Do you have "Hardware memory hole" or "Software > memory hole" enabled? Can use the full 8GB fine if you use "Failsafe > defaults"? If you use "Optimial defaults"? I am using BIOS version 1.0.2. Unfortunately, I've been unable to flash a newer BIOS; the procedure fails with an error indicating that the BIOS size did not mathc the image's size. This happens with all BIOS versions, including the one we are currently running. I'm waiting a reply from Tyan on this. These are the memory related BIOS settings. Advanced configuration: - 4GB memory adjust is set to auto (it can also be set to manual, in which case the hole size can be adjusted from 64MB - 2GB). - ACPI SRAT table is enabled - RSDT FADT revision 1 - HPET timer enabled - Halt on error yes - GART error reporting disabled Chipset configuration: - DRAM bank interleave auto - Node memory interleave disabled - ECC enabled - DRAM ECC enamble - ECC Scrub redirection enabled - 4 bit ECC enabled - DCACHE ECC ECC Scrub CPL disabled - L2 ECC Scrub Ctl disabled - DRAM ECC Scrub CPL 1.31 ms - Speculative TLB reload enabled In PCI configuration: - IO MMU enabled , size 256MB Thanks, Diomidis
