Skyrim is a 32-bit program meaning that it has a mod limit of 3.1 gb memory limit, meaning that if you go beyond that (You can get a skyrim ram monitor) you'll crash, no matter what computer you've got. As long as everyone has at least 4. gb of available ram you could run up to 200 mods or something like that as long as they don't go beyond 3.1 gb in one frame. The most important thing is that you turn of background programs on your computer that might interfere with Skyrim, SKSE or NMM. But the most important thing is that your load order is set correctly, you can use LOOt and TES5Edit for that. LOOT: A tool used to set the correct load order and giving warnings, such as displaying if mods need cleaning, patches, updates etc. TES5Edit: A tool used to clean mods, solve conflicts, make patches etc. Advanced program, be careful! My computer is as old as the first Iphone released: Specs: Windows 7 Ultimate Intel Dual core 2 E7400 2.80 Ghz. 4,00 Gb RAM. 32-bit system. AMD Radeon HD 6670 And I can run about 180 mods, a lot of light mods and a few heavy ones like Falskaar and Wyrmstooth. I use no texture or visual mods because it's what uses most RAM.
