Which build of snap deploy for Dell Optiplex 760

I had an older version of snap deploy running that worked great with my Optiplex 755s. When I tried to use the boot disc on my 760s there was no network or hard drive support (lacking AHCI drivers I guess). Support told me to upgrade to 3292 which has been working, but is terribly slow. I've got 4 machines that have been loading images for the last 3 hours and they're not even 30% done. I never had this problem with my older version.

Does anyone know if version 3235 work with the 760s since that seems to be the latest build that actually works right?
