ABIT Fatal1ty AA8XE volt mod request

Hi! guys,
someone can help me? I would like to voltmod my Fatal1ty AA8XE (vdroop, FSB etc..)
Someone can help me?
Thanks in advance.
Bye, Andrea.

Pot a picture of the board :)

Thanks CaTalyst.

I post a link from a pictures by HardOCP.

Whats written on the ICs i circled, and can u take closer pics of the areas those ICs are in. Also mayhave to remove the otes.

Can you get photos of the areas I've circled. I don't know if you want a Vdimm mod as well, but I've circled a possible area for it anyway. I can't see any Vcore regulator on that picture, but it might be one of the chips I have marked.

Edit: oops, CaT got there first!

Hi, saw CaTalyst.X referring to this post over at extremeoverclocking, well this or another Vold mod post.
Anyway, I have the Fatal1ty AA8XE and didn´t have much to do so I took some pictures :) I couldn´t reach 2 places due to huge HS and GPU coolers :(

Here´s what I got so far:

Many thanks skuliaxe, well done.
You save me from take my old camera and get photos ;)
Hope CaTalyst.X could be help me.....

Can you tell me what is written on the chips I have circled. These will probably be controlling the Vdd.
Also, can someone try to get a picture of the area under the 16x PCIe slot please.

I´ll get into the following tomorrow;
1) More pics of the circeled areas, with better resolutions.
2) Take my Gfx card out and get a good pic there...

I can´t get a pic of the CPU area though :( My HS has a H metal bracket that covert that whole area!

heh, could have taken the pics with the IC Markings up so I could read them :D

Me too :)
This afternoon I post my images.
Come on guys, let's voltmod this motherboard!

IC markings? Don´t understand...hehe

Anyway, got a few more pics here.
..::Warning to 56K modem speeds, each pic is about 1.6Mb::..
I uploaded the stock photos to a host so I don´t have to reduce the size/quality...

Pic "mr.big" shows why I can´t get a good pic of the cpu area... :rolleyes:

Great skuliaxe!

And great "Mr.Big" ;)

The writing on the chips, those are called IC markings. They tell you what the chip is, who made it, and what it does.

I think the Vdimm and either the Vagp (or VPCIe or whatever it is now), Vdd or Vfsb are controlled by W3302s's. I can't find any datasheet for this chip, and without the datasheet its very hard to find out which pin is the one you need to do the mod on.
I think the Vcore regulator is a HIP6302, but I can't see that chip on the picures anywhere, so its probably under MOSFET cooling thing.

If I can get the datasheet for the regulators there shouldn't be any problem with finding the mods, but I've emailed winbond twice to try to get the data sheets and I haven't got any response yet :( . If someone can find the HIP6302 Vcore regulator I will find the droop and Vcore mods.

droop mod for both AA8XE and AA8XE Fatality would be awesome :)

indeed it would...
would this mod be the same for the AA8 duramax aswell? or should is start writing down some IC's for you guys...
my cpu cant go farther with out a droop mod...
and my cpu isnt' down for high FSB with a 20X multi... (anyone got a cascade for this thing? :p: )

I Hope Winbond will reply to you....
By now I thank you very much for your efforts ;)

Could you help you?

http://www.alldatasheet.com/datashee...IP6602BCB.html

P.S. AA8 does have W83302s's. Peraphs mod is the same.... (sorry for my poor English).

Bye, Andrea.

any news????

I've emailed Winbond 3 times now, and I've had no reply. If you can find a mod which uses the same chip I should be able to adapt the mod to work with this board tho

Many thanks persivore for your kind collaboration.
I've emailed to Winbond too. No reply :(
I'm searching.....

Would it be possible to get voltage readings at each of the pins on the chip so that I can try to work out which pin might be the mod point. I've also posted this in another thread, and if I can get the voltage readings from 2 different boards using the same chip I should be able to compare the voltages and find the right point.

Hi Persivore,
sorry for my delay.....
Tomorrow I try to get voltage reading of each pins on the follow chip:

http://www.xtremesystems.org/forums/...chmentid=28585

Many thanks for your efforts.

Thanks :). I think I know which pin is the mod point on the chip, but I can be more certain if I can get 2 sets of readings.

Hi persivore,
here my voltage reading...

first the 83320s chip near DDR slot:
http://img213.echo.cx/img213/9378/83...slot7vu.th.gif

and then the 83320s chip near Northbridge:
http://img213.echo.cx/img213/6291/83...arnb8lg.th.gif

Hope this could be help you!
Bye, Andrea.

I'm 99% certain that I know which pin is the mod point. On the Vdimm regulator, can you check the resistance between the pin I have marked and a Vdimm read point (e.g. pin 7 on the dimm slot). Can you also get the resistance between the pin and ground.

Sorry but I'm not an expert of voltage readings etc..
I ask to my friend (he is a very expert) to reading voltages you require.
If I've understand, Vdimm regulator is winbond 83320s chip near DDR slot, you confirm?
Bye, Andrea.

Yes, the Vdimm regulator is the winbond 83302s chip by the Dimm slots.

Ok ;)

Damn..... my friend is in holiday this week.
I must wait he return :(

Unfortunately winbondwill never send out PDF to end users...

Ill see if I can find out any more about that chip.

Hi Persivore,
since my friend is in holiday (as I told you) I would like to try to myself.
Please help me and confirm if my steps are corrects.
First of all I must set my tester in OHM reading mode right? What scale should I use?
My PC must be unplugged by A/C right?
After that, I point my 2 tester tips (red/black) one in 83320s pin you marked and one in pin 7 on the dimm slot right?
Also I point my 2 tester tips (red/black) one in 83320s pin you marked and one at ground (ex. chassis on my case) right?
Please confirm my steps and sorry for my poor electronic experience.
Bye, Andrea.

Yes, thats right :). Try setting the multimeter to a range of about 20k ohms. It shouldn't matter which way around you connect the multimeter leads either.

Thanks Holst. I think I know which pin is the feedback pin, but having more information about the chip would be good :)

Here the resistance reading:

Tester setting: 200Kohm reading mode.

Resistance between the pin you have marked and pin 7 on the dimm slot: 50

http://img256.echo.cx/img256/1993/vd...7ddr9fl.th.gif

Resistance between the pin and ground: 50

http://img256.echo.cx/img256/8104/ground7xr.th.gif

It seem that resistances are equal ;)

Hope this could help you.
Bye, Andrea.

Thanks for the readings. They are about what I expected. I think that this should work for the Vdimm mod: Conenct a 1Mohm (1 meg ohm) varaible resistor between pin 7 on the 83302s and ground.
I'm 99% sure that this is the correct mod, but be careful not to set the variable reistor below about 200k if you don't get any Vdimm voltage change. If this mod works, I will work out the other mod for the other 83302s chip near the northbridge.

Ok, next week (when my friend return from his holiday) I try for vmem and I will post the result after.
Bye and thanks, Andrea.

Hi! Persivore,
my friend has return from his holiday so I'm ready to vmod ;)
Please confirm PIN7 on photo
http://img67.echo.cx/img67/4128/aa8xeddrvmod9pg.th.gif

From my previous voltage reading I have 2,84 on this pin.
http://img213.echo.cx/img213/9378/83...slot7vu.th.gif

That's all ok? Can I proceed?
Bye, Andrea.

Sorry, I got the wrong pin in post #39. I meant pin 10 on the winbond chip, and not pin 7. Pin 10 is the pin which reads 1.19v from your readings, and as shown in this picture.

Ok, perfect!

Good luck! I hope it works :). Just remember not to set the variable resistor below about 200k if you don't get any voltage change.

Could you please measure from the yellow line I've pointed onto the rounded choke(coil) to which Winbond IC leg is shorted or have a small resistance?.......
