Problems after upgrading ram from 2gb to 4gb
i bought 2x2gb kingston pc2-5300 cl5 200 pin sodimm, i want to upgrade my 2x1gb ram macbook.
When i put the new slots, the mac does not start, the display is black and the led is on as if the dispaly was in standby.
But if i put one of the new ram combined with an old one, the mac starts and the system profiler states that there are 3 gb ram and both the slots are OK.
In conclusion, there's no way to make the mac start without an old slot of ram, but both the new rams are working if used together with an old one.
My mac supports up to 4gb ram.
Is this a good question?
