Excellent guide, thank you!

I'm currently running my 2500k @ 4.6GHz - Stock Vcore (1.270V - 1.280V under load). 4.8GHz can be reached with about 1.3 Vcore. But after that it just starts to go downhill for me. Lot of 0x124 BSODs and stuff.. I think this 4.6GHz setting might be good for me in the long run, but am still very curious to see if I can reach +5GHz ... I seem to have gotten a descent chip, but I think it's the 4+1 power phase of my cheapo Asrock Z77 Pro 3 and not so great Arctic Cooling Freezer 13 Pro cooler that's holding me back...

Also, the CPU LLC is named totally different on my Z77 Asrock board (don't know about the other models).. I have options: Auto, 100%, 50%, 0% (100% raises the vcore the least under load). You might want to add that to the guide. rolleyes.gif

It might be kind of tough for people to answer since the z77 is a new board and most people posting in this thread have z68 or P67. But i wouldnt think you would have to up the VTT just so you can set your ram at 2133 unless your overclocking it. Have you tried manual settings instead of XMP profile?

Got it to finally work. The Z77 motherboard works exactly the same as the P67 and Z68 in terms of the BIOS. Had no issues there.

Running it stock didn't work, but upping the DRAM to 1.6v did. It's rated at 1.5v but I'm really not worried as I can easily play with the timings with this voltage.

Thanks for your help.

Correct me if I'm wrong but Z77 is mostly for Ivy Bridge right?

This guide is for Sandy Bridge. It's just beneficial that most of it carries on over to Ivy Bridge. I don't have the time to keep updating the guide for all the new boards that come out tongue.gif. Most importantly, I don't own a Z77 and so I can't write a guide from experience. frown.gif

Z77 works on both IB and SB. Many that were disappointed with the IB after waiting for it bought/will buy a Z77/SB combo. smile.gif The only thing you can fully utilize on a Z77 board with an IB and not SB is native PCIe 3.0 communication between cpu and the graphics card.

I do understand your point about not having time / firsthand experience of Z77 to update the guide. I just thought to point it out as all of my other settings came from this guide, but the LLC values are named a bit different, thus can confuse someone. redface.gif

I used this guide for my 2500k on a Z77. It's the same processor and the chipset doesn't make a difference.

So to Kenny, go ahead and throw in Z77 as a working chipset for this guide on ASRock boards.

Wow really? Its rated at 1.5v for 2133mhz but it took 1.6v for it to be stable? I would probably look into that, either through the manufacture or possible RMA.

I'll contact them but it would be more worrisome to have to send it in as it's my only set right now. It's it's 0.1v higher it's not going to cause problems. If I can tighten timings at this voltage, I'm content.
post #439 of 9489
Thanks for this guide. I'm able to run 4.8Ghz w/ +0.060v Offset & Load-Line Calibration Level 2(it crashes it i set it to Level 3).

Is the offset better than the fixed voltage? The reported vcore voltage is averaging at 1.440v (min=1.432 - max=1.456).
What Fixed voltage should it have? Sorry i have read only up to page 26.

Thanks again.

Thanks again.

it's dependent on LLC. I've set my fixed to 1.5v and LLC kept it from hitting 1.5v. I'd suggest finding out what your max stable voltage is and setting it manually, then adjust your LLC accordingly until the voltage is at your max on load.
