The Q6600 can be overclocked using the stock Intel cooler from its previous generation.
The Q6600 can be overclocked using the stock Intel cooler from its previous generation.
I'm just excited because I'm about to receive a Q6600 for this old machine that I plan to overclock.
I know it works well with this setup, but let's start with the system.
Mobo: Asus P5K
RAM: 4x2gb at 800mhz
GPU: GT 730 GDDR5 OC clocked at 1006, reached 1100Mhz.
400W PSU
Before you ask about the power supply, I've already checked it—I bought the G0 model, which should be fine. The calculator suggested around 370W (with CPU at 3.0Ghz), but with what I have now.
For context, I managed to get my E6750 up to 3Ghz without exceeding 69°C after a 20-minute stress test; it stayed under 72°C. I'm aiming for the Q6600 to hit 3Ghz, possibly even 2.8Ghz.
The C2D scores 130 at stock and 150 at 3Ghz on Cinebench R15, so it's performing well.

Before you ask me to check the PSU specs, I already did. I bought the G0 version so it shouldn't be an issue. The calculator suggested 370W (with CPU at 3.0Ghz) given all my components.
For context, I got my E6750 up to 3Ghz with a max temperature of 69°C after stressing it for 20 minutes—max was 72°C, so I could push even higher. Now I'm thinking about bringing the Q6600 up to 3Ghz if possible.
Mine operates at 3.2Ghz @ 3.5 volts using the standard cooler.
Jackbutler:
It runs at 3.2Ghz @ 3.5 volts with stock cooler. That's okay. How are the temperatures looking? The site mentions the G0 version can handle up to 71 degrees.
theyeti87 shared their experience with upgrading their Q6600 to 3.2Ghz. They noted the voltage wasn't confirmed, but the unit performed well under stress tests, reaching temperatures around 89-91°C. They found it quite hot and mentioned it would be uncomfortable at 90°C. They also praised the Q6600's OC performance compared to the E6750.

Before you ask me to check the power supply requirements, I already did. I purchased the G0 model so it shouldn't be an issue. The calculator suggested a 370W unit (with CPU at 3.0Ghz) based on my current setup.
For context, I achieved 3Ghz with my E6750, keeping temperatures under 69°C after stressing for 20 minutes. The max was 72°C, so I could push further. I'm aiming for the Q6600 at around 3Ghz, possibly even 2.8Ghz.
The C2D scores 130 stock and 150 on 3Ghz in Cinebench R15, which confirms it's functional.
Just switch the FSB from 266 to 333Mhz and keep the voltage at 1.3. My G0 reached 3Ghz with stock voltage (manually set to 1.3V). You can go higher with a better cooler. Push 1.3-1.35 might get you to 3.2, but not much beyond that, even for the G0. At 3Ghz, temps shouldn't exceed 80°C unless you increase the FSB.
By the way, stress testing for 20 minutes doesn't guarantee stability. You should run longer tests using tools like Prime95 with small FFTs. I usually run for an hour during setup and basic OC testing, then overnight after I've locked in the changes to confirm it's stable.
Regarding voltage, I'm just starting out with CPU overclocking and feel a bit confused. I haven't adjusted anything on my current CPU except changing the FSB from 333 to 380. Since my BIOS is set to x8, it seems like that's the highest it can go.
I'm just starting out with CPU overclocking and feel a bit lost about voltages. I haven't adjusted anything on my current CPU except changing the FSB from 333 to 380. My BIOS is set to x8, which seems to be the highest it can go. It's strange since it should support a 9x multiplier. Running core temp will show your VID, which indicates the maximum voltage needed for proper operation. For my chip, it was 1.3v (relatively high for a G0), so I should manually set it in the BIOS to that value. If you can, take a screenshot of your BIOS settings and we can guide you further. You only need to adjust the voltage accordingly and increase the FSB if needed. If it crashes, you can gradually increase the Vcore until you reach Windows and can properly stress-test it for stability. Others have achieved 3.2 with an 8x multiplier but require a higher FSB (400MHz). Some LGA775 boards have a memory hole that might prevent proper booting. Consider trying the 8x multi with a 400MHz FSB to see what works best. You might also need to raise the SOC voltage since you're stressing the memory subsystem, which could require another voltage adjustment. Updating your BIOS would likely help improve the overclock potential and fix the missing default 9x multiplier.

I also managed to get my old Q6600 up to 3.2Ghz, though I'm not sure about the voltage. It held stable during the stress test, but it was around 89-91C. That's really hot for my comfort. It's super intense. I wouldn't want it at 90C at all. From what I've heard, the Q6600 does great in overclocking. Better than the E6750, so yeah.
That stock cooler definitely made a difference.
