Overclocking Trouble

rdoxenham · 4 Nov 2011 at 12:09

Hi All,

I'm new to the world of Sandybridge overclocking but have successfully managed to overclock my i7 2600K to 4.5GHz @ 1.35v. Have run prime95 and Intel Burn Test and it's now stable at this speed/voltage. My max temperatures recorded were 68-69 degrees so I'm relatively happy.

My system spec is as follows- i7 2600K, Asus P8Z68 B3, 16GB 1600MHz Corsair Vengeance, and a Corsair H80 waterblock.

However, I'd like to push it a bit harder rather than just 4.5GHz, I tried to go up to 4.6 but still wasn't stable at 1.37v. What would people recommend here? Going higher with the voltage? Disabling hyper-threading?

Any input would be welcome. Thanks a lot.
Rhys

try upping voltage a bit

What's the 'safe' limit? I know that increasing the voltage can harm a CPU over time, but I didn't want to push it too hard considering I've only had it for a few days :-)

***OVERCLOCKING GUIDELINES***

- Do not exceed 1.425-1.450v core voltage, doing so could limit lifespan of the CPU
- Do not overclock with BCLK, again doing so could limit lifespan of the CPU
- Recommended memory voltage is 1.50v, so make sure to run your memory at 1.50v, higher than 1.60v could limit lifespan of the CPU
- These recommendations come from OcUK and Intel, your warranty is un-affected but we highly recommend you adhere to the above to make sure your CPU lifespan is un-affected
- All Sandybridge CPU's worldwide should be run at the above or lower voltages, no higher!
