I just mastered me a new system wirh ASUS DSBF-D Motherboard, 8 Gb mem and 64 bit WinXP. And the problem is that it goes not in standby mode. The monitor switches off but motherboard and everything else (fans, HDs) stays powered.

And another strange thing is that hibernation is also unavaliable. The system stays in so called "pae" mode and doesn't allows hibernation. Some sources to follow it's a particular WinXP-64 behaviour with more than 4Gb memory-

Any experience with problems like these?

what settings do you have set in the Bios?

Well, among other 100 settings the following may have attitude to the problem:

SATA is unpresent;
Native VGA display is disabled at hardware level;
CPU thermal management is enabled (tried with "disabled" as well — no result);
Memory brand mode — interleave (tried with "sequential" — no result) by the way tried also with "parallel mode" that makes only a half of memory visible to the system, ie 4 Gb, that didn't made hibernation avaliable anyway;
Plug&Play OS – no (tried with "yes" - no result);
ACPI Version — 3,0 (1 and 2 also supported, but the result is the same);
Poweron devices like mouse, keyboard and others are disabled.

Interesting is that updating BIOS to the version 1005 from current 1001 resulted in refusing to recognise the PCIE videocard with corresponding "beeping" error report "error in pci assignment" and something with vga settings at bios startup.
