|Dear Tubesandwires, Thank you very much for your reply, especially so as you seem to have done a bit of research before answering. This is much appreciated.|
I also saw that thing in the specs about max 1GB per slot. But as this is demostrably untrue I am still left with a nagging feeling the 2GB limit might be equally untrue.
As I already said above, CONTRARY to the official specifications and CONTRARY to the sources you mention, it works perfectly well with 2GB memory in one of the slots (in either one of them) and it comes up with 2GB recognised. (It does, I swear!)
Doesn't this indicate that the mboard wiring would be OK for up to 4 GB ?
What you say about the chipset being limited to max 2GB might be an explanation though. Perhaps I need to dig into that side of things a little deeper.
With both memory chips installed, the laptop is just dead. Not even the BIOS starts up. So no, it is not a case of recongising half of each.
Yes, I am aware that only approx 3,4 GB are available under 32-bit OS's but this should still make a big difference compared to 2GB when there are many big apps up and running. On XP I frequently have a couple of browser windows with maybe a dozen tabs open including video contents, one or sometimes two virtual machines running under vmware, an office app or two (word, excel, powerpoint), maybe the netbeans IDE and a couple other bits and pieces. It's hard to believe a 70 per cent increase in memory from 2 to 3,4 GB would make no difference in that situation.
Incidentally I recently upped from 1GB to 2 GB on another machine and saw a DRAMATIC increase in performance and responsiveness under XP. Apparently I don't qualify as a member of that exclusive "most people" bunch you are referring to :o).
Again, thank you very much for your time. Any further input on this will be much appreciated.
