So I've spent the past few hours trying to run a 256x256 texture pack for minecraft ( http://www.planetminecraft.com/...ture-pack/ ). I've looked all over the web trying to find an answer but no matter what I do the second i turn the texture pack on in the settings minecraft crashes and gives an error report about running out of memory. I've ran MCPatcher already. My computer has 8gb of ram and i've been trying to allocate 4gb to minecraft but it still won't run, I've even tried raising it to 6gb but no luck. I know it can't be my graphics card because I've just replaced it with a high-end nvidia geforce GTX 760 so i could play skyrim with decked out graphics. I've also tried allocating more ram to java after reading multiple solutions online but that did not help either. I'm pretty sure my Minecraft is running off of 64bit java though i have no way to be sure since i have both version on my computer. I was wondering if anybody could help fix this problem before i give up on this texture pack and try a few others. Here are a few pictures of my attempted solutions and crash report.
