Hello guys ! So i've got my hands on 2 power mac G5 recently, apparently dead : The first one would be this one : https://everymac.com/systems/apple/powermac_g5/specs/powermac_g5_2.0_dp.html Dual 2 ghz from june 2003 stamped powermac 7,2 and the second one : https://everymac.com/systems/apple/powermac_g5/specs/powermac_g5_2.0_dp_2.html which comes by the model number powermac 7,3. also Dual 2 ghz but from june 2004. Only difference is the "FX" at the end of the processor name : powerpc 970 FX for this one. They both have some trouble (not booting or freezing randomly) and i've found are VERY picky about a lot of things ! Anyway, to the point : i've come to believe that for the second one, the powermac 7,3, one of the two processor is rightfully in the blue (hence the freezing troubles.. already ordered new ram to be sure it's not that)... so i was wondering : Is it possible to put 2 x 2.3 Ghz (air cooled) inside this machine instead of the 2 x 2 GHZ. Found some on ebay but they are from the A1177 model. Will that be compatible with the screw scheme of the A1047 that i have ? My dual proc is with torx screws by the way (the one you're suppose not to put out the board) I've read some has done it without a problem... but ..you know... i prefer to be sure. Thanks guys. I may have a few others questions regarding sata upgrade and wifi compatible card (guess broadcom chip will do like the G4) but i'll start another thread for that in due time.
