Ok, a symptom often seen with a mixture of old/new SDRAM-components and chipsets. In old days, there were different organisation of modules possible. 2bank/4bank modules appeared. Also the chip size organization has become bigger, with the new 64 MBit chips available. Back in VX days it was different. So the mobo simply recognized the stick as 1/4th as big as it really is. Same symptoms you see in old 486 boards if you pop in a 8-chip module of PS/2 RAM- they tell you that they only see 4 MB of it, due to different bank organisation. Try flashing a new BIOS, sometimes it will help, otherwise get another (older, PC66) stick of RAM or a new board... ;-( Regards Olaf Hoyer=20 - - - - - - - -=20 Olaf Hoyer ICQ: 22838075 mailto: Olaf.Hoyer@nightfire.de home: www.nightfire.de (The home of the burning CPU) Wer mit Ungeheuern k=E4mpft, mag zusehn,=20 da=DF er nicht dabei zum Ungeheuer wird.
