Thanks for sharing cookie :D

Vcore offset is for increase vcore?

yes, using offset to increase vcore
such you set 1.9v in bios, then change feedback resistor lower
then vcore will climb upper. once you done
for example,

bios ---- real output vcore
1.90 ---1.95v
1.80----1.80v
1.70----1.70v

then you done the offset 200mv(use the mod)
bios------real output vcore
1.90v------2.1v
1.80v------2.0v
1.70v------1.90v

have you hit the OCP? the board shouldn't face the OCP when you using
Clarkdale. here is the tip, to let you understand when board face the OCP.
OCP behavior---------------> shutdown & restart.

Thanks hicookie

thanks a lot :)

i think he meant i7 chips probably

i wouldnt use OCP mods on these mia.......they will die pretty quick without that protection and you can hit 4Ghz without OCP anyways

You think I'm worried about killing a $100 board after killing 4 980Xs :rofl:

Anyway, OK....I'm still a few weeks from trying Lynnfield in it, I'll keep you posted :up:

hahah good point mia

Ok miah lets get this worked out. I have one educated guess so far.

I don't have my camera atm but I need a high res shot of front of board near ITE controller if someone would be kind enough to post one.

:ROTF: ouch, such fool to me, i forgot to post the measure point of voltages
sorry, everyone:rofl:

Am i clearly telling you this board is 2 phase VTT, 4 phase vcore and 1 phase vAXG(IGP core) from the picture.....lol

here you are. :D

thx cookie :up:

thanks hicookie:up:

Would it be possible to get points for vdimm ?

Then i hope that we can get better scores this weekend.

Without mods - 5.6GHz @ 230blck cb @ -70 cbb @-65

Thx for posting this... This will actually give me a chance.... 1.49v for 200bclk 1:5 ram.... I hate this i7-870 IMC :-/

Give me 1.58v, and it should work the magic!
But... 20Kohm, thats a headache, will check if they have something with less resistance. 5Kohm or somethin'

any idea where is the vdimm measurement point???

just poke around the dimm slots with your dmm im sure you will find a read point pretty quick mate.......

ok boss =)
peter contacted me about the ln2 supplier... hope to see him soon =)

hicookie

the resistor is already 5k-ohms ... its not 16.7k-ohms

is this a new revision board? my board came with F2 bios.

i already have the isl6344 datasheet ...weird that the resistor is 16.7k-ohms
