B10 is the extreme BIOS apparently... I wonder what the difference is between the two. Does Gigabyte ever release changelogs? That would be incredible helpful in this whole process.

Thanks for buying the Z77 MPower, now go buy the Z87 MPower!

I was not able to get EasyTune to install in XP. GB is working on a GTL (Gigabyte Tweak Launcher) that should work with XP. Unknown if it will support BCLK overclocking or not. I've never looked in Device Manager because I never install USB3.0, audio, or Lan drivers for XP.

I do not. I'd google it but I suspect you've already done that and I'm leaving work now!

Rfb*20 = ~Rvr where Rfb is the resistance between the FB pin and ground and Rvr is the resistance for the trimmer pot. So yes, you're correct.

For the memory vmod, it looks like FB on APW7165 is 6 and GND is 3. Source However, from the OCN competition we did a few years ago with these cards, extra memory voltage really didn't help. If you could get some better photos of this, it would most likely help a bit.

Yeah, that's the correct NIC: Source Thanks Steve for the image.

Yeah, that would be great. Is it the Z77 IME? Or were you able to install the Z87 W7 32-bit version in XP?

Thanks! Going to try raising input voltage... I've been having trouble getting stability with anything over ~4.7-4.75 for high load stuff.

I hate that all the secondary and tertiary timings are in a different order/have different names from the Z77 boards. As soon as I was getting the hang of it it all changes

I meant that I think some of the earlier scores we saw posted where it looks like 2V+ was used might have actually been using less voltage, it just looked that way because they used older CPU-Z. We need someone to be brave and test a delid with extreme cooling.

Windows XP? Can you check which version it is?

Steve, is B10 the newest BIOS?

I think all of this stuff we've been seeing about 2V+ is due to bad CPU-Z. Use 1.64.2 from the CPUID Haswell Reviewer kit: http://www.cpuid.com/news/76-reviewer_kit_for_intel_haswell.html It says it contains 1.64.1 but the file actually has 1.64.2 in it.

:banana:

Nice

Do you mean the Intel INF drivers or the Intel Management Engine Drivers? At this point, Intel has not released ME drivers for XP. I have searched Intel's site and they were only for W7 and W8. https://downloadcenter.intel.com/Detail_Desc.aspx?agr=Y&ProdId=3598&DwnldID=22596&ProductFamily=Desktop+Boards&ProductLine=Intel%C2%AE+8+Series+Chipset+Boards&ProductProduct=Intel%C2%AE+Desktop+Board+DZ87KLT-75K&lang=eng So for now, BCLK adjustment will not work in Windows XP.

I just wanna go fast

For the buttons to work, EIST has to be enabled. Once you set the high performance mode in W7, it should stop downclocking. Are you having the issues in XP too? Or are you running Pi in W7 (noob )?

Anybody try LN2 on these things yet?

For BIOS F5b CPU stuck at 800MHz is one of two things: LN2 Switch is on "High Performance" needs to be selected in Windows 7 to keep it from throttling I have had issues with Uncore multi not changing anything... I'll experiment with that more tonight. The multiplier buttons work perfectly for me in Windows 7 and Windows XP. The BCLK buttons only work in Windows 7 for me. Install your OS Install Intel Management Engine (V9.something) Install Intel Chipset INF Drivers Install Gigabyte "OC Button" Driver Enable EIST in BIOS. Disable all other power-saving features (C1E, C3, etc.) Hit Windows Key and type "Change P". "Change Power-saving Settings" should be the top result. Choose that and then click the arrow by "Show additional plans". Select "High Performance". I haven't frozen my chip yet so I have no idea about the Vcore limit. Perhaps you need more input voltage to allow that much Vcore?

From what I've heard, chips shouldn't actually need more than about 1.75-1.8V to hit their max frequencies, even if it's around 6.7GHz. A lot of the screenshots from Computex are using old CPU-Z so they're reading vcore wrong. Just waiting on the OP to be updated...

What do you have the IMC volts at?

You kill the ES 4670K? Or a retail? What volts were you running?
