Sphax 512x512 crash

[Bluedragon]

I try to load sphax 512x512 resource of on minecraft 1.7.10 it freezes as it should do to apply the textures and then reverts back to the default, any help on this i saw that a few more people were having the same problem

Graphics card: Gtx 770 4G edition
RAM: 16GB DDR3

Screenshot of error attached

Update: it will work only without optifine, with optifine it displays default textures

Yea, you don't have enough resources to "fit" all the CTM textures.

Either assign more RAM or delete /assets/minecraft/mcpatcher/ctm/clay

If that doesn't work delete the entire ctm folder.
