Max Voltage for i5 3450 4.0Ghz - Page 2

3450K doesn't exist.

All of the posts in this thread have to be read in order to fully understand what you have to do.

Ok so by using Easy Tune 6 on my Gigabyte Sniper m3 board i was able to run Autotune which gave me 4.0Ghz! Or i could run the Quick Boost which gives me a choice of 3.43 Ghz BCLK 101 Mhz or 3.57 Ghz BCLK 102 Mhz or 3.81 Ghz BCLK 103 Mhz. So simple and easy. The changes were confirmed using the Intel Turbo Boost Monitor. For now im just selecting the 3.43Mhz settting.

I have read somewhere that some do not l ike the way Quick Boost changes the CPU voltage to suit. So maybe a fixed voltage setting would be safer? Not sure..any thoughts?

Thanks for your help

It would be better to use offset voltage..set it..reboot..see what it says in BIOS..rinse..repeat..
probably low 1.2-ish should be enough..

I don't know, but most of us here on OCN strongly prefer doing all of the overclocking directly in the BIOS instead of using any software. Although, we prefer to have full control instead of allowing some software to do some of the work for us.

It's like the old saying goes, "If you want something done right, then you have to do it yourself"

I got this far using only Gigabyte AutoTune............

Ok I was going to start a new thread but this one seems pretty related to my own issue here.

I've just recently upgraded from a P6T 1366 i7 920 to an ASrock 1155 ivy 3450.

I'm trying to experiment with overclocking and can already tell it's much different comparead to the bloomfield i7...
I'm aware I bought a "locked" CPU but my understanding WAS that that simply means that the multiplier maxes out at 37, and/or I'm able to adjust the blck frequency. That doesn't seem to be quite the case though...

I'm experienced at doing-it-myself overclocking (I put the 2.66GHz i7 920 up to 4.4GHz stable) by setting some voltages, and adjusting blck frequency. I've tried doing the same here and it just doesn't work.

As far as I can see, not only is the multiplier locked, but also the blck frequency? I've tried setting the multiplier to 31 and moving the blck up, but can only get to about an added 6 MHz and then it won't boot (have to reset cmos)... That obviously doesn't do much of an overclock at all.

I'm confused about the multiplier, because usually after you do an overclock, you can right click on Computer, go to Properties, and it will show your overclocked frequency. I also have CPUz installed to look at it too.

When I turn off the turbo and adjust the multiplier to 35 and blck to 100 for example, CPUz and Windows shows the CPU at 3.1GHz still.
The overclocking/monitoring utlitiy that came with the motherboard, ASRock eXtreme tuner, shows the frequency at 3.7GHz, so I'm having issues with which to believe.
Also when I try to adjust the BLCK frequency and then boot up and look at ASRock tuner, it shows that the blck is still 100. Anyone know what is truely is for one? Also the BIOS does let me select the multiplier to 39, but again ASrock tuner only shows it to 37.

For 2, if I'm adjusting the settings in the BIOS, and looking at it under CPUz or windows and it's still showing 3.1GHz with a multiplier set to 37 and a blck set to 105, am I truely overclocked or is my BIOS not setting the overclock or what...

Either way I am disappointed in this "unlocked" "locked" crap... I bought the 3450 because of budget reasons and thinking I can overclock this thing "old school" but apparently Intel now tells us we have to spent more money just to do what we want with it... I was hoping to bump this up to 4.5GHz using blck but obviously that isn't going to happen if it only lets me set the blck to around 105/106...



*************EDIT**************
CPUz wasn't working properly for some reason. I uninstalled it and reinstalled it and now it is showing the overclock. Here's the issue. You CAN set the multiplier to 39 to all cores.
You CAN'T disable Turbo when you are doing that to all cores (kind of annoying but technically is better for your CPU so you don't have a constant overclock).
When I set my multiplier to 39, and upped the BLCK by ONE MHz (101) I booted up and blue screened right away. Absolute CRAP.
It seems you can either up the multiplier to 39 and 100 MHz, or keep it at 31 and up the BLCK to 105ish (pointless). You don't have to adjust any voltages, it will auto adjust depending on load. This is all related to it being a "locked" CPU. Such bull. I'll have to be happy with a 3.9GHz overclock. I shouldn't be complaining because that's plenty fast and honestly... you aren't going to *see* any performance increase going from there up to 4.4 or something. But it is still irritating you have to spend $60 more to have an "unlocked" CPU. Guess that's one of the plusses that AMD has over Intel... still don't buy AMD, though.

Have you tried downloading from Intel the Intel(R) Turbo Boost Technology Monitor 2.6 ? i would trust this..................

No I haven't, but CPUz has always been trusted and is working fine now. I would say though that the ASRock eXtreme Tuner is a crappy program. It monitors the CPU temps just fine, but not the bios overclock. It's also a program designed to "overclock your hardware from desktop" which has never been 100% stable or "true-overclocking" with any vendor. BIOS or nothing. Software does not do the trick. I'm just sticking with the Turbo boost. When you are at idle at desktop, the CPU clocks down to 1.6GHz. When at load, it goes up to 3.9GHz. I'll just be content with this. I do think the downclocking feature is pretty cool. Ideally it'll make your CPU last longer rather than having it at a constant high speed.

My i7 920 lasted almost 5 years @ 4.4GHz. It just started having issues a few weeks ago.

Yes, I agree. I like the turbo boost. I see no point running a CPU at 100% all the time.
