Hello,
Thought it might be a good idea to share the undervolting capabilities of the 1055T. My figures will be a bit higher than those running their 1055T's at stock speed but this should give you an idea how overvolted they are at stock.
Here are my overclocked figures, speeds, and stock voltages at different P-States:
FSB: 250
NB/HT: 2000mhz
Memory: DDR3 1667 mhz 7-8-7-24 2T 40 1.6v
P4: 1000 mhz 1.225v
P3: 1875 mhz 1.275v
P2: 2750 mhz 1.325v
P1: 3500 mhz 1.375v
P0: 4000 mhz (turbo) 1.475v
Adjusted votlages via K10Stat and Prime 95 stability testing:
P4: 1000 mhz 0.7875v
P3: 1875 mhz 0.9625v
P2: 2750 mhz 1.1375v
P1: 3500 mhz 1.325v
P0: 4000 mhz 1.475v (can't test for stability so left voltage very high just in case)
I was able to originally test for stability at each P-State with the following values 0.75v, 0.925v, 1.1v, 1.3125v but could not remain stable when the clocks were adjusting themselves between P-States.
As you can see, stock speeds of 2800 mhz may only need about 1.1375v to 1.15v to run stable and I believe it is possible to boot 800 mhz at < 0.70v.
One thing I almost forgot to mention, the Prime 95 stability testing was done for 15 minutes with P-States 2-4 and for 1 hour with P1. I felt that the slower speeds needed less testing since the processor will not allow the lower P-States to operate at 100% without bumping up to the next P-State.
Finally, if anyone has any idea how I can test P0 for stability that would be great because I seriously doubt it needs 1.475v to run stable.
