Sh*t...... just brought a A-Data 1GB ram for my PC this afternoon. Planned to install and make my PC run 2GB 1066Mhz at dual Channel...... but the new Ram I brought must be damage......
The moment I add it into the CORRECT coloured Ram slot, my PC can't start up..... remove it, the PC start normal. At 1st, thought that maybe some spec problem and can't run it in dual channel..... so try and run it at normal single channel. Same problem..... PC can't start

Remove my old 1GB Ram and install just the new ram into my system...... my PC failed to bootup again..... damn

Reinstall old 1GB Ram...... PC bootup without problem.....
Luckily the shop agree to exchange the ram tomorr. But like to know.....
How many of u here have ever brought 'Bad' Ram before. Not commonly do i hear got such problem.....
