I just got my computer parts. As you can see with a BE CPU I plan to OC the machine once I have it up and running.
But reading the mobo manual I cannot help but get a little disappointed. Gigabyte states that in order to fully utilize the OC potential of a BE CPU or use ACC, I should add a heat sink to the VRM region of the mobo. I would have ordered a better mobo and save myself the hassle of finding a heatsink that fits had I knew about this.
Anyways I will try to OC the thing without the VRM heatsink to see how far I can go without frying the MOBO. The VRM/MOSFET temp should only increase when I increase the CPU voltage right? What temperature is considered safe for the MOSFET?
Pretty good question, for an example if you start with a 95w processor running at 2.8ghz and clock it to 3.4 ghz it may not need any voltage increase. The VRM should not be a concern in this scenario since your board is probobly compatible with the PII 965 which runs at 3.4 and 140w or the newer version which is 125w.
Whats strange is most gigabyte boards at least mine came with a heatsink on the VRM to begin with so why the add one in the manual? The trouble shouldn't start until you begin to exceed the stongest processor level supported by the board. I mounted a small fan on one of the case slot covers and positioned and secured it above the VRM to keep it cooler just for longevity. I'm afraid to quote what I remember being the safe limit and will watch for someone to post who's sure on what that temperature is. No problems good luck
Yup, basically if you don't go over the vcore used for the 965 140W version you'll be fine . As for ACC, it doesn't really help in overclocking Phenom II CPUs, but is useful if you're trying to unlock the extra cores .
