Good nes indeed, any site made a report on how nice the rest of the elements dependant on the bclk take the oc? Specially ram speed and stability

The ultimate combo would be a low clocked (and lowly priced, obviously) 4c8t 1151 xeon in a b150/h170 board with a bios mod to widen the cpu support list and get over the sad lock intel made on 1151 xeons not to work on consumer chipsets. Oc via bclk and you would net a killer system.

Is there anything to gain with BLCK tinkering vs multiplier adjustment on a K cpu?
I haven't played around with the baseclock on my 6700K yet, but the big thing is that it allows for much finer control of the final clockspeed. My old Phenom II, for example, wasn't quite stable at 4100 mhz but was rock-solid around 4065.

Asrock will expand the list of compatible MBs:

The SKY OC update currently only works on motherboards with Intel's Z170 chipset. However Asrock says that more motherboards should be expected to support the update soon. Asrock claims it has achieved a 19 percent boost on a Core i3-6100, a 32 percent boost on a Core i7-6700, and a 36 percent boost on a Pentium G4400.- PC Gamer
MSI MBs also support BCLK OCing now:

Now, a BIOS update for MSI motherboards brings support for this method of overclocking on several of its Skylake models, allowing users to overclock locked Core i5, Core i3 or even Pentium processors. Right now, the MSI motherboards capable of this include:

XPOWER GAMING TE
GAMING M9
GAMING M7
GAMING M5
G45 GAMING
Latest BIOS here.
Core i7-6700 @ 4.8GHz (MSI XPOWER GAMING TE):

If you can OC a combination of H110/B150 + Core i5 6400 it would be great for gaming PCs.

Newegg has an ASRock Z170 Pro4S ATX Z170 with "SKY OC" beta BIOS available, for $80 + $3 ship.

I guess, you could order that one now (I did), or you could wait and see if some of the H110 mobos support non-K SKL OC.

Uff, my Skylake NUC is already delayed. New delivery time seems to be between xmas and new year.

At this point I'm not even sure I would get a H110 MB. Cheapest LGA1151 motherboards are what, $50? Unless you're extremely budget limited the extra $30 is well worth it for a superior Z170 MB.

Yep. 30$ for free memory selection above 2133Mhz, RST support, RAID support, 4 DIMM slots, +3 M.2 slots, +2 SATA +6 USB 3 (+4 total USB), 20 PCIe 3.0 lanes contra 6 PCIe 2.0 and the ability to split the CPU x16 if you choose so and a better board. The H110 is around 10$ cheaper than Z170. The other 20$ is motherboard components.

I agree. I made a mistake jumping the gun and grabbing a H110 board. It figures, though, that I see the $80 Z170 board after I ordered that one. Oh well. I can always use it for some future build, or possibly, Asus will eventually release an OC BIOS for it.

I don't think that I would go that far. The $80 Z170 board does NOT have three M.2 slots. If you want those, you'll have to still go for a $180 board.

Its the chipset options, not whats nessesary implemented.

My Z170 ITX board also only got 2 M.2 slots and 2 DIMMs for example. And certainly not using anywhere near 20 PCIe 3.0 extra lanes.

The point is that H110 contra Z170 in chipset cost alone is peanuts (~10$).

What is the significance of the TDP differences between the two different steppings of the G4400 SKL Pentium dual-core 3.3Ghz CPU?

1151 Intel® Pentium® Processor G4400 QJP8 3300Mhz 65W
1151 Intel® Pentium® Processor G4400 QJZK 3300Mhz 47W

From here:
http://www.biostar.com.tw/app/en/mb/introduction.php?S_ID=805#cpu

Hmm, actually, those are ES steppings, 4-character codes starting with "Q".

Anyone know what the TDP of the retail G4400 stepping is? Is it 54W?

Looks like a 54 watt chip!

Right now it's only available for Z170 motherboards. Good news is, all of them will support BCLK overclocking, including the $99 Z170M Pro4S.
Seems like they all go to 4.4-4.5G regardless of starting freq.

Can you return it? Z170 should allow you to OC that CPU and you'll get a lot more bang for the $ you spent on the CPU.

Honestly, an overclocked G4400 sounds like a fun system. Bet you can push it to ~4GHz+ on reasonable cooling.

Knowing that business are now working at 100% during those times and considering the weather of that place, expect getting the machine next year :V

Next one is ASUS. Looks like the popular Z170-A model supports BCLK overclocking too. Managed to push a lowly Core i5-6400 (2.7GHz base) to 4.8GHz! :)

ASUS BIOSes up for Download

Hwbot said:
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.

Almost missed this, from a few days ago:

Overclocking.Guide: Overclocking Non-K Intel Skylake CPUs (Performance Tests!)

Test Setup:
ASRock Z170 OC Formula
2 x 4 GB TeamGroup DDR4 3866 MHz
NZXT Kraken X61 AiO
Windows 10
Pentium G4400T
Core i3-6320
Core i5-6400
Core i5-6600K
Core i7-6700K





However, it’s just a matter of time until we will see unlocked BIOS for cheap Z170 or even H170 boards. In the end this is still the best OC-News since Sandy-Bridge considering the fact that I could gain +75% OC which results in +52% performance.
