[6700K Silicon Lottery] Is your CPU a Golden Chip? How far can it go?

Out of curiosity, could everyone share your Under Volt, Max OC and Package Power numbers?

Run OCCT for the CPU stability test for at least 30 minutes.

*** Please post stable clocks only and not under volts or OC's that will only last a few seconds before locking up. The Package Power will fluctuate a lot in patterns so please try to obtain a solid average to the best of your abilities or just state, "Low 90's, Mid 90's, or High 90's etc..." ***

hoping there will be a lot of attendance here, would be curious to see overall results im stuck at max. 4.3 Ghz with CLU and 4.2 Ghz non-metal paste with my 4790K in OCCT. thats integrated FIVR for ya.... max attainable stable is 4.8 ghz, just that thermals dont play along so in a desktop this would be a nice chip

btw, u already have those 960 pros installed or waiting for delivery? seems a tad early for consumer hand-on...

 

My 4.8 GHz rated SL CPU can do 4.6 GHz stable in my laptop. The rating they give a CPU is done on a desktop which has better cooling

 

Aestriks

Ah, 4790K...the classic beast.

::iunlock::

 

I have been running 4.6Ghz for benchmarking at -30mv and 24/7 -60mv at 4.4Ghz.

So not bad but not amazing.

 

Very nice. Are you able to stretch that -30mv any further at 4.6GHz?

So far I'm able to push it to -55mv @ 4.6GHz with it being stable.

At Stock clocks it can go to -225mv on both Core and Cache.

 

No 4.7ghz crashes and upping the voltage to around stock or higher makes it thermal throttle.

 

How is the max temp and score in Cinebench R11.5 and R15 with 4.6 GHz? I expect You have 4.6 on cashe as well. Higher cashe ratio... more heat And what is your base voltage?

 

I'm running OCCT right now(Stock Clocks and Under Volted -225mv) as we speak with F1 OFF on the stock fan profile:

CPU Temps: 67C, 67C, 67C, 64C ....Again F1 Fan Profile OFF.

Under Volting the CPU is mandatory.


Impressive...

I haven't really focused too much on Cinebench, although I did run it a few times. But here's a run I just did now....Temps are great.

@ 4.6GHz




@ Stock Clocks


Ambient Temp:

 

Cinbench R11.5 and 15 is fine benchmarks and Nice max temperature But how much higher will it be with 4.6 GHz on Cashe? I would expect the temp will rise up a bit Also Max temp will decrease a good notch down with your 225mv under volt and stock clockspeed.

 

Hmm that's strange, the core cache is set to 46x in XTU...

Even in BIOS



Ah Okay I've found the issue...as we know XTU and Throttle Stop don't like each other. The profile from TS was conflicting with BIOS presets.

The Temps are a little higher, but still very good.

 

Yes the temperature is nice But now you have an increased voltage. Why? Thought you run around 1.280V and not 1.336v for 4.6 GHz. This is about the same voltage as I use for 4.8 GHz on cores and 4.6 on Cashe.
http://forum.notebookreview.com/threads/clevo-overclockers-lounge.788975/page-243#post-10259419

 

I didn't open TS this time so the profiles likely did not load, therefore it was maybe on stock voltage? I'm thinking so...either way, that makes the temps even more impressive if you ask me...

Right now I'm tuning to get it to 4.8GHz....it'll stay alive at those clocks, but right now it's still current limit throttling and likely thermal limit throttling, although it doesn't show on HWiNFO64. That doesn't mean that it is not though so maybe a little more time with it and hopefully I'll have a stable 4.8GHz? We'll see... 4.6GHz is plenty though and I'm very happy to have that as my daily driver.

 

You have fine max temperatures in bench. In daily use, you're not even close to max out your processor like CB. And 4.6 / 4.7 or 4.8 GHz don't have any huge impact outside benchmarks Around 4.6 GHz is a great result for the vast majority with a good silicon and paste in a laptop. Many run at a lower clock speed than this and can't reach 4.6. Even a lot of owners run stock clock speed And worse.... Run stock clock with 6820BGA

 

Yea I feel lucky to have have a good chip. My GPU not so much I can't even get half the OC that other fellow GTX1080 can, but it's been pulling in some pretty good bench numbers.

Right now I'm tuning for 4.8GHz and will see if it passes OCCT Test.

Out of curiosity, would this mean that my chip being able to run at 4.6GHz stably is like me buying the 4.8GHz off of SL for $430? Would you consider this winning in the lottery?

I'm curious if others can run it at 4.6GHz with -55mv. Can you guys confirm?

Thanks.

 

Most 6700K can do 4.6 GHz in laptops with decent voltage. But your chips are good and there is no certainty, an SL chips would work so much better. There will be something else if you used it in a desktop. I'd say you have a good chips. Have not seen SL chips make it so much better than stock retail chips in bench... Rather the opposite

Spoiler: I haven't SL chips, just an ordinary one :|

 

Poor saps to who buy them then eh?

I'm curious to know how much of an under volt members are able to get at 4.6GHz. Also, how high of OC they are able to run stable. What are you 4.6GHz under volt look like? 1.191V? Lower?

For 4.8GHz, mind sharing your Voltage and Core Voltage Offsets? I've been tuning mine for the past couple of hours...It holds at 4.8 pretty strong, but then at random it would lock up. Sometimes after a while of intensive tasks etc...everything is fine for a while, then out of the blue, locks up.... It may just need a minor adjustment for it to run stable.

As for 4.9GHz OC, any ball park Voltage and offset figures to start off at? Trying to see how high this thing can go!

 

4.6Ghz @ -70 . 24/7.
Currently using 4,5Ghz @ -84 for daily use.
Stable @ 4.8Ghz for benchmarking.

 

Excellent. Thanks for sharing! What are you temps at 4.6GHz (-70mv) ? I take it that the under volt is both on the core and cache ya?

 

Yeah, i leave the cache @ 4.3Ghz with - 160.

Temps, on a not so hot day or at work where the ambient is about 23-25C ish, are usually low 70's @ 4.6Ghz. With 4.5Ghz high 60's.
And on hot days, high 70's and touching 80C after rendering for more than 5-6 hours.

 

I would von the silicon lottery if I could do 4.6GHz with 1.194V. But no
I do like @Mr. Fox. Prefer Static voltage. [email protected] and [email protected] GHz
Cinebench with 4.6 GHz. I never bench with this low clock speed. Always 4.8 GHz. And one or two times tried with stock clock

 

Yes sir

 

I've been stretching it on 4.6GHz and got it down to 1.192V, but the limit otherwise it freezes up.

4.8GHz is almost stable...almost there....mind sharing your core voltage offsets as well for 4.6, 4.7 and 4.8?

I wish my GPU was this good...darn...

ps. Can you try uploading the pic again? It didn't show.

 

try going for static voltage instead, u could potentially achieve lower voltages than with offsets and stretch your OC further

 

I think there is a good chance your CPU is that good and the settings you are trying to use maybe not be ideal. Maybe you're just being too stingy with voltage. Trying too hard to use too little voltage is a common mistake. A lot of people are overly paranoid about using the amount of voltage necessary, and some are downright preoccupied with the concept of starving their system of the voltage it needs to perform at its best.

Also, remember that the higher the core temperature goes the more voltage it takes for overclocking. It can become a vicious circle and the key is keeping things cool. And, by cool I mean cold as opposed to "safe" or "not too hot" because you can be cool enough for 4.6GHz and not cool enough for 4.8GHz unless you increase voltage more simply because the behavior and voltage needs of the CPU changes as the temperatures go higher. Try setting around 1.425V static voltage for 4.8GHz as a starting point for testing and see if that is stable (assuming the temperatures are still controllable). Skylake is voltage sensitive in terms of behavior, but not so fragile that you need to be overly concerned about ruining the CPU with the voltage limitations of these notebook motherboards.

Indeed. Getting a Silicon Lottery CPU might reduce your chances of getting a poorly binned chip, but a cherry picked CPU won't fix wrong settings or let you use less than the necessary amount of voltage. In other words, a Silicon Lottery CPU won't perform any better when using the wrong settings. There is nothing special or different about a Silicon Lottery CPU other than it has been pre-tested and validated to be binned nicely and run stable at the overclock it was validated for. Installed in a different motherboard, using different settings, one should expect that their mileage will vary. The two 6700K CPUs that I had, the CPUs that @GTVEVO @Johnksss@iBUYPOWER @Papusan @TBoneSan @dspboys and many others have which have no problem handling 4.8GHz or more were not cherry picked processors. They are just tuned correctly to perform at their best. That said, some CPUs are binned better than others. A poor sample will never be as good as one that is normal or better than normal. The one @Papusan has is a great sample and he did not pay extra for cherry-picking.

 

I have a desktop with a 6700k, it can go to 4.8Ghz at fairly high voltages. I think I got fairly lucky with that.

 

Desktops will be more stable at the higher ranges usually due to their better cooling all around.

 

You might want to add a 5Ghz option in the poll.

 

Is that you ?... I was wondering... you bastard you

 

Whew. And here I am with my ancient i7 [email protected] stable on air! I don't even think I tuned with voltages much, just found a nice clock when I built the machine 8 years ago and never had a reason to push it farther. Seems a bit bizzarre that the newest generation processor is having trouble going past those same clocks, especially since the 6700k's base clock is so much higher. The 920's base clock is 2.66Ghz...

 

wow! what a nice CPU you have! holy moly!

 

Performance per clock is way higher on the modern CPUs compared to the 9xx generation (the 2xxx was the last big jump).

 

Here are my temps @ 4.6 GHz on all cores after a 5 min stability test with a -20mV offset only



After this test, I decided to decrease the voltage to -26mV for Core/Cache for better temps

 

cruising along at 4.5 ghz at around 1.2v Vcore, fans are dead silent, me likes stable oc is up to 4.8 ghz but im having some issue with current throttling at 4.8, no idea why though. set all current limits to max in the bios (premamod), still no dice, weird...temps are fine btw, below 90C even at 4.8. in any case, seems like my cpu is topping out at 4.9 ghz, cant seem to get it stable while staying below 1.4v (my personal limit) and 5 ghz aint possible, not even for a nice cpu-z verification, bummer...wouldve been nice all in all, im happy though, seems like a slightly above average cpu

oh btw these results are just with a repaste on kryonaut, no delidding

also, i finally got lucky with the heatsink, it seems to provide absolute perfect fit on the cpu side, yehaw! max difference between cores im seeing is like 4C, so negligible...

do you have a Silicon Lottery CPU or did you just get lucky with yours?

Ah wait, you have a 4790K Devil's Canyon not a 6700K

 

i guess i got lucky this time around ^^ although my previous 4790K wasnt so bad either. my sig aint current anymore, gotta update that soon(ish)... so yeah, im on a 6700k ^^

You CANNOT USE UNDERVOLT!!! You must post hard voltages! If the 6700K is like the 4790K, the starting default voltage varied between chips. Hard voltage is the only way to compare accurately!!!

There are two parts to this.

1. To see stock figures? Boring.

2. To show the max of what the CPU can handle. Exciting.

I would assume more people would want to see what is possible and to have something to work toward matching or exceeding, rather than stock figures as we all know the chips come heavily over volted.

My 6700K for my desktop build does CB @[email protected] core, cache 4.0. Takes [email protected] for P95. Just hit NY this afternoon, so I'll have it this week...

You misunderstand me. Showing an undervolt without the reference voltage means dick! What I mean by hard voltage is the voltage that is read with your set undervolt! Without that, saying your offset means nothing! Now, the difference between static and undervolting is that with undervolt, adaptive voltage is still active, so the CPU can call for more voltage under load if needed to prevent crashing. The problem is that extra voltage can jump heat significantly. This is why many experienced individuals here set static voltages, so they set it right to start and no unexpected surprises. But regardless of your choice, static or adaptive with offset, the voltage as read for your core is what is important, not your offset!!!

Yes, you have a very nice chips. My chips need more @4.8 with 1.342V core, cache 4.6
It runs fine down to 1.323V in CB and Wprime 1024M but I prefer a little headrom. laptops do not have exactly the same cooling as desktops. This is damn shame, LOL

 

That was before it was delidded. So long as there is no issue with customs, I'll have that soon. Waiting for my ram to go back on sell for 10% off (unfortunately we are in holiday season making it harder to find exactly when it is on sale). Once I get those and the motherboard, I'll be doing air testing just to make sure no DOAs, then start getting the water cooling components. But I'll do some comparison runs per multiplier to have some fun...

Yeah. Sounds a lot more fun than toy with BGA machines and low binned BGA chips. + All the talk about undervolt and stock clock speed is not particularly fun. Do the opposite. You can't have max overclock with max undervolt, HaHa

 

Come on! I'm thinking of getting two 480 rads which won't have a gpu in the loop until next year, with a monoblock and some ram blocks. It won't even be fair on cpu benchmarks (wouldn't be fair if I decided to use just one 480, but still figuring out the budget and what may go on sale for Christmas)...

Set aside money for own pleasures right before Christmas is hard Almost impossible
We'll see what Kaby lake will bring in the New Year. It would have been sad if 7700K was just like 4940Mx vs. the better overclocker 4930Mx. Higher stock turbo, don't mean a much better overclocker. It depends on... if Intel has used up a bit of the overclocking headroom with its increase in turbo boost for kaby lake. If so, damn Intel

 

I hear ya. Plus, Kaby and the 1080 Ti drop about the same time. So does Zen (CES will be busy this year)!!! After kaby is binned and prices on good chips come down, I'll grab one either way for the points...

For sure, that's why I only use static for anything above 4.6 starting at 4.7 as 4.6 works like a charm without breaking a sweat.

In terms of stability, whether a given frequency is stable on adaptive or static, either way if it's stable....it's stable!

NOT ALL SILICON ARE CREATED EQUAL! THEY ALL HAVE THEIR OWN UNIQUE PERSONALITY.

From the early reports so far, Kaby Lake seems to hint at being more over clock friendly, but again...it depends on how much head room there is (true true)... Lets just hope Kaby Lake are not a bunch of good binned and relabeled Skylakes with some extra bells and whistles LOL...wouldn't that be something...

That's the tough part we all face in buying stuff around this time of the year....especially with Thanksgiving sales (State side) and like you've said, Holidays in general...

 

just sucks if setting static voltage in bios or xtu doesnt do crap... based on previous experience, difference between adaptive and static is one additional multi before reaching thermal / voltage limit!
