I'm looking to upgrade my IBM ThinkCentre S50 8183-32U;
Here is what I know:
333Mhz DDR SDRAM (PC2700)
184 pin DIMM sockets (2GB Max)
Non-ECC/Parity
Unbuffered
What I don't know is if the RAM that is compatible with this machine is High Density, Low Density, or both... Could someone please explain and fill me in? 
Please reference the following:

Oh come on! No one knows for sure? So far I have verified that low density memory will work, however I haven't verified high density yet. I've asked multiple webstores about the compatibility but the response is always either verifiying what I already know, or linking me to "IBM tested and compatible Memory" that they sell for 80% more money than normal memory. Ugh! What is this crap!?
