Lenovo G770 CPU & Grafikkarten tausch - CPU & Graphics card replacement

Deutsch:
Hallo, nach dem ich an meinem Lenovo G770 die Festplatte und den Arbeitsspeicher aufgerüstet hab, interessiert es mich ob es möglich wäre den CPU (akutell i5) aufzurüsten?! 1. Falls es möglich wäre nur einen schnelleren i5 oder sogar einen i7? Desweiteren kann man die VGA Karte austauschen? Was für eine wäre da brauchbar als Gamer? Habe ein Buget von ca. 400 Euro für beides, wenn es hoch kommt auch 500. Wäre lieb wenn ihr ein paar tipps hättet welche sachen da gut Leistung rausholen würden. (Grafikkarte ist da weitaus wichtiger als der CPU)

Hello, after I upgraded my Lenovo G770 to the hard disk and memory, it interests me if it would be possible to upgrade the CPU (i5-date)? 1 If it were only possible a faster i5 or even an i7? Furthermore, you can replace the VGA card? What a would be as useful as a gamer? Have a buget of about 400 euros for both, when it comes up too 500 Would love if you had a few tips that things would get out there good performance. (Graphics card is there far more important than the CPU)

  • IMac G5 Graphic Card Replacement for blue screen problem

    When I turn on iMac, I only see blue screen, the apple technician said Need to replace graphic card,  Nvidia Gforce 7600GT 256.
    1, can it install in IMac?  Seem like it work for PC?
    2,  I had blue screen problem several time,  I think I turn on iMac too long, so it burn out graphic card.
    3,  I have 2007 G5 24" screen model,  is any durable and afford graphic card you recommend?
         Where to buy for cheaper price?
         Do I need to change mother board?
    4,  can I replace it by myself?  Any picture or video for graphic card replacement?
    Thank you.

    If you look around, you might be able to find someone who will replace just the chip on the graphics card, which is what usually fails. It will take someone highly skilled; they really have to know what they're doing--it's not an ordinary soldering job.
    Here's someone who found a non-Apple service to do this, and it proved to be far less expensive than a full logic board replacement. But I think this was in the UK.

  • Apple graphic card replacement

    Hi,
    I own mid 2011 iMac 3,4 i7 model with 6790 2GB graphic card which is broken.
    Found Apple replacement program for those cards :
    http://9to5mac.com/2013/08/16/apple-opens-graphics-card-replacement-program-for- some-mid-2011-imacs/
    Can someone tell me is this program available for Europe, (Croatia or Bosnia & Herzegovina) ?
    Best regards,
    Dzenox

    Thanks for replies,
    I found almost  everything what you already mention here but it will be easy if would live in US.
    Europe is also not a big problem, but my country Bosnia&Herzegovina does include some other conditions due to fact that  isn't listed at Apple page of countries.
    We do have some resellers, but I want a clean proof so I can get some benefits from it.
    Btw: it is the second time I have to change graphic card and I dont want to be charged.

  • IMac 2011 graphics card replacement program - service says no to me!

    Hello everyone,
    I have a mac with the exact specifications that are stated here in the graphics card replacement program: iMac (27-inch): AMD Radeon 6970M Video Card Replacement Program
    And the exact symptoms as well. Computer was taken to a service that is approved by Apple, but as I'm in a different country, it's not an Apple store itself. After doing diagnostics for a few weeks, they told me that this does not apply to me. They that the serial number doesn't note that Apple covers anything.
    I have no receipts or anything, had no Apple care either, but this is a replacement statement by Apple and even after having the serial number and seeing that it is the exact model having the exact symptoms - can they still say no to me? What should I do? There are no Apple stores like in other countries and if I took it to one of the official dealer stores, they're just gonna take the computer to the same official service provider. It is really unfair at the moment and I don't know what to do.
    P.s. Should I post my serial number here so maybe someone who works in an official store could help me clear up if it really does not apply?

    I had to have my graphic card replaced.  I was told that I was under the 3 year from date of purchase time limit so got it for free.  How long has it been since you purchased your iMac?

  • Graphics Card Replacement Suggestion

    My current ATI Radeon HD 4350 graphics card fan is making a loud noise and I need a suggestion for a compatible graphics card replacement.  I don't play video games but I do watch streaming videos from HULU, Netflix and YouTube often.  I have a dual monitor setup as well.
    Current PC; HP Pavilion Elite HPE-110f running Window 7.

    Hi:
    I would go with the Radeon HD 6450. 
    Get one of the fanless models listed. Then you have no fan to make noise or conk out on you (such as the ASUS or Sapphire cards listed at the link below).
    http://www.newegg.com/Product/ProductList.aspx?Submit=ENE&N=-1&IsNodeId=1&Description=HD%206450&bop=...
    The card has a maximum power draw of less than 30W and it is the optional card offered on HP business desktops with 240W power supplies.
    Make sure you uninstall your old graphics card and driver in the device manager, shut down and unplug the PC before installing your new video card.

  • CPU & Graphics Card Upgrades

    Hi,
    I do a lot of video and graphics on my Mac Pro 1,1 and would like to upgrade the CPU and graphics cards. I see the CPU may be a trickier install process, but it looks like I'll have no trouble changing out the graphics card. I'll probably just pay someone to do the CPU. But when buying the gear, do you guys have any suggestions that I should keep in mind? Any recommendations for hardware?
    I was looking at something like this for the processor: http://www.newegg.com/Product/Product.aspx?Item=N82E16819115066
    And something like this for the graphics card: hhttp://www.newegg.com/Product/Product.aspx?Item=N82E16814150507
    Any thoughts would be great!

  • Satellite Pro 4600 - CPU graphics card overheat?

    16 days ago my tosh Sat Pro 4600 lost the ability to maintaing 25 fps in an online game - ie. diablo 2.
    It now plays at an average of 4 fps and ping gets up to over 4000... needless to say unplayable now...
    I have reinstalled the game... installed new XP and game on drive D....
    Same thing.... a program called SpeedswitchXP shows CPU usage fluctuating from 54 to 420 because the CPU mhz on the general tab of my computer shows 422 now, not the 847 mhz it used to.
    It still surfs the net and plays yahoo card games eg. at lightning speed but not an online rpg... it has working perfectly at average of 25 fps for 3 years ... Irreparably overheated / damaged CPU ... graphics card ?
    Anyone know? Another temp. program shows it running at 64C worth a new motherboard?
    Can i get one? Any ideas?

    Hi
    First of all you have to know that the CPU and the GPU performances are dynamically.
    This means that the speed and the performance changes if the temperature rises to a critical level.
    This could lead to the worse performance.
    In your case the notebook is about 3 years old and I think its time to clean the ventilators to prevent the notebook from the overheating.
    You could try to use the professional compressed air spray to get rid of the dust and debris.
    Such spays you can purchase from computer dealer.

  • 3D picture CPU/Graphics card compatibility

    I'm debugging some code I'm working on for utilising the 3D picture to display some data.
    I've noticed that certain 3D settings have a large influence on performance as expected but I've also noticed something weird.
    On my work PC (Core i7 2770, 8GB RAM, Win7 64-bit LV 2012 SP1 f5, AMD 3450 Graphics) I have a nice fluid display with several datasets rendering simultaneously.  Zooming and panning is smooth as butter.  On my Home-office PC (AMD X5 1090T (only 4 cores enabled), 8GB RAM, Win7 64-bit LV2012 SP1 f5, Nvidia GTX 460 Graphics) I have way more problems with my display.  This is kind of unusual because the graphics card seems like it should be MUCH faster and Furmark (OpenGL Benchmark) seems to be delivering expected values for my card.
    Are there known combinations of Graphics cards / drivers and/or CPUs with which the 3D picture control work better than others?  I find it hard to understand how my code can run butter smooth on a weak graphics card like the 3450 but has trouble on a much beefier card like the GTX 460.  Using GPUShark utility, I also see that the GPU really is pegged to 100% load even though the workload being requested of it is really small in absolute 3D terms.
    Any experience anyone can share with me?  I've tried installing the latest drivers.  That doesn't help.

    I just tried the same software and the same data on both machines.  Here's a valid comparison of what I'm seeing.
    Computer 1: Intel Core i7 2770, Win7 64-bit 8GB RAM, Win2012SP1 f5, AMD 6350 Graphics
    Computer 2: AMD 1090T, Win7 64-bit 8GB RAM, Win2012SP1 f5, NVidia GTX460 Graphics
    Both computers have all recent patches and drivers installed.  According to any bencahmarks I have found the GTX 460 should be a little over twice as fast as the AMD 6350 card.
    For the same data set of a 1024x1024 profile (displayed as a heightmap) with texture applied (also 1024x1024) plus a small coordinate object (Three arrows in X,Y and Z directions) I see the following.
    Computer 1: Update rate around 17-18 ms (VSync at 60Hz)
    Computer 2: Update rate around 120 ms (Much slower)
    I would have initially assumed that Computer 2 is NOT using the 3D capabilities of the graphics card.  I checked OpenGL functionality by running Furmark and the results for my card match what a GTX 460 should deliver.  While the LV software is running GPUChark shows that the GPU is running at 100%, so something IS running on the graphics card but it seems to be horribly inefficient.
    At ths stage, while I love the functionality of the 3D picture, the not-quite-understandable differences seen between PCs has me worried.  I don't want to propose changing out display routines from 2D to 3D and have the overall update speed deteriorate.
    I know there was a change made to the 3D picture a while back because it didn't work well with AMD graphics.  I now have the opposite problem.  The same behaviour was observed in a vanilla 2012 SP1 installation (without any patches, f0 so to speak) so I don't think it's a side-effect of the AMD patch.

  • Is it possible for my 2011 Macbook Pro i5 intel HD 3000 to have its Graphics card replaced?

    I am trying to figure out if I can upgrade my graphics card. In the future I would like to install Windows 7 using bootcamp and play multiplayer games such as Modern warfare 3.

    If I upgraded those, is it possible that I will be able to play multiplayer games i.e. MW3 at 30 fps or higher?

  • Graphics Card Replacement Help

    Greetings - A trip to the Genius Bar has confirmed that I have a bad graphics card (ATI Radeon 9600) in my PowerPC G5. It's working again for the time being, but needs to be replaced. The Apple Genius I worked with assured me that I could purchase and replace the card on my own (yikes but I'm willing to give it a go), but that particular card does not seem to be available and I want to be sure to use a suitable replacement. I've read through quite a few of the posts related to this topic, but as I am totally new to all of this, much of the discussion is beyond me.
    I'm wondering about the "NVIDIA GeForce 6200 Mac 256MB G5 AGP video card VGA+DVI" recommended by Makman8688 in the recent "Graphics Card Update" post. I do a lot of Photoshop work and hope to move into video at some point. Would this card be a suitable replacement?
    Many thanks for any guidance.

    Hi-
    As explained there are 2x, 4x and 8x AGP cards. This is the bus speed multiplier.
    The G5 uses the fastest AGP bus, that of the 8x AGP bus.
    You mention DVI ports. If you have a requirement for two DVI ports, your card choices then become limited to cards with two DVI ports, or to OEM cards with ADC and DVI ports.
    ADC ports can use a simple adapter to make them DVI compatible.
    For video work, any card faster than a Radeon 9800 Pro should be considered.
    A relatively common, and very nice graphics card is the Geforce 6800 Ultra. This card has 2 DVI ports and the power to run HD resolutions.
    It does, however, cost $200-$280.
    If you don't need two DVI ports, then the Geforce 6200 card is an option, but not necessarily a power house type of card.
    It is a bit better than the 9600, however, with a used 9650 being an option as well.
    A Radeon 9800 Pro or XT will be quite a bit faster than the 9600, but are both limited to 1 DVI port.
    These cards are better for video than the 6200 or the 9600.
    The Pro sells for from around $95 up to $185, with the XT selling for $120-$190.

  • 1st Gen Mac Pro Graphics Card replacement??

    I have a 1st generation mac pro and the nvidia geforce 7300 GT graphics card died.
    what can I replace this with that is relatively inexpensive? Does it need to be 256 or 512 MB?

    Thank You. That isn't quite my situation. There is a back on April 11th. 2010 and still unsolved. That is very disappointing considering there are a lot of people who are genius with technical issues on this forum.
    It booted up OK from a long power down time but if I have to restart for any reason or power down and start up within a few minutes, I will have nothing on the display (black). The little light is on and if you touch the button the light will goes to sleep but nothing on the display. I checked everything and tried every combinations. What I ended up with is; 1. to leave the computer on forever until the end of time but I can't because sometimes the fan would come on high and stay on., 2. if I have to restart, I have to unplug both power chords and wait at least half an hour to forty five minutes then plug everything back in and start. Most of the time it will work. This puzzled me.
    Everywhere I posted this problem, I've had zero answer. There must be some one who knows this issue and solved it before. Hello! Are you out there? Help me please!

  • Graphics Card Replacement - Dual 2.7 Early 2005 - Which?

    Hi all,
    I feel bad for posting a new topic, as japamac and other users have addressed this question before, however, I'm confused!
    My used Dual 2.7 Early 2005 G5 has the stock graphics card in it at the moment, as the 800XT that my dad had been using in it broke while he was doing some maintenance prior to giving it to me.
    I want to replace the graphics card because:
    -I like to stream videos, and it doesn't do it as well as I'd like.
    -I play a lot of Civilization 4: BTS, and want to turn my graphics setting up w/o trashing performance.
    -I want to edit RAW photos in Aperture (will upgrade to 3 soon) with shorter load times.
    So which card would you recommend? I've been confused, as I believe the graphics slot is PCI-X (not express, I've got that one down), but a lot of the cards discussed in archival threads are 8x AGP. Perhaps the computer has both slots and I'm unaware? I feel further hampered by my lack of knowledge when the best source for this upgrade may/will be ebay.
    Your advice is very much appreciated.
    Gorf

    Hi-
    Your machine is 8x AGP graphics and accepts one 8x AGP compatible graphics card.
    The other expansion slots are either PCI or PCI-X.
    You are looking for a Mac compatible graphics card, with a minimum of a Radeon 9800 XT 256MB card needed for your uses.
    A Geforce 6800 GT or Ultra would be better yet, and of course, the Mac X800XT is also a good candidate.

Maybe you are looking for
