If you have a non-K chip, the best you can overclock is 4 multipliers. For that you can just leave the voltage in Auto, should be able to get that speed without the voltage getting out of control (Auto sometimes sets really high voltages when you get above 4.2 or so).

So work called, had me going in later this morning, figured I'd play a bit with my processor's settings to see what I can find.

Sadly, it does look like I'm locked, in the asrock z77 extreme4 it only lets me set a max multiplier of 43, anything higher it defaults down to that.

Started at 1.2V and running prime95 as we speak (will run a longer test after work, don't want to run it while I'm not here to watch for shenanigans), but for some reason, on both speccy and cpuz, it's showing the multiplier locked at x41...whyyyyy?

Posted a screen shot of my cpuZ and speccy in case someone sees something fishy, those temps are with the prime95 running as well, in case you were curious about them.

On the Core i7-3770, the maximum overclock multiplier is 43 but this is only available when a single core of your CPU is active. When all 4 cores are active, the maximum multiplier is only 41. It looks like your CPU is running exactly as Intel intended. You can probably drop your core voltage down another 0.1 volts and still be stable at that speed. The fully adjustable Core i7-3770K is a much better choice for overclocking. The regular 3770 is a better choice if you need VT-d virtulization support since the K series does not have that feature.

Awww, sad face, well, at least I have a 4.1GHz processor now though biggrin.gif

Gonna restart my computer after the third pass of this test, if it's still stable I'll drop the voltage another .1 as you suggest, see what happens.

Thanks everyone for the assistance! I really do appreciate it!

As a side note, during the 8k test seemed to put the most stress on it, but the processor only got to about 62-65C, looks like the kuhler 620 works nicely biggrin.gif

Thanks again!

Having an issue now. Dropped the voltage to 1.1 and it blue screened on startup...trying to get back into the uefi to change it back and its freezing before i can adjust it...and ideas?

Crisis averted! Found out how the cmos jumper on this bloody mobo worked (first time with a mobo that has one), had to reset all my ram values though, but at least i know at 4.1 my cpu needs at least 1.2 v to run!

Have a look on your motherboard for a reset CMOS button to return your board to its default settings. You might have to use a jumper and jump 2 pins for a few seconds to reset the CMOS.

So, an update as I was asked to give one. Did my stress testing yesterday/last night...and I wanted to play a game, so I figured I'd pause the the test to do some gaming....well...4 hours of gaming later, I turn off the game, and see my cpu temps are still in the 60s...I'm a bit worried because before I started stress testing they were in the 30-40s idling...poking at my active programs...it turned out I forgot to shut off prime95!!

Needless to say...running games while stress testing, while not the best idea, I think it's safe to say this processor is good and rather happy at 1.2V and 4.1GHz.

I actually ordered a samsung 256GB SSD and a 1TB 6GB/s 64MB cache western digital last night....so once those arrive, I'm reasonably certain this computer will be a medium sized beast biggrin.gif

To explain current build for those just joining:

16GB g.skill trident x ddr3 ram (7-8-8-24-2T) 2x8GB sticks
i7-3770 @4.1GHz with an Antec Kuhler 620 closed look liquid cooling system
nvidia geforce GTX 660Ti (I'm not comfortable OCing this big boy just yet ~-^ )

all inside the Cooler Master HAF X case with 4 massive 200 mm fans and wheels, I even turned the psu upside down so the exhaust would blow out the bottom of the machine (there are air vents right below the psu on this thing), so that hot air would stay outside.

Thanks again though for everyone's assistance with my first actual OC experience! Rest assured after I've replaced the kidney I used to pay for this I will probably be doing more in the future...stupid OCing...way too addictive >->

You might want to change the orientation of the PSU again if your goal was to remove hot air. That fan is the intake. The exhaust goes out the back. If you want it to act as an additional exhaust then you should have the fan facing upwards towards the CPU.

Good quality PSUs can easily handle having warmer air come through them and exhausting out the back but if you find the fans spin up appreciably more and make more noise then I would flip back over and face the bottom.
