ASUS P5W DH - Problems + Fixes Thread

[NghtShd]

I can't get the built-in wifi to work. Windows doesn't seem to find it at all, and installing the newest drivers off asus.com does nothing. Any ideas? Do I have to enable something in the bios?

All 8 USB ports should be enabled. That's the default. Did you disabled some or all USB for some reason?

Does anyone know how i can get dvd movies audio or music to go through the coax digital output for the sound card to my Harmon Kardon reciever for my system?

are you using onboard audi or a sound card... need more info

Hi,

I tried to clean install Build 5744 – RC2 but failed with the following error:

"CD/DVD drive device driver not found. Please insert CD, DVD, USB drive, etc that contains the driver files. It is safe to take the Vista DVD out of the drive for this step."

It’s pretty strange to have this as my DVD-RW is not one of the latest models and should be included via cdrom.inf. Although I tried to manually locate the inf file, it failed yet again. I could not have a chance to test this with a DVD-Rom.

I’ve just wanted to see whether anyone had similar issues with LG DVD RW or P5W DH Deluxe or even with any other brand.

My configuration is:

Asus P5W DH Deluxe Mobo (BIOS : 1407)
DVD RW - LG GSA-4160B
Intel Core2 Duo E6600 CPU
G.Skill 2x1GB. DDR2 800MHz.
Samsung 160 GB SATA2 NCQ 160JJ
Asus EAX1900XTX

Thanks in advance!

sorry. I will explain again

With a Enermax it works, not problems. But now with my new OCZ it doesn't boot, or any fan moving, nothing. Yes, everything is connected, 24V, 12V, the connector for my graphics card, etc.

I have a tester for power supplies and I did a bridge betweend green color and black color and the power supply is working.

I don't understand why is not working.

Is any difference between the connectors CPU1 and CPU2 I mean, different voltage ???

Sounds like your board may be shorted some where remove the mounting screws and re seat your board make sure you dont leave any extra mounting screws in and every thing lines up properly. I had this problem with my older board when I first set it up. Good luck.

I'm using the onboard sorry,

Same type of RAM (8500C5) No problem running it at 1:2.
Using bios 1305.

Dang you r lucky cant get mine to do that even with 1305. Crucial says The Corsair 8500 is not supported with this board and has difficulty running with a 975x chipset@ 1066 fsb. Wont hurt to try. But in the mean time if your having problems run the ram at less then 1000 mhz and it should work and you can tighten up the timing and should run fine until asus can fix bios to support this ram to its fullest extent.

Weird experience:

I was working on a word document and my computer rebooted. It was at 3.0Ghz with 1.32Vcore. It had been stable (not prime 95 6 hour tested) but stable in that it survived probably 45 minutes of prime 95 the day I got the OC, and it had not restarted randomly for a whole month. Out of nowhere it restarts. I lower the OC in bios to 2.4GHz while maintaing the 1.32vcore just so I could get my word document done and then deal with the OC later. However I open up word, and after 15 minutes it crashes again. So ok, its clearly not the OC, because it should be totally stable at 2.4Ghz with 1.32vcore. I put it stock and it hasnt done a random restart since.

Another quirk I have with this board:

I recently install the remote, and ever since then when I turn on my powersuppy (WITHOUT pushing the on button on my cas), after about 3 seconds the computer starts up. The fans spin, hard drive spins, internal speaker beeps as it normally would at bios, but no signal goes to the monitor. I then just hold the power button to get it off, and then push it again and it will all boot up fine with no errors. This is happening ever since I install the remote.

Very odd.


And a question. What vcore roughly should a 3GHz 6400 OC be set at. I found that 1.32Vcore (1.375 in bios) to be stable until this experience (although I doubt the CPU's voltage had anything to do with the random restart)

Thanks for your answer. I am using a new power supply Enermax 620W and it is working perfectly. I don't understand why my OCZ doesn't work I did the same thing with my new Enermax. Anyway, the point is now everything is working and this motherboard is great.

Dummit the 6600 is soooooooooooo fast

thanks guys for your comments.

note: at work, we are using Enermax with a UPS 24/7 andd we never have problems. Maybe is just luck, I don't know. I tried all my best with OCZ power supply. My another idea was Corsair but anyway, I have a Enermax and it works...........at the moment with my UPS at home.......... fingers crossed

I had 2 disabled, not sure why. I enabled all 8 now, but nothing happened. Windows still can't find the WIFI card.

That's odd. It's my understanding that the WiFi adapter is just an internal USB dongle (on a nonstandard plug). That would also explain why it can't be directly disabled in the BIOS.

Swapped my 1.65v for a 1.85v revision in an attempt to solve my missing RAM problems - sadly, no go.

Strangely, there seems more subtle hardware differences between the older 1.65v and the newer 1.85 boards besides their vMCH, especially with S3 support.

The S3 resume behaviour is different when it comes to the JMicron ATAPI support (1.85v is much better supported by Aug 06 drivers else I get missing ATAPI device issue while 1.65 boards are already OK with Jul 06 versions) and the onboard generic USB hub (1.65v tends to S3 resume at USB1 speeds, 1.85v no problems - yippee!). The differences were noted on both the original 1001 BIOS which the 1.85v revision came with and the 1407 BIOS that I am using now ie. seems BIOS independent. Edit - went to 1305, missing ATAPI device issue solved.

now i've read almost every page in this thread, and what are you suppose to be the best bios for overclocking i have 1101 in fo now but it's not satisfie me that much, so you who have a great overklocking tell me wich one that is the best, i have the rig in sign and MB is that version that have 1.65v to chipset in bios...

I'm pretty satisfied with 1101 , maybe have a look on 1403 and try some lower multi

[chefnr1]

ok have to try out som different bios and se wich is the best...

[irfs]

I can confirm this is TRUE i spent hours figuring it out then i realised. You can also try re-installing Wifi drivers. Also if you still see unknown item in device manager then you need to install pc probeII.

See, the problem is that windows doesn't seem to find the damn thing at all. There is no such thing as a wifi adapter in the device manager! Very weird. I don't understand how it can be so complicated to use a wireless network card

[jagt]

Uhh... I went into the bios, set the all USB ports enabled again and saved. Now windows all of a sudden found the wifi. Weirdness!

Here's a few things i have found with my early dh.Bios 1403 has been the best overclocker for me,seems fairly stable apart from occasional loss of video signal at boot/post.
My board will not boot with memory frequency > 499mhz,or fsb much above 400,so i boot with < 399fsb and < 500mhz memory frequency and then memset trd to 7 and my memory will go to 547mhz 4-4-4-4,but not 1mhz more at any volts/timings/devider.Memory stops dead at 547mhz.This board does not seem to like cas 5 at all,with either of the rams in my sig.
My northbridge (fsb limit) goes to 463 fsb (1m) @ 1.9v on normal water,more volts don't help,did about 414 on stock cooler 1.65v,and about 435 on water and 1.65v.
All deviders seem to work fairly well,except the 3/5 (cpu/ram),which seems unreliable,although i haven't looked too hard for the reason yet.
Lower cpu multi's seem to stress the cpu more,at least on the x6800.
Thats about all i've learnt for now,except for 1 last thing,the fact that asus has the 2nd and 3rd primary ram timings totally reversed to all ram software,is totally confusing,annoying,and unnecessary.

I'm not sure that lower CPU multipliers really stress the 6800 more.
I think what happens is the CPU tries to complete its "power up" routines at the default multiplier (11), before the BIOS even initializes. That's why the X6800 won't post at lower multipliers and very high FSB unless you increase the vcore. The Nemesis already found this out. The vcore increase you need is equal to the vcore needed for posting at the exact same speed you would have if you were using an 11x multi (example: 400 FSBx9=3600 mhz, but would require the CPU to be able to low level POST at 400x11).

That's what I've found out; maybe I'm wrong.

You should be able to test this by using CrystalCPUID to change the multiplier in windows, from your normal stable overclock (let's say you are using 360x10=3600 or 328x11, and then a clockgen or setfsb or whatever to increase the FSB. (goal=400x9?) CPU should still work at the exact same voltage if the mhz remains the same. But it simply won't POST at 400x9 as it tries to post at 400x11.

Multiplier unlocking is done by the BIOS giving a command to the CPU to lower the multiplier, if I recall correctly, not by "writing" a new multiplier into the CPU flash memory or something like that. Otherwise the CPU would keep the lower multplier as default if you switched motherboards, which it does not. (correct me if I'm wrong).

How did I come to this conclusion?

Rather simple, actually.
my X6800 cpu posts and runs fine (dual prime stable) at 360x10=3600, 1.5125v. But put CPU at 370x10=3700, and the CPU won't even POST (which is unheard of for anyone doing a 100 mhz clock higher). If I increase vcore to 1.55v, it posts all the time. 1.575v for stability in windows/games.

That only makes sense if the CPU were actually trying to POST at 4070 mhz (370x11) at 1.5125v, before BIOS takes over and lowers the multiplier.

Yep,that all seems to make perfect sense to me,but i was saying that i think i noticed higher cpu temps (more stress) running on the lower multi's,than on the higher ones,at the same voltage,probably due to increased fsb,although i thought greater fsb would heat the northy and not the cpu.Nice tip about the pre post multi/vcore thing though,cheers.

very interrresting !

have to try bios with unlocked multi to compare .

[kevsta112003]

Does anyone know if their is a way to make it so it doesnt say "Intel CPU uCode error" everytime I boot when the CPU is oc'd?

It's happened on everyone I've had. And ive been updating since 0701 I think it was.
