Question

Accidental heating a"Dead DDR2 ram stick"made it work!!!Does any one know why?Thanks in advance.

Answer 1

Accidental...like with an iron?
This is interesting...hard to believe.

Answer 2

@Dyliq: Please read the short true story about this!!! "My friend had a dead DDR2 ram stick with heat sinks .He decided to replace the Heat sinks by heating them by a soldering heater just to see Chipsets which were under the heat sink and the more he heated the less he could mange to separate and replace the heat sinks from the ram stick and gave up . By no means he put the ram stick in the appropriate slot (Stand alone say no other ram sticks.in the Motherboard installed)without any Idea of what would happen (Did it just for fun)and booted the PC and saw the boot up screen and the ramstick worked.

Answer 3

And you are positive that the DDR2 stick in question was not functioning prior to this? (It doesn't sound like he applied enough heat to destroy the transistor arrays or flip any bits.)

I only ask this because (some) RAM ICs are built to function properly WITH heatsinks. Without them, just the routine function would destroy them. So overheating is certainly not going to fix it, and even barely exceeding the max rating can damage them.

Answer 4

@Dyliq:
Yes the DDR2 Ram stick was dead and my friend was certain about this.

RE: "Heating " I agree with you but as far as I can remember In the Golden Days of PCs I mean when DOS was the emperor I Read a book named "Upgrading and Repairing PCs,BY Scott Mueller" in which it was pointed out that some times you need to heet some Electronic components to recover and make them function.so it is not hard to believe so.(While I believe Heat is the enemy of Electronics.

Answer 5

If you are heating with a soldering iron, then there is a chance that you remelted some solder. If there were any bad solder joints, perhaps this fixed them.
