I know is late to be answering your question since was posted on early 2006. But I like to inform you and others that not to buy from fastmemoryman in ebay, or anywhere else online. They are fraud, and the feedback looks very good. I purchased a 1GB PC 2700 333 Mhz 184-Pin. My system board supports high and low density. The difference is the speed in your memory. Now back to purchasing the product from fastmemoryman. Shipment arrived and installed it. Turns out that when I checked my BIOS, it is only 32MB of memory. But the stick says 1GB and that is what I purchased for a 1GB not 32MB. Now fastmemory left a negative feedback stating that I purchased an incompatible memory chip. Well is not the compatibility, is that they send me a memory chip containing only 32MB, and printed 1GB.
