I seem unable to get my Q6600 to overclock past 3.4. It has A VID of 1.325.

I could possibly swap my processor with a Q6600 that is installed in a box in work, The VID on that one is 1.285.

Would there be any benefit, would i stand any more chance of being able to get a higher overclock, or is it more likely my mobo or memory is preventing me from getting higher???

Thanks in advance

In general lower VIDs = Higher Clocks

I had a graph in the Quad Core Database showing Vcore vs Clockspeed with a VID adjustment for all the posted clocks in that thread which had the relevant information not sure if it is still there was posted a while back
 
Your cpu has one of the higher VIDs in the range...

Generally speaking, the lower the VID, the lower the temps, which in turn usually means more overcloking headroom (this is not always the case, but generally speaking, it is)

Best bet is to swap them over and test, keep the best one, as i assume the one at work is just sat running at stock.

Your board should be able to cope with higher clocks no problem, but your memory is overclocked (im assuming it's 800mhz stock...) Try knocking the devider down to run the memory slower, and see if you can push the cpu clock any more.
 
Pneumonic, thanks for the link will check it out.

Viper, could you please tell me how i knock the divider down (still a noob newbie at all this overclocking stuff, but getting there!!), and yes, the one in work is only 2 months old and just runs at stock, so should be fine
 
Sadly i don't have any experience of that motherboard, but the devider is basically the ratio at which the ram runs compared to the cpu, and can be expressed in many different ways depending on motherboard.

it could be expressed as a ratio, in which case, yours will be set to 1:1 (cpuFSB : dramFSB = 425:850[which is 425mhz real])

And now that i've just typed that out, i have just realised that there are generally not any deviders that allow you to run the ram any slower.

Could you not set the multiplier to 9 and lower the fsb to 378 to get 3400mhz and then work on pushing the fsb up from there?
 
I have the same Q6600 as you mate with the crappy VID of 1.325v. I run 24/7 at 3200mhz (1600, 8x400), I can boot and benchmark at 3300mhz but at 3400 and 3600mhz, it's only windows and superpi stable, prime96 and OCCT both fail or crash the system

After hours and hours of mucking about, I've found 1600 FSB with 400x8 with the memory 1:1 is pefect... however, when I increase the CPU it starts failing prime95 and OCCT v2.0, which is a bummer.

However tonight is the last night of tinkering... and I'm going to take the ram out and leave just 2x2GB in the slots and not use all 4 slots for the full 8GB, as I reckon this is straining the system... although writing this I've just thought, if I pump 2.2v through the RAM, I wonder????

I've read a lot from people saying that, if you fill all the ram slots, it'll dimish your overclock overclock, so I'll be seeing if this is true tonight... I'll post back fella...

Cheers

Asus boards then to be more stable with 4 sticks or RAM, remember you may need to give your Northbrdge a bit more volts to compensate

Not to ambush this thread, although I'm sure the same applies for original poster, I have my HT Voltage = 1.46v, NB = 1.48v and SB = 1.50v... with my CPU at 1.488v (with Vdroop to 1.456v under load).

Do these voltages seem okay or do I need to up them to see about getting 3.4ghz 100% stable?
 
My VID is 1.3125, which is high and a bit lower than yours.

I'm doing 3.4Ghz fully stable with a slight ram overclock. 378X9

temps don't go above 60C, i have proved stability at 3.55GHz but temps where a bit toasty, but am planing a major overhaul of my cooling. I think there is probably plenty more that your chip can give

IMO i wouldn't borrow the one at work, its a good way to get you in a lot of trouble if somebody fined out.

i must be one off the unlucky ones then got a vid off 1.1625 v but must have a bad ihs because after four coolers and two different cases i still can't get it to idle below high forties on idle and high sixties on load at stock :(

What HSF are you using?
 
My VID is 1.3125 and i run my PC 24/7 at 3.6GHz stable. Idle temps are around 35-37 using Coretemp and around 65 on load. This is with 1.44v CPU z and 1.42v under load.

FSB = 450
Multi = 8
RAM running at 1:1 and 4-4-4-12 (Ballistix) running in all four slots.

Definitely not true. My 1.20VID is a very hot chip, but overclocks really well. I wouldn't trust it to run stock on a Intel Stock Heatsink as a Scythe Mine barely keeps things under 70C.

My theory is:
The lower the VID, the lower volts required to run stock, so, you have more voltage to play with in overclocking hence the 'higher' overclocks.

1.20VID @ 1.4v is an addition of 0.2v.
Add 0.2v to a 1.35VID and you get 1.55v.

Now, If they both overclock to 3.6Ghz at those voltage, you're going to say [email protected] is the better CPU.

Whaddya think?
 
All you people who are running 3.4ghz and 3.6ghz stable, are you running P35/P38 boards? I tried everything last night and can only get Prime95 and OCCT v2.0 stable at 3204mhz, ANYTHING higher and it craps out :confused:

Yes but the same applies to temps as well so you are wrong on that front. You will get variation between chips with different temps for same VID but there is a definite link between voltage and temps.

Take your example. Even if the 1.20VID chip runs hot due to poor ihs at 1.2v it will still run cooler at 1.4v compared with another running at 1.55v

My 1.25v chip runs at 40 degrees under load at 1.2v, 50 degrees at 1.3v and hits mid 60's at 1.55v.

Lower voltage is better for overclocking potential and some people run out of headroom due to poor cooling and find their temps limit their overclock. But that is only cause they are running at such high voltages so hence your second bit is correct - been able to run at 3.4Ghz @ 1.4v is better than 1.55v, not because of the voltage but because of the heat.

In saying all of that, you still get good and bad overclocking chips of the same low VID, it's just that your odds of getting a better overclock increases with a lower VID.

Take a look on the quad core overclocking thread. The lower VID's are in general nearer the top of the charts but some aren't and conversely so high VID chips are up there.

What's your full spec? Have you followed the general overclocking guide and the specific one for your board (if there is one?)

Whats the VID of your cpu?
What's the temps under load you are getting?
