Do all Quadro NVS 140M GPUs overclock this well?

I just OC'd mine from 400/600 to 701/955 and it's been stable in the NV stability test as well as a couple hours of Counter Strike Source...that's a 75% overclock on the core, and basically brings the 140M to 8600M GS/GT levels.

Are these workstation chips cherry-picked or something? The 7600GT in my desktop never even came close to this in terms of OCing ability.

 

300mhz overclock on a notebook vid card?

Unpossible.

 

That's what I thought too...but both nVidia control panel and RivaTuner report 751/955 speeds...and it was fine after 1.5 hours of CS:S too...

 

You can do a search on the overclock abilities of the 140M. I know a few members here on the Lenovo Forum have overclocked their 140M's pretty high and getting impressive scores. I've yet to read anything bad about them overclock-wise.

 

I just overclocked my settings to yours to test them out... but my stability test keeps erroring out or something...

Is it safe to run at such high settings?

 

What are you temperatures at those clocks?

 

also, have you benchmarked those settings with 3DMark06?

 

The NVS140 is probably highly binned for good power consumption, which means it will also run at good clocks if you are willing to risk the power consumption.

 

You can see my temperatures on the monitoring program in the top right corner...69C about 20 minutes into the stability test.

It gets a bit hotter in CS:S, but the highest it's ever gotten was 82C at a LAN (where the ambient temp was pretty hot due to 15 computers being in the same room).

Not yet, but it was stable after a few hours of Counter Strike. I'll get 3DMark today or tomorrow and test it out.

 

what drivers you are using ?
i can overclock my nvs140 to similar settings and its stable.

 

T61, T7300, 2GB RAM, Quadro NVS 140M

Running RivaTuner 2.09, with on screen Temperature reader, and Forceware 169.04 from LaptopVideo2Go:


3DMark06:

400/600 (STOCK) - 1810, 75-80 C

600/800 - 2394, 75-80 C

600/900 - 2477, 77-88 C

675/925 - 2639, 80-91 C


All stable, yet the higher temps are obviously more dangerous.

 

It's hard to believe how well it can OC. I think it is because of how small of a bandwidth its interface is. So even though the numbers are high very little juice is actually flowing. Just somthing I though it could be, not certain.

 

to anyone who has tried this, what is your GPU temp at stock settings?

 

I'm just using the newest Lenovo NVidia drivers. My temps between stock and OC'd aren't much different. I run a dual boot config on my system, and the graphics card is stock in Vista, and OC'd in XP when I am gaming. I haven't noticed a big temp increase, maybe 5-10C at most.

The performance is DEFINITELY noticeable though. At stock, I couldn't even play Counter Strike Source at 1440x900 with low details and NO AA/AF. With OC, it plays fine with all HIGH details and 2x AA/4x AF.

 

nVidia stability tests all passed but crashed after 30 mins on Crysis at medium graphics settings.

 

I think it was Sonda5 who got 6000+ points in 3Dmark06 with his FX570m:O

Keep in mind only those temps are only representative of the core clock and not the memory! Be sure to run ATI tools artifact scanner too.

 

the nTune tests are useless, not a good indicator

 

mine's overclocked to 648/900 by RivaTuner. I did some mods, like putting another thermal compound on the GPU and the CPU, so now max I get 80 deg C.

http://forum.notebookreview.com/showthread.php?t=286257

but how do you get performance settings on your nVidia Control Panel ? .. I don't have those .. and use last driver from Lenovo.

 

I just spent some time overclocking my nvs 140m in my
Dell Latitude D830
Intel T7500 2.2ghz
4gb RAM
using latest 180.43 drivers from laptopvideo2go.com

Be sure to use new drivers because the standard drivers are more business application oriented.

I did some research and learned that the nvs140m is probably the geforce 8400m g or gs.

NOTE: the overclocking page in rivatuner correctly displays the components' clocks; however, the hardware monitor in rivatuner does NOT display the correct clock speeds. Use gpuz to get your actual operating clock speed.

I used rivatuner. the stock specs for the 140m in my dell are:
core clock:400mhz
shader clock:800mhz
memory clock:400mhz
idle temp :63C
peak temp during 3dmark06:79C
3dmark06 score:1583

first overclock:
core clock:465mhz
shader clock:930mhz
memory clock:465mhz
idle temp :66C
peak temp during 3dmark06:83C
3dmark06 score:1839

second overclock:
core clock:500mhz
shader clock:1000mhz
memory clock:500mhz
idle temp :67C
peak temp during 3dmark06:85C
3dmark06 score:1593(see conclusion for explanation)

I noticed that COD4 played much better than stock with the 465/930/465 overclock. frames per second(FPS) improved quite a bit. Considering the fact that the stock load temps are about 79C and the 465/930/465 overclock had load temps around 83C this seems like a safe overclock to me. I think it would be an excellent choice for the long term.

Something strange(and comforting because I don't want to burn my gpu up) happened on the second overclock of 500/1000/500. My 3dmark06 score lowered! I was perplexed until I pulled up my rivatuner hardware monitor showing gpu temps and clock speeds. about 2/3 of the way through the 3dmark06 test the clock speed dropped drastically! I noticed that at the same time the gpu temp had hit 85C for the first time during the test. 85C must be the gpu's automatic safety trigger. At 85C the gpu automatically cuts the settings back to 200/xxx/200 for a specified amount of time.

So, for a safe long term overclock I would do an overclock that will keep load temps from reaching 85C. I'm going to try running 500/1000/500 playing COD4 because the game may not push the card up to 85C. However if the graphics card does get too hot, I'll drop my overclock back to something closer to 465/930/465.

hope this helps the rest of you guys out. let me know if you have any questions.

 

^ well yours idles at 63 deg C ?? .. where as mine idles at 48-50 deg C

so check your fan or something.

I'm using our stock driver, which is version 179.74 or so at the moment, and the card has been overclocked for quite some time now, and no problems what so ever.

the max temperatures I've hit were like 87 deg C, and I played C&C 3 at the time for maybe 3 hours with that hot GPU, and still no problems. Then I put some other thermal paste and lifted the laptop on stands about 1/4 inch high, and now max it hits like 82 deg C or so, still no problems.

I'm running 600 core and 900 memory, with 3DMark06 score of 2300. And my laptop is smaller than yours

 

yeah I was kinda surprised my idle temps are so high, but my latitude's fan sucks. I just ran 3dmark06 again with the fan manually turned to high and I was able to get through a whole test 500/1000/500 and get a score of 1977.

how safe is it to run 600/xxx/900? if I got my temps down do you think I could run that for at least the next 2 years?

I wonder why mine cuts out at 85C but your can get to 87C?

oh and I don't care if your laptop is smaller than mine because my ***** is larger than yours.

 

so I tried cod4 with the 180.xx driver and it repeatedly crashed on me. had to go back to the 179.xx driver.

also running the 500/1000/500 in COD4 hit 85C so I had to drop it back to 465/930/465

 

because you bought Dell .. that's why

I said that my laptop is smaller because I was trying to say that yours should have better cooling abilities since it's bigger, but now I don't care .. hope you burn out your GPU

 

every time I click APPLY when I modify something it just resets back to 400/600. dpoes anyone know why?

 

hmmm you know I had that problem before. I don't remember what I did though. I think it just went away? try restarting or reinstalling rivatuner maybe? I think mine was just freaking out for a little bit though.

oh and an update. maybe cooler fall temps are responsible, but I can now overclock my core clock to 500mhz with no problems.

 

update: I started running TPFanControl .. so now I max out at 71 - 72 degrees or so, but that's because at 70 deg C my fan switches to crazy speed of 4600rpm, lol, the 64 setting of the TPFanControl.ini .

sooo, I may overclock to 700 core now, lol.

P.S. I dont undervolt the CPU yet. I can, but don't.

 

lol

it works on 650 core now but I left the memory at 900 (even that it works at 975 too)

I think I'm done with it. At 700 core it freezed .. and at 1000 memory it gave errors

so 650/900 will be it, since yesterday. TPFanControl FTW -> 71 deg C max always

 

and here are some 3DMark06 scores:

650/900 - 2385 marks (50% overclock)
650/950 - 2423 marks
650/975 - 2436 marks (62.5% overclock)

today, I'm using the 650/950

 

Two quick questions:

1) How are you raising your core clock beyond 600? Rivatuner's slider ends at 600 for me. (Likewise, how do you get memory past 900?)

2) I'm assuming that you're letting Rivatuner set the shader clock automatically, at double the core clock value?

 

1) go to power user tab, select RivaTuner\Overclocking\Global, type 100 for value. Check your overclocking values

2) yes, shader is 2x, ot 1300MHz

 

Awesome -- thanks!

 

So, at an overclock of 675/975, I get a 3dmark06 score of 2823 with a high temp of 72C, according to the Rivatuner monitor.

Pretty amazing difference from my stock score of 1908.

I've got to ask again, am I damaging my GPU by doing this????

 

Just to say there must be 2 types of 140m since the T61 has the card with 600 mem clock stock while the Dell D830 has a memory stock of 400 and can't overclock as much as the T61... Dell is to blame for its underpowered 140m

 

That's the difference between the DDR2 version of the card and the GDDR3 version. Not a huge difference between them performance wise, but the GDDR3 version should see better results from overclocking as you say.

Highest GPU Temp 73C

Running Windows 7 x64 build 7048 with 182.08

600 core 500 memory, (Rivatuner shows wrong clocks for some reason)

Ran with 650 core and then got 2185 3D Mark. Idle Temp now 45C with Laptop cooler and usb fan XD running on external power to reduce voltage hogging.

 

Nice score.

I really havn't tweaked my wifes' R61 very much.

Because it is hers.


However after a little tweaking I did get a decent 3dMark06 score out of it. (in my sig)

Also it does a good job with folding@home.
