Asus M3A79-T Deluxe

[Mechromancer]

Well....lets start all over. Ok so we got the Version 803 BIOS installed and it works (to sum up the last few weeks of discussion).

[Darknight]

is more stable?
or 703 is better?

[Mechromancer]

According to my own overclocking and testing, 803 is MUCH more stable than 703. I'd like some confirmation from several other users though. Get on it people!

[Darknight]

ok..thanks

I will try

[Barr3l Rid3r]

interesting findings, Coon and quiet couldn't work properly while Q-Fan is set to Enabled, it jus shifts the ratio but it doesn't change vcore at all..

After turned Q-fan off (PC health monitor) CnQ worked properly giving me.


4 stages.


idle

Estagio 1 @ 1Ghz 0.99V




Estagio 2 @ 2.25Ghz 1.15V




Estagio 3 @ 2.9Ghz 1.26V




Estagio 4 @ 3.7Ghz 1.53V

0803 recognized my Phenom II x4 955 BE
but keeping VCore setting in BIOS to "Auto" (1.456) , which is way too high

Whats the max NB frequency and cpu frequency u can attain using 1.42V/1.30V (NB)?

Why are u overclocking the HT and not the NB? HT doesn't bring any gain to performance just instability.

I see on the Asus forum there is a Beta 0901 BIOS out now. ftp://ftp.asus.com.tw/pub/ASUS/mb/so...3A79-T_Deluxe/

I don't use Beta's and there really isn't any information on what it does. But it is from Asus, so I'll wait for the official release but posted the link for anyone that wants to try it.

[Daveburt714]

Thanks for the heads up Stoner133,

I'll be the guinea pig...

** EDIT ** Well, I saw it up there earlier when I was at work. It's gone now though...
Guess I won't be trying it.

[MadDias]

my 955 arrived today.
booting into vista x64 at 3.8ghz/1.35v is very nice
but i have to work on stabilty... prime95 bsod´s after about 3mins (uncorrectable hardware error has been detected)
i just downloaded the 901beta bios. will try it when i get up, in about 8hrs.

edit: is the 901 really a beta bios? it´s not flagged or named anything like "beta" on the ftp site. will see how it goes in a few hours.

[Stoner133]

I would assume that since 0901 isn't listed on the normal download site it must still be a beta. I just checked again and it's still not avalible from Asus USA web site.

It isn't listed on the global site either, but the BIOS History contains this:

[ 0901 ]
----------------------
Fix the problem that CPU Vcore might not drop to appropriate voltage when Cool'n'Quiet actived and Q-Fan enabled at same time.

It seems that it's just a quick fix, no major improvements.

0803 Bios and a PhII 955...anyone else seeing temps that seem higher than they should? I have mine under water, 1.375v ant 3.7Ghz thus far (just started OCing) and its already at 50c. That seems high to me.

Check the thermal paste and seating of WaterBlock,, i know its a pain but that may be more than a little higher than normal @ only 3.7ghz.@ 1.375volts

Hmmm 720BE there is a Temp differance in Bios using 803 vs 703..

(0030 X3 to X4 bios) I use 1.62volts on my 720 for X4cores @ 3700mhz. Idle in Bios is 32c

56 -60c is thermal cut off/protection if i rember correct.


Bios wise,,

803 is the most reliable and recomended for 955,, The Bios Does report Higher Idle temp for my Tripple Vs the 703,,Ive read other people with 945/955 have slightly higher temp too.

Also 803 Bios my 720 @ 1.64v @3900mhz/2600nb it shows 30c in Bios and In Vista im @ 27c. i checked my W/B with thermal probe and its 22c. My chipset is also 22c. So id say the Bios is ramping up the temp .

Im using water too.

The 0901 Bios is basically CnQ optimazations and C1E update. It seems to work now with CnQ but offers nothing More. When its made Official it will most likely perform same as 803. Im Back on the Official 803 after trying the 0901 this morning. There was no gain for me . CnQ does work with C1E for the most part though. Since i dont use CnQ ill stick with 803

[ecat]

gOtVoltage, thanks for the update, I'll stick with 803 for now.

[gOtVoltage]

Yeah 803 is rock solid,,

Hhaaha now i think ill turn me 720 back into a fourcore lol.

. Mod Bios seems to be a hair buggy in doing the 4xdo.

Ive found that AHCI is unstable with the 720Mod bios(0030) and it likes 533/667/800 divider the best, .. also my 720 likes the 15x multi and 18x multi when using 4cores. Hopefully ill be able to get more than 3680mhz.

also using +4 ACC not Auto(auto works to get me booted first time .Then to achieve 3.68ghz on 4cores i need +4. Once i set it i forget it!

[MadDias]

i´m on the 0901 bios right now.
i hoped this bios would also fix the "auto" cpu vcore error.
when the cpu vcore is set to auto it´s at 1.47v. so i have to manually set 1.35v to get an almost stock vcore (cpu-z reads 1.37v).

i still get no boot at 4ghz, same behaviour as on my 940... slowly i´m suspecting my psu, cause it´s a hard reset no bluescreen or error message, just a power down and then a reboot. i´ll tear apart my old rig and test the ocz gxs 700w.

[gOtVoltage]

You could be pushing that PSU ,,i Max around 4.ghz with the 720 running on650watts.


My auto volts @ 1.46v CPU and 1.20v NB when i use VDD @2.8v ACC +4 all cores. CnQ disabled.

Same on 803 and 901.


Note: 3x to 4x 720,,
Im keeping my 720 a 3core because the Mod bios is too buggy even when running with out ACC enabled it has several bugs.

Quick question:

Is it possible to change the characteristics of Q-Fan ? I know there are the 3 basic control settings but what I'm after is something like my old 939 dfi lanparty ultra where I can specify the temperature at which the fans are driven to 100%. Water cooling keeps the temperatures down nicely and Q-Fan is not really designed around this. I've been messing around with various options but it would be nice to give my fans a bit of boost without resorting to external controllers .

[gOtVoltage]

You would set the Fan speed to the highest level or use Disabled for Max fan speed. I dont believe you can preset the Temp bump up speed.

Thers no option to do so ATM.


fan warning speed i keep disabled. Im on water.

Mine runs solid with 4cores on the MA790FXT-UD5P. I run 3.8ghz 1.52

That's what I thought Thanks anyway.

I can't get SpeedFan etc to control the speed either, another quirk in the Asus bios. Grrr, come on Asus, your bios is good, just a couple of little tweaks and it could be great

Oh well, back to trying to interface the mb fan header with my t-balancer... just wait for the big bang (I know I can use a 'software sensor' with the t-balancer but that means relying on software :shudder: )

Official Beta 0901 ...I believe it only works with the Beta ..Speed Fan didnt work the best in 803.

Select the Os your using then try o901.....Qfan is 99%fixed in this Bios or not as buggy as 0803

CHARGED .. saving for a AM3 mobo ...The UD5 is AM3/DDR3 and M4-T deluxe..Ive noticed that lots 720X3's do X4 the Best on AM3 Mobo. Maybe has to do with running DDR3 IMC ,,using DDR2 is just palin buggy with 4cores unlocked

By fixed do you mean adjustable ? I'll probably give it a try.

Meanwhile, direct MB fan header to t-balancer analogue interface Not perfect, not quite linear and probably only working through pure chance...



.. good enough for now and not bad for someone with only cookbook electronics skills Testing nervously and waiting for it all to go bang

Why are u overclocking the HT and not the NB? HT doesn't bring any gain to performance just instability.

Sorry about my sign , it's a typo
It should be "NB 2.6GHz and HT 2GHz "

NB 2.6GHz is the max stable NB I can reach with my 955BE on M3A79-T DELUXE
NB 2.8GHz is NO POST/BOOT even with 1.35V NB voltage
