Did I get a bad 4670k?

Paired with ASRock Z87 Extreme 4.

I can't get past 4.0 using bios. Only 4.1 using the A-Tuning software, and 4.0 is max using Turbo Boost.

A-Tuning was at 4.1 with vcore at 1.2. I thought certainly I could get to 4.4. Not even 4.2! I haven't given up, but I've abused Windows enough for one evening.

Suggestions? I've done quite a bit of reading up. OC'd plenty in the past, but this seems a bit different. Possible just didn't get a good chip?

I started at 1.2 vcore @4.1 because it was stable for auto tune. Went to 4.2 and started bumping vcore by.05 increments. Would either freeze or blue screen each time. Everything this else on auto except ram, which is using the XMS setting cs 9 settings.

An update. Updated BIOS to 2.70. Sitting at 4.2 with 1.22 vcore. One core barely touched 70 running prime95. Attempted 4.4 @ 1.25. Barely got back into the BIOS to reset. May attempt 4.4 again at 1.3, but happy enough with 4.2.
 
well what cooler do you have? if your only hitting 70 im guessing its decent. dont use the in windows settings, you should go into the bios an manually do it. as far as ivy/haswell, from what ive seen, once they get above 4.3-4.4 they start requiring sandy bridge level voltage to be stable.

This is in the bios. Started out using the software to see what was stable, then manually made the change in the bios. Before the bios update, I couldn't even get to 4.2, even using the software. Recommendation on where I should start with voltage to hit 4.4?

Almost forgot, using the Hyper 212 Evo.
 


So you're at 4.2 with 1.220 Vcore right now? I say don't go to 4.4. Get it stable at 4.3 first.

Increase Vcore to 1.250 @ 4.3 and see if that works. If not, increase Vcore to 1.260 v. and try again. Increase Vcore in steps of 0.010 v. until stable, up to a MAX of 1.300 v. DO NOT go above 1.300 v.!

You may find it more convenient to make your changes with the Intel Extreme Tuning Utility. It does not do any "Auto Tuning" but it does allows you to make changes without rebooting your system: http://www.intel.com/content/www/us/en/motherboards/desktop-motherboards/desktop-boards-software-extreme-tuning-utility.html

Lots of good tuning info in this thread which helped me to get to 4.6 on the system in my sig: http://www.tomshardware.com/forum/id-1722630/intel-god-quick-dirty-guide-4ghz-haswell.html

Yes, stable at 4.2 with 1.22.

Are you suggesting using the Intel Tuning and not the BIOS? Or use the software to find the right settings and manually set those in the BIOS? I've always been under the impression BIOS OC was best way to do it. If there's no appreciable difference, I don't mind software doing the work.

Again, 4.2 isn't terrible, and works for me, but 4.4 or 4.6 would be pretty sweet.
 


Use the SW to find your settings then set them in the BIOS. Sometimes the settings in IXTU don't get saved when you reboot.
