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.

Slow posting - Disable every fan Q-Controls in "Hardware Monitor", it is working for me, after disabing of it i have speed boot up.

**SpaceCadet0** · 10-21-2006, 06:42 AM

Or... POST stop after memory check.
For me, the problem I discovered was actually the PWR_FAN1, or the use of both PWR_FAN2 and PWR_FAN1 to power my case fan and the optional fan. So now I just plug the case fan into PWR_FAN2, forgo of the optional fan. ASUS manual should have highlighted "Installing the optional fan with an active CPU cooler ]<i.e. a fan> will interfere with the airflow and destabilize the system." THey're quite right, I only wish they made it be known better.

Other than that, my P5W DH runs like a dream.

The "optional fan" that they talk about here is the extra fan that came with the mobo and it mounts on top of the heatsink that is between the cpu cooler and the back of your case (covering mosfets).

I have a fan connected to both PWR_FAN1 and 2 with out any problems
infact, I have 4 fans connected to mobo besides the cpu fan(actually 5 if you count the one on the splitter)

I have now bios 2105 , but it seems that everytime i boot my computer the bios resets , and i have to start my pc up by entering bios setup and choose Exite and DISCARD changes . I've tried everything , even changing the battery.
I wanted to flash up an older bios , but i couldn't do it with Asus Update or Asus EZ Flash , and Asus DOS just jammes .
PLEASE HELP ME

**Bloke** · 07-29-2007, 09:17 AM

So, has anyone tried BETA BIOS 2206, yet?

Anyone wants to share what's changed?

Thanks!

I tried them, they are buggy (i.e. vcore which wants to stay on Auto each time you get into BIOS and the HD Audio which disables each time you get into BIOS) but other than that I don't see anything better. I'll stick to 2103 until something good comes out.

**w2richwood** · 07-29-2007, 04:38 PM

think i killed my put the back plate on for my tt bt and now all it dose is move the fun a lil then off have to restart the power to get it to do it again . tryed clearing cmos deffrent cpu took the baack back ofthink it has a short but cant see when any ideas guess its new mo time

2103 DOES support Q6600 G0!

SL9UM B3 CPUID String = 06F7h
SLACR G0 CPUID String = 06FBh

Awesome

Hi there, i have a problem with VOLT DROP on the cpu/vcore,

i have a QX6700 @ 1.35v bios, during load in windows this drops to

1.30/1 and its very anoying in trying to get stable overclocks,

i could rase the vcore manuly but i want to use speedstep etc,

so this leaves with with no options to ajust the vcore,

is there anyway i can fix this? ive tried the pencil mod with no avail.

You must be not using a HB pencil or pencil modding the wrong resistor as the mod works if done correctly.

Thanks man , problems solved now , but i can't get anymore with my E6600 above the 3 Ghz , normaly i could do 3.7 easy , how would that comme ??

"BIOS seems to hang when entering Monitoring section"
Thats no bug, it takes some time no matter what bios version

"Motherboard cold boots when you restart"
Thats some kind of OC protection. Annoying, but no bug.

Furthermore I cant boot with manually set ram timings above 400FSB. Works fine for 400FSB and below.
There are some more things that seem to act up when running above 400Mhz FSB (random reboots).
Disabling Hyperpath, EIST, Speedstep, C1 helped some guys getting higher OCs.
"Random 256C cpu temperature bug"
Happens to me only when I open CPU-Z.

It is a bug, you'll find that sometimes with bios's before 0801 it'll take about 4 mins but with 0801 and above it takes no more than 10 seconds.

Never said the cold boots were a bug...

That's what this "FSB Wall at around 360-370 fsb - Enable SPD timings option in Chipset section of bios." one is for.

I'll look into the cpu-z thing..

**k0nsl** · 08-06-2006, 09:16 AM

Hmm. I never experianced this with any bios. 4-5 seconds is the absolute max I have seen with any bios.

0801 gets there instantly (for me).

mine wont boot when i plug my psu
the onboard green LED (SB_PWR) is blinking
is my mainboard faulty?

**DEVIL_DK** · 08-06-2006, 08:19 AM

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

help me right now i run 380 fsb the higest i have ben able to boot up at.
before max where 360

**Pandamonia** · 08-06-2006, 08:27 AM

the mem dividers just dont work properly at all.

this mobo is rubbish, im waiting for OCZ tony to test it next week maybe he will figure it out

**Haltech** · 08-06-2006, 08:29 AM

Larry, the BIOS doesnt seem to hang for me prior to 903... however, its about an 8-10 second delay before it pops up.

The memory dividers and no manual control over memory timings is what is making me upset.
