Asus P6T Deluxe Discussion Thread

[ben805]

However, my PC froze before I could get the screenie.

It is because now you're running at TRUE OC speed. Therefore, you'll need to up the voltage accordingly to keep the higher OC stable. Anyone who get to test this modded BIOS need to keep that in mind.


Before the modded BIOS With throttling, my previous 4.40Ghz @1.40v (210 x21 in BIOS) = 4.20Ghz (210 x20) in reality after being throttle down. Now with the modded BIOS, what I OC'ed is what I get, therefore, the extra 200mhz that I gain needed 1.47v to be prime/linx stable, which is to be expected. As uncleweb stated in the warning document in the BIOS package, use this modded BIOS at your own risk, people need to keep an eye on the underload temperature and don't blame anyone if one get too excited and end up frying the board or the cpu.

I hate you uncle! You do this just about when I sell my Asus P6T V2 mobo and get an EVGA X58! Not fair man! You should have done this 3 weeks ago. I hate you man........j/k

But I am already doing 4.4Ghz on my evga...so, I am good...

I tested the EVGA x58 and returned it 3 days later, maybe I had a defective unit but it really sucked! I'm just glad I stick around with the Asus, now with this modded BIOS a good board has transform into a great board as uncleweb stated!

Hi!

I would like to try it in my RIG also... can u send it to me?

Thanks!

Hello unclewebb,

I would like to try it on my P6T-Deluxe mobo.

Thanks a lot!

McBaker: Can you post a screen shot of your computer Turbo throttling? That's when the Calculated Multiplier starts dropping below 21.000 at full load. If you are at 4 GHz with 1.25 volts then it's not likely that you are experiencing any turbo throttling so you don't need this bios.

Post a screen shot of i7 Turbo and CPU-Z while running Prime95 or LinX.

Thanks for the information. 2 questions:

You say you don't have any problems 'until now'. Does that mean you are having problems or are you saying you are not?

If I enable the XMP profile on my mobo for the memory, it sets the QPI/Dram to 1.35v and the DRAM voltage to 1.66v. When I use Asus' TurboV to monitor the QPI/DRAM voltage, it says it is 1.375v. Since there is no way to check in the BIOS what the current status of the QPI/DRAM voltage is reading, I have to rely on what I set it to (or in this case what the XMP profile sets it to).

What should I do?

No i don't have any problems at all with my settings. Personally i am not using XMP profile but i set QPI/DRAM voltage and DRAM voltage manually.

If Asus Probe says 1.375v then maybe you can try and set QPI/DRAM voltage to 1.325v in Bios and see if Asus Probe says 1.35v then.

I set it to 1.3v and it still register 1.375v. It's weird.

Here is a classic example of Turbo throttling at full load.
PM me a screen shot like that and I will be happy to share this beta bios. Testing is still in progress.
We have to keep things low key so Asus will be encouraged to release this fix for the rest of their P6T line of motherboards.



Thanks greenblood82.

[infected_]

is there gonna be a bios for P6T (regular) that also doenst do turbo throttling ? and maybe when?

thanks,

[unclewebb]

That all depends on Asus. Hopefully some positive feedback on this forum will encourage them to release a few more of these for the rest of the P6T motherboards.

Juan Jose (JJ) is the Asus rep and has just joined XS. If this is an important feature to you then let him know.

greenblood82 is new to XS but doesn't have posting privileges yet so I thought I'd post how he made out.
Looks like another happy guy with the new 0007 bios.
Interesting observation about what Everest reports.
------------------------------------------------------------------------------------------



Hi there it's me again,

I just flashed the new bios and did some testing.
I upped the vcore a few notches higher than before and let LinX run for half an hour.

The result: no throttling at all. Multiplier always stays at 21 when under load and thats with higher vcore and higher temps than before.

One thing I noticed is that everest now shows the power value of the cpu at about half of what it has been before.
With the old bios it was around 90 watts under load and now it reads around 46 watts. So I think they modified the 0007 bios to trick the cpu so that it thinks it's running at half the power and thats what makes it not throttle anymore.

Probably so, Mine is also reading half the value at only around 65W underload instead of 130W where it usually display with previous BIOS. I'm curious what the R2E would display with the throttling turned off...

If I remember correctly, the throttling kicked in base on a combination of parameters, in everest the motherboard temperature is constantly below 40C under heavy load, about 10C lower than before, so I think this modded BIOS probably changed a combination things to achieve this.

thanks unclewebb. already sent him a pm.

[rfisher983]

I'm thinking of going with this package:

http://www.newegg.com/Product/ComboD...t=Combo.203779

any thoughts? Also, where can I get my hands on this beta bios =)?

[unclewebb]

rfisher983: PM me a screen shot of your CPU turbo throttling and I will send beta bios 0007 your way. This bios is only designed for the v1 boards. Cross flashing your v2 board with this bios is at your own risk. You might want to contact Asus and ask them to release a few more of these bios versions to cover the rest of their P6T motherboards.

The contact info for the XtremeSystems Asus rep is listed 3 posts before yours.
Nice package by the way that you're looking at.

[ben805]

This modded BIOS has been rock stable so far, no problem whatsoever 10 1/2 hours into Prime at 4.40Ghz @1.47v, 21x multiplier is still sticking. Check out the unusually low CPU power usage and the Motherboard temperature from everest.

[unclewebb]

ben805: You have clearly proven that the modded bios is a keeper. Time to share with the masses.

Enjoy!

59.31 watts for 8 threads of Prime at 4.4 GHz and 1.472 volts is a hell of a deal.
Maybe they'll start putting these things in laptops.

[003]

I'm curious can anybody check the reported power usage on a different brand of motherboard that does not turbo throttle?

[unclewebb]

For comparison, xpatar on the i7 Turbo thread posted a screen shot of Everest when he was hitting the Turbo throttling wall with the previous bios.
It showed 125.50 watts when he was at 4.0 GHz with 1.464 volts while Turbo throttling.

http://www.xtremesystems.org/forums/...7&postcount=80

rge also posted some nice numbers for comparison here:

http://www.xtremesystems.org/forums/...52&postcount=5

With a Gigabyte board and an early bios, he used to start to turbo throttle at about 110 watts according to Everest.

After they fixed that, he was pushing 224 watts with 1.49 volts at 4.3 GHz according to Everest with his i7-940.

I haven't found any information in the Intel documentation concerning CPU watts so I'm not sure what this number really means or how a bios can manipulate what is reported.

[xpatar]

What makes me wonder is that turbo throttling happens only with 21 multi.
It doesn't happen if you use the 20 multi which needs higher bclk values and more voltage in order to achieve a decent oc. That results in higher power consumption, higher current usage but no turbo throttling. I managed to achieve a stable oc @ 4.2 GHz with no turbo throttling but that was due to better cooling which resulted in lower temps.
http://www.xtremesystems.org/forums/...&postcount=103
What's really going on with 21 multi?

[unclewebb]

The 20 multi is not using turbo mode so no turbo throttling.

An i7-920 has a default multi of 20. It can only go beyond that with the help of the Turbo boost feature. When you select the 21 multi in the bios, it automatically uses the turbo feature of the CPU to get that +1 boost from 20 to 21.

[xpatar]

I just pm to illuminatiASUS.
Many thanks to unclewebb for his great work on that issue.

I love this modded BIOS...best ever release by Asus! yea the low CPU power usage is funny, in reality it was probably closer to 300W.

[The Watcher]

thanx goes to the creator and all that has tried and share it with all of us.

[Earlstreetblue]

I have just got round to using another P6T Deluxe board I purchased around the time they first became available here in the UK. It has the 0703 bios rev installed. Now I've had it running for a few days now without any specific problems as such, apart from having to disable Express Gate.

Would updating it introduce any problems that I'm not experiencing at the mo, other than Express Gate. I'm just curious to know before I do, lol.

Also looking at the Asus site, I find no mention of this bios either.

Agian a BIG Thank You to you Kevin for spearheading this. I can confirm that the new 0007 BIOS has solved the throttling problem on this board!!

I almost gave up on this board and was about to try other alternatives. If it was'nt for this MB being so rock stable since day 1, (except for this the throttling issue), i would've jumped shipped much earlier on. But now all is good - absolutely stoked.

Again, thanks to Kevin (Unclewebb), Ben, rge, Movieman, and all the rest who stuck it out with all of us.

ps. what program do you use to check for wattage readings? How much watts would the 920 be pulling say at 4.4ghz 1.38v?

[Kane]

Awsome that the throttling problem has been resolved. Hoping for a similar BIOS to the P6T "Vanilla" motherboard aswell.
