Hi,newbie in here in overclocking,
I use q6600 and mobo p35ds3l.
Quick question,is it normal the vcore is drop during stressing?
Because using cpuz,the idle voltage is 1.23v eventhough in bios I manually set 1.275v.Then,during stress the voltage reading is 1.20v.
Is there tools that accurately read the vcore?

Sorry,what do you mean?

Got it.but when I push the proc to 3 GHz then run prime 95,after several minutes, the core number 1 is failed the test.
it prompt message like this,"FATAL ERROR: Rounding was 0.5, expected less than 0.4
Hardware failure detected, consult stress.txt file.",
Any comment?During this,the vcore I set to 1.2815v if not mistaken.

Just change mobo,still run prime 95 at 3GHz,seems stable.
Vcore set to 1.2815v fsb 333MHz

you mean,at 3GHz,this proc can run at stock voltage?

Hi,I set to stock voltage which is for my mobo it detect at 1.275v.
And run prime 95 for about 4 hours it is still stable.
But,after I shutdown the pc,and switch off the power at plug,
Then when I want to turn on the pc, it behave like this,
When I push power button,the pc is on for several seconds and then shut off by itself,
Then after several second it will turn on back again and boot as normal.
It is normal?
Sorry if out of topic.
Thanks

only when I turn off the socket power,
If the socket power is turn on,it can boot normally.

Same,for both condition,
It is only okay if I not overclock the proc.

Fuuhhhhhh!!!
I thought the board is faulty or what,
Also thought the bios is corrupt and flash with new bios.

Hi,I am also newbie,
look at your spec, first you need to change yours cooler since the stock cooler performance is already poor at stock condition.
then,your psu must be solid, I got experience overclock using cap ayam psu and the board is broke.
For the vcore,every chip is different (correct me if i am wrong) and the reason to tweak the vcore is to archive stability at during overclock at high frequency if the stock vcore is not stable.
and, during overclock what I read, we need to disable the power saving feature such as eist,thermal and sort of thing plus the vcore we manually enter.
Just some tips that i read in the internet.

Why do we need to disable this option?
What will happen if we enable this option?
Next question,
which one more faster
example q6600 has 6-9 multiplier,

333*9= 3GHz FSB 1333MHz
or
375*8=3GHz FSB 1500MHz?

If the extension cable size is smaller than the psu cable I think maybe can effect.Did you check the cable,is it hot or not?

If not mistake,small cable can't handle large current,
So maybe the cable bottleneck the current draw to your mobo.Usually the cable will become hot if it can't handle large current.

I maybe wrong,but try confirm back by exclude the extension cable.

Just buy this proc,
need to find better cooler, since idle is at 36-40 and the temperature ramp up so fast if open an application.
But at stock speed,and run prime 95 the max temperature is 55C using Zalman CNPS9700.
I try crank up to 3.33GHz by adjusting the multiplier,max temperature is 60C same cooler.
But 3GHz is enough for now

Water cooled,need to change casing first,cm690 need to modify to place rad,pump and etc,lazy to mody.
You looking quadcore?I sell one at my signature

Hi,
Why the reading is different?
[attachmentid=3048602]
I only increase the multiplier from 9 to 10 and the fsb is stock,at 333MHz.
Any comment?
This is not happen if the multiplier at stock which is at 9.
