ou_ryperd Posted March 7, 2007 Report Share Posted March 7, 2007 Hi guys I have a problem that's driving me nuts... Running 2007 on a Compaq Presario 1600S. The laptop has 64M of RAM on-board and I just inserted a 256MB expansion chip. BIOS: System memory: 640 KB Extended memory: 326656 KB Windows: 320.0 MB the output from free: total 61132 KInfoCentre: Total physical: 62,599,168,bytes Harddrake: Socket 0: Installed size 64MB (Single-bank connection) Enabled size 64MB (Single-bank connection) Socket 1: Installed size 256MB (Single-bank connection) Enabled size 256MB (Single-bank connection) How do I get the kernel to see and use the extra 256MB ? I have tried the following in lilo.conf: append="mem=320M" append="mem=319M" append="mem-exactmap mem=640K@0 mem=319M@1M" append="mem=320@16M" and a few combinations thereof. What am I doing wrong ?

A quick google shows that your laptop will only support a maximum of 192 MB: http://configurator.memorystock.com/result...p;modelid=10925 Quote Link to comment Share on other sites More sharing options...
tyme Posted March 7, 2007 Report Share Posted March 7, 2007 apparently his BIOS picks it up, so technically it should be accessible (as is apparent in Windows, which recognizes all of it) - although most sites do seem to indicate a maximum of 192MB for this model of laptop.

Greg2 Posted March 7, 2007 Report Share Posted March 7, 2007 The HP support page also says “64 MB SyncDRAM, upgradable to 192 MB”: http://h10025.www1.hp.com/ewfrf/wc/documen...cname=c00045474 I'm sorry, but I can't explain what Windows recognizes? :huh: Quote Link to comment Share on other sites More sharing options...
tyme Posted March 7, 2007 Report Share Posted March 7, 2007 I'm sorry, but I can't explain what Windows recognizes? :huh:Like many other Windows oddities ;) My guess would be, based on this information, that for whatever reason having more than the officially supported amount of RAM might be causing..."oddities". It's always important to research how much RAM your system officially supports before buying any. Quote Link to comment Share on other sites More sharing options...
ou_ryperd Posted March 7, 2007 Author Report Share Posted March 7, 2007 I bought it because this type of RAM is very hard to get hold of - 133 pin SDRAM. I would have preferred 128MB, but 256 was all I could get. Well, Harddrake is also showing oddities then. Are you telling me that despite the fact that Harddrake sees the RAM, there's no way to get it to work ? Thanks anyway. Walter Kruse Quote Link to comment Share on other sites More sharing options...
ou_ryperd Posted March 8, 2007 Author Report Share Posted March 8, 2007 Thanks guys I returned the RAM and was refunded. I am now in the market for a 128MB chip ;-) Quote Link to comment Share on other sites More sharing options...
tyme Posted March 8, 2007 Report Share Posted March 8, 2007 Sorry we couldn't be of much more help. It's quite odd that your system would recognize more RAM than it officially supported, I've never seen a system do that before...but then I've never tried to give a system more RAM than was supported :lol: Quote Link to comment Share on other sites More sharing options...
