CPU voltage

post #1 of 9
Thread Starter 
i've been playing around with some setttings trying to get a feel for and learn O.C.ing. Right now i'm at 3.6Ghz with a Vcore of 1.38( PC Probe II) CPU offset voltage is set to auto. My questions are:

Can i leave offset voltage to auto?
If i do manually set the CPU voltage do i need to change the " CPU&NB voltage mode" to manual or leave at offset?
The idea is to get the lowest possible voltage (stable), right?


idle cpu temps are about 28-30C. Also i haven't ran Prime95 yet.

i have mine set to manual.
My cpu vcore is 1.28v @ 3.6ghz and my cpu-nb is 1.36v @2800mhz
at auto your vcore should be at 1.30v

Im kinda new myself to overclocking so i cant be that much of a help Sorry.

thanks anyway, my biggest concern was my 2nd question, i have read where some left it to offset then manually changed voltage and about fried their cpu.

1,28v for 3,6? Thought stock was 1,325. And you can get 3,6 on stock, since 1090t is basicaly a 3,6 downclocked to 3,2.
You can leave it as it is, but if your goingto approach the 1,5 - 1,55 voltages , then you should put it on manual , to get the OC stable, you can go manual before, tbh it wont really fry your cpu like this.

Tbh, dont worry so much about it , with that beast motherboard and cooling, you can go waaay higher but ask yourself if its worth it stressing the cpu that much to get those few extra mhz, sure it sounds good in benchmarks, but in reality do you rly need it? Thats why 3,6 or 3,8 is nice since you dont need to change le stock voltage.

he should also be able to go below stock volts with at least a clock of 3.6.
unless im just lucky.
when on auto cpu is listed as 1.30v in cpu-z

From what i have seen so far the newer 1090t and 1100t can run on like 1.3v and still achieve a reasonable overclock, no reason why it would not work for you, try 1.3v at the 3.6ghz and see if its stable...if it works you only gain, same oc speed and u'll run cooler

Try working with these settings in your bios,
Ai Overclock Tuner to Manual
AMD Turbo Core to Disabled
PWM Phase Control to Full Phase
CPU Load Line Calibration to Full
CPU/NB LLC to Full
Extreme Overvolt to Disabled
CPU and CPU/NB Voltage Mode to Offset (this will allow you to use Cool & Quiet)
CPU Spread Spectrum to Disabled

Work towards raising the CPU/NB Freq as high as possible
Maintain HT Link at 2000 MHz (+/- 100 MHz)

And your second question is NO running the Offset voltage in manual will NOT fry your CPU. Just watch your temps under load, as well as your Vcore under load which should stay under 1.5-1.55v.
