For Span1shUk : The Kingston OEM memory that came with the Dell system is 2 x 1 GB configuration, p/n 1GB 2Rx8 PC2-6400U, but ther are four other number strings, some that could be meaningful to Kingston or Dell.
Update on Progress
Short term fix - Changed the memory around between the two systems !
Reinstalled the 2 x 1 GB memory back in the Dell system, Install the new memory from the Dell into the DB43LD board system. Ran a memory test using Memtest86 v3.4, no errors reported. Running the O.S. install, no more Blue Screens !
This new memory is from the Kingston Hyper-X line, size is 2 x 2 GB, 800 Mhz speed ( p/n KHX6400D2K2/4G). The Hyper-X line memory come with Heat Spreaders installed, so I can not check the memory chip configuration. Looking at the datasheet from Kingston, these Hyper-X DIMM have a chip component configuration of double-sided x16 chips, or each DIMM contains sixteen 128M x 8-bit chips. This is the one exception listed on Intel’s Supported Memory document. Could someone explain why one 16 chip DIMM fails while another 16 chip DIMM works ?
Called Kingston Tech Support, looking for an answer about the issue of using 1GB x 2 memory set. The part numbers did not match the ones that Kingston uses for what I would guess it be called their retail channel of products. I informed the customer rep. that the memory was orginally from a Dell system, and his reply was they do not support memory from a Dell. The two memory DIMM have a Kingston label attached.
In reading other posts, some have a simliar issue with memory installed on other Intel boards, where one DIMM works, but not two identical DIMMs.
Anyone with any thoughs on why some basic PC2-6400 memory would not work on an Intel board ?
