Good news and bad news. According to this, the chipset supports 8GB. However, it also says "256-Mb, 512-Mb, 1-Gb, and 2-Gb memory technologies supported". So if the motherboard had 4 RAM slots, maybe it would allow for 8GB, but since there are only 2 slots, maybe it only allows for 4GB. Though, again, I run into the possibility that the largest RAM of this type may have been 2GB when this document was created.
