Hi all, new user here. I have a Jetway V266B motherboard. I've just added a 1GB PC2100 DDR 266Mhz stick into it but it is reading it as 512MB. The spec of the motherboard can be found here: http://220.127.116.11/search?hl=en&s.../product/amd/v266b/spec.htm&btnG=Search&meta= I have recently flash the BIOS but this hasn't made any difference. It reads 512MB on the BIOS screen and on the Windows XP OS. Is this a problem with the memory (not being compatiable) or can is it just a setting on the system I have to adjust to read it? If you have the time, the motherboard manual can also be found here: http://18.104.22.168/temp/jetway0c/downloads/manual/V266BR4A.zip Every help is appreciated.
