Documenting my new PC (re)build... From Q6600 to i7-3770k

  1. #231


    Hopachi, I left most of the settings in the BIOS at the "default" settings and I simply changed the bclock and multipliers to get to 4.534GHz. The Intel Burn Test ran all cores at 100% utilization and ran 10 iterations and the CPU temp went to 190 degrees F, which is within specs and never crashed. This is what I call a "normal" overclock with no changes to voltage, etc... because I plan to keep the system at these settings for a month before I ratchet them up, a little at a time, to the max settings that are 100% stable, then take it down one "notch" and leave it there.

    When I had the RipJaws RAM installed, I would get random lock-ups in Windows at 4.3GHz, but with the Crucial Ballistix Sport DDR3, I easily got to 4.534, which makes me happy! I put the 16GB of RipJaws in our son's new PC and it's working perfectly in his system.

    Wow.... 190 F ==> That's slightly short of 90 C. That is hot! Luckily you've got a good watercooler to keep things from burning up .

    The upper limit is 220 degrees, so it was still within normal operating range, although I would not be comfortable running the CPU at that temp. The stress test runs all 4 cores (8 threads) at 100% utilization to stress out the CPU. Basically, if the PC passes the stress test, you're good at those settings. Overclocking these components is trivially easy and very fulfilling (at least to me).

    I should also mention that if the CPU were to get past it's normal operating temperature range, it would shut down immediately, preventing any damage from being done. If you bypass the protective measures, you could burn up a CPU, but it would require deliberate effort...

    Running it past 212 with water as cooling could build up too much steam and have a real problem.

    We call it "water cooling" but it's actually polyethylene glycol, so the boiling properties are different. Obviously, I don't want the CPU to reach the upper temperature limit, so I have set the CPU to shutdown immediately once the setpoint has been reached. Even though I'm using liquid cooling, airflow is important to get air through the radiator to cool the liquid, so I'll be experimenting with adding fans for more air through the case. i don't want the PC to sound like a jet taking off, so I'll be carefully adding fans, testing, etc...

    Yes adding polyethylene glycol to water does raise the boiling point.

    The Ivy Bridge just throttles if it get's to hot, that is why you should benchmark the different OC-Settings, because stable doesn't mean that your CPU is not throttling. You usually kill the Ivy Bridge via too high voltages and usually not via temps.

    If your CPU-related Benchmark-Scores go down with a higher OC, then you know that it's throttling. The Sandy Bridge would just shut down or produce a BSOD or die if you turned off the sensors or set-up the max. temp's before getting a warning / auto-shut-down the PC.

    There are some manufacturers that turn some things off (like the VT support) but there are also those that leave them on, so you got one of these then.

    190°F is pretty hot. That can (it's possible) degrade cpu life overtime if it will reach this temp pretty often, otherwise all good. The upper limit of 220°F will reset the PC as we all know it. You can experiment here as you wish since you know what you're doing. Those are all desktops and all is good to go (with easily replaceable parts). For one of my laptops I needed to underclock it a bit (from Windows power management) to get the temp down a notch when I did some intensive rendering on CPU.
