Clevo Overclocker's Lounge

@Papusan - thanks!

Sorry for the cross post, but I thought this might be more relevant here.

I've been playing around with OC'ing a bit. Starting with stock multpliers and performance power settings (turbo boost enabled) my fwprime v1.55 score is

213.21 sec (8 threads / 1024M) @ 64C

Changing all the multipliers to 40 (for all core configurations) in the BIOS and the ring cache to 38 I get this score and making some changes in throttlestop (setting overclock in turbo ratio limits).

181.117 sec (8 threads / 1024M) @ 75C

I've noticed that there is some throttling going on - the clock rates gradually drop to around 3.6GHz perhaps to keep the temps at 75C. I don't know what is doing this. Any insight or help would be great!

Either way that is a 15% relative performance increase at a cost of 10C.

I tried a little undervolting but at the higher 40 multiplier my system was unstable at -100mv or so. I can't get too much out of that for OCing?

Befor doing all this I uninstalled CCC and did an nvram reset so this is all with BIOS and throttlestop settings which I'm trying to understand. As a result I've lost fan control which I'll need to reinstall CCC for.

Is XTU as bad as they say? I guess experience is a hard school and fools will learn from no other =P But it the controls would be convenient if they don't muck with the fan...

 

You have to look at throttle reasons (in the program of your choice) to be sure what limit you are hitting.

 

Is it worth to delid 6700k CPU? -6 thermal difference right?

 

It will vary from sample to sample in terms of what gains you get.

 

TS didn't report anything useful, but I think it is a TDP issue. I think there is a BIOS setting for this that I didn't touch, but my understanding is that without changing TDP I will be throttled when the CPU tries to use more juice. With fan running on full my temps are now 63C (I reinstalled CCC to try this), so I don't have thermal issues but I am pulling more power to OC.

 

Sounds like it, the stock TDP is fairly easy to hit in to.

 

Is it a bad idea to increase TDP over 45W for the 6820HK? That seems like the only hope for OCing unless I can find a way to undervolt the CPU a bit more.

 

The CPU can handle probably anything you can throw at it within reasonable voltages as long as you can keep it cool.

 

Hmm... I changed it from 45 to 50 in the BIOS but TS still reports 45 (and doesn't let me change it). Not sure what's going on. Maybe 45 is the max allowed?

 

Gotta change it under CPU settings as well.

 

Is that in TS?

In the BIOS.
Sorry I didn't realize you were using TS.

 

I'm changing both =)
The BIOS only has a user setting for TDP so I upped that from 45 to 50, but I don't see that reflected in TS anywhere - it still reports the value as 45 for TDP.

 

@Mr. Fox

I just logged into @DRevan 's laptop and help him setup ThrottleStop, just like I did before with Shakeeb Anjum . Power limits were maxed out as you recommend, under a CPU stress test, the clocks would hold perfect. The moment the GPU is involved, the CPU would throttle down to 4.0 GHz

So what use is Throttle Stop? I really see no point in it other than it helps to easily apply overclocking values. That happens on my system as well when the GPU is involved so we know it's not a power limit as I have 2 power bricks

heck the CPU throttles to 4.1 GHz the moment I launch Fire Strike and sticks @ 4.1 GHz let alone if I run it, this is without TS now

 

If its the DM2/DM3 then you might want to grab the non messed up EC.
@Mr. Fox or @Johnksss@iBUYPOWER know the exact version.

 

Same problem I'm having... I hooked up a watt meter to the wall and mine is many times at only at 280W while throttling with CPU/GPU loaded. And the CPU package is only hitting about 30W, so no where near 95W.

 

It even happens with that EC update for me. Clocks get slammed down to 4.1 as soon as the GPU gets used.

 

The problem was the BCLK overclocking, I disabled it but again, when GPU load is involved, the laptop throttles. see:



We desperately need an updated EC that solves this crap. This is one throttling machine. Oh and it was no different on the P870DM, it would also throttle to 4.0 GHz whenever the GPU was involved even with TS

 

Dang. Only option now would be @Prema I guess.

 

P775DM3-G user here and guess what, same issue! At least simmilar, with the P775DM3-G it only throttles when the GPU is also used, however working correctly when only CPU is stressed.
Result with the latest EC (1.05.03):



I am still desperately trying to find the factory EC (1.05.02) and downgrade, because if I remember correctly (after seeing the results of Phoenix) , when I overclocked to 4.2 Ghz with EC 1.05.02, it "only" throttled down to 4.1 Ghz. Both EC is cr*p, but 1.05.02 is the better one.
Clevo really needs to get their act together ... never have I seen such huge issues in the EC not getting fixed asap at MSI or Asus... with issues like these with Clevo we might just get a BGA powerhouse

 

Can I see a screen shot of your EC version?

 

I think I have never seen throttling in Fire Strike <Physics> from stock firmware If you OC'd cpu with the older DM1. @Mr. Fox

Delete INI file in TS before fiddling with new settings in Bios. Max all power limits you can find in Bios. Fire up TS afterwards and max all limits, set multi and voltage.

Edit. If I remember correctly.., I had to disable Package Turbo powerlock in Xtu before I could do proper OC in TS for my older Aw17 with 4930mx. I don't know if the same is possible with this model.

 

When you say max, you mean the max number that I can enter into the field? Like should I try and set TDP to 999 but maybe the max value is 65 or something?

I'm assuming I should be a bit more careful with the multiplier. I could try to put in 43 ...

I'll tool around - worse case I guess I will do an nvram reset.

 

Increased power limits isn't dangerous. Only to high voltage and temp. Too low voltage can hamper your OC. Start low and see what happens. Then increase multi and test again. Find correct clock speed and voltage. Then play upwards with multi and voltage.

 

Ha, first try I put in all 9's and something broke, but I think I also set the multiplier too high and need more voltage than stock if I want to go to 4.3GHz...

Anyway, success! I set TDP number to 65 for both fields and set multipliers to 40. TS seems to still remember my settings so I need to hunt them down - I quit TS for now. Somewhere beyond the *.ini file things are set I think (I hope not the registry...).

Without TS running my clock rate stuck to 4.0GHz and my score was better:

161.666 sec (8 threads / 1024M) @ 75C

So that's a 24% relative improvement over stock wprime 1.55 numbers.

I might try to see if I can get to 4.2GHz without increasing voltages because that last part worries me...

EDIT: I have to admit this is hard to replicate. I tried increasing the multiplier from 40 to 41 and saw instant throttling running wprime. Then I set the mults back to 40 and I'm still seeing throttling. The TDP seems to be 65W and the temps are very reasonable (65W currently) so I'm not sure what's causing the throttling this time around.

 

Voltage is the key if you want to increase the clock speed. Don't save on voltage if you want to go for highest possible Oc. Only temp is within reasonable values. Happy clocking

Edit Post Bios advanced settings + what you have in TS

 

It depends on temperatures regarding how far you push voltage and power. For 6820HK machines your best 24/7 is going to be a balance of undervolt plus overclock to find the efficient sweet spot of the chip.

 

Depends on how lucky you are with your BGA chips Some are really bad. Under Volt and max OC is not always the best medicine. Everything has a limit Temperature and voltage are the key for max OC.

 

Well, I thank you guys for the help. I may give OCing a rest and go back to more practical settings. Default speeds with undervolting would solve other problems if I can get it to be stable. So I think I'll nvram reset to defaults and try again another day.

EDIT: not too bad - with stock multipliers I can undervolt by -120mV cache/cpu. I ran wprime again and got a decent score: 179.383 sec The CPU clock stuck to 3.6GHz the whole time and max temp was 66C. Some of the other TS settings might also have helped.

 

I've got a problem.

Trying to do 4.2 on all cores.

Temps go all the way to 98C

Doing 4.0 on all cores - temps go under 85C

What am I doing wrong ?

Setting power limits to anything will seriously impair performance 3.0 GHz whole under load regardless of power limits or window time ,,,,

And setting voltage to 1.35 static resulted in voltage way big , over 1.5V measures by hwjnfo .

I mean... The stock bios is just this bad ?

Why is there such a big difference between 4.0 and 4.2 GHz ? The difference in performance is from 860 to 900 in cinebench .

 

Try 1.175 static, 1.35V is too high for stock operation.

 

4.0 GHz + 5% = 4.2 GHz
Your old Cinebench R15 score 860cb + 5% ↑↑↑ = 903cb Just the way it should be

@Georgel
Download TS. Rather use TS for voltage settings. Start with Bios settings as @dspboys says, then fine tune with TS.

 

By the way, I was using BIOS settings all along, not CCC.

What I'm curious is why does it go so high and if it's normal for the temps to increase from 85 to 98C for those 5% increase in performance...

As for Voltage, I will look into it, I thoguht of trying 1.35 static because this was what most sites recommended as a safe voltage at 4.4GHz for 6700K...

 

There is a difference between safe voltage and what you need for your chips. Stock voltage is often enough for 4.5 or 4.6 GHz And not all chips are likewise.

Edit. A nice guide for you http://www.tweaktown.com/guides/748...-intel-skylake-overclocking-guide/index5.html

 

Sure

gonna post some mediocre points here

firestrike @ GPU stock and CPU @ 4.2Ghz OC Fan Profile



firestrike @ +160core (custom curve)/+200mem and CPU @ 4.2Ghz OC Fan Profile



this 1070 seems to OC quite well, now think about an unlocked VBios , i even thought about upgrade to a 1080 but i dunno if it really is necessary cause i think to even get the 1080p 120hz 5ms panel if it gets released, and i only play Overwatch anyways

Edit: Here my desktop for comparison, 3770k @ 4.5Ghz and 980TI @ 1456/3900

 

Thank you!

I've looked through it, but don't seem to find what exactly is recommended at 4.4 GHz...

I don't know what is stock, stock is adaptive and on adaptive, I reach 1.45V on 4.4GHz at max... What is weird is that at max, I reach 1,45 on both 4.4GHz or 4.2GHz max, but it does get with 10C hotter on 4.4GHz...

 

added my desktop results to my previous benches , great god the 6700k absolutely destroys my 3770k never thought about that big of a gap

 

well it was to be expected with three generations between the two still, a 20% boost (clock for clock: +12.1% higher physics score and add another 8% for 4.5 vs. 4.2 ghz on the 6700K), is nothing to write home about inside of 3.25 years, thats a measly 6.2% per year on average....

 

If Zen impacts well we can expect that to increase.

 

recommended voltage for 4.4 GHz is -80mV / Adaptive voltage

If you set it in the BIOS, you cannot set a negative offset, it will only be POSITIVE, which means it's actually running higher voltage = that's why you're getting insane temps at such a small overclock, you also must set the negative offset to the cache voltage which you can't do in the STOCK BIOS, thus, Prema BIOS or TS is MUST

 

Coffee Lake anyone?

 

Well, I was able to revert back to BIOS 1.05.01 and EC 1.05.02 and the same thing still happens. Is it possible that the 2nd EC is the culprit ?

 

Don't waste your time, they are all the same on P7xxDM3. After all that throttle is an intended feature by Clevo...a feature I intend to break.

 

So Clevo allows you to put an overclockable CPU in their laptop but will only allow overclocking for CPU stress testing programs?

BRILLIANT!

ps: Been bombing you with mails for days now Prema, but finally a confirmation that I wasted my time fixing something that is not even broken (at least in Clevo's eyes)

 

Alongside an NVIDIA GPU that is getting slower when overclocked. Isn't that a dream-team.
At least with Clevo you are getting better stock performance than from the other players.

Sorry, I am working hard on getting the BIOS Mods ready and out to Partner...

 

Both for P870DM3 and P775DM3 ? I dont know what you are cooking up but it is taking much more time to make than your P870DM1/P775DM1 bios mods, so it must be packed with tons of awesomeness

 

These laptops simply cannot be used the way they are supposed to without the Prema BIOS! Period.

 

Speaking of mails...one would thing that it's impossible to fill 17GB with just emails, but apparently not:

Wondering what google does when someone runs out of space...
