ASUS P5W DH - Problems + Fixes Thread

**lawrywild** · 08-06-2006, 06:18 AM

Well, considering lots of people are having quite a few problems overclocking on this board recently, I thought it'd be a good idea to start this thread. I'll update this post with the problems and fixes if people post them here and in other threads. Here's things I've found with my E6600 so far..

The issue is that the P5W DH normally overclocks the 975X NB by changing its strapping from 1066 to 800. This gives better benchmarks at stock speeds, but limits the FSB speed. This feature is controlled by the "Hyper Path 3" BIOS switch; disabling this forces the 1066 strap and allows much higher FSB speeds without overvolting the NB.

FSB Wall at around 360-370 fsb - Enable SPD timings option in Chipset section of bios.

Extremely slow POST - Disable everything to do with fans in "Hardware Monitor". [Credit - OBR]

POST lock up during Detecting IDE Devices - Restart and plug in some USB storage OR change SATA harddrive to other header. [Credit - OPB]

VCore only option Auto - EITHER Flash using AFUDOS and the tags "afudos /i****.rom /p /b /n /c" (without quotes) , then clear cmos as the manual describes [Credit - OPB] OR Disable Speedstep and Enhanced C1 Control in the Cpu Configuration section of the BIOS. [Credit - DjLeco]

Slow POST (SATA Only Users) - If you're running all SATA drives (Optical and HDD) .. and are getting slow boot times mark the IDE ports and "not installed" in the bios .. saves you the 30sec detection time for each drive. [Credit - Silver Bullet]

Random 256C cpu temperature bug - Not really a fix but usuallyonly happens when running CPU-Z.

USB devices don't power off after shutdown - A standard feature of ASUS motherboards.

Motherboard cold boots when you restart - Seems to be a standard feature in the motherboard although it doesn't seem to do it at stock.

NOW FIXED IN BIOS 1503

BIOS seems to hang when entering Monitoring section - No fix.

Keyboard connected via a USB Hub. When system is shut down pressing the keyboard starts the PC. - No fix as of yet, Disabled PS2 Keyboard Startup does nothing to stop this.

Network Disconnecting - Upgrade Marvell Yukon NIC to latest driver; http://www.marvell.com/drivers/drive...?dId=116&pId=3 [Credit - BulldogPO]

CPU Fan Error upon POST when cpu fan is not connected to onboard header - Set cpu fan to Ignore in Hardware Monitoring section of BIOS.

Remote Control will only shutdown board and does not power it up - Enable "Power on after Power loss" option in the ASUS DH Remote control panel in windows. Also make sure the USB receiver is connected to USB Ports 3 or 4.

Blue Screen Of Death when installing Win XP SP2 - Disable 1394 (Firewire) and Jmicron controller from within BIOS.

Antec NeoHE Power Supply Units - Buy something decent.

Probe 2 and SpeedFan start reporting the CPU temperature as 128C. This goes away after a while. In this state, Probe alternates between 128 and 256, and Speedfan stays at 128. - Try Everest Ultimate Edition or use Core Temp (see notes below).

Silent CPU Fan Profile won't work in BIOS when Vcore is above Auto - Try setting to Optimal Fan Profile, worked for me..

Notes:

-- Cpu temperature reported by PC Probe or Speedfan etc is from a sensor integrated into the motherboard itself. To get temperature readings from the on-die sensor, use "Core Temp" (freeware) or Everest Ultimate Edition.

-- The motherboard temperature reported in any motherboard monitoring application is the reading from a thermistor placed on the pcb, not the 975x Northbridge.
