** Summary changed: - [Hardy] 3 GiB od RAM make linux *slow* + [Hardy] 3 GiB of RAM make linux *slow*
** Description changed: Ubuntu Hardy v8.04.1 This is the hardware configuration: MB: ASUS P4C800-E Deluxe RAM: 4 modules of Kingston KVR400X72C3A (400 MHz, PC3200, DDR with ECC) Actual RAM banks configuration is with 2.5 GiB disposed this way: 1GiB 512MiB 1GiB and everything works fine. If I reach 3 GiB, placing the banks this way: 1GiB 512MiB 1GiB 512MiB (so Dual Channel works) everything is *really slow*. The system tooks 12 (twelve) minutes to load (from the disappearing of the grub splash) when normally it take 1'15". I tried a lot of parameters in the kernel line of menu.lst (irqpoll, noapic, acpi=off, etc., also mixed in various flavours) but anything has changed. I also tried to update-initramfs but it was unuseful. Also the single mode is slow and the Ubuntu liveCD *doesn't boot at all* (after some minutes it brings me to the busybox shell). The BIOS doesn't have any problem when the 3 GiB of RAM are installed, it sees all the banks with no issues and nor the Windows XP SP2 has any problem (it sees the 3 GiB and works with no problem at all); it was almost 9 months I hadn't to boot Windows.... this is really a sad day for me :( I have to underline that ALL the banks are from the same vendor, the same type and the same version (KVR400X72C3A), only sizes are different (1+1GiB and 512+512MiB). Please let me know something, I attached all the logs I can make to help your work, just tell me if you need something else. Thanks for all your work and for the effort you put in making Ubuntu better. + + Grub kernel line: kernel /vmlinuz-2.6.24-19-generic root=UUID + =46150dad-ee8f-4e44-863d-e5cd4bdff81e ro noquiet splash locale=it_IT + vga=0x305 acpi_osi="Linux" ** Description changed: Ubuntu Hardy v8.04.1 This is the hardware configuration: MB: ASUS P4C800-E Deluxe RAM: 4 modules of Kingston KVR400X72C3A (400 MHz, PC3200, DDR with ECC) Actual RAM banks configuration is with 2.5 GiB disposed this way: 1GiB 512MiB 1GiB and everything works fine.
