Can You Reuse Ram Sticks. The problem is that usually by the time one has upgraded the type of ram slots change so it may not be usable. The best answer I can give you comes from here.
As long as the old RAM has the same timings and is the same voltage it will work OK. You can use just about any paint you like just dont use too much. Yes you can buy a identical single stick and install it.
RAM sticks dont even overheat until they hit 188F.
And even if it fits it speed may be clocked slower than the ram that comes with your new computer and causing it to retard overall performance. Youd have to use a much higher temp if you hope to reflow the solder. For example rather than keep the pair of 4GB sticks I. Typical 6040 solder melts at 370F.
