Strange OC for E7200

Ok So I bought E7200 on Saturday and the OC results have not been very pleasing. 4 Ghz is elusive. It just wont load Vista even at 1.55 volts. But here is something unique. I am finding it very hard to find a stable OC at 3.5 Ghz with 1.4 Volts using 9.5 multi. However if I lower the multi to 9 or 8 I can easily OC to 3.5 Ghz under 1.4 Volts. Why is 9.5 not being stable? Has anyone else experienced this. I am running GA EP35DS3L with latest bios.....

Though official proof is needed, unofficially I am 14th on the Super Pi leader board with 13.32 as the lowest score achieved. Since its far from my highest OC, didnt bother taking screen shots. I plan on going to water, and hoping to go sub 13.
 
Volts over 1.36V

R u planning to fry ur chip....u gave it 1.55V too :S .....

Are u using the water cooling.....

Still 1.4V is high IMHO
 
Try Rasin the NB voltage to 1.4 For 400+ FSB and yea it preferable to let the Multi be at 8.5 or 8 :)

I have my E7200 @ 3.8 , 8.5 x 450 @ 1.21V
 
This is strange, Real Temp shows load temps of 58 degrees after 2 hours of Orthos with 1.5Volts. Which is safe enough.... At 1.35 volts its not stable even at 3.3 Gs.

Why wud u run it at 1.5v? RealTemp sets the TJ at 95 make it 100 to see the real temp.

TJ for the 45nm is 95º not 105 :clap: Also Legitreviews and many sites think 1.5V is safe voltage for 45nm chips. But this is debatable. Anyways I do 1.5 for just benching, short time. I have it running stable at 3.4Gs at 1.3875 V which is safe as per my standards.
 
Its 100C as Nash mentioned :)

Desktop TJ For Dual and Quad Core CPUs

45nm Desktop Dual-Core Processors

Intel Core 2 Duo processor E8000 and E7000 series - 100°C

45 nm Desktop Quad-Core Processors

Intel Core 2 Quad processor Q9000 and Q8000 series - 100°C

Intel Core 2 Extreme processor QX9650 - 95°C

Intel Core 2 Extreme processor QX9770 - 85°C

AnandTech

1.5v was not safe for 65nm, 45nm r too far. On air cooling max 1.4v for 45nm.

can u see the voltages in cpu-z and everest as those are the ACTUAL voltages

maybe the difference between what you set in the bios and what it really supplies is quite high
