460M Overclocking

So I have been able to succesfully overclock my GPU using Nvidia Inspector(830/1500/1600) however my temp on my GPU doesn't exceed 65C with a full load. I've seen on the forums where people can sustain 80C+. I noticed when I had my core at 850 it crashed and the max temp at the time was 65C. It reachs 65C with 830 core clock as well and never goes higher and is stable for running games(borderlands, skyrim etc). Is it possible that something is wrong with my temp gauge?

Every card doesn't OC equally. Some cards can do massive OC-ing on high and stable temperatures and some despite running very cool on a low OC, just will fail to stablize a higher OC. It is really in the luck of the draw.

In other words, there is nothing wrong with your temperature sensor, it is just your 460M just refuses to OC higher than 830 and unfortunately you just got a bad OC-ing card from the drawing bag.

 

A lot also depends on the ambient temperature. I believe it's a degree hotter or colder your room is affects the gpu temps the same.

 

yea the 460m and 560m runs very cool compared to the other cards like the 580m or the 6990m that are also available for the m17x r-3. The overclock atm that I use is 800/1600/1500 because it doesn't strain the card yet is as fast as a stock 560m. 850 is really high for this card. I can't pass 830 without having a crash. hope this helps out a bit.

 

I was really disappointed in myself for getting this 460M, after I purchased the laptop they started stocking the new m17r3s with 560ms and 580ms... and I've tried to call dell to get upgrade but those guys are about as worthless as the 460m to say the least. I suppose I should be happy to get 830 with the OC because I am seeing up to 20FPS increase in some games. (borderlands and Capsized) .

460m isn't a bad card, its just getting a bit old. Just wish my 6990m would work like it should

 

I'm pretty happy with my 460m even though it is a lower-high end card. I usually leave it with standard clock speeds, but once and a while I'll bump it up to 775/1550/1450, which gives me about an 8-10fps increase in Crysis 2.

 

ya for sure. 850 is very high for a 460m

The 460m in my Asus g73 runs 800/1600/1480 24/7 without issues and the temps are excellent.

Even 830 is good

 

temps aren't really a problem with this card. Its more of how fast the card itself can go. Mine can't pass 830/1660/1500 without crashing

 

I am 100% stable running 820-830 (850 benchmark) and I also can run maxed memory clocks. I get a very, very considerable increase in fps, and I don't get higher than 75C running Furmark extreme burn-in for 3 minutes.

 

that's not bad for a 460m...but different cards will clock differently. 830 is no slouch

 

I usually just leave it at 800 if I need to overclock at all. Only game that really needs the overclocking are Total War: Shogun 2 and the Witcher 2 at least that I own.

 

So if temps aren't a problem with this card, perhaps maybe it could be driver issues that crashes my games? When I overclock to between 840-850 I do not notice any artifacts or funky visuals going on, it just simply exits and the driver fails. I'm the type of person that likes to experiment no matter what kind of consequences I may have to face.

Even when I overlock my card to play witcher 2, I see absolutely no FPS increase at all. On witcher im running at the lowest possible settings and still only get 15-20 FPS, very disappointing. What are your settings ?

On skyrim I just turned off vertical sync and I can run ultra now(the screen tearing isn't nearly as bad as I thought it would be) and get 30-40 FPS in big cities and 60-95 FPS outside and around skyrim.

Right now I'm deployed so when steam did its stupid update on shogun 2 I had no choice but to unistall because the internet was too slow to finish the update. This made room for skyrim(installed from cd) however I would of liked to try overclocking on shogun... how well did the OC work on this game?

 

increased the frame rate a bit for shogun 2. I can run all my games maxxed out (witcher 2, medal of honor, MW3, skyrim etc) and get at least 30fps. only game that has problems is shogun to and I can only run that on high even on my smaller 900p screen that my r-3 has. have you tried whitelisting games? that might help with the witcher 2. Just follow the guide in my sig

Edit: forget the whitelisting it only works for non-3d models because we have to deal with opti-mess

 

What is your actual voltage on Dell 460m ?

With the modded vbios, voltage up to 1v, really good overclocking for gaming:

865core/1730shader
1650memory

It gives quite a boost, about 15% more performance than 560m.

 

dang how did you overvolt the card? I would be tempted to try this but I think this machine is getting replaced with a new one soon

 

The voltage on my 460m is .95 atleast that is as high as it will go in Nvidia inspector. I don't know exactly what to do to increase the voltage higher than that?!?

 

you gotta flash the card with a modded v-bios I believe. Something I have never really looked at doing before.

 

Can anyone expand on this? Likw, what modded v-bios are we speaking of?

I've been tinkering with OC'ing my 460m and noticed the voltage is the same .95 (max).

So far (w/3D disabled) i'm gettign best 800/1500/1600 testing Batman AC and Trine 2. At 830 I start crashing.

 

yea that's about the max on my card as well. Google how to over-volt the 460m and I bet you will find an answer on how to do that.

 

http://forum.notebookreview.com/sager-clevo/539355-over-volting-gtx460m-2.html

thats about all i have found. Dunno how to flash that to the card though. or if it even works.

 

The memory clock matters more here than the core or shaders in all honesty.

It's the reason why the 4890 still beats a 5770 despite having the same core clock speed, same pixel and texture fillrates. Look it up. The reason why the 4890 passes the 5770 is because of it's higher bandwidth. Heck a 1GHz core 5770 only just matches a 4890 at stock.

Even with a lower core clock, my 460M, passes a 560M @ 750/1500/3200 and matches a 470M. Bandwidth matters more with these lesser cards.

 

hmm ill have to do some more testing then and max my memory clock

 

Can you explain why the memory clock is more important?

 

I think as simple as it can get is:

Despite however fast your core speed is, processing the data. The data itself must be put onto the vram, then the display. The quicker the memory, the quicker the data gets pushed to the memory then onto the display thus allowing the core to perform more efficiently.

 

Thank you for clearing that up a bit.


Does the 580M run signicantly better than a 460M? Also, how well does a 580M overclock, I am thinking of upgrading in the near future once a find a place to get 580M.

 

Yeah the 580m is almost twice as quick as a 460m. And it has much more overclocking ability. I get around 18k GPU score in Vantage OC'd. When I had the 460m, I got around 8k.

 

wow...... my system is getting old :O

 

460m is still a high end card though I think those scores in my sig are all I'm gonna get out of my poor 460m.

 

So I've been playing around with OC'ng my 460m. Using Afterburner and testing 800/1600/1480 settings. Runs smooth and Max temp I've seen logged is 78, averages 77..

But I am observing one problem. I can be playing fine for 5minutes or so.. then frame rate drops incredibly and stays that way for roughly 1min then frame rate jumps right back and things are fine for another 5minutes or so. Everytime frame rate drops it does so for the same amount of time, roughly 1 minute by my watch. Doesn't matter the game either as I've tested several. GPU temp is around 75/76 when this happens so not sure if that is the reason or not as I've read that anything below 80 shouldn't cause any issues.

Does this sound like a typical symptom of overclocking? Or is there something else I should be adjusting?

Anyone with thoughts or suggestions?

Thanks

 

I get around 65C when I'm maxed overclocked for the benching runs. You might wanna do a repaste. As to the throttling you are seeing, mine will throttle if I hit 78C, though I've only had that happen when I blocked the vent intentionally during a furmark run

 

I see. I've seen the term 'throttling' tossed around in other threads, wondered if that is what would be described here. Thanks.

 

the GTX460M/560M are cool cards. I OC my GTX560M to 920/1840/1600 when playing Skyrim or benching and have only hit 63c. 3DMark Vantage comes in at 12456. At 941/1882/1625 temps rose to 65c and 3DMark came in at 12671.

 

Sorry to bump an old thread, but just wanted to respond in case anybody else is in the same boat as I was. I have an Asus G73JW with a GTX 460m. Had it for over a year now. It's been mostly fine except for some random freezes throttlestop corrected (from switching C states) and a random shutdown only experienced from overclocking.

If anybody has a GTX 460m still and cares at all, do not play with your memory clock. If you do, do not increase it much. imglidinhere is incorrect in stating that the memory clock is the most important. PC overclockers already know this. A small increase in core/shader will give you significantly better fps than a large increase in the memory clock. The bandwidth does not matter, even if there is a bottleneck you are still getting higher performance overall. Too much misconceptions and self-proclaimed experts who don't realize they don't know what they are talking about.

I have my 460m at 810 core and 1260 memory. That's 10mhz, yes 10mhz over stock. I had it at 1500 and 1600 and this caused the shutdown due to heat. My GPU is now 10 degrees cooler and 72 degrees is the absolute max under the highest load after over and hour of heavy gaming with no shutdown.

So if anybody has that issue, a repaste won't fix it. Neither will a new power brick. And it isn't drivers. It's overclocking the vrm. Don't do it.

 

hasn't done much to mine and I leave at 100% load for hours at a time doing F@H. my clock speeds are 820/1640/1540 and have never had any issues. I usually run stock unless im doing doing running a game that needs the extra fps, benching, or folding though. Usually my temps are between 55C-60C at max load so temps aren't an issue. Not really worried if the card dies either because if it does die, I get a free upgrade to a 560m or 6990m depending on what happens.

 

i have a 460m in an Asus g73 conservatively OC'ed to:

800 core
1600 shaders
1480 vram

Its solid and most people overclock their ram to at least these numbers without issues. Even at these numbers, the 460m runs cold. So i'd venture a guess that its something to do with your card

 

Could it be that the vram chips dont have the same pad like the alienwares do under the vram? Just a thought.

 

when i was use the gtx460m,i had this numbers:
815 clock,1850 memory,1600 shader.
and my max temps where 60-61,very stable.

 

It's an Asus issue it turns out. Raising the memory clock from stock did contribute heavily to my temps with almost no perceivable benefit during games though, so I left it at stock ever since just in case it did overheat.

With the 301 series drivers, I can't go above 800/1600/1250 without getting the driver to CTD after a little while. Tried 850/1700/1250 and temp almost immediately shoots up to the 80s and it freezes after 30 seconds.

But the Asus has a shutdown issue that manifests very quickly at 800/1600/1250, seems to be even worse with the 301 series driver. Certain games like Skyrim shutdown in 5 mins with this driver, used to take an hour. Ran at 775 and it shutdown after an hour. Now I'm just using stock and experimenting with 750. Even stock shutdowns for us on occasion. Rare for me, but it happens. If 750 doesn't last as long as stock, then I give up on overclocking this Asus G73.

Again, it's an Asus problem. I've re-pasted and temps are great, like 74 at the highest. No artifacts no CTD no freezing. But there is a shutdown problem that's likely related to power and the motherboard and a higher voltage power brick won't cut it. Judging from the archived messages here, it seems to affect every Asus G53/G73 regardless of CPU or even video card. So don't worry if you don't have an Asus. My laptop is getting old anyway, but the newer models don't impress me as they are merely a modest update of what I have, I was waiting for 2x as good at least. Now I'm thinking class action lawsuit for Asus.

 

Sorry to hear you never got it fixed. You could grab an alienware with a 7970m If you want speed. It's got like almost double the power of a 6990m which is 2x as fast as a 460m.

 

Dude, my 460M couldn't push higher than 735/1470/1550.

Don't talk to me about poor overclocking capability. I'd have killed to push my 460M to his clocks.
