Final Gigabyte 8700K Test System and Overclocking Results

2018-06-14
welcome back to hardware unboxed a couple of weeks ago you might have seen my livestream on the channel our first ever live stream where I built a new test system with help of Intel gigabyte and pasted case gear aside from a few technical issues the stream was a ton of fun and I hope all those that watch live to chat with Steve and me had a blast anyway in that stream I only showed the completed build briefly and didn't talk anything about overclocking results or anything else to do with performance because I simply didn't have time to get into that on the stream but in this video you get to see the finished build with respectable cable management unlike the version I showed on the stream and I'll discuss a little bit about the overclock I managed so basically I built the system for testing various things on Intel's latest coffee-like platform I already built an AMD test system several weeks ago complete with the rising 720 700 X and a brand new gigabyte OS X 470 motherboard this latest build is essentially an Intel version of that so now I have both an Intel and AMD build with the latest parts from both companies expect some exciting game testing for me when the PC release season kicks back into gear in a couple of months the key component in this build is of course the Intel Core i7 8700 K until provided us with this trip directly as a retail sample so it'll be interesting to see how overclocks and whether this is a golden sample considering this is just a simple sealed retail chip rather than an Intel QoS chip like they usually give out for day one reviews I'd add will be anything special but we'll certainly find out later the motherboard is gigabyte z 370 horas ultra gaming Wi-Fi with 32 gig of integrated octane memory gigabyte do offer a version of this motherboard without obtain and at the time of the livestream the octane version was just 15 dollars more than the non obtained version which I thought was a pretty good deal especially for those building a system with that ultra-fast nvme SSDs right now though the optimal is 50 dollars more than the standard model through Amazon which is much closer to the optimal $57 sale price the octane board is definitely harder to recommend at that price I'd probably wait until it gets closer to that $15 price difference again but those that straight-up don't want octane can get every other feature of this board in the non obtain aside from obtain this board does provide a ton of RGB like ludicrous amounts of RGB even for things like the PCIe sockets and DIMM slots and what appears to be a four plus three-phase vrm solution with heat sinks slotting into this board we have team groups T force Nighthawk RGB ddr4 memory a 2 x 8 gigabyte kit with ddr4 3000 speeds and their unique heat spreader design looks pretty good here although it was a bit of a challenge to sync up the RGB effect using gigabytes RGB software it seems to work some of the time which I guess is good enough though it's not something I'll mess around with too much for just a test system for cooling we have to be quiet silent loop 280 which should provide enough thermal capacity for a respectable overclock of the 8700 K I installed that in the front with an embarrassing amount of difficulty so go back and check the stream for some awkward issues there entirely my fault there the cooler is actually quite easy to install if you're not a dingus like me anyway everything i've just mentioned is installed in another be quiet product the dark bass 700 which are quite liked with its psu shroud RGB lighting on the front and tempered glass side panel there's also plenty of room for cable management on the rear so there wasn't too much drama shoving all the cables into that space and forgetting about it the case also comes with a fan controller which is pretty neat the cases rear fan is a basic affair so I added some bling to it with fan takes 140 millimeter halos which since the stream have actually gotten working a pretty neat concept if you don't want to pay for RGB fans and just want to use your existing ones the SSD is also RGB if you can believe it take a look at the team group delta r gb SSD which on their website they call the magnificent version it's a basic 256 gig sided drive but the cool feature is its massive RGB panel on the front there's so much RGB here I just had to tape it to the inside of the main compartment of the case but I can't mention while building the system the drive doesn't matter too much in a test system as we already have our standard test system drives so this silo model will be fine for now hidden away under the shroud is a new power supply from be quiet the straight power 11 650 watt which at the time of the stream didn't even have a picture on Amazon it does now though and it's a neat fully modular unit with an 80 plus gold certification and of course the GPU which you will be familiar with if you saw my AMD test system built its the gigabyte geforce gtx 1070 TI from that bills my md test system is currently loaded up with ave 256 cards so i have been 1072 i spare and made sense to chuck in this system for now so you've probably seen a ton of b-roll of the build by now and i reckon it looks pretty awesome for a test system that RGB SSD in particular just adds to the craziness inside big thanks to Intel gigabyte and PC case give helping set the system up if you're ever interested in what Intel system I'm using to tester this is it in terms of overclocking I've been messing around with the system over the last few days and it seems this 8700 KS one that reaches 5 gigahertz reasonably easily but cannot push up to five point one gigahertz at least on this board with this sort of cooling achieved 5 gigahertz just using gigabytes auto voltage and auto LLC options with voltages hovering around the 1.39 to one point for one volt mark CPU temperatures were just above 90 degrees Celsius and vrm temps they were a bit toasty in the mid 100's as well under an IEEE 264 stress test five point one gigahertz though was problematic I couldn't achieve it with auto settings and pushing LLC settings to the max and shifting voltages up to one point four two volts just didn't do the trick possibly running into a heat issue there with 5.1 gigahertz that Adi later might solve but that's not something I'll be doing here in any case I wanted to achieve 5 gigahertz and I'm happy with that but this retail chip definitely isn't a golden sample by any stretch I might even push the system down to 4.9 gigahertz to ensure top-line stability and keep temperatures and even better level I have to keep tinkering with the system over the next few weeks to see what it can do anyway that's it for this recap of my latest Intel test system if you're interested in the part seen in this video there are links to all of that in the description below don't forget to subscribe for more hardware unbox content and I'll catch you in the next one
