More ASUS fun
February 19th, 2008 by P. M. BarendtWell, I’ve given up on the P35 ASUS P5K Deluxe Wifi/AP, and I’m on to the ASUS Maximus Formula. The X38 is a bit more bearable, but the ASUS board still has the exact same issue with boots from time to time.
Working on memory timings, I got into the situation once again where the machine would not boot for over a day. Some people refer to the “DET DRAM” problem, or the “CPU INIT” issues with ASUS boards. Needless to say, there are serious problems with the way these boards handle RAM module. But, I tried clearing the CMOS manually with the switch on the rear panel of the motherboard.
Result: 2 types, when the “clr_cmos” DIP switch on the motherbard was set to off, the computer would power on and stay on, with the LCD display starting on “CPU INIT,” cycling to “DET DRAM,” and sticking at that point until power was removed from the power supply and the system drained its reserve charge (i.e. - the LCD diagnostic display did not ever cycle back to “CPU INIT” until power was drained from the motherboard). Secondy, if the clr_cmos DIP switch was set to on, the computer would boot, power sysem components, and then cycle off within about 3 seconds. Neither way would successfully boot.
What worked for me after two days this time was to reduce the system down to 1 single DIMM, and the system finally booted without issue. So, the first thing to do was to flash the BIOS, to version 0907. After the BIOS was flashed, the LCD poster cycled a few times - “CPU INIT, DET DRAM, CPU INIT, DET DRAM, CPU INIT, DET DRAM, VGA INIT,” and the damned thing finally posted properly again.
I have a *very* educated guess as to what the problem with all of these ASUS boards is: “ASUS Crash-Free BIOS.” The ASUS boot sequence is supposed to automatically detect when settings are messed up - memory timings, unstable CPU voltages and frequencies, etc. This is what also causes the machine, upon first boot or when BIOS settings are changed, to power system components, shut off power, and then power components again a second time for the real boot sequence. Well, sometimes, these ASUS boards get stuck, and either a.) never shut off during that sequence, or b.) get stuck in the first-boot mode, whereby they keep resetting, and resetting, and resetting, and resetting… all the while, your LCD poster indicates, “DET DRAM,” “DET DRAM, …”
This stuff really needs to get fixed, and soon. I really hope it can be with a BIOS update, as opposed to all of these problems that we’re having with these boards dooming them forever. I want this board to still work in 5 years, after all. I’ve got some media serving to do, and it’d be fantastic as a file server for a 10TB Raid array. But, probably not with Intel’s ICH9r, either… going to have to get a decent piece of equipment for job that important, I guess.
