Asus M3A79-T Deluxe

[ecat]

SpeedFan 4.38 fan control working with bios 0803.

Maybe a re-install helped but most likely the problem was between keyboard and chair I'm not a great fan (no pun intended) of target temperature control, it may be ideal for air-conditioned rooms but not so good for my situation. Still, it does what it says on the can. Now if Asus would give me a little more control over Q-Fan, a'la dfi 939 ultra max speed at T, I'd be a happy man, for an hour

Just a quick question...

Has anyone had any luck unlocking the 4th core of a 720be using this board?

And did you have to use the beta bios from the other thread?

[ecat]

4th core ? Sure, under 703 at least, my 4th is borked so I've not tried it with the later bios.

[Daveburt714]

Thanks ecat..

The 4th core on mine works, I'll try it on the Asus board.

Just so folks know... Bios vers. 803 will unlock the 4th core on a 720 (provided you got lucky on the chip). Just make sure you set ACC to "per core" and set one of them to something other than zero...

I just set them all to +2 I wonder how much it matters....

So you like the chip eh? We should do a OC session sometime, I didn't realize how close you were.

Hey guys, I'm in the process of RMA'ing my Maximus Formula (sound DOA, NIC's died just now) and if they let me I wanted the M3A79-T Deluxe in return. So I'll retire my q6600, get a 955BE to go with this board and try to run my 8GB of G.Skill 8000's. I had a different board in mind first, but this here would let me reuse my RAM.

Is the whole thing a god idea? Thoughts?

I cant get mine to unlock with 803 Bios ..




Do you have to make shure Three of the four cores read 0 and only one Core is bumped up or down?

Its odd 803 wont enable it for some reason on my Mobo.

My 720 will do 3700mhz on X4cores with Mod bios though ?

Did you do a CMOS clear before Enabling the Fouth core with 0803 Bios.


Ill keep trying with 803,, for some reason it will only work with MOD 0030 Bios on mineATM

I run a 940 and a 720 on this board and it is a nice combo. Board is solid and I got my 940 to 4.2ghz stock water kit. 3.9ghz 100% stable I was am running 4gig tho, haven't tried 8. I think it is a good idea, the Phenom II x4 955 BE is a better chip then the q6600. No matter how you slice it.

I did a power off of PSU, cleared BIOS, powered back on, set ACC to +2 Per core.

Ok i just tested My 720 and Mobo with 0030 MOD BIos... I have to set NBvolts to Auto for 1.20vid and i use 1.568v for CPU to keep it happy @ 3700mhz with 2150+nb....

Maybe i had my volts to high for the 0803 Bios to enable it @ 3900mhz.

Gonna reflash again and power off PSU CLEAR CMOS and see what happens.

This is where im @ ATM

[Halk]

What's the default for the BIOS setting "Processor-NB Voltage"?

That's what I was hoping for, a solid board. And maybe running 4GHz while folding.
But let's see what the store says first, thanks man.

Would you think the NB/VRM section need water/extra fans (also, is water on the SB needed? I would slap on a small Enzotech HS..)? Sorry the only thing I ever fiddled with on AMD was with my Turion MT-34 on an MSI board, and that I only undervolted. So in short I dunno what needs extra cooling (and seeing that VRMs are rated 125°C and upwards I wonder if it's needed at all).

[gOtVoltage]

Default Bios NB @ 1.20v with Mod Bios and 803 Bios.

My Chip refuses to run 4xcores on 803.

It does like The Mod Bios for 3700mhz but is Slower than what i can tweak with X3cores.

I finally am able to Get 1200mhz ram stable with 2700Nb @3900mhz X3cores.



It takes a lot more .10 volts more for 1.648v@3900 vs 3700@1.55v and extra core.

Mobo wise Im using the STOCK Heatpipe and Only CPU is watercooled. This Mobo is a solid performer for the Volts ive hammered through it over the Last Year 24/7 Above 1.6v......

[Daveburt714]

gOtVoltage: I didn't do anythng special to get it to work on 803.

I tried these ACC settings with no luck:
Auto, All Cores 0, All Cores +2 and Per Core All 0.

When I set it to Per Core 0,0,0,+2 it worked! I haven't played with it a whole lot (been focusing more on the OC), but I have tried a couple other settings and it seems like anything with 3 0's and 1 @ +/- 2 at least booted.

I flashed the bios with a 940 installed. I doubt it would make a difference, but it may have written some low level code that makes it work on the 720.

I am not sure how "needed" it is, but I have always placed a fan over top to keep them cool. I never saw the need to water cool them yet.

Thanks, so the board is stable and there's no real need of highend cooling. Now I only need the ok from the shop.

But after asking that I realize that you could have rightly pointed me to the forum search, this exact topic of necessary cooling of AMD boards is already covered, for example here. It always annoys me when people are asking questions that have been answered couple of times before and now I'm doing it myself. Sheesh.

I don't mind if someone ask a question. I don't always know or remember what was covered. I then would have to search and find it to then tell you to find it LOL. I just hope my info was helpful.

I managed to reduce the Vcore from "AUTO" (1.456V ) to 1.38~1.39V @ 3.6GHz
Lower than 1.38 the board won't boot and I have to clear CMOS, reload the settings again every boot

How bad is voltage droop with this board btw?

[Daveburt714]

My Chip refuses to run 4xcores on 803.

Well gOtVoltage , after a little more time testing with the 4th core enabled you were right about 803.... It does ok with mild stress and the short benches I use to rough things in, but when I really push the system I can't get it stable even when I lower the 4th core down to 13x using AOD... I'm sure you jinxed me. Ya happy now, Bastage...

This chip doesn't seem to like high v's either, I could only get an extra 100Mhz on the Asus compared to the Biostar, and the Biostar seemed to run the 4th core stable (more testing required).

Guess I'll be swapping parts agian this weekend...

charged3800z24: Looks like I should have bought your spare 720 man...

Actually the M3A79-T overvolts a little.

Thanks.. Will post back my findings in a bit.

Ok while im downloading the 64bit Win7 RC i decided to Load the 902 Bios.

I can reach 4014mhz with less volts now.

Seems theres a few Bios tweaks added for more stability.

Temps are the Same as 803..

.AHCI work like a treat.

The 902 may be the one for me to get 4100/4200mhz stable.

As for x4cores on a720...it was a no go for me. Again to double check i reinstalled 0030Mod and did 3700mhz X4cores. Then unistalled and flashed 902.

It would not give me that extra core. Oh well.

902 As with the 803 bios . When i set ACC -2 on CORE zero it will default Volts to 1.408v That is the only bug ive found so far. CnQ works same as 803 and may be even more stable.

I can use Auto ACC/Per core/Allcores just fine with the 720 (+4allcores)..Its only when Core0 (-2 is enabled )where it lowerers the volts.

Ram timing is the Same and i can go Above 600mhz with 800/1066mode no problem. You just need to loosen things up to do it with some finicy rams.




This is a good Overclocking Bios. It used to take 1.65v to do 4ghz. Im liken it a lot actually.

gOtVoltage: I'm just curious man, when you say 4 cores with the 720 is a no go, do you mean it won't even post or it's just not stable?

I'm asking about release bios btw, not the mod version...

+++++ 902 .

I can use any ACC setting and it will not unlock.

ACC works just like its suppose to When adding -/+ volts.

+++++ 902 wont unlock this 720chip at all. I know the 803 tries to and sometime will enable it ,but the 803 was buggy and no where near stable. 902 nothing happens period.


I can unlock and run chip @3700...Using MODbios only. Most stable.but you can only use 14x multi and have to raise HTT to clock.

Just can not on 803 // 902. Its a Bios Firmware thing . The MOD bios uses a Older Firmware before ASUS updated it.

I was really hoping the 902 would of had a hidden ACC Firmware feature like the new Giga Bioses . So you could use old/to unlock or new/to not unlock firmware for the 720 tweak. Oh well.
