kurisukun Posted March 24, 2009 Share Posted March 24, 2009 i just have put together an AM2+ based AMD Phenom hackintosh. with iDeneb 1.4 the install went all smooth and it runs fine. am thinking of selling the mac pro now. but, there is one big question: will i be able to upgrade my AMD Phenom hackintosh to 8 GB of Ram? leopard only runs in 32Bit mode for amd cpus (except with -force64 flag on startup, which isn't really an option, as many older apps won't work then) anybody tried running an AMD based hackintosh (32Bit) with more than 4 GB of RAM? to be honest, i dont wanna hear if someone just thinks it will work or not. i've read countless such threads already. i want to hear what you guys know after trying it out yourselves. my hackintosh runs absolutely perfect (after minimal patching even including sound, lan and everything) on 4 GB ram, which is just not enough for a heavy multitasker. geekbench 32bit result is even a notch better than 2006 macpro 2.66 quad! - AMD Phenom II 920 - Asus M3A78-T - 8800 GTX - Velociraptor 300GB - so far 4 GB DDR2, i really need more or need to switch back to macpro Link to comment https://www.insanelymac.com/forum/topic/158935-8-gb-ram-in-32-bit/ Share on other sites More sharing options...
MacProUser83 Posted March 24, 2009 Share Posted March 24, 2009 a 32 bit environment is not able to address memory over 4Gbs... I dont know if with PAE it will work.... but my short answer would be NO u wont be able to. the limit is given by 2 to the power of 32 = 4 294 967 296 bytes.... and that my friend is 4Gb.... so... ohh and btw... if u r running a 32 bit mode those 4GB are the total memory supported so u will have to substract your video memory from the available 4gbs ... so if ur gtx is the 768mb model u will end up with with like... mmm 3.25 gb of wired ram... or something like that.
