1055T Voltage + Overclock

post #1 of 21
Thread Starter 
How do people get there 1055T's running at 4.0GHz at less than 1.5V? some people are running them at 1.47 or 1.45.... and less... and mine will only stay stable at 1.5V without getting errors in Prime95.

FSB 286MHz
CPU 4004MHz @ 1.5V
RAM 1524MHz CL7-8-7-24-28 1T @ 1.65V
Northbridge 2860MHz CPU-NB @ 1.37V - NB @ 1.28V
SB/HT 1.28V
CPU-PLL 2.5V

Turbo Core Disabled, Cool n Quiet Enabled, C1E enabled, Virtual Machine enabled.

different motherboards and psu's have different voltage stability.
also every processor performs slightly differently than every other, even if the same model and batch

EDIT: I see you have 8GB of RAM if that is in 4x2GB sticks then you will need higher voltage to run the memory controller with the extra load from 4 sticks of RAM

BSOD's until i get the VCore back to 1.5V, only get BSOD's when I when Prime95 when my voltage is lower than 1.5V

do you have 4 sticks of memory, the additional two sticks will require the increase in voltage, otherwise the memory controller and or cores will not be properly powered

with my FSB @ 286MHz my RAM runs at 1524MHz @ CL7-8-7-24-28 1T 1.65V do I need to bump the voltage?

your ram voltage is fine. but the phenoms have a memory controller in the cpu. with 2 sticks of RAM, 1.45V CPU voltage is attainable. With 4 sticks of RAM the memory controller (which shares the CPU voltage) requires more power, therefore you need to give your CPU 1.5V

Yeah, I have 4x 2GB G.Skill 1600MHz RAM, and there's no way I can get my CPU voltage under 1.5V then?

not unless you get rid of two sticks of RAM, its one of the few limitations of on CPU memory controllers

Dammit, I'm gueesing my 1055T would have a short life with 1.5V then.

Need to get the Rasa kit to cool my CPU more efficently
