It's new link for all Z87 boards BIOS's, not only asus.......
Link has been changed yesterday and Owi still keep not connectable link under "Latest BIOS: LINK"
on post #1.

Must be magic......4.5ghz...Vcore 0.000V

OMG! Tested linX 10.3.7 at 4.2Ghz @ 1.1v (Bios) and hanged after 10 seconds!

4.1Ghz @ 1.1V (Bios), 1.193v (CpuZ), temps at 81-87'c 

[attachmentid=3496334]
Now I'm a bit irritated by "adaptive" mode. Mind telling me the minimum setting for manual mode (it is override mode right?) if I want max CPU voltage to be 1.15v?

Should CPU voltage be override to 0.700v and CPU voltage offset +0.35v?

Damn... have to do more research.... 
1.15v in BIOS or CPUz?

Right, so if I want CPU voltage @ 1.15v max, I should set something like this?:

CPU voltage 1.05v
Digital I/O offset 0.1v

Will try out and see.....

Errmm.. BIOS screenshot? Dunno! 

Right, will try.

CPU and cache voltage to full manual at 1.15v right?

Errmm... vcore maintained at 1.100v leh... didn't throttle down eventhough speed went down to 800mhz....

Sorry sorry... I set 1.100v in BIOS. CPUz showed 1.099v.

However, CPU voltage didn't throttle down to 0.700v although speed went down to 800mhz....

What I wanted was the vcore to throttle down too. Like your example where your proc was running at 0.00v or 0.15v! 

However, I would be happy if I can get it to go down to 0.700v @ 800mhz. 

If you testing GB OC,use BIOS B10.........(good for PSC)

Manage to get a stable 4.4ghz with silver arrow (non extreme) but a very high temperature of 100 degree max. I think I should went with the line method with the thermal paste. Here's the result. I put it in spoiler because I don't want to flood the page.

Just went thru all various Z87 OC Guide (Asus & Gigabyte atm).

After many "new records" or "Total Domination!" and OC Guide for ES chips, from
various companies (persons), done all with Engineering Sample (ES) or Qualification Sample
(QS).............QE6S - Asus (need FIVR baypass) / QEH6 - Gigabyte (became QS Prime for Retail).

Is nice to see what ES version can do but........it's time for them to turn the page and start to look in RETAIL version
as we all buying Retail version which didn't perform as ES.

Will the overclock headroom with HT Off??

Seems like no one do HT OFF oc nowadays
I myself is very much curious to know how does it fare with less heat generated by the processor

on a more depressing note, I can't even get my vcore to go above 1.000v with this Asrock Z87E-ITX.

Spent some 30 minutes or more with the interface with no luck bumping vcore. Probably one of the worst UEFI / BIOS i ever use.

thanks. I don't use that many Asrock boards.

I've no problem with MSI / Asus boards. Looks like I'll have to try again.

As you know, UEFI / Manuals are almost never helpful.

Die (made of silicon) is to sensitive to do soldering and the top layer of the DIE is not conductive.
Edit:
Hmm,seems upcoming 4960X coming with soldering IHS:

and other thing is why no Haswell from Costa Rica.

OK finally got it OCed.

Tested stability with video encoding.

4.4ghz failed no matter how I tried, even with 1.35vcore.
4.3ghz 1.25 vcore = passed.
4.3ghz 1.225 vcore = passed.
4.3ghz 1.20 vcore = failed.

Using the Cooler Master Seidon 120M, AIO WC unit. Testing the product ........ not exactly an impressive AIO setup. I feel that my air coolers can do similar / better. Can't do comparison now cos this ITX board is really small.

Will be getting ATX LGA 1150 board(s) next week so another round of OCing would ensue.

Why video test instead of prime95? I can't get the CPU to run straight at 4.3ghz. Disabling Speedstep / TurboBoost results in default speed only.

Prime95 on the above setting doesn't push it to 4.3ghz, just hovers at 3.8ghz. The video test pushes it to 4.3ghz though.

Now I go do further test. See if Prime95 can push it to 4.3ghz for further test.

*ok I just ran Prime95 Small FFT test (didn't run the suggest test in 1st post cos that one doesn't push it to 4.3ghz) and the AIO WC couldn't take it.
