W540 Graphics Card Clarification

I had one clarification regarding the graphics card I chose for W540 which was "W540 NVIDIA Quadro K2100M 2GB" but when I got my spec confirmed it was changed some thing like "NVN15P-Q3Opt(K2000Mfollowon) Graphic Card".
Are both these represent the same thing or the one I got is something different.

Hi gaugeta123
If I am not wrong. NVN15P-Q3Opt(K2000Mfollowon) is just a codename for NVIDIA Quadro K2100M 2GB. So, technically both are the same.

  • Graphics card clarification requested

    Hola - I've been reading through the threads to try and figure out the best upgrade from my Radeon 9600 Pro (Dual 2GHZ, PCI-X, 23" Apple Cinema HD, May '04). From this thread...
    http://discussions.apple.com/thread.jspa?messageID=9089248&#9089248
    it appears these are my best choices....
    Radeon 9800 Pro
    Radeon 9800 XT
    Geforce 6800 GT
    Geforce 6800 Ultra
    Radeon X800XT
    Radeon X850XT
    Geforce 7800GS
    Is this correct? Is there anything specific I need to look for? And what's the difficulty in flashing a graphics card? I've done it for portable and mobile devices, but never hardware. TIA

    Hi-
    The Geforce 7800 GS will give the most HP, and OpenGL should be no problem.
    The 6800 GT sports full support through OpenGL 2.1, and the scores (with OpenGL Viewer) are almost double that of the Radeon 9800 XT.
    7800 GS is the same as the 6800 for OpenGL support, and I expect the benchmarks for OpenGL to be way higher.
    The 7800 GS has 40 GB/sec memory bandwidth and handles Vertices at the rate of 600 million/sec.
    Considering the cost of the other top contenders, especially the Mac edition X800 XT, X850 XT and the little brother to the 7800, the 6800 Ultra and GT, the 7800 GS is not only the top of the heap for 8x AGP in a Mac, it is also the best buy at avg. $250 for a flashed BFG OC 7800 GS (most desirable IMO).

  • High CPU usage when graphics card is put at work

    I have a 13inch Air with 2GB RAM and 256GB  with Windows 7 Ultimate 64bit. All possible updates have been installed.
    I noticed some tearing when trying to move program windows across the screen so I started checking the CPU usage. I saw that it is spiking to 25-35% when moving a window across the screen.When you drag down a window you can see the different copies of the top bar across the screen. Not smooth at all like on a standard PC windows system. Same issue when scrolling through webpages which spikes the cpu
    I also noticed a high cpu usage when playing mkv files 25-30% while on an Atom HTPC i get a lower load playing the same file. The Air should be faster than an atom with a nvidia 9400m when playing video files.
    I already tried updating the nvidia files to the latest version on their site by hacking the driver inf but this did not resolve the issue.
    Has anyone experienced the same or know what could be causing the beavior?
    Many thanks

    Maybe my initial post was not clear so let me add some clarifications.
    I have the problem with Aero disabled
    I have the problem on the Apple site which does not have any flash content.
    I have already hacked the lastest nvidia drivers to get them on my system which did not change anything. Can you provide a link to some other 'supported' beta drivers?
    I am using the new 13 inch air so it has the newer graphics card so I would expect it to be faster than an old HTPC with a 9400m in it. I wasn't stating that my Air had a 9400m.
    It would be great if someone you also do the test to check the cpu load:
    - when playing a 720 mkv
    - when dragging a window across the screen
    Just open task manager and see if the CPU spikes.
    Many thanks!

  • Most appropriate graphics card option

    Hi everyone.
    I have an early MacPro (v1.1). I opted for the ATI X1900XT card upgrade when I purchased it. Like most other people on this forum, I encountered annoy issues such as lines appearing on screen, 'sparkly artifacts' and constant freezing. Even after cleaning out the dust from the graphics card's heatsinks and fans the problem persisted. So I then decided to install a thrid-party cooler system for the card. This changed nothing - I think the card has baked. Upgrading to snow leopard has seen some reduction in freezing but thats probably cause I'm running SMC fan controller at full blast, with the door open (not too crazy on that btw).
    Enough is enough. I'm upgrading. However I'm a wee bit confused.
    Yes I know that some "unsupported" cards such as the ATI HD4870 work with my mac.
    Should I play it safe and go with an old GeForce 8800? or the HD3870? or the HD4870? or.. shudder purchase another X1900XT (that would have to be last resort, the price is outlandish for such an old card).
    I will need to run two monitors for a bit (unfortunately both are VGA, via DVI adapters). One poster on another forum warned against the HD4870 for that reason. That sounds remarkable that the adapters wouldn't be compatible.
    I'm using this machine primarily for editing. Gaming is of no interest here. Unfortunately, my knowledge of graphics card's inner workings are limited.
    Many Thanks,
    Dave.

    I also understand that my MP would be PCIe v1.0 where as these cards use v2.0 - this is backwards compatible (please, correct me if I'm wrong) and in the worst case, I might not get the full bandwidth of the card. Still, a working, decent card is enough to satisfy me.
    Price has become a factor - its looking more like I'll wind up getting the slightly older HD3870. That goes for AUD$475. These "mac tax" prices are ridiculous! Or the other option is go get a HD4870 via eBay, or OWC (which with shipping is still cheaper then any store in Australia).
    8800GT is still available at one online store in Australia, for the ripe price of $500. Considering the price of it, I'd rather not invest in an older card.
    I guess what I'm asking is people's experience and opinion on the HD3870 vs the HD4870.
    And a clarification - the whole VGA thing; my monitors are LCDs, they just run through a VGA interface. The "analogue" support issues seem to be CRT related (again, please correct me if I'm wrong).

  • My macbook pro 2.2ghz, i7 , early 2011 having problem with the graphic card

    hi, just need clarification, that i was made to understand that the NVDIA graphic card installed in Macbook Pro, has a warranty of 3 years, eventough without Apple Protection Plan. Can someone clarify this , as i m having problem with it now.

    No, the GPU does not have a seperate 'three year warranty'... unless you purchased the extended AppleCare Protection Plan.
    If you feel that you're having problems with your GPU, take your machine to your local Apple Store or an AASP and have them run a free diagnostic test. If the card is faulty, and you don't have a APP, you'll have to pay to have the entire logic board replaced.

  • After choosing the graphics card (Quadro 4000) as recommended by adobe  ..we have problems....

    After choosing the graphics card (Quadro 4000) and then adobe as the partner the following applicatons are shown. I have noticed that the only CS6 product is the Premiere Pro CS6 but we do use the whole Adobe Master Suite.
    Can Adobe please provide clarification on what version of driver is required for the Adobe Master Suite CS6 when using the Quadro 4000 graphics card in windows 7 64bit (pro)
    We are having constant problems with crashing programs ACROSS the SUITE,unsee-able footage,drop frames on outputs( reguardless of WHAT SETTINGS.) and system lock ups. All  codecs are on board ,Our I T staff and production staff are pulling their hair out as one conflict /problem is resolved , another is created somewhere else.
    have tired latest  recommended drivers and rolled back  a few. still NO resolution.
    THe systm   has,at adobe 's tech recommendations, had adobe cleaner remove ALL and cloud has reinstalled all of the master suite. still no resolution.

    This could be a combination of factors or a bad Quadro card of which I would not be surprised. You may want to contact me direct on this one so I can remote in and see what is going on.

  • Can't Update Boot Camp Graphics Card Driver

    Greetings,
    I have an iMac (2011) running 10.7.2
    I created a windows partition (windows 7 Ultimate edition) which has played Crysis II, Fallout New Vegas, etc.
    I recently bought Battlefield 3 and, when I try to run it, it says that my Graphics Card Drivers are out of date. As a result, the game continuously crashes (despite the iMac easily being able to run the game).
    What are my options for updating the drivers? I know that updates are usually in the form of software updates, directly from Apple.
    Am I simply screwed until they decide to update their drivers?
    A little clarification: I'm trying to install the "catalyst mobility 64-bit utility" for Windows 7 (64-Bit).
    When I try to update my driver, through the AMD website it says
    "AMD Catalyst Mobility cannot be downloaded due to incompatible hardware/software on your computer. Your computer does not contain a proper graphics adapter"
    Any ideas?

  • Switching graphics card when on battery

    I have a W540 with the nvidia K1100M graphics card. I'm trying to configure my laptop so that when I'm running on battery power, ALL programs use the integrated graphics adapter. When I'm plugged to AC in I'd like ALL programs to use the nvidia card.
    I've looked into the nvidia optimus program, but it seems like it has a different card selection philosophy that isn't quite what I'm after.
    Is there a way I can achieve this? It seems like a very straightforward config.
    Thanks!

    True, but you'd still have to restart all of your existing processes. Worse, if something like DWM ends up on discrete, you'd be stuck with high power consumption until you stop and restart it.
    If the caveats are acceptable, you can probably script switching between "Auto-select graphics processor" and "Integrated only" as found in the NVIDIA Control Panel and set the program list according to AC power conditions. You'd also probably bypass the NVIDIA Control Panel itself and toggle the setting in the registry directly (don't know if it's actually in the registry) or using a CLI tool (don't know of one).

  • CTO 20in imac vs 24in imac graphic cards

    Hi All, was wondering if anyone knows what kind of difference the video card in the 20in imac vs that of the 24in. I'm looking to upgrade soon and pricing my needs/wants of a new system and what I can actually afford. Basically I'll be using the system for general work, WoW, some photo editing and some video editing (pilot presentations and portfolio reels). I had planned on getting a 20in with the upgraded video card, but I noticed recently that there are 24in refurbs at the apple store (30 day wait). When CTOing the 20in with only the upgraded video card and 2gb ram its around the same price as the 24in refurb. Besides the larger screen size, which is better the upgraded X1600 256mb vram in the 20in or the stock nVidia GeForce 7300 GT 128mb. If the 24in can still out perform the upgraded 20in then it seems like a no brainer. Thanks for any clarification anyone can give.

    There is a website that did a comparison of the different core2duo macs. The graphics card on the 24 inch (especially the 7600 GT) outperformed the ati x1600 by a good margin in games. Framerates were well up of the ati cards.

  • Graphics card: What's the difference between NVS and FX?

    I am looking at two graphics cards online for a D20 workstation. One is NVIDIA Quadro 256MB NVS 295, and the other is NVIDIA Quadro 256MB FX380. My question is, what's the difference? They are both the same size, at 256MB, but I'm not familiar enough with graphics to know what the difference is between and FX380 and NVS 295. I've tried looking around online, with no luck.
    Any help would be greatly appreciated. I would assume the differences come in what you are going to use the card for, correct?

    quadro NVS cards are meant for 2D business graphics and driving multiple displays.   most NVS cards run silent as they don't have an active fan -- only a heatsink.
    quadro FX cards are meant for 3D, CAD, multimedia, and heavy graphics processing.
    you can visit nvidia's site to learn more...
    NVS: http://www.nvidia.com/page/quadronvs.html
    FX: http://www.nvidia.com/page/quadrofx_family.html
    if you need specific recommendations then we'll need to know more about what you do (or intend to do) with your system.

  • Macpro VS new imac graphic card

    hi,
    please can anyone help with this:
    on apple macpro page, under graphics i see a benchmark based on quake 4 of the nvidia GeForce 7300 GT(256MB of GDDR2 SDRAM), it results 35fps.
    The same graphic card NVIDIA GeForce 7300 GT on the new imac core 2 duo page, gives 47.
    The Doom 3 bench is 44fps on the macpro and 76 fps on the new imac.
    I'm not a player at all, but i'm going to order a macpro,
    and i'd really like to know why the same card works better on the new imac core2 duo.
    Thanks

    I hope we can get some clarification on these graphical benchmarks because if these are true it makes my 2ghz Mac Pro obsolete before it's even started!
    If you look at the sub-notes for the Doom 3/Quake 4 graphics test you'll note that for the iMac, the configuration nor resolution details are listed where they are for the Mac Pro. It's quite possible that Apple did these test differently. And, differently so on the Mac Pro to give the biggest difference to the ATi X1900XT and the Nvidia Quadro FX4500. Again, they way they did it on the iMac probably played into the strengths of the Nvidia 7300GT over the ATi X1600.
    Personally, I find the number in tests like this dubious at best as you can make them say practically anything you like.
    I'm also wondering if the new imacs processors will be faster than my 2Ghz Mac Pro?
    For some application the difference may not be a lot. Although, for applications that will utilise the additional processor and double the bus speed it won't be even close.
    Additionally, the difference start to appear when you look closely…
    - Single processor
    - Half the per processor frontside bus speed
    - 3GB RAM Maximum which requires a hugely expensive 2GB DIMM
    - No ATi X1900XT or Nvidia Quadro FX4500 options
    - Maximum DVI support of 1920 x 1200 (23" display)
    - Single external monitor support with only a mini-DVI connetor
    - No PCI Express slot (for stuff like eSATA)
    - Single hard drive as opposed to 4 and potentially 5 (also means no RAID and no Raptors)
    - Single Ethernet and no jumbo frames
    - Single FireWire 400/800 with limited poer support vs 2 ports each with full power support
    - 2 USB2 ports vs 5 port
    - 2.4x DVD+R DL write speed vs 6x
    - No TOSlink audio
    Shall I go on?

  • Graphic Card Upgrade for HP-Pavilion dv6t-7000

    Hello. I have the HP Pavlilion dv6t-7000 with the NVIDIA GT650M 1GB grpahics card. Now because of my work, i need to extends my graphic card memory. So I want to ask if my laptop is possible to upgrade to GT650M 2GB card.
    My product number is A5F74AV. And my wannary is end on 8/24/2013.
    And this laptop is a gift of my aunt from USA, and I'm living in Viet Nam now. So if yes, can HP Vietnam do the upgrade for me? My aunt's family is very busy so I can't resend my laptop and ask them to return to you.
    Thank you very much!

    Hi:
    The only way to upgrade the video card in your notebook is to replace the entire motherboard which would cost as much as buying a new notebook with better graphics.
    If you had HP do the upgrade, it would probably cost more than buying 2 notebooks with better graphics than yours.

  • Is it possible to upgrade/add a graphics card to a Pavilion dv7-7000 laptop?

    I've been doing a lot of research lately, to mostly no avail, about whether or not my HP Pavilion dv7-7025dx laptop can have a dedicated GPU added to it, as currently it only has the integrated Intel HD 4000 Mobile graphics card.
    Mostly I've come across the unfortunate agreement that most laptops cannot have their graphics cards upgraded/swapped out, since the graphics card is soldered on to the motherboard. However, after talking to an HP "support representative", they said they believed it was possible to add a graphics card, as long as it is compatible with the HM77 45W UMA Motherboard my computer has.
    Furthermore, after finding the maitenence and service manual online for my computer ( http://h10032.www1.hp.com/ctg/Manual/c03221579.pdf ) it says that it could have come with switchable graphics, specifically the Nvidia Geforce 630M or 650M. 
    So I am wondering, is it really at all possible to add a dedicated graphics card, either by having switchable graphics or something else? Or am I stuck with the integrated Intel HD graphics? 
    If I can upgrade/add a new card, where would I be able to find/buy a compatible one, and would I be able to install it myself or would I need to go to a local computer repair?

    Hi,
    You can't add a dedicated graphics card to the system like this. The vga is soldered to the board so no way you can just plug it in like on a desktop. However, you can buy a new motherboard with the dedicated graphics card on it. It also requires a new heat sink. 
    Manual: http://h10032.www1.hp.com/ctg/Manual/c03221579.pdf
    You need a 682040-001 board plus 682061-001 heat sink to have a dedicated graphics card on your laptop. Have a look on ebay for the part numbers.

    I also don't know if the boards come with the windows 8 product key included in the BIOS.
    There may be multiple motherboards listed, so make sure you get the right one.
    Same for the fan and heatsink.

  • How to backup files onto external hard drive if my MacBook's graphics card is broken?

    Hello,
    I have a 15" 2012 Macbook pro with 2gb of ram, i7 processor, and a 250 gb Hard drive. In the middle of using my computer, the screen went black. Upon rebooting the computer, I noticed gray and white horizontal lines running across the screen, but I was still able to see the apple logo and loading indicator in the background. As soon as the login screen appeared, the screen went black again.
    Genius Bar Diagnosis:
    A few days later I took my computer to the apple store to have them diagnose the computer to determine if the hard drive was corrupt or if it was just a display issue. They found that the hard drive was still functioning properly, so no information was lost. The problem was that the graphics card needed to be replaced. So they offered to ship my laptop to an Apple repair facility in Houston, Texas (nearest one to me) and replace the graphics card, as well as any other parts that seemed to be damaged, for a flat rate of about $315. They recommended that I back up my hard drive just in case they found an issue with it (despite nothing showing up in the diagnosis at the genius bar) because the technicians at the repair facility will just swap it out for a new one.
    My dilemma:
    The employee at the genius bar gave me a list of Apple Authorized Service Providers that could help transfer the data from my macbook's hard drive to an external hard drive. I got a quote from them for $150, plus I would have to pay for a new external hard drive because my other one is full. In an effort to save money, I want to see if there is a cheaper way for me to backup the hard drive by myself. I have a pc laptop that still works fine, so I have been using that since my MacBook Pro died on me. Is there any way I could use that other computer to somehow backup my macbook's hard drive? Or would I need another mac to do the transfer? I have looked into buying a hard drive sled, but I don't know how those work, and I may not have all of the right equipment for it. If that is something I have the right tools for, and it's cheaper after buying all the accessories, then I would much rather go that route than taking it in to get serviced at an AASP store. Please help!
    I'll give good ratings to those who give me useful advice.
    Thanks,
