p8z68v pro/gen3 - i7-2600k Questions

post #1 of 13
Thread Starter 
Hey overclockers!

I've just finished putting some clocks on my p8z68z pro/gen3 motherboard and i7-2600k.
However, in CPU-Z and my ASUS monitoring programs that my speeds are still at the 1.6ghz and jump to my new clock (4.7ghz) on load.

It had been a looong time since I overclocked, and to be honestly and still getting used to a lot of the new features the EFI bios has to offer. So I wanted to know if this jump (I'm assuming its the whole "turbo" thing) will cause me any problems.

What I mean by this is: will I not be getting the full performance of my overclocks? I do a lot of programming, but also some gaming. I don't need these clocks for work of course, so its really just for the gaming side. If what I have right now keeps the speed low when I don't need it, and saves me power and energy I'd love that. But I also want to make sure I am getting the full performance of my CPU when I am in gaming applications, or using heavy programs.

Thank you for your time, and hopefully I can get this figured out! As you can probably tell I'm not the most experienced XD but I try.

If I can get this cleared up, I might have a few more questions, but this is what is bothering me the most right now.

Thanks again!

You either have one of the C power savings states or EIST enabled in the BIOS. When not under load, with any of these power savings modes enabled, the processor will drop its frequency (and also voltage if you are using offset voltage in BIOS) down to its lowest level of 1600 MHz in order to reduce power consumption. This is good, but depending on which power savings mode is enabled, can cause lags in performance under some applications or circumstances.

The higher C-states (C3 and C6) take longer to come out of than does C1E or EIST. Also, enabling C1E can affect SSD performance. Personally I have only EIST enabled and, in Windows power management, have the minimum processor state set so that instead of dropping down to 1.6 GHz, I only drop to 2.2 GHz.

There is no impact on performance with EIST and C1E. It's imperceptibly responsive from idle to load.

Thanks for the replies GeneO and samwiches!

This puts me at ease. I did a bit more stress testing and tried the clocks out in some games, and the clocks seem to be good. I seem to remember turning off C3 C6 and C1E, but I guess I still left something on.

I'm a little sad about my temps, during prime95 it was going between 69-76 C and I have a 212+ and antec 902...I probably didn't do the best job applying my thermal compound frown.gif At idle and in games everything seems to be good so far however.

Thanks again for the replies!

No prob, easy thread.

You can try a reseat to find out if your temps are normal, but your voltage is the biggest factor. Past ~1.40v you start to see mid/low-end coolers fall behind in performance.

So a reset clocks, run prime, monitor temps kinda thing? Under load my voltage was 1.376v as displayed by CPU-Z. I didn't think that was too bad, but I could be very worng smile.gif

There is if you have an SSD and use C1E

Case fan configuration can make a big difference too. But that is fair temps for the 212+ and 4.7 GHz at that voltage on that processor. The temps start ratcheting up beyond 4.5 GHz with the 212+ (at least for me).

I think you're confusing C1E with C3 and C6.

No I am not confused - I know quite well the difference between these states and what they do.

C1E can reduce the performance of an SSD. It did mine and others (do a google search).
