ASUS P5W DH - Problems + Fixes Thread

[5OH]

I'M ONLY GETTING 3.2GHZ on air at the moment. no matter what i do it wont clock any higher and be prime stable. i think there could be certain settings needed or conditions i have yet to find. strange as i could get 3.6 easily with the e6600 installed instead of the quad....

I have a similar situation, but can only get 3GHz (9x333).

So you have a Q6660 and can mange to get 3.2GHz (356MHz x 9 I suspect?) with the P5W DH? Is so, please post your BIOS setting.

Oh what BIOS are you using?

[5OH]

I see this presently on the Commando 1404 BIOS too but for that mobo, it is a misreporting of speed on POST. The set multiplier actually works as can be seen using CPU-Z in Windows.

Anyway, do give 9 x 356FSB a try if you are still going for 3.2GHz. I am not sure if the P5W can do 400FSB with quads. Haven't had the chance to try it out yet with my SLACR, still testing it on my Commando.

Are you 100% sure the BIOS is reposting it incorrectly and it's not the software (CPUZ) that's reporting it incorrectly?

I tried many clock settings and none will work above 333MHz x 9 for the Q6600 CPU. Interesting enough I had an E6400 at 3.2 (8x400MHz). So it has to be an Q6660 + P5W DH issue

I don't know why but with the quads, the P5W DH won't allow you a high FSB.

If I tough the northbridge it's very hot so that could be the reason (having to handle more I/O requests due to more cores).

It will do 333MHz though giving 1333MHz effective, even without bumping up the voltage.

the B3 q6600 top out at about 350fsb if you are lucky on the p5w motherboard, not sure on the new G0 stepping ones, i had a qx6700 and thatr would only go to around 320fsb on the p5w

I guess it's just a limit of the board when it comes to quad cores, which I kinda expected

Time to upgrade this system to a P35 mobo I guess.

[roger_h99.nor]

Could ppl with problems with this combination please investigate the vdroop? (use Speedfan, I find this fairly accurate).

Problems reaching high fsb only during load, or also in idle?

Maybe the vcore circutry on this board is too weak for 4 cores.

Planning a quad on this board, but not until autumn.

Regards.

101% sure on Commando, not even 0.01% sure on the P5W. You've got to do your own investigations for now.

btw, you can't compare dual and quad core FSB o'cing even on the same mobo. Prob. going to test out the SLACR on the DFI P35 next so can't feedback the max. FSB on my P5W for a while yet.

I´m getting 3.2GHz Orthos stable and 3.36GHz SuperPi 8M Stable.

[dddan]

I have a few questions I hope someone can answer.

1. Is there a general overall problem with the P5W DH and the Q6600 CPU (G0)? Because I have a Q6600 which I know can overclock to 3.2GHz on air on a P35 mobo, but I can only get 3GHz (333x9) with it on the P5W using water cooling. I'm using the 2206 BIOS.
2. On P35 boards using the Q6600 multiplier 6, 7, 8 & 9 are available, but on this board even when I select multiplier 6-9, it always defaults to 9. I take it the multiplier can't be changed when using the P5W DH with the Q6600?
3. I would like to try an older BIOS, but can't seem to because it tells me I CAN'T LOAD AN OLDER BIOS. I tried using a floppy and AFUDOS, with same result.

Help would be appreciated.

I can help with (3). Get yourself afudos 2.11

this seems to allow you to go back to earlier BIOS revisions - later versions won't.

BTW my replacement BIOS chip should be arriving tomorrow. I will never trust Asus Update ever again! Been without my main rig since Friday night and I feel like I lost my right arm!

Not bad, 8 x 400 or 9 x 356?

Respectfully disagree. I run my system everyday @ 378 FSB and I can run it @ 395 if I wanted but I have to put to much Vcore into it. Your talking maybe an average possibly? I have B3 currently and a G0 stepping on the way and then I will know for sure if I can run 3.6ghz stable I am oonly looking for 400fsb and PC 6400 on the nose. If I can get those numbers I will be very happy indeed!

thats quite impressive.
What volts are you using?

? Are you even running a quad core? Don't expect to get the same fsb on a quad as a dual.

Are you using a Quad core CPU? If so, I for one would love to know your BIOS setting

I bet you are:
1) Not running a quad core
Or/And
2) Own a very recent version of the P5W DH using a 975X chipset revision that's newer than C1.

[purecain]

replacing my Q6600 b3 with a go..... it isnt even prime stable @3.2 anymore.... i'm sure the board isnt helping but i cant help but think the G0 will give me better results. i used to get 3.6ghz 24/7 on my e6600....

[MarcusTaz]

Yes running a Q6600...

As far as revision of my mobo, I have just purchased this from newegg this very month so I am sure I got the latest rev.

Oh and if the G0 stepping is not any better I will gladly keep this B3 and just settle for the 3.4GHz... But that 400FSB 3.6GHZ and 800MHz even #s would be nice. I am just anal like that...

[lawrywild]

Is that my 2004 you're running (G0/45nm edition)?

Or official

No Larry you were not nice to me when I asked you a question.


I will give it a try after I get the G0 stepping...

[nickfd]

Thanks Ragdd.

I tried using both floppy and cdrom with P5WDH.ROM file in the root of each, but have no luck. I get no output on the screen whatsoever and if I press CAPS or NUM lock keys, no lights switch on on the keyboard. I do have a core2 processor installed - am I going to have to buy a cheap Celeron to be able to reflash this?

I had this same problem once before. Only one of the options worked for me, and I can't recall which it was. Floppy, CDR, or usbstick. But for sure it worked!

Run CPU-Z or Sandra and tell us what revision of 975X chipset you got. C2?

[MarcusTaz]

Rev. C0

What are the differences, I guess I have the older Rev...

After trying to find info on a C2 stepping 975x I cannot. I only see a C2 stepping on a 965

It would be useful to know - if you ever remember, be sure to post about it.

I got no output whatsoever (although my proc. is a Core2 and I have rev. 1.02G board) so I wasn't sure if it would be able to boot an old bios with this processor anyway. It did check both cdroms when I switched the PC on, although when I tried it with P5WDH.ROM on the root of a cdrom it totally ignored it. It also ignored the same file when I loaded it on a floppy drive.

Oh well, new bios chip arriving tomorrow so hopefully will be sorted out with that.

UK posters (who cannot get Asus to supply a new chip) might find this place useful:

------------------------

Incidentally, I found this link on the web for AMIbios - it suggests using a different filename instead of P5WDH.ROM when trying to recover from floppy, CD etc. I'll post it here as I think you guys might find it useful.

http://www.ami.com/support/doc/AMIBI...epaper_v10.pdf

I'll try it with my old (ruined) BIOS and let you know if it works.

[nickfd]

One guy that got my same batch of q6700 on a phasechange cooling setup got 360x10 with 1.4 vcore. Attached is pic.

That's a good sign if it requires that little voltage to hit such a high speed. g0 rocks!!
