Clevo Overclocker's Lounge

Potential CPU (6700K) or motherboard degradation after constantly running at high voltage:
The last 3 months, I was running my 6700K(4.7GHz) with BIOS input voltage at 1.282V and c-states-off for 7x24 (daily max temp < 90C). Throttle Stop showed voltage around 1.44~1.45V at idle. I didn't care the voltage that much, because 1.45V is the max voltage that Intel recommended and I believed modern CPU barely fails.

Until few days ago when I was browsing video in my hard drive, my screen suddenly froze. I thought it's nvidia driver problem, then I switched back to the previous driver, the problem still existed.
I decided to run the RealBench again with the 1.282V that I used to pass for 5 hours, it froze within 10 mins, even though the core temp was only around 90C.
I thought it's the thermal pad problem since I am using a thick copper shim, then I changed the thermal pad into thicker one and made sure it has good contact with the heat sink, and raised the voltage to 1.285V to run RealBench again, still froze after 20 mins with package temp around 93C.

Then I started to doubt that my CPU/motherboard might degraded overtime, I went back to my last safe and stable settings(4.6GHz @1.235V BIOS) and ran RealBench, screen froze(cores<=85C) again after few hours when I was sleeping. Finally I raised the voltage to 1.24V in BIOS, it passed the 4.6GHz that I could pass with 1.235V in the past.

Now I went back to 4.6GHz for my daily drive, and guessing either my CPU or mosfets/capacitors on the motherboard has degraded.

 

I have seen it now.

Only played the video from within NBR, didn't open it in youtube before.

@Mr. Fox Is the setup plug and play, or it requires any cable play to work?

 

Found some things after a quick search.

Would this work?

This is a bit expensive in Romania, but seems like a safe bet. Is it any good?

http://www.pcgarage.ro/ventilatoare-radiatoare/noctua/nf-f12-industrialppc-3000-pwm/

This is one of the stores with a larger stock, any advice on what fans are actually okay? I really cannot order from outside of Romania

http://www.pcgarage.ro/ventilatoare-radiatoare/

There are many, but I have zero expeirence with fans.

Also, I feel like asking this: Adding a fan under the fans of clevo. Can this be any dangerous? Like, can it force the fans of the Clevo to spin even faster than they would normally and short circuit them? (Via eletrcomagnetic override?)

 

I refuse to believe it is the processor itself. MB components is more likely the cause.

No. Put all fans like in my MOD
This fan is good. Buy 3 of them without thinking.

 

Cool!

Thanks!

How about the fan controller module? Should it do justice to the whole ensemble?

 

Every time I go and copy something these guys do. Once I finish it, they have something better. I can't keep up. I gunna get one of those change phase, or phase change, whatever they're called coolers and hang it off my laptop. @Mr. Fox @Papusan @Johnksss@iBUYPOWER @bloodhawk @D2 Ultima @Prema

 

And end up with a non functioning laptop in all of 7 minutes.....

 

LOL.

 

I think you're being generous with the time. I just Googled those coolers. I would probably last about 3 minutes before I destroyed the laptop. Dam those are expensive. 10,000 BTU AC is on the list. And you're right Validating and Benching are totally different. My 5.2 ghz didn't bench for more than 30 seconds before it shut down.

 

Can you bench 5.1 ghz?

 

Stupid thing about my current 7700k. I havent been able to bench at anything over 5Ghz. Can Validate though at 5.2Ghz.

Going to try it in a desktop to find its actual ceiling.

 

CPU is more lenient than the GPU is in terms of temps and clocks. So it's going to be power and voltage.

 

Hoping thats the case. Gonna make some changes and test things out once im back.

 

Not sure. If it's the processor, I could still change it. If the motherboard components are aging, it will be sad... T.T

Since I can't do 4.7GHz anymore, did some deep optimization and made the best out of the 4.6GHz (closed to a 4.7GHz score I guess):

 

Well....Running 1.4v+ volts is not really helping your situation much....

 

The simplest is often the cheapest as me. Get a cheap used 12-15V psu or the like. I don't know what it's called the fan conector... Obtain cable with a connection for the 3 fans needed, then welding 3 pieces of them to the psu cord itself. Or @Q937 can show you what he used. Maybe see if yooo can obtain fan controller +++ as @Mr. Fox But I see yooo haven't many choices home to obtain what yooo need.

The score is good. Too rule out the processor... See if you can try it in a desktop. Yoo are damn unlucky. Hope all will be good bruh.

 

Right after a bios reset.... Fans on auto. Nothing extra. Check the voltage....




Altered settings.

 

So what did you change re the vcore to get that much lower? Static? What vcore did you set (how much does it droop?)

For 4.6 I leave it on adaptive +25mV and it maxes at 1.4V-1.45V at idle (when it's not speedstepping down to <2ghz/0.8V) and settles right on 1.30V on heavy multicore stress test

 

You guys love that adaptive stuff, that's why. And your adaptive voltage is based off a high factory bios set voltage.

So try static and you will find things work a bit differently

 

I've done a 5.1 on Geek Bench. I don't know if that counts. I'm going to try Cinebench now and see.

 

This was in the description of my video on YouTube. Maybe you did not see it.

Just a no-frills look at the EK Vardar Furious 120MM fan upgrade on my modded CoolerMaster U3 cooler.

You don't have to buy the expensive Vardar fans, but now that I have them I do recommend them. The name "Furious" is appropriate. They pump lots of air and the high static pressure helps a great deal. If you do not cut big holes for the fans and expect them to push air through the grille the high static pressure would be even more important. Before I cut the holes to remove the area covering the fans the Rosewill fans didn't push enough air through the grille to make a huge difference.

 

OK that's a big NO on CineBench trying 5.1 ghz I didn't make it far. How many hours do guys like @Mr. Fox @Johnksss@iBUYPOWER @Papusan @bloodhawk have into overclocking? How long have you guys been doing this?

 

Maybe you should start a little lower? More like 4.9GHz and see how it goes. Then up.
wPRIME v1.5 A good tool to benchmark and stress test your CPU. Run as adm. Then select 8 threads in advanced settings and fire up 1024. Use HWiNFO for monitoring your hardware.

 

Brother @Johnksss@iBUYPOWER started before I did. I think I got my glorious addiction started in like 2008, something like that. Most of what I know I learned from John. He is my sensei. Even so, every CPU is different. You get an idea of a place to start, but copying someone else's settings exactly seldom works for everyone. It can if the overclock is conservative, but once you start searching for the edge of functionality there can be a lot of variance from one CPU to the next. I have many hours of trial and error into every CPU I have overclocked. I'm still not able to bench at 5.2GHz with either of my 7700K CPUs, but I haven't given up yet. I'm running out of ideas, but I'm still going to keep trying. If I can't identify what I am doing wrong I will ask for his help. If he can't help then it will be time to declare 5.1GHz the max for this sample. The 7700K in the Tornado F5 doesn't overclock as well as the one in the DM3. It can just barely do 5.1GHz and only behaves well at 5.0GHz. And, the settings on one are all different that the other one. Settings that work perfectly on the DM3 won't even load Windows without a BSOD on the Tornado F5. The motherboard and components supporting the CPU can also come into play even if all of the hardware is identical. Some components can be stronger than others with two identical motherboards. So, part of my testing may include swapping CPUs between them. It is entirely possible the 7700K in the Tornado F5 is better than the one in the DM3 and it could be another component that makes it not overclock as high as the one in the DM3. The only way to tell is toe swap them and see what changes.

 

Been at it for years, but not at the level of @Johnksss@iBUYPOWER . the most i have done is LN2 a few times.

 

I started overclocking in the pentium II days, 400mhz to 533mhz

Laptops I started with back in 2005 getting a pentium M from 2ghz to 2.4ghz and the X600 from 400mhz core to 600mhz core

 

He have problem to obtain parts. But the Noctua fans he can obtain is proper and the controller will work. He need only buy a cheap whatever 12v adapter and solder the cords.

 

That's it, just need to keep putting time in. get some experience. I have a good 5.0 ghz OC but that's the one I copied from you. I actually forgot and left that on all day. Running my architectural software, estimating software. It worked fine. I'll just start lower and keep plugging away. I do appreciate all the help from you guys.

 

That's a long time, dealing with these things.

 

Awesome. Glad those settings for 5.0GHz worked well. They might not work at all for someone else. You have a decent CPU sample if those settings work right.

 

I still remember sticking my Radeon 8500 in a freezer to remove the stock heatsink and thermally glue a crystal orb to it

 

If interested. From Notebookcheck Germany. I translated it in pict.

 

Ya they did, and the architectural software I use, I was doing a lot of Ray tracing that day. It uses the cpu at 100% but it plugged away no issues. I normally never would of tried it, just completely forgot to reset the profile in the morning to Daily use.

 

It's all guesswork

 

WTH! I'm trying to fly before I can walk. Will need a little more time tweaking.

 

I'll see you guys tomorrow. Have a good night.
Take Care
Jon

 

It's a lot easier than it was back then though I was vbios flashing at that point, I had a pre-release BIOS with tighter memory timings that would do 315/315mhz, awesome in 3dmark 2001 se

 

Still interesting with rumors We have not come further than the end of March

 

Well it all depends how well people are keeping an ear to the ground and properly filtering it all to build a picture.

 

The moment after loosing your stable settings, playing with BIOS settings and flashing firmware betas back and forth...just to finally, after a long days work, meet that good old but somewhat new sweet-spot once again:

http://www.3dmark.com/spy/1428243

 

Nice.
My 1080's dont seem to want to go anything over 2025
Anything over that and crash to desktop. Cant wait for your modded firmware, specially if it will let us play with the voltage.

 

No worries that's stock throttle vBIOS, there is still a lot of untouched potential in our babies...
I am sure John or Fox will show us some 13K TimeSpy here very soon, once they get the time to play with the new DX12 drivers...

 

Yeah, i have been trying to set custom VF curves, but every time i do that, the frequencies just stay stock. At first i thought i was doing something wrong, then i ran it with a similar curve to the one i was using with my Strix 1080's a while back , and even with that the frequencies were bone stock.
Giving it an offset however work, but anything over +175 to +195 (anything that would push these over 2025 sustained) , causes crashes to the desktop. And this is while being on top of an AC, with sub 40C temps.

 

Not touching fancy v-curves here, all too complicated for me, just using good old NVIDIA Inspector.
378.92 seems like a good driver for DX12.

 

Yeah had to go that way when, oddly, i couldn't even go over +175.
Also for some reason i haven't been able to install any driver from teh 378.XX chain, both stock and modded refuse to install, saying incompatible hardware. Any idea why?

Ill take a look at the device ID's once im back.

 

Strange, working fine here, stock NVIDIA Notebook x64 W10 378.92 driver and installing just fine P'n'P.
All I did was setting it to high performance in power settings and disable g-sync, no other changes. GPUs set via Inspector the rest directly in BIOS.

Maybe DDU in safe mode with latest version:

http://www.wagnardsoft.com/content/display-driver-uninstaller-ddu-v17061-released

 

Thats the thing, i actually DDU'd right before trying to install it. I didnt have the time to really dig into the issue so just installed 376.33 and called it a day. Ill try the latest stock.
Could have been Windows trying to install its its BS at the same time ? But since i DDU'd right before , that should not be happening. I really dont trust Windows to be honest. Will keep you posted.

 

If I use my previous stable +215 core overclock I get black screen lockups with 378.92 drivers. Went back to older drivers and the black screen lockups went away immediately.

 

Thanks! I might just stick with it now, waiting to see if there's something new and powerful coming out later this year.

Your voltage is very good. My trashish eats 1.27~1.28V to sustain 4.6G under load and draws 100W in CNBR15, while yours is only 70W... Such a difference...

 

Damn, if those black screen lock ups are not on top of an AC then good chance your 1080's have even more headroom.
For me to even get a bench done @ anything over +190 i need to use a fan with the bottom cover off or plop it on top of the AC. And even then anything sustained over 2025 instantly crashes to desktop.
Fortunately though with the new new VC heat sink and my imporved thermal pad pad job, i do not get black screens no matter what.
I can post a detailed description of the pad placement, but it needs the Fujipoly 3mm pads. I observed that the Fujipoly 0.5mm pads on my VRAM barely make any contact with the heat sink, unlike the Artic ones. Not really sure whats up with that.
