the compatible NVIDIA Quadro 600 driver with Linux 5.6

Hello,

I need some recommendation on choosing the best graphic driver for my machin. Actually as I needed to work with a special fluid mechanics software I installed Red Hat Linux Enterprise 5.6 (not the last version of Red Hat Linux) and my graphic card is NVIDIA Quadro 600. Later I had Red Hat Linux 6.4 installed, and after trying to update the driver the system crashed and didn’t boot any more, so I thought it would be safer to first ask for some recommendation on the compatible driver with this version of Linux and then go for installing it to lessen the risk of previous problem. So I would be grateful if anyone could suggest a tested Nvidia driver on Linux 5.6.

Thanks.
