read that, the thing is that how does it come into play with our computers. What does it do?
Thanks by the way.

Some of my major issues with the board: http://img221.imageshack.us/my.php?image=clipboard02dd7.jpg
thank you oliverda
1.40v in Bios = 1.46v can be from what ever the VDD is set to if on Auto..(2.5v vdd up to 2.8v vdd..)The Higher you go with VDD the Higher it raises the Vcore for both CPU/NB
Example :
2.5vdd + 1.40vcore = 1.45v
2.6vdd + 1.40vcore = 1.465v
2.7vdd + 1.40vcore = 1.482v
2.8vdd + 1.40vcore = 1.50v
Those are not exact but thats how the Auto VDD function works.. i usually start with 2.5vdd and set the Vcore manually and even then it will ADD Xtra vcore...Just how this Mobo is...
As for the prime with 1.030v load it probally a glitch with reading the Diode..
I use (CPU-ID Hardware monitor) and (CorTemp).. seems the best compared to Speedfan which dosnt read and AMD Monitor which can also be buggy...
Im still testing my Max for above 3.52ghz ,, Waiting for Replace ment Cooler to arrive...Since i sold one of my BIX !!!'s i decided to add a 120.3 Feser,, I know i got the Cheap 17mm one$99bucks ...i just had to try it...I have a PA 120.3 somewhere in the Attic but am too lazy to check.. Everything went into attic which wasnt attached to a running rig .:D
P.S. Everest reads things fine..The ASUS mobo does read 10c higher overall... ..But then again full load on 3.2ghz and Air @ 63c dosnt surprize me if you subtract 8 - 10c it would yield 53c with 1.46v seems kinda Kosher to me if Prime is 100% and no crashes after a few hours.
Great job Gotvolt!!
i was curiosu what the VDD did. I am currently running mine on auto. I didn't know what it did, and adding more and less didn't appear to give me any extra boost.
Is VDD only used to "bump" vCore.. or is the voltage actually used for something else, and the vcore Bump is just a side effect?
Ton
I want 1.40V at load and at idle as well. It overvolts the CPU at load like hell. :shakes: I think it is not normal.
I know that the 1.030v is a fake value. I would like to show that when the CPU temp (which is incorrectly reported by the mainboard) reaches the
approx. 68-70C degrees the system automatically switches back the CPU's multiplier to 6.5x. :confused:
Thank you for the link oliverda. So if i increase VDDA the circuit might not fall behind more frequent with higher clocks.Quote:
The oscillator generates a periodic output signal. Assume that initially the oscillator is at nearly the same frequency as the reference signal. Then, if the phase from the oscillator falls behind that of the reference, the phase detector changes the control voltage of the oscillator, so that it speeds up. Likewise, if the phase creeps ahead of the reference, the phase detector changes the control voltage to slow down the oscillator. A low-pass filter smooths out abrupt changes in the control voltage; it can be demonstrated that some filtering is required for a stable system. Since initially the oscillator may be far from the reference frequency, practical phase detectors may also respond to frequency differences, so as to increase the lock-in range of allowable inputs.
Its like the how VID works just adds more to the Base Voltage and helps keep the Voltage supply up when go high CPUclocks..I stumbled accross it by shear luck one day;)
I even experianced the Thermal shut down ,, i tested with High than Normal Vcore and Max VID..i mean Above 1.75volts total and i could make it happen..This Mobo reads 10c higher than Normal so any temp range below 65c can easily read 70c+ when its not suppose too..
As for the VID or Volts being 1.40v consistan youll have to play with each VDD setting and adjust the VCORE for CPU untill you have 1.40-1.42v under load ... Using CPUID hardware monitor and Coretemp will read VID and VCORE close to accurate..
Its like a game in its self just to get what you want Volt wise with the SB750 chip set .. SB600 was easier to set i believe..Then again AMI is little different from settings in AWARD...Thus i give props to AWARD bioses..
Yup,, it does help alot when High Oc is involved especially when running High NB too.
youll need to adjust each setting till you find the sweetspot..Trust me its not as easy as it looks and can be time consuming ,,Just like finding good Timing on ram i do one setting at a time and write down what it did then try another untill i get what i want:up:
NEW UPDATE 11/2/2008
ASUS website has 504 BIOS ready AGESA update...
I just downloaded it ...Trying to look up info if anyone else has tested/tried it yet....
Well mine will be here tomorrow and i will post some overclock with a 5400+ BE
Hahaa, partyfoul im bad,,its just a reminder:ROTF:
I have done some research on this bios option and discovered some things. First, the majority of web descriptins of CPU Tweak say it is part of a performance solution for the TLB bug fix. Supposedly, selecting this option without the TLB fix option enabled causes increased cpu heat under load.
It was enabled by default in the ASUS M3A79-T bios so I left it there prior to my research. Under heavy load, while under water, I was getting about 47.5C - 49C in core temp. I have been thinking this was a little high for only 3.2 ghz.
After disabling CPU Tweak in the bios, I noticed that the red circle around the green button in the upper-right corner of AOD was gone. I then decided to test cpu temps while running OCCT-a great high load stability test program. My temps dropped on average 4C !!!:up:
YMMV, but disable this bios option and run a high load test program to see the impact on temps. Some posters here have seen increased performance with it enabled but I have tested it all day and gotten better performance with it off.:D
I was testing the red ring on the green botton in AOD to day and on my Foxconn A79A-s running 3dmark-06 it pick me up 200-300 points on my score by having it on . And it dose make the cpu run hotter but i'am using water cooling so it was no big deal .
I'm curious about this effect too. It's pretty obvious that raising CPU VDD will increase Vcore as well, but what would happen if you raised VDD to 2.8v and lowered Vcore to 1.3. Would that result in a 1.4v Vcore while improving Clock Gen syncronization?
And what would be the effect of that on the PWM section of the Mobo?
Excuse me if I'm a little skiddish, but I killed my last board with the AOD.ini mod to allow higher CPUvid, and I actually have to buy my own parts... ;)
now in the uk, (has been for a week or so)
http://www.microdirect.co.uk/Product...ource=googleps
this internet site is sound, i have ordered from them lots of times, never a problem
I don't understand this eighter dave. Have no clue why a higher vdda results in an higher vcore. Maybe it's just the sensor reading. Noone prooved it with a DMM yet. As far as i understood the wiki page an higher voltage results in an higher frequency and the circuit has to increase the voltage if the frequency is too low. I assume the stock 2.5V are good for stock clocks but with higher clocks that pll will have to do more correction work.
thats pretty much how it is,, use less or more Vcore for your target volt range that you will use...
Ive been testing High Vcore for two weeks @ 2.8vdd + 1.65v = 1.70v for both NB and CPU...This mobo can handle just about anything...Also the Same Voltages were used when i pushed Mobo@ HTT 292 x12 = 3.5ghz while having PCIE/core and HT @ 2.8v while keeping Southbridge @auto ...
This mobo has let me achieve the highest HTT @ 3.5ghz vs other Mobos ive tried..Yes Mobo can be buggy and does need lots of work to tweak. Updated Bioses will definatly make it even better.
The stock heatpipe works great. I had pull it off just to see if it had good flat contact.. After a small tweak of the pipe(not the funnyPipe) i installed the same thermal tape on pwms and used MX-2 on NB/SBchipset ,,thats all i did,, Oh yeah i flashed to newest BIos yesterday and it gives me the same results as the 40x vs 504.
The VDDA voltage doesn't have any impact to the VCORE on my board. It overvolts same the CPU at 2.5V VDDA like at 2.8V.
Overvolt mania by ASUS.....yeah... :ROTF:
Wierd maybe it has somthing to do with what VID range is in effect....
Also iif you raise the Vcore for NB it will raise the VID for both,, since the Vcore of NB can not be higher than CPU it will auto matically raise CPU a step ahead or the same value for VIDs..
Now on the other hand If you raise the Vcore for CPU which will raise the VID accordinly to its vcore value it will not raise the NB value.
When testing all the volt settings,,
i Raised Both CPU/NB volts the same @ Stock Clocks to see what volts = what VIDs up to 1.55vid = 1.65volts .
It seems VDD Rasies the VID value more or sooner when VDD is raised,,Especially under load...
I know its confusing..
Note:
The screen below my VID is 1.55vid for both CPU/NB ,, VDD is 2.8v Vcore for both CPU/NB is 1.65v.. Total value with VDD 2.8v + 1.65vcore(1.55vid) = 1.70volts for both CPU/NB. Im using WaterCooling . on Air or Stock cooling above 3.3ghz you will be limited by heat. These values can be raised to see 1.78v so please go slow..Im pushing well above the average volts. This Mobo and Chip has seen 1.78v+ just because it can.
So far this is my best Oc ,,
My NB@2640mhz is maxed with this ram freqency(for this Chip) so to go higher i would have to use less NB from here on out.
Still tweaking it,, happy for now..
http://i168.photobucket.com/albums/u...hz_1174mhz.jpg
well im happy i got my board today and i tell you this is a nice looking board but its not the black it the brown but doesnt matter ,should i get the Phenom to put in here or wait for the Deneb , if it is the Phenom what one should i go for?
then i think the Deneb is going to go for maybe $300 ,but who knows , i see everyone having some nice overclocks here with the 9950 ,but im also new to the X4's
Plz make some suggestions
Thanks Roger
No one knows for Sure when the Deneb are comming out , i hope people dont think im trying to Hi-Jack this thread , i read that they supposed to come out on Jan 08 2009
Guys, what is your general opinion for the new BIOS?
Has anyone seen better or worse OCing?
Me personally didn't get anything from the new options of CPU Prefetch etc. and I am thinking that maybe I should go back at 04..
I think 04 is more stable...
I had weird blue screens with this one.
With 04 nothing stable as a rock.
message from starfleet, data concurs !!!!

Something new every day with this Mobo...
CPU voltage = 1.67v and Now the VID's read 1.46v with CPU @1.72volts
NBcpu voltage = 1.65v
HTT = 2.8v
CORE/pci-e = 1.30v
SBvoltage Auto
VDD = 2.8v
ACC Disabled.
Some how it looks as ACC enables its self after you hit a certain point i dont know whats going on but this is the Highest Clock ive reach with this chip and Mobo . I thought i was maxed @ 3.52ghz..
Also im using NB@2000 and HT @2000...
I just find this Odd that the VID lowered when i use 1.67volts on CPU but keep NB @ 1.65v...Something is self adjusting :shrug:,,all Values for VOLTS manually set with ACC DISABLED.
http://i168.photobucket.com/albums/u...0HT1_46vid.jpg
Your board seems to use VID's like my AsRock
No offset up to 1.55V just VID's used. Then comes an 0.1V voltage offset + VID's, so max adjustable on a running system is 1.65V here if you can not change the offset. To get higher you must boot at 1.665V. Also tested 1.765V with my 9600BE and it booted just fine into windows.
With an DMM I noticed that the idle overvolt had dropped from ~0.1-0.2V to -0.05V but the difference between load and idle had increased going from 1.55 to 1.565V.
i personally think the 04 bios was better, I might flash to it again. I cant even run my ram at 4-4-4-12-20 with this bios, it wont boot. worked flawlessly with the other bios.
this guy was the same, he was gutted,
http://i278.photobucket.com/albums/k...ndood/1jd5.gif
Hahaa, that vid is sad , funny, and off the wall all at the same time,:rofl:
Good inf JUSTAPOST ,,on the vids..
I used 504 and 403 bioses and i think in the end the 403 is most stable .Even though i can get the same clocks with 504 .The 403 is not as sensitive to the ram going above 1150mhz for my 9950:shrug:
504 booted the same as 403 hot or cold,just is harder to tune my ram even with loose timing.
^^yeah, im going back to 0403 tonight for sure. This 0504 bios sucks!!!
I haven't had any problems with 0504 so far. :shrug:
The HT multi switch works above 10x with 0504. :D
I dont know if this has been addressed in this thread or not because I have not siphoned through all the posts, I am not at the house yet and I am looking for a water block for the mosfets. I am looking a couple different models but I need to know what the exact spacing is between the mounting holes in the board. I am thinking that this one will work if I turn one of the mounting brackets to put the hole in the bracket to the side.
http://i120.photobucket.com/albums/o...vr-as39_01.jpg
I made my own :D
I'll be installing it next week
http://i231.photobucket.com/albums/e...r/DSC02044.jpg
http://i231.photobucket.com/albums/e...r/DSC02046.jpg
Now I just need to figure out how to cool the northbridge :shrug:
I was thinking of using the mempipe holder from M3A32-MVP
I would have to fill the gap between the holder and heatsink
http://i231.photobucket.com/albums/e...r/DSC02060.jpg
http://i231.photobucket.com/albums/e...r/DSC02058.jpg
Is that copper plate you have brazed to the pipes the same plate that comes with the heat sink on the board?
I was thinking of doing something similar, but using the koolance mosfet block and screwing it to that plate.
I just want to see if I can get another heat pipe setup first so if I have to RMA the board, I can.
i bought the koolance one see below:
http://www.koolance.com/water-coolin...product_id=660
then you gotta get the transfer plate which I bought the biggest one they had, I had to grind off a bit at the ends though, it was just a bit too long.
http://www.koolance.com/water-coolin...roducts_id=659
The heatsinks are aluminum on the mobo
I had one of guys at work cut a copy in copper, I made it longer so it covers all of mosfets
The mosfet heatpipes are just glued the NB heatsink and a thermal pad under the heatsink, easy to remove
The NB and SB could be a different story, I destroyed one M3A32-MVP already trying to remove the heatpipe assembly, the TIM was like epoxy when it got cold.
I got to see the inside of 790FX :shocked:
I'm hoping ASUS changed their TIM for NB and SB
OK, I figured it out!
I'm going to use the Koolance block I pictured above and get a piece of copper plate 1.5" x 4.5" and 3/16" thick from online metals, and I'm going to cut it to be exactly like the plate that comes with the motherboard only a little longer. I will then use Arctic Silver Thermal Adhesive to adhere the block to the plate.
You guys think that will work?
Thanx, Lee
well i got everything install , but i do have a question everest is showing me these readings , does this look wrong for temps and volt

Two quick questions I didn't find answers to;
So has anybody has any success running 8GB at 1066?
And if it's not possible is one better off running 8GB with 800 memory instead?
Well running Men. at 1066 may not be the fastes set-up . For me running my men. @ 1000 and 2500 NB/HT linkspeed is faster than running my men. at 1066 2000 NB/HT link speed . I can not over clock my men. hight enought @ 1066 to beat out the 1000 2500 NB/HT link speed setup . Just something to think about .
Thanks guys - you rock - I really appreciate it!
^^ no problem mattias, count on us anytime :)
well i got my 9950 be today with my Zalman 9700 now to work with the overclock for this
Is anyone running this on Air and overclocked?
my memory is running @ddr2 800 so i would have to change this to 533 for ddr2 -1066 ?
With the new 504 Bios, I was able to go from 3.3 to 3.4 ghz.
M3A79-t
so i have to set it to what in the bios? 1068?
Wow how did i miss that Sig... A X2 will not run in 1066 mode...You must raise the HTT to 266 and use a low ram divider to get 1066mhz..
266x2(half divider i believe is 400ram divider so setting ram too 400 and raising HTT to 266 should work...keep the HT @ around 2000 untill you get your ram where you want it..
266HTT and 400ram divider = 532x2 = 1064mhz(1066ram)
I forgot Only Phenoms IMC/integrated memory controler can use the 1066 divider most any Bios ,,unless you have a 2xcore Phenom..K10 the IMC then can access 1066..
If you are using a X2 like in your sig..You must use High HTT to achieve high freqency ram...Youll set your ram timing and the Volts@ the specs of your ram for 1066..
If you dont know what timing to use,,Install CPU-Z and in Memory Tab it will show the timing your curently at..In SPD tab it will show volts/timing to set if your Ram has a EPP setting:up:
Hope that helps ya,
gOtVolTage
P.S. Phenom can run HTT292 with this Mobo,, X2's can run 320+htt..so youll be able to use 266+HTT,, just lower your HT and ram divider till you get to 266htt and 1064mhz on the ram. the Higher the HTT the lower CPU multi you need to set also.
UPDATED,, UPDATED,,
Crap change your sig to Phenom! You had me comfused,,
The info Posted above applies if you cant use 1066 divider or have a X2,,
Set the ram in you Bios to what ever setting is close to 1066 with out going over 1066mhz...The Bios will show exactly what freqency your ram will run(be set at) with each Ram divider if you select manual divider and timing:up:
oops sry i forget to change it i have a 9950BE Phenom lol
Ok Fixed
Its cool been there done that ..
Hope it works.
Your settings will look something like this,,
The higher you adjust the HTTabove 200 it will readjust the dividers to read what your ram will be set to..Keep it at 1066 or lower unless you know the ram clocks above 1066..
Make shure you set the correct volts for your ram to run 1066..some chips have a higher volt value to run 1066 instead of 800. My vipers run 800 @ 1.8volts and 1200 @ 2.3volts. Each Ram manufactur is different when it comes to Volts running 1066.
http://i168.photobucket.com/albums/u...erra/001-1.jpg
ok i will check , ty for working with me
Ok i just checked mine and i have 400 , 533 ,667 ,800 and 1068
First ,,
Set your Ram timing to Auto with 2T Enabled then select 1068....
If that works you can lower your timing after.
Ganged mode usually is the fastest and most stable,,
look for a setting that has Ganged Mode..it will be defaulted to (AUTO)
****Set it to Ganged****..
If that dosnt work then try Unganged..
Note: IMPORTANT
Make shure you Ram volts are set to run 1066.(factory spec of your ram volts)
Make shure your using yellow Ram slots for dual channel mode .You may need to raise your NBvolts some for 4gigz even though your usin two sticks..It puts a litte more load on the IMC/CPU when running 4g's.I only add volts if its not stable
how do i set it to ganged right now it unganged
ASUS Motherboards Now Supports AMD AM3 Processors
M3A79-T Deluxe (BIOS 0504) :up:
DDR3 cannot fit in DDR2 slots can it?
EDIT: DDR3 and DDR2 both have 240pin so maybe they are compatible with each other.
is it normal for the 9950BE 125w to be 50c ?
im cooling with a ZALMAN CNPS9700 and fan is on high and 2500RPM's
3/8ths is a good divisor...all you need to wory about is running your ram at what you want speed wise and that is 1066:D..
AMD's clock totaly different from Intel..so the Divisor can pretty much be what ever ,,as long as you dont exceed your Max ram Overclocks..If you have1066 just stay close to 1066 or lower..If you know your ram can clock above 1066 then by all means try to MOVE the HTT up a little while using the same Ramdivider (youll push the ram higher..In the Bios it will show how much youve gone over 1066 if you choose to do so:up:
For Now keep it simple find out what works and how high you can push your CPU xmulti while using 2000nb and 1066ram..
Then you can go back into Bios once your CPU is Overclocked and look at ram Freqency to see if you can go higher with it..
Takes time to tweak,,Phenom in general( B3) is by all means a nice platform to tweak...It will only get better.
P.s.
I go by the Freqency of my Ram. The Diviser CPU-Z shows is what the CPU and Ram run at for that freqency...youll notice that it will set what ever divisor depending on Freqency ,, ram divider and the Multi the CPU uses..It will change when you change ,,Lower,, raise ram or Lower ,,raise CPUxmulti..
Nothing is wrong in that aspect at all:yepp:
Hey IS THAT IDLE OR LOAD TEMP? sorry for yelling:D
XRodgerX,,
if thats @ Idle check your CPU volts and ACC disabled ..Run 1.35v for CPU and NB volts @ stock clocks then Post a Idle temp..50c is more of a load temp ,,So if its 50c at idle you may need to check how the Heatsink is mounted and or if your giving it too much volts..That ZALMAN can keep it @ 28-30c with 3.0ghz easy @ Idle
idle load is 45C and gaming goes to 50c
Also what is this CPU tweak that you speaking about
Im sry for all the questions this is the best system i have build myself
I dont want to blow nothing up and i have alot of question
The place is awesome not like others you all are very helpfull
also i got this at 3Ghz and i tested it with AOD and it ran for 1hr np
and the temp went to 60c
ok well i dis abled it and now my temps are @ 38c on idle
hey Chicken are you on Air?
chicken patty is on water. ( is in his picture too)
I'm seriously thinking about it for a deneb chip now.
bye the way are you getting corrosion in the loop yet ? if any at all.
well i overclocked it alittle more im @ 3.1 now ,how is AOD for checking to stableness , is it reliable, or should i check it with something else , i know theres alot of programs out there but would you all suggest as you know these cpu and motherboard better then i do , you all put so much time into this and helping me out its just great i cant believe how nice you all are here im not use to it lol
