ASUS P5W DH - Problems + Fixes Thread

[Burner27]

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

Thanks for the feedback.

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.

Sorry, I meant to say Coretemp... TAT shows a few degrees higher than that. I'll try using 1.65 MCH and 1.5 vcore with 4-4-4-12. Is it safe to run your CPU at 1.5V all of the time? Just asking because it's quite a bit higher than the specs from intel which show a max of 1.325V. I don't care if I shorten the life, as long as it lasts a couple of years.

Also, can someone clarify this for me, because I keep getting different answers. What program do people usually report their temps from? I'm at part load, and Speedfan currently says 22C, Coretemp says 25C/28C, and TAT says 27C/32C. Which temp am I supposed to report?

[cujo]

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.

thanks for the reply. i've actually just bought a p5k deluxe cause i'm sick of this mobo. with raid 0 on easy raid, 80% of the time at boot it doesn't see the drive so i've got to restart it. combine that with the inconsistent frustrating overclocking i'm fed up.

i know you're thinking why not use the ich7 ports for raid but i want to install a 5th sata device and i REALLY don't want to use the jmicron crap.

Coretemp is what u use to report internal core temperatures.The data is collected from a Digital Thermal Sensor which is located in each individual processing core, near the hottest part. Running 24/7 upto 1.55v on air if you have good low temps should be fine - you are overclocking after all!.

Thanks for the info, I won't worry about setting my voltage to 1.5V 24/7. Is yours set to 1.5V in BIOS, or is that after vdroop?

The reason I asked about the temps is that I wasn't sure if I was supposed to report the Tcase or Tjunction, and Coretemp gives Tjunction instead of Tcase. It's hard to get a good idea of whether my temps are good or not when everyone I'm trying to compare them to is using different sensor programs and reporting different kinds of temps. Would you say that 25/27 are good idle Tjunction temps? Thanks again.

I run 1.5v set in BIOS vcore. For comparision I run 48c idle - 58 load using coretemp. So compared with me you have very good temps!.

[cbell]

Great, thanks for the reply. I'll try pushing it to a stable 3.6GHz again tonight and I'll let you know what my temps are then. I'm sure I'll notice very little difference in speed between 3.42 and 3.6, but at 3.6 I can say that I'm getting a 50% overclock, which is a nice round number

[cbell]

Sweet... I'm Orthos stable at 3.6Ghz with 1.4875V and 1.55 vMCH. I set my ram back to 4-4-4-4 2.1V, and it's working great. My full load temp fluctuates between 55 and 60C in CoreTemp... not sure what the idle temp is since I'm still running Orthos right now. Anyway, just wanted to say it's working and thanks for the help!

BTW, is it safe to up the MCH voltage if I don't have any kind of extra cooling on my NB? All I did was replace the thermal compound with AS5 and took off that weird cover on the heatsink.

[Eastcoasthandle]

If you have a revision 1.04 board does it matter which bios you update to? If someone has a 1402 bios should they attempt to update?
As you already know this is the MB that has the increased voltage for mch, etc.

Nice o/c - you can probably get more out of the CPU if it will do 3.6 on 1.485v as long as the memory will run 1:1. MCH increase of .1v isnt that much but helps stablity- I stuck a small 40mm fan on it to be sure. Check the MB temps. MBM 5 version 5.3.7.2 reports temps and volts okay on this board with a little calibration. I stuck a post in this thread previously as did others.

[cbell]

Thanks for the program, I'll give it a try as soon as I get home. Is this program capable of reporting the NB temps? I thought that the temp sensor on this board was located in the SB. Also, the board comes with a small NB cooler, but it warns you not to use it if you have active cooling on your CPU or else it will mess up the air flow. Is anyone using that fan? I think I'll go ahead and try it out and see if it affects my CPU temps.

I dont have this MB ( or ne intel for that matter or DDR2) but Im trying to help a friend OC his system ( over the phone) . I will list what I have tryed so far ne imput small or large is a great help .

So far this is what I have had him do .

updated bios to 2004
Set ram Divider @ 533
Under Chip set disable By spd
Vcore set to 1.4

I am Aiming for 3.2 with this setup .

He has a p5w dh / e6420 / d9 2x1gig ram /stock cooling.

So far we have hit 385x8 . It passed Super Pi 1m and 10 min of orthos. But was random reseting in CSS .

Like I said I dont know much about these new toys , Should I get him to up the MCH and NB voltage ?
Thx

MCH is the NB setting. As with any CPU overclock BIOS settings for memory,Vcore,NB,SB and other settings will decided on what you can achieve Read the first page on his thread and this setup guide may be of use http://forumz.tomshardware.com/hardw...ict197995.html.

Link does not work for me.

Has anyone managed to put a Thermalright HR-05 heatsink on the NB of this motherboard?

I bought some and have installed one on the SB, but the NB uses the clip type installation, and the clip provided will not work (although the installation instructions illustrate a different 'universal' clip that would work if it was supplied).

I know Thermalright officially state that it's not compatible with this board (due to the heatpipe arrangement), but I would be prepared to forego the mosfet cooling if I can get this on the NB.

[nifty]

Hi aoe, I had the same problem, so what I did - you're not gonna believe it - but I used AS5 and screwed the HR-05 to the top of the nb cooler, and - you're not gonna believe it - it worked unreal. Before - nb heatsink very hot to touch @ 1.65mch. Now - nb heatsink only just warm. I've now lapped the HR-05 and will lap the top of the fins on the nb cooler before glueing the HR-05 back on top with thermal adhesive. I understand if some of you think this is whacked.

[~aoe~]

That is an ingenious solution

I ended up reseating the original HS + heatpipe and putting a small fan on the top of the NB. Seems ok, but would really like to get that HR-05 on. The annoying thing is that the installation instructions show an illustration of a retaining clip that would work (2 hooks on each end oriented perpendicular to each other) but this is not the retaining clip that was supplied.

I've recently changed my case (from CoolerMaster Stacker STC-T01 to Silverstone TJ-07), and the ventilation on this new case isn't as good. I've been working on improving both the air circulation and cooling (additional 120mm front intake fan, HR-05 on SB, replaced Scythe infinity with Thermalright Ultra120 Exteme, Scythe Kamakaze 120mm on HS, trying various case fans - SilenX/Scythe/Thermaltake). I had to drop my OC to 3.2GHz as I was getting some instability (and some video corruption during POST).

System appears more stable now with the latest modifications, and I will try and put it back to 3.4GHz tomorrow. I did try vMCH at 1.65, but with no noticeable difference in stability.

Current voltages are:
vCore: 1.3750v
vMCH: 1.55v
vFSB: 1.40v
vICH: 1.20v
vDIMM: 2.2v

Temps (if I can rely on the readings):
tCase (cpu): 27C idle / 49C load [SpeedFan readings without offsets]
tJunction (core): 30C idle / 53 load [TAT readings]

Ambient is 22C atm. As summer is coming, I can expect ambient to rise by as much as 10C (then the fun will start).

I realise that the temp difference between tCase and tJunction is not within specifications (should be ~15C difference so I've been told), but as I have no single temp reading that I can definitely prove is accurate, I am unable to establish the offsets I need to apply. BIOS temp is the same as tCase at idle.

Load program was TAT.

If anyone has any comments or recommendations on voltages or whatever, please let me know.

You probably want more vcore to get higher than your current settung. About 1.45 -1.5 for 390-400 FSB. You only need to try increase MCH if you cant post or get stable. I would recheck you heatsink mounting - Ifrom what I have read you should get much lower load temps than that with the ultra extreme - I was going to get one but I wont bother if you have it mounted okay! and thats the best it can do!!!!.

[revenant]

anyone running a Q6600 on their P5W DH Delux @ 400*7 ? 2800mhz and memory 1:1 for 800mhz?

I guess what I am asking is if the downward mutlies work well on the P5W DH with a Q6600?

edit: also, how is running the memory on the p5w dh in odd ratios (not 1:1).. when I had my p5w dh that didn't work too well for me.. I'm skimming now, but thought I would ask also..

I was also expecting better performance from this HS. You won't believe the number of times I've reseated it though. Even though I can remove the motherboard tray, with the HS installed it won't slide back in (hs too tall).

There seems to be no difference in cooling performace with the attached fan at high and low speeds which seems a little odd. The base is always cool to the touch also (even under load).

I guess I may have to consider lapping.

[Luis_GT]

All I can say for the 2004 bios

DON'T USE IT !!

Its ruined any overclockabilty this board had

use to run my E6600 at 3.8Ghz.
Now it won't accept 3.4GHz
Resfuses to boot.

Off to E-bay heaven for this board
Bring on the P35 Deluxe

I don't know about that. When I flashed to 2004 I could finally get my CPU all the way to 4GHz... although after I turned my PC off, the Bios craped out on me.

[GFORCE100]

I wonder what CPU cooling this must have been? The 2004 BIOS allows a higher FSB on the QX6700 from what I could tell. I think I could get it up to 371MHz before crapping out. Insane heat at 4GHz, enough fry some bacon and eggs on without being late for work

How did you volt mod your 7950GX2 and how are you cooling it?
