Asus M3A79-T Deluxe

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?

**RiverRicer** · 01-11-2009, 12:19 PM

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.

**evilSuRGe** · 01-11-2009, 04:11 PM

All i do is set it to 1067 and 5-5-5-15 @2.1v in bios

**Chicken Patty** · 01-11-2009, 04:16 PM

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.

**evilSuRGe** · 01-11-2009, 04:26 PM

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

Check out ASUSes QVL (qualified vendor list): Memory Configurations for M3A79-T

Some modules allow you to populate all four DIMM slots, but others like the OCZ 1066 Reapers I purchased only allow two. I won't be going 8GB anytime soon, atleast at rated timings.

I'm think I'm running memory problems, but they OC above 1066mhz 1120mhz wouldn't got stable. even with votls at 2.3 but stable at 1,.98 at 1,100mhz

I hope they fix the 790FX ACC problems soon. I hope the problem IS fixable. The 790GX didn't have the free PCIe lanes necessary for my monster.

well my AOD just started reading wrong now ?

worked right like 10 minutes ago
AOD thinks I'm at 3.9ghz.
I'm working up to your 4.2ghz currently I'm at 3.5ghz.

yeah,AOD ACC might help us although I do have plans for an NV780A though.

My MSI DKA790GX did 1066 with 2 sticks of g-skill 800 and 2 sticks of a-data 800........and I was running 260+ bus speed.

**Titan7171** · 01-11-2009, 05:48 PM

Make sure you guys are using aod 1.4 not 1.5.......1.5 has alot of bugs

**Chicken Patty** · 01-11-2009, 05:55 PM

thanks for the input guys.

ya i think all the boards can do that (if htt goes that high) but i meant at the 1066 divider

**Daveburt714** · 01-11-2009, 06:41 PM

Does anyone else have AOD crash their system (just opening it) when CPU core is set higher than 1.45v's in bios?

Guess I'll look for that AOD.ini mod to allow 1.55v's in AOD even though it killed my MSI DKA790GX...

I'm pretty sure this Asus has a much beefier PWM section than the MSI did..

the PWM on the M3A79-T is great!

oh and AOD did that to me a lot, so I just stopped using it

**demonkevy666** · 01-11-2009, 06:55 PM

I'm at 3.75ghz at 1.55 volts. Idle is much lower then the last time I tried this with multiplier.
42C last time was like 50C...

If only they will overclock with less voltage, that would be awesome. How high in voltage have people taken the P II's already on water or air????

how cares about volts when you need the the MAX SPEED lol

I think I've found my problem I disable cpu tweak in the bios but AOD is coming up in red

wth....

Maybe its needed with the new chip

I noticed the C1E Support not working either with this chip

cpu tweak is another thing that doesn´t work properly.. i had to disable it too, to get 3.7ghz stable. when enabled i can´t even boot into windows at my settings.
asus´s bios guys really have alot of work to do.

CPU Tweak works here, with it on each CPU @ 800Mhz.. with 1.0 volts

**demonkevy666** · 01-11-2009, 07:24 PM

mine is stuck always on ??? (from AOD)
I've tried both form my bios
it's not working at all for me at all

I have had it up to 1.66 on water for at least an hour benching. Does not seem to mind it a bit.

that´s just CnQ.. i think it has nothing to do with cpu-tweak.
when i enable CnQ with my oc settings the lowest state is 900mhz/1.0V, but it´s not stable that way (because of the lacking cpu-tweak??). vantage crashed when i tried running it with CnQ enabled.
at stock settings i can enable everything except acc without any problems.

**Daveburt714** · 01-11-2009, 08:11 PM

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...
