ASUS P5W DH - Problems + Fixes Thread

Got a p5wdh yesterday... FSB wall at 430, can spi 32m 430x9 with my 6600, but at 433x9 it restarts...

My 6600 was tested on a bad axe and could get 4120mhz 1m stable with 1.56v (watercooling). Now im stuck at 430 fsb.

I cannot run the memory 430 1:1 3-3-3 from Bios, it crashes. I Cant even run 3-4-4 from Bios, and i do it with my bad axe at 2.35v (vmod).

Flashed last oficial bios (130X) and i get nothing. I am at 1.65v mch and the board is a 1.65vmch max.

Changed the termal paste to AS Ceramique, and put a couple of fans around the mobo. No result.

Someone has any advice?

Damn... I LOVE my bad axe :(

Dit you check the SB-sink for flatness??? Had to lap that one and put a small fan on it to go from 430 > 440.

vmch = 1.6V, couldn't pass 440 stable, 1.65V didn't help... (MCX159cu on NB)

and I couldn't get CAS3 at this speed 1:1 either... (bios 1401)

E6400 aircooled cnps9500cu

Uhmm I didnt check SB-sink at all, but Ill do, thanks you.


Seem that we are at the same point hehe, but you a little better (440). The Cas3 thing sux :(

Thanks

I just swapped out my Bad Axe for a P5W-DH and am starting to regret it. I can't quite get the P5W stable at 425 and even this requires 1.85 vMCH, and I HAVE to run mem at SPD or it will not boot no matter. I had the Bad Axe stone cold stable 24/7 at 437 and could run benches at 452, just had to get there with setFSB in windows. Thinking about doing the vMCH mod on the Bad Axe and putting it back in. Being able to set the 1333 strap in bios is a very nice thing too.

It might be something else like your RAM - FWIW both my P5W can do 425 at 1.65vMCH. And that is 48hr+ Orthos stable.

The SPD thing seems to be RAM related - I can boot at manual timings with the ram in my sig.

People tend to forget the SB is connected to the cpu too...
I noticed the problem when switching from 1.05V to 1.20V on the SB, things got worse... So I took off the sink and it's not remotely flat... Took me a lot of grinding and lapping to make the center touch the chip...

Might be that the ICH7 is the real reason why P5B Dx outperforms most x975-boards at the fsb-side... (pure MHz, not necessarily raw performance)

cas3 wouldn't bother me if I was capable of running 4:5... doesn't work either at this speed, but I really didn't have time to look into it, maybe I do something wrong... spd settings don't help me much with 5400UL...

BadAxe is hard to get (read expensive) in Belgium :-(

Thanks for all the info! Ill try at 1.05v, and Ill check SB. BTW I didnt removed the cover of heatsinks, Hope it helps.
P5wdh its a good mobo, with a lot of extras and 1.7vcore + 2.4vdimm. Bad axe only goes 1.60vcore (1.57 real) and 2.2vdimm.

But its more powerfull when you are talkin about pure FSB. It has less vdroop and clocks nice. I get mine from taiwan, but well... now its dead.

I hope I can finnaly get my 6600 ES at 4100mhz :(

Thanks,

I have mentioned earlier that i couldn't get 415+ with my mobo.I rmaed it and now i have a new one 68xxxx that came with 401 bios stick but it was flashed with 1305(maybe by retailer:confused: ).It has vmch 1.85 option at bios but there is no option for ecc!I flashed to 1405 but nothing again.wtf?
I tried to boot 415fsb that the previous one refuses but no luck again.I tried 420+ and it's ok..:clap: .
Another issue is with vmch.I used a multimeter and at "auto" reads 1.3v!At 1.85 option it reads 1.6v!Anyone knows smth about this?
Conclusion:1)Conroe platform has many many bugs..i'm pretty sure of this and you need time to find the way to solve them,2)where is the ecc option?,3)why does the mobo gives so low mch voltages?
I'd appreciate any answer of you guys..

Well the voltages error is because of my two multimeters' low battery.I checked it at mt friend's one and it's fine.:rolleyes:
The problem is with ecc option.There is no way to be in BIOS.I can see it at boot screen only if i put the battery off,but after reboot it disappears!It's a pity to rma because there is no ecc option.I'm unlucky..my ram is ecc fatties!:(

I have an Issue with the q-fan on this board. I have connected two fans to the powerfan connectors and set them to silent operation in BIOS. The problem is they only stay quiet for a while.. as soon as I for example run Prime95 to load the system the fans start to run at full speed as they should, but they won't spin down when the temperatures decreases. I have to shut down the system for a while and then start again and the fans will run silent again. Anyone know a solution to this problem? I have the stock Intel cooler on the CPU.

Say ignore in the BIOS and let Speedfan automatically control it?

Do you think the following storage tower with SATA port multiplier (model ST5X1PM) with work with the esata port of the P5W DH Deluxe?

Storage tower


The Jmicron site says the JMB363 "Supports Port Multiplier with Command-based Switching on SATA II port" - see the spec at this link:


JMicron JMB363 spec

Seems like a pretty cost effective external storage solution if it will work.

Hmm...any try this out and notice any changes?? Wish they had a change log in the zip file... :stick:

My problem.

Bios doesnt recognize the timings of my RAM which are 4-4-4-12. It thinks it's 5-6-6-18, and I cant change them because it wont post when I set "Configure DRAM timings by speed" to Disabled.

you have increased vdimm?

it's nothing to do with vdimm, it's the board setting too low tRFC

I have the same problem with Corsair memory.

My memory is G.Skill DDR2 800 4-4-4-12, not the HZ kind though, just the regular.

Glad to know at least its not only me with the problem. Someone should add it to the list! :)

Oh and yes I tried increasing the vdimm, however I shouldnt have to, because its running at 375Mhz with the slower 5-6-6-18 timings. So its actually being underclocked.

Are you sure its the board setting the tRFC too low? And do you know of a possible fix?

For the record, BIOS 1405 is really buggy. It reports an "overclocking/overvolting failure" everytime I reboot, even though I had been using that stable clock frequency and voltage for days... I'm too lazy to roll back.

1405 or 1407 ?
1407 is the newest beta one...why are you using 1405?

I had problems using a bluetooth mouse with the 1405 bios, pointer jumped around and connection problems. 1407 seems ok.

1407 does not overclock as well as 1405 for me

FSB Wall at around 360-370 fsb - Enable SPD timings option in Chipset section of bios.

is Asus capable of resolving this problem by newer BIOS?

i readed somewhere that its a memory issue that occur only with some kind of dimms. Is that true?

The problem is tRFC, the board sets too low tRFC (for either the ram to handle, OR the board, we don't know really). SO yes, if ASUS add tRFC into memory timings options, then it's fixable..
