The ejector tabs came off? Never heard or seen that happen before. If you can get them back on, you will need to have the tabs fully open to seat the RAM. You will need to apply a good deal of pressure to seat the RAM. I found it to be a little more difficult than other boards that I had seen. Also, it is best to do the RAM before you install your video card. It seems like ABIT put the RAM to close to the AGP slot though I have seen that before. Another note, make sure you populate from DIMMs 4 to 1 or you will get an error. Lastly, if you are using WIN98 by chance, stick with 512mb or lower to avoid any problems. WIN98 has memory limitations, but can be adjusted to accept higher amounts, but not recommended IMHO. Good Luck!
