Need some to overclock me

wondergamer · 26 Jul 2009 at 00:12

Hey guys

i need some help with overclocking my machine

Specs

Q6600 (b3) stepping, 2.4ghz (stock) (((Stock cooler))) Currently @ 2.7 ghz
4 Gb of ram , 2x ddr800 kingston and 2x ddr800 Pny (Dual Channeled)
Asus p5b (needs updating)
Evga 9800 gtx
650 w coolermaster

As you can see i have already clocked the machine at 2.7ghz and am running stable with cores at around 44,42,41,43 idle 49,48,50,46 under load. all i have done is raided the FSB up to 299.

My vcore and most of the other options are set to auto such as the ram timing frequencies which i have no idea of. my problem is that i am trying to acheive 3.0ghz on the stock intel cooler is this possible as when i have tried clocking it to that speed before it crashes on boot up and i have to remove power cabels and reset. Im pretty sure it is another setting causing this possibly the ram? or maybe i have just hit my limit :mad:

If anyone could kindly help on the situation it would be more than appreciated

Hi Wondergamer,

My guess is you need to up the core voltage as that looks to be running at stock volts. My Q6600 is at about 1.42v in bios in my ABit IP35 Mboard, which shows as 1.352v under load in cpuz. This is running at 3.3Ghz, 367x9 and is prime stable (has run pretty stable at 3.4Ghz but not 100%).

I am running a Thermalright ultra 120 extreme cooler so thats making sure there aren't any heat issues.

By the sound of your max temps, I'd say you've got a bit of leeway to up the voltage a little even on the stock cooler. Just be very careful to monitor your temperatures, I'd suggest max stress test temps must be below 65 degrees. Theoretically these CPUs are rated to a much higher temp, but I get jumpy once you hit 60 and above.

Also be aware that mines a G0 stepping which will clock better than yours, so don't expect to get as high as mine.

thanks for the quick response Evil-I

yer i know i need to upgrade to a G0 stepping soon. is it safe to up the vcore and what would you suggest i try? , i would like to hit 3.0ghz on this cpu and would have no need to overclock further than that, nor would i want to.

i understand what you mean about risks but i think the blowout for my b3 is 85 degrees as it is the Tj max but still i rely to heavily on my comp so that would be a risk

I am also thinking of getting the Zalman CNPS7500-ALCU LED Socket next week?

i d say on the q6600 that 1.5v is the safe max vcore but you will be stopped by temperature long before you get stopped by voltage, also what are our load temps

wondergamer · 26 Jul 2009 at 15:49

well my temps under load are usually 52,53,53,49

Most Q6600's I've had my hands on will do 3GHz on stock volts but then need a hefty increase to get them to 3.3GHz and a further hefty increase to get to 3.6GHz.

Your 1.2875V looks extremely low to me for a B3 (my early G0's were all at least 1.32V) and for a B3 it seems to run very cool.

If you want a big overclock on a Q6600 then you'll need at least 1.4V and that will need good cooling.

Try setting 1.4V in the BIOS and dial in a healthy FSB (try 333MHz) and it'll most likely boot if the RAM divider is correct. Then try 366MHz and see if that's stable.

You do need to be brave with the voltages though!

WJA96 thanks for your response buddy, i completly understand but if i hit 1.4v in the bios with a fsb of 333 and correct ram divider (could some1 explain this easily please) will this kill my comp ??

there is no gurantee but it is extremely unlikely

Hi Wondergamer,

Just lapped my thermalright heatsink and cpu to improve my temperatures and had another crack at overclocking my q6600 go.

Now running prime stable at 3.5Ghz (390 x 9) although this is with a fairly hefy amount of volts dialed in. Showing 1.5v in Bios on my Abit IP35 which appears as about 1.4v under cpuz in windows.

Max core temperature under load is 68 degrees.

I must say that I'm slightly concerned running it with the volts as 1.5, but theoretically as long as the temperatures okay I shouldn't have any issues.

Fingers crossed ;-)
