860m is a Beast

That's an awesome chip on stock voltage.
Use Inspector to overvolt. That should push the envelope further. Afterburner doesn't work for voltage.

 

Gotta agree with you, guys, this is definitely a great card for the money, and with Prema's awesome BIOS, even more so! I would have one question, though. Is there a way to ensure that the GPU clock stays turbo-boosted to the max while gaming? Does the power management mode or other settings in NVIDIA's Control Panel, for example, affect the behavior of the GPU clock under stress ? I noticed yesterday while playing Wolfenstein: The New Order that the GPU clock mhz went down from ~1300 to ~1100 mhz or so at some points. I was using Adaptive power management mode and tried changing it to Maximum performance without achieving any difference. I think I was at +300 on the core and +500 on the memory, while the temperatures remained at moderate 73c at max. Is it so that I just have go lower on the clocks in order to find stable maximum performance?

 

It is normal that the card clocks up and down according to what is required. With the Mod on Clevo's there is no more throttle unless your temps rise through the roof.

 

Just got my 860m unlocked thanks to Prema; time to start testing

 

What is the highest clock you guys got WITHOUT touching voltage?

 

almost everyone with this gpu should be able to max out the nvidia lock of +135mhz on the core without an unlocked vbios. I was able to get to +190 reliably on stock voltage.

 

Are you using Nvidia Inspector to change the voltage? Does it keep the voltage even after re-booting? Thanks

Here is my setup with Nvidia Inspector. Can you guys post yours?

 

Just curious, how come even modded laptop GPU's can't adjust fan speed and power target like desktop cards can, and why does temp target and voltage control only work in Inspector but not Afterburner or Precision?

 

So I've gotten it all nicely setup, but now when I reboot, the clocks go back to stock. Ive tried creating a shortcut for the OC clocks and putting it in the startup folder, but it still wont apply the clocks when booting. How are you guys getting your clocks AND voltage to apply each time you boot?

 

FANs are controlled by the systems EC controller not the GPU.
Temp Target can be set, but isn't needed. Power target can be enabled but isn't required either as I removed the throttle in the Mod.

 

Putting the clocks shortcut in the startup folder won't work because Windows 8 prevents programs requiring admin privileges from auto starting through this folder. The only way to accomplish this is through the Windows Task Scheduler.

In Inspector, right-click "Create Clocks Shortcut" and select "create clock startup task." This will add a task in Windows Task Scheduler to automatically apply your overclock and overvolt at startup when you log on. The clocks will still reset whenever your system wakes from sleep or hibernate, so you need to add a manual trigger to the task on System Power-Troubleshooter Event ID 1 to have it automatically apply the settings on resume from suspend mode.

Thanks for the explanation, Prema. But why is voltage adjustment grayed out in Afterburner and Precision?

 

Because those software's voltage don't work for mobile cards. Only Inspector had voltage control.

 

Mr. Fox's (modded, I'm assuming) 780M has voltage control in Precision, so I guess it varies from card to card: http://forum.notebookreview.com/ali...nvidia-geforce-337-88-whql-9.html#post9693985

 

What is the max SAFE voltage for the 860m maxwell? 1.180V ? Also what about max safe temp?

 

Holy CRAP! I am completely amazed. I spent the better part of today overclocking and testing out the best settings.
On the core clock, I managed 1387mHz (+290mHz) and the memory clock I got 3105 (+600mHz). The voltage under load is 1.100 volts; temperature max is about 85 (toasty, but acceptable for this GPU on this chassis). So what does this mean in real world performance?
For starters I have now slightly beaten the 870m. Yup
Battlefield 4 run on ultra (with MSAA off) at 60fps. On a 21mm laptop. That cost 1500$. Holy Sh*t...

 

I'm looking at maybe buying a SAGER and I have the option to get 860m SLI (8GB total) or a 880m 8GB.

Which is better in the end? Because for what I'm seen 860m has some great results overclocked. And having 2 of those sounds better than just 1 880m.

Thanks for the help.

 

go for the 880m, single best card first, then you can add another 880m down the road. An overclocked 880m will be more than enough.

 

The MXM GTX860M (incl SLI) is a Kepler chip. The onboard GTX860M (well most of them) are the Maxwell that we are pushing here so much...

 

What sort of score do you get on 3D mark fire strike and sky diver?

 

I get a black screen with Graphics Test 1 and Combined Test with the Sky Diver benchmark. This article says it was fixed with the latest drivers, but apparently not: Futuremark Press Releases — 3DMark Sky Diver has landed

Although I notice they included bewb jiggle physics.

 

Sky Diver was broken for me also. Latest beta fixed it for me.

 

Hi, I'm pretty new to the world of Graphics cards and what not, I just received my Lenovo y50 about a week ago, I've already overclocked my 860m to to the max locked core clock and I also want to go beyond that like you guys. XD What can I do? or what should I do?

 

Wait for Prema to release a modded bios?

 

How do you like the Y50? How is the build quality? It's plastic right?

 

So I've gotten the clocks to apply when waking from sleep but in addition to applying the clocks, it opens up the Nvidia Inspector Window... Any way to prevent that?

 

Aluminum top and bottom, soft tpuch plastic palm rest. Good build quality, runs cool and silent.

 

Alright, so turns out that a task is not necessary; the OC clocks apply themselves automatically when waking from sleep. Perhaps this is because in Nvidia Inspector I've set it to apply clocks on boot... ? Either way, clocks apply when booting and when waking from sleep so I am happy

 

Here's the 860m at 1200 / 5400 with 3DMark SkyDive, including starting demo with BewbJiggleFx.

Actual bench starts at 4:00

Playing with a GS60 this week with the GTX870m. It's power hungry and I can't get more than a 35Mhz overclock without heat forcing it to down clock.

My best run with the 860m in the Razer Blade Pro was 4443 on Firestrike. The best I can get out of the 870m is 4425. Lame.

 

Man, that 4900 smacks the 4702 around a bit.

wow I'm surprised the CPU didn't throttle

 

did you experiencing throttling on default clock?

 

To be honest i don't rely too much on benchmarks anymore. Maybe they are more or less accurate most of the time in giving you an rough overview of your gpu's performance, but sometimes it doesn't reflect the real gaming performance at all.
For example, i was very surprised by the 470 (desktop) performing on par with the 860m on Tomb Raider or Far Cry 3, although the 470 only has a Firestrike score of ~2800, while the 860m (stock) has ~3900...

So, i would take synthetical benchmarks always with a grain of salt and not as a proof of being on par with xyz... Therefore only real benchmarks can give the accurate answer.

 

For comparison here is my sky diver benchmark.
Stock Core.
6ghz mem. 247 undervolt clocks.

Got a noob question, does 3dmark 11 work on Win 8.1 ? seems it doesnt

 

Nice. I'm going to push it a bit more. Maybe underclock/undervolt the CPU a bit and see where it goes. CPU is actually i7-4810MQ, but for some reason 3DMark keeps seeing it as 4900. Surprised they haven't fixed it by now.

CPU won't throttle until about 95C. 90C is quite high, usually with intense gaming it's usually below 87C.

 

isn't intel's temp limit at 100C? I'm just surprised how this chassis kept the CPU down to 90C even with that single fan and extremely poorly curved heatpipes

 

So far I'm really enjoying the Y50, I don't really know how to asses the build quality. Like what Chow Meow said, it has an aluminum exterior (lid and bottom cover) and the palm rest s made of soft touch plastic. The backlit keyboard feels really nice too touch and gives a good illumination when playing in the dark. Oh the speakers, god how I love it! Maybe this is because I haven't owned a lot of speakers yet but the quality to me seems to be pretty good, It's can get to a good amount of volume but it doesn't get as loud as external speakers go based on my friends JBL portable speaker.

On a side note before I re-applied the thermal paste I did a prime95 and furmark stress test for 30 min, and I got these max temps.
GPU: 86*C
CPU: >98*C

 

I thought it was cooler... I find a bit toasty that 98° CPU temp.

Prime95 and Furmark/Kombsutor will bring any system to its knees. Not real representative of what the system will do during gaming. It's good for checking stability, but for temps, expect them to creep up to max every time and/or throttle.

 

I remember seeing some benchmarks showing several GPU´s including 770m and 860m for there overclock potential and it showed that the 860m actually not so overclockable, especially compared to the 770m.
I don´t what to believe anymore!

 

That was probably the Kepler 860M.

 

Yup, that must be Kepler. notebookcheck.com has a great article on 860m Kepler vs Maxwell. Benchmark showed that overall Maxwell was 10% faster than Kepler.

 

Must have been with stock vBIOS...

 

What range of temps could start being dangerous for the life of the GPU?

It throttles at 93° but... Does it mean that until that temp isn't dangerous for the chip?

Sent from my Nexus 4 using Tapatalk

 

Yes.. 93C isn't going to hurt the chip. If it did they would throttle or shut it down sooner.

 

I'd say anything over 80C is dangerous for a mobile GPU. If I remember correctly every 10C rise in temperatures cuts the life of a chip in half. So if your GPU would last 4 years at 80C it would only last 2 years at 90C. Case in point 93C is very dangerous.

 

Anything over 80C? I think that's overreacting a little bit.

I had a single slot 8800 GT 512MB that survived for over 3 years running at >90C every single day with a decent overclock and overvolt. It's still alive and kicking in the old rig to this day. Most of these cards will throttle or shut down well before temperatures which would cause permanent damage, same goes for CPU's. For some reason, temp limit on my 650M is relatively low at 91C, at which point it begins to downclock core, although I know Kepler tops out at around 100C.

I'd be worried if you went over 95-100C all the time, otherwise keep on truckin'!

I've heard that rule of thumb about component lifespan being reduced by half for every 10C heat increase. I think the same thing regarding writes on SSD's applies here as well. Higher temperatures (within reason) will reduce lifespan, but you'll have upgraded to new hardware by then, so it's not really gonna affect you, unless you're trying to keep that piece of history for a decade or more! :laugh:

 

is this a good 3DMark result? (I have only experience with the 3DMark11 Version...)
for my W230SS with Prema Mod Bios and i7-4710mq (3DMark recognized it as 4712mq?! don't know why)
i put a 80mV undervolt on CPU and +175MHz OC on the 860m coreclock.
Temps: CPU 70°-75° - GPU 60°-65°
(at least with only 1x 8GB RAM 1866MHz module - no dual channel yet)

seems to be a good score, my 3DMark 11 is incredible high:
http://www.3dmark.com/3dm11/8456658

my old P170EM with 680m could do 6000 (stock) 8000 (OC) 3D Mark 11 score.

 

Wow, that's a gigantic graphics score. How come?

Here's my scores. They're among the top 8 on 3dmark11, for this combination of components, apparently

NVIDIA GeForce GTX 860M video card benchmark result - Intel Core i7-4700MQ,Notebook W230SS - P6230

And top 4 results on FireStrike, yay:

http://www.3dmark.com/3dm/3445754? - 4558

If my effective clocks are 1338 / 5710 does that mean i'm running +710 on memory?

Sky diver: http://www.3dmark.com/3dm/3446005? 14180 - that chick has some nice digital calves, yum.
