excellent hey guys Paul here welcome back to Pauls hardware today i have a sort of a different kind of video if you guys recall perhaps recently I did a couple videos unboxing the Sabre to the 87 and these 87 pro both motherboards from Asus z7 chipset 1150 socket for Intel's Haswell processors now I asked y'all for some advice or some suggestions for what type of coverage you might want to see with these motherboards and I will say there was lots of requests for a build that's what I'm going to be saving the sabre-tooth z87 for so this is going to go in a full system build which I have yet to part out that's a future video so I'm going to set this one aside for now today's video is all about this one this is the 87 pro now another request I got a lot of requests for was overclocking of course because that's a hugely popular subject particularly when it comes to building computers building your own computers building a high-end computer all you really need is a case cube processor from Intel right now for as well you got the 46 70 K which is the four core no hyper threading or you have the 4770k which is four cores with hyper-threading so 4 physical cores and 8 logical course yeah okay so the z87 pro from asus features there are four way optimizations so this is that's that's what this is right here dual intelligent processors it's their TPU chip and their epu chip TPU chip handles some overclocking algorithms and presets and it can auto tune your your motherboard for example you use for energy saving four-way optimization goes through TPU e pu fan expert and then there's one last one which I will correct myself on in just a moment but it does all that stuff and you click one button and it goes to an automatically tunes it all now I view this from kind of a couple different perspectives the the enthusiast in me says well that's cool and all but I don't want some automatic overclock I want to get in there and adjust the settings myself the pragmatist in me says that's awesome it's really easy you click one button and then you have an overclock now I have been doing some testing with this already so I can't tell you guys the overclocking features the TPU chip are quite effective they might not be as fine-grained as a lot of you might consider especially if you've done overclocking yourself in the past but if you want to really quickly dial in a pretty high-end overclock it's a very effective means of doing it so with that long intro out of the way this video is going to be all about the 4770k and overclocking using four-way optimization from Asus but more specifically I'm actually looking to get a little bit of benefit out of this myself if nothing less than to help me out with my work over at new ITV to that end we have a set of 4770k CPUs in right now which are going to be used for a variety of purposes but primarily for builds and maybe some giveaways and I I was like hey I wonder how these perform because I've heard there's a huge variance in 4770k s or maybe not huge but there's a pretty big variance you might get a chip that can overclock a little bit and maybe you can get a little bit of memory overclock you might have other chips that can do both like really high-end getting one that can do both seems to be a bit harder to come by but there seems to be like you might get a chip that can only clock to like 4.3 or 4.4 and then you get others it can do 4.8 and then you might have different memory frequencies that they accept in between there so I'm going to be using dual intelligent 4 processors and the four-way optimization features of this board to test one two three four five six and seven in sell cry 74770 KS so with that said I guess so let's just take a dive in we'll take a look first at the test bed and my methodology for running these overclocking tests so here is a look at the test bed it's a Leanne Lee T 60 B that's the testament itself of course motherboard the asus z87 pro as we've been looking at and for the processor of course the intel core i7 4770k seven of them in total and I'll be swapping them out throughout the course of this test for cooling we have the thermal take water 2.0 extreme which does a fine job for memory I actually have a couple kits one is a corsair low profile 4x4 gig ddr3 1600 kit and I used that for my initial set of overclocking let's four-way optimization and then I also have a g.skill trend an X kit that's for also by four by four gigs ddr3 and that's a twenty six sixty six and the four way optimization will overclock that to twenty four hundred speed for video card just got a ZOTAC GeForce GTX 550 ti in there so that the processor won't also be pushing GPU duties for storage of course Aaron Neutron GTX 240 gig I'm running Windows 8 and for power and an tech hiker high-current pro 1200 watt as far as testing methodology first off if anyone is planning on doing this I definitely recommend saving a stock configuration profile it's an option in the UEFI BIOS just go ahead and do optimize defaults and then save that so you can jump back to it whenever necessary so basically after each CPU is installed I'm just doing a quick 30 minute I'd s-64 burnin as well as a rest period and then of course starting out for the corsair 1600 speed ramp after that I've run the forward optimisation test and log the results and that's basically seeing how far the CPU can overclock while the memory stays capped at 1600 I then am running past mark as a stability test if you're wondering why I'm not running I 264 something like prime95 it's because those types of programs apply an additional amount of voltage to the fourth generation has well processors which you will never see in any other test anyway after that I jump in and install these g-scale 2666 speedram around four-way optimization again and that will put the memory at 2400 speed with the CPUs if the CPU stable at that speed I go ahead and set the memory to 2666 the top speed it can go and then I run past mark again if it hits all of these points then I run an Ida 64 burnin test just for five minutes because again these aren't my CPUs but I do want to see if they will maintain stability and there we see some pretty high temperatures depending on the overclock we also see additional voltage that you won't see with any other tests except something like Ida 64 or prime95 let's take a look at CPU number one now this is my engineering sample CPU and this was described to me as a middle of the road when it to overclocking CPU when it was lending to me pretty much as expected it hit about it hit 4.4 gigahertz on the initial overclock and 4.3 gigahertz on all four cores so you'll notice when it's doing the forward optimization it'll go for a higher overclock using just two cores and then if it achieves that it will go for that overclock with all four cores so sometimes we'll see all four cords at the same frequency sometimes we'll see two cores at a higher frequency and all four cores at a lower frequency the voltage was at about one point two seven after that I went ahead and ran past mark got a score of 4728 on the voltage again one point two seven three on this one with the four point four gigahertz overclock so pretty decent performance there next up I went ahead and I ran the g.skill memory so that got a 2400 speed again 4.4 gigahertz and 4.3 gigahertz with that configuration past mark test actually dropped a little bit I'm not sure why that's allowed four thousand six hundred and eighty two but apart from that we also set the memory to 2666 was also successful there so that passed mark rating was four thousand nine hundred and forty three point six and pretty much a nice decent overclocking cpu this engineering sample 4.4 gigahertz on two cores 4.3 gigahertz on four cores and it did also survived the I 264 burnin test although the vid did jump up to 1.3 eight CPU number two was an individual CPU it didn't come in a group like CPU number three through seven and this one was actually the lowest performing and also a bit of an anomaly with this one first off when it did the initial overclock which for the for baptism optimization is 4.3 gigahertz on one and 2 cores 4.2 gigahertz on three cores and 4.1 gigahertz on four cores it wasn't actually even able to remain stable at that speed so I got several blue screens after the initial restarts once the test ran I actually had to jump into the BIOS and I applied an additional voltage offset of point zero seven five which wasn't that but it did stabilize the overclock and actually after doing that it was able to overclock up to four point four gigahertz and four point three gigahertz which is again a decent overclock kind of like the engineering sample it was stable at that speed I got a pass mark score four thousand eight hundred and fifty four however it did maintain instability when I popped in the G scale memory so at 2400 speed I was able to run through the pass mark test and I got my score four thousand seven hundred and thirty-four however there was instability there so due to that I did not go and run the additional tests at 2666 so again this was the lowest performing the CPUs and without some additional help from an additional voltage it actually only hit four point three gigahertz next set I'm going to go through a bit more more quickly because the next five CPUs are the five that all came in one big batch so they were all CPUs right next to each other and as a result they held her for Mary very similarly so starting with CPU number three this was the first one I popped in and I my job just kind of dropped because it just kept going I went to 4.5 4.6 4.7 and eventually hits 4.8 gigahertz on two cores 4.7 gigahertz on four cores and when I went it with 2400 speed memory it did need to drop it down to 4.7 gigahertz on two cores and 4.6 gigahertz on four cores but again still past past mark with that five thousand five five thousand 53 was a score and then that with the 2666 bead memory hit 5133 which was very nice the luck did continue with CPU number four that one hits not quite as high for point six and four point five right off the bat but it was able to maintain that even with the 2400 speed memory and again very nicely performing CPU and you might notice here again the voltage still just hitting about one point two seven that seems to be the theme than the voltage amount that asus is going with pretty frequently with the there there forward optimization software I did run through this all the way and do the i-264 burnin test so even at 4.6 gigahertz on two cores four point five gigahertz on four course with the 2666 speed memory and I had a 64 burn and tests did pass so a nice solid CPU their CPU number five was a big hit once again and was another one of our four point eight contenders so four point eight and four point seven was the initial results for four two and four cores respectively had a really nice score of five thousand forty which I think was one of the higher scores for the eight hundred frequency memory with the twenty four hundred speed memory I did drop down to four point seven and four point six and then when I did drop in the twenty six sixty six feet memory it did still may maintain stability there however with the Ida 64 burnin test the vid jumped up to one point three three two it did get very hot in fact I had a hundred degrees Celsius on three of the four cores and so CPU throttling did take place as a results maximum was only eight percent but still it was getting a bit too hot so that's another example where some system testing does just play a part and I definitely would have backed off the overclock on that again this was only using the Ida 64 test it was just fine using the other tests but and that was also with the 2660 speed sixty six speed memory CPU number six dropped just a bit four point seven and four point six was the initial testing after that we hit four point seven and four point six with a 2400 speed memory got a nice past mark score five thousand one hundred and twelve and then after that with the 2666 speed memory still passed the pass mark test and also the Ida 64 system stability test and finally we have CPU number 7 CP number seven was a little bit stranger because initially I got four point six and four point five with the initial tests and I went ahead with that because it's still a very nice overclock but then when I jumped up to the 2400 speed memory it actually the frequency went up as well so four point seven and four point six with the 2400 speed memory so I just said okay let's run with it and try the 2666 speed memory there I did still pass the pass mark test with a score of 51 27 and I did pass the Ida 64 test however I did I was hitting about 95 to 100 degrees Celsius on the course so that's something where I definitely would have backed it off a bit just if I was going for a more stable overclock or an overclock that I wanted to leave for a longer period of time so in closing I would have to say that I was actually very impressed with several things as throughout the duration of making this video first off the forward optimization very very well tuned I must say the voltage was not it seemed a little bit more standard to me it didn't seem like though it was making voltage adjustments too much but they were putting in what seemed like a safe voltage and then they were seeing what kind of frequencies the CPUs could get up to after that honestly I didn't have that much time to play around with each configuration when the CPU was installed because I was trying to get through them all so I didn't really have that much chance to go through and try to tweak the other settings manually on my own but what I did try I found that the frequency that the forward optimization was able to get to was pretty close to the to the peak frequency I mean I know some some exotic cooling some higher-end cooling like a custom liquid cooled loop could probably get you that further than that or fickle exotic lowing or something like that or some really extreme cooling on the VRMs with fans or something like that you could probably go higher you can probably tweak the the voltage a bit more yourself if you are going to use this that's one thing I'm going to try to do is see the lowest voltage I can get with some of these overclocks but at least from a quick and simple way to take your UK skew processor click a button see what kind of overclocking get and for this purpose it was extremely effective at seeing the peak frequencies a lot of these processors processors were able to hit a couple more closing remarks I am absolutely stoked by the group of CPUs that we got they they came to us in a batch of five and those as you might have noticed they're all from the same batch so chances are those are all from the same wafer so the ones we were getting for point eight four point seven on those are all grouped kind of close together the other two CPU number one and CPU number two one was an engineering sample number one was and CPU number two was from a different batch so wasn't performing quite as well I also need to point out that this is a very very small sample size when it comes to the total number of 4770k s that are out there so please don't take this to be a blanket like you know to 70% to 4770k should be able to hit four point seven or four point eight right out of the gate that's probably not going to be the case but I'm really happy to say that we have some nice overclocking chips here that we can try out ourselves for future benchmarking and stuff like that over on nuoc TV so more of that I'm sure will be coming as soon as we can get the videos created but I had better sign off for now once again we've been taking a closer look at the N cell 4770k and its overclocking potential its potential its overclocking potential the like button of course right down there in the lower left corner go ahead and hammer on that for me if you guys can and that's gonna wrap it up for this one guys thanks for watching we'll see you next time
