SaraB123: I have been having a problem where the game will freeze every so often. I can hear the game running in the background, ie. if I push W I can here my avatar walk forward, etc. Seems to happen once just about every time I play. I use task manager to exit out of the game and it shows my memory use for the game at over 4500 MB each time. If I then restart the game, it plays pretty well for quite some time. I don't play for long periods anyway, because my laptop gets very hot, even with a good cooling pad.
alt3rn1ty: Your laptop getting very hot even with a cooling pad is probably a good indicator as to what is going on.
With laptops especially you need to know your machine can run the game and is at least ABOVE minimum specifications for the game (given on the GOG NMS Page), in ALL RESPECTS.
https://www.gog.com/game/no_mans_sky Tolerances for temperature inside the confined space of a laptop are not very good, if you are running a game and the machine is running hot all the time, its only a matter of time before things start going badly wrong = Freezes, Crashes, or worse the solder on the back of a CPU or GPU will heat up beyond its tolerances, expanding and contracting more than they are supposed to and melt / crack, leaving you with a dead machine and a very expensive fix.
Note also : When game devs provide the mimimum specifications for a Graphics card, they are talking about PC (ie Desktop PC) not Laptops. Desktop PC Graphics cards always have ..
Better cooling.
More pipelines
.. Than a Laptops Mobile Graphics card with the same model number.
So for NMS which requires at a minimum a dedicated graphics card NVidia GTX 480 or AMD Radeon 7870, you would need a Mobile Graphics card at least a couple of years newer than those models, for NVidia I wouldn't recommend anything less than an NVidia Geforce 970M with no less than 3gb VRAM (I dont know a good M model number for the AMD Radeon comparison). I used to have a 970M in an old laptop when I started playing NMS in 2016, with all settings low it would run a bit warmer than usual but not hot, but even then I was not happy so upgraded.
Right now I have an NVidia Geforce 1650, with 4gb VRAM, but even with that I have to restrict the game settings to use less than 4gb, and at a lower screen resolution than the game sets .. And with Hellogames advertising that newer versions of the game in the future (at time of writing) will benefit from having a card with DLSS support, I am thinking of upgrading to a laptop with an NVidia RTX 3080 with at least 6gb VRAM (the mobile version of which in a laptop will probably equate to something like a Desktop RTX 2060 - I havent looked into it in any great detail yet).
Anyway probably more info than you bargained for :) but I would seriously look into why your laptop is running very hot even with a cooler, more than likely this is a good contender for the source of your issues (without knowing more details about your machine spec we cant assume anything else at the moment), and I don't think your issue is related to the subject of this topic (the OP problem we can only assume was due to overclocking a desktop machine).
Edit: If your laptop has just an IGPU (Intel Integrated Graphics Processing Unit) and does not have a DGPU (Dedicated Graphics Processing Unit, like NVidia or AMD), your machine is woefully inadequate for running this game.
I just took a look at my graphics: I have an ROG rig (bought in 2018) with NVIDIA Gforce with GTX 1050 ti. So, probably at the lower end of decent. I do love laptops for their convenience and the fact that I can play in comfort instead of at a desk on an office chair (since I sit in one all day at work), but they are notoriously hard to clean the cat hair out of. I suppose since it's 3 years old I should probably upgrade to my 3rd Asus. *sigh*
