Awesome Deal

First of all, Thank you again OCUK for the great service, ordered Friday 5 pm got it delivered Saturday at 2 pm.

The bundle is great, fast and very easy to setup. Just followed the instructions in the forums and got it running to 4.4 GHz in no time.

If you are looking for a cheap oc in a i5 look no further.

Best value

Running at 4538 small OC on shipped ram

This hasn't missed a beat, and is rock solid stable.
running since march 16 with windows10 updates on, and no issues.
8packs instructions are comprehensive, see forums.
This crunches any game thrown at it. there isn't any reason to purchase anything else if you want a top end gaming machine

I, like the other guy who reviewed this wasnt sure if it was right for me. I wanted a upgrade that I would notice. Anyway after looking at reviews and YouTube I decided to go for it. You have to overclock it yourself but it is very easy. There is a page on the forums which is a step by step guide including pictures so you defiantly can not go wrong. If I can do it anyone can. I play a lot of online games, this rig rips through everything I have put it to. I'm using a 1080gtx with it and I can honestly say it's brilliant. I wanted to put it to the test on the most demanding games. So I bought Doom and rise of the tomb raider. Put them both on ultra, absolutely destroys them and it doesn't even break a sweat. If you are wanting a decent rig without paying through the nose. This is the one for you. I've bought from overclockers for many years now they have never let me down. Of course the haribos go along way too.

Great setup - Easy to use, running so well at 4.5ghz

This is my first ever review after many years buying from Overclockers and various places, but I have been so happy with my purchase I had to leave feedback.

To start off with I had viewed this deal many times and scratched my head and then I decided to take the plunge with my old board and chip struggling just to boot up.

I got the purchase home after a great experience in the show room looking at many other things I couldn't afford. I opened all the boxes to see what you get, and what a delight, the Z170 board is a thing of beauty, i am aiming to build a black and white rig and this all black board does the trick perfectly.

I am an experienced PC builder and the build was very straight forward, loving the DDR 4 Fury Black (Again suits my rig.)

I never used the Kracken 2 as I have a Corsair water cooler, I will keep the cooler as a backup.

I am currently running this setup at 4.5ghz and it runs like a dream as if it wants to be pushed more, under full load it maxes out under stress tests at 48oC. The only thing I would say Is i struggled to find the BIOS updates on the forum, but they are there on about page 8 of the thread.

Thanks Overclockers, you have made me a very happy man, and now somewhat addicted to pushing my PC and my FPS

Excellecnt basis for a quiet system

This is a good system and very easy to put together. You do need to read the forum links about how to set up the overclocking and realise that if you do you cannot use the integrated graphics on the i5 6400 and also that it is possible that a Windows Update MIGHT disable the overclocking (you can avoid this by doing the windows updates manually and not installing any "CPU microcode" updates)
I have not overclocked the system yet (as it is already so much faster than my old system) but I have downloaded the firmware update needed and stored it safely (Intel may crack down on this being available- the provided link doesn't work any more but there is a link toward the end of the forum discussion that works).
The provided heat sink is large with a large, very slow spinning fan. Together with a be-quiet 600 Midi Tower Case and a be quiet pure power 9 500W PSU I now have a PC that is absolutely quiet. Remarkable!
I've also fitted a 256GB Samsung M2 PCI drive (SM951 256GB M.2 PCI) directly to the motherboard which was recognised on installing Windows 10 and is the boot/OS drive.
A very good system and the support from OC seems excellent. On the forum there was somebody that could not get the overclock working. 8 Pack arranged a return and sorted it out for him- Now that's what I call service.

Cool and fast

23°C idle - the Brocken 2 is big and efficient. Motherboard profile provided in the forums, easy to apply.

Fast and stable. Great value for money bundle.

Ryan 2016-02-15


using the exact 8pack settings with an aero 500 case and 2 x 120mm intake fans at bottom of front panel the brocken fan pushing air through brocken towards the back fan and the back fan exhausting, with thermal grizzly as the thermal compound, I have this at the 4.4 ghz and it idles at 28c and while on load at 100% for long doesnt go over 45c, so i think even without the water cooling this could easily hit 4.6ghz and never pass over 60c temps..... id be interested to see if 5ghz can be done within this temp range with good cooling, i think it wouldnt be too hard to achieve.

Working well.

100% stable for 2 weeks so far. Worked first time, no fiddling.

Brocken 2 is big, check your case can fit it. Works well and v quiet too, the mounting is not the easiest though. Runs ~50C under load @4.4.

Apart from Windows Sleep not resuming, lack of power management has not been an issue, Skylake is low power anyway.

Excellent price/performance overall.
