860m is a Beast

Here is an example of scaling screenshots: The Problem with High-PPI Windows Display Scaling - Tested.
Try doing the screenshots, please.
I know it will not show the blur, but it could be useful to compare UI size.

Does 720p really get a bit blurry? How about 900p, is it really good, crisp, perfect scaling? Did you try 720p/900p scaling in games?
Could we continue this conversation in w230ss owners lounge?

 

Anyone notice any performance bumps with more mature drivers? I have installed them, but haven't had time to check. I still love the 860m though.

 

Hello,

Can someone teach me how to overclock? My laptop is Lenovo Y50.

 

Yes i have the Y50 UHD GTX 860(4gb) Maxwell

 

i am playing medium on 4K battlefield 4 (Lenovo Y50 UHD)

 

Can i have the one for the MSI GE60 2PE please ?

 

Hi,

I have been following this thread pretty closely the past few months.

I have a w370SS with the 860m. I am new to overclocking. I did download NVidia Inspector, and I can get +135mhz on the core, and +230mhz on the memory. My GPU never gets above 65 celsius (I use a laptop fan).

I understand that I have to unlock my bios using the Prema Mod. I'm not sure what the next step is after that. am I then able to increase the voltage and core/memory further using Inspector? Or is there some different tool that I have to use? Is there a place for me to find 'average' voltage/core/memory combination that other people have succesfully achieved?

Thanks!

 

Can someone with a stock clocked GTX 860M, 344.75 driver and Tomb Raider do me a favor?

Can you benchmark Tomb Raider on ultra preset and 1080p for me? But one time with High Precision on and one time with High Precision off. It gives me with a GTX 850M a impressive FPS boost from 30 to 40 FPS with no impacts on visual quality, and I want to see if that applies to a GTX 860M too. Don't touch other settings, just High Precision!

Thanks.

 

Hi.

Is there any work in progress about a vBios for acer V nitro ?
Could I undervolt CPU without any bios mod?

Thanks

 

Just got my Lenovo Y70 with a 4GB 860M and this thing OCs like a beast! I've oc'ed the memory to 6.3GHz up from 5GHz stock, a healthy 1.3GHz OC! :thumbsup: 6.4GHz is also possible for benching purposes but I get artifacts.

The core is stuck on +135MHz but I'm still on old drivers. Would I really need a custom bios to bypass this block? I remember with my 750 TI, Nvidia released some new drivers which allowed higher OCs.

 

on a Y50 here, what did you use to OC?

 

MSI Afterburner 4, the latest version. I haven't touched any voltages and the GPU went to about 65C when running EVGA OC Scanner.

 

I would also like modded vBios for Acer Aspire V15 Nitro.

You can undervolt CPU without any BIOS. Download Intel Extreme Tuning Utility. I'm stable at -80mV, some people get better results.

 

Hi, i need advice about vBIOS flashing in G750JM.
When i flashing this happen
Zippyshare.com
Why PCI Subsystem is different? What i can do?

One more thing.
In BIOSv 207 i dont see options called "CSM" and "secureboot"
Can i flash safely?

Thanks for answer.


I'm stupid (y to z revert in keyboard) vBIOS work excellent.
Thanks Prema for great vBIOS.

 

That's normal. you can just flash it.

If your current vBIOS is different from the 82.07.10.00.07 you can make a dump first by typing:

nvflash --save backup.rom

 

hi prema,
can i have the msi ge60 2pe gtx 860m custom vbios please ?
+ a little guide of how to install it (newbie here)

 

I did backup vBIOS via GPU-Z

NVIDIA GeForce GTX 860M video card benchmark result - Intel Core i5-4200H,ASUSTeK COMPUTER INC. G750JM
Max OC +230 | 395 | 1.200 V
Im so unlucky

Any tricks for better OC?

 

Thanks for advice. I'll do this when I get back my laptops from Acer support...
It's was defect ... CPU limited to 750mhz, fan didn't cool enough and a dead pixel screen...

I hope I could be happy if there will be a vBios mod for acer V nitro. :thumbsup:

 

the benchmarks are all well and good.how does this gpu stack up when running things like metro 2033,and crysis 3?

 

In BF4 on ultra without AA, map "Siege of shanghai" i have 50-60 fps.
860M@1320/420 and i5-4200h with ThrottleStop.

 

I have the W370SS with the Maxwell 860m, and GPU-Z and Inspector are showing the maximum voltage of 1.068. Is this accurate? I can only get to 675 mhz on the core clock and 1353 mhz on the memory clock - does this seem about right for stock voltage?

Additionally, why does Inspector show the memory as 2705 while GPU-Z shows it as 1353? It seems like for every 20 mhz I raise it in Inspector, I get 10 mhz in GPU-Z.

Edit: Looks like I was blind, I can switch the power slider more to the right. I'll have to find a balance between voltage/temp and FPS

 

The power slider will make very little difference, it's only about 0.05V increase even with slider all the way to the right so it may do nothing for you. Also GPU speed should be between 1000-1100MHz. Load up the GPU and check the core speed then.

Also, GDDR5 is quad pumped, so 1353 = 2705 DDR = 5410 actual (double pumped DDR)

 

Appreciate the explanation - thanks! Looks like my clock speed is 1232 mhz - does that sound about right?

As far as I understand, the base clock is 540 mhz, and I overclocked it to +135 using Inspector. Not sure how that adds to 1232 even if I double it

And you are right, even with the slider all the way to the right, I could not get +135 core and +300 memory clock, without getting artifacts. For now I think I will stick with +135, +200, leave the voltage alone, and then eventually unlock the bios. Want to make sure I have a full understanding of everything before I do so.

 

Clocks will show at 540MHz on the main GPU-z screen, nVidia Inspector should show the proper clocks under (est Max).

Use nVidia Control Panel to set GPU-z to use the nVidia GPU. Then click the question mark icon (?) on the right of GPU-z and click "start render test" then go in the sensors tab of GPU-z and it will report your core clock speed under load. GPU-z is not reporting the proper speed on mine either under the main window, but it does when I use the sensors.

 

Yeah, my estimated max is 1233.

As far as I can tell, these are my current numbers, using inspector

Core clock: 1233

Memory clock: 2705

Votlage: 1068 mv

And my max temps with a laptop fan is 66 for the GPU. I'm a little surprised that I can't increase the memory clock any higher, without artifacts.

 

Did you increase the voltage using Inspector? I think that might be your problem... It's a risk too as too high voltage/mmeory clock can brick your GPU..

 

I increased it to the maximum allowed in inspector which seemed to allow for a vey minimal increase to the memory clock,which didn't even seem worth it as it increased the laptop temp as well.

 

Hi all,
where i can find mod vbios for ASUS ROG G750JM GTX860M, there is a link of my laptop: Notebooks & Ultrabooks - ASUS ROG G750JM - ASUS
Thanks!!!

 

Prema Mod GTX860M vBIOS for G750JM

 

This mod depends for maxwell chipsets or kepler or for all? Can i upgrade and not be any problems of that?

 

This mod depends for maxwell chipsets or kepler or for all? Can i upgrade and not be any problems of that?

 

Perma has made it for G750JM so yes it will work.. Just make sure you know how to to bloody flash the vBIOS and don't brick your machine doing it.. Mr Fox always says doing vBIOS flash through DOS is safest so use that method..

 

Yes i did that, and after upgrade a bios i can't see any differences...

 

Well you can OC more now... The power limit has been removed.. Read this thread and learn how to OC... lot's of examples here..

 

I am running my 860M with the aforementioned +135 core +200 memory in Inspector, and I am only getting a 4180 in Firestrike, which after reading some of the original posts in this thread, seems low. My processor is the i7 4810.

During the Firestrike test, I had inspector running which reports a steady 1232 mhz on the core, and 2705 on the memory (both at max). voltage at 1068 mv. temperature never above 66.

Am I missing something? Or is this an expected result for these specs?

Firestrike is reporting this:

Core clock 675 MHz
Memory bus clock1,353 MHz

Inspector shows the 'est max' as 1233 mhz. Still not quite sure I understand the relationship between the 675 (which is presumably 540 + 135 OC), and the 1233.

 

You have to use the Mod BIOS to keep it from throttling even on lower OCs like 135Mhz...

 

Thanks.

So I am finally ready to mod my BIOS I created the bootable msdos USB drive using Rufus, and my next step is to try and save a copy of my current bios (I have the W370SS). I could not save it using GPU-Z, so I am trying to use NVFlash, which appears to be included as part of your download.

The problem that I am having is, when I restart my PC and hit F7, I see the boot manager screen, but when I select the USB drive (which it does see), it still just boots to Windows. Has anyone else experienced this?

Edit: after doing some more research, it looks like I may have to temporarily disable SecureBoot. Has anyone else with Windows 8.1 noticed this? After flashing the BIOS, will I be able to re-enable that?

Edit 2: I went into the BIOS and SecureBoot is actually not enabled. Any other idea why, after selecting the USB drive from the F7 boot window, it still just boots to Windows?

 

Just follow the included readme >>> disable UEFI

 

Thanks for your response. I googled 'disable uefi' and that lead to a bunch of articles discussing how to disable UEFI secure boot. However, mine is already disabled.


Edit: Nevermind, I am a moron. I see the option to fully disable UEFI in my bios.

 

Just in case anyone is interested my FireStrike score is 4550 with a graphics score of 4951.

My core clock is 790 (+250) and memory clock is 1428 (+350). Voltage is maximum 1075 mV (inspector shows +6.3Mv) and temps max out at 66 (I do have a laptop fan running underneath). I've never seen the voltage reach the 'stock voltage' numbers that people are posting here. Still a little confused about this.

I am sure that I could OC further but based on some of the other posts here, it seems like it will be mostly diminishing returns past this. At some point I'll see how far I can go without artifacts, but in the meantime I am very happy!

 

Hey Prema!
Is it possible to to a BIOS for lenovo y50-70 to allow to OC gtx860m over 135mhz and get rid of that retarded throtling?

My BIOS:
LENOVO-9ECN26WW(V1.09).rom - Speedy Share - upload your files here

Cheers!

Oh, that sucks. =(
I need to wait then, maybe when I will have some spare cach i will contact You.

 

not sure if this has been covered but with my laptop I can no longer overclock with the latest drivers anymore.. MSI afterburner or nvidia inspector both do nothing.

 

latest nvidia drivers deactivate overclocking (347.09). Use 344.xx to get overclocking. I think it was just an oversight on nVidia's part, at least I hope so, otherwise we'll have to mod the drivers for overclocking too.

 

Should mention that this only affects mobile Maxwell.

 

I believe it affects desktop maxwell too..

 

Then why aren't various desktop forums blowing up about it? This notebook forum is the only place that has reported the issue.

Here, these guys reviewed a 980 that OC'ed just fine on 347.09: HARDOCP - Introduction - ASUS GTX 980 STRIX DC II OC Video Card Review

 

If that is the case, then hopefully just a glitch and will be corrected with future driver releases. They seem to do it every week now anyhow!

 

I really doubt anything is glitch when NVIDIA does stuff like this.. For AMD, it would definetly be one.. because of their useless programing..
