ASUS P5W DH - Problems + Fixes Thread

[aledsav1]

Thanks yeah have raised volts to all areas 1.5cpu and maxed Vmch...though e6750 has 8multiplier so 3.646ghz is my max stable with fsb@456 i am sure there is headroom as i boot vista fsb466 though orthos fails pretty quickly

[Polynikes]

Damn, you're getting your FSB pretty high. You can't get much more out of this mobo than that. If you want faster FSB speeds you'd be better off with a different chipset.

[aledsav1]

yeah pretty much knew i was doing alright with those sort of fsb's shame as my e6750 is crying to be pushed higher.

[roger_h99.nor]

Raising the fsb yields better results than raising the MP, in terms of performance.

My advice is to lower the MP to minimum (6) in order to find the board max stable fsb. Once established max fsb it is time to raise the MP again. (Loosen the ram timings to take this variable out of th equation.)

@Polynikes,
based on your (seemingly) very good airflow I would bet it is safe to give 1.85V a try. Put a finger on the NB - if instant burn, it is time to back off

One of the very best fsb I've seen on this board.

Oh, that sounds nice. Too bad they don't have temp sensors in NB's. It would make life a lot easier, huh? :P

My Vcore is bumped to 1.5 in my bios, just bump the vcore up and keep and eye on temps. I have no mods on this board at all, it is bone stock and that goes for cooling too just my cpu is water cooled. So even though I have vcore set to 1.5 now it reads 1.45-1.47 under Everest.. bump that Vcore and leave the MCH @ 1.65 no more no less and set the term voltage to 1.4 no higer no less

I'll give that a try. Do I need to change the southbridge voltage?

[gwolfman]

Here's a few screenshots of my setup. This is the best I've gotten out of it. So far, it's passed two instances of Orthos (RAM and CPU tests) for about 15 minutes, a 32M superpi, two full runs of 3DMark06 (just the gaming benches, not the other stuff) and I played Counter-Strike: Source with 11 bots for about an hour with all the settings maxed. It's pretty stable, at least for what I do with it. I'll probably do more rigorous testing in the future. Here's the screens:

Bios2

Hope this helps. Keep in mind, your machine may boot slower, so wait an extra 30 seconds or so before shutting it off to try again. See below.

Is there any way to "fix" the stall when booting when you've overclocked a lot? My machine takes an extra 15 to 20 seconds to get to the POST beep. I'm glad I waited, otherwise I would've never known this thing was actually capable of booting at these speeds.

Thanks, I'll compare and let you know.

[Polynikes]

Good luck.

Page 2: Disable ratio support and run it @ 9x, (I have a Q6600 so this is my max x9) I have found even trying to run 8x to get my memory to 800mhz even while running the 400FSB CPU @ 3.2 I still had to pump in more MCH rediculous as that may sound and the system was still not stable. Not only that benchmarks did not show significant improvments running it @ 400fsb 800mhz 3.2 nor 395fsb 795mhz 3.5ghz. So I settled for my 378fsb and the system is stable and I am happy....

Page 3: I disable peg link, it is garbage and will OC the video card and make your system unstable in my limited knowledge

[Polynikes]

Well I tried for 400, 395 and 385 with your suggestions but no go. Upping the ratio at 375 to 10x made orthos fail within seconds, and I like the balance between speed and voltage I have going right now, so I think I'm just gonna leave it as it is right now.

[nrs250]

I too have found that 333FSB is a stable OC. I can boot into windows at FSB 350 and www is OK but I ran DVDShrink and I crashed out and rebooted.

Here is my CPU-Z

My Settings:

BIOS 2103 (2004 gave me a CPU uCode error)

AI Overclocking set to: MANUAL

CPU Frequency : 333MhZ
DRAMM Frequency :800Mhz (1:1 according to CPUZ)

Memory Voltage : 2.1v
CPU Vcore Voltage : 1.4 (1.37 in CPU-Z)
FSB Termination V : 1.4
MCH Chipset V : 1.65
ICH Chipset V : 1.2

COOLING: Nautilus 500 WC
Temps: 46C idle and 60C at 100% load

The above is stable but I will run orthos tonight.
I think that my Rev. C0 board is at its limit.

What do you think. Is it worth another board to push higher?
I was a bit disappointed since I was pushing 400FSB on my E6400 but then again this is a QUAD.

Anyone think that a P5B would yield a 4 GHz. clock?

[MarcusTaz]

What do you think. Is it worth another board to push higher?

ALL depends bro, I am quite happy with 3.4ghz and I use my system for everything including gaming for hours. I love the performance comming off an AMD X2-4800 939... I mean this board is feature packed but if just pure Ocing is what you are after and pushing the very limits of your CPU then they say the P35 or better yet I read the X38 will be out in October...

Me, I love this board, maybe not the best OCer but I love it...

[gwolfman]

I can't seem to get past 378-380 FSB no matter what I try. Also, I've seen posts with people running this speed or even faster with WAY less vCore. If anyone has any ideas on how I can get past this wall I'd be greatly appreciative. Btw, I turn down the RAM speed one notch when I try to go higher (in this case, 750MHz).

Dump the AI booster and use something else like Everest.. I noticed this created instability for me....

[Polynikes]

I think a lot of it is luck. In the link I referenced (http://forums.vr-zone.com/showthread.php?t=88306) the guy got a Q6600 to 400FSB on less than 1.4 vcore. That's nuts.

I think it's really just luck of the draw. If you get good parts, you can get great OCs, if not... Oh well.

I should've gotten an E6600. :P

Hi all,

I'm currently at 400fsb on my p5wdh, but I have an old rev with a max mch of 1.65. What's the best way to get a recent-rev board?
I've got this board pretty well figured out now, and it doesn't seem like the newer boards have much advantage as yet.

I'm running the northbridge watercooled... seems like this is where my wall is right now.

Thanks!

[nrs250]

nerve007 can you post your BIOS settings including BIOS rev, CPU voltages, FSB term. voltage, memory etc.

Thanks

[~aoe~]

I'm running the northbridge watercooled... seems like this is where my wall is right now.

Which block are you using on the NB? Any problems installing?

I'm in the process of building a water-cooled system around this motherboard and was considering including the NB in the loop. Can't decide on a block though

Thanks in advance

I woudnt seek out a new rev board. Just do the vMCH pencil mod, it's very easy and gained me about 35 more FSB (390 to 425)

http://www.vr-zone.com/?i=3876

I'm running 1.81V on the northbridge right now and am stable up to 425 or so. Can boot as high as 440. This is on stock cooling with good air flow.

[Polynikes]

No kidding. What are the potential drawbacks to this mod, besides the obvious warranty voiding? I mean, as long as you're not putting too many volts through the NB, can this cause any other problems?

[John600rr]

I can only speak from my personal experience so take that into consideration.

I have been running 1.8V through the northbridge for about 8 months now with no problems whatsoever. And 10 seconds with a q-tip you would never be able to tell anything was modded on the board.

Technically, I suppose the pencil mod does void your warranty, but in all actuality I have found it would be hard to actually cause serious damage using it. Mainly because it would be hard to lower the resistance enough with a pencil to add more than 1.9V. No matter how much lead I added I couldn't get mine above 1.85. Which is right where the later revs allowed you to go through the BIOS.

What do you mean by "created instability"? I'll give Everest a try.

Anyone see any settings I should change/try in BIOS?

[aledsav1]

Just an update on my efforts
e6750@3.718=fsb@465 max multiplier8 can't say stable yet though have run orthos for 10mins only, which is a massive improvement as its been freezing system until now. moved my memory back to spd rather than manual which helped.
vcore 1.55 on water = 40c load
vdim 2.15 60m fan cooling
mch 1.85 removed silly casing 40m fan
fsb 1.2
ich 1.4
shall see what happens nxt. goto say thanks for thread/posts been of great use.
