ASRock Z68 Professional Fatal1ty Gen.3

4.8GHz with turbo Obamalover. The rest was with Asus software. When I boot, its 4.8GHz.....

[Deton]

why? even if turbo is disabled? I just built a 2600k system for a friend and i disabled all that crap and used a manual oc of 4.5ghz on a crappy $100 board its prime95 stable.

I don't know what board you have and how you did it but when you OC SB, the Turbo must be enable. This is how SB works, overclocking SB is not the same as Bloomfield.

4.5Ghz is just like a walk in the park for the 2600K. Now try above 4.8Ghz as you have C1E, EIST and Speed Stepping off, I'm sure your system would crash or BSOD.

Are you saying turbo should be left on? I don't really understand the sandybridge cpu very much so i would appreciate if you guys could enlighten me.

Yes it has to be ON...I don't know about the other boards but my ECS board won't OC the 2600K if I turn it off.

For example are you saying that you have oc'd to 5ghz and turbo is still able to oc higher?To me turbo is the stupidest thing imaginable. I dont want the cpu ramping up the frequency when it wants to i want it ramped up all the time and to where i choose it to be. Another question i have. why doesnt windows detect the correct cpu frequency? windows says 3.4ghz cpuz says 4.5ghzdr death anyone?

Turbo is still on even with 5Ghz but you have manually tweaking the voltages. This is how you OC the K series chips.

DrDeath didn't do this, he just used One Click Auto OC feature and the board gave him 4.8Ghz out of the gate.

As you last question, you wouldn't have constant Oced freq with SB. This is how Intel designs the SB; power efficiency, it's only jump to OC freq when there are load...........Turbo baby.

[Drdeath]

Deton, I had a constant OC frequency. I disabled C1E and C6 and all features. Just enabled Turbo. The board rebooted and 4.8GHz. Whalla. I will take screenies of the bios hold on......

Then it's depend on certain boards, my won't let me do it, I think. I haven't mock around with SB much thought, I must have a revisit it.

no need bios sceenies, we need CPU-Z screenies at idle

[Drdeath]

On Asus and Asrock boards, all you need to do a screen shot is have a USB Flash Drive installed and hit F12 for bios screenies gents...

[Skyguy]

Ya, on P67/Z68 there is no need to turn Turbo, etc off. Just leave it on, along with EIST, SpeedStep, and all that other stuff we used to have to disable for overclocking. It's a different game now with this platform.

obamaLOVER? you might as well kick me in the nuts!

[bullydog]

okay so it does work when you disable all Powersaving functions while OC'ing SB. But I'm starting to like the way it is with all that Power saving features. I currently use the preset 4.8ghz setting as it idles at only 1.0++vcore and when the load comes in, the 1.44v kicks in. This is really very helpful as my room is always very warm 30c ambient, as it wont heat up my room further, rather than running it constantly at 1.4v it probably degrades the CPU faster

[Drdeath]

If it is stable with power saving features enabled, let it be. Run a stress test to verify....

[bullydog]

Yup verified its LinX stable

[obamaliar]

i think this is the board i will buy. was going to hold out for z79 but all that sata3 goodness has changed my mind.

[Drdeath]

It was my 1st Intel review but I thought it kicked ass.

[Doctor_Death]

Bully, do you have problems hitting 4.8GHz at 1.38v , or do you have to use 1.4v ?

[bullydog]

Bully, do you have problems hitting 4.8GHz at 1.38v , or do you have to use 1.4v ?

I managed to hit 4.8ghz but my chip requires 1.48v which is way too high so i backed off a little and currently on 4.6ghz, I wish i had a better chip
