Nevermind it works now
Had to use another version af afudos and i found the right command. Flashet the board with the 0006 bios and the two settings im was missing is in the bios now:D

That video was rather low resolution, but on the screen it appeared to read 234 X 17 = 3.978 GHz. If so, then why not just do 200 X 20 = 4.0 GHz, which is what I run 24/7, nothing special.Quote:

Hello friends .... back from the "dead" ..... how is the sceene on P6T v2 ?
Thanks,
J
EDIT: Cross-flash ???! WOOWWWW what are you guys "cooking" men !!! :eek:
Can some one give me a short resume please ? ;)
I'm running 4200mhz now, 21*200 @ 1,33v HT on (1,33v qpi, 1,14v nb), and it's rock stable.
Tested 50 passes linx and 8h Prime95.
But I want to go higher, 4,4 would be nice but its hard to get stable.
I tryed with cpu voltage up to 1,43, qpi 1,375, NB 1,22 and it fails after ~20min linx.
I have the memory on 9-9-9-25 @ ~1680mhz and it is specced for 8-8-8-24 @ 1600mhz so I don't think they are the problem.
I'm using i7 920 D0, P6T Deluxe v2 and Corsair dominator.
Anyone have any suggestions?
Or should I just up the cpu voltage more and see if it passes?
How much qpi voltage is considered "safe" for a 24/7 clock?
Im running 4600 mhz right now on h2o:)
220*21 vith 1,45 vcore, 1,35 qpi/vtt, 1,24 nb stable for benching 3dmark and superpi.

I asked because in the future if ASUS stop support for P6T Deluxe to know if I can put BIOS from P6T Deluxe v2 or P6TD Deluxe.
Elsewhere I'm not saw someone being cross flash v1 in v2.
I know to the contrary from you.
For now 0007 works fine for me.

Any P6T Deluxe bios you can download directly from the Asus site will have problems with Turbo throttling at full load when pushed hard. If you don't want Turbo throttling then you need to use one of the special bios versions like 0006 for the v1 or cross flashed to the v2. Asus continues to work on more special bios versions for other boards in the P6T family.
AH OK, Thanx m8!Quote:

I guess it's the missing floppy support. That's a rather stupid bug. I don't see any sense in dropping floppy drive support, they would rather not put the controller on the board and save a few cents in the first place instead of deciding "Oh, we're just not supporting it anymore..."Quote:

I diddnt find a thread for the p6t vanilla or the p6t se, so I guess its ok to use this one.
I just bought the p6t se and im having issues with my xeon w3520. It needs 1.36 core voltage, 1.35 qpi and 1.88 cpu pll voltages to be stable at 4ghz with ht on, lowering any of those voltages causes prime 95 to crash after a while. When I read posts here and on other forums I cant seem to find another D0 that takes this much voltage to be stable at 4ghz, especially the qpi and CPU pll voltages seem high for 4 ghz.
I run the memory at low speed with relaxed timings and I use the 21x multiplyer. Using the 18x multiplyer the board does 205+ bclk using 1.20 qpi voltage so the board should not have a problem with 191+ bclk. The cpu when running prime does not get hotter than mid to high 70s with my TRUE so that should not be an issue ither. All voltages exept the above mentioned are kept at the suggested minimum/default.
Does someone have some ideas where my system is failing or is my w3520 simply totally wank?
http://img76.imageshack.us/img76/848...0earlytest.jpg
A small update
Two things seem to have been the issue. The first was my not so flat TRUE wich made the pressure on the cpu uneven, lapping it made cpu pll voltage over 1.80v unnecessary.
The second was the loadline calibration that seem to be on when using the default setting. My cpu diddnt like that one at all, lots of more vcore seem to be needed. With llc off 1.312v vcore (load) is fine for 21*191, qpi voltage still have to be over 1.325 or prime will go banana sooner or later.
My xeon dosnt seem to be a gem but now at least its in line with what you could expect from a DO
Would anyone please be able to point me in the direction of the 0006 bios (and possibly a guide for the crossflashing) i would be very greatful :)

damsxx: Post some pics and some more info. Try enabling EIST / Speedstep. How much can you overclock before the multi starts to drop from 21.0 at full load?
If your multi drops below 21 at idle, that is not turbo throttling. Adjust the Minimum processor state to 100% in the Control Panel -> Power Options to disable that feature.
What does CPU-Z show for bios version number in case your flash didn't go well?

Oh man. I had been wishing I'd find something like this bios for a while. Can we get someone to consolidate the important info such as the bios file links, the cross-flashing instructions, and model compatibility into a sticky. I'm sure there's gotta be thousands of people who could benefit from this but its hidden away impossible to find. I didn't know it existed until someone mentioned it in another thread on a different forum. I had assumed any bios would simply be released on asus's website :mad:. I had also been kicking myself because I would've bought a gigabyte or dfi board instead if I'd known about this problem before hand but now it's all good.
I had been running at 20x200 1.2625v 8hr p95 blend stable,now I can run 21x200 1.3v 1.5hr prime stable and counting. :clap:

Turbo throttling is still present. So much for illuminatiASUS' statement on a new fixed bios for us.
There will always be turbo throttling on the generally released bios versions that you download from the Asus website. That's part of the original spec and they don't plan to change it. The special 0006 bios does not have any turbo throttling issues so if you need that feature then that is your only choice.Quote:

@all
Is anyone know how to undervolted CPU PLL (< 1.80v) on this mobo (P6T/D Deluxe /v2).
i read it many times before, that undervolting "CPU PLL" might help in overclocking (lowering cpu temp thus gaining stability on 24/7 use oc. NOT in xtreme oc cmiiw).
& i eager to try it my self.
please enlighten me ( or send me a hacked turboV :D:D or special "undervolt" bios :D )
thx b4.
So what exactly does 0610 for the V2 resolve? I don't know if its worth the time to flash from 0504 (which has not given me a single issue thus far).
No real clue, aside from the G15 keyboard issue.Quote:

Anyone else experienced that phenomenon?
Edit: 0610 fixes the missing floppy controller support of 0606 too ...
I read that too. I guess it would take a hardware volt mod to shift the voltage down by a few notches compared to what you set in the BIOS. I'd do it, actually, if someone figured out which capacitor or resistor would ahve to be changed.Quote:

Doesn't the Asus P6T Deluxe allow you to take CPU PLL down lower than 1.800v?
The UD5 starts at 1.300v and goes right up to 2.520v I think it is.
It was on EVGA forums that I read lowering CPU PLL can actually help to make your o/c stable, as I was having difficulty getting my 4.2GHz profile stable, so I tried using 1.300v CPU PLL, and it sorted everything out.
::edit::
Here is a screenie of my stable 4GHz o/c:

No it cannot (go lower than 1.80v)....maybe in the next bios patch :DQuote:

btw i wonder, it cannot be me ALONE (hope so) who like to have option for lowering CPU PLL..right ? ...or.....:shrug:
Out of curiosity to e_crush and the rest, do the Gigabyte X58 boards have Back to back CAS delay in their BIOS? I don't think it would be a good tradeoff if I had the lower CPU PLLs instead of B2B CAS...
AFAIK the ASUS boards were the only ones to support setting B2B CAS...
Else I'd be eager to try Gigabyte. The dirt cheap GA board in my second PC is a really good one for it's low price.
@amurtigress
I dunno, i never had GA's mobo before. Maybe you should ask mr. Bluntsmoker for this..
But we human, tend to be greedy,don't we? So it would be nice to have those two option in our beloved p6t series....do you agree?
Oh,btw..since you mention it. Will you tell me what is the optimal number of B2B CAS for 8-8-8-21@1600mhz..is there any formula for this option? Or maybe "auto" is good enough?
===================================
@all
Anyone care to tell me, the absent of <1.8v (on cpu pll) is caused by hardware limitation or it's only matter of time for us to have it in the future.
I love the P6T Deluxe :up:
Despite few shortcomings itsa nice mobo produced a max 230 BCLK with my 920 D0 just to boot in to windows, max stable BCLK seems like 225 BCLK though I guess it very from mobo to mobos...
Still looking for a way to reduce the PLL voltage from 1.80 as theres no option in bios :mad:
And any info on the proper clock skews for the 24/7 setting would be much appreciated. ;)

12: Memory bandwidth decreases to what you'd expect of a dual channel system. About 6-8 GB/sec
I am using a value of 4 these days.
I read some newer ASUS S1366 board has the value set to 12 fixed. I think it was in an article on the Rampage II Gene or so...I seriously wonder if that board loses bandwidth just as dramatically.
CPU PLL voltage:
There are two possible scenarios: The voltage controller chip for the PLL uses Voltage ID pins controlled by the BIOS. However, I cannot tell if 1.8V is the lowest that it can be programmed to, or if only the BIOS alone is preventing us from setting lower levels.
Second possibility, the analog part "Behind" the chip can be manipulated by adding a resistor to decrease the voltage by 0.2V or so, so 1.8V would refer to 1.6V on the board.
Either way, we are left guessing.
Hi there too! mr amurtigress :up: :DQuote:

I have been testing it too (playing w/ b2b) what i found is identical w/ yours finding and madshrimps article ( http://www.madshrimps.be/?action=getarticle&articID=940 )
but i wonder can you set yours b2b to < 4?...
mine (P6TD), "4" is the lowest number and "0" is the greyed number if we set it to "auto"....,at least... "0" & "4" i think is the same (bencmark result) as you mention it before.
and Dreaming it too...Quote:

@all
about clock skew...
mine set to 100ps (CPU) dan 0ps/normal (IOH)..my logic are (CMIIW please) :
As we overclock, the cpu (signal) will run/arrive faster than the rest of the system,,,so i delay it to making it "harmonious" :D :D with other signal (memory, pcie, ect...maybe..:shrug:)...my bencmark (wprime, vantage&06 cpu test, super pi...you name it) result is showing most stable (not faster) in this setting....making it >200/0 will make result (slightly) worse...or 100/100...200/100...200/200...will make result tend to inconsistent.
i never test it for oc stability ... because i my daily oc is only 3.927@1.224v (see what HSF i use to figure my "WALL" :ROTF: )
ps : if you already found my "wall"...(beside my knowledge and skill of course :D)....now you know why i most interested in "undervolting" LOL :ROTF: to save money you know....:rofl:
...at 4.28@1.288v it will BSOD in linx if the temp go to beyond 93c (i think..saw it many times just before BSOD)...but never hang in daily use / gaming though...still i don't like it....and trying to overcome it without buying new HSF...(but the upcoming NH-D14 is tempting me.....http://www.noctua.at/images/computex...d14.jpg....and or the prolimatech megashadow)

E-Crush,
as for making signals harmonious as you say (snychronizing) this is basically a GOOD idea. For example compensating longer signal runtimes to different RAM banks...
However I think in THIS case it is about avoiding signal interference by shifting them slightly.
A huge problem is for the 20x multiplier of our beloved 920s that so many signals derived from BClock are in exact sync. So rising and falling signals broadcast an electromagnetic pulse into neighboring traces on the board that run signals in sync. Flank meets flank and spike amplifies spike.
No, I gues sthe clock signal delays/skews are here to AVOID perfect synchronisation and thus spike adding/amplifying....
This whole thing is even more important on our previous S775 systems with it's rather analog AGTL+ bus
@amurtigress
Thanks for your explaination.
It will be a great addition for my knowledge
Hi thanx mate, sorry for the late reply, thanks for the infos and please do let me know if you can find any more useful articles, Im using 100 skew for CPU and normal for PCIE now but dont see much difference though. Therefore still in doubt what shoud settings when raising BCLK.Quote:
