Listmates, I'm totally confused as to why my 10.3 x86_64 box is only using 3 out of 4 gig of memory. It was running 2 gig and I added 2 gig today. All four are good sticks of OCZ platinum DDR400 on the Gigabyte 8KE S2865 board with an Opteron 180 processor. I have other i586 10.3 boxes running and recognizing 4 gig with the big-smp kernel, but I was under the impression that the x86_64 default kernel could address up to 64 gig of memory. I have the latest kernel installed: 20:23 nirvana:~> uname -a Linux nirvana 2.6.22.19-0.1-default #1 SMP 2008-10-14 22:17:43 +0200 x86_64 x86_64 x86_64 GNU/Linux dmidecode shows the processor is PAE enabled and all 4 sticks of ram are there and recognized: Handle 0x0004, DMI type 4, 32 bytes Processor Information Socket Designation: Socket 939 Type: Central Processor Family: Athlon 64 Manufacturer: AMD ID: 32 0F 02 00 FF FB 8B 17 Signature: Family 15, Model 35, Stepping 2 Flags: FPU (Floating-point unit on-chip) VME (Virtual mode extension) DE (Debugging extension) PSE (Page size extension) TSC (Time stamp counter) MSR (Model specific registers) PAE (Physical address extension) <snip> (same on the other core) Handle 0x0006, DMI type 5, 24 bytes Memory Controller Information Error Detecting Method: 64-bit ECC Error Correcting Capabilities: None Supported Interleave: One-way Interleave Current Interleave: One-way Interleave Maximum Memory Module Size: 4096 MB Maximum Total Memory Size: 16384 MB Supported Speeds: 70 ns 60 ns 50 ns Supported Memory Types: Standard DIMM Memory Module Voltage: 2.9 V Associated Memory Slots: 4 0x0007 0x0008 0x0009 0x000A Enabled Error Correcting Capabilities: None Handle 0x0007, DMI type 6, 12 bytes Memory Module Information Socket Designation: A0 Bank Connections: 0 1 Current Speed: 5 ns Type: Unknown EDO Installed Size: 1024 MB (Double-bank Connection) Enabled Size: 1024 MB (Double-bank Connection) Error Status: OK Handle 0x0008, DMI type 6, 12 bytes Memory Module Information Socket Designation: A1 Bank Connections: 2 3 Current Speed: 5 ns Type: Unknown EDO Installed Size: 1024 MB (Double-bank Connection) Enabled Size: 1024 MB (Double-bank Connection) Error Status: OK Handle 0x0009, DMI type 6, 12 bytes Memory Module Information Socket Designation: A2 Bank Connections: 4 5 Current Speed: 5 ns Type: Unknown EDO Installed Size: 1024 MB (Double-bank Connection) Enabled Size: 1024 MB (Double-bank Connection) Error Status: OK Handle 0x000A, DMI type 6, 12 bytes Memory Module Information Socket Designation: A3 Bank Connections: 6 7 Current Speed: 5 ns Type: Unknown EDO Installed Size: 1024 MB (Double-bank Connection) Enabled Size: 1024 MB (Double-bank Connection) Error Status: OK But still 10.3 only wants to use 3 gig: 20:18 nirvana:~> free -tm total used free shared buffers cached Mem: 3276 1453 1822 0 51 899 -/+ buffers/cache: 502 2773 Swap: 2055 0 2055 Total: 5331 1453 3877 20:20 nirvana:~> cat /proc/meminfo MemTotal: 3354664 kB MemFree: 1864848 kB Buffers: 53148 kB Cached: 920880 kB SwapCached: 0 kB Active: 740912 kB Inactive: 547052 kB SwapTotal: 2104472 kB SwapFree: 2104472 kB Dirty: 44 kB Writeback: 0 kB AnonPages: 314084 kB Mapped: 98412 kB Slab: 120252 kB SReclaimable: 96900 kB SUnreclaim: 23352 kB PageTables: 19208 kB NFS_Unstable: 0 kB Bounce: 0 kB CommitLimit: 3781804 kB Committed_AS: 752300 kB VmallocTotal: 34359738367 kB VmallocUsed: 69720 kB VmallocChunk: 34359668219 kB HugePages_Total: 0 HugePages_Free: 0 HugePages_Rsvd: 0 Hugepagesize: 2048 kB So kernel and hardware gurus, how do I get my memory back on 10.3? Surely there is some switch or something that will let me use all of it isn't there? Thanks in advance for any help. -- David C. Rankin, J.D.,P.E.
