Overclocking Locked Intel Skylake CPUs Possible - i3 6100 Benchmarked

The days of Intel overclocking being limited to their more expensive unlocked parts appear to be over, as TechSpot has posted benchmarks from an overclocked Intel Core i3-6100 using a new (pre-release) BIOS update from ASRock.

"In overclocking circles it was recently noted that BCLK (base clock) overclocking might become a possibility in Skylake processors. Last night Asrock contacted us with an updated BIOS that enabled this. We jumped at the opportunity and have already tested and benched a Core i3-6100 Skylake CPU with a 1GHz overclock (4.7GHz) on air cooling."

The 1.0 GHz overclock was achieved with a 127 MHz base clock on the i3 processor, with a vcore of ~1.36v. Apparently the ASRock motherboard requires the processor's graphics portion to be disabled for overclocking with this method, and TechSpot used an NVIDIA GTX 960 for test system. The results were impressive, as you might imagine.

The following is a small sampling of the benchmark results available from the sourced TechSpot article:

The overclocked i3-6100 was able to come very close to the multi-threaded performance of the stock AMD FX-8320E (8-core) processor in Cinebench, with double the per-thread performance. Results from their Handbrake encode test were even better, with the overclocked i3-6100 essentially matching the performance of the Core i5-4430 processor tested.

Gaming was underwhelming, with very similar performance from the GTX 960 from all CPUs at the settings tested.

So what did the article say about this new overclocking-friendly BIOS availability? "We are told this updated BIOS for their Z170 motherboards will be available to owners very soon." It will be interesting to see if other vendors offer the same, as there are results out there using a SuperMicro board as well.

I honestly thought Intel wouldn't let their board partners enable BCLK overclocking on locked CPUs, this is a very pleasant surprise.

Another interesting feature snuck into ASrock's Z170 ITX board (and possibly others, but it's less interesting there): PCIe Bifurcation. This allows you to use a passive riser cable to split a x16 slot into two independent x8 slots. Other ITX boards that are known to support it are ASrock's X99 ITX board (requires a special firmware, email ASrock for it) and Z87 ITX board (again, special firmware needed). The Z170 Gaming ITX has the option avaialable out-of-the-box.

Why not just use an mATX board for dual-GPU? Because that's bigger than you need and wastes a lot of board space and thus case volume, and stuffing a dual-GPU powerhouse into a 12L chassis is proper Because I Can PC-building behaviour.

I'd love to see someone put two Furys of some sort in an SG13 or Ncase, and watercool the whole thing.

That'd be absolutely mental.

A DTX board with a pair of single slot waterblocks seems like an easier option, and any case that supports ITX with dual slot GPUs with support that.

The downside is availability (or lack thereof) of DTX boards in anything other than the low-end Hxx and Bxx series chipsets, the 'extra' slot being either x1 or x2 on all DTX boards I've seen, and having the GPUs stuck in that location sticking vertically out of the board. If you're going to put in a pair of flex risers anyway to move them somewhere better, you may as well use a flex bifurcation riser to start with and save that extra bit of board space.

I3 only?

According to the source, TechSpot, no, it's all locked CPUs that can be overclocked this way.

Check The TDP guys 65watt the i3 6100 is not a 65watt part

December 13, 2015 | 06:16 AM - Posted by Fasic (not verified)


Yes it is 65w...

Wow, what a troll. According to the very link you posted in your comment the Core i3 6100 has a TDP of 51W.

Move over, G3258.

i3 6100 oc + $20~30 cooler would be a very nice choice for gaming.

I'm going to get a i3 6320 and BCLK oc it .. I think it would make a very nice budget gaming system.

C'mon PCper, we know you love Intel because your on their payroll. Why don't you include AMD's Carrizo in this review ? I've been asking you to do for a while. You know its a great APU, at least give everyone an idea on how far AMD have come. PC per's bias against AMD is sad.

Since you are obviously in touch with Intel's payroll department, can you please find out why I haven't recieved any cheques from them yet?

does the ASrock Pro4S z170M board work with overclocking the i3-6100?

What are the full specs of this whole setup?
