This Biostar doesn't seem to have any problems with 18.5 and 19 multis, but the power section can't handle the required v's for very long (over 1.45).
Sounds like it's not that big of a problem, hopefully Asus will give us a bios update soon..

Can't post a pic, but yeah.....it's BIG, covers the first ram slot, and only orients only up or down. I've got one on an EVGA 590/5000BE combo. You can only use standard height ram.....anything taller and you'll need to cut the ram heatsink to get it under the 120. Check out this Sunbeam Core Contact cooler review on Frostytech......Quote:

kinda random but does anyone know if this is the only mobo that will run 4 sticks @ 1066 or do any other boards do it?
There is a supposed limitation in the IMC that only supports 'one dimm per channel' at 1066. I say 'supposed' because some people have successfully run four sticks. It isn't a motherboard thing, it's the CPU. I'm running 4x1 G.Skill 1066 by dropping the ram down in bios and jacking the bus speed up.....1000 ddr2.
All i do is set it to 1067 and 5-5-5-15 @2.1v in bios
has anybody been able to break the 4ghz mark stable for 24/7? Just curious because that is what AMD said this chip was capable off on air.
not I . It craps out with anything over 3.7gig on my setup
ACC is broken also. We really need a new bios.
Now i know why they sent 790GX board with the PII to reviewers

For anyone who may be interested (and doesn't already know, Thanks Ben).
Editing the Preference.xml file for AOD worked like a charm, allows me to go to 1.55v's in AOD and doesn't instantly crash when Bios is set over 1.45v on the CPU.
The Asus 79-T seems to handle these v's just fine.
BE ADVISED: IF YOUR BOARD HAS A WEAK POWER SECTION OR INADEQUATE COOLING DON'T TRY THIS!
The MSI DKA790GX is a perfect example... :shakes:

I am stilling waiting for retailed 940BE here in Hong Kong. I have the asus 79-T already and I love its beefy PWM section. Which bios version should I got for 940BE? If I have earlier bios version, can the MB boot with 940be?
Also if you need vcore higher than 1.5 you can adjust it in AOD by setting the bios vcore higher than 1.5. Then AOD will typically show 1.4x. Then you can adjust from there and use cpu-z to see the actual vcore. That is what I do anyway.
it can boot with the 940 and an earlier bios. i tried it with the 0403 but it was no fun. 0602 works best for me.Quote:

The board eventually shut down (with no damage), I'm pretty sure the PWM section overheated. I was sober enough to take a SS and the only real difference I see is that I had the CPU/IMC @ 1.4v.. :eek: With a +.125 offset for the CPU..
Does anyone know what a safe vid is for the IMC on PhII?
For that matter does anyone know what AMD's stock vid is for the IMC?
If I leave it on auto in bios it boots around 1.125 which seems kinda low...
stock (optimised defaults) vid set on dfi lp dk 790fxb-m2rs/h for PII 940 is 1E (1.1750) for NB (1.8GHZ) and 1.31v (Auto) for CPU.Quote:

The edge of the TRUE line up with the outer edge of the second DIMM slot aand if the gap between the socket and the first DIMM slot is too small the you won't even get a normal size module in there.
I switched over to the SI-128SE and I'm using it with my Abit Fatal1ty AN9 32X at the moment and it just allows my G.Skill PI modules under its supporting bracket:

Is anyone running a water block on this board?
This is my first water cooled system, so I'm not 100% up on it.
The manual for my water system says if the mobo has threaded holes on the back of the cpu bracket, then I should use that to attach the water block, if not, I should remove it, and use the supplied metal 'H' clip.
Which would be better?
Thanks.
[QUOTE=MadDias;3568397]itīs not trial and error here.. even unplugging the psu and waiting a few seconds doesnīt change it. what do u mean with "voltage jacked up high"? i mean acc is of no use if i have to use stock volts to enable it.
what is an extra 450mhz? 3450mhz? or 3600mhz+450mhz? ;)
A few seconds doesn't cut it, you have to turn it off long enough for the power LED on the board to actually go out. What i mean by "having the voltage jacked up" is doing something like booting at stock clock with over 1.55v. Actually a reliable source has told me that anything over 1.475 is going to be more likely to cause instability if clock is below 4ghz, 4.1ghz - 4.2ghz require between 1.525 and 1.55 AT THE MOST for complete stabilitly, but also requires a mid to high end heatsink.
Phenom II's are optimized for overclocking, so they don't REQUIRE that ACC is enabled to clock high. This is why all the PII chips and AM2+ motherboards have TDP ratings of 125-140w with stock voltage at 1.35 when the chip consumes closer to 60w. Most have no problem running stock speed at 1.2v, and can hit 3.5ghz - 3.7ghz without having to raise cpu voltage. It was really quite genuis to overshoot the TDP, they gave Intel the impression that they hadn't accomplished much in the way of improvements to either IPC or power consumption, while also requiring motherboard manufacturers to produce low price main stream boards that had would allow even people who never thought of overclocking to do nothing more then increase the multiplier without great potential for frying thier motherboard. A 4ghz clocked PII consumes between 100w and 115wl at 1.45v.
The main benifit i've seen for ACC is allowing for easy undervolting at stock speeds, and squeezing out higher clocks past 3.9ghz - 4.1. Could hit 4.1 without ACC at 1.4375 or so, but nothing beyond. After using downcore feature to run through each core individually with all 13 ACC settings and bumping voltage up in .0125 incriments, i was able to boot just shy of 4.6ghz at 1.5475, the weak link being the PWM's in 790GX board overheating, chip staying under 50c with a duOorb in 24c ambient.
I've had that issue only when AOD settings had reverted to novice mode, or preferances were set to load last settings logged when AOD starts after crash...or some such.Quote:

DISABLE THE IGP IN THE BIOS
it causes serious instability when voltage's and NB/HT speeds are increased just in how everything communicates, but also makes for looootsss more heat.
That is hot.Quote:

Great idea, very effective...unless you have a tower case....meaning the heatpipes will be horizontal to the cpu surface preventing that liquid from coming in contact with the cpu....because heat, and things like evaporating liquid vapors travel vertically....not to the right. I'm sure many people realize this, and think it to obvious to bother mentioning...which makes me think it the possible cause of all these toasty Denebs.
No wasn't been a problem for me it worked well on my 9850. I've got a volcano one in 64 bit.( it's hit 78C)Quote:

i know that there are better steppings out there that reach 3.7ghz on stock voltage. but that doesnīt help the fact that I CAN`T USE ACC. even if itīs not necessary, itīs a feature of my mainboard, so i would like to use it.
602 Bios works well with ACC.. ive been pushing 1.74v for CPU and 1.68 for NB with Stock Heatpipe on Mobo.. My 9950(first revision 140watt) is also watercooled. @ 3.55 24/7 and 3.6ghz max clock ghz..Waiting for 940 price drop then ill really put some clocks out with water.Quote:

Ive been gone a while and see things are moving fast with 940 already.
should be back home this weekend then i can read all the new post.
As for volts and ACC find the Cpu's Max first with out ACC and then raise ACC +2 and slightly lower the volts for CPU. if it works then try +4 and so on. But by all means make shure your Pc is up to date with Bios and that your Os is updated as well.
Get craking on that thing:D

As a result, ACC no longer provides the OC’ing benefits it did previously with 65-nm Phenom parts. In the words of AMD: “you can just as well leave ACC off for Phenom II OC testing. Since, the "go-fast" things we learned from ACC (and those CPU parameter adjustments) were factored into 45nm, the benefit unlocked previously by ACC in 65nm silicon is already being realized without having to use the ACC feature separately.” Over the Christmas holiday (before hearing this from AMD) we’d already attempted OC’ing our Phenom II CPU and sure enough, ACC provided no benefit when OC’ing the processor. We actually thought something was wrong with our 790GX motherboard until we heard back from AMD."

I can boot at 4.0ghz, but need 1.5v to do so. I need more to keep it running. If I lower NB it does much better. I might end up using the Gigabyte for this chip. It seems to like the Phenom II better. May be Asus will bring out a better bios that might change my mind.Quote:

Now try Adding some Volts to the NB on CPU and then raising then checking stability if by raising the NBvolts stabilizes things then clock some more.(920/940 use 1.35- 1.4v for NB to start) yes its safe to do . The 940 IMC is just like b3,, Actually its alot Better and uses less Volts for both CPU and NB.
This is a easy way to see if the Ram or IMC may be holding you back . By Raisng the NB volts it helps the IMC when the CPU goes up in clocks .In therory if your on the Edge of the CPU max this should make it stable. Most cases it does. Also Check the Temp of the CPU , this will hold you back too.
Note:
You should be able to Clock a little higher with a little More NBvolts compared to the First step (Raising CPUxmulti/htt while stock HT and NB is used)
As you do this balance act youll find that most of the time the NB likes a little voltage to keep things stable . Especiallywhen the CPU is going to the Moon. I always push the CPU first then Add NB volts to get more . Finally raising other things such as VDD and PCI0E Core Volts which is also Nbchipset on Mobo(1.32v)
Lots of people forget that the NB needs some extra volts too to keep IMC stable ..Just giving Vcore to CPU will not keep stuff stable ,Especially if going for that 4.0ghz and High NBmhz..
Also my old 9950 did not like high multi;s 17x was max,,but it loves High HTT for 3.55ghz/3.6ghz with 2600NB. I would treat 940 no different except for the HT which is actually Lower(3600 instead of 4000)
Is your HT too high above 3600 ?
This can give stabilty problems. If your going to be using insane High NB (2800mhz+) keep the HT close to stock for stability untill you know what is keeping you from getting more.
I wont have a 940BE for a little while yet , so i cant Post 940 results.
:up: But i can tweak the crap outa this Asus 79-T and i am waiting for a optimal bios to go above htt300 with me 9950.:D
As long as you have good cooling or your temps arnt a factor push that thing.
1.5volts on the CPU is like a snack for these things:rofl:
If anything you probally need more NBvolts / lower HT to 3600 / and set Core PCI-E to 1.32v.
hope something helps.
P.S if the NB is going above 2600mhz you will need to raise the NBcpuvolts for it Especially if you are going for 4.0ghz.

Hey, I kinda know the feeling. I had to go out of town for work and was not able to play with my chip. Watching everyone posting results etc. I was not aloud at first cause of NDA appearently, and then wasn't around to post when NDA lifted:p:. I got my 940 frre from work, so I kinda cheated.Quote:

itīs really funny that with phenomII u have to disable all the stuff that increased performance on phenomI.
cpu tweak is the most important. with cpu tweak enabled i canīt even get 3.4ghz stable. cpu prefetch is also disabled, as i donīt really know what itīs doing and it doesnīt help with performance.
both the ht and pcie-core volts are upped to 1.28V
cpu vdd is at 2.8V
4ghz is still a no go. maybe it has something to do with the sb750, as it always craps out when itīs trying to acces the hardisks (raid0 array).
but thatīs still a long way to that magic 4. first i got to get 3.8ghz stable which always gives me irql_not_less_or_equal or other ram related bluescreens after a few minutes of prime.
Just got my 940 today.
I love it I'm running everything stock bar the HTT is at 2000.
I have ACC off also.
I'll run some test asap.
Running windows 7 64-bit also.
Hey mad I just wanted to confirm how you did this.........Gotvoltage says to leave the ht and NB at stock then overclock using just the multi and stock voltage......once you hit your wall at stock voltage you raise the cpu nb voltage to see if it will stabalize......if it does you continue to move forward on the cpu speed until you need cpu voltage again lets say 1.4 or 1.45v till you hit the next wall then raise the cpu nb voltage again to see if it assists.Quote:

250x15=3750mhz @1.5v seems to be fine with the nb at 2.5ghz/1.4v
primed it for about 30mins, will try that again tomorrow.
my last try with 200x18.5 gave me errors in prime after 55mins.
i also tried going to 3.8ghz (254x15) on the cpu, but i either get a bsod or just a reboot at that frequency when i start prime.
going lower on the cpu multi and higher on htt doesnīt help.
i tried 267x14 to match 1066mhz on the 800 divider. but thatīs giving me a bsod shortly after starting prime.
Just a note for anyone who may be interested....
Since I installed my PhII 940 I've had one drive that kept clicking and failing during post (3 HD system). I actually thought the drive was failing and it was getting pretty annoying....
Yesterday I got the bright idea to bump the V's up on the southbridge to 1.22v's and the problem has completely gone away. :up:
Just thought I would mention it in case anyone else is having similar problems.
I'm only on one Hard drive and my sb volts are up to 1.34.Quote:

same here. post on 4ghz is no problem. i even get to the bootmanager where i can choose which os to load (vista or xp). just for fun i chose the vista memory stability test (when i hit tab in the bootmanager i can choose this utility) and checked for ram errors at 4ghz without any problems.Quote:

I can boot @ 4ghz into all windows accept vista. Windows 7 is most stable. I have been hoping for a new bios, or Asus going to abbandon this for the M4 board?
if this is the case and asus drops bios support for the m3a79-t, then someone should try flashing the m4a79 bios ;)Quote:

Given that the new boards aren't massively different to the current AM2+ boards then surely it's unlikely that Asus will drop support for them? Likely what works for the DDR2 AM3 boards will work for the DDR2 AM2+ boards.
Edit : When I say "what works" I mean Asus's optimisations to their BIOS, I don't mean that AM3 BIOS will work in AM2+.
Just got this board all hooked up and running the 9850 on it for now,,problem is tho in bios running 602 I have no controls in PCI express config, there is only the GFX Dual config....GFX2 Dual slot,,, peer to peer,,,slots power.......... There are NO Port numbers there in order to changed settings in ATI card, is there setting there for NB-SB Ports features....Running ATI CCC 8.12 right now there dosent even give me the option for Overdrive, cant Overclock the card, .......Bad mobo maybe..... has anyone had this problem before.....
Thanks
Try pressing F4 in PCI-E menuQuote:

hey,
so far i have this phenom 940 ii at 3808mhz with 1.552v cpu-z (bios 1.5125).
can anyone tell me why the board gives more voltage under load? or is this the builtin acc of the phenom ii?
this oc is intelburntest stable with 5 runs at maximum stress (full ram usage).
http://img262.imageshack.us/img262/7...omiixk3.th.jpg is in idle,
ambient temp is 28,3°C btw.
i don't want to go further until i'm sure how much voltage you think i can add to the cpu.
my load temps are 55°C according to coretemp during the intelburntest, and this is on water.
i read that the max temp is takes ist 62°C, is this true?
this is my first phenom (ii) and i don't want to kill it.
thank you!
installed XP with all the updates sp3 included, anyone know why when I start into windows it just freezes? happens all the time...bios 602 ide drive...Question, is there a problem with the Soundmax drivers on the disk..it seems not to work once I install those drivers....hmmmm
Remove all drivers and start again.Quote:

If this doesn't work either, do a clean format and start again with sp2 for start.Then if everything is ok put also sp3.
Thanks, I finally have it up and running with the 9850

Damn it seems i got a old bios, because phII doesn't post :/
damn you asus
itīs not the bios...Quote:

Make sure you have ACC disabled. This will prevent it from posting.Quote:

Just purchased my 940!
9850 on this board @3.5 in Vista 64

Peer preshure @ Xtreme gonna ,,wanna ,, needa buy urge is getting to me.
Pull ,, Ram and CPU and Battery . Then reinstall Battery,, CPU with one stick of Ram.Quote:

Once booted up and you can download Bios,, FLASH and USE the 602 Bios for ALL PHENOM for optimal performance and stability on ASUS M3A 79-T Dragon platform:yepp:.
Note:
Some ram may not default to JDEC ( reconized by Bios)
While using 302 bios It can under volt some types of ram( 1.5v instead of 1.8v ) cause a no boot.
Happens with some new and old Dominators and Kingston 1066mhz modules.Most *00mhz sticks should work fine.
1.22v - 1.28v is all that is needed.Quote:

In fact the SB @1.28v is actully good if running lots of hardware (drives and two+ or more Vidcards.)
P.S. i know ,, i coulda edited the above.
well, that didn't work..Quote:

thx to my little X2 4000+ for the flashing work :p:
Hey all Im all set up I got up to 3.5ghz stock voltage bench stable.....3.6ghz wouldnt get into windows so I upped the voltage to 1.4v (stock is 1.35v) and Im running benchies now. Im on vista 32 ultimate.
Bench just finished
19,475
sm2 7479
sm3 9899
cpu 4910
one thing......my multis only go to 20??
ASUS knows about that and the next BIOS should fix that 20x problem.Quote:

are they going to fix the no boot with ACC ?Quote:

Thats why it dosnt work on many mobos with ACC enabled,, Causes BSOD's or Noboot.
If i find a way to use it with 940/945 or if i hear of a( ASUS update CPU code) i will post it ASAP.
ATM ive seen and heard nadda about ACC and 940/945 being 100% workable.
For base Voltage i always run 2.8vdd (default is 2.5v) then i use whatever vcore which makes the Volts stock 1.3v (before i Oc). If i need more then i raise CPU/NB volts above stock setting. Thats how i get highest stable clocks with out ACC. Some chips will use less volts than others.
Note:
Phenom by far is one of the hardest platforms ive ever tweaked.
Just when you think your done theres a nother way to get More..painstakinly fun i must say.
Thanks for the tips on the SB man! I'm not sure if there is a sensor on it, I still haven't even figured out what TMPIN1 is in AOD but I'm assuming it's the mobo/NB.... Did you ever do the "finger" test on your SB @ 1.28v's?Quote:

The Asus 79-T is the first board I've had with this option, I've never quite figured it out either.... What software do you use to check for the 1.3Vcore using Vddc, CPU-Z? I've played with it a few times but have never seen any performance increases so I usually just leave it on auto.Quote:

If you enable ACC from AOD board boots ok. But when you enable it from biosQuote:

It only shows 0c
My cinebench score is only like 12,000 at 3.9ghz......Am I missing something?
http://i271.photobucket.com/albums/j...n771/speed.jpg
i wish i can get some of your overclocks , then again im only on AIR most of you guys are on Water
Titan7171: Cinebench really likes 64bit OS's, if your running 32 that may be why your scores seem low (I'm on XP64)....
Nice clocks BTW... :up:
Yep get that 32 bit garbage off there. vista or XP X64 and your scores will be a boat load higher.
Anyone have 8 gig in this board?
If so, how does it do? OC?
I remember reading in the manual way back when, that it will downclock to 800 from 1066 or whatever you have. Did I remember that correctly?
Yes its on page 2-11....For system stability when four DIMM'a are installed.all DIMM's run at DDR2-800 Mhz as the default settingQuote:

250htt on 800mhz divider
Here is all four DIMMs @ a 800 divider...

There is always a way.
Thanx for posting that Honda,, You reminded me that simply Showing a nice Sreenie is sometimes easier than explaining the whole shibang:D
Note:
Everest and AOD should show the VDD.
VDD is actually the Base Volts,, It mearly helps the Mobo not fluctuate as bad under load(Vdroop under load). The Higher the VDD the stronger(more Stable) the Base Volt will be during load provided im remebering that correctly:D
