Overclocking the GT 540M

fps_max 59 odnośnie optymalizacji csa to wiem co i jak i co jest grane

As you can see, temperature is a problem. 95C - low performance. 85C - optimal performance.

 

After doing some reading through this thread and experimenting of my own, I'm a bit disappointed in my results!

I was crashing just yesterday at 770 core, 900 memory with my 540m. So, I backed down to 750 and tried again. Crashed again! I know every chip is made differently, but I was expecting a bit more since so many others with the same chip are having no trouble overclocking to 800.

Is there anyone running an l502x right now with a 540m overclocked, on the current graphics drivers and latest BIOS? D:

 

Try using 960/960 settings, don't forget to use the Intel Turbo function

 

ok, I've got my laptop back, problem was dust and this...



3Dmark06 1024x768 stock clocks GPU: 9354 points, temp max 75C - earlier was 95!!!!!!!!!!!!!!
3Dmark06 1024x768 clocks 770MHz (Core) oraz 950MHz (memory): 10557 points, temp max 84C - earlier was 95C, and emergency auto shutdown

 

@biowulff 960 core / memory? Yikes that seems high! Or maybe the 750 to 800 range is a "weak spot" of the chip? Tune down the CPU also? I can do that, but is the reasoning for temps, or power, or a combination of both maybe? Just curious

Edit: Now at 740/960, stock voltage, and ~70C. 750 causes me to crash regardless of memory clock.

However, I'm leaving the cpu to full power. I have gotten an x124 BSOD report after rebooting at least once after a crash....so I guess I'd have to tone the CPU down if I want to up the GPU?

 

It really depends on the software/games that you are using with those OC settings. For example, I can play sleeping dogs on 800/960 settings but if I use 960/960 settings it will simply crash. I can use 960/960 for Assassins Creed Brotherhood without any problem, it really depends on the game that you are playing. Max temp is 89/90 degrees at my system on full load.

 

I must have a pretty bad card, can't even hold 740 without one of my games crashing Haven't had the time to test other games for very long yet, but GTA IV seems to do better with an OC.

 

Dont forget to use an cooling pad, people!

 

Hi Guys,

Very first post here, let me begin by saying thank you for all the great information contained within these 56 pages!

I bought myself an XPS (L502X) recently and have loved every minute of owning it. I've never had a decent laptop before and this machine has converted me from a console gamer of 20+ years to PC gamer.

Anyway, my favourite game is Mass Effect 3, and I was delighted to see this laptop could run it even better than the PS3. However, it wasn't long before I wondered if I could attain a decent FPS at 1080p (I hook the XPS up to my Panasonic plasma at home when possible). Out of the box I got okay results with the graphics options off, but it was still a little choppy. So I began looking at what I could do about it. Believe it or not, I'd never heard of OC, and was a little disappointed when I read I couldn't replace the 540M with something better.

But then I found this thread.

After installing MSI Afterburner I've been gradually tweaking the speeds, and last night I'm happy to report I attained my goal! ME3 running in 1080p on my TV at a framerate of 30-40. Yes!!!!!

The settings I've been using for this are 780 / 980. I played the game for around 90 minutes (3 rounds of multiplayer) and afterwards I checked my graphs etc for temps. Peak was 76 degrees, my CPU was at 85 degrees (but it runs at the exact same temperature on the base clock settings) and I didn't experience any graphical glitches etc. So I think it's stable...I am an absolute beginner here, but hopefully that sounds okay to you guys?

So thank you again, everyone, for giving me the knowledge and confidence to tweak the GPU enough to reach my goal. Now I just need to stay away from further tweaking!

In case anyone is interested, the ambient temperature here is fairly low (prob around 17-18 degrees at the time of the test) and I use the CoolerMaster U2. I've aimed the fans at the vents on the bottom, although wonder if I should instead move them to the hottest points instead?

I also ran 3DMark06 a few times to get a more objective measurement. My base result was 8972, and my best result was 10061 using the clock speeds above.

 

what resolution while testing on 3dmark?

 

is there a way to force the gt540m to a certain voltage.

According to nVidia inspector the voltage doesn't go up to 0,98v and keeps at .85

BF3 keeps crashing because of too little voltage

 

if you have a l502x, I modded some bioses with custom voltages

http://forum.notebookreview.com/del...modded-bioses-download-gpu-voltages-more.html

just go to the previus link and pick the desired one. (only if you have a l502x!)

 

I have a Samsung rc530 so that won't help =(

So to be clear my gt540m doesn't go to P0 voltage level it only jumps from 0.83 to 0.85v

 

Hi everyone.
I've read through this thread from page one. I think that it wil be very helpful for me as I attempt to overclock my Asus U46. Thanks for all of the great info. I'm not really sure if I will be able to get some of the stable clocks that many of you obtained though the U46 is pretty thin and that effects the cooling potential quite a bit...but I will try it in small intervals and see what happens (and post it of course). Thanks to all.

So I know its been awhile since ive been here but im back and just wanted to let everyone know I successfully made a overvolted bios for the 3830tg because no one made or had one and I decided to finally figure out how to make my own, I started with an already modded 1.10 and give credit to him (forgot the name of the guy who made it, sorry dood) and im at a stable core clock of 872 MHz, now im pretty sure I hold the world record lol voltage is at 1v and actually temps barely increased, like maybe a few C, everyone knows I have one of the coolest running 3830tg's but this overvolt didn't do much surprisingly but aloud me to hit another 30 MHz or so and now I have an overclock of 200 MHz on the 540m.

 

And I just tried 3dmark06, I broke the 11k mark!!! NVIDIA GeForce GT 540M video card benchmark result - Intel Core i5-2430M Processor,Acer JM30_HR score: 11008 3DMarks

Edit: Did another run and got 11028!!

 

Playing Medal Of Honor Warfighter. All same setting, 1280x720 resolution & V-Sync ON. On Medium Setting I got 30-47 fps (Using this). 45-60 fps on Low Setting. 27-31 fps on High Setting. 20-23 fps on Ultra Setting. Battlefield 3/Crysis 2/Call of Duty Modern Warfare 3/Max Payne 3/Borderlands 2/Dishonored/Alan Wake/Batman Arkham City/Prototype 2/DiRT3 all tested overclocked with 800/1000 setting. Perfectly stable.

Here's my spec.

Acer Aspire V3-471G
Core i5 2450M 2.5GHz, 3M L3 Cache
Nvidia GeForce GT 630M (Renamed GT 540M)
6GB RAM, Windows 7 Ultimate 64-Bit
296.10 NVDIA Driver
GPU Overclocked to 800/1000 (Stable for all latest games)
50c min - 75c max (GPU) temperature while playing for hours.

 

Hi everyone,

Spent quite a while reading through almost every post in this thread before deciding to OC my GT540M (1 GB) too, but came across a problem – I set it to 800/1020 in MSI, all looks good. My frames in LotRO go from 36-37 to 42-45, perfectly stable, temps around 71°C max .

But in Battlefield 3, my frames go from 25-32 to 48-56. That would be great, except after a few minutes, the game goes black and I have to end task. My GPU temp never goes above 74°C. I notice in MSI it shows the GPU usage shoots up to 99% moments before it crashes.

I'm aware that I should just tune it down a bit until this stops occuring, but I was just wondering if it is normal to get such a significant improvement in performance in BF3 (I didn't expect to gain 20 FPS from this tweak) from this seemingly 'average' OC.

EDIT: I turned it down to 785/960, seems perfectly stable now, and I get 44+ FPS most of the time, spends quite a lot of time at 59 FPS (I set it to cap at that). This is entirely unexpected but most definitely welcome

Would really appreciate some experienced input, thank you in advance!

Other system specs:

Win 7 64 bit
i7-2630 QM
6 GB RAM

 

785/960 are some nice values you have there

Generally speaking, overclocking the GPU RAM has a negligible effect on performance and only increases heat unnecessarily. I only have mine at set at 926MHz, and the 1020 you had before is quite high.

I suspect your earlier crashes where caused by this (but ramping down the GPU core clock might have also helped! - There's a lot of trial and error in overclocking!)

TBH, 785/960 is a good overclock, and if you want more, focus on increasing core clock by about 5MHz and test it for at least a few gaming runs to make sure it's stable. You might also want to invest in repasting the GPU/CPU to bring down temps if your comfortable in opening up your laptop; done properly they could bring them down about 3-5C.

Cheers

 

so for some reason, I went 825/960 and it works, no crashes... temperature sat at a steady 68°C, too, funnily, because when I was running 785/960 it was up to 74-75°C.

Though, something that annoys me, and I don't know if overclocking is the cause, because it's been happening for as long as I've had the computer, whenever I'm playing any hardware-intensive games, if for example my settings allow me a steady 35 fps, for the most part it stays at or around 35 during gameplay, but occasionally (anywhere between every 10 seconds to every minute or so), the fps will stutter down to about 10-15 for a second or two before returning to normal.

It's something that has been bothering me for the longest time (also happened on my old laptop), and I have never been able to pin it down and I would be more grateful than words would ever be able to say if someone were able to help me solve it.

EDIT: And no, I am no where near comfortable to open up my laptop (the furthest I go is the RAM )

Thanks!

EDIT 2: Got a screenshot of the weird FPS thing I am experiencing illustrated on MSI Afterburner.

 

You didn't get your GPU usage at the same time.. thats what we need to know to go from there.

 

Hi,
I dont know how you did too high clock
I´ve got acer aspire 5755g, i5 2430m, gt540m 2gb , it´s true cooling is very low, before OC i´ve got CPU 94°C, GPU 96°C after OC to 810/940 i´ve got the same temperature, and when i playing NFS MW 2012 it´s stable like before +15FPS, but when i OC a little more it crashed and GPU reset after 2minutes of playing. Dont know how increase cooling system. Dissassembly cooling and new cooling paste?

mulzoff: how you did this GT 540m @875/1080 @1.01v ??? Any modded bios or only some utillities? And how about temperature ?

 

I've done some extreme mods to my computer to decrease temps, but you can do that definitely and it will help a lot. the 1.01v overvolt is new as my last post was at 1v. My bios is modded and I really haven't done any temp tests lately.

 

Apologies for the newbie error

Here is a screenshot I got today after playing LotRO for a few hours



I know it doesn't look like much but I cleared MSI's history after playing for a couple hours, and I let it collect data while in game I sat in a spot looking at an almost static scenery (just occasional person running past the screen or NPCs walking around). In game it was usually staying at around 35-39 FPS, then it would drop to 18-21 (sometimes down to 10 or below 10) before returning to 35-39.

Thanks!

EDIT: I'm also using the 306.97 drivers at the moment, if that contributes any. I have been using 296.10 drivers for the longest time (I've found them to be the most stable and best performing for the games I play – but this annoyance has been occuring regardless of the drivers I have used, from 285.xx to 3xx.xx), but very recently updated to 306.97 while trying to get Planetside 2 to run better (hasn't made a difference there).

 

mulfz.. did you use some utillities only ? or some modded bios ?

 

Interesting problem there...

That is generally characteristic of throttling, but 70C should still have plenty of headroom

Does it correlate with CPU usage increase in-game?
Is your adapter providing sufficient power? (What's its rated wattage?) - If it's about 90W then that could possibly be the cause
Set the powerplan to high performance if you haven't already.
Try running Furmark GPU Stress Test and see if the same thing happens.
Also try doing a clean reinstall of the Intel and Nvidia drivers (perform a clean install when prompted for Nvidia)

Hope it works out!

 

Haha no problem man!
Hmm, it cant be power supply if its a 90w Matrix5 because im running a 90w and I have my GPU at 875 with 1.01v and it supplies enough power. It could be the games programming, some power saver bull from Dell, or drivers. It looks like the game though because you dont max out your GPU usage, can you screenshot some other games?

LukysCZ, I did it myself originally with extracting my vbios from my bios, modding it, then putting it back in and flashing it. When I did 1.01v, I had help from Nedemai because you can't go further then 1v without hex editing and I'm horrible at hex, so he helped me with the hex part and I flashed it for testing, but we worked on a few different overvolts and learned that anything over 1.02v on my laptop my VRMs cant handle it and wont/cant supply the power.

Also you've all been wondering about my temps, I do have a 3830tg, but after a run of 3DMark06 at locked 2.8/3.0 GHz on a cooler, I got max 69C GPU and 77 CPU.

 

Thats nice temperature. When i´m playing games i can cook next to the cooling

 

I need to repaste too, its been almost a year now.

 

Yeah I always do a clean install of drivers and the first thing I do after every update is set/ensure everything is set for performance

The earlier post I made showing the FPS graph without the GPU usage was in BF3 (and LotRO and BF3 are really the only 2 games I play atm). That one in BF3 is really annoying me, because it seems to drop off at very consistent intervals (that graph vs the 2nd one I posted). Also though it's cut off from the picture, the indicated GPU usage % increases and decreases almost perfectly in time with the FPS, but never comes close to 100%.

It happens regardless of what's happening on screen, whether I'm standing still, or running through places with lots of explosions and particle effects and screen blur, or crawling around the ground, perfectly illustrating the issue I'm having.

It seems (to my uninformed mind) more of a software issue than hardware which sounds like just poor optimization or something that should otherwise be fixable without having to pry open my laptop (which I really don't wanna do).

EDIT: Slightly off-topic, but I also notice my video memory usage usually only stays around 300-320 MB, would I be right to assume that this means I can afford to raise the texture resolution in games? If I understand correctly, the only downside to raising the texture res is that it uses more video RAM? Or is it good to set aside a chunk of vram for other processes? Thanks!

 

Hmm.. it could be your computer somewhere then from dell, check your power supply, tell me its voltage and amperage and we can go from there.

About your VRAM, 2 things, Our GPU cores aren't really fast enough to have high res textures and anti-aliasing on most games, so we only use a bit of our 1/2GB of VRAM, we would be find with 512, which I would actually perfer as they OC better but anyways to your answer, only if your GPU core isnt being used to the point where your getting horrible FPS, then you can turn up the settings which makes more GPU and VRAM load.

 

EDIT: Oh by the way I'm not on a Dell, I'm actually using an Acer Aspire 4750G (I think), just came across this thread when I Googled for "GT 540 M overclock"

 

You guy's can reduce your temps a lot by pulling the blue pin on the fan connector forcing the fan to 100%. On my K53SV I cut a hole under the laptop with a soldering iron to allow the fan to suck in cool fresh air when the fan is at 4,700rpm. Under the keyboard is an air intake vent. Remove all the plastic covering the 50% left side of the keyboard allowing the fan to suck in even more cool air from under the keyboard. Get some rubber mounts from your hardware store with sticky material and attach 2 to each side of the battery and 2 towards the front of the laptop on the left and right side. These rubber mounts will give you 0.5" of additional height so the fan can suck freely on any surface. My idle temps on my GT540M and my Upgraded 2720QM are around 35C and if I put a shim on my gpu I get stability at 800Mhz hitting just 55C under load. Without the shim my temps hit 60C and it is not stable, I get display driver failures. It's important to make sure the cpu and gpu heatsink base is 100% perfectly flat on the chips from very thin layer of thermal paste on each chip. Under ideal conditions I was able to run at full 3Ghz turbo boost and 800Mhz and the CPU hit 75C and the GPU hit 65C. Right now I'm looking into finding a copper shim for the core i7's 216 mm2 die size which is almost impossible.

Any luck on voltage adjustment for the ASUS K53SV? EVGA EVTUNE allows the changes but won't apply the voltage changes.

 

Is there any link for download GT540M 2gb VBIOS ? Original or some with modded voltage

 

attached the ones from the L502X

this package include the original 540m bios

and a modded one with 0.83v/0.85

 

Can i flash it into Acer aspire 5755g with gt540m 2gb or i must have VBIOS for gt540m exactly for my laptop ?

 

I´m thinking about this:
GT540m bios mod for L502X DOWNLOAD from mediafire /// MIRROR by ximinez
MD5 checksum: B88FB590733179CA5E3BE1253EEDBA86
BIOS version used: A11
this bios mod has been tested by jingtai1993
2D PROFILE: 0.85v
3D PROFILE: 1V
notes: Overvolted A11 BIOS version for gt540m , should be nice for OC , the 2D voltage is also tweaked, may fix GPU crashes while exit from game to desktop (fast voltage switches), beware the extra heat!

What do U think ?

 

It should work, but it may have specific hardware stuff.

I would mod directly the one from your laptop, it will have 100% chances to work

edit: well, setting voltage isnt hard, you can do it even without hex editor, nbitor do all the stuff when you open the vbios with it.

the headache comes while extracting and reasembling the vbios at the main BIOS ^^

 

I would by glad, If U can do this for me, because i cant find files for my laptop and i´m not too skilled.
My laptop Acer Aspire 5755g GT540M 2gb DD3, i5 2430m, Win 8 PRO+Media center

 

if you can provide the bios file from the latest laptop update from the laptop update site I can give it a look.

I need some kind of file like a .bin .rom, .fd .wth extendions

just let me to know what voltages you want, there are also even slim chances I find locked menus if your BIOS type is like the ones I unlocked

 

Dont know what update U mean. Voltage 2D should me orignal and 3D 1V if its posible. i´m using unlocked BIOS V1.20

 

Unlocked bios H20 rev 3.5
But i think U can use acer original bios v1.21 because i dont need unlocked features.

a link to the modded bios topic or modded bios file will be apreciated

 

How i said a reply above. U can use original acer 1.21 http://global-download.acer.com/GDFiles/BIOS/BIOS/BIOS_Acer_1.21_A_A.zip?acerid=634883809430577449&Step1=Notebook,%20Ultrabook&Step2=Aspire&Step3=Aspire%205755G&OS=8u1&LC=cs&BC=Acer&SC=EMEA_7

If its possible to do it with original BIOS

 

oh, didnt saw you edited the post


ok, got your BIOS


can you take a pic from the main screen of gpu-z ?

you can download it from here.

Download TechPowerUp GPU-Z v0.6.7 | techPowerUp


I need it because I noticed there are many different video bioses at your bios

there are 4, 2 from 540m, and other two from another card.

for the gt540m there are two versions

70.08.3C.00.19

and

70.08.3C.00.22


I would like to know wich one you are using, so I can mod the correct one

 

Ok, here is it


Uploaded with ImageShack.us

 

@LukysCZ

try this one.

I modded it to 1 volt like u said.

u need to flash from DOS

modded.rar

 

I´ll try it and write how it works

 

mmm, I dont know, never dumped a nvidia bios from dos, I just dumped AGP ati cards from dos.

all nvidia bioses I got were from laptop, and I extracted them from BIOS.

if u want to flash the bios I made for you, copy all the files from the package to th root of your dos bootable usb stick, reboot the computer and boot os, then type BIOS and there you go

 

allready done it, only create bootable USB DOS and copy your files on it and type i DOS mode "dir" and than BIOS.exe and it flash bios succesfull
