[Chimera-users] chimera 1.11.2rc crashes

Hello again

In the Chimera specific benchmarks sheet, on the *Quadro K2000* line, under
the columns
*Main Memory* and *Driver Version* says: 24Gigs and 4.3.0, respectively.

Does that mean that it would be ideal to have 24G of RAM and the OpenGL
driver version 4.3.0?

Thank you
