Those with 6820HK, anyone stable at OC lvl 3?

Mine keep running into error when booting into Windows and needs to restart constantly. Happens to 2 computers.

 

Annoyingly no. Just level 1 and 2

 

Learn how to do your own OC using XTU.. You will reach those speeds much easily... BIOS OC is fail in AW's.. Too much voltage!

 

XTU won't let me go over the stock 36x multiplier on the 6820HK at stock and 40x multiplier at OC lvl 2. Isn't this CPU unlocked?

 

AW15 or 17? I was playing around with XTU and while I could OC to say 41-40-39, it would really go up to 3.6 GHz under full load. I do recall being able to get it to 3.8GHz before, so my current guess is that the multiplier is effectively locked at 36 unless fan perf mode is enabled.

 

Right. I have had all four cores at 4.0 and 4.1 with XTU and running Cinenbench. Here is how I did this.

1. Set my laptop to balanced mode and in my balanced mode I don't allow my CPU to go above 40%. Then I set my bios to level 3 and with it being in balanced mode on boot up it wouldn't crash as its only running 40%.
2. Then open XTU and change the multiplier to 40 or 41. Still in balanced mode, running 40% CPU.
3. Change the voltage to 1.191v
4. Then change to high performance mode with CPU running at 100%

This got my CPU to run 40x and 41x multiplier on all 4 cores without any blue screen, even running Cinenbench. It does run hot though.
I also noticed that the voltage did go above the 1.191v on high demand and didn't like this also as I don't know what the safe limit for voltage is for this CPU..... But it also goes above that when just set the bios level 2 on times so no idea really. If I knew an absolute safe voltage then I may keep it running at that but as I don't know, I tend to stick to level 2 in bios as I don't know if I will burn the CPU out soon?

I also found that if you go to bios and change to level 3, then custom and change the voltage there from 100 to 1191, that essentially is like setting the voltage to 1.191v in XTU.

From what I have seen in my experience with this is that you get the blue screen because the voltage isn't enough.

Let me know how you get on as i'm interested.

 

I do not seem to have any problems running oc lvl 3 on my 15 R2 6820HK. I can boot into windows without error and when I benchmark the CPU during a stress test the four cores go up to 4.1. I have only done this once and have since turned the oc off so I'm not sure if i would run into trouble leaving oc lvl 3 on during a longer period.

 

Anything past level 1 is not guaranteed and depends how you did in the silicon lottery.

 

OC level 3 wont take all four cores to 4.1. Only one core would go at 4.1 on level 3. All four cores would be 3.9

 

I have very little knowledge on actual OC settings but I am stable at oc3 BUT only using the 330w brick. AW15R2

 

Interesting.... I may purchase the 330w brick now

 

Sounds like nonsense to me. 240W is plenty, i haven't seen the CPU draw over 50W overclocked.

 

Ok. Maybe I wont

 

Keep in mind that CPU has more room for overclock if you use the amp. That's what I've read so far. Makes sense since you don't have the 980m heating up the place near the cpu.

 

Too clarify, I was talking about the situation where I overclocked and benchmarked the CPU only - which is pretty much the ideal scenario from the point of view of reaching top CPU performance. Clearly if someone is using the amp, they don't even need 180W, much less 330W, since the 100W+ GPU is off and the AMP has its own PSU...

 

wouldnt mind trying the 330w brick out, my 240w gets very hot on the AW15...

dont think its required for cpu OCing alone, if running a heavy clocked cpu while running the 980m full pelt, thats when i think a 330w might help..??

 

And why do you think that? The CPU TDP is 45W, GPU is 100W. 180W is sometimes not enough with heavy overclocking, hence Dell started supplying 240W. 330W might be needed for high end Clevos with desktop CPUs and GTX 980 or 980M SLI...

 

as i said..... because my 240w gets pretty hot, if anything itll at least relive a bit of the strain on the power brick..

im not limited to a 45w TDP .. the GTX980m with the premo voltmod to sails past its 100w threshold too im sure.... so there is a chance the 240w is on the edge of capability.. maybe.??

 

sure, you can overclock a 45w cpu to say 60w and the 100W gpu to 130w. 190W overall. if 240W brick gets hot, 330W may get even hotter (more power!), right? I wouldn't overclock that much anyway unless you are happy to start looking for a new laptop soon.

 

lol...... i hold 4.2 all day long with NO throttle, temps are high... but with a repaste itll go even higher.



say my power brick is hypothetically pulling 220w... thats pretty close to the bricks max, hence the heat, if i use a 330w brick and it only pulls 220w .... less heat... yes..??

 

Nice overclock, I read package TDP 56W.
What's your cinebench 15 cpu score?
All I'm asking is how long will the CPU survive this. Yes, if the 330W brick is much larger, the heat will have a larger area to dissipate over.

 

in my years of overclocking through the C2D's on to the C2Q's ive never burnt out a cpu yet.... plenty of RAM DIMMS, motherboards.... even hdds, but never a cpu.... theyre hardy little beasts.

i intend to melt the s..t out of this chip as this is what intel said its designed for.... i want 4.5ghz not sure if ill see it without putting the laptop out in the snow though...

havnt got cinebench yet... ill download it in a bit and we'll have a look

 

That would be cool. The reason I ask is on a few occasions, I seemed to have increased the clocks, but achieved no actual improvement in benchmark results. I guess that's because I had performance fans off and was in balanced mode.
BTW any idea how to toggle fan mode without rebooting? Clevos have a hotkey for that.

 

not too sure what you mean..... im using HWinfo to control fan speeds..?

 

My Aw15 R2 has this "performance fans" mode which basically cranks out more RPMs that I was able to a chieve through HWINFO. The downside is that it's too loud to use the laptop without noise cancelling headphones, so it would be nice to be able to switch this on and off without restarting.

 

ah.......... i know my BIOS has 2 fan settings 'standard & performance'... but on performance it simply sets them to 100% and thats it, crap!!!

no pwm control at all.... AW need to get a proper dedicated bit of SW for this task..

 

Yeah, the thing is that it's not just 100% in terms of what HWINFO considers max speed. LIsten carefully, fans are much louder under load than max HWINFO fans, and I could actually see better benchmark results in performance mode.

 

lol.... well your right!!!

thats damn loud through BIOS , yet HWinfo at 100% is nowhere near as loud, HWinfo states my fans top speeds as 5400rpm... yet they obviously run faster than that..?? HWinfo needs an update me thinks.

 

Double post

 

Agreed... anyway, my best cinebench r15 cpu result was 770. do post your score.

 

here it is.....881

 

@skunk1 Did you run that at 4GHz?

 

Wow, what are your bios settings? I can overclock to 4.2GHz using your settings, but the benchmark results are actually worse than when using plain OC2 BIOS settings + performance fans.
Intel XTU is showing constant power limit throttling. Any ideas?

 

that run was 4.1ghz (on all 4).... can do a 4.2ghz run, but ill have to readjust the voltages to get it stable again, my AW15 will run 4.1ghz on stock volts....

never used the BIOS to OC since ive owned it....... only use XTU

i used to have serious throttling issues before i had control over the fans..... now i see no throttle!! just got lucky with my silicone i think

 

It's a bit low for 4.1GHz.

This is for an i7-4700MQ, Skylake gain is typically 10% so you should get a similar score at 4GHz.


Try setting Cinebench priority to high using the task manager and see if that helps.

 

hmm....???? not too sure maybe i need more voltage..?? ill try priority settings but maybe that chip is just better.... he is at 4.4ghz though

 

Looks like some sort of clash between the BIOS and the XTU. I unstalled XTU and consistently getting 775 Cinebench, with XTU - no matter what settings - I'm lucky to get 700. Anyway, the OC2 performance is plenty I guess might flash prema bios at some point (once the warranty runs out)

 

@skunk1 A 4GHz Skylake CPU is equivalent to a 4.4GHz Haswell CPU. Perhaps XTU is also responsible for a lower than expected score or maybe it's RAM.

For overclocking you can get some idea from HWBOT although mobile results can be a little lacking. 6820HK for example. Note how the 1374 XTU score is using adaptive mode rather than just offset.

 

My 17R3 would post, but never made it into Win10 with LVL3 OC set in the BIOS. I guess I lost the silicon lottery.

 

Stop using the BIOS OC!! Too much voltage!! Use XTU... You have to manually tweak it and you should reach 4.2-4.3GHz

Or use Throttlestop. Normally a better choice.

 

I'm using bios OC and it seems stable. I did the manual customization and set extra voltage of 50 and set everything else at multiplier at 40. If you use the default settings it pumps a ton of voltage you probably don't need.

 

BIOS won't even POST when oc'd to 4.2. And sometimes unstable at 4.1. I'm not sure how on earth XTU would help if I can't even boot Windows. Throttlestop won't OC past what's set in the BIOS (at leas the current version running on a Skylake cpu). So if you boot to 4.0 or 4.1, ThrottleStop won't let you get OC beyond that.

 

That's true. XTU can't get past BIOS limitation. Any workaround for this?

 

That is only partly true. You can influence the core voltage and even some other voltages depending from which OC Level you switch to the custom overclocking option.

If you set the OC Level 3 HWMonitor will report an IA offset of +0.1V and a LLC/Ring offset of +0.1V. These voltages will stay the same when you now switch to custom overclocking in BIOS and they are not affected by the Extra Turbo Core Voltage setting. The same effect will appear when you first choose the OC Level 2 in BIOS and then switch to custom overclocking, but then IA offset and LLC/Ring offset will be at +0.05V.

My recommendation is to set OC Level 1 and then apply your custom settings. Because then there will not be extra voltage applied to IA and LLC/Ring offset.
I even cannot recommend to switch from disabled overclocking to custom overclocking in BIOS. IA and LLC/Ring offset will then also stay at +0V according to HWMonitor but when you take a look at the VCore while using Prime95 or a similar software you can see that there will be a VDroop applied.

What I have done now is to switch from OC Level 1 to custom mode and raise the multipliers to the same level as in OC Level 3. So I have the maximum guaranteed overclocking by Alienware / Dell with no additional voltage applied. This runs perfectly stable and much cooler than the original OC Level 3 for me.

 

Great pointer @MorLipf. Thank you.

Just to confirm, in BIOS, change it to OC Level 1 then Customize that to OC Level 3 settings found in BIOS?

 

Yes, correct.

 

4.1GHz Stable.


Temps holding well....Noticed LLC/Ring Values at 0.051V.


These are the default OC Level 1 Settings. Notice CETV is at 0.


These are the default OC Level 3 Settings. Notice CETV is at 100.



OC Report:

In BIOS, I've selected "Custom" and have entered these values, which are OC Level 3 values:

1-Core Ratio Limit Override: 41
1-Core Ratio Limit Override: 40
1-Core Ratio Limit Override: 40
1-Core Ratio Limit Override: 39

Core Extra Turbo Voltage: Left this at 0

Power Limit 1: 92000
Power Limit 2: 92000


I've left the Core Extra Turbo Voltage to "0," and it seems to be holding steady. The value of CETV on OC Level 3 is set at 100, which seems to be way too much voltage....

So far so good....holding steady....I'll report back if anything changes.

Thanks for your input @MorLipf

 

nice!!!

push your BCLK up by 1mhz ..... and youll run the true 4.1 constantly.....

 

Just finished gaming for a few hours on 4K and everything is still smooth sailing....first two spikes were Tomb Raider benchmarks @ 4K...then rest is gaming at 4K.



Do you use MSI Afterburner? What's the best tool to tweak out of the ones available?
