Gigabyte 965P has automatic overclocking? C.I.A2???

audiobahn1000 · 11-27-2006, 04:31 AM

I was getting ready to overclock my CPU when I noticed something in the BIOS. My Gigabyte has a feature called CIA2 or CPU Intelligent Accelerator 2. In the manual it says there are 5 different levels. It also says what each level does. IT says:

Level 1: Automatically increase CPU frequency 5%,7% by CPU loading.

as you move up to each level the frequency increases untill you get to level 5 where it say "Automatically increase CPU frequency 17%,19% by CPU loading".

Well what is this feature? Is it an automatic overclock? If so does it adjust the vcore and all that to keep your system stable? Does it overclock the RAM and GPU too? Anyone know?

Yes, it's automagic overclocking. It overclocks the RAM because it adjusts the FSB, video should be unaffected. I don't think it adjusts vcore, it shouldn't increase it so much that it is necessary.

So if I choose level 5 (the 17%,19% overclocked) option I still wont be getting everything I can get from this computer? As in thats not overclocked enough?

Well, you decide what is enough. It is your hardware so however far you want to push it is up to you. E6400s have been known to run at upwards of 400MHz FSB though.

3.2 ghz. with the stock cooler?

Not necessarily on stock cooling. If you were to go that far I'd get an aftermarket cooler for the CPU and at least a fan on the northbridge, the heatsink they have on the 965s is on the small side.

Yup. You can do that. I have my E6300 running @ 3.2 Ghz at the minute with the stock cooler.

However, Cromewell is definately right about Northbridge cooling. I have placed an 80mm fan on top of my graphics card with little blue tac feet, so it's blowing cool air right over it.

If you want help for which to overclock, just ask. You are going to want to raise the MCH voltage by +.1v to get overclocks it excess of ~2.8 Ghz.

P.S. Make sure you update to the latest BIOS too - F7 is the current one. F8 will be released in the next week or two I think. http://tw.giga-byte.com/Support/Moth...ProductID=2314

What is MCH? Are you refering to the vcore? Did you use the CIA2 to OC? Because I am thinking of maxing out the CIA2 first and seeing how that goes.

**Cromewell** · 11-27-2006, 09:30 AM

MCH is the memory controller hub aka north bridge. MCH has a voltage setting in the MIB section (ctrl f1 unlock needed).

No I did not use C.I.A.2, since I don't trust it with my hardware. I would rather overclock everything myself, since then I know what it being overclocked, and by how much.
