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?
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 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 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.
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?
I have aÂ HP Pavilion dv6700t CTO Special Edition Notebook PC running Vista. Â The laptop screen goes to 1280 x 800. Â What is the highest resolution that the NVIDA GeForce 8400m GS will supportÂ on an external monitor? Â There is an HDMI port on the Â laptop.
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?
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?
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 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 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)?
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...
