Successful T61P Nvidia GPU motherboard swap to T61 Intel GPU

Hi all,
Just finished my first successful T61 Intel GPU motherboard conversion from a failed T61P with the dreaded "fatal" Nvidia GPU disease. At a very reasonable price, forum contributor Tuus furnished me with a good used T61 Merom/Intel board with a Middleton bios, which allows for faster Penryn CPU's (up to T9500) and SATA2 speeds on a Merom/Intel motherboard. I used the on-line Lenovo training videos and the Lenovo system maintenance manuals as a guide, and all went quite well. Thanks to all previous forum posters for providing me with an incredible knowledgebase of Thinkpad laptop system problems and solutions, and in particular TuuS for sharing his upgrade recommendations and repair experience.
T61P- 15.4 WSXGA, Intel 965 GPU, 4GB mem, T9300 CPU, 100gbx7200 rpm HD

Happy to hear that the planar swap went well.
Enjoy your reborn T61!
Cheers,
George

MBP 2010 Intel GPU graphics glitches.

I've noticed that occasionally when my new Macbook Pro switches from the nVidia discrete GPU back to the integrated Intel GPU (tracked by the gfxCardStatus app), the LCD display becomes corrupted, I could best describe it as "sparkly" pixels in visible bands, and occasional wobbling of pixels.
I'm unable to take a screenshot with Grab, which leads me to believe this is a problem between the GPU and the display itself, not with the memory or GPU.

I am (and a few others are, too, it would seem) having the same issue. The integrated GPU corrupts everything, but the nVidia works great. The one problem is I run on battery the majority of the time, so I need to maximize my battery life.
I've been switching between the two by unchecking the "automatic graphics switching" option under "Energy Saver" in the preferences. If it's unchecked, you automatically use nVidia. Otherwise your computer will switch to the integrated GPU whenever it's not doing anything graphics intensive
Edit:
Also, mine seems to have begun occurring after the most recent software update that was offered.

Official 2009 Lenovo T61/T61p Nvidia Video Drivers: Please Consider One Last Update for the Road

The title of this new thread says it all ..... 3 years since the last offical Lenovo T61/T61p Nvidia Video Driver Package release ..... a virtual lifetime in computer science years.
I'm looking for advice on how to best lobby the technical folks at Lenovo (by phone or here on the Forums) for one last official Lenovo "Nvidia" video driver update for our T61 and T61p units.
Lenovo's most current "ancient" 2009 Nvidia driver packages (found here),
http://support.lenovo.com/en_US/downloads/detail.page?DocID=DS001342
http://support.lenovo.com/en_US/downloads/detail.page?DocID=DS003876
http://support.lenovo.com/en_US/downloads/detail.page?DocID=DS003605
all leave quite a bit of 3D (and some 2D) performance laying out there on the table based on my own testing with current modern Nvidia reference drivers on a cloned test mule hard drive (and never once crashed with the newer Nvidia reference drivers under WinXP 32-bit or Win7 32 bit).
Most all the major 3D gaming benchmarks were nearly doubled, and most importantly, my real world qualitative performance experience seemed even greater than the nearly doubled quantitative benchmark results.
I'm wondering if starting this new thread would be of any benefit to encourage the good folks at Lenovo to consider one last update after 3+ years?
Before I go to the trouble of posting my results, it is my hope that Lenovo could simply try the latest Nvidia reference drivers for themselves, tweak them (if even necessary) and then issue one last offical T61/T61p Nivida driver package update for the road .... hundreds of thousands, if not millions, of T61/T61p w/Nvidia GPU units are still in reliable daily service.
http://www.geforce.com/drivers
Something to please consider.
Two (I used to have Five) - T61p 15.4" WS T9300 2.5Ghz units, August 08/08 Builds with FX570M Nvidia Graphics; ... One W520 i7-2860QM w/2000M Nvidia Graphics (most recent acquisition and stupidly fast); .... One - T42 4:3 15" Flexview 1.8GHz with ATI Graphics (still perfect for traveling); ... Two - T500 15.4" units both with ATI HD3650 Graphics.

Hi eecon
It is considered fortunate that Lenovo provides newer driver for newer OS even after the system was phased out. From what I know, most of the OEM / manufacturers do not provide drivers for newer version of Windows when the product is phased out.
Furthermore, graphic card vendors (e.g. NVIDIA, Intel, AMD, etc.) oftenly release new drivers and it is hard for manufacturers to catch up with them. Usually, the purpose of OEM providing new driver is to resolve existing issues. If you need performance, get newer drivers directly from vendors website.
Have a nice day!

T61 - dying Intel GPU?

Hello all, this is probably my last chance to understand what's happening to my beloved T61. Here the specs:14.1" model - 1440x900px2.4 GHz T7700, undervolted with RightMark CPU Clock Utility5 Gb Ram250 Gb SSD (Middleton BIOS) + 250 Gb HDD in superbayIntel 965 chipsetIntel X3100 graphics chipWin 7 64bitBought used in 2011 and almost completely refurbished it. I think it's from 2007 or so.Plus, LOADS of love So, the problem I'm experiencing with the display can be seen in the attached pictures. The problem is not constant but comes and goes, (but now it's like this almost all the time), apparently in a random way, although once I noted that it is more likely to appear when there is a lot of white on the screen. It looks like pixels of a certain colour are turning red, for example, if I watch a movie, the black bars are all red. It's for sure not a screen problem, but graphics artefacts. I know what a tinted flourescent tube looks like as I have already replaced the screen on this laptop. The analogue VGA out works correctly. Installed different versions of the driver several times. In the beginning this seemed to solve the problem, but now that doesn't help anymore. Is the GPU about to die? if that happens, will I be able to still use the VGA out or will I have to replace the motherboard? Thanks for helping out!

.think about buying another one...preferably with Quadro GPUs! I'd have to disagree here. If the intel GPU did actually die it's the first I'm aware of ever dying, but the nVidia were plagued with failures, but in any case there was a recent cache of brand new motherboards for this model found, the latest revision with support for Penryn processors and I think there are a couple left. If you'd like one you can send me a PM and I'll confirm it's still available. Looking at the first photo I must admit it looks like a failing backlight, but I agree with the other opinions here that if the external vga adapter displays the same the cause must be the motherboard. As for ram being the cause, I think if your ram was failing to this degree you'd have noticed stability issues too and constant blue screen crashes. most ram problems can be confirmed by removing one module at a time to identify the bad one.

T61p nvidia driver

So I upgraded to windows 7 and now i have to find the driver for my video card.
I have an Nvidea Quadro 570m card and i went on nvidea's website but none of them were listed and also I need this because I run a dual screen on my laptop.
Solved!

Why my NVIDIA GeForce GTX 780M does not support GPU in After Effects

I use Adobe After Effects. How do I get the video card enable GPU?

Although this card is not specifically mentioned in the hardware spec for After Effects this does not mean it wont be able to use GPU graphics rendering.
See the the adobe GPU information page for more details: GPU Features in After Effects

Nvidia to put more force behind Intel processors

Nvidia, a maker of graphics chips, on Friday announced plans to create a version of its nForce chipset for Intel processor PCs. That's something Nvidia couldn't legally do in the past but can do now, thanks to a broad patent swap with Intel.
A chipset is a PC's nervous system; it stewards data as it travels through the machine.
The patent swap will help give the chipmaker access to a broader swath of the chipset market. Nvidia--along with ATI Technologies, its rival in the market for graphics chips--entered the PC chipset business several years ago in an effort to remain competitive as desktop and notebook PC makers moved to so-called integrated graphics chipsets, which incorporate graphics processors.
"Our view is that it'll give our customers another choice...and a choice from a company with a very good reputation."
--Chuck Mulloy,
Intel spokesmanDespite Advanced Micro Devices' efforts to encourage companies to build chipsets for its processors, Intel still dominates the PC processor space, with around 82 percent market share.
Intel's large processor share, in turn, bootstraps shipments of other companies' chipsets, making it important for manufacturers such as Nvidia to offer chipsets for both Intel and AMD processors.
But despite the fact that its nForce chipset has been popular among owners of AMD PCs, Nvidia wasn't able to build a version of the chipset for Intel processors until now because it lacked a license for Intel's front-side bus, the pathway for shuttling data back and forth to the processor.
The agreement between the two chipmakers--which spans years, product lines and product generations, the companies said in a statement--also grants Nvidia a multiyear license to the Intel bus, paving the way for an nForce for the latest Pentiums.
Nvidia didn't announce details on when it might begin offering nForce chipsets or which types of PCs the sets would fit. However, when the company does start offering them, it will face stiff competition from Intel--which makes chipsets and motherboards for its own processors--as well as from several other chipset manufacturers. ATI, Nvidia's chief graphics rival, along with Acer Labs, SiS and VIA Technologies, all have agreements with Intel to build chipsets for PCs based on its chips, and thus offer numerous chipsets for Pentium processor PCs.
Intel still enjoys a lion's share of the chipset market and lately has begun viewing chipsets as a much more important part of its business, as it can use them to add new features to PCs and thus boost processors sales. It also aims to make its chips more attractive by bundling them with new elements, such as wireless modules. Centrino, its chip bundle for wireless notebooks, is one such example.
However, Nvidia and other chipset makers have an audience in submarkets, including smaller PC manufacturers and enthusiasts who build their own PCs.
Yet Intel's licensees have proved more aggressive than the chip-making giant, adding new technology more quickly (which has helped them gain the loyalty of enthusiasts) and building speedier graphics into their chipsets. Thus they have able to carve out niches in the business. ATI's Radeon IGP chipset, for example, has been used in numerous notebook PCs.
Still, Intel, which once protected its bus technology much more closely, leading it into legal battles with Via Technologies, regards its agreement with Nvidia as a positive for its customers.
"Our view is that it'll give our customers another choice...and a choice from a company with a very good reputation," said Intel spokesman Chuck Mulloy.
Financial terms of the agreement were not disclosed.

Quote
I just hope Nvidia doesnt loose focus and work harder for the Intel community, as there biggest thing is graphics chip sets and AMD is the better CPU when it comes to games.
1) How can a company make chipsets for 2 different companies without making one better than the other?
2) How can they guarantee that they will not be biased to one platform?
I believe this was a desperate move form Intel because of the announcements from DELL using AMD processors.
Nvidia stated a long time ago that they weren't making chipsets for Intel because they'll have to pay royalties to them.
Edyros!

FAQ: What features use the GPU and how do I troubleshoot GPU issues?

Photoshop CS6 GPU FAQ
Introduction
This document provides a quick reference guide to video card usage in Photoshop. Some features require a compatible video card to work; if the video card or its driver is defective or unsupported, those features will not work at all. Other features use the video card for acceleration and if the card or driver is defective those features will run more slowly.
Mercury Graphics Engine
The Mercury Graphics Engine (MGE) represents features that use video card, or GPU, acceleration. In Photoshop CS6, this new engine delivers near-instant results when editing with key tools such as Liquify, Warp, Lighting Effects and the Oil Paint filter. The new MGE delivers unprecedented responsiveness for a fluid feel as you work.
MGE is new to Photoshop CS6, and uses both the OpenGL and OpenCL frameworks. It does not use the proprietary CUDA framework from nVidia.
In order to use MGE, you must have a supported video card and updated driver. If you do not have a supported card, performance will be degraded. In most cases the acceleration is lost and the feature runs in the normal CPU mode. However, there are some features that will not work without a supported video card.
GPU features added in Photoshop CS6
Adaptive Wide Angle Filter (compatible video card required)
Liquify (accelerated by compatible video card with 512MB VRAM, GPU mode unavailable on Windows XP)
Oil Paint (compatible video card required)
Warp and Puppet Warp (accelerated by compatible video card, GPU mode unavailable on Windows XP)
Field Blur, Iris Blur, and Tilt/Shift (accelerated by compatible video
card supporting OpenCL, GPU mode unavailable on Windows XP)
Lighting Effects Gallery (compatible video card required with 512MB

GPU/OpenGL preferences in Photoshop CS6
The advantages of using a compatible video card (GPU) with Photoshop are that you can experience better performance and more features. Problems can occur if you have an older video card with limited VRAM or if you use other programs at the same time as Photoshop that use the GPU.
Choose Edit > Preferences (Windows) or Photoshop > Preferences (Mac OS).
In the Performance panel, make sure Use Graphics Processor is selected in GPU Settings.
Click Advanced Settings and specify the following options:
Mode > Basic
Mode > Normal
Mode > Advanced Provides the benefits of Normal mode as well as newer OpenGL advances that can result in improved performance.
Use Graphics Processor to Accelerate Computation
Use OpenCL Uses the GPU to accelerate the new blur filters (Field Blur, Iris Blur, and Tilt-Shift) – OpenCL will only be available on newer GPUs that support OpenCL v1.1 or higher
Anti-Alias Guides And Paths Allows the GPU hardware to smooth the edges of drawn guides and paths.
30 Bit Display (Windows only) Allows Photoshop to display 30 bit data directly to screen on video cards that support it
Quick GPU Troubleshooting Steps
You can experience problems such as artifacts, errors, and crashes if there are incompatibilities between Photoshop and the display components that access the GPU.
If you experience crashes, incorrectly rendered windows or objects, redraw issues, or performance issues while running Photoshop, first determine whether OpenGL is causing the problem.
Turn off OpenGL.
Choose Edit > Preferences (Windows) or Photoshop > Preferences (Mac OS).
In the Performance panel, uncheck Use Graphics Processor. Click OK.
Restart Photoshop, and perform the same function.
If the problem recurs while OpenGL Drawing is disabled, OpenGL is not the cause. For additional troubleshooting, see Troubleshoot system errors and freezes | Adobe software on Windows (cpsid_82252) or Troubleshoot system errors and freezes | Adobe software on Mac OS 10.x (cpsid_82414).
If the problem resolves, proceed with the rest of the troubleshooting steps to fix OpenGL.
Make sure that you're using the latest update of Photoshop.Updates fix bugs and issues.
Update the display driver.Updated display drivers can fix many issues, such as crashing, incorrectly rendered objects, and performance problems. Determine what video card you have and go directly to the manufacturer's website (nVidia or ATI/AMD) and download the latest driver. (Note: Simply doing a Windows Update is does not guarantee you are using the latest driver. You must go directly to the nVideo or ATI/AMD websites to get the absolute latest driver.) After you update your driver, turn on Use Graphics Processor in Photoshop preferences.
Reset preferences.
Resetting preferences returns OpenGL settings to their default status. Reset Photoshop preferences by pressing and holding Shift+Ctrl+Alt (Windows) or Shift+Option+Command (Mac OS) immediately after you start Photoshop.
Click Yes when asked if you want to delete the Adobe Photoshop Settings File.
Retry the function that caused the problem.
Change the OpenGL mode to Basic.
Setting the OpenGL mode to Basic uses the least amount of GPU memory and the most basic GPU feature set.
Close all documents.
Choose Edit > Preferences (Windows) or Photoshop > Preferences (Mac OS)
In the Performance panel, click the GPU Settings Advanced Settings button.
Choose Mode > Basic
Restart Photoshop.
If this solution resolves the problem, switch to Normal mode. See if the issue recurs. If the issue recurs, return to Basic mode.
Note: If you’re changing GPU preferences to troubleshoot a problem, re-launch Photoshop after each change.
If you are using more than one video adapter, remove the additional cards.
Multiple video adapters can cause problems with GPU accelerated or enabled features in Photoshop. It's best to connect two (or more) monitors into one video adapter. If you have to use more than one video adapter, make sure that they are the same make and model. Otherwise, crashes and other problems can occur in Photoshop.
Note: Using two video adapters does not enhance Photoshop's performance.
Check your Cache Levels setting.
If you've set your Cache Levels to 1 in Photoshop preferences, you can experience performance issues with GPU features. Reset Cache Levels to the default setting, which is 4.
Choose Edit > Preferences > Performance (Windows) or Photoshop > Preferences (Mac OS)
In the Performance panel, choose Cache Levels > 4.
The GPU Sniffer
To help guard against Photoshop crashes related to bad GPU hardware or drivers, Photoshop employs a small program called the GPU Sniffer. Every time Photoshop is launched, Photoshop launches the sniffer. The sniffer runs rudimentary tests of the GPU and reports the results to Photoshop. If the sniffer crashes or reports a failure status to Photoshop, Photoshop will not use the GPU. The Use Graphics Hardware checkbox in the Performance panel of the Preferences will be unchecked and disabled.
The first time the sniffer fails, Photoshop will display a dialog indicating that it has detected a problem with the GPU. On subsequent launches the dialog will not appear unless the Photoshop preferences are reset.
If the user corrects the problem, either by replacing the video card or by updating the driver, then the sniffer will pass on the next launch and the Use Graphics Hardware checkbox will be enabled and returned to its previous state (enabled or disabled).
Tested video cards for Photoshop CS6
Adobe tested the following video cards before the release of Photoshop CS6. This document lists the video card by series. While the minimum amount of VRAM supported on video cards for Photoshop CS6 is 256MB, some features require 512MB of VRAM to be enabled.
Note: Adobe tested laptop and desktop versions of the following cards. Be sure to download the latest driver for your specific model. (Laptop and desktop versions have slightly different names.)
nVidia GeForce 8000, 9000, 100, 200, 300, 400, 500 series
nVidia Quadro 400, 600, 2000, 4000 (Mac & Win), CX, 5000, 6000
AMD/ATI Radeon 2000, 3000, 4000, 5000, 6000, 7000 series
AMD/ATI FirePro 3800, 4800, 5800, 7800, 8800, 9800, 3900, 4900, 5900, 7900
Intel Intel HD Graphics, Intel HD Graphics P3000, Intel HD Graphics P4000
Note: ATI X1000 series and nVidia 7000 series cards are no longer being tested and are not officially supported in CS6 – some basic GL functionality may be available for both these cards.
Note: 3Dand some Open GL features are disabled on Windows XP, as stated on : http://labs.adobe.com/technologies/photoshopcs6/

I've had several timeout since the pings were started. Got a some response times > 1ms (nothing greater than 7 or 8ms), but no timeouts.

Primusrun has overhead in copying frames from the virtual display to the actual display. You have a very low end Nvidia card and this overhead decimates performance so much the whole thing ends up slower than using the Intel GPU which has no such overhead. Primusrun is still basically a hack, not a proper Optimus solution.
It's also possible that because glxspheres is so simple, this overhead plays a much bigger role than with something more demanding of the GPU. Try a proper demo or an actual game, you might see a different picture then.

Photoshop CC only detects Intel GPU instead of AMD Radeon (Win8)

Hi,
I am running a pc with Win 8 and Intel i7-3630QM CPU.
On my system I am running 2 Video Cards, both Intel HD Graphics 4000 and AMD Radeon HD 7670M.
I set my switchable cards to high performance when using photoshop.exe, but when I check in PS Preferences, the detected Graphic Processor is Intel HD 4000.
How can I set my AMD radeon for higher performances?
Thanks
Cecilia

With dual-GPU's, it is often necessary to disable the Intel GPU, usually in the computer's BIOS.
Many laptops have dual GPU's, to allow them to run with low power consumption (on the Intel), and then they automatically switch to the AMD/ATI, or nVidia GPU, depending on which chip is installed, for more graphically intensive work. That often works well, but not in all cases. In most of those anomaly instances, the switching in the BIOS takes care of the issue - inconvenient? Yes, but often necessary. Some users have had good results by disabling the Intel in the OS's Control Panel, rather than at the hardware level with the BIOS.
Good luck,
Hunt

Intel gpu graphic card dose over heat ?

i have a really bad experience with hp pavilion Dv6, i have many problems with GPU and overheating in the end the GPU corrupted and now i have to buy and replace new motherboard but the only mother board available now is the one with INTEL Graphic card not ATI , my question is if i replace the motherboard, does i going to suffer from the overheating problem again ?? is it better to replace my motherboard with the one that has intel GPU since that may reduce the overall temperature ??
note: my laptop is out off warranty.

The Intel integrated video will definitely run cooler than the ATI video model. The graphics performance will be quite a bit lower, but the Intel is good enough for anything except gaming and CAD and other intense graphics stuff.

GS70-2PE - All video outputs are on damn intel gpu. :((((

Is there any chance to disable intel GPU? My friend takes 4k@60hz output over a simple HDMI cable with his ASUS N56vz computer. Because HDMI port is on the nvidia gpu. But with this very expensive computer I can only see 3 options in the nvidia control panel. I cant even see stereoscopic 3d options. Do you have any suggestion? Can I take hdmi output through nvidia GPU?

Horrible.... Like nightmare...
if you want a laptop to fully use Nvidia then try finding a dual gpu laptop like Y510P from lenovo that has GT750M SLI which disables intel gpu and puts 1 of them as main gpu and other 1 as sli gpu or you can maybe go for Nvidia GT80 that has 2 gpu's if i understood so then it should act like Y510P from lenovo to be nvidia as main only and not using optimus switch.

Disabling Intel GPU in the Z68MA-ED55

From what I have seen so far in the BIOS (v10.3), there seems to be no way to completely deactivate the Intel GPU on my i5-2500 with this motherboard. Am I missing something here, is this feature perhaps planned in a future BIOS release, or is this type of functionality impossible under the z68 chipset?

I'm hoping a firmware developer can chime in here and provide some clarification on this
That may be a possibility. Perhaps you want to open a ticket with MSI technical and pose that question. >>How to contact MSI.<<
