GPU? Graphics drivers? Question for Penryn MBP owners.

I have a Penryn 2.4 MBP (current generation) and, after one graphics update and several os upgrades, I am still experiencing bad graphics.
Some times, very rarely, I still have corrupted text. It is self-healing, after a while it goes away. If I try and take a screenshot of the window with corrupted text, the screenshot is ok.
I have still flickering and big, white boxes in on-line videos, like the ones on youtube. Even in this case the problem appears to be self-healing. It goes away after a while and I do not think that it is heat-related, sometimes it happens when the components are not very hot.
Scrolling sometimes is bad. For example, in single-column Finder window, sometimes I cannot see the 1/3 bottom part of the column, which appears empty, when I scroll.
Frankly all these problems are absurd and I started thinking that they are hw-related. It's impossible apple is not able to offer stable and good graphics drivers/subsystem. Anyway, I have no problems when using non-apple applications, like firefox (but in Firefox I still see big white boxes in videos).
What is your experience?

This may be an old post, but for those still looking for an answer you can get the 13.12 (December 2013) AMD graphics driver from https://www.dropbox.com/sh/915fpdtgbgoksct/kOY7bKHgKq Select "Download->Download as .zip".
I only modded the driver for the windows 7 64-bit install, so if you using windows 8 under bootcamp you'll have to follow the included instructions yourself.
Please let me know/like this post if this works for you. (It would be great if you could report whether it worked based on using Win 7 or Win 8)

Question for S10-3t owners

Hi Folks,
I'm seriously considering purchasing an S10-3t, but I have a question for you.
Is there a reason everyone is choosing the low-end model?
I'm looking at the one with 2 GB, faster processor, larger hard drive, Windows 7HP, Bluetooth.
I've priced it out and it is about $110 more than the best price I've seen for the low end model ($399). It seems like the price difference is probably worth it.
Note: I am pricing it out with and additional 8 cell battery to go with the 4 cell it comes with, and there is currently a 15% off promotion until June 3
Faster processor: $10?
Extra memory: $30
Windows 7 HP upgrade: $80 (according to Microsoft)
Bluetooth: $15-30+ (Seems really handy for 3G tethering and/or external peripherals)
Anyone else have any thoughts on this?
Thanks!

The following is from a post I put on the forum on March 17.   The prices shown is what the models cost at that time.
I originally bouth the S10-3T with the N450 chip and 8 cell battery from a retail store in US. I returned the unit to the store and opted for the S10-3T with N470 chip and 4 cell battery. Lenovo includes Windows Home Premium and Bluetooth.
I bought the 8 cell battery as I was not sure which I would prefer. The 4 cell battery is nice because its flush with unit. Its good for me during my daily commute. The 8 cell battery is definitely needed for long trips. The 8 cell sticks out and is personal choice if you like the added bulkiness.
Prior to returning the N450 model, I recorded the Windows Indexing results and ran Geekbench. For those deciding which model to purchase below is a benchmark and average price comparison of both machines.

Graphics card question for Remotefx

Hello, I would like to run anywhere from 24-30 vms in hyper-v with remotefx.
I read somewhere there was a gpu limitation with remotefx for up to 12 vms per graphics card while using remotefx.
Is this true? If I wanted to run 24-30 vms in hyper-v I would need at least 2 graphics cards?
Any help is much appreciated
Also is there anyone out there who had success using a r9 280x or gtx 770 graphics card for remotefx? I'm trying to decide which of these two to buy

It's hard to imagine I'd be the first or one of many, much time has passed since I've found all of these different individuals who have since created these posts/blogs/youtubevlogs with casual googling:
In all of these examples you will read or watch different indivuduals use consumer grade graphics cards with remotefx:
http://2008release2en.blogspot.com/2011/04/remotefx-gef... -
gtx 465
http://www.itinthedatacenter.com/wordpress/?p=267 -
gtx 650
http://blogs.msdn.com/b/virtual_pc_guy/archive/2011/01/... -
gtx 480 (this guy even talks about playing games with it such as Fallout 3, Blur, Torchlight, Civilization V, Batman: Arkham Asylum and Street Fighter IV)
Here is a video of someone on youtube playing halo 2 with his older consumer graphics card with remotefx:https://www.youtube.com/watch?v=CYiLGxfZRTA
All of these are using really old graphics cards, I was really hoping there were more recent consumer grade graphics cards known to work with remotefx. I feel as if I were to just go buy a gtx 770 4gb it should work like all the older gtx models, but
it would sure be a pita for it not to work and have to return it and pay shipping and handling and the restocking fee only to go and buy another card and repeat this process until I find something that works
Which is why I'm asking on the forum, surely I can't be the only one interested in this
Also in terms of SLI and how well consumer grade graphics cards work, I read somewhere (trying to find the post) that someone was using 2 gtx 465 (2gb each card) sli to run about 30 vms with 125 vram to each host and 1.25 ram and a dual processor. I'm
desperately trying to find the post because I'm not exactly sure which card it was, gtx 465 or gtx 450. All I know was it was a consumer grade gtx 400 series card and it has 2gb vram each card. All vms were playing games on the lowest possible
settings etc

Question for C6-01 owners

Hello. I just received shipment of a C6-01 from Nokia. I like it... build feels good, it seems as good as all the Nokia phones I've had before. But I have a question for those who have the C6-01. When you look at the camera on the back of the phone, is the LED flash mounted at a slightly different angle than the camera lens? On this new phone it looks like the flash is on slightly different plane. If you would look at your phone and tell me if this is consistent I would appreciate it... I want to make sure this one's not damaged.

Hard to show in pic... hopefully you'll get the idea.

Display Questions for Current T410s Owners

Hello all,
I am in the market for a new laptop and I have boiled it down to the T410s. There is only one issue that concerns me about the actual laptop, the max resolution size. Currently I am using a 15 incher @ 1920x1200 which gives me lots of screen real estate. I do not find the text at all hard to read and I know that it would be presumably smaller even at 1080p on a 14 inch screen which probably wouldn't bother me either.
My questions to the board are:
Has anyone been in the same boat and actually bought a T410s? Do you miss all of the screen space that you used to have or did you just get over it?
Also has anyone successfully replaced the screen with a higher resolution option? Even a 1650x1050 wouldn't be a bad option. This could include unofficially supported screens among other things. Basically, just wondering if a screen change out would work.
Thanks!

I don't think a 1680x1050 screen panel exists for the 14.1" size.

Question for Mac Pro owners w/Pioneer DVR-112D superdrive: what firmware?

For those whose Mac Pro came pre-installed with the Pioneer DVR-112D superdrive, what firmware revision is it running?
The reason I'm asking is that I have an aftermarket 112D, bought from OWC, that I purchased for it's rip/burn speed advantage over the pokey, possibly riplock crippled, Sony DW-150A that came with my Mac Pro. This advantage was indeed gained, but at the expense of living with some quirkiness with the drive, namely the "two-ejects required" problem discussed here:
http://forums.macrumors.com/showthre...highlight=112D
This quirkiness has gotten worse since the latest Mac Pro EFI firmware update on 09/27/07. Now if I'm watching a movie from a DVD in the 112D tray, any extended pause (and by extended I only mean more than a minute or so) causes an unrecoverable error in DVD Player and I'm forced to restart the DVD Player and restart the movie.
My suspicion is that this all has something to do with some (overzealous?) power management feature in Mac OS X that's not playing nice with the existing 112D firmware (I'd be interested in hearing any other plausible theories).
Currently, my 112D firmware is at revision 1.06. There a number of updated firmware revisions for the 112D circulating on the internet, PC centric, of course and mostly related to disabling region-locking etc.
I'd like to match my 112D firmware to whatever Mac Pro owners with a 'bona-fide' 112D enjoy, if it's publicly available somewhere.
Thanks.

The latest Pioneer DVR-112D/212D OEM firmware is v. 1.22 dated august 7, 2007. My general practice is to Avoid Apple firmware on OEM drives, it often disables features and is most infrequently updated.
My 112D is at version 1.21. Over the years I have successfully updated the firmware in my Pioneers using the Terminal app DVRFlash. But DVRFlash doesn't support the 112 or 111 series (yet). I wondered how you had updated to 1.22. I know it can be done by connecting to a PC, (which includes Bootcamp, but not Parallels) but I don't have ready access to a PC. At the moment I am waiting for Leopard before going Bootcamp way.
Any advice?
Hope this isn't hijacking the thread.

Windows 8 Clean Install drivers question for USB, CD, and Wifi

Hello,
I did a clean install using bootcamp for Windows 8. The problem I am experiencing is that I cannot download the needed drivers through bootcamp due to a slow connection. (I am in Afghanistan for work). Does anyone know where I can get the drivers so my USB ports, Cd-ROM drive, and Wifi will work from an external website where I can use a download manager? I have a 15' Macbook Pro-Mid-2012.
Thank you,
Ryan

Power Supply and Graphics Card Question for HP Pavilion a6432p

Hello!
I have the HP Pavilion a6342p, and I'm wanting to install an NVIDIA Graphics Card either 512MB or 1GB. However, I'm not sure what is the power supply to this model (most graphics cards are saying 300-350W supply required).
Can anyone tell me what is the power supply to this model, and what would be a good graphics card model to look at to upgrade my graphics card to with this model? I believe the expansion slots are PCI-Express, but I'm not sure on the power supply so I can get the right graphics card.
Thanks!
Nathan

No the 9100 is not just an integrated video chipset and is available in both AGP & PCI form.
The Antec is a good PSU but I would recommend getting something better such as the OCZ or Enermax as they have a higher +12v rail amp.

Interesting question for original iPhone owners

Hi,
I was looking at the back of my device today while it was out of the case (more then usual) and when looking at the two lines of text (below the word "iPhone" but above the memory size icon...in my case mine says "8GB" with a square around it, if you look at the two lines really closely it looks like the lines of text are not straight (more on the right part of the two lines verses the left part of the two lines.
When I turn the phone sideways looking at the text, then it pretty much looks aligned. I'm wondering if what I'm seeing is just an optical illusion when looking at it right side up or are the two lines really not imprinted on the device in a straight line?
Intersted to hear other owners in their findings. It's kinda bugging me now so I wanted to ask other people if they see the same thing as I do.

Are you referring to the second line, beginning roughly with the IMEI number? Using a Schaedler Precision rule, magnification glasses, and a lot of squinting under a halogen lamp, it appears the capital letter height of IMEI is approx. 1/64th of an inch taller than the capital letters ~ FCC ID ~ on the far left of that line. 1/64th is the smallest unit on this ruler. The IMEI on my phone is aligned on the upper portions of the FCC letters, but not along the IMEI baseline of that second line. It's optically insignificant to me, especially since it's on the back and in a case. Hope this helps.

DPS Question for Master Collection Owners

I own the Master Collection and am not interested in subscribing to the Creative Cloud at this time.
My educational institution has a much easier time fiscally in one-time outlays (licenses) rather than monthly (continuing) subscription models.
For this reason I am interested in DPS however not in the Creative Cloud.
I have been having a bear of a time finding out any information regarding non-Creative Cloud DPS pricing.
I sense a real push from Adobe to the Creative Cloud where DPS is concerned.
I am interested in leveraging DPS in a classroom setting with approximately 40 computers, all licensed with at least Web and Design Premium.
If possible, I would be grateful for pricing for the Professional and Enterprise licenses for DPS.
Additionally, if anyone could explain the differences, along with costs for uploading apps for review and distribution by Apple, this would be wonderful.
Thanks in advance for any assistance, either from kind and knowledgeable forum readers, or Adobe staff-
Timothy

Thanks Bob for your swift reply. I greatly appreciate the ability to correspond related to my query.
The goal is to teach students to integrate the Creative Suite CS6 (in this case, primarily Photoshop, Illustrator, InDesign/Incopy) and Lightroom4, into a convergent newsroom environment, with final portfolio in the DPS.
We are designing a curriculum where the final project for students will be a student-created magazine/journal to be distributed via the appstore for alumni outreach.
We have a campus site license with Adobe however our IT staff have no information on DPS, or at least they are unaware of it at this time.
Currently I am working on writing a grant with a deadline of next week, Friday January 25. I want to include costs for licensing of DPS for Education, however I have requirements to adhere to.
In particular, I am not permitted to allocate monthly subscriptions into a grant of this type, rather, the licensing costs must be based on 1-time outlays.
If there were additional charges necessary to upload a finished magazine, that would be fine, but monthly charges (ie subscriptions) would not be possible.
Thank you again Bob. I have attempted to contact Adobe Education via this forum and email however it remains (now, and in the past) challenging for me to actually speak with someone.
Cordially with appreciation for your expertise, and willingness to share your perspective-
Timothy

How to I get Graphic Drivers for Windows 7 using Bootcamp on my Late 2011 17" MacBook Pro?

I just received my new 17" Late 2011 MacBook Pro to replace my older model MBP. I had configured the older MBP with two 500Gb SSD drives by replacing the original hard drive and the DVD with 500Gb SSDs. Works fine. I then simply installed these two SSDs from the older MBP on the new machine. OSX works fine, after a few software updates. Likewise Win 7 Pro is installed on a Boot Camp partition with the drivers from the Mid 2010 MBP. Windows seems to run fine after the expected reactivation, but the graphics are obviously not running at full resolution, I am certain this is due to the differing graphics card between the Mid 2010 MBP and the Late 2011 MBP.
Apple does not show any drivers download for the new MBP, I am running BootCamp software version 4.0.
Although I could certainly do it, I don't want to spend the time to run a new installation of Windows 7 and reinstall all the myriad windows updates. It would take hours.
I know that the new installation process takes a step to download the BootCamp drivers, but how can you reinitiate this process after installing BootCamp as I have without progressing through the whole installation process?
Any help appreciated.....

"At least 16 GB of free space on the disk onto which you’re installing for 32-bit, or 20 GB for 64-bit (for Microsoft Windows and Windows-based applications)."
That's what Apple proposes in here Boot Camp: System requirements for Microsoft Windows
Personally I would double these amounts and add to that the diskspace needed for your Windows games.

GPU/CPU Temps and Graphics Performance Questions

I am also experiencing some similar oddities with my 15in UMBP. As background on my setup I am running 10.5.7 (the problem began before the update) and I work in an air-conditioned office with a cooling pad for my frequently "toasty" MBP. I have noticed that my temps are significantly higher while running on the NVIDIA 9600M GT vs. the 9400M, and also I use iStat to monitor my system.
Here's the problems. With only Mail, iChat, Safari 4, and iTunes running (87-93% idle) I frequently see temps hit 150-155 F for the GPU 145-150 F for the CPU. While running on the 9400 with the same applications (87-92% idle) I see temps from 90-95 F for both GPU and CPU. When I had first gotten my MBP I used it mostly with Aperture 2 and I thought it was strange that I couldn't tell the difference in performance between the 9600 and the 9400. Later I tried to use it from time to time in Win XP (bootcamp) for gaming, but it would get so hot that i could hardly touch the keyboard and the graphics performance wasn't nearly what i thought it should be. In fact I was only able to run games slightly better than on my company provided Dell Inspiron D620 (old POS). On the Mac side I tried to test out the performance of my GPU by setting the graphics in X-plane just to the point that with the 9600M GT enabled the program wouldn't tell me that I had too many graphics options turned on. After getting that dialed in I switched over to try it with the 9400 and the performance was nearly identical, and maybe even a little better... I'm not a genius when it comes to computers by any means. I don't know very much about what kind of performance I should be seeing from these two cards, but I would think that the 9600 would greatly out perform the 9400.
Any feedback or advice would be greatly appreciated

I used istat pro to get the temperatures and fan speeds. You can download it free here:
http://www.apple.com/downloads/dashboard/status/istatpro.html
I turned it on a few hours ago and the temperature of one of the cores reached 70 degrees C and the fan speeds all went up to around 3000 rpm. I'm just going to leave it off for now and take it in to get serviced. Only problem is I have to make an appointment and who knows how long it will take to get it in. Hope it works out for you.

MBP Retina 13inch cannot install graphic drivers in windows

Dear All,
I downloaded the latest bootcamp drivers on my MBP 13inch retina late 2013. I use windows 7 pro 64bit on it only Bootcamp seems to install everything except the the intel and nvidia graphic drivers. I'm running Mavericks 10.9.1 if that is any use and downloaded BootCamp 5.1.5640
Please help.

Thanks for your help but no luck. Windows is already installed with older boot camp drivers. I performed a repair with the boot camp drivers but the graphic drivers still wont install.

Updating graphics drivers for m6-1158ca

I've had a crazy hard time finding the solution for a switchable graphics driver issue that's been ongoing since I updated to Windows 8.1 in November. I've had recurrent Display 4101 errors, stating:
"Display driver amdkmdap stopped responding and has successfully recovered."
Basically about once to twice a week, I see this error when I wake up my computer from its sleep.
I tried installing the updated HP driver for my notebook's Intel Graphics 4000, updated for Windows 8.1, to be met with the error "This system does not meet the minimum requirements." I consulted with Leshcat's support forums and determined that an Intel driver was necessary, but I just didn't have the right one. I heard that AMD now supports switchable graphics, but I thought that simply meant it does once both drivers are installed.
I have already tried Leshcat's 13.12 drivers, an attempt that ended in failure. The Intel driver installed but the system never used it: it lay dormant in Device Manager while the Microsoft Basic Display Device was in use. I was told by Leshcat community support that installing AMD's driver over top would not work if the Intel driver was not ebabled. Anyway, I was frustrated by that and restored from a system image.
Now Intel's Driver Update Utility gives me this message, unlike before:
"A customized computer manufacturer driver is installed on your computer. The Intel Driver Update Utility is not able to update the driver. Installing a generic Intel driver instead of the customized computer manufacturer driver may cause technical issues. Contact your computer manufacturer for the latest driver for your computer."
This goes against Leshcat's instructions for finding an appropriate driver.
After months of looking for solutions, I came across this thread just an hour ago in which DavidPK states that the single AMD driver will cover both integrated and discrete graphics. I was pretty surprised, after posting on several forums and probably a hundred articles, that this was the first time I saw this information.
My question is, though, what driver do I actually need to use? If I go to the support page for my system, then the latest AMD driver is the one I currently have and was preinstalled, version 8.982.10.6000. Since there is strong evidence of a compatibility issue with Windows 8.1, I doubt a reinstall of this driver will fix this problem. In the link above, DavidPK suggests this driver from January 2013 that is supposedly compatible with Windows 8.1, despite only being four months newer than mine and nine months shy of the public Windows 8.1 release.
If AMD does support switchable graphics now, would it be so horrible to use their latest 14.4 driver?
Another thing: do I uninstall my current drivers, as Leshcat advises, or do I follow Cloud_Strider's instructions and install a new graphics driver package over top what is already on my system?
Thanks in advance for any help!

Help, please! I've been putting up with these errors for a year now. I've tried everything.
HP, please help a customer out.
