ASUS P5W DH - Problems + Fixes Thread

[lawrywild]

In my opinion, it's better to install using the latest drivers rather than these older ones anyway.

You don't need a floppy, you can put the drivers onto a usb flash and use that.

I just tried another set of CM2X1024-6400C4 ($60 after rebate) to get as much extra memory as I can get, and the PC locks up when even one stick of it is in. Don't even get to adjust any BIOS settings. This is with OC to 2.87Ghz/PC-6400 Dual Channel. BIOS 2302 (BAD for 4GB?).

I tried the new stuff alone in the original orange slots, and the new stuff alone in the unused-until-now black slots, and it works fine.

I see the reports of higher vMCH required by some, and not required by others, so I'm wondering where to go next. This P5W only goes to 1.65V and that's where I had it.

Can hardware revisions in the RAM itself make for incompatibility? I got some DDR for my Compaq that wouldn't work so I swapped it out for similar-to-what-I-had-looking chips from another manufacturer. The parts numbers on these CM2X1024-6400C4 are different from the first set, but the heat spreaders make it hard to see anything.

Would more RAM voltage be required, or just be dangerous?

While I wait for advice, I've gone back to stock BIOS so I can see what happens with 4GB. Unless a miracle happens, I'll have to pop 2 sticks just to change the BIOS again.

Really annoying when just plugging something in doesn't work...

you know Iceman and Snake eyes and a few others. I just bought and tried some patriot 4-4-4-12 memory it is their 6400 extreme xblk stuff. I pulled out 2 sticks of my G.Skill 6400 and put in their me right beside my 2 remaining sticks of G.Skill. the timings were set where they always are. 3-3-3-5 and I hit the start button and it was a no go! I thought maybe the mem sticks just did not like each other so I pulled my 2 remaning sticks of G.Skill still a no go.
Turned the fsb down to 390, still a no go the same at 380 so I backed it down to 370 and set the timings at 4-4-4-12 and it booted but it was not stable til i backed it down to 358fsb. This is supposed to great memory as is so many other sticks. I am telling you guys that I have a room full of G.Skill here and any combination of 2 or 4 sticks will run right up to and 400 fsb 1:1 with a quad core at 3-3-3-5 and up to 435 fsb with a duo core at 3-3-3-5!!
It's the G.Skill 6400 HZ it comes with the black heat spreaders... Get some!!
oh and Snake eyes as long as you have a fan on your memory I would say to go ahead and turn it up to 2.3V. anyway. Should be fine. Remember
Memory Matters..................
I will tell you all this also. Of the 13 P5W DH deluxe boards I have built on. This is the weakest of them all. I don't know why it is but, it really is. The 2 best boards were my very first bought in June of 2006 it was a rev 1.02 and the one just before this one it was a rev 104g. All the rest were excellent but those 2 were the real deal. I sold them both in systems. What you gonna do... This board just don't have that punch the others did but, it is a damn fine board.
I believe many of you need a change of memory more than a bios update.
2301 is turning out to be a nice bios.

Okay thanks.
So i go to set my memory to 2,1v
Than what for timings can i use i running now on 4.4.4.11
But if i set the FSB to 400 it want not start anymore (most turn off pc)
I would to get a best timings for 400FSB but cant find it.
And i would to find a best timings on stock speed 2,4 ghz (Q6600)
As i said my memory are Kingston HyperX DDR2-800 PC6400
The timings says in Everest Ultimate, 5.5.5.16 @ 400, 4.4.4.11 @ 266
and 3.3.3.8 @ 200.

I got the PC to boot at stock with 4GB, then I got it to boot using the 30% OC profile, then I got it to boot with 410FSB but using the first memory divider for PC-4800 (I did read the other posts before asking and saw this might work, but I didn't know if I'd get anywhere on my own.)

So I've stopped screwing around since if I make the BIOS change back to 1:1 again and it fails to boot, I'll have to pull 2 sticks out just to reconfigure the BIOS then shove them back in again and go back to 3.12GB as reported by Windows. I'll see how it goes for now with 'slower' memory...

Your problem is the 6300's low multiplier. 410fsb is just never going to happen with 4x1GB...

Just not at 1:1...

[lawrywild]

Stable?

[mikepaul]

Stable?

Only ran Orthos 57 minutes last night. Had other stuff to do. Will get more time in ASAP...

Just not at 1:1...

Precise problem I ran into earlier on in this thread. Now I have to get another motherboard, because I need the 4GB, but at the same time, I refuse to give up my 410FSB OC!!! I refuse to run the memory at 300 or 310MHz because it's now a bottleneck for the processor. I'm thinking about getting the P5K Deluxe.

...I refuse to run the memory at 300 or 310MHz because it's now a bottleneck for the processor...

Have you actually tested this? I have done some testing (gametesting and 3Dmark) that clearly suggest that the opposite it's the case; FSB is not the bottleneck.

No, what I meant is that if you run the memory at 300MHz with the FSB of the CPU being 400MHz, you are clearly running it out of 1:1 ratio. Granted, there are plenty of times people buy memory that is too fast for the FSB of their processor to make any difference. For instance:

266MHz = use DDR 2 533
333MHz = use DDR 2 667

In this instance, I am actually using a 400, actually 410FSB. So the memory has to be at least PC6400, which is DDR 2 800. If I don't use memory that fast, the memory FSB is going to end up being a bottleneck for the CPU FSB. It's sorta undermines the entire point of my OC if I am going to bottleneck the CPU FSB by lowering the memory multiplier; doesn't make any sense for the CPU FSB to be outrageously fast if it's going to be sitting around waiting for the memory to feed it.

If it can be proven that DDR 2 300 (DDR 600) will NOT bottleneck a CPU running at 400+FSB, then I'll be all for it. I clearly and logically don't think that's the case.

My plan is to get an 8-core 3Ghz model when I can afford it, and just run stock. I'm willing to keep this motherboard as long as that plan works out. I might never notice the 4:3 divider holding me back, but my next MB will have to be out longer so I'm not stuck with the first-and-buggy revision again.

Although, has anyone determined what the FSB drop would have to be to get 4GB to go back to 1:1 on this revision, just in case it looks necessary?...

I hear you. One of the primary reasons for me choosing the P5W-DH was so that I could upgrade to a quad core or higher in the future, as well as from 2GB to 4GB of RAM. The stability is definitely there, but this problem with the memory is a dealbreaker. I need to have motherboard that can do it all.

Can some tell me why i cant run 4.4.4.11 on 3.3Ghz Q6600 G0 ?
if i set it to 4.4.4.11 it dont boot anymore (no bios)
The timings thats works well are 5.6.6.18
I dont understand why it does not run on 4.4.4.11 on 3.3Ghz.

Can some explane me why this not work and what timing i can best use for 3.3 Ghz ?

EDIT: i have already found it was the volt of the memory
But to high can i set the memory volt ?
I got Kingston HyperX DDR2-800 2 Gig 2x1Gig 2048mb CL4.

[Zeus]

Your timings are not directly related to your CPU end speed.
Running 1:1 mode howerever forces the memory to run higher as soon as you raise FSB frequency.

Your mem will require more voltage the higher you raise their speed or you need to give them some breath by loosen up the timings like you suggested yourself.

Running a FSB/memory divider can help you increase or decrease your memspeed, thing is, these divider don't work well on this board.

At least not on mine, that's why i got me a P5K-E now.

[Putyah]

Currently my rig is running 3.4 ghz @ 1.42v. I have tested it with orthos blend test for 21 hour. No errors founds.

Recently my computer just shuts down. The harddisk, fans start spinning but there is no screen. After a few of and on turning my pc boots up again. When my pc doesn't start up correctly is get one long beep en 2 short beeps. I've tried to find it in the manual what this means, but couldn't find it.

Here are my settings and specs:

e6600@ 3.4 ghz @ 1.42
2 gb G-Skill @ 734 @ 2.05 4-4-4-12
Antec Neo HE 550 Watt

I have set the FSB voltage @ 1.30
MCH voltage @ Auto
Chipset voltage @ Auto

I think it is de fsb voltage the problem but I'm not sure. Please help me out.

Ps:Sorry for my bad English

i would advise lawrys 2004 modded bios link on first page of this thread i have a go stepping e6850 and it works fine with it

Hi GLENBOY, I was wondering if you could provide me with your BIOS settings. I am running the same CPU as you, and I would like to see some settings that might help me. Right now to reach 3.6GHz I have the vcore at 1.45v, the memory set to SPD timings @ 2.15v hyper path 3 disabled, and FSB, MCH & ICH voltage set to max.

I'm currently running BIOS 2301, but what do you think I would gain by going to the modded GO BIOS?

[whizmsm]

i just ordered my p5w dh off ebay, and i opened it up and it appears to be missing the heatsinks off the 975x chipset and the heatpipe that appear in all the pictures. Any ideas where I can get replacement ones?

[ntvh]

use water block for it

hi there yes personally with myself i have a higher vcore and use 1.5125 volt and its 100% stable also on ram i am usinf 1/1 divider i have the old board as well with a max fsb volts 1.65, the e6850s run very well in this board

[whizmsm]

The Seller!!! LOL

so what did you do with the heatsinks? can i please have them?

[mikepaul]

I peeled the metal covers off the NB and SB heatsinks (80MM side fan points in their general direction), but would some sort of cooler make the MB perform better?

If so, what fits?...
