ASUS P5W DH - Problems + Fixes Thread

[Geek77]

I dont know if you noticed but the RAM timings are in different order on P5W-DH.

That is why many people have to use "by SPD", the memory won't boot with incorrect timings.

I passed through this myself, finally noticed the timings order and switched RAS precharge & RAS to CAS delay, no more instability, all workin like a charm.

Check on your systems, it is possible that they are switched and if they are - try configuring them manually instead of using "by SPD".



Before figuring this out - I also had "by SPD", and it was UGLY - the motherboard set them to 5-6-6-18 or something...

Now I found new problem, my NEC AD-7170 DVD writter´s Burfn proof feature does not work anymore, I´m using Vista X64 and programs like Nero and ImgBurn says it works but everytime when buffer runs out there is visible empty track disc.
I do´nt know if it is motherboard/bios related or OS/driver related problem.
Read speeds and write speeds are ok.
Anyone with similar problem?

i actually use the 5-6-6-18 timings. my super pi 1m result is better than using memset to make my timings 5-4-4-12. better by almost a full second.

for some reason memset won't let me change my cas from 5 to anything else. no one here seems to be able to answer why that would be...

Yeah, we all know that already and if you truly have the spd issue it doesn't make a difference. It's the ram, I know because I had it with my A-DATA's then I could boot manual timings with Crucial Ballistix.

@Cujo:

CAS Latency can NEVER be adjusted on the fly, it can only be set in BIOS.

how many people really use the built in wifi on this board ? coz for those that do i think mines broke my nokia n95 used to pick it up nobother then 1 afternoon just died it still looks as tho it connects but i get no gateway reply on the phone not a clue about networking so ??? and it can be the fone as i reset it and updated the firmware on it also im using the recent m$ drivers for it all the settings are the same as it used to work i have a feeling its vista uac but it didnt harm it before so if some 1 could shed a light on my problem thanks

Hi guys,

I want to take a pair of hard drives that are currently in the EZYRAID (RAID0) my older P5W-DH, and put them in a newer P5W-DH.

Can I just plug them in and hope, or is this naive, suicidal and asking them to be wiped?

I tried this and lost everything that ws on the discs. What happened to me was when I moved the jumper from the default RAID 1 position to the RAID 0 position and went into BIOS to enable the RAID it wiped the drives clean upon switching RAID modes.

Maybe if you switch the RAID modes before you attach the SATA cables you might get lucky, I don't know. In any case I strongly suggest that you backup the contents of the RAID array if it is something important to you..

I disable changing #Cas in memset. Impossible to change it under Windows on DDR2.

DDR was the same, no? and probably DDR3 aswell..

These coretemp/TAM temps ? You should be able to get a little higher with a later batch e6600. I have lapped mine too -didnt make much difference to temps idle 48 - load 58 so it must have been fairly flat already - but the CPU can take these temps. . You are running with a 4:5 divider - check my previous post re 1:1 vs 4:5 ifor FSB 400 or below. I run orthos stable @3.6 with memory 1:1 with 4,4,4,12,4 with 400 FSB with Bios vcore 1.5v(mount varies CPU to CPU) other settings FSB=1.3,MCH=1.65,ICH=1.2. I would think your RAM should run DDR 800 4,4,4,12 or tighter no problem Disable everything in the BIOS you dont recognise or arent using , Give it a go!

...no, possible to change #Cas under windows with DDR, on 865/875 915 chipsets and A64.
Probably impossible with DDR3.

A64 yeh true, but I owned 865 and 875 and neither could change CAS on the fly. Both instant windows freeze, like DDR2.

I just added an extra hard drive using the Jmicron connector because all the other ones are used. But I can't format the drive to FAT and only NTFS is available. Is there a fix for this? Thanks!

Guys! I really need your help !!!!
I have P5W DH Deluxe and 2x1Gg Crucial DDR2-800 with 4-4-4-12 @ 2.2V
The problem is that I managed to boot only with 1 dimm inserted to the third slot. It does not matter what stick I use - only while inserted in the third slot, it works. I tried all different BIOS version from 1506 to 2004, tried to switch memory timings from manual 4-4-4-12 to SPD. Nothing helped. Sent mal to Crucial - they know nothing about this problem. Any jelp would be appreciated.
If somebody has the same modules (Part Number bl12864aa804.16fd ), please attach your exact configuration in BIOS.
Thanks

wow... so my system was dead for about two weeks, wasnt really in a hurry to fix it cause i had finals and i was using my laptop... after classes ended i tried to boot up my pc and it wouldnt run. I remember the last thing I did was flash my BIOS to 2004, when it wouldn't boot up i thought it was a corrupted bios since it wouldnt post up at all (no bios post/no beeps/no video/nothing but fan)

I went and requested a new BIOS from ASUS, came in 3 days later and replaced my old bios, tried again and it wouldnt post up (the new BIOS had 2004)... I was like wtf, so I took out everything out of my rig and tried to check each part to see which one was causing the problem. I tested out the ram from my brothers comp and it posted... so I was thinking it was the ram, I tried each stick I had (1gbx2) and neither worked... so what I was thinking my ram was dead

my last attempt was i booted my rig with my bros ram and flashed the bios back to 1901 (was 2004) then I rebooted changed my settings to my old stuff and put my ram back in... and guess what? it worked... bah all this time it was the BIOS not liking my ram specs below (D9GMH)...

so basically im just throwing this out there just incase someone is experiencing the same thing as me... I was about to buy a new motherboard (I will later on though :P) or new ram... and all in all it was just a ram picky bios...

oh and remember when you flash your bios to always clear your cmos :P

[roger_h99.nor]

Good findings UZ7.

Let's see what the 2004 changelog says:

Enhance memory compatibility

[UZ7]

Enhance memory compatibility my ass lol! oh well... wow it feels so weird going back to my pc after getting used to my laptop...

[miochza]

Anyone use their Wifi-AP solo as a Soft-AP? I can't get my laptop to get an IP address from it. It can connect, but tells me "limited or no connectivity" so no IP address. ICS is enabled on the Marvell-Yukon Ethernet adapter.

Whenever I shut down my PC from Windows, my board doesn't shut off immediately, the HDDs and fans turn off, but the power LED remains on for about 2 secs before going off.

This didn't bother me until I installed a 8800GTX. When the power LED fades out after the 2 secs, the 8800GTX's beeper makes a short beep before the whole system 'completely shuts down'. It's the kind of warning beep you get if you forget to plug in your PCIe connectors.

Is there anyway to resolve this?

These are what I have .........

Yup, ditto here. Its a memory+chipset combination problem

BTW you can step down the multiplier to run 3.2 Ghz (400x8) - runs very stable for me. Easy speed increase from the 3.0 Ghz u r running, plus you can force the memory to run at DDR2-800.

I can't get my FSB past 379 with SPD off or about 395 with SPD on. I've tried using memset in windows to change the timings, but that didn't work for me. Everything seems to be running perfectly at 379 FSB with 4-4-4-4 timings, 1.45V, and auto vMCH, but as soon as I up it to 380, I start getting Orthos rounding errors. My temps seem alright with TAT (idle from 20C-25C, max load from 40C-45C, depending on room temp). Increasing the voltage doesn't seem to help anything, though I haven't played with the MCH voltage much. I'm using BIOS 1901.

What is a safe voltage to have this chip always running at? I've seen people post voltages as high as 1.7V, which seems really high to me. Then again, I haven't read one post about someone actually frying this chip. Also, what MCH voltage should I be using? I can go up as high as 1.85V.

Nice temps - you living on a glacier? I run a lot higher on air. Most CPU on air seem to need about 1.5 or more (amount varies CPU to CPU) to reach 3.6. My oher seetings runnng @3.6GHz are FSB=1.3,MCH=1.65,ICH=1.2. I increase MCH (NB) to 1.65 to stabalise for anythig beween 380-420 as a rule. then 1.75v if going higher As per CPU seems to vary board to board some get higher with lower. I would loosen memory timings to 4,4,4,12 until you get the higher FSB sorted. Disable everything in the BIOS you dont recognise or arent using e.g virtulisastion etc.

[Burner27]

So what's the verdict on BIOS v2004? I am on 1707 still and I am of the mind of "if it ain't broke don't fix it" about moving to 2004.

[lawrywild]

Just stick with 1707 if it's all running good, I doubt you'll see any increase going to 2004, I didn't..
