Overclocking Asrock P43DE and Xeon X5460?
Overclocking Asrock P43DE and Xeon X5460?
I noticed many YouTube videos showing how to increase the clock speed of an x5460 to 4GHz or 4.26GHz, but yours only reaches up to 3.5GHz and then crashes. What could be the issue?
Not enough voltage or insufficient cooling. At 4.0GHz a 45nm C2Q uses 200w and at 4.26GHz over 260w, which you're trying to power with just a 4-phase VRM that might not be enough for the job. Exceeding the never-exceed voltage of 1.45v is necessary for stability at these frequencies but will reduce the lifespan of your old hardware in exchange for showing off on YouTube. Purchasing the kind of heavy cooling needed for those speeds on an older CPU isn't feasible, as it would cost more than a newer i3 that would work just as well at 35w.
1) Overclocking is like a silicon lottery. Some devices will overclock intensely, others won't, but all comply with the official requirements.
2) Trusting everything you see on YouTube can be risky.
