Asus P6T Deluxe Discussion Thread

[McBacker]

martinakerman,

Why are u using CAS 8-7-7 and not 7-7-7? Your sticks are CAS 7 rated, aren't?

Again no full support for Xeon in bios 0504 It`s a shame

I think the multi-dropping is triggered when the tcase (shown on Asus boards as CPUTIN under hardware monitor) exceeds 67.9. I watched realtemp and hardware monitor for quite sometime to conclude that. I think CPU is throttling because it thinks its in a hostile environment.

So, no matter what your volts are or what your ambient is, a consistent tcase greater than equal to 68C will drop the multi. Anybody can confirm that? Or not. How do we know sensors are working consistently across motherboards?

Asus needs to disable th damn throttling.... Its so annoying to test something and use something else. I test 4.1 in Linx when I think it is 4.3Ghz.... And it will randomly crash on me someday.

Asus bios for now is a really mess
We urgently need a beta bios as Rampage II Extreme:

I just finished a new version of my tool to check for Turbo throttling and started a new thread here:
http://www.xtremesystems.org/forums/...66#post3808966

Hopefully some P6T users can head there and post some results of their testing. I plan to start a list there of motherboards that have the Turbo throttling issue. If there is enough negative press then maybe Asus will fix this issue.

Probably not but at least a list might help keep users from buying a board that has a serious issue that the manufacturer is not willing to fix.

I could really use some of your results ben805 to show the world what this problem is all about.

There is a new bios 0504 in the ftp server for the v2 board.

And it doesn't have the fix for S3 resume (like it claims) and it doesn't have the fix for multi dropping from 21x to 20x. Such a shame!

Sorry for the late reply, have been busy doing a few photo gigs but whenever I have a chance I'll revisit this problem again soon. As long as Asus ignore this multiplier dropping issue I can not recommend this system board to anyone except to those who own a weak chip that are not Prime/LinX stable above 4.2Ghz. My finding so far is this damn board is handicapping my D0 chip to 4.2~4.3Ghz (@4.4~4.5 OC).

Did you get the evga board? How is the NB fan and heat on NB? I have heard its bad from many folks, but some folks say its alright. What was the case for you?

I still can't decide to get the EVGA vanilla or the Classified. Yea from what i heard the vanilla version has loud NB fan and they tend to run much hotter than the Asus which I have never seen rise above 45C under heavy load.

I was in the same predicament , between the classified and the RIIE and i went with the RIIE and a extra gtx295 to boot ..cause I'm used to the bios more and the north bridge on the classified runs to hot for my liking. i should receive it tomorrow.

Can you find out if there is a linkage between the tcase and multi dropping? tcase is reported by hardware monitor (winbond chip reports it as cputin). I think its not the TDP which decides the throttle but the tcase (which has a relation to TDP but is determined by the ability of the cooler to get rid of the heat from CPU's vicinity quickly), which when passes tcasemax, cpu throttles.

vanilla and classified are $100 apart.... Its not a choice for me. Although EVGA support may be good, who wants to takes the hassle of returning a fried board. And with those temps running in 90C's, any serious use is going to decrease the life of the board. I am surprised that EVGA overlooked this. I have a feeling that evga boards are designed with WC in mind.

And S3 sleep doesn't work on vanilla evga or asus boards, so there is nothing to choose there. If Asus can fix this multi issue, I am happy with sticking with Asus because this board is solid otherwise.

martinakerman,

Why are u using CAS 8-7-7 and not 7-7-7? Your sticks are CAS 7 rated, aren't?

Yes, they are.
But at 7-7-7 @ 1.66v it makes the system restart , i should increase a bit more the voltage, and i don´t want to do that.
Other thing is i am running 12Gb the all 6 slots copulated, and may be this has something to do with it.

Ok... got it... i also own a CAS 7 rated KIT (Ocz Platinum) and it only runs at CAS 7 if i put 1.7v on them... anything lower than this will fail on Linx in the first 10 seconds... i asked about this at OCZ Forum and they told me it's ok to use 1.7v.

The OCZ Platinum XTC 7-7-7 1.65v ?

I have 2x3GB of XTC in my Dlx V2. Tho I havent tested LinX, I can run prime just fine @ 1600+ Mhz 7-7-7 with 1.6v
Running 01 and spi @ 1750 7-7-7 with 1.66v
I have not yet maxed them out since my "old" C0 tops out at 4570Mhz in 01 and spi.

Im on 0406.

Are OCZ selling sticks with poorly binned chips? If the sticks wont do stock speed on stock vdimm, I would RMA them.

[angelreaper]

Some one crossflash P6T Deluxe V1/V2 to RAMPAGE II EXTREME? I see no another way to good support for Xeon

I'm pretty sure I read somewhere else that if you are running RAM sticks in all 6 slots, on some boards you have to raise from 1.65v to 1.70v due to drop in voltage when running all RAM slots.

I really want to know this as well...

[McBacker]

Formann,

Yes. OCZ Platinum XTC 7-7-7 1.65v ( 3 x 2GB )

RMA would take a lot of time...

Can u try Linx and report back?

Also, can u post the BIOS settings u are using? IOH, ICH, VTT, QPI/DRAM, VCore...

Thanks.

LinX 0.5.9 failed after ~1min with anything less than 1.7v

I ran LinX @ 3400Mhz since my Hyper212 takes a beating in LinX.

1.20 vCore
1.31 QPI/DRAM
1.20 IHO
1.20 ICH

VTT on i7? Did I miss something?

Somehow I dont think OCZ are using LinX/Linpack when they are testing RAM.
Or... maybe the mobo undervolts? Asus Probe doesn´t report vDimm, so its hard to say.
Maybe we should check with a multimeter.

In light of this, maybe it was the RAM failing @ 219x21, and not the CPU. Sure would be nice with another 100Mhz for benching

[McBacker]

Formann,

Thanks for reporting!

Good to know I'm not alone on this =]

Btw, VTT is CPU PLL on P6T.

When I was looking for vDimm reporting in Asus Probe I found something strange that might be a factor in the throttling issue.

Asus probe reports CPU temp to be 8c higher than core0 in RealTemp 3.0

RT: 72/73/67/66
Probe: 80c

It wouldn´t be too far fetched to think that the "throttling monitor" is using the same sensor reporting as Asus Prome.

If I get the time i´ll do some testing later on. Maybe some of the throttling we´re seeing is because of the mobo thinking temps are exceeding 90/95/100c ?

bump up your QPI to 1.35 and keep vdimm at 1.66 and if they still failed, test one stick at a time and see what happen. few weeks ago I was pulling my hair out trying to figure out why I coulnd't get a post with 12GB, only to find out my P6T v2 board was defective to begin with, you can see my post at OCZ forum here: http://www.ocztechnologyforum.com/fo...ad.php?t=55657

I have tried all the way up to 1.4 vQPI.

Testing the sticks one by one is too much hassle. I have no trouble other than the sticks needing 1.7v setting in BIOS, and thats only for 100% linx stability. Prime and all other programs are fine even if I run 1650-1700+Mhz 7-7-7.

Who knows, maybe 1.7vDimm in BIOS is undervolted to 1.6v
I assume Asus would make absolutely sure its not overvolting, so a little undervolting would not surprise me.

TurboV reports vDimm, Dram reference, QPI, CPU, CPU PLL, ICH PCIE, ICH, IOH etc etc. I dont use it for overclocking but for checking voltages its great.

Got the P6T standard but its the same on deluxe.

How do you get it to display actual voltages?

My TurboV only show the settings.

hi all,
i'm a new in this field so forgive me my qustions.

With the default speed of the CPU i can put my ram to 2000Mhz.
but with this current speed the max of my ram speed is 1683.
the next speed is 2000 windows does not boot!
i don't know what i have to change to make it work


any help?
and also any advice to tweak these setting, i will be glade
