Hi All, I got a Dell Precision Workstation 370 with 4GB memory, RHEL4 Update 2 and Pentium4 Hyperthreading turned on. In BIOS I can see total 4GB memory correctly. But when I booted intoo RHEL, I can only see 3GB total memory: [shrek@integrin downloads]$ free total used free shared buffers cached Mem: 3113776 1548608 1565168 0 35508 1190132 -/+ buffers/cache: 322968 2790808 Swap: 2096472 0 2096472 and [shrek@integrin downloads]$ cat /proc/meminfo MemTotal: 3113776 kB MemFree: 1562912 kB Buffers: 35672 kB Cached: 1190488 kB SwapCached: 0 kB Active: 1043660 kB Inactive: 422760 kB HighTotal: 2226728 kB HighFree: 758144 kB LowTotal: 887048 kB LowFree: 804768 kB SwapTotal: 2096472 kB SwapFree: 2096472 kB Dirty: 160 kB Writeback: 0 kB Mapped: 828140 kB Slab: 36700 kB Committed_AS: 748784 kB PageTables: 7708 kB VmallocTotal: 106488 kB VmallocUsed: 42084 kB VmallocChunk: 61940 kB HugePages_Total: 0 HugePages_Free: 0 Hugepagesize: 2048 kB I tried both kernel versions: kernel-smp-2.6.9-22.EL and kernel-hugemem-2.6.9-22.EL, all of them can only see 3GB memory. How to solve this problem so that I can see 4GB total memory on my system? Thanks a lot! __________________________________ Yahoo! Music Unlimited Access over 1 million songs.
