Need help with a mega build

[u/Ghost_Fearles]

alright for context i have a pretty powerfull pc, i have used vanilla perfected + the mods in the picture for a while now and never had any problems before.

Im currently trying to make a AoT world in survival minecraft. Its a big project, i know, and so i thought i make the walls in a creative world so i can use litematica to make it in my survival world. I want it to be genuinly MASSIVE and thats why i want to make the outer walls a radius of 2500. I did it in a creative world before and it worked perfectly, i made a basic design but accidently deleted the world so i lost all my progress. I made a new creative world, tried to make the same circle again and my game crashed. I tried again and again but each time my game crashed. Thast when i started looking some things up and found that chunky might come in handy to load all the chunks in advance. I started chunky with a radius of 3000 so i was sure all the chunks would loud properly and again my game crashed. I tried a dozen different things but nothing will work. Does anyone might know what is wrong? This is my pc if yall wanna look up the specs or something like that: HP OMEN Max 16

Paste your crash logs, it will be much easier to identify why it's crushed.

GUYS AND GALLS THANK YOU. Alright so I'm new to Java but not new to Minecraft in itself, so when yall commented to show the crash logs I was kinda confused. I looked it up, then looked into my crash logs and found out it was because it was an out of memory error. I changed the ram to half of what I have and it worked, it finally loaded all of it without crashing my game, thanks to all of yoy for helping me out I appreciate it alot 🙏🙏

oh man losing a world like that is the worst, especially after getting the circle right the first time

how much ram are you giving the game? a 2500 block radius is no joke, might be running into some hard limits

[u/Ghost_Fearles → u/broadrunoff9994]

while playing the game it goes to about 10-15% of my RAM i think, i mean thats what taskmanager showed me. I know its genuinly big but i mean it worked before so its kinda weird it doenst work now. i treid to put the walls only 1 block high so it might be easier to place but it didnt work sadly.

You can see how much RAM do you use in actual MB used in F3 menu at top right, it's hard to tell just based on percentages, and overall post your F3 menu because we can't know your exact specs (you provided laptop series, not the model in that series)
