Hi all I am almost certain this is not a Suse issue, but I thought I might inquire just in case. As stated before, I have a Tyan K8W motherboard with 4Gb of DDR400 memory running Suse 9.0 AMD64 with the patch kernel. The BIOS registers 4Gb of memory, but the operating system only shows ~2.5 Gb of addressable memory (and starts swopping when it hits this limit). Any clue what is causing this? Since the Opteron memory controller is integral to the CPU, is this a fundamental problem with 244s or could it still be in the BIOS? Additionally, if I enable ECC in the BIOS I encounter unpredictable failures. How can this be? I thought Opterons ONLY work with registered ECC memory. Could BIOS settings be incompattible with the memory controller? Has anybody with a K8W updated to the 2885101i BIOS beta revision? Does it do any of the things it purports to fix: * Add DDR400 display support. * Add AMD Errata 86 fix * Open HT frequency options * Update CPU module to fix the CPU APIC Version error * Replace IORR with MTRR for AGP Aperture memory * Update Silicon Image Option ROM to version 5.0.31 (from tyan ) Thanks for your patience! Eugene PS. Thanks also to previous correspondents regarding the ATI driver issue (it doesnt yet exist for 64bit linux) _________________________________________________________________ Need info in a hurry?
