M3A overclocking

[thigobr]

Yes. People said that there is no problem with this behavior.
I saw a Abit P965 that do this "reset". And other Asus do.

[zhadoom]

I'm using 0805 firmware. This behavior of power-off -> 1s delay ->power-on only happens after a save in bios ( 1st reboot ). Otherwise the boot is normal.

[SocketMan]

It does that to ensure a "cold boot" that is the only "explanation" I can think of.
I must say this board has gotten better and better since the earlier days.
If it had more PCIe slots and full AOD support I could almost get another one

[thigobr]

Lack of full AOD support is the big drawback of this board...

By the way I am talking with the developer of SetFSB for support ICS 9LPRS477BKL(clock generator) but I need the datasheet of it. I can't find in IDT website... If someone know where can I find it, tell me.

[justapost]

PM me an email i'll send it to you. (9lprs477c, specs work on M3A,DFI790FX and GBT780G)

EDIT: Saw you already did, so I mailed the specs to you.

All boards i saw with that chip use the m/n method to define the ref HT. The divider part differs between boards and sometimes with different ref HT's.

The formular i figured out is.

ref HT = m/(n*d) * f

For the CPU PLL the factor f is 50 on the GBT board. For the other clocks this factor is 14.31818. Normaly the factor should be 100 according to the specs. that's abit odd.

The second divider d(CPUDivRatio) must be looked up from a table. (see Byte20).

SetFSB is a great "little" (size wise) program,would be great to use it on a desktop,
and not just a laptop at work

[SocketMan]

Got the new AOD installed and it's showing that both sticks are in chanel "A".
They're in the first 2 (from the cpu) slots:
Other combinations get the AOD to hang when you start it, getting better but
still work to do for Asus

So does setfsb work on the M3A?

BTW Could you post a link for the clock gen data sheet?

EDIT::
So I emaild the setfsb dev and he replayed like an as
He says:
There is not your greeting in this E-mail.
There is not your handle in this E-mail.
I think that you do not know politeness.
I do not support you. Please resign oneself it.

So I asked he for a link to the source.

[thigobr]

SetFSB isn't working in M3A yet... I already sent the datasheet to him and now I am waiting.

I was looking trough this tread and used the search, but can't find any hits.

Is there a Vcore and perhaps Vddr mod for this board ?

CRFX posted a pic for a vcore and nbcore mod here

[arthur92710]

What does the mod do?

Increases the voltage gor the non BE Phenoms if I remember correctly

[arthur92710]

Oh, cool thanks for the info!

Does anyone use speedfan?
I do, and temp1 gets hot, like 50C, while core stays cool at like 24C.
I have felt around the mobo, and the cpu HS is cool but the small black one that says ASUS get warm.
So is temp1 for the black HS? Whats under it and why does it get so hot?
I have changed the grease for the big HS above the video card to AS5 but when I tried to do it for the black one I could not get the clips off.
I think I would be able to get better oc's if it was cooler.
What do you think?

[Piotke]

Increases the voltage gor the non BE Phenoms if I remember correctly

Any confirmation if this works for regular AM2 cpu's as well ? I can only give about 1.5 volt to my sempron

[|SiLA|]

any of you had the problem ionstalling the audio drivers?
can't install them

tried several times also installing first sp3...drivers from cd and online asus..can't get it to work

In the bios change the audio setting form HD to the other one. Its like AC97 or something, cant remember atm and not at the pc right now.

CRFX had success with an 9500 so it should also work with an k8 cpu. No need to shade the nb resistor here. With the 9500 phenoms the bios only allowed 1.25V.

This option is for change the operation mode of front panel conector...

my buddy has this board (asus m3a-h) with 4 x 2gb g.skill pc6400 sticks...

would uping the northbridge voltage help out a little since there is so much memory?

stock is 1.3v right? maybe uping it to 1.3125 or 1.3250?

[Jakalwarrior]

Would just like to say that the latest 90X bios is the first new bios since 40X that didnt trash my overclock! same exact settings are still stable... on the other hand I didn't exactly gain anything by upgrading either lol (I keep thinking some new bios is going to get me 100 more mhz or make it start scaling with voltage).

Hi INFORMAL, and everyone else.

yesterday i stayed 3 hrs trying to OC my PHENOM X4 9750 on the ASUS M3A
the max i got was 2.7Ghz @ 55C Load / ~38C IDLE running PRIME95 for 7hrs

Does anyone else have this CPU & Motherboard and has successfully overclocked it past that point with a moderate heatsink?
I have a CoolerMaster TX2

Ive got my RAM @ 667 set and CPU-Z states the ram @ 408Mhz - my RAM is 4x1GB Kingston DDR2-800 ValueRam
I set the Voltage a tad higher than stock @ 1.26V instead of 1.25v

Please assist, i dont think 2.7 is a good clock above the stock 2.4

[arthur92710]

Did you raise the cpu voltage?

[mr1c3man]

Did you raise the cpu voltage?

yes i did, from 1.25V ( i believe is stock) to 1.265V
i dont wanna raise it more, i think 55C on load is heaps.

but i didnt touch the NB or SB voltage they're on auto
and i didnt touch the NB multiplier its auto,

only thing i done is raise CPU MUlti to 11x
set RAM speed to 667
increase voltage to 1.26V
and set FSB to 245.

but im sure i can get more than 2.7 on this phenom guys.
