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.

**Fr3ak** · 08-06-2006, 06:45 AM

"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..

**inzane.oc** · 08-06-2006, 07:56 AM

will a 7950GTX work on the mb?

**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.

Yes, mem divider is biggest problem of this MoBo, i have good CPU OC, but i need more frequency to memory ... i will buy another board ...

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

Now at E6300@400FSB, noted

Have to enable SPD else the PC can't POST
Set on AUTO - Hyperpath, DRAM Thottling, all voltage settings except vMCH at 1.55V
Had to use 4:3 ratio to get stability with my 2 x 1 GB Patriot DDR667 sticks which kind of sucks since I can't even tighten the timings with SPD mandatory for POSTing.

Disabling Hyperpath3 did not help o'cing higher on my set.

**Silver Bullet** · 08-06-2006, 08:42 AM

SLOW BOOT (SATA ONLY) - If you're running all SATA drives (Opt and SATA) .. 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.

**Jimbo** · 08-06-2006, 08:43 AM

So would this motherboard not be reccomended then?

I have one on order to go alongside my E6600 and Gskill 2gig NR.

The motherboard is fine .. this is just a place to get around the common problems that people have been having.

**Mr.X** · 08-06-2006, 09:08 AM

Nice thread, it will be useful when I get my E6600 for sure.

**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).

btw, this seems only to happen with Asus Probe, Speedfan CPU temp monitoring does not report any swings.

**AndrewZorn** · 08-06-2006, 09:52 AM

i still get hangs on 903 when going into hardware monitor...
and my usb devices dont stay on

**$oul** · 08-06-2006, 09:56 AM

Can all these problems be solved by new bios? like the mem divider etc
there isn't any hardware problem with the board i mean ?

**John600rr** · 08-06-2006, 09:56 AM

Same with me on on 903.

**AndrewZorn** · 08-06-2006, 10:01 AM

not always though. not sure what causes it.

i DO know that back when my CPU was running hot... maybe 50*C+ idle/bios... it took FOREVER. for some reason better cooling speeds it up. also waiting before going in there helps too. like, if its the first thing you do superspeedyfast then youll have to wait, but not if you do other stuff in the meantime

considering these two things it is probably just verifying temps and whatnot, which is why higher temperatures may take it longer?

**arrakys** · 08-06-2006, 10:14 AM

prob using a noiseblocker SX2 fan plugged on the motherboard.. bios reporting stupid speeds (12000 rpm oO) and making hangs all the time in monitoring section or when using pc probe 2.

no fix yet.

**xgman** · 08-06-2006, 10:45 AM

AI Booster shows wrong fsb with bios 901 & 903.

**DEVIL_DK** · 08-06-2006, 11:04 AM

what is the best and most stable bios for this board.
