First time overclocking, is this correct? - Page 2

post #11 of 17
You can leave all the power saving on - it normally doesn't interfere with overclocking for these chips. If you run into trouble then you can try disabling them as part of your troubleshooting. Depending on the motherboard and BIOS, Auto for the settings may or may not be enabled during overclocking - some boards automatically disable some of them (normally C3 and C6) when overclocked. You can try setting them manually to Enabled if you want.

It is also normal for the CPU cores to clock up and down while the system is lightly loaded - background tasks are what are causing that. If the CPU is going straight from 1.6 to 4.5 that may indicate that C3 and C6 are now disabled - try enabling them and see if the CPU hits intermediate frequencies in the idle situation (so from 1.6 to 2.3 to 3.4 rather than straight from 1.6 to 4.5). Or you can just leave it alone - it sounds like it is working fine as it is.

Oh yeah you're right my Asus board disables those on automatic. I turned C3 and C6 on manually and now it's doing exactly what you said. I'll just leave that on auto and let my board do what it wants with it.

I also tested BF3 and for that game the CPU is staying at 4.5GHz without downclocking.

So I guess my last thought is do all those settings look right for you? I didn't do anything unneeded or forgot something right?

Also, my voltages should be okay right? If I can run Prime95 for 6 hours on Small FTP and it passes then it's not overvolting or undervolting what's needed correct? Since you said the VDroop isn't bad and at 1.320 volts it's running prime for hours I'm assuming it should be a-okay.

PS: Just noticed CPU-Z is showing my memory at only 667MHz but it's supposed to be at 1333MHz.

667Mhz is DDR3-1333. The 1333 is MT/s or "transfers" as DDR is double pumped, it transfers twice per clock cycle. That is exactly what it should be for 1333 speeds.

Everything looks good. The only thing you can think about is changing from a fixed voltage (which the chip will run all the time, even at idle) to an offset, which will allow the chip to downvolt at idle. If you want to change, there's a little trial and error involved. In offset mode, the board figures out the Vcore by taking the Vid requested by the chip and then adding the offset you specify - so if the chip has a Vid of 1.30 at 4.5, you'd need an offset of +0.05 to get the correct Vcore. So to set it up, you need to set offset mode, then set an offset (something like +0.05 to start), and then see what voltage that results in at load. Then you need to go back and adjust the offset to get the final voltage you are looking for (so the same as your stable manual voltage).

But RealTemp says my VID should be 1.4 and from what I read that's an awful lot for a 4.5GHz overclock. Even my motherboard shows that number as a red color.

My temps would also rise.

At the moment I'm getting...

66C
72C
67C
68C

Core 1 and 2 go to about 71 and 75 very briefly but go back down to the 60's after a few minutes. This is with a Small FTP Prime 95 benchmark.

Do you think I should run it at 1.4?

If you're stable at a lower number, don't bother increasing it. VID != vCore effective. Take what you can get.

No, if you decide to use an offset, you just tweak the number in the offset field so the resulting Vcore is the same as you had set manually. You can enter a negative number there, so if the Vid really is 1.4 and you only need 1.35V, then you would set a -0.05 offset. The Vid you see in CoreTemp or whatever doesn't really matter, just play with the offset to get the desired Vcore.
