Asus M3A79-T Deluxe

[RASTAVIPER]

The oddities I've been having are that whenever I try to amke any changes to voltages in the BIOS for CPU-NB Voltage, NB Voltage, HT Voltage, CPU VDDA etc, then the system fails to POST needing a CLR CMOS via the jumper, which is a real pain as I have to remove one of the 4850's each time to get at the jumper cap, if I keep doing this I'm usre I'll end up wearing off the gold on the X-Fire connector tabs, with all the putting on and taking off of the Crossfire Bridges...

Well, I don't know if you had checked the manual, but sometimes when your system doesn't post, you can try to restart it and then during boot press DEL, until the system starts normally.Then you can insert the BIOS and change the faulty settings.
Unfortunately, this doesn't work always and sometimes only by clearing cmos by jumper, solves the problem..

you can shut down the system, and then pres INS on keyboard, and fire up the system again while holding the INS, after first beep, start pressing DEL to enter the BIOS!

I was reffering to the "CLEAR RTC RAM" function, where after changing the jumper you must press DEL.

Hi guys...

Well I've been a bit busy for a while had a few personal things to take care of...

The mobo arrived as promised by Scan, and I even got it all installed into the case the same day. But didn't have time to try to install the OS until today.

Well I fianlly got the OS installed this afternoon.

I've been running into a couple of little oddities with this board compared to the M3A32-MVP.

I've flashed to the latest BIOS 0602, and have installed Vista and all updates, etc...

My temps are great, I'm just testing high voltage temps at the moment and have set VCore to 1.475v and CPU @ 3.2Ghz,

Idle is showing 36C on the CPU (IHS) with Cores showing 37C (C'n'Q disabled of course)
Load is 44C CPU (IHS) and 46C on the Cores.





Anyway, I'm in the process of trying to figure it out, by gradually making cahnges one by one as a proess of elimination to try and rule out the cause of this littel problem.....



I'm pretty sure it may have something to do with either the HT voltage, or the CPU VDDA Voltage, settings that is causing it to fail to POST.

I currently am at

CPU @ 3.2Ghz and 1.475V
NB @ 2.4Ghz and (Stock Volts)
HT@ 2.0Ghz (Stock Volts)
RAM @ DDR2-1066 (2.1v)


******ACC @ Auto*******

Pretty much everything else is on Auto settings at the moment, CPU TWeak,

******Auto Express*******, etc..etc.

I'm kind of hoping to get this little glitch ironed out soon, so that I can see what's what....

Im using the 602bios and the 302 is decent but lacks Agesa updates ..The 504 is buggy as bleeep.

First,,

you need to Disable ******two Items*******


Next,,

nice chip, temps are good .
little shy of volts for the NB to function @2400.

This works

CPUvcore 1.512v
NBvcore 1.512v
this should give you a CPU/NBVID value close to 1.42v ..It will work for 3.3-3.35ghz and will be about the same temps you are at now with VDD @2.8v.

The ASUS 79-T will use more Vcore Vs your OLD Mobo MSI..Since the VIDs auto adjust with higher Vcore with SB750.using ACC mearly adds more or less volts to what you intially have set in CPUvoltage and NBvoltage. Using +/- or AUTO ACC.. I disable this ACCfeature after finding it dosnt always auto adjust and will cause a (noboot) if it auto adjust with too much or not enuff volts.

Set the New VDD value and others i have listed below.



Set VDD to 2.8v

set HT to 2.8v

Set Core/pcie to 2.8v

Southbridge AUTO

Keep me posted.

Note: this should give you stability. Even Raising the CPUvcore to 1.6v and Nbvcore to 1.52v on this mobo is no problem ,, your temps are just fine..

I could post Volts or even Screens of what to set( Ive tested them all) while not using ACC for up to 3.5ghz/2600nb if ya like.

Example,,

This is with 1.6v on both NB/CPU

screen is With out ACC...
remember ACC only adds or subtracts volts from what you origanaly set for Vcores.

Which slots do you use for the RAM sticks? I have 2x1GB SuperTalent and I use them in the first two slots next beside the CPU (yellow and black).

you have to match them colorwise.

Yellow with yellow Black with black.

Use the ones closest to the CPU that are the same color, so you should have an empty slot in between.

Yeah USE YELLOW or youll have Oc problems garenteed when using TWO STICKS...Ive tested that myself with Corsair Patriot Kingston Buffalo and OCZ

You know whats funny, I knew that you had to color match them, but I just happened to see in the manual today that if you dont use the yellows, you'll have problems overclocking. Coincidence heh haha.

Thank you for the replies!

Could someone of you please post a screenshot about the BIOS RAM timing section? Thanks in advance!

I have never changed the voltage to HT and Core/pcie.
I sure will try to increase it just for testing.
Is there any chance that any subsystem react badly to these voltages??
I am stable at 3.450 and I have max post at 3.720...

Ive spent lots time reviewing and checking spec for running SB/600 and SB/750 HT // CorePCIe // Southbridge volts..1.28volts is @ medium volt range for HT and COREPCI-e ,, 1.28v HT Can easily push 290+ with Phenon and Crossfire..

Southbridge id only adjust if running more than two cards ,, especially if thier overclocked..

The subsystem is 100% even while using stock Heatpipe..Temps are identicle to Auto setting.

OK well I think that my PSU efficiency may be to blame here, I noticed that whenever I start running a 3DM06 run that the PSU fan starts spinning up faster and faster during the graphics tests, then will slow down during the CPU tests, then speed up again, which to my mind is a clear sign that its having to work harder to provide enough juice when the x-fired 4850's are running at max use....

So I'm wondering if when I try to up the VCore etc, and then the cards try to start up whether the PSU is just insufficient to meet the needs..

My PSU is a 2 year old THermaltake Toughpower 750W.

I'm owndering now whether to step up to a 1Kw PSU or just wait it out until the PhenII's come out, which won't be that far off now really...!!!

I probably won't be adding any more gfx cards for the time being, though had thought about getting another 4850 for a HTPC I have, and might have stuck it in this PC to try out Tri-CF, but given the whole PSU thing I'm not sure it would be wise now...!!!

[XRogerX]

Hey kAZgIRL Glad to see your still alive, im on a 650 watt right now and im waiting for my 1kw to come in but its not going to get here untill the next month cause of the holidays , the PSU i have right now is running hot and i cant clock my cards like i want to so i think im having issues also the fan isnt speeding up or anything in this here so im getting a new one and im glad your bk

Hey Kaz,, The PSU is just Cycling the Fan for Heatload when the CPU and GPU's are pushing it..


As for the load and PSU fan cycle the PSU should run the Fan higher Under Load..If your not crashing ,,your fine for now.


When there is no load the PSU fan should be Idle (less heat) When there is heavy load it Should Raise to cool PSU)
Run 3mark06 with Rivatuner open in the back ground to check if the GPU's are downclocking in CPU test..this will be less load and the PSU should then be able to use less fan(less heat from load).

If that is the case then i would not worry about the PSU losing volts or trying to up the volts...Its doing its normal cooling cycle.

Although a PSU of 850watts or higher is what id use for Tripple Xfire...I dont think your PSU is a problem ATM untill you use tree cards.

I only use a 650watter for runing 3870x2 @ 920/2200 with my CPU @ 3.5ghz with 1.65volts for CPU/NB...I know i pull Max load and i allways run My GPU fan @ 100% in benches ,,GPU fan stays @ 100% on every test...I can hear my PSU cycle the Fan up to cool its load...This is normal function of most PSU's..Yes your probally pushing it close to max load.

Also for a little more GPU coolness,,
look into what your GPU's are doing during 3Dmark06 and youll see that they may be cycling down per ATIpowerplay..If you dont have a Oc set for them or dont Use 100%fan .Powerplay is know/ can cycle the clocks Up/down it all test more so losing points in Mark test..I always set fans to 100% or disconnect the Blue fan wire(unpin only Blue wire) on each card to enable 100% fan . Sometimes Rivatuner may not do it for both cards.


I dont think your PSU is a problem yet

Once you try 3 way crossfire you never be able to go back (2 way crossfire runs to dran slow) FYI .heheeh!

[kazgirl]

Hey guiys thanks for the replies...

Well the system doesn't crash at my current settings..!!

What I meant was that the PSU may be why I can't seem to OC the CPU any higher, i.e. if the PSU is already at its threshold, then upping the voltage and clocks on the CPU may be increasing the strain.

I've managed to boot into Windows at 3.3Ghz and even at 3.4Ghz but as soon as I try to run anything intensive, especially 3DM06/3DMVantage, then it will crash almost straight away.

Thats why, when I noticed the PSU fan increasing speed during the 3D tests in 3DM06, I started wondering about my PSU maybe being the limiting factor.

The Riva Tuner idea to monitor the CPU/GPU use thing, thanks for the idea, but I have Everest Ultimate setup with the built in Logitech LCD display enabled, as I have the Logitech Z-10 speakers with LCD display and I have all my system temps, and CPU/RAM/GPU utilisation showing on it, so whenever I run a full screen app, I can see the statistics on the speaker LCD display....

Yes, I have noticed that the GPU utilisation cycles in between tests, so say when the first 3D test load the Proxycon one, that the GPU use go's up accordingly, then when the test finishes and 3DM06 does the system scan before the Firefly Forest test, the GPU use drops to idle again, then cycles back up when the FF test starts again, when the CPU tests start the GPU use is zero, and the CPU use is maxed, (well not maxed but between 95-98% per core etc)

So anyway with all this and noticing the PSU fan thing always speeding up when the gfx cards are in use, I just figured that maybe if its doing that at my current settings, then maybe it was a sign that the PSU was being loaded (possibly to the max) with its current loading, and that maybe thats why I can't seem to OC higher, as the PSU just can't push past this and maintain stability...

Does all this make sense... LOL..!!!

Anyway I'm in 2 minds what to do, I really need to get some new HDD's for storage, I also want to save ready for the PhenII (think of the plural of Genie for the pronunciation..LOL... so Phenii or Feen-I ....if you like.... ) I also want now to maybe get a better PSU.... but Xmas is coming which is going to cost a pretty penny as well....!!!

I hate this time of year.... there always seems to be things I want to get, but Xmas is always around the corner as well..... Last year it was Phenom B2, when I got the 9500, then just after Xmas was the AM2+ mobos, then not long after Phenom B3's, then the 4800 Series, then the SB750 AM2+, (which took long enough) and now its coming up to PhenII.... you got love the ongoing upgrade path....

Oh to be uber rich...

I do have one Question for ya Kaz is you AMD AOD show both GPU's?

[charged3800z24]

well, to further my addiction, I bought this board and another 9950, 125'er. What bios should I use .. I read mixed reviews for many versions....

[gOtVoltage]

602 ...ATM ASUS 79-Tdeluxe

Heavily overclocked i can use my SATA and USB's just fine..No audio pops while using onboard HDsound..

Even my Audigy4 works fine when i run with the GTX260 or 3870x2..

Just take the time to tweak Voltages and Ram..its by far the most stable ..

Most problems arise when people run ACC too+ high or _low or even use Auto instead of manual tuning..Auto can easily undervolt/Overvolt cpu This goes for all bioses ATM.Matter of fact i use a combination of High VDD with ACC+4 and 1.62volts for 3520mhz with 1175mhz ram..

I like this Bios very much.

compared @ 3.5ghz VID's needed to be 1.55 +vdd 2.8 ,,

292x12,,,,
302= 292htt no ACC/auto+2 would reboot
403=292htt No ACC/auto+2 would reboot
504=280htt was real buggy would shut down and have to ClearCmos using ACC.

602=296+ can use ACC+4 with less VID(1.52) while using VDD@2.8@3520
I have not had to Clear CMOS even after +8ACC and FORCING a bunch of reboots testing.Thats a big gain in my book .Means ACC is actually working somewhat.

Ram will vary but i try to use the Highest Freqency i can ,,which is 1220mhz @ below 3.4mhz... 1175mhz for 3520mhz..

Thats my 2cents.

[charged3800z24]

thanks for the info GotVoltage... The board and CPU arive today..I am working today but am off untill monday...so I should have some good try's at this setup..

[leoy]

Guys is anyone noticing squealing sounds from his setup.When i open cpu tweak the sound goes away, disable , noise back. It's very annoying beacause it transfers through my studio monitors.

[kazgirl]

I do have one Question for ya Kaz is you AMD AOD show both GPU's?

Hiya..

Yes AOD shows both GPU's in Diagram and detailed System Info tabs:

Diagram:



Detailed:



But notice that it doesn't display the Clocks for them though, probably as they've been OC'd via ATI Overdrive...!!!

[XRogerX]

Wow thats messed up cause it only see one GPU , but in status montior part it doesnt show no Gpu

[gOtVoltage]

It could be your PSU underload...

Mine dosnt sqeal and i run the whole system maxed with 11-120fans and two pumps and two Sata optical drives and 1 SataHD and 1 usb Printer @3.5ghz,,with a new GTX260/216 .

Im Also only using a 650watt PSU ATm and seems pretty good...

Your on a 620watt..It could be PSU being noisy or even the GPU4850 making a little noise....

I get no extra sounds though any devices..My sound is crisp and Clean ..I use a Audigy4 with Gaming headphones along with a 5.1 surround set up when i watch DVD's and burn disks.

Also in the BIOS i use CPU tweak enabled.. I dont overclock with AOD except to look at settings.

im using 2.8vdd and +4ACC ATM @ 3.514mhz 2400NB @ 1.65v cpu / 1.6v nb which gives me 1.55vid cpu and 1.46vid nb while using ACC.

I have not heard any sqealing or audio noise through my system with any Overclock i have done on the ASUS 79-T to date.
