q6600: lower VID = better?

post #1 of 10
Thread Starter 
i have currently got a q6600 with a VID of 1.325v.

my friend, who has 1.2125 (or 1.25, wasn't clear on the phone) q6600 said he will be selling it, he only overclocked to 3.4Ghz once, all other times are 3.2Ghz.

my current CPU don't have any sort of walls, i can hit 3.9Ghz with enough voltage through my RAM, and extremely loose timing. and i plan to get the OCuk's G.skill PC2-8000 RAM, hopefully hit 4Ghz with my friend's lower VID CPU.

so is lower VID = better CPU, no FSB/overclock wall, and guaranteed lower voltage for same overclock??

IF i swap CPU with my friend, (aka, me going from VID 1.325v to 1.21v) will i be able to get higher clock or hit some form of FSB/overclock wall??

in another word, do lower VID tend to have some sort of overclocking wall at higher frequencies? (my goal is 4Ghz on air)

Lower VID tend to overclock better.

BTW you wont reach 4ghz...

Theoretically it will overclock better and require less volts for the same speed than your current one does.

A basic CPU water loop and its very possible, even on air if you have a golden chip

are there any possibilities of lower VID have some form of overclocking wall, where it will require to add ridiculously large amount of voltage to get pass some frequency, thus making me swap CPU pointless?

my current CPU can happily do 3.8Ghz, and all voltage increases seems to be linear from 3Ghz to 3.8Ghz, add 0.2v every 200Mhz. (may seem a lot, it's Abit iP35 Pro, it's got a huge vdroop)
and besides, im not looking to run 4Ghz 24/7, only need it to be stable enough to complete 3Dmark06 and SuperPi.

situation is, my friend has found a buyer (not on ebay, amongst his friend) he is going to sell his q6600 after Easter break. he has also agreed to me that if i want, we can do a swap, and he will sell my CPU instead.
now, keep in mind my CPU has VID of 1.325v, his has something below 1.25v should i swap with him?

I could hit 4 ghz if I lapped my cpu+heatsink... 20 degrees difference between my cores at load! 1.2375 vid

I've actually had both a 1.3xx and a 1.2125 VID Q6600 and all I can say is that they overclocked about the same. The 1.3 got to the same clocks at higher voltages, yet for some odd reason it ran way cooler than my 1.2v. Also, the 1.2 didn't like high voltages at all. The most I've hit stably was around 1.47v, and the 1.3 did 1.6v+ no problem. Then again there was a 10 degree difference between the cores at load, so maybe lapping the 1.2vid would help.

Can you ask him to try it for a few minutes before making the trade?

Other than that, it's your call really. Both of mine did 3.8ghz stable, but I didn't take them any higher due to temps.

well i had a e2180 with a vid of 1.325 but would still do 3.6 and my e6600 has a vid of 1.2135 i think and will do 4+

many thanks for your input!

i may just put his CPU into my mobo, have a try, it it's good, i'll keep it, if not, i'll ask him to sell his CPU. we are good friends, and he don't mind it, as he's really rich, he plans to get Q9450 after Easter anyway.

i don't know about trying using his computer, as he's only got a Zalman 9700

Mine is 1.3 and does over 4ghz.

Fully stable at 3.9ghz which is pretty good for a Q6600.

So its not all about the VID.
