8Pack super fast smash the rest i5 Skylake Overclocked, Discounted killer GAMING bundle.

Recently Bios engineers at Supermicron figured out how to unlock BCLK overclocking in non K SKU Skylake CPU. This was followed by equivalent Bios for certain boards form ASUS and ASrock.

On Skylake the BLK clock is not linked at all to PCI X Frequency, SATA Devices and USB for example so what ever BLK you use these remain at a Constant 100mhz so no information corruption or drive degradation can occur.

The choice of the gamer has always been i5 K sku as it has both the clock and cores to play all the games to the max....... So lets make i5 performace cheaper............ and faster!!!!!

This in mind I started testing i5 6400K CPU to find what overclocking could be achieved and the performance of that OC so I could bring out a soft bundle which I support through the forums offering amazing bang for buck.

On all CPU I tried on both the air cooler supplied with this bundle and with AIO 120mm rad water cooler upgrade I could do 4.4ghz Core and 4.4ghz Cache with 2600+mhz DDR4 memory speed. So I can confidently warranty an OC on this bundle upto 4.4ghz. At this speed the bundles performance is exactly the same as an 6600K overclocked to 4.4ghz with 4.4ghz Cache. Further more all my CPU could reach 4.5ghz Core 4.5ghz Cache and 2666+ mems. This OC is not guaranteed but should be attainable for many end users with a couple of extra changes in Bios.
Pics of the Rag




SO here are the benching Results of the bundle at 4.4ghz



Some stability testing with 1hr Real Bench


Cinebench results


And now instructions on how to overclock your buncle..........

First download the necessary Bios from here:
https://www.copy.com/s/t%3AIrITZqcj7...%3Boid%3A15795

Extract and put the file on USB pen drive.

Reboot and hit delete to enter Bios.
Press F7 to go into Advanced mode
Scroll Right to Tools Tab and Down to EZ flash 3 Utility, Hit enter.
Select update via storage.
Then select your USB drive from the list and the bios File you copied to the Drive.
Hit enter to select, Enter to read the file and then enter to flash the Bios.
This process will take a couple of minutes and your system will reboot several times as the MEI is also updated. Dont power down during any part of this update.

Once complete go into Bios again press F7 and set up as the following screens.






Once set hit F10 and enter to save the settings and exit.

Check in the bios that temps are fine. With experience I found upto 1.4v Core is totally fine on this CPU with the coolers in this bundle. Now test for stability with Real bench or similar and your games. If your stable leave. If not bump Vcore slightly and retest each CPU is different needing 1.28-1.38 for 4.4ghz.

For those wanting to push further try these settings below for 4500mhz.


Stability Testing at 4.5ghz


Ok so whats the downside of this crazy performance. Not much really but I must mention.
1) You have no power saving so the CPU runs full speed all time. BCLK overclocking like this means no speed step. An i5 Skylake is burning almost zero power anyway but I should mention.
2) Temperature monitoring with progs like Core temp is disabled so you need to use HWmonitor or the software provided in the motherboard bunble if you wish to check temps. This is ofcourse not the most accurate but does give an idea and like I said previously this i5 is putting out very little heat even with 1.4v and Prime its well under TJmax on Air cooler. Ofcourse the CPU will still throttle and shut down the system should cooling ever become an issue. But in my teating the headroom in terms of cooling was large.
3) IGPU is disabled.
4) updating the CPU microcode via BIOS update or software may effect the ovreclocking of this bundle. So once installed CPU microcode on provided BIOS should remain the same.

Finally why did I pick the other components besides the i5 CPU.
1) The ASUS Z170 -E motherboard was picked as its a low priced Z170 solution which is still feature rich and very solid when overclocking.
2) The Kingston mems as quite frankly Kingston are the don of DDR4 and allow for real OC headroom and stability.
3) The Brocken cooler I picked as it offers truly great cooling on a budget, is very easy to install and the fan is quiet and does not obscure any dimm slots.
4) Finally I included the AIO as an option in 120mm as this offers a silent and solid upgrade to the standard Brocken cooler should the customer require better temps and even higher OC headroom. At 120mm it also fits in almost all cases without issue.
5) Thermal Grizzley TIM simply the best and 1g sizing as perfect for a couple of applications on a CPU mount.

This Bundle is available now at the following link: https://www.overclockers.co.uk/detai...sArticle/59177
For a limited time its also discounted and we are offering with free shipping.

PLEASE INSTALL YOUR OS BEFORE FLASHING THE NEW BIOS AND OVERCLOCKING.

If your a gamer and want 6600K and BETTER performance for LESS MONEY !!this is bundle for you!!! SKYLAKE game smashing, Performance Thrashing not ear BASHING!! Elite tier price Crashing Bundle!!!

ADDED my Bios profile:

Those having issues overclocking this bundle. Flash 050 Bios.

Then if you wish use this profile by placing on USB stick and applying in Advanced Bios setting / OC tools / OC profiles.

https://www.overclockers.co.uk/media/unknown/i54400.cmo

Only this profile is needed nothing else if u go that way to OC

Here are the instructions for mounting the cooler:
Parts laid out!! (PICS = slight RAG TAG... due to my camera phone and marketing team being at Iseries)

Retention ring hooked in.

and secured with clip.

Place the backplate on the back of the motherboard with the holes through the mounting holes on the board.


Screw the mounting post into the backplate.

Place the CPU block head over the mounting holes on the bracket. The inner holes are for this socket.

Screw down all 4 thumb screws one twist on each screw at a time until finger tight. Attach the pump!!

DONE!!!!!!!!!!!!!!!! Any one have any questions about this guide please contact no one..... or moan for no reason!!

From a pure gaming stand point do you think it's worth swapping out a 3770K for an i7 6700K 8Pack ?

I never tested how that chip performs with modern high end GPU like 980Ti.

Possibly yes for gaming but only possibly!!!

For gaming the GPU has a far greater impact than CPU especially at resolutions 1080P and higher.

I wonder if there is any bios which support base clock overclocking for Asus Maximus VIII gene.
Anw, this is really exciting to know that Asus goes wild with MSI and Asrock in this case.

Hi 8pack,

Actually it would be pretty helpful if you ever have an opportunity go back and try the following torture test:

prime95 --> Small FFTs (4 thread), click OK.
hwmonitor --> Check total Package Power (TDP), and the temps.

That will stress it the most of all.

My expectation is (like you say) - the i3 won't be able to draw as much power as an i5. Fewer cores. So it should able to reach a lower stable temperature on air cooling.

It would be very interesting to know actually what those max temps / power envelope are. To compare to i5-6600K.

Prime is fine in terms of temps even at 1.4. I tested a while. But its not a use for end users so I test with real bench, games and VGA benches to check performance on real world apps.

As someone who games and has owned 3770k, 4770k and 4790k, (bit mad yes ) id say not really worth it. The gains arent that signifigant. In games im finding pretty much zero difference between my previous 4790k @4.7ghz vs the 5820k in sig at 4.5ghz. The haswell E runs much cooler though, 64c max as opposed to 75c max. Same cooler and fans and both chips using circa 1.300v.

It's a big saving for those gamers thinking of 6600k its those this is aimed at.

Even better value for gamers though is the
I3 bundle. 285 for i5 crushing single and dual thread perf. Bargain.

I think you should include a disclaimer that intel could block this overlocking on none K CPU's at any time..

No It's a BIOS download that anyone can share. Just like OC BIOS for VGA etc. Really they can't stop it
at all. If Intel block this at hardware level then we pull the bundle.

Yeah I know. Just meaning to establish / know for sure that top end outer bracket of the power envelope would be. And to be sure that the cooling is always enough to keep. i.e. that level which cannot ever be exceeded by the CPU because it physically isn't able to go above.

For comparison (when I did that exact same test on an i5):

My i5-6600K, with inadequate cooling and cheap regular paste. It gets up to a consistent 119.75 watts, and 100^C on that specific test. So unlike the i3, not thermally balanced / stable. (Although to be fair i didn't permit it the CPU fan to go any higher than 857 rpm.)

I suppose you're right it doesn't really matter much because the system will never be used that way in real life.

The regular 'full load' testing TDP (various other benchmarks) all get that same i5 chip either 55 watts or 77 watts TDP. And 70^C temps. So it should always be less for the i3-6100 (having fewer cores). Despite similar single-threaded performance.

Kindda makes we want to get rid of the i5 now (sell it). But then again I've no graphics card yet. So couldn't OC it until Pascal / Arctic Islands comes out.

Sorry but I think you are incorrect. For example:

http://www.bit-tech.net/news/hardwar...ocking-block/1

They released the update as a "stability" update via Windows update. After that, no more overclocking on cheap boards.

They will release a microcode update and boom... blocked again.

OK the common assumption (myself included) was that Intel microcode updates only ever get backed into future BIOS updates. Meaning that so long as you don't ever re-flash your BIOS, you should be OK. You seem to be referring to this bit:

For the article's user comments:

> "AFAIK Microsoft only do this for critical bugs, so in theory you could just use a older BIOS ROM."

The correct way to deal with windows update, it to disable it first. Then use the WSUS Offline tool (e.g. from a weekly scheduled task) to download and install any new windows updates. The WSUS tool can block / exclude KBs too, but only if you know and are aware ahead of time which KBs to look out for.

Or just use linux. Linux isn't going to silently install microcode updates without telling you beforehand.

Processor manufacturers release stability and security updates to the processor microcode. While microcode can be updated through the BIOS, the Linux kernel is also able to apply these updates during boot. These updates provide bug fixes that can be critical to the stability of your system. Without these updates, you may experience spurious crashes or unexpected system halts that can be difficult to track down.
It will be blocked as a "stabilty" update. Unless you want to overclock and not connect your PC to the internet ever then I really do not recommend relying on it.

I think you are wrong about the linux for sure... Because for all the major linux distros, none of them will update the intel microcode except by a manual process (which is distro-specific), and always requires to be initiated by the user.

It's only Microsoft that may silently apply intel microcode updates without the user explicitly telling it to do so. But even so, it's my current understanding that is not terribly likely to happen there either though.

Furthermore, Intel has release no public statements yet (or at any prior time) that they are against BCLKing. And given the cetainty of cheaper hexa-core unnlocked AMD Zens entering the market in coming months. Intel will want to stay ahead / price competitive with Zen. So to start blocking this new BCLKing would be not be any kind of a rational move for Intel in light of that.

Yes I agree it is unlikely with Linux. But my point is that Intel can easily block this if they wish to do so. They have a reason to block it, it harms sales of the K series CPU's, who in their right mind would buy a 6600k over an i5 6400 if BCLK was offcially unlocked?

After all they blocked the B85/H87 chipset from overclocking as it harms sales of the Z87 chipset. No amount of staying on the right BIOS fixed that, it was pushed via Windows update.

Asrock even state:

Quote:
4. Due to future hardware/firmware updates or other reasons, the availability of SKY OC is subject to change without notice in advance.
http://www.asrock.com/news/index.asp?id=3132

To just brush it off as "it won't happen" and to not put any kind of disclaimer I think is just crazy!

If u use the micro code in the BIOS provided and don't change BIOS then this is ultimately fine. I mean how many times does anyone need to change BIOS. This is a bundle we are supporting on the BIOS provided.

The OS does not dictate microcode BIOS does. On asrock OCF u can even select the microcode u wish to use from within the BIOS its self and switch accordingly.

Intel may be pleased about this at i3 level. They have great extra publicity and a chip now that beats AMD in the same price bracket.

Sales of such chips should explode with this.

I dare not update the bios when everything is tweaked as I like it and there's no features I feel like I'm missing.

Props to OCUK for doing this.

I cant describe enough how much I miss FSB overclocking :P
