I recently bought a laptop and before it ships I have been looking around at how the 8400m GS performs. The video card is labeled at 128 mb but many people have been posting on forums about how they're cards are telling them they have 256mb instead of 128.
More commonly, Youtube videos are all titled 8400m GS *256*. Is the 128mb version just really uncommon? Or is it really 256 mb. I also stumbled upon something called Turbo Cache (not sure if that's the right name for it) that has the GPU use some of my systems RAM...Isn't that what integrated chipsets do?
How crappy is the NVIDIA® GeForce™ 8400M GS really? I am using a 7800gtx in my inspron 9300. Just ordered a 1330--- is the 8400 superior to the 7800gtx?
on a related note, is there anyway to upgrade the NVIDIA® GeForce™ 8400M GS to a different video card? Is any other nvidia card compatible?
Dell XPS M1330 - nVidia GeForce 8400M GS - Copper Mod - Step by Step Guide
Dell XPS M1330 Notebook with nVidia GeForce 8400M GS GPU has an inadequate Thermal Cooling Assembly. It uses a Thermal Cooling Pad between the GPU and the GPU Thermal Cooling Assembly instead of a direct contact between the two with a Thermal Compound. This leads to overheating the GPU and damaging it along with other components. The solution is to replace the existing Thermal Cooling Pad with a Copper Sheet and a Thermal Compound.
Note: This Copper Mod does not solve problems arising from a weak die/packaging material set in certain versions of GPU. Their failure appears related to the combination of the interaction between the chip material set and the system design. The combination of limited thermal management and frequent power cycling is particularly challenging for the GPU. Dell is offering a 12 Month Limited Warranty Enhancement specific to this issue. However, this Copper Mod might help delay the failure by improving the thermal management.
I had assumed, but I want to make sure that my SZ6's problem is due to the Nvidia temp defect thing everyone's talking about.
Basically my computer is always very hot. Just downloaded SpeedFan and the GPU and both Cores are 78C and i've just been surfing the web for a few hours.
The problem happens when I play games (like Civ4 or Half-life 2) for a few hours or sometimes less if its a hot day. The laptop will abruptly power off as if I pulled the battery and power cord out.
When I reboot, I get that error message that says Windows did not shut down properly, do you want to reboot normally or in safe mode
I only get 16bit color in xp but in vista there is no problem I have 32 bit. When I change resolution to 32 in xp on next boot it rechanges itself to 16 again.! I have all fn keys working and power management and this is only issue I have with xp
I have a Sony VGN-FZ38M (originnaly bought with vista) and I have installed windows 7 64bits
My graphics card is a NVIDIA 8400M GT, and I've tested a lot of drivers for this model but no one works. tried both drivers on sony [url] webiste but always same issue : "your system is not supported..."
i have HP DV 2700 with nvidia 8400m gs. the laptop has 2 graphics chips intel gm965 chipset with gma3100 and 8400m gs. is it possible to switch between the two. i am having problems with drivers. i am not able to install latest drivers from nvidia site. it doesnt show on rivatuner saying nvidia driver not detected. the driver from hp works but its very old 176.xx. so is there a way out to install new driver and switch between graphics. i searched intel site but did nt find any thing related to this problem.The bios doesnt have any option like the desktop pc s have. Does bios tweaking...
I have a Sony Vaio VGN-SZ780 that passed its 1 year warranty a few months ago.
My laptop was experiencing overheating and would either reboot suddenly after the blue screen of death or would just shut down in the middle when using the nvidia 8400 GPU.
From Sony's explanation, I read that the shutdown of the system is a normal behavior under high temperature and I assumed it was not a problem and just an inconvenience.
Just 30 minutes ago, my laptop screen turn white completely and froze so I shut down the system immediately and since then, my SZ780 DOES NOT BOOT when using the Nvidia GPU!
Sony's recent replacement annoucement of defective Nvidia GPUs EXCLUDE the SZ models so for me, I have no additional warranty that can cover this.
This has been getting on my nerves lately. In the past, they never bothered releasing drivers for laptops but now that they do, I can't get it to work with my laptop, which is HP Pavilion 6670ee with NVidia 8400M GS...
I know that 3rd party driver will work with it but I am not able to get the PhysX support with those drivers for some reason and if I download Notebook driver from NVidia website, the latest which they released few days ago for example.
I get this error during installation:
The NVIDIA setup program could not locate any drivers that are compatible with your current hardware. Setup will now exit.
It's NVidia's own 8400M GS - wth is it not detecting it?
Can anyone be kind enough to share a flash ROM copy of Nvidia Geforce 8400M GT notebook graphics display for
Sony Vaio VGN-AR61M? A backup copy done with Nvflash, NiBiTor or any similar flash app perhaps will do.
I need to flash my video graphics display which is no longer recognized. For some unknown reasons,
after installing and playing some high resolution games, my pc crashed and suddenly Windows 7 display won't accept any video driver except the standard VGA adapter
I recently got a Dell Precision M4300 from a friend and had a few questions.
When i got the laptop, I reformatted the Laptop and Reinstalled Windows XP Pro SP2. I proceeded from Microsoft to Update to SP3 and so on.
Well I also Went to Dell's Website and downloaded all the necessary drivers (using the service tag) for this laptop and installed them.
Now here is where I ran into a problem,
When I installed the NVIDIA drivers for the NVidia Quadro FX 360M video card, everything seemed to go fine. Then I rebooted the Laptop, and now every time I reboot, my hardware acceleration is defaulted back to None, and it gives me multiple pop ups about this issue. I go into the settings and turn the Acceleration back to full and it goes away.
This is a major problem, and is really frustrating to deal with everytime the laptop is booted up.
My other problem, is when I open up Internet Explorer, It tends to lock up the browser for no reason when Loading a website. I then CTRL+ALT+DEL and attempt to close iexplore.exe via the task manager. It closes the browser but does not shut down the browser, making it impossible to browse, so then I have to reboot.
here are the specs of the PC, from the device manager and drivers I have gotten
Dell Precision M4300 NVidia Quadro FX 360M 512mb Video Graphics Card TSST 8x dvd+-R burner 120GB Hard Drive 3.5GB of Ram 2.5GHZ T9300 Core 2 Duo Processor 1394 Port 2 USB ports External Monitor Ports Wifi Support Bluetooth Support Windows XP SP2 Pro
I refreshed my colour settings under 'nVidia control panel' and now my colours look crap. Can someone plz give me your personal prefered percentage numbers of these following slide bars in 'Desktop Colour Settings'.
i have a dell inspiron 1720 with a GeForce 8400M GS 128 ya i know it sucks but anyways when i go to dell or do a google all im seen is that the 8400 is a 256 ddr is this right? i run a program called TechPowerUp GPU and its saying 128 to did they make a 128 and a 256?
I own a vostro1510 with a 8400m gs. i am a casual gamer and during gaming gpu goes upto 85c. i am worried about my gpu as we all know about the failure rate of 8400 and 8600. my warranty is going to expire on sep 15 so do you guys recommend me going for extended warranty? i find it a bit costly.
remember my laptop was purchased on sep 15 2008 and my mobo was replaced few months back(not due to failing gpu). someone also told me that the replacement gpu's are not defective is it so?
Currently my M1530 has the nvidia 8400M GS chip in it. I'm thinking about swapping the motherboard out for one with an 8600M chip on it.
My question is, will it make much of a difference? How much greater is the 8600M w/ 256mb versus the 8400M w/ 128mb that is currently in my machine? Look forward to your responses.
So I have a broken Nvidia Geforce 8400m GS GPU on my Vostro 1400 out-of-warranty (even with Nvidia extension) laptop and Dell wants $240 to repair it.
That money could probably go to a new laptop, but I was still wondering if there was a way I could go for a do-it-yourself repair. How would I go about replacing the GPU? Is there a guide for this somewhere I could look for?
I'm guessing I will need to order a replacement motherboard from Dell to do this, but I'd rather attempt repairing the laptop on my own rather than send it to Dell's out-of-warranty repair depot. I've taken apart PCs before, but have never taken apart a laptop.
I contacted the Dell support team to see whether my m1330 is affected by the bad batch of Nvidia Graphic card and I got this respond
-----------------------------
On your concern about the Nvidia Graphics, I should say that your system is not affected by it, however I am a Hardware expert with the XPS Team and would recommend to diagnose the Hardware to identify any problems.
To extensively diagnose the 'Hardware', your active participation is requested. Please follow all these steps mentioned below as they are inter related:
1. Disconnect all the devices which are connected to the system, like:internet cable,usb key,etc.
2. Power off the laptop. Disconnect the power cable from the laptop.
3. Close the system, turn it upside down, slide the battery latch and remove the battery.
4. Keep the battery out and put the system back in front of you..................
I just stumbled accross the thread about modding some dell with an 8400M GS vidcard, I was wondering if this also applied to sony as well.. or they did a good job adding thermal compoung to the heatsink.
I just wanted to know if any of you did some mod, if it's really necessary or my GPU will melt slowly while I game.
Some guy said about placing a copper sheet in between the heatsink and the gpu.. but I still don't get how much pressure should be applied when bolting the screws.
On the other hand has anyone mod their 8400 M GT to say a 8600 using rivatuner..
I just discovered an interesting issue after undervolting my DV9700's CPU and overclocking its graphics chip but forgot to post it earlier. When playing GTAIV (which is extremely GPU intensive as you know), the whole notebook will get warm. I already know from FurMark that my 8400M GS will reach 80C in its current configuration so i can understand why the thing gets warm. However the fan always runs at minimum speed when playing GTAIV...
This leads me to believe that the cooling fan is exclusively controlled by the CPU temperature. It wouldn't matter if the graphics chip would be on fire - the fan will still not ramp up unless the CPU reaches the temperature threshold. I'll check exactly what these threshold values are later, but i remember that on my DV5 it's 75C for high and 85C for maximum. The fans on these things have 4 speeds IIRC.
Now, my DV9700 is a large and rather solidly built machine. It easily copes with the heat even with the fan turned down, i have no issues with GTAIV or any other game, and if you recall it had a faulty fan when i got it yet it was still able to work for 20 minutes before reaching shutdown temperature.
But if this is true for all laptops, i can see why these GPUs fail. Notebook manufacturers should consider implementing a fan controller that reads from both CPU and GPU sensors.
I have been reading the threads related to HP notebooks with defective nVidia GPUs and just out of curiosity, I checked the 8400M GS GPU in my roommate's HP dv2700 notebook, which normally runs @ 80 - 90 deg C, using GPU-z software. The sensor data matched the default core / memory clock for 8400M GS, when under stress. But I got confused when I saw that the shader tab is disabled .
I do not know if somebody else has already come across this situation. I searched here and could not find a similar reported problem, hence this thread. Am I missing something here or is there someone out there having the same problem. Can it be something related to an older ForceWare version (156.65)?
