GTX 460M Overclocking

Oh I see. So I had to flash my bios to achieve those clocks? Well is there a way to guarantee that getting that V1 bios and flashing my bios won't brick my laptop? o.o

 

As long as you ask someone who knows what he's doing to mod your vbios, it won't brick your laptop at all.

 

I don't believe it will affect your warranty, but then again, I've just been taking some cleaning duster and spraying it in controlled bursts into the back vents and bottom vents. I haven't repasted either, but the highest temp I've seen was high 80's.

I set PhysX to force run through the CPU instead of the GPU and that seemed to help quite a bit though. Could that help? It's found under the nvidia control panel.

Also though, my last laptop was Dell xps 1530 (Was replaced multiple times for overheating issues)... So I might be overly paranoid about high temps.

Edit: Also, I had a quick question. I was running stable at 800/1550 but would randomly see screen flickers in Skyrim. Should I be worried that these are artifacts? In case they are, I turned my GPU down to 780/1510 and it seems to happen less frequently (maybe my imagination), but it still happens. In either case, I still randomly will find textures with green or blue spots..

 

If you see artifacts, then the problem can be split in two: either temperatures or vram chips design.
Not all the vrams chips can take a big oc, some of them struggle to reach 1500.
My old 460m was able to climb and stay stable up to 1600, but some users are stable only at 1480, i guess its your example.

So, if temps look right (82-85c) then raise the core clock back to 800 but keep vram clocks to 1480. See if that helps.
If it does, you may want to compensate the slower vram overclock by raising the core clock around 810-814, if it turns to be stable, youre good to go.

 

Yep, those are artifacts, lower your clocks and play games/benchmarks until you can't reproduce those "spots." Like said above, some people's vRAM can handle max clocks (like mine) but some others can't handle anywhere near as much (a gamble, I suppose).

 

Thank you both for the quick replies! I reset to stock clocks and lose about 5-6 fps, but its still very playable (35-45+). It's better knowing I'm not potentially damaging any hardware.

Thanks for the help!

 

First time OCing a laptop tonight (G73sw) and I came up with this: http://i903.photobucket.com/albums/ac239/powermapler/Overclocked1.png

I haven't actually tried going higher than this, but it works for me and it seems to be a popular clock so I'll stay here for now.

Anyways, I have a question. My temps seem to be all right, but do you leave your card overclocked all the time? Or only when gaming/benchmarking? I'm a little bit worried about long term damage, no matter how good the cooling on this is. (Much better than the JH, at any rate.)

 

Good OC! Yeah, with NvidiaInspector you can set OC shortcuts on your desktop, so I created a default shortcut and 780/1510 shortcut for gaming. I usually run ThrottleStop and then open up the 780/1510 when gaming and then go back down to stock clocks when not gaming.

Although, Skyrim still runs pretty great at stock so I haven't been using the OC as much.

 

Nice, I didn't know about those shortcuts. Thanks.

 

Well, I'm a bit surprised now. I've just successfully overclocked to 880/1760/1625. This is as high as MSI Afterburner will go. I've been using Heaven to test my clocks, and so far I've had zero crashes and no discernible artifacts.

Interestingly, my 3DMark06 score didn't really change.

EDIT: Are these temps considered high for the G73SW?

 

First off, you are using MSI software on an Asus.

NVIDIA Inspector is a better tool since you can unlock the min/max and push further. And you can manage profiles, and graph too.

 

That is a pretty high OC. That is the highest I have seen. Hope that is stable in games. I game on 840/1580/1680. It gas been very stable and I stay in the high 70's*F to low 80's on GPU intensive games.

 

Also I use Nvidia Inspector.

 

If you don't mind me asking, how the heck did you get that high? Did you overvolt?

I start getting red flashes at 800/1550/1600. Well, not so much flashes, but red-tinted lights as part of the 3dmark11 test. Even 780/1510 gives me some annoying screen flickers during Skyrim runs (not constantly, about one every 30-40 mins).

 

Inspector has the GPU clocks locked off. I may be missing something, but I haven't been able to use Inspector because of this.

I'm not sure. It just worked. Chastity handled an RMA on my laptop, and I believe he installed modified vBios, but don't quote me on that. All I've done is overclocked.

I don't get any artifacts or standard crashes due to temperatures, but I have noticied a bit of a problem. After running a game for 1-2 hours, the computer will shut down and restart on it's own. No error reports or anything. I'm not sure if this is due to the OC, as this has happened a couple of times on stock clocks. (Playing Skyrim and DX:HR)

I haven't seen GPU temps go above 82C.

EDIT: And yes, I've tested these clocks extensively in games and benchmarks, and haven't experienced any regular instabilities. So yes, I'd say this is stable in-game.

 

the GPU clock is tied to the shutter. move one and the other moves too. that is how mine works.

smellon- From what I have read the G73sw OC better the than the G53 for some reason. also no overvolting.

 

Ah, you're right. No idea why I didn't notice that.

What exactly the advantage of using Inspector over MSI Afterburner?

 

I experience some dips in GPU usage. For example, the frame rate usually hovers around 33 to 37 during a typical BF3 game, then suddenly the far rate would dip to 20 to 22 for about 5 to 7 seconds, then climb back up again.

It happens every 10 to 15 mins. Anyone knows what is going on? Thanks in advance.

 

Simpler, cleaner and doesn't limit overclocking.

 

That sounds like the CPU throttling?

 

So how do I fix that?

 

ThrottleStop. It's free and all you have to do is just run it. You can also close it immediately after, but I prefer to leave it open to monitor temps.

It's a neat little program.

Download ThrottleStop 4.00 | techPowerUp

 

I find that the GPU is the one that takes a dip during the drop in frame rate. Do you think it's still the CPU that's throttling?

 

Not sure, but it's definitely worth a try. What do the GPU clocks do during the usage drops?

I also have the G53 and it seems to help although some games, no matter what, give random stutters.

 

Maybe it's overheating? What are the temps?

 

Well, there doesn't seem to be a dip in GPU usage during Furmark 15 min burn in.

But the dip occurs during BF3. And the temps hovers around 77 degrees Celsius.

I am OCed to 775/1550/1550

 

I'd suggest you have some app monitoring and graphing the clocks and temps in the background so you can see what happens during the dip.

 

Just wanted to leave this here:

I feel enlightened. Thanks Smellon! You were right from the start.

Afterburner 2.0.0 Beta 6 (2010-08-12) Triple Over-Voltage - Guru3D.com Forums
Is it too risky?

 

Won't work.

 

I've got a 460m paired with a non-sandy bridge G73jw. My system will obviously vary from others as a result.

Last year I read all the various posts about OCing the 460m and had varying degrees of success, went back to stock, got board after awhile and tried it again, had problems, etc.

I don't know if this helps anybody, but I wanted to mention it just in case. The GTX 460m responds differently to OCing the GPU core frequency depending on whether you are playing a DX9 or DX10/11 game.

I originally had my memory clock at 1,500, but 1,600 is safe. Even if it can go higher, 1,600 is plenty for the average max core OC on this 460m. I set the core frequency to800 (which many would consider 'conservative'). Ran furmark for a while and the temps were in the mid 80s. Read that furmark doesn't do much on fermi cards except shortern their life and make them run hot. Anyways, no problem. Ran 3DMark Vantage and 3DMark 11. No problem. Ran Heaven through a few loops. No problem. Figured this was a safe OC, didn't really worry about going higher.

Played Dirt 2 and Crysis 2 for a while. No issues. Was getting at least 10%+ performance increase. Then I played Fallout 3, and oldie but goodie. Within 15 minutes, CTD. No big deal, that game does that. Or so I thought. Noticed the message in the taskbar that my nvidia driver recovered from a serious error. Played GTA14 for 20 or so minutes, CTD. Same error. After looking on google, it appears that this error message is definitely related to the OC. At stock, I never received this message.

So I tried 785. Same message. 775... success. Or so I thought. My computer would shut down after an hour of gaming like I pulled the plug. Now I have since determined that it is an overall heating issue for my specific non-sandy bridge i7 g73jw, specifically it has to do with the CPU. My CPU temps were in the 90s. That's within bounds and it does throttle down, but I think there is a tipping point or something.

So I settled on 750 for the core and again 1,600 for the memory. For whatever reason, this runs 5 degrees cooler. My CPUs don't get in the 90s either. Played Skyrim (DX9 game) for hours and also had no problems with other DX9 games.

My power brick is stock. I have not re-pasted the GPU. I did not flash the 460m's vbios. So I don't know if this helps anybody at all or if anybody cares, but the GPU clock frequency seems to react differently to OCing depending on whether the game is DX9 or DX10/11. I have no idea why but my guess is the overall GPU architecture is used differently. I get 12% better FPS in Skyrim over stock even with a 'low' OC like that. Pushing it higher has problems and the performance is diminishing returns.

Again, I don't have a Sandy Bridge i7, but I did initially have throttling issues with GTAIV causing the FPS to lower after a couple minutes. The problem no longer occurs but I have had a few bios updates and I do always have throttlestop running. My architecture is different though, so I can't be of any help there.

 

Despite my initial posts in this thread, I've found that if I OC too high, my SW will shut itself down whilst in select games. (DXHR, and Skyrim are the two big ones.) I'm not at my computer right now so I can't tell you my exact gaming clocks, but they aren't all that high. Around 800/1500/1600 IIRC. These clocks are still in their testing stage. No shutdowns yet, but I haven't done much gaming on them.

However, my CPU temps are fine, and I'm not getting any artifacts or crashed drivers - just a Kernel error in my event viewer and a shutdown when playing these games. I've heard that having a more powerful AC adapter can provide sufficient power to avoid these crashes, but I haven't tested this myself.

Not sure if our problems are related, but I thought I'd throw in my experience with this issue.

EDIT: Aaand, shutdown in Skyrim. Kernel-Power 41(63)

I'm going to play something else, and see if it's the game.

 

Is this a decent OC using afterburner?

Core Clock 850
Shader Clock 1700
Memory Clock 1600

Idle Temp 40C
Full Load 70-75C

I feel the card is able to put out a little more since i have all the bars maxed on Afterburner and the GPU never hits 80C.

 

That's more than decent, as long as it's stable. Try using Nvidia Inspector instead of MSIA, as you can unlock the bars and go higher.

 

This what I got...
800 / 1600 / 1600
Temp 70~80
Driver 290.53
With TS

3DMARK11 = 2311P. Is it good? (g53sw)

 

That's pretty high! Nice! Are you stress testing with 3dmark11 or a similiar program? Although the temperature is under control, keep an eye out for artifacts. Also, I believe the Memory and Core are supposed to be linked (Memory clock = 2*core)?

Should that be Core 850 / Shader 1600?

Yep! You could probably even go a little higher on the core. My shader seems to be stuck at 1550, but my core can reach ~830. I don't remember exactly, but this nets me ~2450-2500 in 3dmark11.

 

Umm... I'll raise the cores now, lets see if I can finish the 3Dmark test without bdos or somthing. (Although like 2 months ago I did 850 and 1625 and after 3 hours the GPU crashed... and with GTA IV every 5min crash.)

 

if you want to push core more than 850 it is the only way you should push the voltage over 0.912V which comes with initial.

I m using 855/1710/1625 last 3 months maybe with 0.962 and it has never crushed yet even in 3D screen all settings ultra in any game, only the fps is variable 3D11 was P2512 " it is my latest test with 290.53" so if you want to higher clock you should give a higher voltage via bios not with afterburner because it will not work.

max temp at full load 88C max and it is also quite acceptable,

and during the game play or bench. throttlestop also active

hope will give some idea

 

I saw that to in nvidia control panel and wonder if changing this will help when gaming
do you guys keep overcloked all time or only for games?

 

Hello everyone, need some advice.

Got Asus G53SW-XA1:
Intel i7 \ nvidia GTX 460m 1.5gb 192bit \ 16gb ram. \ 15" 1920x1080

MSI afterburner wont let me overclock shaders, only core and memory. Ive downloaded nVidia Inspector and have such OC parameters:
GPU: 810 MHz (at 820+ MHz video driver crash in Tera)
Memory:1500 MHz
Shaders:1620 MHz
Voltage: 0.912 V

Video Driver: nVidia 296.17 WHQL

My temperature at full load 92-93 C, but i had same temperature w\o OC.
While gaming my temp 82-85 C.
What perfect parameters for my notebook?

BTW, is it possible to manually force fan speed at max rpm?

 

GPU Core is directly linked to shaders, Core*2 = Shader clock.

92-93 seems pretty warm, what are you using to test? If Furkmark then that is ok since games will not put that much stress on the card.

Those are good clocks though. My most stable is 840/1540 or somewhere around there. I run games at 785/1500 though.

 

Hopefully someone can still help me in this old thread. I have recently got a laptop with the GTX460M and a i5-2410M.
At first I had trouble overclocking the gpu, the memory clock overclocked with no problem, but the core clock didn't go above 675MHz, I used EVGA, MSI afterburner and Inspector, reïnstalled drivers and all those thing.

Today I tried it again, for some reason overclocking the core clock worked, and finally I got much higher scores in 3dmark11. I haven't reïnstalled anything, the only change I have made is adding a laptop cooler with fans. But now when I have hit 840MHz core clock, the core clock is again locked at 675MHz, giving me again low score on 3dmark11. Does the temperature cause the 675MHz lock? Because the temperature has dropped back to 45 now, but the lock stays.

EDIT:
My temps never go above 80 degrees celcius

 

What program are you using to overclock? With NvidiaInspector, all you do is unlock, move the sliders, and click Apply Selected.

What levels are you overclocking to? Make sure you aren't just jumping straight to high clocks the first time, start out at the 780/1400 and go up in intervals of +10/+20 or so. Each 460m is different and has different stability. This also varies between games/programs. Once you find a good stable clock, then you can just immediately go to it.

If you overclock too high and your driver resets, it can cause the default clocks to lock.

 

llo!
That problem is not with the program you are using to overclock.
This is happening because you Exedendo be the limit of the Card.
so no error or fault occurs, the Video Card back the speed Stock and keeps locked until the computer is reset again.

do not try to go further doque can get your card.
I for example can stay stable at 810Mhz GPU
even so, in some games off the computer simply. is still a mystery.
More generally speaking, I can rotate several games without problems with overclocking.

with speeds up to 820Mhz my card hangs or freezes the speed to the stock

excuse my english! by Google Translate = p

 

I have the same VBIOS version came as stock version. I didn't flash it. What does it mean?

 

Well that's just the version it came with.
