Asus P6T Deluxe Discussion Thread

[sodina]

since yesterday, the board hangs at boot up trying to detect sata hard
drives. i have 3 sata drives. 150gb, 1tb, 1tb. i am not running them in
raid or anything.

if i disconnect 2 1tb drives, everything is fine.
also if i disconnect one of 1tb drives, everything is fine.
but if try to boot with all 3 drives connected, the board
fails to recognize 2 1tb drives, and hangs at boot up.
its kinda random, sometimes it recognizes all 3 drives, sometimes it only detects
150gb drive and hangs at boot up.

i did enable & disable marvell controller numerous times, but does not seem to work.
this board is giving me nothing but problems.
i doubt its the power supply or the cables as i was using the same ones until 2 weeks ago.
on p5e3 board. i read somewhere overclocking failure could cause this. but it happens at default clock as well.

would reinstalling windows help?
can someone help?

[sodina]

i reinstalled windows and everything seems fine now.
i didnt even install marvell sata driver, just ich10 chipset.

trying to get it stable at 4.0 as i write this.
just hope it doesnt happen again

Errrm, you're having me totally confused. You are talking about the Marvell controller. That one is a SAS controller, assuming you have the P6T deluxe V1 board. You did not mention which one...Else, the other marvell chip on the board is the eSATA/IDE chip.

If that one is having issues with your SATA drives, try them on the ICH SATA ports, and vice versa.

Try increasing the ICH voltage by 0.1V if nothing else helps.

ive been trying to get it stable at 3.8ghz for a while now.
but ive been getting some weird errors when running prime95.

for example, i would pass prime large mode at 1.2v but fail blend mode.
so i up the vcore bit more, only this time pass blend mode but fail large mode.
what is wrong here? how can i fail in large mode with higher vcore when i alreday
passed the large mode with previous lower vcore?
i believe 1.2v should be enough for 3.8ghz because i can boot into windows
at 4.0ghz (200x20) with the 1.18v.

i suspected memory. but im only running it at 1603mhz (pass memtest 5 hours),
which is pretty much the default setting.

anyone wanna shed some light on the situation here?

Hi there,

I think you should have read a bit more of this thread.

The i7 920 requires roughly 1.25-1.3V at 3.8 GHz. That is for a C0 die revision, D0s require tendentially less. My C0 takes 1.375V at 4 GHz (19x211), but would get 100C hot running any flavor of Linpack.

IOH voltage: 1.26V. Less than 1.22 won't work at that speed.

Disable C states in the CPU config submenu.

That should get you in the right direction

[sodina]

upping ioh seems like working.
currently testing 200 x 19 and looks like its stable.
passed prime95 large, blend mode for 6 hours.

cpu - 1.176-1.18
cpu pll - 1.82
ioh - 1.20
qpi - 1.35
dram - 1.66
intel speed step - disable
c1e support - disable
everything else auto

temps are bit high, but its middle of summer and
i am on top floor unit with no ac on. so i dont
think is all that bad.

[Amurtigress]

Sodina,

apparently you're not reading my posts closely, and you are not giving some important information on your CPU, so I'll stop helping here.

Next time be so kind and read the thread before approaching people with quizzical posts.

Bye

[sodina]

i have no idea what you mean.
what more information on cpu? stepping?
it is 920 d0 + p6t deluxe v2

and yes, i did read about last 20 pages of this thread before
i asked a question. there was not much info on bios setting.
it was all about how 21 multiplier getting throttled town to 20
and the modified bios to fix it.

your help? ioh 1.26v is way too high for 3.8ghz.
most of 920 d0 chip achieve 3.6~3.8 with just upping vocre and qpi.

one question guys

can you use the 2 sata ports behind the white pcie slot when using 2xgtx 285 or 295??

does an gtx 285/295 fit in white slot when the psu is installed in the bottom of the case??

pls help

I don't have that kind of card here, but as I see it, those two SATAs were put right next, but left of that PCIe slot to avoid interfering with long cards in a SLI configuration. Hence also the four/six angled SATA connectors at the front of the board. ASUS had an eye on such problems when designing the board.

How come the vcore is blanked out.? If you have some ridiculous high vcore and you cant use it 24/7 then it doesnt mean much imo.

It's doen automatically, try it yaself... there's never ever a Vcore indication in a CPU-Z Validation screenshot... sorry to say but almost everyone understands that a 5Ghz validation is not a 24/7 speed... no idea why you even made that comment...

Good work Expander on that P6T , top job !

Well im just making the point that for me unless you can run it 24/7 its pointless. Sure its a good effort to validate at that speed but i dont see the point if you cant actually use the computer for what its designed to do.

But yeh i dont usually come here for that reason, most of this thread is crying about 21X multiplyer dropping at over 4 ghz and people saying asus sucks because their 2.66Ghz CPU will only run normal up to 4ghz.

I just like to keep an eye out for new bioses or any discovery about the board.

OMFG!

Great job!!!

Can you post your voltagens in bios to get this bblock clock?

Have any of you removed the "top" of the NB heatsink to add another waterblock / heatsink?
If so, what where your results?

I did a quick test with some freeze spray to cool things down and my finger to heat them up. So far as I am able to determine, the motherboard temperature of the ASUS P6T Deluxe V2 motherboard is actually the temperature of the Winbond chip itself. It is not an ambient temperature. Due to its location, it is also highly affected by the cooling layout of the first video card in the system.

In this picture of a P6T Deluxe V2 motherboard, I have outlined the Winbond chip with a green rectangle:



Can anyone either confirm or deny that this is indeed where the motherboard temperature sensor is located, inside the Winbond chip?

I have not added a water block to mine, but I have removed the heatsink and replaced the thermal pad found there with well spread out MX-2. I have also added the supplied standoffs and a 40mm fan to the heatsink as specified in the motherboard manual.

I know I am off topic by not talking about the 21x multiplier. What do you think about the new P6TD Deluxe?

What's the difference between the P6T Deluxe V2 and the P6TD Deluxe?

Intresting, did you noticed any improvements in overclocking or stability?
Or perhaps it wont get so hot that it's a problem even without fan.
It's aluminium right?

The black fins part that screws to the underlying chipset heat sink is aluminum. I think the underlying chipset heat sink is a copper plated aluminum slab. Hard to imagine ASUS paying for solid copper. The 40mm fan is obviously plastic.

Back when I was on air cooling I was not using the ASUS fan and the 40mm fan. I also wasn't using the stock Intel cpu heat sink and fan. I was using just a Mugen-2 with a Scythe fan blowing through it rearward. So I'm not sure how much air either the MOSFETs or the chipset heat sink were getting when I was on air. Probably not much. On air I was running 3.2 GHZ 24/7.

When I switched to water cooling I added both the ASUS fan on the rear MOSFET heat sink and the 40mm fan on the chipset heat sink. I never actually even tried water cooling with out them. On water I'm running 4.0 GHZ 24/7.

I have not noticed any differences between having the fans there or not there, but then I haven't looked for any either. I've been told that the motherboard life would be shortened without either them (or something else to accomplish the same thing).

I'd certainly be willing to add an inexpensive water block to the underlying chipset heat sink instead of using the black fins and the 40mm fan. That would likely cool better than the black fins and 40mm fan do. I may do that. But I suspect it wouldn't make any difference, so I'm currently operating in "why bother?" mode.

What I'm not willing to do is to buy a full cover motherboard chipset water block AND two MOSFET blocks. For the price and inconvenience of adding all of those, I could more easily buy and swap in a new motherboard when/if mine eventually fails!
