So my 4GB boxes are actually 3.3GB boxes. Can't override it, says HP. They wouldn't refund 70% of the price of a 1GB stick, either. ;) I suspect what you're seeing is along the same lines; perhaps PCI hotplug or some other reservation that may be tweakable in the PowerEdge BIOS. Dell may or may not be able to help. FWIW; good luck, -- Ken. brownfld@irridia.com On Fri, Jan 25, 2002 at 12:05:10PM +1100, ivan wrote: | | Dear list users. | | My server detects less memory than it available. | | Available memory according to the BIOS 4049MB. | | System sees only 3.7GB ??? | Mem: 3799580K av, 1606816K used, 2192764K free, 468K shrd, 376972K buff | Swap: 8192992K av, 0K used, 8192992K free 1037532K cached | | | OS RedHat 2.7 standard kernel. | Linux atlas.es.usyd.edu.au 2.4.7-10smp #1 SMP Mon Dec 10 13:08:57 EST 2001 i686 unknown | | Hardware PowerEdge 4400. | ( supports 4GB ) | | Additional problem: | random crushes, trying to to find out why. | | Questions : 1) Any comments on why top only shows 3.7 Gb are welcome. | | | Thank you. | ================================================================================ | | Ivan Teliatnikov, | F05 David Edgeworth Building, | Department of Geology and Geophysics, | School of Geosciences, | University of Sydney, 2006 | Australia | | e-mail: ivan@es.usyd.edu.au | ph: 061-2-9351-2031 (w) | fax: 061-2-9351-0184 (w) | | =============================================================================== | | | - | To unsubscribe from this list: send the line "unsubscribe linux-kernel" in | the body of a message to majordomo@vger.kernel.org | More majordomo info at http://vger.kernel.org/majordomo-info.html | Please read the FAQ at http://www.tux.org/lkml/ - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
