Nvidia GTX 460m overclock

I can't seem to find an article or review for overclocking the Nvidia GTX 460m mobile graphics card. Google only comes up with articles for the GTX 460 desktop version. Can someone link me to a good informative article or review on this?

 

I've been able to get up to a stable OC at 825/1420 with the shader clock scaled to the core.
It's on an ASUS G53Jw, and temperatures from FurMark stability test tops out at 91C, idle at 48C, no throttling.

In 3dMark Vantage, I got an increase from 7425 to 8084-8525 (varies a lot).

 

Forgive me, I'm noob to overclocking, but 825/1420 would be memory/shader? how long have you had these settings? and is it safe for everyday use? Also did you do it through Nvidia control panel?

 

Nope, the shader is at 1620MHz. I'm using MSI afterburner, so it's:

Core - 825
Shader -1620
Memory - 1390 (reduced a bit, since 1400MHz+ is a bit too much for 1.5GB VRAM)

And I haven't had any issues, no artifacts, etc.
And I believe that the GPU auto-downclocks to 200MHz when not using it intensively (web browsing, etc.) and I haven't had any BSODs or any GPU throttling.

 

It's not the amount of ram or even type of memory chip that holds back the memory clocks on the fermi based arch. Its the ability of the memory controller to handle the higher speeds, since its been designed for width and to take up as little core space as possible it reaches limited clocks.

ATI uses a narrower memory bus containing less memory controllers (mob 5870 was 128bit) but they are more complex and can cope with a higher speed of memory.

Also you have two options.

You can either call it by its real frequency (695mhz) this is the most honest approach. Or if you are going to talk data rates then times it by 4, since its GDDR5 which transmits 4 times every clock so 2760mhz is the less honest answer.

 

I currently game at:
core: 825
Shader: 1650
Memory: 1450

without any problems at all. My card tops out at 78C on Furmark extreme burning max everything and idles at 44C. I'm currently running the nvidia beta drivers 266.35 if that helps at all. Basically if you're wanting to improve the FPS in games but not try to max out the card's potential, i would stick with the following clocks:

Core: 800
Shader: 1600
Memory: 1400

and you will be fine. Good luck and let us know how it turns out! I also use MSI Afterburner to overclock.

 

So is 73-75c @ 800/1600/1480 ok then? I can get it up to that point stable, but the temperature is worrying me some.

Is there a temp I should be trying to stay under?

 

85-90C 10char.

 

you don't need to start worrying until you hit up to 90C or above. You are completely fine!

 

@bstapley how come you aren't using the WHQL 266.58?

 

^^ Na. Depends on the notebook.....If you are running it in a Sager / Clevo or Alienware, then yes...I would start to worry around 85C-90C. If you are running it in a asus g53jw, there are multiple people who get in the low 90's C running furmark. If you look even farther back to the 260m and 280m in the Asus g51 models, they would game at 90C or above EVERYTIME you play any game. I would know because I used to have one. So...what's my point in saying this? The chips are rated for up to around 105C (cant find the link with the top temp rating sorry) and then you will fry it.

Also, if you have a new 460m in a laptop, it will come with at least a 1 year warranty so if you do happen to destroy the card while playing at 80C (won't ever happen) then you will just get a new GPU from the manufacturer. So no you do now need to worry about it getting to 80C or even 85C. I am going to stick to my guns and say 90C is where I would get worried.

 

I have an m15x with the gtx460m ..... I run pretty much everything but a few games maxed out, but am intersted in giving overclocking a shot (will be my first time). Is MSI afterburner a generic program that works on any brand computer? Is it my best option for my alienware?

 

yes it should work just fine. let us know how it goes!

 

Which one is better?
NVIDIA System Tools
MSI Afterburner
NVIDIA INSPECTOR Version 1.9.5.0
ATITool - Overclocking utility for ATI and NVIDIA cards (Not for Win7, exclude it from the options)

 

For some reason Nvidia inspector doesn't seem to work on my Toshiba X505, the core clock is grayed out, but Nvidia system tools, did give me the overclock option in the Nvidia control panel so that's what I use.

 

Thanks for the recomendation!

 

In NVIDIA Control Panel I can only see
- Graphics clock: 570
- Memory clock: 1250
- Processor clock: 1140 (grayed out)

When I change graphics clock, the processor clock will be change too. Which settings should I use to increase the performance with the temperature is under 78-80c?

Thanks a lot

 

In the fermi architechture the shaders and core cannot be unlinked, there are at a fixed ratio so that is normal.

 

weird that your stock clocks are different. I believe graphics would be core which mine is default to 675. Processor would be Shader, which is linked with the core and my default is 1350, but our memory clocks are the same at 1250.

The overclock I'm using is 800/1600/1480, (graphic/processor/mem) maybe you could try that? I'm copying it from someone else who has the Asus with 460m and the highest temp I get while gaming is 71c.

 

The reason his clocks are different is because Alienware changed them in the M15x, they are standard clocks in the M17xR3 but gimped in the M15x. AW is pretty known to do crap like that but the card still overclocks very well. I'm running at 820/1640/1500 in my R3 but I'm starting to get really ticked as it seems all of the 460m's have locked voltages in the Vbios where they can't be over-volted for even better clocks.

 

Yes it's pretty freakin lame that we cannot overvolt the card! I was just reading up on that last night before bed...and basically teh 460m's cannot be overvolted using NiBiTor. sad......

 

Didn't some guy send this GTX 470M BIOS to mvktech.net and got his card overvolted to .99v? Here's a link to the thread:

http://forum.notebookreview.com/sag...-benchmarks-sager-np8690-clevo-w860cu-29.html

Re:mySN XMG P701 with GeForce GTX 470M any device tweak!? - MVKTech Support Forums :: mvk.tech :: NVIDIA GeForce GTX 580 570 560 460 ATI Radeon HD 6970 6950 6870 5970 :: MVKTech :: On the Edge of Technology

Maybe he can help with the 460M BIOS.

 

Yes he did, but from what I've read on mvktech.net, the 460m has some sort of lockout on voltages and other features. I've actually sent in my 460m bios to those guys and they told me the same thing. Tears swelling.....

 

Yeah I've been contacting Mavke the guy that does the programming and help with that site, NiBiTor, and a few other things and it's not that the voltage is locked out it's that for some reason the Voltages don't read at all they don't show up in the VBios in any way.

 

So is anyone else running stable overclocks that they use on a daily basis or even set as default? I'd really like to know for how long now, and if any sort of problem has reared it's head.

 

I'm using 800/1500/1600 every time I start up a heavy game (highest temp I got is 73-74c). You can create a policy in NVIDIA control panel and set event to automatically launch that policy when you start a game as well as return to default stock clock after exit that game

 

Thanks for the advice. I remember reading somewhere that there's a program that will reset your overclocks to default at the moment it becomes unstable, (i.e artifacts, overheat, etc.) while gaming or running some kind of stress test. Do you know anything about this? I'd sure like some kind of safety net that'll will do this automatically before I cause permanent damage. BTW I'm assuming your overclock of 1600 refers to the memory, if so I read someone saying that 1400 is a little to high for, I think he said GDDR5 memory, or something like that. Can you elaborate?

 

Don't worry jacob. If it become unstable you'll notice it. Or the card will and throttle or crash on you.

 

aha, so it already has it's own built in safety net, but each time it crashes from to much overclock, will it be doing damage?

 

jacob, if you keep ignoring the crashes and continue to run it at those settings then yes it will. Just take a BSOD or NVDL error crash or any sign of trouble very seriously.

IOW if you just restart and play until it crashes. And you do this repeatedly then you will kill your GPU.

 

Hey guys, just tried overclocking my 460m with msi afterburner, but for some reason, even after hitting "apply" the graph does no show a change in any of settings. For instance, I set 825/1650/1450 hit apply, then hit save, and set it to profile 1. The graph did not change, the min/max for any of the settings did not change, and I tried testing to see if Dragon Age 2 ran any better, and the FPS is literally unchanged from default to those clocks. Is msi afterburner not working, or am I doing something wrong? If you must know, I was running Dragon age 2 on directx11, high graphics quality, no AA or AF, vsync on. The FPS remained from 38-52 FPS depending on the area, with no differentiation between default and overclocked settings. Any ideas?

 

yep same here, MSI doesn't work for me either, so I just use the built in overclock tool in the Nvidia Control Panel, works like a charm and so simple...

 

I have MSI Afterburner had it works fine, what laptops do you guys have? My clocks are in my sig, dead stable and cool.

 

the overclock tool doesn't show up in my nvidia control panel ;O Oh and I have the new GT680 that just came out

 

you have to install nvidia system tools for it to show up
NVIDIA DRIVERS 6.06

 

i overclock with this tool very usefull and no install.
NVIDIA Inspector 1.9.5.5 Available - 3D Tech News, Pixel Hacking, Data Visualization and 3D Programming - Geeks3D.com

 

So the nvidia control panel overclock works I think, but there's no option to change the shader clock, just memory and core

 

shader is linked with the core cuz of the architecture of fermi.sorry for bad eng.

 

Okay cool, then I'm a happy man. The overclock seems to have boosted my FPS on dragon age 2 by about 4-5 FPS. Now I can play smoothly on directx11 high settings!

 

I'll be doing some overclocking to the GTX 460M that I have in my MSI GT680 (that I got in late January). I did some small overclocking experiments when I first got it, but I don't remember what the results were.

 

hi guyz :

I have a problem to overclock my GTX 460m : i hope you will resolve it cause there is 1 week i m looking for it.

When i set my o/c (to 745/1490/1500) with MSI Afterburner, then clicking "apply", nothing is done and all values come back to the factory values.

When i try it with nvidia control panel or ntunes a box tell me that my values are not ok and will not be effective.

So i can't o/c my card by anyway i know and it's a problem cause at the moment i only have 570/1250/1140 and lot of lag in games.

I have an Mx15 with windows 7 64bits and the last official drivers (280.26)

Any idea please ?

 

this card in my g73 overclocked fabulously...

i was running 800 core /1600 shaders /1480 ddr5 and it was still capable of more...

every 460m should be capable of at least these nnumbers

 

what do you mean nothing happens? Once you set the numbers in afterburner, they don't stick? even while the gpu is stressed?

 

I mean that the values rollback to their original place (so factory values), and these ones i had set before are not effective. Each time i've tryed to change them it was the same.

I've try to save the o/c values before apply them : same thing i come back to the factory ones and when i click again on my save nothing move.

I know it's possible to o/c the 460m but i don't understand why mine don't want apply the changes.

 

That's rather odd, it's probably driver related issue, have you tried to uninstall your drivers and then reinstall?

 

I would try first do completely wipe the driver from the system, then install the latest one.
Follow the guide in my sig, it should come handy.

Then use Nvidia Inspector to manually raise your shader/memory clock. I would try first with 800/1600/1500 and after set the clocks, click on "apply clocks and voltage settings". The settings should stick now.

Forgive MSI AB until a new version comes out, its no use, unless you use the latest beta 2.2.0 beta 8. But that should be an option when youre sure that you can oc your card without trouble.

Also Nvidia System Tools is no more mantained althought nvidia keeps mentioning it into release notes. Stay away from it, unistall it if you have it installed. Its known to cause more trouble than good things.

 

i just did all you have wrote. Pilots just installed. I run inspector and set the clocks to the values you wrote. I click "apply clocks and voltage" ..... and nothing was apply. All settings come back on their first setings (570/1140/1250).

I m sure i did all you advise me nicelly but don't works ;(

hmm, maybe your overclock is too high for your card to take? It might be fine for other people's 460M, but not for yours? I have seen things like that before when people take the clocks too high and too fast, then GPU clocks will simply revert to its default value immediately.

You can try to give the 460M a small overclock, say 50/60/50, stress test it with benchmarks and alike, then take it up slowly by a small increase like 70/90/70 , then test the overclock again and see if it's stable, keep doing this process until you encounter an error(like BSOD, artifacts, driver crash, or GPU clocks return to default, etc).

If you can't even overclock it by a very small amount, then I suppose there must be something wrong with your card.

 

I know this is old post but thought I would offer insight in the ocerclocking issue, reinstall the drivers from scratch when I did that it overclocked fine, mine did the same thing as before and my card seems like its in perfect condition, once I reinstalled it worked fine

 

I try to make overclock with EVGA Precision X 4.0.1, i change core from 709 to 750 mhz and it seems that my clock is stuck at 675 mhz! I do something wrong or the software is reading wrong frequency?
Also i installed MSI Afterburner and the same result: 675 mhz core,despite the overclocking that i applied (750 mhz).
Another weird thing is that factory clock is at 709 mhz (show in GPU-Z),but again the monitoring softwares that i use shows only 675 mhz!
What is the problem with my GTX 460M?...Is there really a problem with my card or is just an reading error?
Thank you!
