Title: Overclocking
Post by: Phil.8 on January 10, 2018, 02:11:23 PM
Grat got me thinking about overclocking.
I have a gigabyte z170x gaming 6 and a unlocked 6700 cpu, in the bios in easy mode there is a way to overclock by picking performance over normal or eco,  this give me 4.3 ghz at 1.272 volts and about at idle 23 degrees core temps , 30 package temps and 27 on the corsair cooler temps.

I am sure this is not this is not the best way to OC and I have no experience with these newer cpus, Last time I overclocked it was a like a i7 940 and before that years and years ago old amd processors and I think the process is easier these days, I am just not sure where to start.

Do I just leave in performance mode  or go back to normal and boost the multiplier or use the cpu upgrade overclock setting or performance upgrade option with five different presets  of 20%, 40%, 60%, 80%, and 100%

I guess I am asking if anyone with OC experience can tell me the best easiest process :)

I have tried the cpu upgrade option and running at 4.5ghz at 1.272V   does that seem ok ?

That's ok, I need 1.4v to achieve 4.7 on my 6700k and have been for a while.

Funnily I've nfi what the mobo  is doing, but I'm running a 6700k at 15% overclock with ASUS' single-click overclock (or whatever it's called).   So it just did its magic, restarted a couple of times, and settled on this value - which is a respectable 600MHz over stock.     I think this is the future of the consumer-level o/c.  Enthusiasts can do whatever magic they want, I'm happy with this result, hehe.

 best I could manage today with it being stable was 4.3, I only used the bios easy overclock options,  I was thinking of only getting a bit more life out of my pc in the future and I might try manually tomorrow as its a bit of fun to see what can get to while learning how it all works.  But for peace of mind and easiness I will probably just buy a new pc or at least mobo, cpu and ram instead when I deem this one to slow

Depending on your chip you should be able to get around 4.6 @ 1.35v, as bird mentioned his asus board auto overclocked to 4.6. My asus board did the same but it set my ram to 2933 instead of 3200MHz, so I manually overclocked 4.7, 4.8 requires 1.5v and gets warm even with good cooling. I've managed to push ram to 3466mhz. The way I see it is we bought the unlocked cpus we might as well push them...if it dies it's a good excuse to upgrade lol, the reason I don't mind pushing my voltage high. Performance gains even small ones are still gains lol
Off subject how's the monitor shopping going?

I just tried 4.5@ 1.35v and instant blue screen in prime95  took 2 seconds to bsod, My ram is in XMP at 2666MHz, not sure if that would be causing it to bsod,  I guess I was not lucky in the silicon lottery

I am thinking of buying this instead

Overclocking my style   just buy new faster stuff :)

would of been cool to get a decent overclock just so I could say I have done that now, but it seems a lot of hassle

Prime will be hard to pass, look for a setting for load line calibration (llc), could be called something else in the gigabyte bios. Under heavy work loads like prime the cpu is designed to lower the vcore a little, llc can counter that. Or you can add a little more vcore to compensate. If you can achieve 4.5ghz then you will have a cpu identical to the 7700k, so it's really a bit of a waste to buy one, except for the possibility of a 7700k overclocking higher. We'll only need to upgrade if we need more cores or if a significantly faster cpu is released imo.
Does your cpu run the h264 test from overclock. net at that setting? BSOD is nothing to worry about, windows telling you there was an error that caused a crash. If you are someone who likes to tinker then overclocking is a bit of fun, if not then it's probably just a headache lol.

Do you man disable llc or what do I do with it ? I have not tried h264,  but Battlefield 1 would not load for 3 times and on the 4th time I tried to launch it I got into the game but bsod within a minute

Adjust llc, should have a few steps, some boards are backwards compared to others. My asus board has 8 steps and I need llc 6, on asus higher means less vdroop under heavy loads

None at all.  Overheating can.  But Intel chips are very sturdy, not just tolerating high temps, but also safeguarding against overheating.  There was a guy who tried to fry chips, and he simply could not kill the intel chip.  He succeeded with others, though :)

If you buy a 7700k, you'll be able to run it at 5GHz!  ;)  (but you won't be able to run win7 without much hassles!)

If you buy a decent asus board, you'll prolly be able to do that with one click, too :D

Ok I have read all about vdroop and understand now.   My board only have auto, standard and high for my llc settings,  I am searching the net but cant find much on it for my board, gigabyte z170x gaming 6

From memory, I think auto is off (Intel's design), standard is a little bit and high is high llc

so would a good start be 4.5@1.300 with standard llc do you think ?

Sounds good, just keep an eye on cpu temp and vcore (not vid with skylake) with some good software like hwinfo64 - sensors only

My brother is on the lookout for a new monitor too and I recommended the MSI as well as others, looks good. The asus though, I don't think has vesa mount, I have a 1080p version for my daughter

I tried this with standard and high llc and went up to 1.35v   , still blue screens and games wont launch or if they do they blue screen after 1 min max. the blue screen is always clock watchdog timeout.
I came across this thread, which decides this is not a good board for overclocks and requires a slightly different approach. Post 5 is the interesting one.  I have not tried it yet as I am not sure its worth the bother. I can get to 4.3 ghz easy but any higher it blue screens, and .3 does not make much difference , I really just think I lost the cpu lottery

That post you mentioned sounds like it'd help you a bit for that motherboard. You can try manual/fixed voltage first to see where your cpu stands then dial in the dynamic voltage. Low voltage will most likely be the cause of the bsod. Try to keep around 1.4v maximum so long as the cooling can cope, around 80c max is ok. The asus board is pretty good, heaps of settings, but still a pain to work out at first. Not without problems though, different bios versions had different bugs or broken things. This guy uses a gigabyte board https://youtu.be/CV-J2TU08Qk

I watched the video and tried what he did by doing just the multiplier at 44 and nothing else which according to cpuz was running at1.28V and got to 64 degrees. I got about 15 mins of prime95 before it blue screened

64c is good and gives you extra headroom for more voltage. My chip is below average, it needs quite a bit of voltage, hopefully yours is better. Start with a manual voltage of 1.375 and multiplier of 43 and increase one step at a time until it crashes then back off one, keep ram at default 2133 at first only and only apply xmp after you've found what your cpu can do. Like me you might need extra voltage on vccio (cpu memory controller) and vccsa (system agent) keep those at a max of 1.2v. See how that goes, if you find a multiplier stable with manual voltage first, then you can try the dynamic voltage with the same multiplier. Have you got the latest bios version from gigabyte a lot of early Z170 bios' were buggy. My vcore is 1.4v but is actually about 1.44v because of the higher llc I'm using, my vccio and vccsa voltage are 1.25v. I've bumped up ram voltage to 1.39v so I can clock it higher than xmp.

Don't fuss too much, Phil, you haven't lost any lottery.  You have a chip that overclocks from 4GHz to 4.3 - that's  7.5% free powah :)
Some chips are indeed a bit better, some boards are better (at o/c), but all in all, you still got a bit extra.   It wouldn't make too much of a difference to get another 200MHz imo.

Prime will run hot and the load fluctuates a bit, so you might get a high maximum but the average will be lower, games won't be that hard on it temp wise.

I also notice cpuz says voltage a bit lower than what bios is set to, like when set to 1.350 in bios it reads 1.320 in cpuz

Currently testing 4.4 with 1.300 in bios which says 1.284 in cpuz with temps max at 83 and llc on high

How long is long enough on prime95 ? been 45 mins with the lower voltage so far, I think changing the llc to high has helped the most

That is normal for some motherboards, particularly one's that don't have as granular llc and other settings. Some people say 5 hrs some say over night, but I am pretty sure if prime is going crash or drop a worker it'll do it within an hour or so. Real world usage is going to be the main test anyway, or do the h264 test for an hour since it's probably a bit closer to real world usage and realistic temperatures.

I used prime95 with hwinfo. It all goes "low" temp until the 8 tests end (say high 70s to low 80s. As soon as they end, hwinfo shows the temps to jump up a lot, approaching 99C... I was pretty confused and scared by that. So I stopped prime95 and the temps went instantaneously to 45C or so. Do you know what that means?
