You guys need to post in English and whatever so everyone can read it.:D

ive just cut off vid2 & vid3 pins.. tried several pin mod settings and no increase/decrease in voltage

thers gotta be a way of fooling the cpu/mobo to get 1.5v @ default.. in return that should give up to 1.65v in bios..

as u can see im in no mood for a vcore via solder.. last resort

First 3D01 test :

T2600ES @ 3057MHz
X1900CF (mastercard only, not crossfire) non overclocked

wow nice, did you bend clips on the scythe for it to make contact?

dam, I didn't really fancy another pentium-M type of cpu again but seeing that just makes me :slobber:

wiw 3GHZ passive PWNZ...
so does AMD still hold the 3d crown or is it to early to give actual comments yet?

Nope din't bend anything, for in a case its not tight enough but laying down the board is ok.

So maybe you must bend a little indeed if you gona put it in a case too put more pressure on it.

sorry...
two questions... ^^

V/io voltage are originally how much.?

If MOD, is regulated from voltage that is established in bios..?
ex) Vcore(bios 1.3V) + Vcore MOD(?) = 1.3 + (?)

Waus mod cpu
s-pi

pi fast

Put a 507 prometeia on it, normal 478 cpu kit won't fit i had to mod it a little because of the angle'd cpu socket.
can't acces bios like more guy's here, booting is not a problem, its doing that ok.
no mods on the board
so ,.......cooling helps, but not too much..

I've done Vchipset mod...of course by my own method.

hicookie's measure point of Vchipset is not incorrect itself.
But APL5912 is not a controller of FET(Q29).
APL5912 supplies PCI-E voltage, it seems.
Pin3&4 Vout of APL5912 varies according to PCI-E voltage setting in BIOS.

And FET(Q29) is not working for Vchipset but for Vccp.
Vccp is AGTL+ Termination Voltage, described in the Yonah datasheet.
FET(Q29) is drived by ISL6537 with DRIVE2/FB2 pins.
Vchipset is used for input of FET(Q29), as described in ISL6537 datasheet.

Vchipset is supplied from another FETs(Q51,Q52).
FETs(Q51,Q52) are controlled by ISL6612,
and ISL6612 is controlled by ISL6537 with DRIVE3/FB3 pins.
Vchipset is devided with R435&R436 located near South chip,
and the devided voltage is read by FB3.

So, I added 50k-ohm VR between FB3 of ISL6537 and GND.
It works, but higer Vchispet does not contribute for FSB improvement,
at least upto 1.7V with stock heatsink&fan, in my case.

I also tried Vccp, AGTL+ Term. Volt. upto 1.2V, it made no sense too.

Now I removed this VR for Vchipset-mod, but show it FYI;)

thanks, my mistake, i have not mod the vchip,and certify that ;)
thanks,kyosen share much way to mod ths baord.

still wait someone to break to wall,:( or ths baord is dead, wait for conroe on 965?

I hope this is figured out soon, I know this thing is gonna do 4ghz+ in near future..

Really hard top break the wall - but slowly getting there:

There are several potential settings that *might* help to get the FSB, but I post my thoughts in a seperate thread.

nice , any other special thing's to gain that?

270+ fsb is awesome

Mike & Tyrou, can you please take picture @ label on your YDG??

Great results btw :)

Mike, can you do a 32M at exact same freQ?

seeing as conroe has no dramas with 380+ MHz FSB.....it is a bit sad that these are struggling to go past 250-260:(
