hi folks, I have late 2008 Mac Pro (3.1)
It has NVIDIA GeForce GTX 960 card, so I don't get the boot / diagnostics screen.
It was not booting up. The power light was flashing which I searched and found that to point to ram.
It has two ram cards with 16gb each which is not that old (may 2019) . They are good ram sticks with heat sinks, so when I pulled out one ram card out and it booted up. I tried the "faulty" card in both slots. Machine would not boot in either slot but the "good card" (16gb) would boot in either slot, so I figure the slots on the board are good.
now since the ram needs to be in pairs, how do you check to find if there is one faulty stick spoiling the whole series? or if its the board?
eg if I stick the "faulty" card in the empty slot with no ram, if the card is faulty would that stop the machine from booting? I thought power has to go through all the ram? so if there's nothing there, maybe it doesn't create a circuit? I don't know if that's how it works?
suggestion would be great thanks.
