MacBook Pro 11,3 retina crashes - NVRAM setting to increase refresh rate?

[Camicia]

It has been happening for 2 months or so.

I though it was a heat related problem. I changed the thermal paste on the CPU and GPU. Heat seems to make the crashes more frequent but it happens when it is cold, too.

I tried to reinstall the OS. Now it runs a lot cooler but it still freeze every now and then.
A MemTest reported once a RAM problem but I was not able to reproduce it.
The Apple Hardware test also report a problem with the ram once but then not anymore.

I wonder if there is a way to make more frequent the memory refresh cycle ( https://en.wikipedia.org/wiki/Memory_refresh ) with a NVRAM setting or something.
Maybe a way to mark a region of the ram as bad so the Mac OS X does not use it.

Or do you have any other suggestions that can help (beside getting a new laptop)?

Finally this: https://apple.stackexchange.com/questions/306714/macbook-pro-15-retina-mid-2014-random-shutdowns that point to https://apple.stackexchange.com/questions/306714/macbook-pro-15-retina-mid-2014-random-shutdowns

I am going to give it a try.
