways, since sometimes mainboards are capable of operating out of spec (and it's possible that there weren't any 8GB sticks when this manual was printed looking at this list), but I really wouldn't count on it.
