Graphic Cards :: NVidia GeForce 640GT Using 25% Of System RAM
Aug 24, 2013
I have a 2GB GeForce 640GT video card. It has 2GB onboard and windows 8 is using an additional 2GB of ram for it. I don't do gaming or heavy rendering. Occasionally I use google earth and a few other 3d mapping apps. I don't see how any of these need 4GB of ram to do this. This 2GB of system memory is 25% of my entire system memory. This card, in an older PC used no system memory under Windows 7.
How can I reclaim this ram? If I cannot, and add more ram will it take even more of that?
nVidia says this is a windows issue and not a driver issue but I cannot find anywhere in windows to tune or change this.
See the attached System Information from the nVidia control panel.

I installed an EVGA GT630 1GB but it doenst work properly with Windows 8 Pro x64. All I have is a black screen, but the computer isnt freezing, 'cos I can hear the logon and shutdown sounds. I've tested it on Server 2003 R2 x64 (XPDM) and it worked just fine.
I got noyhing from nVidia forums...
May it be a problem with WDDM (defective card)?

Recently, I got a new graphics card for my computer (the card was Galaxy NVIDA GEForce 620). Well, after install some things changed that I do not like:
I can no longer sleep my computer. The #1 thing I liked about Windows 8 was getting to sleep the computer/ wake it up real fast. After I put this card in, the only options I get are Reboot and Shutdown. (And I even had to turn fast startup off, because when I start the computer up with it on, my USB's loose their functionality).

So I bought an MPG645 which is actually a Medion and I have a GeForce GT640 (which should work fine with Windows 8). First time when I installed the card I got the beeps (long short short) and nothing happened. Went into bios and noticed I had an "OS selector" for either Windows 8 and Win7/OtherOS. Setting it to the Win7/other OS solved the beeps and I could use my GT640. Now yesterday I had a big problem resulting in me needing to get back to factory default so as I am used from the previous OS setups I removed my videocard, set the bios back to original and re-installed my system
Then I wanted to put my card back.....black screen (after setting the OS back to WIN7/otherOS). tried it without the card and got a message telling me I had to use the proper boot device, hit any key and try again". The solution I was reading on the nvidia page told me to disable secure boot, no solution.
Basically, it has worked fine until I had to reset my system and now whatever I try I can't install my graphics card
My info:
Windows 8 64bit desktop
Motherboard
ManufacturerMEDION
ModelMS-7797 (SOCKET 0)

I have recently installed a new Video Card a Gigabyte GeForce 660 GTX, when I'm playing video's or if I open the Geforce Experience program from the task bar the screen goes blank for about a second then returns to normal, it always seems to happen when I get the program to check for updates. I am using the latest driver 320.49.
When I play games there's no problem occur so I don't think it's the card it's self, I suspect it's something to do with the program.

Yesterday I was playing Dota 2 when suddenly I got a black screen and "display driver has stopped working and has recovered."
Right after, I tried to open the game again. There was no way of getting it working.
Any other game was also not working. The first thing I did was, of course, trying to reinstall the driver.
I tried to install the lastest driver (337.50 beta) and I got only "installer has failed". I also tried with many other older drivers and such, with no result.
Other things I tried:
Clean install (from custom install options)Hard clean install (Deleting all nvidia files before)Display Driver Uninstaller safe mode + reboot and install (same error)Install in safe mode (installer error)Register again WMI files (nothing changed). Take ownership of various folders containing drivers (nothing changed)Directly install INF files using devmgmt (gives error code 28) Changing some registry values regarding vbscript that fixed it for other people. Use Windows Update. "1 update was not installed" + error 80070002sfc /scannowRollback from devmgmtRestore to a early system point where it was working (couldn't restore, no matter what point I choose)
Nothing worked. It just won't install. Now I'm stuck with Microsoft base driver and can't play anything.
Here's the installer log, the only part with errors: Log (full log attached)
Event viewer shows nothing.
My system specs: CPU-Z Validator 4.0
I think it's probably a miracle if I get this working without refresh/reinstall Windows.

Once I have updated driver for NVidia, Wn 8.1 does not start. Entering Safe Mode I could uninstall the update and everything goes back to normal.

I have a notebook pc that comes with windows 7 from factory. I would like to install windows 8 in my machine. It has integrated intel hd graphics chip and separate nvidia geforce 420m graphic card. I heard switchable graphics are not working fine with windows 8. Is that true? BTW my system manufacturer isn't providing drivers that compatible with windows 8. Whatever windows 8 upgrade assistant says already installed drivers also compatible with windows 8 and individual hardware manufactures has windows 8 compatible drivers. So, what should I do? Windows 8 upgrade is useless for me?

I am having is my Windows 8 x64 has tons of artifacts and the mouse leaves trails that's even if it lets me into windows... however when I use the same setup on my Windows 8 x86 there are no artifacts...oh and same on Windows 7 Ultimate x64. I am aware that there are still some known issues with Nvidia Chips on x64 versions of Windows 8.
Example 1
Example 2
I have tried several different things and nothing has worked so far...

So I recently bought a new computer. I was using the GTS 450 on the old one no problem not even a month ago. I have attempted to install it on my new pc. Switched out to a Thermaltake TR2 600W PSU which is operating just fine. I placed the video card into the primary pci slot and powered it with the 6-pin connector. Put everything back together and started her up. PC turns on fine, with even the fan going on the video card. But no video output. I'm stuck. What can I do? The drivers won't install themselves without the hardware.

I will try to post a dump file the next chance I have in getting into safe mode. I have an Asus CM6870-CA010S with the NVIDIA GeForce GT 640 card. It has been running like a dream since I got it in April, then I performed the 8.1 update, and innocently updated the drivers. Bad plan. For the past week I've fallen into the labyrinth of uninstalling the card, subsequent iterations of the drivers, clearing registries, performed the "Refresh," all after reading the forums here, on Nvidia's boards, anywhere I can get logical info.
I finally found what I thought was the perfect recipe, uninstalling totally in safe mode, deleting the folders orphaned from uninstalls, cleaning the registry, disabling Window's automatic downloads for drivers and hardware... etc. I had solid uptime for an hour, and I'm not a gamer, and hadn't yet tested my main objectives- Photoshop and Premiere. But HD video was great, and I finally thought I had it licked. Then, black screen. I have no BSODs. The system seems to shut down so fast that it doesn't have time to make dump files, and WhoCrashed.exe keeps pointing to nvlddmkm.sys as the culprit when a dump is made, with either pagefile or IRQL not less or equal errors. I'm so done.
After trying virtually every solid recommendation I can find, I'm about to throw in the towel and either get a whole other brand of graphics card, or take it to the super expensive judgmental hipster repair shop. This post is my last hope, and I'll try to get a dump file the next chance it gives me enough uptime to collect one- and getting into Safe Mode with F8 is seemingly very random.

I bought myself a Radeon HD 7770 a few months back to replace an old GeForce 9600GT. A few weeks after installing the AMD card, I was going through my programs cleaning out old files and decided to remove all the Nvidia stuff. I removed the drivers and stuff and upon reboot, my computer would no longer boot to the desktop. I ended up having to use system restore to get the computer working again...
Fast forward to yesterday. I upgraded from Windows 8 Pro with Media Center to Windows 8.1 Pro with Media Center, and I started experiencing the same problem listed here: "Win 8.1 desktop right click takes 15 seconds!" I tried the same solution that was found and it did not work for me. My guess is it had something to do with the Nvidia driver software still being installed on my computer. So I again attempted to remove the drivers. At this point I couldn't even remove the Nvidia software as nothing happened when I pressed the uninstall button. I ended up having to reinsert the Nvidia card, and reinstall the drivers, in order to uninstall the drivers. After I restarted and reinstalled the AMD card, the computer, like before would no longer boot to the desktop. All I would get was a mouse pointer that would appear and disappear every couple of seconds and a Number lock button on the keyboard that would be turning on and off at the same interval. If I reinsert the Nvidia card the problem goes away, but obviously I don't want to keep the old card in my computer.
My question is: Why would the computer boot with the Nvidia card when the Nvidia drivers are uninstalled and yet not boot with the AMD card when the AMD drivers ARE installed?

I have a laptop with one VGA port but I wanted to connect it to two extra monitors so that I could create a triple monitor system. I bought a VGA splitter to be able to connect all monitors but what I discovered is that it still recognizes it as a second monitor. I have the screen on my laptop extended with the second one but I cant extend the second one to the third one. It just duplicates it. Is there any way I can download software to make it recognize the third monitor?

My Intel HD 4600 graphics puts 3 little apps to be started automatically. I know they are related to: intercepting hotkeys - hkcmd.exedisplaying tray icon - igfxtray.exedisplaying settings GUI - igfxpers.exe The thing is that I don't use hotkeys and have disabled them in Intel Graphics options, I've also removed Intel Graphics icon from the tray.
Thus, I'd expect the first two Intel apps to be removed from items set to auto-start at system bootup. However, they are still there. Is it correct? Shouldn't they be disabled when related functions are turned off?
Is it safe to simply delete the related registry entries and leave only the last app?

I have asus n550ja laptop with 8gb memory, the shared system memory is 1760mb, I usually don't play any games, there is no reason I can use that much graphic card memory. But because of the high shared memory, I cannot use all possible memory for virtual machine or ramdisk, when I use those, they can only maximum use about 6.5gb memory and cannot go higher. So I wonder is there a way I can reduce the intel graphic card shared system memory?

My computer is hp envy dv6 7280sf notebook with 2 GPUs intel graphics HD 4000 and Nvidia Gefoce 630 M running windows 8 64x.
After making an free upgrade online for windows 8.1 which run successfully, both gpus were ok...
But after receiving a windows update with new drivers for intel graphics 4000 gpu , after install and restart , the computer freezes on blank black screen at windows startup with no mouse or anything only backlight.
So safemode was succeful but i figured that the update for windos update was the cause and graphics drivers were installed so i removed the drivers for intel graphics and itried to reboot the computer so the restart was succeful but the intel graphics card was unistalled and no drivers were automatically installed so i tried to download and install the drivers from hp and intel website for windows 8.1 however the install fails.
Automatic install from device manager failed both online and from computer and even from manual driver selection.
So therefore the install failed in safe mode , and the high def audio device ( on screen audio possibly) failed and the device was not recongnized (no drivers installed) so i'm stuck without anydrivers for the integrated gpu and the games are no longer able to run normally even if the nvidia card is on.
I tried downloading an installing Windows 8 drives but it failed to install also , for instance any new install of drovers seems to fail for me even for external usb hard drive.

I'm building a system for cryptocoin mining, and am having a little problem with getting Windows 8.1 (home, not pro) to run the 3rd card (GPU) My equipment is:
Gigabyte 990 FXA UD3 MOBO
AMD Vishera CPU
2x4 gig Corsair Ram
3x Sapphire r9 280x Video cards
1000w Corsair PSU
Scandisk SSD
All parts are brand new.
Here is the problem... everything boots just fine and runs with 2 of the GPU's installed. I have the latest AMD 13.12 drivers, and the AMD APP SKD installed. When I add the 3rd GPU though, windows will auto detect it as a Radeon 7900 with the caution sign, AND/OR a r9 200 series card, also with the caution sign, most times BOTH. Then it randomly freezes the system. A couple of times I got it to run long enough just by luck I guess, to install the 13.12 drivers on the 3rd GPU, but then in a few minuites the system would freeze again.
2 GPU's run just fine, the problem only shows up when the 3rd card is installed, and it happens on any of the 4 16x slots, or both 1x slots on the MOBO. It doesn't matter if the GPU's are directly on the MOBO, or on 1x16 risers. There are plenty of folks running this set up with up to 6 GPU's, so I know it can be done, but I must be missing something somewhere in the windows set up.

I've got a bit of a strange issue that I haven't had with previous OSes on this PC. I'm running a Dell OptiPlex 380 with Win 8 x64 at the office and I have to run 2 video cards for all of my screens. I have a GeForce 8400GS in the PCI-E slot and a GeForce 6200 in the PCI slot.
Previous to the Win 8 install, it worked fine. Booted exactly as I had shut it off. Now, with 8 - it's killing my PCI-E card presumably when it puts the screens to sleep when I leave for the day. So I'm coming in to all of my windows being moved to the PCI card's monitor (only one hooked to it) and I have to reboot to get PCI-E card to come back.
If I check the screen properties, I see only the screen hooked to the PCI card. I've changed the setting in the BIOS for the first video card to Auto and also tried the PCI-E selection and it's the same either way.
Why on earth would it default to the PCI card rather than the PCI-E card?

i am on windows 8.i am using HP laptop.this is my ccc version.
i got 2 problems:well first one is that i can't update to windows 8.1 as the update always hang on 82% and after that my laptop
automatically shutsdown i don't know whats the reason is and that's why i am stuck at windows 8 till now although have 8.1 ISO but i don't want to install it as i have to erase my my windows 8 which came pres-installed so i will loose my genuine windows 8 .now i want to know what if i open the 8.1 installer and install it from a virtual tool like Deamon although it gives an option to keep files app setting safe but i fear that it would conflict with 8 and i would have to format my laptop then ok now to the major problem i just recently purchased Watch Dogs and installed it.I played the first mission and got busted so the mission failed and it began to reload and then a error pops up saying watch dogs have stopped working upon googling i found out that this is due to DUAl AMD Graphics so they stated that i should disable it but i cant find any option of disabling DUAL Graphics.

I just decided to turn loose Windows 8 RP on "bare metal" here as opposed to a VM. I didn't even bother to mess with video under a VM, but with the bare metal install, I've run into some trouble.
At first, media player didn't seem to play anything, including .wmv files. Messing around, I unchecked the "Direct X acceleration" box and that allowed it to play .wmv files. However, it still won't play .mp4 files -- no video, just sound, and Media Player will hang trying to exit.
It did this with a clean install with only the Windows supplied video driver. My video card has been obsoleted by AMD now (HD 4200 chipset) and I couldn't use the new Windows 8 preview driver package, but I did try installing the AMD 12.4 driver in Win7 compatibility mode. That worked fine it seems, but it still won't play .mp4 files. Turning the Direct X acceleration back on still kills .wmv playback as well.
Win7, both x64 and 32-bit played .mp4 files fine right out of the box on this machine.

I'm having issues with one of my GPU's fans (it features a dual-fan cooling) and will have to fix it soon. The problem is, it's making an annoying noise and I was thinking if I could just block it for the time being, however brutally that sounds.
So, the question is - provided the GPU doesn't reach critical temperatures (I'm going to monitor this obviously) - would this create any additional risks, like overcurrent or something? (I don't play games, but it's a HD6950, so it does emit a lot of heat).
