i had a 1.0x bh6 that i recently breathed new life into it. my manual says that it can run a maximum of 384mb of ram, but after flashing to the ss bios i was able to run a 256, and 2 128s of pc 100 for a total of 512 with no problems. i tried running it with the 256, a 256 of 133 and one of the 128s but it wouldnt recongnize over 512. it is also now running a p3 650 and waiting on 2 200gig seagates.
