IE7 Regedit for Vistax64

Well as the title suggests i need help with a regedit for IE7 for 64-bit Windows Vista Ultimate. I just need to know what sub-path and datakeys i need to enter to increase my Max Connections/max connections per server. I found the sub path i used on ie7 in xp but when i did it in vista it changes didnt stay in effect after my restart. Im sure it was prolly just a bad restart but if someone can post, or link vista64 specifics to me id appreciate the help.
