This motherboard is Quanta UT3/5. It have different revisions. Only some of them have hardware support for quad cores CPU.

okay, my Revision is: C and my brand is Foxconn    :-)
The complete Model-Nr is:
Foxconn ML 1 (or i ???) - H 94 V - 0
E 253117


Complete on my board its:
DAUT 3 MB 28 C 0
Rev C
UT 35 ATi DDR 3

Try to find some elements on your motherboard and make photos of them:
resistors - R150, R154, R177, R180, R185;
transistors - Q10, Q11.
P.S. Modified BIOS isn't needed for quad cores CPU.

Okay, I found all resistors, photos I will post later after being outside with my dog.

What time is it and where do you live ??? Isn`t it night where you are or very early morning ???   :-)

1. picture shows R 150, under it R 154 and there under Q 10 

2. picture shows R 177, there under R 180, left side (of R 180) is R 185 and under and in the middle of R 180 and R 185 there is Q 11

3. all together right and left hand of the "steel or alu"

Well. This revision (578130-001) of motherboard hasn't hardware support for quad cores CPU.

[ThaGroove]

oh, absolutely no Quad Core ??? Even not the normal Q 9000 and Q 9100 ???
No Quad support is very hard, because the 2 above are listed...   :-(
And then there is absolutely no possibility to use them ???
Or would the pin and cable modification from the link you posted here work for my model ???
Or do you think, I should better leave it ???
Or can you tell me which boards support Quad Core or how they have to look like ???
Maybe I can get one...!?

[DeathBringer]

516294-001 supports quad cores CPU, but it have DDR2
Only hardware modification with soldering missing elements can help to add support to your motherboard.
Find and use a schematics and boardview for Quanta UT3/5 with ATI.

Okay, I will try my luck but I am convinced not to find one, even to get these older motherboards is difficult... :-)
But thank you very much for your support !!!!! Now I know the facts...
Do you know if the extreme dual cores are compatible with this board X 9000 series ???
And greetings from germany

[DeathBringer]

X9000 is not recommended because of FSB=800 Mhz.
Try to use X9100 with FSB=1066 Mhz. It can be simply overclocked by ThrottleStop.

Okay, thank you very much for your support !!!!!
