3.86GB usable with discrete graphic card????

the system tells me
memory: 4.00GB ( 3.86GB usable )
i have a discrete graphic card on my t510
and my system is 64 bits
how can this be happened?

Yeah same here with my G555. In both XP and Win7 it says 3g with 2.7g usable. But I'm not sure if my GPU is dedicated or not? In XP it only shows 700mb. In Win7 it shows 256mb dedicated and can share up to 1.1g for a total of 1.4g. Weird to me. But I'm loving Crysis on high though.

Problem with discrete graphic card and DirectX 11

If I try any application to launch with discrete graphic card (nvidia geforce 740m) that using directx 11 it always crashes.
There no problems with directx 9 on on this graphic card.
There are no problems with integrated graphic card whether application using directx 9 or 11. Problem occurs only with discrete graphic card and directx 11.
The things that i did:
- Reinstall Windows
- Install latest driver updates (I also tried to uninstall latest and install recomended driver downloaded from the oficial HP support 'driver download' web page)
- different options on nvidia control panel 3d settings page
I also tried microsoft 'Direct3D Tutorial Win32 Sample' source code to build and debug. It is failed in function IDXGISwapChain:resent with code DXGI_ERROR_DEVICE_REMOVED and ID3D10Device::GetDeviceRemovedReason returns DXGI_ERROR_DRIVER INTERNAL_ERROR.
Is there any chance that is not hardware malfunction?

@Enegue ,
Hello and thank you for posting on the HP support forum. In your situation I would consider keeping with Directx 9. The reason I say this is your notebook is not a performance gaming machine. It is designed to be fore general use.
Some cards will notice issues when upgrading to direct 11 from a lower level.
Not to mention with your notebook you will want to stick with the drivers only provided from the HP support site. They are proprietary for the notebook and could be the reason why the directx 11 is not working.
Here is the link to your systems supported drivers.

Is it possible to get a T61 with discrete Graphic card and NO OS?

Hi
Thank you for reading my post.
I am looking to know whether I can get aT61 with discrete Graphic card and NO OS?
I dont like to pay for the OS as I will install Ubuntu.
Thanks

Windows 8.1 freezes while booting up with discrete graphic card T520

Hi all,
Hoping someone can help me here. If I use my discrete video card (nvs 42000m) to boot into windows, it will freeze on the sign in page or sometimes on the metro page however when Optimus is enabled it works just fine.
So I thought it was a driver issue. I went to Nvidia and downloaded their latest video card driver for windows 8.1. No help
Uninstalled that, went to Lenovo's support site and installed their recommended driver and all other windows 8 drivers. Again it would freeze
Booted into safe mode uninstalled that, turned optimus back on, and this time used Windows update to install my video drivers (intel and Nvidia both this time).
Didn't work. So I spent maybe another hour or so fiddling and after many restarts i finally found the culprit. It was the Lenovo monitor driver. As soon as I uninstalled that, everything worked fine and I could finally use my laptop with optimus disabled and discrete video card enabled.
Windows update keeps recommending me to update the monitor driver but if I do, then it freezes again so I'm just leaving it as the default generic monitor.
The reason why I made this thread is to inform and save potential users in the future who have a similar laptop to mine (t520 with hd 3000 and nvidia 42000m) with Windows 8 installed and they happen to choose to solely run their laptop with the discrete graphics card, remember to uninstall your monitor driver.
I am open to recommendations and other alternatives.

T500 with discrete graphics card availability

Im close to purchasing a T500 but have 3 questions.
1.) The T500 with discrete graphics no longer appears available on the canadian site. Can anyone confirm when it is likely to return?
2.) I want to get the keyboard change to the T61 (I have used the T500 keyboard and it is not fantastic) Can I order this when I place my order for the T500?
Cheers

1) When you are in the advanced mini dock, the displayport is active, so is your VGA and DVI. I am using the displayport on the laptop driving a Dell U2410 at WUXGA resolution, and the DVI port on the dock is driving another Dell U2410 LCD.
However, if you have a switchable graphics card and you switch to intel gpu, then the dvi port on the dock is disabled, only the the vga would work.
2) To your question of your the laptop's vga and displayport driving these monitors the answer is yes. The VGA on the T500 should be able to drive a WQXGA (not recommended as the picture quality is heavily degraded) and the displayport can also drive WQXGA.

Computer freezes when switching to discrete Graphics Card.

Hi! I have a W530 with the K1000M graphics card, along with the Nvidea Optimus program. Whenever I run a program that uses my discrete graphics card, I get the error "Display driver stopped responding and has recovered." I've used my discrete graphics card before with no problems, although my computer has had two major changes since the last time I've used it (see notes below).
Solutions I've tried: Updating with the correct drivers through Windows Update (update failed), updating driver through Lenovo website (broke display), updating drivers through Nvidea website (driver installed, didn't fix problem). Nothing works, and the Lenovo driver basically disabled my display. It took me hours to fix just that-- for some reason, whenever I crash, my computer looks at drive X instead of C. Had to screw around for a while just to let me do a system restore.
I'm rather upset about the whole thing because I really like my laptop. Right now, I've just set Optimus to never use the discrete graphics card...
Thanks for reading!
*Note 1: I have some aftermarket parts: Crucial RAM and a mSATA SSD. I've had these parts in for over a year with no problems.
*Note 2: The motherboard in my laptop blew a transistor or something a few weeks ago. My university's computer shop replaced it under warranty.
*Note 2.1: I'm not sure if the new motherboard is causing the problems or Windows 8.1, or something else entirely. I haven't used my discrete graphics card since before both the 8.1 update and my motherboard being fixed.

This happened to me whenever I was trying to run 3dsMax Design 2013 in Optimus mode, everytime I attempted to open that program it would simply refuse and say the nvidia driver had just crashed.
It was solved with nvidia 305.93 I think (I currently run 331.82 which is the latest) look for the most up to date driver at the nvidia drivers download page.
That is really an nvidia driver related problem but you should also update your Intel video card driver too as previously suggested. (and if the program that is crashing is an Autodesk product be sure to be up to date too (with all the nuances that it implies), I'm currently running 3dsmax 13 PU6 and it works)
So what you need to do is to uninstall your nvidia driver completely, reboot, install the most up to date from nvidia. reboot, via windows update install the lates Intel video driver (if something appears) (don't install it from the intel web site). In device manager my intel driver appears to be 9.17.10.2843
(Maybe it didn't work the last time for you because maybe you didn't perform a clean installation)

How can I test my discrete graphics card in an MBP Retina?

How can I test the hardware on the discrete Nvidia grpahics card in my late 2012 MBP Retina?
I've had a *lot* of problems with it which I won't repeat here but the latest fun thing it's doing is crashing and requiring a hard reset any time *anything* attempts to access the discrete graphics card. This includes but is not limited to:
*Opening system profiler and clicking on Graphics (it displays a blank screen)
*Running a 3D graphics benchmark
*Running intensive mathematical calculations on the GPU
*Connecting to an external monitor with the thunderbolt port and using the computer for a short period of
None of these things actually work and after unsuccessfully attempting any of them the computer becomes very unstable shortly there after and usually crashes and requires hard reset. One time I got a crash report that said something about GPU panic.
Any recommendations? I get the sense that the apple hardware test is not doing a thoroough test of the GPU if at all.
Thanks.

If they add OSX support for this product and it comes in at a reasonable price point, it could be an attractive solution.

Also, there are products from other companies that allow connection to PCIe cards through thunderbolt. These two are geared more towards professional use (Audio/Video I/O cards).

Do I need the discrete graphics card?

I'm buying a 15" macbook pro in the next couple of weeks. I do lots of work on Adobe Lightroom and Photoshop. Do I need to get the top model with the discrete graphics card or is it not worth the money?

No, it's certainly not geared for gaming! If you do a lot of Photoshop work with 3D renderings, actions, etc., a discrete GPU can be great - particularly one with 2GB of Video RAM. If I were in the market for a new machine, I would certainly purchase the unit that has the discrete GPU.

Does the Advertised T410s with Discrete Graphics Exist?

On Lenovo's website (even on the purchase page) it says you can get a T410s with a Nvidia discrete graphics card, however I cannot configure one with that option. Does anyone have a link that shows the T410s with this option?
Maybe it will take them a month or so to get this option activated.
Thanks All,

the ones with discrete graphics are "announced", but not "available" yet
i think it'll be available in march or something

Is anyone still having discrete graphics card problems after replacement

Is anyone still having discrete graphics card problems after replacement?
Macbook Pro eligible for replacement through Apple program.
Submitted my computer 2 days before program came into effect.
They replaced card or logic board with same original model: AMD Radeon HD 6770M 1024 MB
Issued me a refund check for my repair.
Seems to have some noticeable issues, fan running more than usual again, and temporary graphic lines,
but disappear too fast before a screen dump...
Is anyone who has participated in the replacement program received a different graphic card for
Model Macbook Pro 17" (late 2011)
Thank you for the reply.

Unfortunately I have yet to call AppleCare because I am on a project for 3 weeks and cannot be without my laptop during that period....
Until that time I am trying to figure out what I can do to protect the Palm Rest/Mouse Pad area of my Macbook once they either fix it or give me a new one. Has anyone had any experience with either of these products that can provide some input as to whether they are good or bad?

Thinkpad Yoga 15, discrete graphics card disabled

I just purchased a Thinpad Yoga with a discrete graphics card, NVIDIA GeForce 840M. It's disabled. I've tried the most recent driver from NVIDIA and the driver on Lenovo's site -- version 9.18.13.3360
Anyone have any idea about this?
Solved!

Hi Horseatingweeds,
As per the screen shot I think the drivers may have got corrupted, uninstall both the graphic drivers and run ThinkVantage System Update utility, and make sure whether the drivers are not updated from MS updates.
That seems a little old, so I looked around. There are later versions, up to 1.24 4/6/2015 for ThinkPad S1 Yoga: http://support.lenovo.com/us/en/downloads/ds038334
Please do not update the BIOS manually, instead of that run ThinkVantage System Update utility to check for the exact drivers and application for your system.

Hope this helps.

Discrete graphics card not detected.

First post.
System specs:
Mobo: MSI Z77A-GD55
CPU: Intel Ivy Bridge i5 3570K
GPU: eVGA GTX 580
PSU: NZXT Hale82 750W 80 Certified
RAM: G Skill Sniper Series 1866 8Gb DD3
SSD: Corsair Force Series GT 240G
For starters, I was running a CoolerMaster 1000W PSU and the eVGA 580 GTX in my old system. Upon upgrading, I transferred those units to the new system but can not boot up system with GTX 580. Onboard graphics work fine, so I went ahead and installed Windows onto the SSD with no problems. Once in Windows, I installed the latest Motherboard updates, and even flashed the BIOS to latest 1.4 build. Still no luck with the graphics card working on boot up.
Things I've tried:
- GTX 580 boots up and works fine (hence the system running now) on older Motherboard.
-Ruling out a defective GPU unit.
- Both Coolermaster and NZXT PSU run the GTX 580 on older Motherboard.
-Ruling out a defective PSU unit.
- Graphics card (GTX 580) would not boot up on ASUS P8Z77-V Pro Motherboard, nor the new one MSI Z77A-GD55
-Possibly ruling out defective Motherboards.
- Replaced i5 3570k CPU with yet another i5 3560k CPU (Same issue)
-Ruling out a defective CPU
- When using onboard VGA, I can get into the BIOS and the Graphics settings are set to PEG (PCI-E Graphics). Although when I shut down and install my GtX 580, still no boot up.
- Moved the GTX 580 between the 2 top PCI-E slots, to no avail.
- Moved 1 stick of RAM between the 4 DIMM slots and still not working.
-Reseated graphics card and made sure the 8-pin and 6-pin connectors were firmly intact.
I have done a lot of research, but have yet to find a definitive answer to my problem. I'm not ruling out a 3rd motherboard that may be defective, but I feel this is highly unlikely. Again, everything works and checks out in the system specs with the onboard graphics enabled.
I thought I'd try here to get some addition ideas from the group. Thanks for reading.

Try this; Shutdown, remove the discrete card, connect to the onboard, restart and boot all the way into Windows, restart to the UEFI/BIOS, change the graphics setting to IGD, save and enter, let it reboot into Windows, hard shutdown. Restart into UEFI/BIOS, change graphics setting to PEG, save and enter first, then hit the reset button and enter immediately back into the UEFI/BIOS checking to make sure the PEG setting is in fact set, then hard shutdown. Install the discrete card connecting all the power cables and monitor cable, start and see if it now boots into Windows with the graphics now working.
This merry-go-round procedure worked for me on 3 Z68's, no reason it won't work on a Z77.
I will try this procedure now. If it works, I will have to buy you lunch because I have NEVER heard of such hoopla!

Discrete graphics card not switching off - kernel 3.18

Hi there,
I'm currently running Archlinux on an Acer 4820TG laptop with two graphics card: Intel (onboard) and AMD Radeon HD 6550M.
After upgrade to kernel version 3.18.2-2-ARCH, the command echo OFF > /sys/kernel/debug/vgaswitcheroo/switch that I've been using doesn't switch the discrete graphics card off.
This way battery drains rather rapidly
Additional info:
Intel driver: xf86-video-intel 2.99.917-1
Radeon driver: xf86-video-ati 1:7.5.0-1
Help would be appreciated. Thanks!

Discrete graphics card performance drop after overheating

Recently I played Amnesia: The Dark Descent on my pc while overclocking slightly using Sapphire TRIXX. I changed GPU clock from 750 to 84x and memory clock from 900 to 10xx. During a cinematic the com crashed, ctrl at del failed to load up but sound was still coming out. I left it like this for2-5 min before force shutdown. When I turned on my laptop again n tried to play games there was a huge performance drop. Games running at 60 fps turned to 20 plus when using dedicated graphics card only ( I disabled dynamic mode n used fixed mode while playing amnesia also, which means I was purely using the dedicated graphics card.)
My laptop is a hp dm4 3005tx Beats edition, with Intel I5 2.5GHz processor and 8.00 gig ram. I also disabled paging file on my laptop btw, regretting this .
can some1 tell me hw to fix.this problem or can I replace my discrete graphics card? Because my laptop has Radeon hd 7470m and Intel hd graphics

The graphics card is soldered on so no replacement. I would do a wipe and reload of the OS and stop overclocking laptop video cards. They are too sensitive to heat and other issues. You are asking for trouble, and may have already found it. At a minimum run DriverCleaner and remove the video driver until you get back to a low-res screen generic vga hardware and then reinstall the best driver you can find.
