In that case, and if you are sure the GPU has enough memory the GPU might
just be broken. But, I would try updating the driver, even if the card is
not officially supported by the newer versions, it will likely work.
Away from that, why are you asking this on the VMD forum?

Betreff: AW: vmd-l: NAMD 2.11 Cuda does not work with Quadro FX 3800
Updating the driver is not an option: the Nvidia driver is 340.96. This is
the newest driver that supports the FX3800. Drivers of the 352.x series do
not support the cards.
On the system with the two Tesla K20 Cards, which is working, the driver
that is installed is 340.93. So the older driver with newer cards work.

I would suggest updating the Nvidia driver as 1st thing to try.

Betreff: vmd-l: NAMD 2.11 Cuda does not work with Quadro FX 3800
Hi,
yesterday I updated NAMD from 2.9 to 2.11. Unfortunately I got the following
Error when trying to run the CUDA enabled Binary on a System with two Quadro
FX3800 graphics cards:
FATAL ERROR: CUDA error binding lj table to texture on Pe 2 (ceo-01 device

Until NAMD 2.9 everything used to work fine.
Testing of NAMD 2.11 with CUDA on a system with two Tesla K20 Cards also
works.
System: Linux CentOS 7.2, Nvidia Driver 340.96,
Commandline for Testing (Lysozym-Tutorial): namd2 +idlepoll +p4
ubq_ws_eq.conf > ubq_ws_eq.p4.gpu.log
Graphics Cards: Two Nvidia Quadro FX3800
Something must have changed from 2.9 to 2.11 in CUDA Support? Someone any
hints?
Regards,
Joachim
