All eight DIMMS are same Corsair 2GB RAM modules (sorry, I think I wrote Kingston previously but is not true). Moreover, the modules are at 266MHz and not on 333MHz, the board would take only 6 modules at 333MHz. So lshw should report -2700 instead of -3200. Inspecting their serial numbers in the invoice I see: 340540434 340540435 330541284 330541283 330541282 330541281 330541280 330541279 Yes, 2 are different. I guess your question would be whether those 2 unseen DIMMS are the first two serial numbers ... I can't say now but definitely when only 8 GB of RAM are detected the problem would include additional two DIMMs. So, what would you recommend now. To flash from BIOS 1.20 to 1.50 and pray? ;-) Martin --------------020406020700060109010901 Content-Type: text/plain; name="lshw-12GB.txt" Content-Transfer-Encoding: 8bit Content-Disposition: inline;
