How can i play with mods on my crap computer

[Slayerr555]

Okay so basically I'm running on a dell inspiron 570 slim from like 6yrs ago. I used to be able to run tekkit without too many issues. As of late I've been trying to run the yogscast moonquest modpack and I constantly get bad fps and just frame freezing every 2 seconds. My question is is there any way around this? I've allocated my 1G on the technic launcher and set all my graphics to be as basic as possible but I am still unable to run the moonquest modpack. Any suggestions? (Other than the obvious "get a new toaster")

You could try optifine.
