Asus M3A79-T Deluxe

[Oliverda]

Oliverda, is that TRUE 120 cooler? Whats your temps?

Yes it is. My CPU's temps are around 53-55C at full load. 3.2GHz@1.35V

[oc_junkY]

i think i found the reason for the weird "downclocking" i´m experiencing when running prime95 for a few minutes.
it´s the mosfet/nb cooling...
even at 3.2ghz idling it´s getting so hot that u can´t really touch it.
just for fun i tried putting the stock amd coolerfan that came with my 9950 on the mosfet heatsink. that way i could pass 3dmark vantage runs at 3.4ghz without having those weird hiccups during the cpu-test (guess that was because of the "downclocking" when the mosfets or the nb exceeded a certain temp). that lil 90mm fan went up to 4900rpm during the benchmark so that heatpipe thing get´s really hot and i think i need to put it under water too.

Hey this is really hot, how do you read the MB temps?
I'm using asus probe2 and i' having around 31°C at full load with intelburntest using maximum ram.
What voltages have you set?
I'm using
HT voltage: 1.34
NB (core) voltage: 1.3

I've come a little further with my AMD system, i'm aiming for a 100% stable 24/7 overclock, because this system ist mainly my storage server with software raid and encryption.
here is a result with a uncommon CPU for this board

i use aod to read out the mb temps. but i also have a thermal sensor of my zalman zm-mfc2 attached to the fins of the heatpipe cooler. that sensor reads 65°C under full load. that´s only the cooler fins, so maybe the whole mosfet and nb are getting a little hotter.
the voltages for ht and nbcore are at stock. cpu is at 1.4v+2%acc at 3.2ghz.

i can easily put my fingers on every peace of copper (mosfet,nb,sb) on that mainboard, and it's rather cool.
there are 2 possibilities:
1. your phenom is stressing the mosfets/northbridge much more than my x2 5050e or
2. your board is not ok

have you got annother cpu which you test the board with?
and btw, whar are your ambient temps and which case are you using?
mine are about 20-22°C and the board is in a sharkoon rebel 12 with a 25cm fan blowing at it.

Hi guys, I've decided this is the board for me, but can someone please explain the 1066 memory thing?
I've read that the Phenom can only handle 1066 memory in 1 stick per channel? So does that mean we have to run our mem in single channel mode? Or drop to 800 in dual channel?
Sorry if this is a stupid question, or has already been discussed, I'm just a little confused?
What benefit does dual channel give? And would 1066 single channel be better than 800 dual channel?

[Chicken Patty]

Yes it is. My CPU's temps are around 53-55C at full load. 3.2GHz@1.35V

You sure the heatsink is seated right? Maybe the thermal compound not applied correctly? When I got the new board that I tried it without taking off the AM2 retention bracket I tried it on air and with my 9950 @ 3.2 GHz @ 1.4v I saw about 55ºc full load with the factory Heatsink.


Couple of questions

1- What is more or less your ambient temp?
2- what are you using to monitor temps?
3- What were your load temps before the TRUE?

phenom can run two 1066mhz it's 2gbs sticks put more stress on the IMC. 9 I haven't seen many running 8gbs yet.

in ganged mode it runs in one 128bit dual channel and unganged it runs two 64 bit channels.

there difference is in mutli-thread programs and single threaded programs

[Oliverda]

in summer not stable

Yeah, but it's still much better than you. As we see you are not stable even in the winter at all.

I'm sure and I use AC MX-2 tc. The ambeint is around 25C. I use Everest for monitorting. It can show the core temp.

I can't remember my load temps before the TRUE because that was more than a year ago with different board and CPU.

Overall I'm pleased with the temps because I have a relative slow fan on the heatsink.

Thanks. I dont know, my ambient temps are around the same, I used Core temp for readings, but core temp and everest are only within a few degrees of each other. Regardless i'm sure temps went down so its an improvement anyways

you can run dual 128 in both ganged and unganged On this bored. I couldn't on the K9A2 Plat board before I sold it tho. But all my other boards allow me to. As long as the DIMMs are in the right slots.

that doesnt sound toooo bad, but id have to agree that they sound a little high for the V's considering the true copper is supposed to be best air cooler... at 1.36v mine sits around 47-48c and if the room is warm 50-51c max. also using mx2

Thats what I thought, but not every rig, not every configuration is the same. Maybe although his are still a bit higher than some of the other users, maybe he still saw a good decrease in temps. If thats the case, then I guess its all ok.

well.. i hope that my phenom is stressing the mosfets a little more than ur x2.. at least it´s a 140watter.
i don´t have another cpu to test with. why should i test? it´s working properly if i don´t stress it too much, 3.4ghz@1.6v is really stressing it.
ambient temp is around 23-25°C and my case is a chieftech mesh big tower with a 3x120mm radiator in the top and one 120mm fan at the back under the powersupply. if i had a 250mm fan blowing at my board i bet it wouldn´t get hot. but i´m on water so i don´t have a really good airflow over the board.

test it with either PRime 95, or wprime, wprime is a multithreaded benchmark that uses all cores @ 100%, works very well but doesnt kill PWM's like prime does.

c'mon guys,
I want to see some phenom II teasers with the M3A79-T

[N19h7m4r3]

I just ordered this Mobo for a Phenom II.
Hope it handles good, and I hope they don't bring out new AM2+ boards

Hey, thanks.
I was gonna get a Phenom 9950, but I've now decided to wait for the Phenom II, so I've bought a cheap Athlon X2 4000+ from eBay, just to get up and running. That way I can make sure the BIOS is flashed to the latest version for Phenom II.
Still havn't bought any RAM though......suggestions?

I was thinking about this stuf

Not expensive either.

Has any of you guys had an issue with the board not posting and crash recovery not working?
Everytime I raise HT above 2000 the board will not post and i have to clear cmos.
IT's pissing me off that i cant overclock the HT without it not posting and i have to take out my 3870X2 everytime to reset cmos.

Had my HT up in "sync" with my NB for a while (around 2400-2450 MHz) with no problem other than heat. Lowered down to 2000 to shave off a couple of degrees, while keeping NB at 2400+. It should work! (I imagine(?) that 2400/2400 "felt" smoother than 2000/2400, but I am probably wrong...)

What bios do you use? Did you load default setting after flashing (if you have flashed)? Do you overclock in bios or via AOD?

just out of curiousity what BIOS are you using?

I had that issue with the 0504 BIOS, I couldn't raise my FSB or it wouldn't post. Wierd, but it was the BIOS. I returned to the 0403 BIOS after that and rig ran perfectly.
