Overclocking the GT 555M card.:-)

Anyone update to R300 drivers yet? I tried yesterday but ended up rolling back since it gave me the BlueS of Death at random intervals. Plus they downclock my 555 AFTER stress tests, never during but AFTER. Is that thermal throttling or a driver crash? Bad install? or is it the drivers?

 

Hi everyone,

I am using the volt mod BIOS as linked by letmeknov. Till recently I was using MSI Afterburner to overclock my Dell XPS L702X, but I noticed that the core clock fluctuates while playing games depending on the stress the game puts on the card, such as transitioning from game action to video cutscenes. Afterburner doesn't allow overclocking past 770 so I am using 760/1520/1000 (C/S/M).

So now, I wanted to get rid of this annoying downclocking that occurs even when gaming in 3D profile. I tried Nvidia Inspector and there was an instant gain of 16 fps in the game at same clocks. Unfortunately the computer goes "Brrrrrrr" and shuts down (abruptly) within 1 minute of gameplay. Never did this happen with Afterburner. I went on and tried EVGA Precision, which has a better GUI (similar to Afterburner) and face the same issue of the computer shutting down.

While I am loving the huge FPS gain, I can't understand why the computer shuts down again and again. I can only imagine its a safety cut off of some sort. But everybody else can use these software, then why can't I? If I can make the card run at the same clocks then I could perhaps push it further.

Anybody experienced anything of this sort? Blackscreens, etc?

Cheers!

 

mean_tee82, Is it happening with all of your games or just one? What are the gpu/cpu temps while playing games? Also I strongly suggest you to check your gpu for artifacts with 'EVGA OC Scanner X'. The thing is, that every gpu has it's own overclocking flexibility, even if they came from one factory at one day. It's like a lottery and you never know.

 

Thanks for replying. It happens with all games. Its summer here so the temps are a bit high anyways and I don't think its temp related as the computer crashes even if the game was just started and the temps are not that high.

Yesterday, I reset the clocks to the default speeds and only OC'd the Core clock using EVGA precision to 800 leaving the memory clock at the default 900. I believe the Shader clock is linked to the core and got OC'd automatically. I could play without any issues, no crashes.

I think this GPU can take a lot of stress, I have not seen any artifacts so far using this GPU, but I shall try the software you mentioned.

The thing that surprised me is that by using Afterburner for a year, I was missing out on this 16 FPS gain
I think its the higher memory clock that's causing the crashes. Any idea why?

Cheers!

 

Yes, it really could be. As I remember now there was some game crashes for me when I was trying to push up memory clock higher than 1000 MHz, so even an extra 10 MHz might crash the gpu driver. Try to pull down the memory clock below 1000 MHz and check if there's no more crashes. The overclocking potential of this gpu is more than great. Cheers.

 

Yeah I am at the default memory clock right now without any problems.
Some people are even able to OC the memory to the order of 2000MHz, I wonder how !!
I ran OC Scanner, no artifacts recorded. All in all, I am very pleased with this card compared to the HD4670 that came in the older XPS15.

 

i think i had my memory at about 1080-1100mhz if i remember correctly and it was very stable. Can vary a lot between each laptop though.

 

I can achieve those clocks using Afterburner, but not with any of the other OC'ing software. The moment I raise the memory clock it crashes.

 

Maybe a clean driver install? Does lowering your mem clock cause crashes aswell?

Enabling the screen saver also can cause BSODs for some reason.

 

hey guise!
me and my lovely l702x
i7 2760, 4 gigs 1333 and hd screen.

so i was testing on a fresh win7 isntall (home prem)

this is with the stock driver, from the website:


this is the newest driver:


like before, but double ram... 8GIGS


and with a slight overclock (760)


max temp with this overclocking was 77 celsius degrees, i was testing it with minecraft + glsl shaders (eats the shieet out of your computer)

id like to ask, what the hell is that proc performance jump on the second picture(1st vs. 2nd pic)? i did not do anything with it...

and here are some 3dmark11 results, first 590, the second with 760



im brand new here btw...

 

Probably had something in the background using up a bunch of CPU power for the first test. 31-32K is about right for CPU score.

 

Hey everyone, My mobo's northbridge died so I had to RMA. But after a week and a half..(there were complications) It's time overclock. (Am I right that the northbridge failing has nothing to do with a gpu only OC? Stock bios/cpu/everything else.)

So with a new mobo comes a new chip.
it's a gf116 ddr3 like the last
840 core / 1000 mem and hitting p1823 on 3dmark11
NVIDIA GeForce GT 555M video card benchmark result - Intel Core i3-2310M Processor,Micro-Star International Co., Ltd. MS-16G5 score: P1823 3DMarks

Currently folding to verify stability, but a few minutes of Heaven and it seemed to be okay with 3dmark. Will update as I progress.

 

God bless you folks.....was kind of disappointed with my xps 17 performance in skyrim. Googled improving performance of 555m and got this awesome thread. Read from page 1...great advice and i feel pretty comfortable with the information here.

I installed the MSI program and clocked it up to 770. Runs stable as hell and max temp after playin skyrim and SWTOR for hrs is 71c. Havent run any benchmarks but having it overclocked for the past week and having no problems im pretty stoked. at least 7-10 fps increase in SWTOR according to fraps and the roughly the same in skyrim.

Not only that but being able to plug in the hdmi cable and play on the 44 inch big screen in HD is sweet....couldnt really play at that rez before the overclock and now it runs butter smooth.

Just wanted to say thanks to all of you for the wonderful information and turning this already sweet laptop into a ! /cheers

 

Hello,

I just ran the benchmark test for DX11 (only benchmark test) and my computer seems to have gotten a pretty low score. I did not overclock yet and I was running on batteries. I will retry the test when I'm home, but until then, if anyone knows the reason, let me know. I am running the latest beta driver - 306.02

Benchmark result: NVIDIA GeForce GT 555M video card benchmark result - Intel Core i5-2430M Processor,LENOVO Base Board Product Name score: P876 3DMarks

Edit: I re-ran the test home and here are the results. NVIDIA GeForce GT 555M video card benchmark result - Intel Core i5-2430M Processor,LENOVO Base Board Product Name score: P1213 3DMarks

It however did not detect the "clocks" I set. My settings are 800MHz core clock, 1600MHz shader clock and 1000MHz memory clock. Anyone knows why it says 750 clock?

Also a question regarding memory clock - by default, it was set to 1420, should I change it back to that much? Is more better?

 

Can you please run and post a screen from GPU-Z?
GPU-Z Video card GPU Information Utility

You see there are multiple versions of the 555M, and their performance literally ranges between the 550M and the 560M

Anyway, yes, higher is better when it comes to overclocking as long as it's stable. BUT from you're post you don't sound to have much experience OCing so I suggest you do alot more research on how to safely OC before attempting anything or you could risk killing your laptop.

Basically you:
1) bump up clocks by 5hz
2) stress test for 5 mins using MSi Kombustor
3) repeat #1 until you see weird "artifacts on Kombustor" or the program crashes or your computer crashes. List down your clock settings when this happens
4) set your clocks to 10Hz below your findings in #3
5) stress test again with Unigine Heaven 3.0 (Kombustor will only fry your laptop if you do it for too long). Run unigine for at least an hour or more.)

Basically you do this for both core and memory clocks.

Here's what I got using a gf116 ddr3 gt555m
NVIDIA GeForce GT 555M video card benchmark result - Intel Core i3-2310M Processor,Micro-Star International Co., Ltd. MS-16G5 score: P1894 3DMarks
that's with 900 core / 900 mem

It's a good idea as well to note the wattage of your power brick/charger . I have an 80W charger and under load, charging the battery makes a difference between stable and unstable clocks

 

[Mod] Asus N55SF - voltage increase for Nvidia GT 555m

has anyone tried this voltage increase for Nvidia GT 555m? id like to try this mod but worry if i will face any over heating BSODs that were mentioned in the thread, is it a good idea to do this mod as im still on a older 204 version of the asus n55sf bios but would definitely like to improve my gpu performance

 

How are your temps at the moment? run unigine for an hour or furmark/kombustor for 15 mins. My MSi runs at the limit of it's power and thermal capacity when OCed, so much that I stopped running my vRAM overclock to achieve stability. Bumping clock rates generally increase heat linearily while bumping voltage increases heat quadratically. So I highly recommend avoiding volt mods unless you have the money to buy a replacement and your temps are well below 80 C under full load.

I have to stress too that the output of your laptop charger can affect your OC stability. During stress testing if you see your large fps drops at seemingly random times, then you could be lacking power from your charger. Try disabling all unused peripherals or dial down your OC to get it stable.

 

Well I did install the msi afterburner app just not sure what settings I should put it at for my gt 555m card my CPU is a i7 2670QM @ 2.20GHz

Every card has different limits to how high it can OC, that's why I said above that you need to slowly bump up the clocks and test each time. You seem to have the same version as mine so I'd try starting with 750 for core and 950 for mem then work your way up using the method I posted above (or from any other OC guide).

The N55 also uses a 90W charger like mine, and in my experience at above 800 core/1000 mem everything plugged in to your laptop (that includes the battery, network adapters, webcams, bluetooth, cooling pads) WILL affect stability. At clocks above that you'll be forced to remove/disable parts you aren't using to get the OC stable.

edit: I used nVidiaInspector to overclock to 900 core since afterburner maxes out at 845 core

edit: what voltage does your card use under load?

 

Hello all, i got this problem with BF3 after overclocking my GPU. It starts, when i set the graphic clock over 665, then a got this CPU and GPU throttling, though the temperatures are GPU 76 and CPU 91 max. And this is only in BF3, in other games the problem does not exist.

 

It's probabbly the CPU throttling, I've run my GT 555M at 90 C nonstop when playing DiRT 3. If I remember correctly i5/i7 cores throttle at 90 C so that's probably your problem. Try looking for ThrottleStop or download BF3 settings editor and look for framerate limit and set it to 60fps

 

Hey,

I tried to OC my GT555m (3GB version) on my XPS 17 yesterday, with i7-2670QM, if it helps, yesterday, as I felt my Dead Space 3 performance wasnt as good as I was expecting, at least compared to Dead Space 2, where I got decent fps on medium/high settings, while on Dead Space 3, its only really playable on low settings, where its usually a constant 30fps, then decreases to around 18+ fps where "real gameplay" starts.
I tried to OC my graphics card using both MSI Afterburning + nVidia's performance tools, and according to GPU-Z, my new clock values are registered, but I have noticed no difference in fps on Dead space 3 or GTA IV, where on GTA IV at least in the same area, it was always at around 28fps+

I increased clocks from:

Core clock: 590 -> 700MHz
Memory Clock: 900 -> 1000MHz

So it feels like nothing is actually going up to the new values.
I would like to overclock without changing the voltage if possible though.

Thanks

 

Your memory clock is ok, but you can try to push a little bit further your core clock. I am using 770 for core, 1000 for memory, and the average fps gain is about 10-12 frames. So my suggestion is to leave the memory at 1000 (anyways it doesn't affect much performance like core clock, but generates more heat) and try to push up your core step by step to see it's potential. Every mobile gpu (even same models) has their own overclocking limits.

Good luck!

 

Actually, I tried it too and same result as the guy you responded to.

I get no performance boosts (no matter what setting) and I can't underclock either. GPU-Z tells me the clocks did apply.

I have the 3GB version, running Windows 7 64-bit.
Driver version is 314.07.

Weird thing is, it did work the first day I installed it. The day after it just stopped working...
I've tried reinstalling MSI Afterburner, with restart after uninstalling without success.

 

Maybe be it's a Afterburner's bug, don't you think so? I used Afterburner for quite a long time, but now I switched to Nvidia Inspector, it's very light and handy Try it and see if it works.

 

Hi,
I own an Asus N55SF with a 555M GT.
I've been trying to OC the card but I keep getting BSoD's.
With a 740/1480/945 OC or even 720/1440/930 I get a dump caused by nvkflt.sys, dxgkrnl.sys, dxgmms1.sys.
I have the latest drivers and I preformed a clean install with DriverSweeper.
GPU temp is around 85C, CPU (i7 2670QM) is around 95-98C, BD PROCHOT is off.
The crashes seem to happen randomly - after about half an hour of gameplay and sometime only after two or more hours.
Any ideas...?

 

Your temps are quite high. Both GPU and CPU. I don't remember mine exactly, but even after overclocking my GPU never goes over 75C. Maybe there's some dust buildup in the heatsink, I would try cleaning that up. Also when I overclock GPU I only overclock the core, memory doesn't give it much boost anyway, and there are artifacts and driver crashes when I overclock the memory. Most performance gain afaik comes from overclocking the core.

 

I already opened and cleaned the heatsink. Before that the CPU was throttling down to 1.3 Ghz because of the heat, now it is stable at 2.3 Ghz and the temp is around 95-98 (on load).
85 for a GPU is ok i think, I had worse. I Kept logs of both CPU and GPU and they were at 97C and 85C accordingly at the moment of the crash.
But still, the BSoD is caused by the driver file and what appears to be a directx files...

 

Does the same happens if you only overclock the core?

 

Just tried it and yes, after an hour of gaming i got another BSoD... CPU was at 98C and GPU at 86C during crash

 

well i clock my gt555m to 590/900 > 810/1000 improved a lil bit but not much
sofar i havnt gotten a bsod, only if i clock memory higher

sadly there havnt been any neww bioses arround not even vbios

 

I wouldn't go higher than 750Mhz Core because it will generate more heat for very minimal FPS since CPU and GPU sharing same one heat sink!!!

 

I think it's your CPU. CPUs should be kept below 90C since that's the safetylimit for i5/i7s. Going at 98C is probably killing your CPU thus the BSODs. The GT 555M starts throttling at 93 C. If your cooling system has seperate pipes for CPU and GPU, then a GPU OC won't affect the CPU too badly. Try to have someone/or learn to repaste both CPU GPUs there are plenty of tutorials out there and would do wonders to lower your temps. A temporary measure is to go into your power settings and set your CPU max load to be at 60-80% as that should give you enough grunt for gaming without as much heat on the CPU.

I also use nVidia Inspector for overclocking as it is more stable compared to Afterburner. I run Afterburner + HWinfo for temperature and framerate monitoring.
So far I've OCed to 900 core, 900 mem(ddr3) though I'm currently limited by my 90W AC adapter :/. I'm thinking of picking up a 120W adapter though, since I know that I can push my memory clocks to 1000 if I keep the core at stock. After that maybe drill out some extra venting so my cooling pad gets to blow directly at the heatsink.

 

Ok after few months of playin arround with MSI and nVidia System Tools i left MSI and just use Sys Tools and the only settings i found usefull is
709x900 System ratings jumped from 6.9 to 7.1 and if i try anything higher games cramp up...these are stable at 71-75 degrees even with NFS Most Wanted ,,,,and these are the only setings that run Borderlands 2 on 1920x1080 on full settings except PhysX witch is still on low

Hi all.

I am new at overclocking matters, so I want to overclock my 1GB GT 555m to play FIFA 15 with better quality.

I have Lenovo AIO B520 (i3 2120 3.3GHz, 4GB ram plan upgrading to 8GB), when i tried to do it myself i found different values than any previous posts. so i got lost.

Anyway, if anyone can help me , i will be very appreciated, there is a screen shot with my default values and GPU information.

Thank you.
