i7 8700K, 8600K, 7700K Overclock results

[Vario]

Then why does your sig say 4.8 @ 1.2v?

That was what I was running when I entered my system specs. I have left it stock since I cleared my CMOS a week ago and to be fair cannot tell a difference.

Hahah OK. But but but 5 Ghz and you must delid or nub

Nah in all fairness I think overclocking in essence is finding some optimal form of balance, ie conservative clocks at a very low vCore is IMO a greater OC achievement than just pushing max volts and seeing what u get. Some people think otherwise ^^

I can run as high as 5.1 but it is a dramatic increase in voltage and temps for just about nothing. I have not bothered to stability test for anything higher than 1.25V vcore because I do not want to put wear on my processor, which as a result pretty much keeps me in the 4.8 range which requires somewhere between 1.168 and 1.21 vcore I mentioned some of my settings earlier in this thread. I have also had decent ram overclocks but that too is stock now I really cannot tell a difference for what I am doing , but I run a mere 1440P 60HZ screen, maybe that is why. The PHTC14PE with TY143 fans has helped a lot with temps actually. When I first overclocked I was running a mere PHTC12DX.

Yes its safe to say that even at stock both 8600k and 8700k have loads of headroom. Even for 120 fps on most games - with faster RAM that is. Speedy RAM is quite huge on CFL.

Samsung B dies are a good idea if you can afford it. Cadaveca has shown that 3200 CL 14 is the sweet spot.

It's true. Don't have to have the "Intel" branded one's, though you get a better heatsink for the money with those. I'm using G.Skill Flare's for AMD in my rig. Does XMP 3200 CL14 no sweat. I just want to find another set now.. That isn't $250 bucks on Newegg...

Another set for 32GB? Might be best running 2x16GB instead of 4x8GB. I have same GSkill ram as you, though branded with TridentZ

this is afterburner from running GTA5 for 30 minutes or so with a 4.4Ghz or 4.2Ghz (i dont recall TBH) , but it handles it no sweat. great chips, stock or OC'd.

Spoiler: afterburner

40% usage cap Yup. But this is 60 fps is it not?

 

[radrok]

I kinda agree with the statement that delid is not mandatory, as I said I am achieving 5,2GHz with 1,36v and not delidded.

Only getting insane temps when stress testing but that kind of load never happens on normal usage so my CPU stays around 50-60c at that speed.

I have a delid kit here but why should I delid? For higher clocks? Don't think CFL can handle 5,3/5,4 daily tbh

 

[EarthDog]

I wouldnt due to where your voltage will need to be for stability.

 

[radrok]

On the other hand I think I will fiddle with memory more as I think more performance can be achieved there.

I am currently running 3600 c15 with recommended voltage for these DIMMs but I'm pretty sure C14 3600 is doable

 

[jboydgolfer]

yeah, i have a 60Hz Dell, so i run 60Vsync. ive uncapped it, didnt do more than another 10c @ most

For 3200MHz it shouldn't be a problem.. even up to 3600-ish. I have another set of RAM, different IC's that work with this set at 3200 cl15.

 

[jboydgolfer]

I didnt have a cap set on usage,it if thats what you mean, it just doesnt need more. I turned off vsync, and let it run up to 180'ish fps, I also set afterburner to display the frequency of the CPU. And for the intel temperature naysayers ,this is my cooler and fans "silent" preset. Running almost inaudible

You can see with vsink disabled , The temperatures reach up to 45-ish, and CPU usage jumps up to about 85%, but normally rests in the 50c mark. Also, isnt the AVX thing used when in gta5?

 

[Vario]

Is anyone here running microcode 84? What are your observations? I just went to it myself and it seems about the same performance as far as I can tell, though I am noticing my processor never seems to get over 4239 Mhz in stock bios settings.

 

[FreedomEclipse]

My 8600k is on its way....

 

[Darkfella]

Those are the temps for my delided i7 8700k . Before delid i was hitting almost 70 c when the weather was colder , now this is during a hotter day. I'd say its pretty good decrease at around 15 C. CPU is overclocked at 4.8 with adaptive voltage of 1.220 LLC5 on a Maximus X hero.

 

[deadend]

I have my i5 8600k @ 4.7GHz 1.280v cooled by an Arctic Cooling Liquid Freezer with the following temperatures:
under 60C while gaming
CPU benchmarks 67C
prime95 small fft 77C after 1 hour

the temperature differences between cores is 1-2C

It also works with 5Ghz @ 1.330v, however temps are around 5C more and in my opinion not worth it.

I believe I got lucky with the CPU lottery and the Malaysian dude who placed the thermal compound under the IHS was on a good day and put enough.

Opinions? Would delid/relid make a difference in temperatures?

 

[radrok]

After tinkering and delidding I settled for 5,2GHz at 1,425v under load and CL15 3733 RAM

Have to say that this is my first MSI board after owning every ASUS Rampage board since the first one and I found it at the same level of quality.

1.425 for 24/7?

I take it you don't keep this chip for more than 3-4 years then... because the likelihood of having to add a volt or drop a multi by then is quite high at that voltage. Regardless of temps

 

[radrok]

Dunno tbh, kept many Intel chips for years at what people considered high for 24/7 and they still work and didn't even need more voltage to stay stable during the years.

Ran an i7 920 at 1,5v never had an issue, same for a 3930K that did 5,1GHz at 1,52v, 5960x etc they all still work.

 

[Vayra86]

Well I hope this one treats you as well as the others then Its a badly documented thing, degradation, but in your situation I would personally find a more comfortable sweet spot, I mean its highly likely that dropping a multi or two will drastically lower the required volts and take you into safer, cooler and much more efficient territory. But of course, 5.2 is a very nice clock to have too.

I may also just be too cautious about this, but then again I've also not blown up a single CPU yet

 

[radrok]

These are the temperatures during AVX load

third column max temp

Anyway you're right that dropping to 5,1ghz i can reach stability with 1,34v

Probably will drop your temperatures a few degrees but it won't make your pc run any faster so why undergo the bother?
