I have a Risc PC 600 with 1 MB VRAM. I want to change it with a 2 MB VRAM Module. But I don't know how to remove the module because there is a strange white lock bar: http://www.kharchi.eu/files/VRAM-RPC.JPG
I have tried pull the bar to top but it is _unmovable_. I don't think I need violence to move it because the mainboard could break.

Believe it or not, you need to pull harder - straight up preferably. I have snapped these in the past, but it should still hold the new one firmly if you do. You may care to try with needle nose pliers.

Try just pushing them outwards, they rotate around the base of the side pillar - it's a standard DIMM-type socket with locking clips, as is plain from your picture (never taken a PC apart?).

No, it's definitely not. The normal RAM is a standard socket, but the VRAM socket is not. The VRAM socket doesn't have rotating clips - the black part of the socket is all one piece.

No, the VRAM socket is different, it doesn't slot it, fold and cli[p like DIMM, but is just inserted and removed vertically. Some force may be required to remove it.

Some early third party VRAM used a thicker PCB (IIRC Simtec) that required you lean on it with most of your weight to insert. Removal also therefore required a lot of effort.
Even on standard thickness modules the little plastic pull up clip never felt is was strong enough to use.
Fortunatly pulling up with one hand whilst holding the PCB down with the other has never damaged anything that I've heard of!

Thank you!
It works now, if I push the VRAM down and pull the white lock bar at the same time.
