? regarding low VID q6600 and OC

I've got a q6600 with vid 1.2125. The highest stable oc I have achieved is 3.4 at 1.35vcore +.2nb and +.2fsb with idle temps in the low 30's and high 40's-low 50's running prime95. I have had it up to 3.5 but it took 1.6vcore and idle temps were 58-60. From everything I have read this doesn't seem right. I know increases in speed require exponential increases in vcore and I know every chip is different but it seems like I should be able to push this chip a bit higher. My systems is:

q6600 go
ga p35 ds3l
4gb corsair dominator pc6400
Zalman 9700
Antec 900

I'm certainly not disappointed with 3.4ghz but I am curious, if there is a valid reason, why it won't go higher.

How about you establish if your board has a large VDrop and droop first?

Put the thing at stock, disable speedstep, and manually set the VCore to 1.2125 and re start.

When you hit windows, look in CPUz and watch for your Idle voltage. Make note of the highest it flickers, and then run prime 95 small ffts on all 4 cores, then list what CPUz says your VCore is while running prime for at least a minute. List the lowest value it flickers to.

Your chip by itself will need around 1.3250 volts while loaded to get 3.6.

Just be sure that damn speed step is off!

kinda agree with the above.

although if u managed to get 3.4Ghz. ill be happy. if u really wanna to pull its leg to the extream. then do it when you ready to buy ur next cpu. burn that chip with whatever.

after all. 3.6Ghz is like the pretty high for Q6600 and not many pple running it at that speed.

BTW, if you have a 1.2125, its the second lowest VID for that series, only beat by 1.2000, and I have one! My 1.2500 gets 3.8 right at intel spec 1.5000. So it's not the chip!!

Hey there, Wolf!

@Lupiron You have 1.2 or 1.2125?

I have a 1.2000 VID, gets 3.6 at 1.312 volts, loaded. The next one up is his, 1.2125, they go up in .0125's.

mine is 1.3125

btw, intel spec is 1.5volt?

Yup, the max rated voltage is .95-1.500 volts to remain within intel spec for the q6600 series.

cools. wish i got one of these low VID ones. :(  but as i said. ill overclock it more when i feel like getting slowed down. :)

Bah! Go for 4ghz. I have a 1.312vid q6600, and was able to get prime95 stable at 4ghz, although on a high 1.65vcore. That low vid chip is wasted on you. Shame on you! :na:

Yee haw! 1.65!

i had to save up like 3 monthes to get this pc. so u can imagin how scared i am to do any thing to it.

but in time. im gonna do it. ill go as high as possible. just waiting for the right time when i have enough money to burn this chip. :)
