Dell :: NVIDIA® GeForce 8400M GS

Jul 19, 2007

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 :: Replacing Geforce 8400m GS GPU On A Vostro 1400?

Feb 22, 2010

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.

Dell :: XPS M1330 NVidia GeForce 8400M GSCopper Mod

Jul 2, 2008

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.


01. Copper Sheet. Recommended: Gauge 16 & Grade C106 - 14x14x1.5mm.
02. Thermal Compound. Recommended: Arctic Silver 5.
03. Thermal Compound Cleaner (Isopropyl Alcohol or Acetone).
04. Cotton Swabs.
05. Paper Napkins.


01. Phillips Screwdriver - #0.
02. Utility Knife.
03. Thermal Compound Spreader.

Drivers & Utilities: (for Microsoft Windows Vista 32 Bit)

01. Dell XPS M1330 A13 - 1.02MB. (BIOS Firmware). Recommended.
02. Dell nVidia GeForce 8400M GS 176.44 A10 - 52.70MB. (Video Driver). Recommended.
03. HWMonitor 1.11 - 397.00KB. (Monitor GPU, CPU, Chipset and HDD Temperatures).
04. GPU-Z 0.2.8 - 410.00KB. (Monitor GPU Clocks).
05. I8kfanGUI 3.1 - 1.61MB. (Monitor Fan Status and Speed).
06. RivaTuner 2.11 - 2.30MB. (Monitor GPU Status on OSD).
07. 3DMark06 Basic Edition 1.1.0 - 413.00MB. (Benchmark GPU).
08. Intel Thermal Analysis Tool 2.05 - 3.31MB. (Benchmark CPU).


Before You Begin!

01. Disassemble the Module Cover by loosening the four Screws.

I have a Acer Aspire 5720G, with a Geforce 8400M GS graphics card apparently, i have every other driver installed for xp. The only one i cant seem to get to work is the graphics driver. I have tried Google and downloaded numerous drivers but i cant seem to find one that will work, they all either wont install because they don't recognize the hardware, or with custom inf's from laptopvideo2go they install then when i boot windows, then say they're incompatible and have reverted back to the default VGA drivers.

Sony :: Vaio VGN-FZ18M Driver For Geforce 8400M GT Is Not Compatible

Dec 30, 2009

I have a Sony Vaio VGN-FZ18M Laptop (Running Vista Home Premium) which I would like to update to Windows 7 Ultimate.

On running MS compatibility Checker it points out that the Driver for Geforce 8400M GT is not compatible.

When I try to find a new driver via NVIDIA I keep being referred to Sony who seem to have washed their hands of the problem See reply message below.

Can you point me at a driver that will work with Windows 7 or has anyone updated to Windows 7 with this Geforce 8400M GT driver and had any success.

I seem to be going round in circles trying to find a solution.

i.e. NVIDIA say go to Sony and SONY say go to NVIDIA

I note from searching the net that there are many people out there with Vaio FZ models having similar problems and that Sony seem to have created upgrades for quiet a number of their models but have stated “Please note that your computer is not eligible for the Upgrade to Windows 7.”

This I find disgraceful for a Company to completely wash its hands of supporting a machine that is barely 2 years old and the fact the New OS from MS is seen as an industry standard which they will be delivering in future. They refer to it as 3rd Party Software which their reply would infer they are not going to support in their machines. I wonder if that applies to their latest models?

Dell :: 8400M GS Dying

Dec 7, 2008

Is my 8400M GS dying?

The other day I started to have intermittent 'display driver has stopped responding and has resumed' messages after the display blanks for a bit.

I checked my performance. In RTHDRIBL where I used to get high 40's to low 50's fps, I now get in the 20's, 30's, and 40's.

Then I checked some of the games (which I haven't played in a long while). Colin Mcrae Rally 5.0 and UT 2004 are so stuttery that they are unplayable.

I tried various driver versions thinking that the latest driver version from windows update was causing it, but have not had any success.

I also uninstalled Avast anti-virus and Rivatuner in case bad settings were the cause.

WEI score used to be 4.1/4.7, and is now 3.7/4.5

Dell :: 8400m Gs Overclock

Jan 26, 2009

don't do this, unless you have the copper mod.

But I overclocked from 400/600 to 525/900, and the difference in performance was huge!

3DMark06 before: 1,700'ish
after: 2,077 !

RTHDRIBL 640 x 480 window before: ~ 50 fps
after: ~ 70 fps
----> around 40% increase!

W.E.I.: Aero/Gaming Graphics before: 4.1 / 4.7
after: 4.8 / 5.2

The good news is that my load temp has only increased a few degrees:

before: 72C
after: 75C

Dell :: NVidia 8400m GS

Dec 6, 2008

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?

Anyway here's my system:

XPS M1530 Laptop: Intel Core 2 Duo Processor T8100 (2.1GHz/800Mhz FSB, 3MB Cache)

3 GB DDR2 SDRAM 667MHz (2 DIMMs)

320 GB SATA Hard Drive (5400 RPM)

128MB NVIDIA GeForce 8400M GS

If anyone knows anything about Turbo Cache or how this card performs with World of Warcraft.

Feb 28, 2010

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?

Dell :: M1530 8400M Vs 8600M

Jun 5, 2009

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.

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..................

Tried a G.Skill 4GB module in the M1330 this evening.

It is not recognized in slot A or B. This was tested with BIOS A08 and A12. This unit was purchased in March 2008.

It's a no go for this model it seems.

Sony :: SZ6 Abruptly Powers Off. Nvidia 8400M GS

Aug 26, 2009

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

Sony :: Is Copper Mod Necessary On Vaio FZ190 With 8400M GT

Jan 4, 2009

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..

HP/Compaq :: Maybe This Is The Reason Why The 8400M And 8600M Keep Failing

Jul 23, 2009

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.

HP/Compaq :: Where Is The Shader Clock- Dv2700 / 8400M GS

May 11, 2009

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)?
