Hello Gurus :)

I'm tinkering with over clocking on my lovely new build;

gigabyte z77n-wifi
8gb crucial ballistix sport
i5-3570k
Hyper 212 Evo Cooler

But I cant select an FSB higher than 100mhz in the BIOS. When set to AUTO, it gives me 100mhz, when I go to change it, it only offers me 80mhz or lower :(

In the Bios i can change the Multipliers fine and have got up to 4.22mhz using a multi of 42! I read on these forums that i should disable any "turbo boost" in the bios which I did - still no dice!

Here's the weird part - in windows i load up Easy Tune 6 and i'm able to tweak the FSB and multipliers - using this method I'm currently getting;

4,220mhz with x41 and 102.9mhz FSB

On full load temps are circling at 68C/69C

-----------------------------
so;

    I read it is better to configure the BIOS for overclocking rather than software - how can i increase FSB past 100mhz in bios?


    My 1600mhz ram is currently running at 1854mhz - this is probably due to the change in FSB - is this a good thing? I read that I higher FSB and equivalent ram can be good for performance (gaming)


Thanks guys - would love your input and/or other peoples results with this combination of mobo/cpu


Best wishes,
Barry

Intel cpus don't like having their fsb raised much over 100mhz. I wouldn't even bother. When you overclock the fsb, you are overclocking the entire system- RAM, igpu, PCI, sata, and USB ports, etc...

Just used the unlocked multi to overclock. It leaves everything else alone.

ohh really? ok

But why with the gigabyte easy tune software can I overclock the FSB but not in the gigabyte bios?

I just ask because I have been reading some stuff that says small increases in FSB is better than an outright massive multiplier

Two words of advice:

1) Do NOT use a software program to overclock, ever. Use BIOS only.
2) Do NOT overclock your FSB, ever. That will put more strain on your GPU, RAM, HD, etc. Its not worth it.

You should only overclock your CPU, and possibly GPU, depending on your components and temperatures. Some people who know what they are doing overclock their RAM also, but you will get relatively minimal gains by doing so and I don't recommend it, especially if you are new.

Couple other notes:

You should be using Core Temp to check temperatures. Its a free download.
You should read more guides, it is a risky business fiddling around in BIOS without understanding what you are doing. You need to disable auto voltage controls etc. If you leave voltage settings on "auto" again, you have no idea what you may be doing to your components.

ohh thanks mate - advice duly noted.

I read somewhere that increasing the FSB or BCLK slightly, gives more performance overall.

I should just use the multiplier then?

I'm using CPU-Z, GPU-Z and HWMonitor to monitor my temps - is Core temp better? more accurate?

Last question, if I ramp the multiplier to 42 lets say, should i turn off auto-boost and other features like that?

*I read somewhere that increasing the FSB or BCLK slightly, gives more performance overall.*

I read somewhere that adjusting FSB improves overall performance too. Strangely enough, there was no proof to backup that assertion, so I decided not too, because I know for a fact it overclocks things that should not be overclocked. Further, I also know from personal experience that a 3570K system is smoking fast without overclocking FSB.

*I should just use the multiplier then?*

No. You should read guides and learn how to overclock first. You need to understand overclocking involves changing voltages and BIOS settings, and monitoring temperatures so you don't burn up your computer.

*I'm using CPU-Z, GPU-Z and HWMonitor to monitor my temps - is Core temp better? more accurate?*

I use Core Temp because it is one of, if not the most reliable temperature monitoring programs available, and it's free.

*Last question, if I ramp the multiplier to 42 lets say, should i turn off auto-boost and other features like that?*

I am not going to answer that question. You are not taking this seriously enough and I don't want you to be pissed when you break your computer. Please, do your homework - read some guides and learn how to safely adjust the multiple BIOS settings necessary for a safe OC. Changing a few random settings and thinking your "overclocked" your system is risky business. Learn to do it right or don't do it at all is my personal viewpoint.

Someone else may be willing to give you shortcuts for "overclocking" but it is not gonna be me! If you take time to learn more and post all your settings, I will be happy to help.

ha ha ok, you dont need to fuss over it.

I'm not a total retard/n00b i've read a lot about oc'ing and have arrived at this point after many different tests. I even keep notes on paper of settings, temps, Prime95 run times.....

The z77n-wifi does not allow you to alter the vcore of the CPU so it's quite limited in what you can do. For now i'm literally shifting the multiplier and adjusting BCLK while running Prime95 after each adjustment.

I'll DL core temp then so.

Before I really piss you off - can you recommend any guides that i might not have read?

Thanks for your patience :)

You need to find the "advanced" button in your BIOS, probably a "F" function key. Z77 will certainly let you adjust voltage to your CPU.

You are not bothering me at all, I just don't know how much you know about overclocking and don't want you to change settings and be upset with you burn something up.

There are tons of guides across Google.

This is another really good resource:

Yes you REALLY don't need to mess with overclocking at all unless you KNOW what you are doing. The Z77 should give you absolute control over your cpu and motherboard.

If you're going to do it, leave the fsb at 100mhz, and use only the multiplier in BIOS. No software programs. Raise the multiplier/block/ratio a little at a time, run prime95 for a while, and check your temps!! If that is stable, raise it a little more, and repeat.

Ha ha yes thanks - this is what I've been doing all along. I just didn't understand why Gigabyte offer the software option. I read that's its a dynamic overclock not static like the BIOS. I didn't know about 'Intel Burn test' - just ran it, and results are good.

Sorry Adroid - just back to unlocking vCore on my Z77N-Wifi, I couldnt find anyone online who found a solution - even these guys

Is it even possible?

From your guys advice, I wont step into vCore unlocking for a lonmg time :D

Thanks to you both - very informative.

CTurbo - do you think Gigabyte make these boards with vcore limitations but offer a function button to open up CPU voltages. i haven't found anything to prove the latter. I would think gigabyte lock down the cheaper boards on purpose.

Wow. It looks like your board doesn't have voltage control. I am dissapointed that Gibabyte would produce a Z77 board with no voltage control.
-1 for Gibabyte (althought I must admit they are at 100points until today because everything I ever bought from them I was very happy with).

You could maybe return it. Sorry dude!

yep! **insert sad face here**

I reckon they're locking down features on their budget boards the same way Canon do on their mid-range end SLRs.
