Hopefully next week ill have a new PC, with a GA-p45-ds3 and a q6600.
Now i have a few questions.
1) what is the so called STOCK voltage for a q6600 (go)
2) will the chip reach 3ghz on this voltage or will i have to tweak it as this will be a first time over clock.
3) do i need too set the pci-e frequency too 100mhz so it doesn't break my card ? and if so is this the same for pcie 2.0
4)any other things i should know before i attempt this so i dont break a brand new pc? such as north bridge etc.
2) Some people say they can get to 3.0 GHz on stock voltage, but from my experience I have had to up the voltage to 1.425 to get it stable at 3.0 GHz, and I have the GO stepping version. All processors are different.
3) Leave the PCI-E frequency at 100 MHz, the performance gains are virtually non existent and you will be risking data corruption. (regardless of PCI-E version).
4) Only change one setting at a time when overclocking, and make small steps. Test your memory, use an aftermarket cooler, remember case screws, check all connections, be patient, have fun.
i just OC my q6600 to 3ghz without touching the voltage... i have an IP35 pro MOBO that defaults the cpu at 1.3v. just brought the FSB to 333
im not sure about PCI frequency but i would also like to know
Hey the VID is actually different depending on what chip you get. So stock voltage will vary. Lupiron knows better than me, but I believe the range is from 1.2 volts all the way up to 1.32 or something like that. So somewhere in that range is the stock voltage for your processor.
Open Realtemp and you will see your VID, which is the voltage your mother board will set it's self to, when using the auto setting. That value can be considered stock voltage, and is what Intel believes your chip needs to run stable at factory rated stock speeds. But we all know that can be stretched a bit.
Yes the board with read the VID value and automatically set the voltage to that value when running on auto. And yes a lower VID is better for overclocking technically. It just means you may have a harder time pushing a real high overclock because of voltage and heat restrictions.
Reason is you need less voltage to achieve frequency value X, relative to your counterpart with a higher VID.
i have nooo idea where you brought those voltages for the q6600, me and my friend own this cpu, our stock voltage is 1.225 v, our motherboards are p35-ds 4 and 965p-ds3 respectively. i can get up to 3ghz on stock voltage and the pc is stable, i run few benchmarks and no worries. then i moved to 3.6 ghz and i had to move up the V to 1.4.
Your motherboard when overclocking Lock the pci express frequency , pretty much all recent motherboards do that automaticaly, you don't have to worry, the pci express will be lock at 33mhz for your gpu. and that 100 mhz won't be touch unless you specify that in the bios of course.
get Cpu-z or Easytune for gygabite owners to have an accurate idea of your voltages
Hi, my q6600 has a VID of 1.325 and I have gotten to 3.0 on stock Volts with a NEO F P35 board. Tried for 3.2 with 1.350 but a core failed after 2.5 hours of prime 95. Am I okay up 1.4 V assuming temps remain okay @ 60C under load? Also according to cpu-z the voltage the cpu is getting is less than what is specified in the BIOS. vDROP Vdroop I assume?
1.2 to 1.5 is the voltage range for your processor. Where you keep it is up to you, at perhaps a risk of shortening the life of the processor. So it's up to the user's discretion.
Vdrop is the initial drop going from your bios to windows. Vdroop is the difference between idle and load voltage, as measured in windows.
Personally I feel safe to around 1.4 to 1.45 in cpuz, provided the temps are ok. I look at it this way.. If the thing dies in two years(which it won't) , a very cheap replacement will be available, because the tech would be 3 or 4 years old. The q6600 can be had for around 170.00 USD now. So crank that puppy up!!
