So I have a machine I built from old parts that I just stuck Redhat 9 on, and I'm running into a strange issue. At first I simply didn't have enough memory to run RH with the full GUI, and I sure as heck am not well enough versed in Linux to run a strictly command line installation. So I set the machine aside until I could get more memory...

...which is now. I purchased a 128mb SDRAM stick and stuck it in. I also have some older sticks, but I have no idea how much memory they have, as none of them are marked (I just know not a lot, 64mb each at most). I had an extra slot, so I also stuck in one of those sticks.

So I just brought the machine back online and installed a totally fresh RH 9 on it, GUI and all no problemo. However, it's running slow as Christmas. So then I see that according to system settings, it thinks it's only running on 64mb of RAM. I'm presuming that must be the old stick, but I have that new 128mb stick firmly placed in the first SDRAM slot.

So what could be the cause of this?
