I had trouble getting past 248 a couple of weeks ago, and if I'm not mistaken it was with 1303. Running well over that as we speak.

Killer NB speed! What voltages are you running Hondaguy?
Damn 3ghz NB I wish I could do that... What VNB and cooling? Water I assume?
Volts on NB are 1.4, for cooling is just air, in a Antec 900 case
I just flashed back to 1303 to test, and could boot up to 249, 250 on the other hand resulted in no boot. Flashed to 1202 for fun and booted at 268 (which I run 24/7 atm). So yea, there's something fishy with 1303 :)
Edit: Honda, how stable is that nb at 3ghz w. 1.4v?
Anyone got the 0803 bios saved somewhere..? , and also know how to flash to it easy.
Nothing wrong with 1303 guys except some slight ram issues......
To break the myth that 1303 won't let you passed 250 fsb..

can anybody tell me the correct vdrop and vdroop of this board while running prime?
803 is on the CD that came with mobo.......
I cant install older bios on mine, always comes up saying, bios older then board?:shrug:
installing bios thru EZ flash
1.4 is stable enough for sometesting, but for recoding Vid's it needs at least 1.45-1.475
Really? I can flash any bios i want, as long as it's for this board with EZ flash.

?best bios to Asus M4a79 deluxe
Nah this was the best bios for the 940BE in my opinion.
http://members.cox.net/bostonreefer4/airbench5.JPG
Ive got anothe question regarding vcore settings and which reading to believe....with bios 1303 setting mu vcore to say 1.25 in bios reads 1.285 in hardware monitor...if i check it in everest it says 1.31v and cpuz always reads what ever i have set in bios ...hardware monitor in bios always reads slightly higher at least in 1303...some of the other bios'es ive tryed have a larger gap between vcore setting in bios and what hardware monitor reads in bios...
I was wondering what voltage reading you guys are trusting to be the closest to what it is actually at....
has anyone actually pinned it out with a dvom using one of the latest bios....
Some of you guys have pinned out vcore with a dvom and does someone have an explanation as to where is the correct point is as to where you the point is where you take the reading from?
Page 1 I pinned it out ;) and the best point to get reading from is under the mobo........it's almost identical however......and not feasible while mounted in a case, or insulated for ln2.....not like I'm gonna remove backplate while benching ln2 to read vcore ;)
Came over this vmod if anyone is interested. Haven’t tried it myself so no guarantees :)

what are normally your guys temps in the southbridge "sb750"? Mine if 40ºC i think it's too hot. Has anyone got the same temps?
nb for 790 gx runs that hot. Its not normal for your sb to run that hot. Should be max low 30s.
I have checked the temps on my board with a infrared digital thermometer and my sb runs at 32c, nb at 34c and pwm at 33-36c depending on load...
Also I have very good cooling through my case..
Im using a 7750be right now and my cpu temps mirror what everest shows plus i put the infrared on it and the cpu temp is spot on what everest shows...the cpu temp is taken right off the heat spredder as the artic cooler 64 does not cover the spredder completely...even under load the temps go up some but nothing concerning..of course i dont o/clock like chew or wez...those dudes are mad scientists.....they are both very knowledgeable about this stuff and i so enjoy reading their posts...
there kinda like my idols...lol
I have to say chew is the one with magic fingers :yepp:
Regarding the nb/sb/pwn temps. I usually have similar values as you, and usually they stay in the low range. But have noticed that with high ref clock and a few more volts here and there the temps really sky rocket after a while under decent load. A few strategically placed fans usually takes care of that. But have been looking at a bit more permanent solution. AS adhesive was sold out everywhere so had to settle for some tape instead, but hopefully it will do the trick as well. I'll see how it goes as soon as the package arrives :)
my board makes a freaking damn noise when i turn my psu on without turning it on. do your's make the same? never payed attention till today maaybe it need to be rma'd
have you tryed a different power supply?
nop im using corsair tx 850. but when i was using the initial didn't heard a thing, but now since i updated to 1403 it squeels. have to change it to see what the hell it is!
Anyone noticed Vcore droop depending on CPU-NB voltage as well?
Lowering CPU-NB voltage made Vdroop a little worse for me.
So far my setup is running 3.6GHz Linpack stable with 1.4Vcore (bios) and 2.6GHz NB with 1.18V CPU-NB.
Testing done according to the "Tony-method".
Zeus
Lowering CPU-NB voltage made Vdroop yes;)
hi guys, i'm back to amd but i would like to know a few things. first of all how can i check my northbridge, southbridge temps? and one more thing if i check the voltage with asus pc probe and everest it reads vcore 1.47, if i check with Amd overdrive and cpu-z it reads 1.35. settings in auto bios 1403, but which one tell the truth?
use a temp probe on the NB and SB... there is not thermal diode that's displayed through software for those.
everest has always read correctly for me. in the Computer>Overclock section it will tell me the CPU VID and NB VID which are the voltage that i have those set to in BIOS. then in the Computer>Sensors section, down towards the bottom, it'll display the Vcore actual voltage... which is about .04 to .05v higher than the VID, but drops down to the VID settings when under 100% load. i believe that overdrive and cpu-z are reading just the VID, not the actual real-time voltage.
also, this board does some weird over voltage thing on the CPU core when the CPU-NB is set to "auto" - it over volts the CPU voltage by 0.1v. so set the CPU-NB voltage to whatever you need it to be (955 is 1.1v, 940 is 1.2v IIRC). 1.25v should be safe.
What eRazorzEDGE says is pretty much what i have found myself, everest sensors is the most thrustfull though hardwaremonitor in bios shows the voltages a little lower.
Guys, this Vdroop is driving me nuts, i'm running 3.6GHz with 1.4V set in bios, Everest reads out 1.45V idle and 1.42V load but once i start Prime95 blend it immidiatly reboots! :mad:
Can anyone tell me what's with the VDDA or whatever it's called, does this really help to set it to 2.8V and is it dangerous to run it that high?
I really hate to push more Vcore than neccesary due to that darn Vdroop!
I wish this board had Load Line Calibration.
I’m in the same situation, max prime blend stable is 3.6Ghz. Although I have only tried two previously untested 940’s on the board, but had the same result and behavior on both… Unfortunately I don’t have a spare am2+ board laying around anymore, so cant test them on another mb atm.
Setting the VDDA to 2.8v, or any other value for that matter, does close to nothing for me in terms of vdroop, so little that it might as well be fluctuations on my DMM. I find it a bit strange as some have reported that VDDA does indeed help with vdroop on this board... :shrug:
Also the amount of vdroop seems to vary from user to user.
For the record I’ve had it at 2.8v for 24/7 usage for months, and nothing have blown up so far. :rolleyes:
Is it possible for you to run higher vcore to overcome the vdroop, and maintain stability at higher core speeds? (on normal ambient air cooling?) I’ve only had minor success, but everything seems extremely dodgy when doing so, and I haven’t managed to gain 24/7 stability this way.
I've just been messing around with CPU VDDA but it did next to nothing for me except that when set 2.6V Prime blend crapped out earlier than normal.
I'm sure i can raise Vcore a tad or two to overcome Vdroop but that's rediculous, i'm sure this cpu could run 3.6GHz stable at 1.4-1.42V but i need to give it at least 1.48-1.5V to get it Prime95 blend stable. :mad:
I also played some with ACC but it did absolutely nothing.
I'm holding out for the Crosshair III, hoping it has good voltage regulation and LCC in bios even though it means i have to get a AM3 cpu and DDR3 as well.
Yah its not even vdroop that is the issue on this board to be honest, I can deal with droop but this board has droop up to x voltage setting and then over volts like crazy above X voltage setting causing it to be rather unreliable.
It's more of a voltage regulation issue than droop. I think they are trying to get it right but if they fix it on air then its screwed up on phase, DI, Ln2.....I think they should fix it for the air water guys and let people like me deal with the aggravation with the sub zero stuff since we are very few compared to air water guys.....would not be the first time I had to compensate when cold...
My latest gripe is the ram clocking is impaired with 955's........that should be a high priority fix atm.
Yeah, i noticed the same thing with overvolting, no matter what bios version.
Also the voltage reading in Windows is annoying, not one prog seems to be right.
Water cooling my cpu netted me some more mhz day to day stable! 3.45 is crunching stable at 20c load with 1.4v. Losing the air coolers dropped board temps nicely. Undervolting is still there but everything certainly clocks better! Is this board worth throwing water on the NB?
Here's my 7750 on M4A79 Water cooling also, just CPU loop
http://img20.imageshack.us/img20/932...33stockvol.png
Thanks gotvoltage! I was thinking of modding the NB/PWM sink to accept a waterblock is all. Wasnt sure if it would be worth the trouble. Board does seem rather cool now prolly just leave it alone. Its great to be WC again for sure! Cant wait for a Calisto chip to torture!!! :D Question: Will my NB clock be determined by CPU or the board? IE will a new phenom 2 possibly give me more NB clock?
Testing 3.565 @ 1.5v now Hondaguy! Ive never had it this far 0.o Winxp is sooo much better @ clocking then win7 was!
What bios are you running?
ACC enabled- All Core 0% here
3.5 here but rejected with Windows 7
http://valid.canardpc.com/show_oc.php?id=560031
1403! ACC auto, 1.5v wasnt enough, still testing! Cooling really helped this guy out! I was able to bench 3.525 @ 1.55v bios = 1.49 real on air, not sure where i max at with WC yet. 3480 @ 1.4v so far so good!
hondaguy after you said this, i tried validating with windows 7 and all is fine :up:

anyone test out the new 1602 bios?
yea the 1602 bios looks ok to me so far...seems stable for the limited time ive goofed around with it...there is another thread dealing with the new bios that has a few posts from people using it....dosent look like alot of big fixes yet...
at least my computer loads windows unlike the 1402 version did for me...
I'll give it a shot after class. I'm still having stability problems with 2.75ghz NB clock. Stress testing is fine but after about a week I'll get a random BSOD even with no load :(
Flash 1602
load old settings
save and exit
asks me to enter bios and restore settings, everything went back to auto
repeat load + save
same thing
load "default" and continue
windows wont boot
Gotta love ASUS!
Bios 1602 seems nice. :)
Remake the settings instead... The Bios has been changed so load setting can many times make that the board dont post(the settings have been saved in another bios). This is not only on the Asus board its on many boards. ALWAYS remake all settings and resave if you dont want get instabilty.
Maybe this is not the trouble you got but you never know :)
I'm at BIOS 1402 (1403?) right now and I can get 3.24Ghz OC with all Voltage settings on Auto.
I put bios 1602 in and I think it sucks. I couldn't even get 3.0 Ghz stable with a lowered NB speed and a voltage bump CPU&NB.
It also kept saying unleashed mode failed. With ACC on and with it off.
I put on bios default before flashing. Am I doing something wrong? Does ACC need to be on to use unleashed mode?
On another note I was pleasantly surprised, nay overjoyed, to see this one my new build for my wife
http://i510.photobucket.com/albums/s...n/surprise.jpg
Now I'm jealous as I want it in my ASUS
I dunno, i'm having good luck with 1602. Before with 1402 I was only able to get 3.5GHz with a 2.8GHz NB clock with 8gigs of ram. Now I got 3.6GHz with 2.8GHz NB and 8gigs of ram @ 1067MHz. Havent tried to see if i can push the cpu further or not.
Hi,
I was looking to get the Gigabyte UD4P board, or the UD4H, if I thought it was worth the extra
But, I think I may be able to get this board for a little over 100 pounds, and was wondering, how much better is it than the gigabyte boards?
Thanks
now this is a personal opinion, but i wouldnt take a gigbyte board if you gave me it, after 2years away from them, after a duff few boards i gave them another shot, when the 770/790 boards where released.
i went through 4 boards before giving up, again. after maybe 20 hours trying to sabilise the boards, at stock and just above stock levels, for me its allways a bios thing with giga, they just never sit right for me.
to be fair, apparently the giga boards ahve less vdroop / incorrect vcore than the asus boards, but latest bios releases seem to be fixing this, to a certain extent.
for me it was the asus, i now have 6 asus boards running here, all sweet as a nut :up:
Hmmm
I thought that the Giga 790 boards had decent BIOSes.
I was looking, as from what I had heard, they were stable, and guaranteed to unlock the 4th vcore a my 720
Can the Asus?
Thanks
this board does not have two different onboard raid controllers for the sata ports does it? I ask because I have my x25m hdd plugged into port 1 and have ahci enabled for this hard drive, but today I just got a sata dvd burner and plugged it into sata slot 5 and it is able to write at full speed, but when it is reading from the disc it goes painfully slow. And I know that most sata dvd burns have problems when ahci is enabled.
Promised someone I'd take a look see at the most recent bios on this board........goes back on bench tommorow. Been rather busy sorry for the delay.
Any new bios coming out for this mobo??? Could use one for this 550 chip
Hello chew,
was just wondering if you ever got around to testing bios 1602 on this board yet.....no rush dude jusk asking...
Yah sorry man I got tied up and it never made it to bench, will get to it after this weekend.
How max stable NB clock in this board with auto voltage ?
What the best hsf for mobo m4a79 without touching northbridge heatsink & tall memory heatspreader in the yellow slot ? How bout colermaster hyper z600, anyone used that's in m4a79 ?
I'd say that any tower design cooler that got a mounting system that let you mount it in any direction is your best bet.
A TRUE will cover the two closest ram slots, that i can say for sure. Take a look at today's top rated sinks, and then take a look at their mounting system and see which one is the most flexible, in terms of mounting direction.
The NB sink should not interfere with any of today's well known coolers, the RAM is the the only problem afaik.
Regarding the CM Z600, too me it looks like a bad choice, as it will most likely interfere with the RAM no matter the direction you mount it.
board is on the bench and running now guys.....Gonna toss a few sets of ram at it.....initial impressions is I lost a little cpu wise, gained a little ram wise..gonna try with NB up next.
http://chew.ln2cooling.com/qdig-file...20II/lrg_1.JPG
What vdimm are ure running for 600mhz and how is the Nbvolts treating da 955 ..
Just curiouse ,,
since you dont have the Nb cranked yet ,,
The 1200mhz + on the Ram already has the numbers up vs using 800mhz. Looks good.
Air? You just seeing what it likes to eat for a snack. 1.55v:D
Nah this board has droop chip likes 1.525 so compensating. 2.1 volts for ram....I just nailed a sick 1m for air :D so close to 15's its not funny, this chip has a weak NB though :(
Boards still flaky as far a cpu clocking goes though....inconsistent, one minute it fine next minute it wont even boot.......

http://chew.ln2cooling.com/qdig-file...20II/lrg_3.JPG
Ehh some more stuff....
This one is stable for the most part Wprime is still giving me a hard time....Usualy can not boot above 1.525 with this chip......It takes 1.5875 to do this on this board and boots......:shrug:
http://chew.ln2cooling.com/qdig-file...20II/lrg_7.JPG
Then I just played around a little bit......gonna toss the cellshocks in next as I had major isues with them on this board prior ( would not pull rated and sticks are not to blame )

OK now things are getting interesting.......I'm starting to actually like this board again.....If asus can get it more consistent...this board will be a sure contender again.....
My cellshocks actually work now.......rated volts.....rated timings...no tweaking ram settings.....
http://chew.ln2cooling.com/qdig-file...20II/lrg_8.JPG
overvolted .1 still easy mode.....rated timings no tweaking :shocked:

This wraps up cellshock testing.....
http://chew.ln2cooling.com/qdig-file...0II/lrg_10.JPG
Seems to be pretty solid for DDR2.
That Bios looks decent clock and Piwise.
Does it keep consistant Voltage settings when changing HTT up and Down.?
Ive seen some Bioses actually drop the cpuVCORE almost .1-2volt when a certain CPUx and HTTx is reached.
It would prevent booting some of the time but still boot Most of the time.
If or when it fails a boot (Check the Cpuvcore In Bios harware monitor). Ive run accross many ASUS bioses for ACC?even when not enabled,, drop volts after being set.
Usually happens when you raise HTT above stock and are above 1.45vcore.
Its like the htt and some volt ranges may conflict.:shrug:
Many ASUS mobos are also know for this,,
When you set CPU@ say 13x300 for 3900mhz and is sets 5000mhz :rofl:. Wouldnt mind if i had Ln2 when that happens.
Yah i'm familiar with the bugs this board has......problem is vcore is all over the place even with a damn good PSU so it makes for inconsitent benching....
Anyway My favorite sticks that cost $50 wanted to give the $200 gskills a run for there money :D
These win my bang for buck award......
Wayyyyyyy over rated specs for stability testing ;) they can do 1200 but I was just settling on a cpu speed that I know will pass all tests.....

Unreal clocks man thats all i can say,,those budget rams OMG:up:
What is max mhz you can run with that cpu on air in 3dmark2006?(all cores same mhz). And yes my board is undervolting much with air to, but its beter when the vcore goes up and using LN2 instead of air.
One more thing what is you +12v line in bios?.. mine is 11.5v but i dont trust it... i have tested with 3 Corsair PSU all make about 11.5-11.6v in bios hardware monitor.
4070 seems to be max it will 3d according to above testing.....I ran cpu test in all the test suites......if I can pass cpu test I'm golden.....mind you i'm not on my TRUE 120 atm. This is just my modded Xigamatek with my sanyo denki.
My 12V line reads higher....Using PC P@C however......tell you exact readout on a few....when I reboot.....
Board sux to use on LN2......the voltage regualtion is horrid......there is a voltage hole as well......at a certain point it jumps over a .050 volt range and starts overvolting up to .075v, droop doesn't bother me....as long as the voltage applied sticks......when it has a mind of its own that bothers me.....
Nothing special here just another set of ram I tossed in doing over rated stable.....
This should wrap this up as it seems I've run out of ram......
Yes gary I am a ddr II whore :ROTF: I still need to get myself a nice set of blades :p:

nice clock CPU, RAMs, NB
maybe with buspeed 225-228 and NB multi 13x? Or try diferent RAMs (1066MHz moduls) and busspeed 210-215 and NB mlutiplier 14x?:shrug:
chew,
I have a question for you...on the first set of benches your everest scores for read and write are like 1700 apart but on later benches they are very close...what settings do you tweak to get write higher and more equal to the read bench ....it seems to me that i used to have closer scores using the same hard drives that i have now...
mine are like 2000 apart an as i remember they used to be a few hundred apart...
i even reinstalled vista on a single raptor 36gig and the benches are close to the same as on my raid 0 setup....just kinda curious .....
maybe it was on my abit ax78 but i know they were closer....my son and i who is 15 have bench offs and i hate looseing to him as we both run the same type of rigs....lol
That would most likely be the NB speeds........In the first round of benches they were near default speeds.
Make sure the board did not drop it down to stock.........This board and the ddr III board both have a bug where when pushed hard they will drop your NB clock down to stock.......The fix is to drop the nb down a notch, reboot then bring it back up and reboot....
Really annoying bug, not as bad as the ddr III board though, that drops vcore settings to when it feels like it also.......
My +12 and +5v reads a bit low in bios (3.3v is fine), but stays over 12v and 5v if measured externally. This is on a 700w tagan.
I actually ordered another PSU yesterday, so will get back with results if the readout changes.
Edit: I'm such a liar, it is my +3.3 and +5v that reads a bit low, not +12.
Just got this board all going good so far
Can someone tell me is it cpu dependent on how far you can push the northbridge or is it to do with the motherboard i can not seem to get over 2800 mhz but i have seen some at 3000 mhz ?
CPU and motherboard dependant......you will not get 3000 stable on air....You might get it stable in a particular bench.......thats about all.
It was Hondaguy off here i saw who had his Northbridge at over 3000mhz mine will post at that speed then just crash
there's a new bios out by the way on the ftp v1702
ftp://ftp.asus.com.tw/pub/ASUS/mb/so.../M4A79_Deluxe/
2800 was my max prime stable on air, but its a no go now with the summer heat, it was on the edge before :)
BIOS 1702
1. Support new CPUs. Please refer to our website at: http://support.asus.com/cpusupport/cpusupport.aspx
2. Support H/W C1E function only for AM3 Athlon II X2 family4 CPUs.
Man they can't stop pumping out BIOSes for this thing...
Anyone ever have their CPU fan STOP? The other day I BSOD'd (at stock speeds) and rebooted to see FAN ERROR PRESS F1 or whatever it says. Got back into windows and by the time I opened hw monitor my CPU was still at 79C. Apparently the fan decided to stop spinning... I have it set as a DC fan in the BIOS control setup.
im sticking with 1602 for now, all i can see is new CPU support
shamon, wooo hooo, WHO'S BAD?
