Okay so I'm about to throw this thing out the window. My parents have an old K7T 266 motherboard with a 1.4 GHz Athlon processor. I just got home, and they want me to do some upgrades to make it run better. I check it out, and it only has 256 MB of ram. We buy more, I install it, and the system doesn't recognize it.
I am simply trying to add another 256MB for 512 total, but the system only recognizes the old stick of ram. The manual that comes with my mobo offers no special instructions for installing memory (e.g. no special sequences that they must go in). The new stick of ram I bought is PC2700/PC2100, so it can run on either a 266 or 333 MHz bus speed, but the added memory is not being recognized at all.
-buying two different sticks of DDR ram
-installed them in every possible combination alone and with the old stick
-reading the manual
-kicking my cat
The old ram is simply 256MB ddr pc 2100 266MHz, and has memory modules built onto both sides. It's some generic brand, and doesn't say what it is on the stick.
The new brand is something I quickly picked up from staples, 256MB of PC2700/PC2100 (333/266). I dont know if it is significant but it says 'DDR DT' on the package.
I'm really not sure why this system isn't recognizing the ram, it isn't supposed to be this much of a headache.
Any input will yield genuine affection.
