more ram with java 7?

[123nick]

is it possible to use java 7 with the increased ram options? i heard java 8 has a couple of rendering glitches, and on the modpack im using, with 404 mods , many a time a chunk will just never load.  i have all the optifine settings set to load chunks as fast as possible, or as efficiently as possible.  and yet still, there will be times were a big portion of land isnt being loaded. i tried -Xmx6G, but that didnt work. nor did -sms6G. any help?

400+ mods???

By the time it finishes loading, all the mods will have updated versions.... And the Sun will have burned out. 

You're lucky that occasional chunk loading problems is your biggest issue. 

Try fastcraft, if it's not in not in there somewhere. Or updated graphics drivers. Hard to troubleshoot such an immense pack.
