Asus P6T Deluxe Discussion Thread

[003]

Guys I am having a very annoying problem. 222 X 19 is pretty stable, but as soon as I go to 210 x 20, the system BSODs as soon as there is any kind of load on the CPU. PLL 1.9v, QPI/DRAM 1.35v, CPU vcore 1.475v, DRAM 1.6v (on 6x multi), IOH 1.3v.

This is getting extremely frustrating. In fact, 222 x 19 is way more stable even than 200 x 20 with Turbo enabled AND disabled. And why the **** is turbo only available on Auto multi? On other boards you can always use it, and even force it to be always enabled. But I am getting side tracked... not the point of this post.

How the heck can I make 20x multi stable?? This is killing me here.

[gOJDO]

I have mine 20x200MHz stable with turbo off, HT on, vCore = 1.375v, vUncore = 1.46v, vDIMM = 1.74v, vIOH = 1.46v, vCPU PLL =1.96v

As for the turbo working with lower multi, I was wondering the same. But I really don't need the Turbo options since it was causing instability to the system when turned on. I've never tried 19x222MHz, but I'll try tonight. Anyway, higher BCLK yields higher performance at same core speed (and higher power consumption as well). If you can make it 4.2GHz stable then why would you need the 20x multi?

I do hope Asus makes the 21x multi available in the next bios. It really is a pain in the ass the Asus doesn't support that kind of option.

Btw, does raising DRAM and QPI/DRAM helps stabilizing Uclk? Suppose so, but my P6T doesn't want to run stable at 3600 QPI with 6x 1GB 2000MHz Kingston modules running at 1600MHz

Sorry for not reading all 10 pages, but what issues have you guys had with the board? i have read a lot of complaints but non were specific.

i got this board on sale at microcenter for $285 but don't know if i am going to keep it. So any advice?

I got mine at microcenter too for the same price, currently have my 920 at 200x20, linpack and prime stable, and that's with 12Gb of corsair @ 1600 9-8-8-22.

I even had to exchange the first P6T I got because it was missing the northbridge screws, but it ran at the same settings, also linpack and prime stable.

Don't know why anyone has issues with this board, been rock solid for me.

thanks m8,

finally one answer i was looking for.

I really want to hear all these complaints i've read about yet no actually proof just that its "a bad board"

[lowdog]

P6T-D working fine for me - i7920 @ 195 x 20 for 3.9GHz with 12gb ram at 780MHz 9.9.9.24 and 4870x2 + 4870 1 GB TriXfire.

Raid 0 on 2 x 150gb Raptors and overclock profiles work fine. No double boot up with current overclock on either cold or warm boot. Bios 1102.

vcore - 1.31250v bios LLC enabled = 1.2960 idle in windows and 1.312 load in windows.

IOH and CPU Clock Skews set to 100

Dram - 1.62v

QPI/DRAM (QPI/VTT) - 1.32500v

CPUPLL - 1.84v

ICH - 1.2v

IOH - 1.14v

all other volts set to stock not auto.


First boot up I left all volts on auto, loaded windows at stock clocks then checked in TurboV utility to see what volts the bios was setting for stock on auto.


Bumped to 20 x 195 and set ram speeds manually but left timings on auto and all volts on auto to see what the bios was setting for that overclock. Auto volts were fairly high - vcore was 1.4, QPI was 1.375 can't remember the rest hehe. Anyway I managed to get them all down to what I'm using now.

Ran LinX with maximum amount of ram to test with 15 passes, took nearly 4 hours and was solid. Ran Prime95 Large FFT (large FFT has proved to be a better test of stabillity than small FFT or blend, blend and small may pass for ages but large FFT will show instability before the other tests will) and it was solid for 8 hours, repeated same tests over and over and all seemed fine. Seemed stable......played some games and they kept stopping with the message "such and such game.exe" has stopped working and needs to be closed" windows message.

Solution to the game instability problem - had to bump ICH Core volts up one notch from 1.10 to 1.20v and IOH volts up 2 notches from 1.10 to 1.14v and now games run fine.

So even though LinX and Prime ran fine over and over games had problems and other volts had to be tweaked to get more stability for those specific tasks. Play away guys but this board has been great so far once you get the right combo of volts for you cpu and config.

Is anyone having issues with Bios 1102? I updated mine and when I try to run Convert X to DVD or Nero Vision to re-encode movies, I get BSODs, specifically Vista_Driver_Fault in the minidump file. I am using Vista x64 Ultimate. I flashed my board back to Bios 1003 and have not had any BSODs...yet. Can anyone confirm best BIOS to use?

Thx

[Astratuner]

was the error with your graphic card related?

Seems that P6T Deluxe +1102 bios doesn't seem to like EVGA cards :s

Some say it's due to memory voltage is on auto...


What BSOD error are you getting? Could be be more specific...

Is the issue a Vista Driver, Convert X to DVD, or a hardware issue? I ran MemTest and it came up with no errors.

[Astratuner]

Maybe a long shot but I think that Vista 64bit might be the one to point the finger at... ( long shot...I think)

Try to update some drivers, vga, chipset, audio, windows update


You never know

[Pisklink]

I'm running 212 x 19 at this moment and wanted to add HT as well. However CPU-z reports only 2 cores are in use if I turn on HT in bios. Anyone a clue what the reason could be? I thought it was just turn on the HT setting in bios.

Additionally (but in a different session) I wanted to try turn on some energy saving option. But which one should I use so my comp. won't run 100% when idle all night? Or should it be disabled when OC'ing at 4Ghz?

All of those have been done already. The only thing I did after that was revert back to the 1003 bios and, so far, I have BSODed while running those apps.

[Burner27]

I am convinced it was the BIOS that was doing it. So far (knock on wood) I have been using BIOS 1003 and not one BSOD during encoding with Convert X to DVD. Maybe the 1102 BIOS does some how affect the voltage to the ram?

[duldog]

wow nice blck settings you guys... any secrets you want to share??? my Blck maxes out at 207x20 with turbo on, ht on. 1.45vcpu 1.64ram. my issue is windows freezing at 210blck. more voltage???

It gets even weirder than stated above. Even at default bios settings with only RAID enabled CPU-z still reports only two cores. How is this possible?



I will try the following things:
- Set default bios settings by using the reset button on mobo;
- Look how many cores CPU-z and task manager report with HT enabled and disabled at bios defaults;

In case CPU-z and task manager reports 2 cores with HT enabled and 4 cores with HT disabled, I could safely conclude that HT doesn't work correct? Is it possible to flash my bios again with the same bios version or should I revert to a lower version if possible?

[Pisklink]

SOLUTION
I found the solution and felt I needed to share this with you.

I knew that HT worked in the beginning after I just installed Windows. I started figuring out what I could possible have changed that could cause this problem.

I recalled that I changed the amount of processors (cores) Windows should use to start up. I set this amount to 4 processors in the "BOOT advanced settings" section of msconfig. Apparently this causes Windows to only recognize a total of 4 cores / threads regardless of what is set in the bios.

Yes, and it's a misnomer that setting that will speed up your boot. It's NOT telling the system to use more processors, it is LIMITING the system to a certain number of processors for the purpose of troubleshooting.

I assume you unchecked the "number of processors" check box then?

I've had the same problem with my HDD. I was getting lockups even while displaying a web page. The most obvious culprit seemed to be the HDD. I benchmarked it with HD Tune and the read performance was abysmal (around 20MB/s). I plugged my drive from SATA port 4 or 5 (can't remember) to SATA port 1 and it solved the problem immediately so I might have a bad SATA port. Try that you never know, you could have the same buggy port.

Though I am very pleased with the overall performance of this board, there are an other 2 very annoying bugs: OC Profile doesn't work on this board (No RAID here) and the battery doesn't work either. In fact the battery slot is very badly inserted in the M/B. Since I very rarely shut down the PSU, it's not a huge problem, but still.

I think I have the same issue. 2 of my drives are plugged into ports 3 and 4 and when i try to access files, the drive(s) sounds like it is spinning up, clicks to ready state, then i can access my files. I have to find out why they are spinning down.

[buddatech]

nvm

[Pisklink]

@ Burner

Well, I checked the box myself in the first place. I had done this previously with my E8600 just in case it would speed up the booting process. However that CPU doens't have HT obviously so it wasn't a problem. I did the same thing now with the i7 but after unchecking the box again HT did work because it seems that this setting is only limiting the amount of cores / threads used by the OS.

I had the same issues and started to play with energy settings in Windows. And additionally tried to install newer chipset drivers. Installed Intel Matrix Storage Driver. And Installed Marvell drivers as well but they seemed useless and removed them accordingly. Nontheless at this moment I don't have the issue anymore of HDD's spinning up or locking. I just don't know exactly what did the trick.

@ All

I have contacted Asus about the dual boot problem and accessing OC profile. After trying some suggestions the helpdesk employee forwarded my problems to the R&D department in Taiwan. I sincerly hope they will do something about it in there next bios update.

I had to try the following things. Reset bios to defaults by using the jumper on mobo. After that RAID setting will jump back at IDE. When it's on IDE I can access EZ flash en OC profile. However when RAID is enabled I can't access EZ flash en OC profile. Seems to me that this is obviously a bios bug. The moment I could access EZ flash I decided to revert to bios 1003 and try but still the same issues. Therefore returned to bios 1102 and suddenly dual boot is gone. Really weird and Asus definitely has to work on this. I suggest everyone to contact Asus support about this so they will recognize this as a common bug.

[Burner27]

Well I am using the 'balanced' power setting and I set the HDDs spin down to never. I also went into the bios and I set the Suspend Mode to S3 instead of the default of AUTO. I do not know what AUTO sets the suspend mode to but in all my previous machines, that setting was set to S3 only.

The HDDs do not spin down now.

I found the difference between S1 and S3 which explains why my HDDs would shut down:

S1 is the simplest energy-saving state, often used in older systems whose drivers or hardware won't behave well with more sophisticated levels of power management. A system at the S1 power level simply shuts down the hard drive(s) and monitor, but leaves everything else running normally. Different vendors call S1 by different names, but sleep or standby are perhaps the most common.


S3 is a deeper power-savings mode that shuts down almost everything except for the barest trickle of power needed to keep the contents of RAM from fading away and to listen for a wake-up action. In a way, you can think of S3 as a "suspend to RAM" state. In fact, many vendors do refer to S3 as "suspend" mode, but others (alas) may call it standby, sleep, instant on, on now, and the like.


I guess the AUTO setting does a little of both? Now, I can understand why powering down your HDDs when not in use is a good thing but the constant power down/powering up when needed seems like you'd shorten the lifespan of your HDDs right?

What are the chipset cooling blocks you have on that p6t dlx ?

sorry i havent kept this post updated.

i am running custom CnC blocks which i had my friend custom build me.

You can buy them though vendors tho @ jab-tech and Sidewinders.

As for the problems you guys are talking about.

i havent had any problems minus not having a turbo option.


The board did not like a gainestown cpu i had into it (was messing with this guy),


see i lost 2 OC options in bios:


so i went though a 920, which the board loved:


Currently im on a 965 and im waiting for a 975 to throw on.

I am using Raid 0: i have 5 raptors connected.

And i am on dual HD4870X2. I havent had any issues you guys are reporting, however im starting to think maybe your boards are somewhere overheating? (mosfets possibly?)

[pispuso]

First of all, hi to everyone, this thread really helped me a lot with my new rig, still, i have some questions.

I just bought an Asus P6T Deluxe of course, a i7 920 and 3x2Gb G.Skill 1600Mhz 9-9-9-24.
I was messing around with the bios, trying to get some nice numbers, was pretty hard with the stock bios, so i downloaded and updated to the last bios version. Anyway, the best i got was 189x20 = 3780Mhz. Of course i wanted to hit 200 BCLK, but its impossible to go past 189... i raise it to 190 and i dont even get a POST. It doesnt mind if i try with a lower multi, 190x19, 190x18 or even 190x17 wont even POST. But of course, at 189 i have no problems at all.
Turbo Mode its disabled, im testing so the vCPU is 1.35v, the CPU PLL is 1.96 and QPI/DRAM 1.35.
Just to try, i enabled Turbo Mode later, it boots without problem, and i can run Super Pi 32M and 3dMark06 at 21x189 = 3969Mhz...

Whats the problem here? :S Is there any way to go past this 189 BCLK wall im hitting? >.<

Thanks in advance

EDIT: Might be the CPU who's hitting this wall and not the p6t? Damm if i got a bad batch

[buddatech]

need help getting stable... just switched from a evga x58 to this p6t deluxe and can not get same stable settings, have to use MORE voltage and still not stable




was 5hrs and some change p95 stable too....
