3570K and P8Z77-V LX problem

Hello again all,

So I am new to overclocking, and bought this mobo/cpu setup because of ASUS' solid reputation for OC-friendly boards. I can't get the system to OC over stock speed manually. I'm having a few issues I hope someone can shed some light on for me.

Issue 1: Using a basic bios setup, that is, disabling EIST and Turbo and setting ratio manually, the chip defaults back to 1.6 gHz at idle and 3.6 gHz under load. The bios will even read "Target CPU speed - 3800 mHz", and when I reboot to bios, it sits at 3.4 gHz. When I boot to Windows, CPU-Z reads me at the default settings I mentioned above. It even does this if I disable all c-states, bump up LLC a bit, manually input both core voltage and base clock as 1.1 volts and 100 mHz, respectively.

Issue 2: I updated the bios, and when I move to the submenu "CPU power configuration" and disable both EIST and Turbo, it gets weird. I do this, and then enter a manual CPU ratio. When I type in "38" and hit enter (for 100 mHz x 38 = 3.8 gHz), the bios turns Turbo back on, and greys it out, making it non-selectable. And leaving it that way and doing all the lock and disable tweaks as above yields the same result. It boots to Windows and bios and both register the cpu at 3.6 or 1.6 gHz, depending on load.

I don't get it. Is it possible that I have a botched board? Or is there a setting I am not disabling? I have read many threads about people OCing this same setup, and no one seems to have trouble getting this little i5 up to 4 gHz+.

Well I turned the turbo on, and set a CPU ratio of 38 (100 mHz x 38 = 3.8 gHz), and it clocks at 3.4 gHz in 10 runs of Intel Burn Test.

Also, it sustained 4.4 gHz using the ASUS bios auto-overclock utility at 1.18 volts. I have read that the auto-OC suites are not to be trusted, so after a test of BF3 for 25 minutes, I hit 47 degrees celcius, and it was running good, though I saw spikes in core voltage I didnt really like, considering what it ran at normally, so I turned it back to stock (doesn't manually overclock).

OK, so now my cpu will not climb at all above stock core speed, even with speedstep and turbo on, even running 100% load under intel burn test. I defaulted my mobo back to stock bios settings, and it doesn't do anything but 3.4 gHz even though turbo boost is supposed to kick it up to 3.8 as per the bios.

I don't know if I messed it up or not, but I've ran out of ideas, and can't get results. Anyone else have this problem?

Thanks Big Lig, your bios shots were helpful. I know now that I'm correctly setting the right things to manual and such, I just have different values and I don't disable PLL overvolt cause I can't even get it to 3.8 and have it stay there.

What I mean by that is: I set my bios up with nearly everything you show as turned to manual, as in, eist is disabled and turbo locked on enable, and I have my core voltage locked at 1.15 volts, all c-states on auto, baseclock set on manual to 100 mHz, and the multiplier set to 38 for 38 x 100 = 3.8 gHz. When I boot, I open CPU-Z, RealTemp, and Intel Burn Test, and for the first 20 seconds of having them open the cpu speed reads in both CPU-Z and RealTemp as 3800 mHz on a 38x multi. It runs the first iteration of Intel Burn Test at 53+ gflops, and then after the 20 seconds is up, the processor (temps stay low, I'm sure to watch) underclocks and locks to 34 x 100 = 3.4 gHz, then runs at about 48-49 gflops. It never goes back up to 3.8 gHz even if I run Burn Test with Battlefield 3 running in the background and browser windows open, and all kinds of crap.

I'll try to get camera shots of my bios and post them up for you to see, AND see if I can get a pic of it clocked to 3.8 momentarily... not that it'd do any good.

Not yet, wanted to see if I could get the ASUS working for OC, because if I put in the Gigabyte, I have to reformat, and that's a pain in the rumpus.

Ah. No worries Big, I'll disable all the c-states and play with it... I only have 4 options to disable: C1E, C3, C6, and another I'm blanking on it's name... But I'll disable them anyway, and run it out.

-Donny

Well... turns out they've been disabled this whole time. So no change there, unless I'm supposed to leave one of them on.
