Unlocked BCLK for All Skylake CPUs by ASUS and ASRock. Update: ASUS, ASRock, MSI BIOSes up for Download

It looks like the Saga of the Unlocked BCLK is coming to a bursting conclusion with both ASUS and ASRock enabling overclocking the base clock frequency of non-K Skylake processors. From the looks of it, a simple BIOS trick will enable the overclocking capabilities.

We will update this news article with the links to the BIOSes enabling the BCLK overclocking when they appear on the web. Until then, have a drool over Elmor's 5.8 GHz Core i3 6300 or L0ud_sil3nc3's 4.9 GHz Cinebench R15.

Update #1: Elmor posted a bit more details on the unlocking in the forum. For now the BCLK unlocking is in experimental stage with most obvious drawbacks being the lack of power management functionality and some benchmarks like XTU not working properly. The BIOSes will arrive in the coming days as more fin-tuning is required.

Update #2: the ASRock Z170 OC Formula 1.92 BIOS which supports BCLK overclocking for non-K processors is now available for download. It's available in our Z170 BIOS, tools, facts, stats and list of mainboards forum thread, in Der8auer's article titled "Overclocking Non-K Intel Skylake CPUs (Performance Tests!)" at Overclocking.guide and thanks to Splave's original upload at XtremeSystems in the ASRock Z170 OC Formula support thread.

Here's the download link from our HWBOT servers: download.

Update #3: after ASRock now also ASUS and MSI have uploaded BIOSes for their Z170 motherboards. Elmor has uploaded the BIOSes for 7 motherboards: Maximus VIII Hero, Maximus VIII Gene, Maximus VIII Extreme, Maximus VIII Impact, Z170-DELUXE, Z170-A and Z170-E. Note that these are in fact BETA versions of the BIOS and there is thus a long list of issues and warnings: no IGPU, No dynamic change of CPU frequency, No C-states, No Turbo Mode, CPU temperature reading is incorrect, AVX instructions have very low performance and Windows XP ACPI not supported. You can download the BIOSes here.

In the MSI Z170A XPOWER GAMING Titanium Edition official support thread, Pepinorang has also uploaded the non-K OC BIOS for the (duh!) XPower motherboard. The washlist of issues includes the same as mentioned above. You can download the BIOS here.

Super stoked about this! This is a pretty huge deal and may have big consequences ...

:celebration:


Greece TASOS says:

Thank god ... at last !!!

Let it be true ... or more correct , let it be done !!!

We wont have a celeron 300A again
But we will have something fairly good.

Cheap overclocking !!!

Cheap performance to the masses.
That's how and that's why ... overclocking started , in the first place.

Now give us powermanagement and i'll run this in my daily...! :D
Seems like Gigabyte and MSI are still missing, though.

Hope Giga is close!

Shouldn't be too long ...

Game on! This could become some epic stuff over the winter :)

United States Splave says:

Fun for cheap chips!

websmile says:

This is really fun, I have to learn a lot on BCLK OC and it not like shooting on a sitting duck (at least for me :p ), but that´s real fun :D - despite starting at zero I can´t remember having had that much fun like I had today at the few hours I tested this. With good settings there should be much more in this cpu, air cooling, safe volts

Looks great websmile, glad to see bios working well for you and have to agree it's a good time benching bclk locked cpu's again, feels like 920 days @ X58, endless possibilities.

Intel we promise to keep buying K sku, plz don't lock us out :D

Lets hope not... this should bring more overclockers because its so cheap... bclking is fun...

Germany Tzk says:

Glad MSI figured it out too...
Now get us working Powermanagement and OC support on low-end boards :P

Sweden Rauf says:

A word of advice. I pushed 1.85-1.88v through my 6320 on ln2, just like i've been doing on my 6700ks. CPU got heavily degraded after just one hour of benching. Now it performs like 700mhz lower on ln2... Be careful with volts on these chips!

No chance you just had a bad mount?

United States Splave says:

did u delid? mine hits 70c in bios 1.55v water

websmile says:

I did set mx of 1,4v BIOS for Pentium, if readout was OK around 60c on air at 4,7ghz+, not degraded so far. Subvoltages were pretty high on auto, so I lowered them a bit, opted out at 350 bclk at tests, maybe also because of this

The biggest drawback might be the low AVX performance ... :(

Australia zeropluszero says:

Just hassle intel while you're there PJ.

No :)

Splave said: did u delid? mine hits 70c in bios 1.55v water

Yes, delidded. Tried it again on Impact to rule out that it wasn't MB related. But same result there. Maxes out at just above 5000MHz now on LN2...

Awesome asrock has unlock available on all mobos

Greece TASOS says:

Sceptic about this photo ... (not anymore)

While ASRock SKY OC breathes life into Intel® non K series CPUs, currently it is still exclusive to motherboards with Intel's Z170 chipset. But have faith in ASRock's skillful engineers, sooner or later more Christmas gifts from ASRock are going to be delivered.

tested the bios downloaded from here on asus maximus viii hero i3 6320 @ 4600+@1.45v. ran gpu pi, geekbench, cinebench r11.5,15, hwbot prime, wprime. working nicely and the gains in performance in line with overclock.

got 213 marks with xtu though.

That's why ?

Poland phobosq says:

That's the drawback of unlocked OC, either you get high clocks or full performance. It seems that BIOS update cripples some of the capabilities.

xtu screenshot

i3 6320@ 4289-----213

throughout xtu temp is showing 100(not working). it can't be. on custom water cooling with ekwb x360 kit with 1.33v vcore.

i3 6320@3990------735

Bulgaria Xaltar says:

Looking forward to getting into this myslef. Interesting that the AVX performance seems to be taking a hit. We may see some more BIOS updates that fine tune and correct some of the drawbacks. From ASRock's info it seems that only their Z170M based boards suffer from the temp reading issues, can anyone confirm this from other manufacturers?
