asus P8Z68-V pro and Intel 2600 oc went bad or something

[etrin]

I got this last year and was thinking of oc etc.
Well the first thing I did was turn off the onboard sound and clicked on the oc tuner in the bios.
Well after seeing this go crazy on several previous builds (mainly setting voltage TOO high)
I was shocked to see 4400 ghz and at idle it was running (I think) at 1.6Ghz
Wow and less than 60C running all out with sli video cards.
I was happy to say the least.
Well it has run like this for a year and again I am happy.

well we had a power outage here last weekend.
On reboot it said overclock settings are not valid.
I went into the bios and I thought I did the exact same settings and hit the oc tuner button.
after a reboot it is running at 3411 34x103 all the time.
wait thats just stock settings.

I have tried everything I can think of and can't figure out why it won't change.

anyone got any ideas?

I am stumped.

Have you tried overclocking manually to the old settings? I've overclocked probably 10 2500k/2600k systems since launch and I'm pretty sure they all were able to hit 4.4 GHz

Is this a 2600 or 2600k?

 

[etrin]

its a 2600K.

I just can't figure out why it won't throttle.
it is now running at 3411 all the time.

You have multiple factors here
A power outage has a big surge when it comes back on

Then you used OC Tuner which is a system killer
It starts out a ridiculous high O/C like 1.5V+ on CPU and works its way down
I am terrified to click that option by mistake
Why they still put that horrible thing even now on latest mobo is beyond me
If you want an auto overclock, then use the TPU switch and reboot coupla times to bios - usually gives 4.4GHz
Always use XMP profile for RAM (AI Overclock in bios) which sets 100.0 BCLK
And turn off Intel Turbo in bios - if you are overclocking you dont need it and it will interfere with a manual O/C setting.
You are now at 3300 base frequency - 33 X 103.3 BCLK or 3411
100.3 - 103.3 is spread spectrum values, only needed if you live next to a cell tower. Its not an "extra" overclock.

Clearly the power outage reset your bios to defaults, and you should have saved all your bios pages before with bios screenshots to FAT32 stick (F11)

The first thing to try is a full cmos reset
Shut down PC, turn PSU rocker to "0", push in case "ON" button till lights go out
Unplug PSU, take out battery, let it sit for at least an hour

The good thing is that your PC still boots O.K.
You are very lucky

Fixing throttling is no sweat (EIST CIE C3 C6 settings and Win 7 power/advanced/proccessor setting/min max), but at this point you may need a new bios chip from ASUS $22 - $15 plus $7 ship from online E-Store, depending on cmos reset outcome.

You may have corrupted bios with crazy ASUS overclock or power fail, or you may have just screwed up re-entering bios options

thank you for the info. I have some work and testing to do.
I manually set it to 4400 and that was not problem.
Then I ran occt to give it a torture test and it ran fine so it seems that the mb and cpu are ok.
And I hate to admit it but I did NOT capture any bios pages...AND now I am paying for it.
When I first set this thing up like I said I was shocked to see 1.16 V at 4.3GHz and it throttled down at idle to 1.6
About a month later a friend was looking at my system and booted up cpu-z with some stuff running ant it was at 4.5GHz. Say what I didn't change anything. I then checked it and the voltage and temps were the same. So I was really impressed with the setup at that time.

one other question what setting in bios turns on throttling?

 

[DigitalWolf]

There should be a page (likely somewhere under cpu settings) that mention eist and various c states.

*edit* I guess I should add if you want the various power saving states active etc they should be enabled. If they are enabled in bios there is also a place in Windows power settings that can disable it. So IF they are enabled in bios and its still not stepping down in speed.. in advance power options you'll see a processor setting that has minimum/maxium percentages. If the minimum somehow gets set to say 100% it won't throttle regardless of bios setting. <- at least in my experience.

Oh, thats dif.
Your only prob is no speed stepping

and a reboot to take effect

Edit:
fwiw you keep running OCCT and other torture testers and one day somethin in you system will just die

I looked in the control panel and it was set to performance.
I changed it like you showed and it now idles correctly.

Thanks everyone I now have my system back the way it was.
Man power outages cause a mess LOL

I was only using OCCT to give it a load and drop it back to idle to see if it was throttling.
I was impressed with the latest version a lot more info than the old ones.
