Learn English – Gerund as a noun ‘having/taking a shower’

Consider the following:

There was no scaling that steep cliff.

Going around the mountain was the sane choice, not scaling that steep cliff.

The first means that the cliff was impossible to scale. The second simply refers to the action of scaling as a non-choice, a thing that exists but which is rejected.

There was no reasoning with them.

It was impossible to reason with them.

no + the -ing form denies the very existence of the -ing nominal.

It is used with existential statements.

not + the -ing form accepts the existence of the -ing nominal, but negates its presence here (in this context).

He said he liked fishing, not hunting.

He thought fishing was acceptable, but said there should be no hunting.

He did not see them off:

His not seeing them off on their journey made them sad.

It was impossible to see them off:

He was in another country on a business trip. There was no seeing them off.

The difference becomes clearer when you use different verbs but the same formation:

"I regretted having programmed the doomsday device"

"I regret programming the doomsday device"

In the first the regret is in the past, it might be possible to infer that the writer still regrets programming the doomsday device from context, but that is not explicitly made clear in the sentence. In the second the regret it current.

In your example, when reporting that you previously remembered something you cannot help but remember that thing now and to state that you remember something now you must've have remembered it previously (even if it was just the instant before you spoke), so there isn't a real distinction in the meaning. However your first sentence has a literary tone, i.e. a writer may chose the first sentence over the second, whereas the first is more everyday language. I would always use the second sentence in speech as the first may come across as ever-so-slightly pretentious to some listeners.
