128mb sdram shows as 64mb in Intel JN440BX
i am trying to restore a legacy system as follows:
OS: win98SE MB: intel JN440BX AA690874-405 CPU: Pentium II at 400Mhz with 100 Mhz bus Bios: just flashed latest - 4J4NB0X1.86A.0043.p20 Memory module: Microtech 128mb ECC double sided with 9 chips/side in slot 0 [pc100] chips a 0027 fff 5264805ETTA60 PC100-222-60 On boot, mem shows only 64mb checked config and sys does not force mem to only use 64mb Any ideas on how to get use of full 128mb? |

Sounds like the wrong type of memory to me. It's only reading one side:-( Have you checked the MoBo manual? Osprey |

Get http://www.belarc.com/free_download.html and/or http://www.aida32.hu/aida32.php and see if it is in fact being seen. |

From Intel: "The motherboard has three, dual inline memory module (DIMM) sockets. Minimum memory size is 16 MB; maximum memory size is 768 MB. The BIOS automatically detects memory type, size, and speed.

Memory size can vary between sockets. Note: BIOS revision P14 or later is required to support 256 MB DIMMs. The 256 MB DIMMs used with this board must be built with 128 Mbit device technology." ====================== I have BIOS P20 so that should not be an issue.. Unfortunately, I don't have another system that uses ecc ram so can't swap it to test. |

Unfortunately, I don't have another system that uses ecc ram so can't swap it to test. I'll garantee it's incorrect memory:-( Seen it many times. BTW if you put it in another machine that does NOT tell you anything! If it reports as 128mb in another machine, it does tell that the mem dimm is ok I think. It may not work on the Intel mobo perhaps but at least it would resolve it to being a system/bios/config issue rather than a defective part, wouldn't it? It depends on the MoBo chipset AND the memory chips etc. yes, and http://www.intel.com/support/motherb...0bx/jn_mem.htm shows that this mobo can use either ecc or non-ecc, single or double sided dimms. My mem brand is not listed, but it appears to meet the specs of the mobo as intel publishes the same, although the specs do change from doc to doc in Intels kb. 16M x 64 (128 MB) Unbuffered SDRAM Non-ECC - 100 MHz Micron Full MT16LSD1664AG-10CD4 Micron Full MT18LSDT1672AG-10EC7 Samsung Full KMM366S1724T-GL* Samsung Full M366S1724MT0-C1L00 16M x 72 (128 MB) Unbuffered SDRAM ECC - 100 MHz Micron Full MT9LST1672AG-10EB1 Samsung Full KMM374S1623BT-GL* Samsung Full KMM374S1623DT-GL* Samsung Full M374S1623CT0-C1L00 |

Buy the correct dimm. Go to www.crucial.com and use their Selector widget. They guarantee you will get the correct dimm... /daytripper |
