Hi there, I have a dual-opteron with 8GB of ramm installed (8x1GB dimms) on a Tyan K8W (S2885). But linux only uses 7.3 Gb... Linux on boot detects correctly the available 8Gb:
[EMAIL PROTECTED] ~> dmesg|grep -i mem Node 0 MemBase 0000000000000000 Limit 00000000ffffffff Node 1 MemBase 0000000100000000 Limit 00000001ffffffff Bootmem setup node 0 0000000000000000-00000000ffffffff Bootmem setup node 1 0000000100000000-00000001ffffffff HighMem zone: 0 pages, LIFO batch:1 HighMem zone: 0 pages, LIFO batch:1 Memory: 7391892k/8388608k available (2655k kernel code, 0k reserved, 700k data, 200k init) agpgart: Maximum main memory to use for agp memory: 7956M Freeing unused kernel memory: 200k freed ohci_hcd 0000:03:00.0: irq 19, pci mem 0xfc8fd000 ohci_hcd 0000:03:00.1: irq 19, pci mem 0xfc8fe000 Note: Memory: 7391892k/8388608k available (2655k kernel code, 0k reserved, 700k data, 200k init) Now, I've seen that this unused memory is related to pci && AGP dma maps.. But, on my sparc I also have PCI and I don't have these problems (4gb real, 4gb used..) And on dual-opterons with 8GB from HP (rack 1u, don't recall model name) I also have 4Gb real, and 4Gb being used. So, does anyone know how to make this system really use the 8GB of ram.. Having 700MB of fast ram being unusable isn't very to my taste... -- Miguel Sousa Filipe -- [email protected] mailing list
