Hey 8 Pack

Im quite happy with my 4.6ghz turbo overclock as it is only using 1.28v under load and the temps are great. My question is, what should my voltage be when idle. My voltage is around 1.056 when idle. is this correct? If not, what can i do to make this decrease to something lower when Idle.
I read somewhere that this is quite high for an idle temp and should be around 0.96 or so.

any ideas?

Your using offset so the idle is dictated by the CPU plus the Offset you add to make its stable when its at full speed. You could add negative offset but then you wont be stable at 4.6ghz.

What your experiencing is normal.

Thanks for reply. I had thought this was ok. I just had suspicions that it was high at idle because of other material i have read. I use +0.015 offset and High LLC giving me 1.28v under load. My system seems to be much quieter since I made these adjustments.

On another note 8 Pack, I notice when I start a stability test or start a game that my cpu fans ramp up very fast then slow and settle. They didnt do this when I used the chill control software, The fans gradually increased in speed. Since I started using the Bios to control fan speed, they started this odd behaviour. Its like the fans go turbo then slow quickly and settle to a quiet speed. Im not sure if theres something i can do about this. I have ordered apache fans which will make it much quieter as the stock antec kuhler fans are 2600rpm and really loud. Your opinion appreciated 8 Pack

I don't mean to Hi-Jack the thread i just want to ask MR Pack something related to this:

My Voltage is Higher when Idle (on CPU-Z) than when loaded. For Example: Voltage set at 1.220 in BIOS, Idle Voltage is 1.270 at load it's 1.220~ish is this normal?

Seems like i do have an offset voltage but i can't find an option for it in my BIOS..

Thanks and Sorry.. :)

What LLC setting are you using? It seems like a big difference for vdroop, but it could be if you have LLC on a very low setting. Either that or if you have negative offset volts set somehow? What board are you using?
 
Very High LLC is most probably the cause of this. Remember Intel designs teh processors with a certain amount of Vdroop inmind as this logically extends the life of the processor. Lower the LLC a couple of notches so as your load voltages are slightly less than idle.

Z68MX-UD2H (i think).. Gigabyte :)

I actually mis-wrote. I set the Voltage in the BIOS at 1.200 and get 1.272 Idle and 1.260 Load voltage..

Gigabyte work with load line (LLC) levels..

I have mine set to level 4.. I can't go any lower as i get BSOD and using higher levels raises the Idle and Load voltage..

The levels go from 1-10. :)

Any help? :)

2.2 volts ??? At -100 that mens dead CPU never mind ambient cooling. Something is wrong with that one. Do you mean 1.2 V??? If so and the system is stable leave it. your voltages are within tolerances. The system is stable. If it aint broke dont fix it.

I did mean 1.2 and i just changed it. Thanks..

now that I have a nice temp and voltage at 4.6ghz, do you think I should raise my ram to 1600mhz again? or should I keep it at 1400mhz so that the imc has a little slack?
the ram is rated at 1600mhz 1.5v
 
Raise it to 1600 and retest with prime for stability, should be fine ensuring youuse the ccorrect voltage and timings
 
I have left the timings at 9 9 9 24. ill adjust the frequency and see how it goes ;)

Also, I have the CPU :DRam ratio set to auto. Is this correct or should it be set to 100:100

(Memory overclocking and settings are a little confusing to me)

Auto is fine. I never touch this setting and neither does several other pro clockers who I am good friends with.
