Unsuccessful Installing MLNX_OFED_LINUX on RHEL5

I have a redhat server with OS version 5.11 and I’m unsuccessful in installing MLNX_OFED_LINUX-1.5.3-4.0.42-rhel5.10-x86_64. It fails because it does not support the OS version and when I try to build the modules for the kernel it still continues to fail. Any ideas what version works?

thank you
