ASUS P5W DH - Problems + Fixes Thread

[NghtShd]

I have a big problem. The second core on my 6600 stops working after I leave my pc on for a while. When I reboot, it goes back to normal. It'll then work fine for a few hours or maybe several days straight, but eventually it happens again. I'll run something multithreaded and the first core will be maxed out and the second core will be virtually unused. I tried a fresh install with xp pro and home and same problem with both. I ran Othos the last time it happened and got the following error message: Affinity Mask: Process: 0x1 Sys: 0x3. Anyone have any ideas on what's going on?

Sounds like a software problem to me. I'd think if one core really became dead/comatose it would cause nasty things to happen.

[Mxtra]

That's what I was thinking too, so I was suprised that a fresh install didn't change things. I use a program called svcd2dvd for encoding and it's multithreaded. The last time I found only one core was being used I closed it and ran Orthos. Same thing happened for Orthos, only one core got stressed. This sux cuz there's virtually no help online for such a problem. Not enough people have dual core pc's.

Sounds like a software problem to me. I'd think if one core really became dead/comatose it would cause nasty things to happen.

LOL, keep posting in this thread please and see if you beat this one.

Well, I tried 1305, and for me at least, 1402 is better. More stable.
With 1305, when I boot at 390 fsb, I cannot bench and it shuts down after about 30 seconds with 1.7 vcore.

Same vcore and fsb of 390 with 1402 and I can bench and stays running.
So it is 1402 for me all the way.

Ok... thanks again for your insights... you are going to save me a lot of time!

On the subject of BIOS... What's the verdict on the latest 1502 bios people?

[SpaceCadet0]

Or... POST stop after memory check.
For me, the problem I discovered was actually the PWR_FAN1, or the use of both PWR_FAN2 and PWR_FAN1 to power my case fan and the optional fan. So now I just plug the case fan into PWR_FAN2, forgo of the optional fan. ASUS manual should have highlighted "Installing the optional fan with an active CPU cooler ]<i.e. a fan> will interfere with the airflow and destabilize the system." THey're quite right, I only wish they made it be known better.

Other than that, my P5W DH runs like a dream.

[ccl2006]

In your experince is 1305 better than 1407?

The "optional fan" that they talk about here is the extra fan that came with the mobo and it mounts on top of the heatsink that is between the cpu cooler and the back of your case (covering mosfets).

I have a fan connected to both PWR_FAN1 and 2 with out any problems
infact, I have 4 fans connected to mobo besides the cpu fan(actually 5 if you count the one on the splitter)

[bichi]

Using PWR_FAN1, PWR_FAN2 and CHA_FAN1 with no boot/post delays or issues.
- (not using PWM aware HSF or ASUS MOSFET fan)
- BIOS fan controls all set to DISABLE (1502)
- Zalman CNPS-7000 AlCu with 478 to 775 bracket

i just installed my wc and my temp drop 40c during full load!

with same room temp (25c) and same oc setting (400x8) orthos showed intel stock fan full load @ 80c while my new wc setup only 41c!

i'm so happy..

i installed ASUS mosfet fan and connect it to pWR_fan2 without any problem..

Hello!

I would like to thank everyone who posted in this thread for providing great information. I've been reading this thread all week, and finally finished reading it all. I am new to overclocking, and have managed to get a nice and stable 3.2GHz on my E6600 with air cooling (400*8 - FSB:RAM = 1:1).

Here's a link to my Orthos test:

My only consern now is my Geil ram. It is rated 4-4-4-12 @ 800MHz, but the board won't POST if I set the STD timings to manual . This means I'm stuck with 5-6-6-18 timings. From what I've read here, this is because the board is setting too low tRFC.

Is there nothing I can do to fix this besides waiting for a new bios? It seems like a lot of people are having the same problem...

Have you disabled hyperpath in bios?

[virtualrain]

Hey guys, I'm going to be overclocking my buddy's rig tomorrow with this Mobo... We are replacing the stock HSF with a XP120 and Scythe S-FLEX fan. My question is, how do you connect a normal 3-pin fan to the CPU 4-pin Mobo PWM header correctly? Do you just connect the fan to the three left pins and leave the "CPU FAN PWM" pin unconnected?

Please reference the pins as mentioned in the manual (See attached pic).

Also do you recommend having the fan speed controlled via BIOS and if so, what settings? If not, we can use Speefan... is that recommended or not?

Thanks!

[bichi]

Assuming its a standard three-pin fan connector with tab relief....
- line-up tab dentent on fan 3-pin plug with tab on motherboard connector
- personal preference, I don't use BIOS fan controls, all disabled in BIOS
- old Zalman CNPS-7000 AlCu with 478 to 775 bracket is quiet at full volts/speed for me
- other fans are large, low-speed, low noise types, with ample CFM

[irenic]

now i am running orthos blend @ 4hrs+ with 413x8, vcore auto, vmch 1.65, vfsb up 1 notch, vdimm 1.9 @ 5-5-5-15.

[Pluppo]

Have you disabled hyperpath in bios?

Yes it's disabled.

No matter what memory timings I try at 400MHz FSB, the board won't POST. I I managed to set the memory to 4-4-4-12 @ 800MHz when the FSB was 266, but what's the point of that? This is very annoying, because I could have bought a cheaper ram with high latency instead of this one.

Here are my settings using a template from an eariler post:

@ Pluppo,you could try setting ICH V to auto,FSB V to auto,performance mode to auto and bump the memory voltage to 2.2/2.25v.Also,why not bump the vcore a little,run the 9 multi and go for some clockspeed ?

[Pluppo]

I tried setting ICH, FSB and perfomance mode to auto, 2,3v on the memory, and I still can't boot with manual SDP timings. As for the multi, I get too high temperatures in the cpu in full load when the vcore is higher, and I want to run this overclock 24/7.

Here is someone else having exactly the same problem as me:

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.

And

I have the same problem with Corsair memory.

And here's what lawrywild says about the issue:

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

[Thickbrit]

i still think you'd be better off on the 9x,even if you dont increase vcore,but thats just me,and each to his own eh?.If it is the trfc,just for testing you can boot as high as you can with manual timings,then memset and clockgen your way higher in windows,just to prove the theory.Also if you cant run more than 3.2ghz or 1.375v without overheating,then something is wrong.

[ROCKSOLID]

What happen when you set a lower FSB like 366 or 333Mhz? Can You set manual timings? You could determinate the manual/auto breakpoint FSB.

[phogger]

I have never been able to boot with the FSB > 400Mhz.

My best stable 24/7 OC follows Lawrywild's efforts, but I found that I had to increase vCore to 1.6125v:

I have the E6600 and Corsair RAM PC8500.

My best manual memory timings 4-4-4-12 were achieved at 370 FSB (3333MHz)

Ambient temps in the acreage office have been cool, so the TAT and Coretemp beta processor temps have been acceptable, even though I run on air.

[nicepun]

I made a couple of changes to your settings, they are in BOLD. See if you can it now, also do you know what IC hips your memory has? One last thing, vcore might be too low but if you say it's stable for you then I guess it is what it is.

Yes it's disabled.

Just to let you guys know that I've gotten another Week27 and it cannot do 450x8 @ 1.5125 like my other Week27, however it can do 400x9 @ 1.5125 no problem and it is able to do 450x8 but @ 1.600vcore. Which makes me think that each CPU has a FSB wall. I'm still testing away.


Here are my settings that might help some one. Below you'll see the 450x8 and 400x9 settings (The only diffirent value is the one in (), everything else remains the same). Rock Solid Stabled.

CPUZ question>>

I am using 1.36 CPUZ and have ram at SPD for the moment.
Any idea as to why Trc is reported as "1" and then sometimes "24" which should be correct?
TIA

[BulldogPO]

Why you do&#180;nt update CPU-Z to 1.37?

[liquoredonlife]

Does anyone know of any programs that can get SMART data off the Intel ICH7R RAID0? Normally I use SpeedFan but it comes up empty with my 2x320g 7200.10 RAID.
