Suddently getting lots of errors

[Russ3r]

When i decided to install FTB on another computer than the one i currently use, i get a lot of errors in the console. When i try to enter a world, either SSP or SMP, Theres a lot of white boxes which i think is missing textures.
Heres the console:

When the FTB menu opens (with Singleplayer button etc.) the console keeps spamming:

@ Pre render
1281: invalid value
########## GL ERROR ##########

I have no idea what causes this, neither have i seen it before.
If someone could look at it, that would be great.

You are going to get that, and it's going to cause lag.
This is because you're trying to run a rightfully brutal mod pack on a 32 bit system, and are therefore limited to 1 GB of RAM (which is not enough)

So, some of the other packs should run just fine?

So, i've tried installing 64-bit Java, and setting the launchers "RAM maximum (mb)" to 3.75 GB.
Im still getting all the red text, and the white boxes.
I've tried to Force Update, but it doesnt change anything.
It might just be me thats messing stuff up, but its sad, suddently not being able to play FTB
