Problem Classified 3

[Vinsent]

Hi all...I have a problem with the voltage IOH ....
Over 219 blck and set 1.200 IOH voltage the board crashes on startup.
Under the 220 Blck,i set IOH smoothly over the 1,200-1.350
231x15 no problem whit IOH Voltage at 1.175
220x15 crash in bios at IOH Voltage 1.200

My system is...

Classified 3 bios 77
xeon w 3520
gskill trident 6GB 2000MHZ
Nvidia gtx275
1x ssd crucial c300
2x velociraptor in raid 0
Power 850W Arcangel

this is my template....

Thank you all for your suggestions.....

IS it worse if you set QPI signal comp (auto)?
if so then offset QPI signal comp even lower than (less) by moving JIOH to the other position.

Good afternoon ....
She now has filled my heart with joy ....
It is an honor for me to speak with a living legend...
thank you so much I solved by moving the jumper IOH to another position and set Auto Qpi Signal.

Thank you so much .......


Edit.....

Now 228x15 no problem whit IOH Voltage at 2.225.
228x15 whit IOH Voltage 2.500 crash....
Thank you so much ......

ok good jumpers are FUN!

Hello Legend....
In your opinion why do not I give more voltage on Ioh
is the fault of the processor or other?
Thank you very much....
