Looking that way. He is pretty close to getting stability though.

I lowered the CPU I/O to 1.15

current setting:

VCore: 1.47V
Vdroop: Low Vdroop
CPU I/O: 1.15V
CPU PLL: Auto

bah..probyn beat me to it..but yah..cpu pll @ 1.835
TBH I don't use the ..ahem..in-house info for sb overclocking..there's some umm..discrepancies there..
also..what's your dram voltage?

wai wait I/O 1.39??? I thought max for that is 1.19??

Pll is currently Auto.

Current:

VCore: 1.47V
Vdroop: Low Vdroop
CPU I/O: 1.15V

Ok bud...you run yours that way. Each one is different correct?
See my realtemp VID at 4.8? That's why I told him that...check yours next time...

Can anyone confirm the max for CPU I/O is?

Current Settings:

VCore: 1.47V
Vdroop: Low Vdroop
CPU I/O: 1.15V
CPU PLL: Auto

VID is unique to every Batch of CPUs and it doesn't really apply to this point. It was a reference to voltage at the highest turbo on all cores, which I think is 3.8 GHz for a 2600K.

VCCIO or CPU IO Voltage is for the Integrated Memory Controller and while it may need a 10mV bump, I don't believe 1.39v is necessary nor safe.

CPU Vcore is what is, or should be, needing to be incremented when failing the Small FFTs test.

Now, I asked you to further my knowledge about IMC, not to make you feel like I doubt you, I just wanted to know why he should push that much voltage through his IMC when he is stress testing the onboard L1/L2/L3 caches and CPU Frequency and almost zero memory.

I know I wouldn't run that voltage through my IMC, so I will not recommend someone to do something I wouldn't do.
