T520 - 42435gg / Sound stutter and slow Graphic performance with Intel Rapid Storage AHCI Driver

Hi everybody,
I have serious Problems with my 42435gg
Any time I install the Intel Storage AHCI Driver (I've tried plenty of different versions) which is suggested by System Update I experience a horrible Sound stutter and slow Graphic performance in Windows 7 64-Bit.
The funny thing in this case: If the external e-sata port is connected the problems do not occur. If the port is unused again, the stutter begins immediately.
The only thing I can do is using the Windows internal Storage Driver with which I am not able to use my DVD recorder for example.
The device was sent to lenovo for hardware testing with no result. It was sent back without any repairing.
Anybody experience on this?
Kind regards,
Daniel

Did you try the 11.5 RST beta? Load up DPClat and see if DPC conditions are favorable.
What are you using to check graphics performance?

  • Very slow network performance with Intel NIC when TCP Large Send Offload is enabled

    I have a Windows 2008 server with two NIC's (Intel PRO/1000 PL and Intel PRO/1000 PM), and one virtual external switch connected to each NIC.
    With the 01/14/08 network driver, I get very low throughput on both NIC's (~10KB/sec when downloading from my server when it should be around 11MB/sec).
    I've found that disabling "TCP Large Send Offload (IPv4)" on the virtual switch and "Large Send Offload v2 (IPv4)" on the physical adapters solves the problem.
    Is this a bug in the driver?
    Thank you,
    Ricardo Costa

    2 years later, I was able to get that machine to work with Hyper-V under Windows Server 2008 R2, but only after disabling everything that had anything to do with TCP or IP offloading.  I think that I had to turn off 4 settings on one controller,
    and 5 settings on the other controller.  Once that was done, everything worked flawlessly.  It is very apparent that the Virtual Controllers do not properly use many of the features of non-Intel devices (not all Intel devices work either), and
    that Hyper-V does not completely uninstall if you remove it.
    If you have any problems, start turning off the features that your adapter supports, until it starts working.  You'll need to weight the cost of replacing the controller with a fully supported controller, of which there is no list, or using your existing
    controller at a capacity lower than it physically supports.  This has been an elusive issue with Microsoft's Virtual Server projects since they were first in beta, so don't expect a fix anytime soon.
    P.S. For those who don't know, the settings are on the actual device and can be changed in the Device Manager.  If you are still having trouble after turning off all the settings, then you will need to replace the controller(s) with a different
    make/model.

  • Hello. I have a new Computer and import my mediathek with an externe storage. When opened the new Mediethek in front of every song there is a explanation mark: original song could not been found. I try everything. Whats the Problem??

    Hello. I have a new Computer and import my mediathek with an externe storage. When opened the new Mediethek in front of every song there is a explanation mark: original song could not been found. I try everything. Whats the Problem??

    But it seems the OP has a setup where the media is on the external drive, and the library files are on the internal. This is what I refer to as a split library, Migrating such from one computer to another is not straightforward. Often iTunes will have some definite idea about where the files should live, and updating the setting of the media folder won't change that. If it requires a drive letter change that is usually not too hard, but sometimes there is another preference file that needs tweaking to indicate which of the old & new layouts for the library is being used. In more extreme cases I have a script for automatically making track by track repairs.

  • Intel Rapid Storage Technology and the Envy 700-330qe

    I have a new Envy 700-330qe CTO. One of the suggested driver updates on the hp support is for Intel Rapid Storage Technology. I initially thought that this was a driver for hardware like my old Pavilion had (it had an Intel Matrix Storage Manager board which managed RAID 0, 1, or 0+1).  Now I see that it is a RAID software emulation program. Nowhere in the documention that came with the machine is there any mention of this machine's capability to run any form of RAID. I do have two HDD's and they are the same size, so theoretically I could run RAID 0 or 1 if I so choose, but nowhere is there any mention of a way to do this. I did see that the BIOS must be set to run RAID.
    I am NO expert. I was wondering where I can find further into on how to set up a machine with RAID. Thus far, I have not even taken a peek at the BIOS (not even sure how to do this, so some of you may think I am stupid). I guess I get a  bit bent out of shape when a product has features that should be out in the open but appear to be hidden. Any help would be reallyhl appreciated.
    This question was solved.

    Hi,
    I am sure that you noticed that the HP configurator doesn't offer an option to cache a RAID configuration.  The Intel IRST MSATA caching functionality does rely on the RAID setup process to activate caching on one HD.

  • Mac mini VPN headless, slow graphics performance when no monitor plugged in

    I am using a Mac mini, headless, with no monitor, keyboard or mouse, via VPN from a Windows machine over a LAN. Everything works fine and setting everything up was a breeze. However, something very odd I noticed was that if my Mac mini does not have a monitor plugged in to its video output, the rendering of the graphics over the VPN is very slow. It is most noticable when hovering over the dock and activating the animations etc, though it is noticable all the time. It's so bad that it would be IMPOSSIBLE to watch a video clip or simple animation. It's as though frames are being dropped. Now, this can be immediately fixed if a monitor is plugged into the Mac mini and turned on, and the VPN to the Mac mini from my Windows machine works flawlessly and the graphics are rendered perfectly, with little to no delay or frame skipping.
    I have a hunch that the Mac could be disabling some kind of graphics acceleration when the monitor is not plugged in, but I am not a Mac expert by far, this is my first Mac experience. It was purchased solely for the VPN and headless use, so if I can't get it working properly, it's a waste.
    Note, I have tried several VPN client/viewer combinations and they do not change the situation.
    Thanks in advance.

    Also, when I try to use the remote with the Mac mini (pressing the menu button), over VPN with no monitor attached to the machine, I simply get a white blank screen until I press the menu button again.

    I must have been HALF ASLEEP when I wrote this.
    I do not mean VPN, I mean VNC!!. Sorry for the confusion.

  • ITunes sounds scratchy and slow

    When I play songs in iTunes, they sound scratchy and have pops in them. At about 8-10 seconds in, it really slows down for a second or two and then seems to free up a bit, but not without the scratching and pops.
    I have iTunes 7.0.1.8 running on Windows XP. I have searched through the forums and tried all the suggestions I have seen about the QuickTime preferences, updating DirectX, etc. Nothing seems to help 100%. Any ideas????
    eta - It gets worse when the CPU seems to be running at high capacity - (like opening an app or ie or something).

    Bump - Anyone out there experienced the same thing???

  • Ringtone sounds 'droopy' and slow on N97

    Hi,
    As I'm discovering some of the little annoyances about this phone I will endeavour to have someone at Nokia to please advise me. Lates booby is the ringtone...................... Everytime the phone rings it sounds like it is playing on a tape cassette player with barely enough battery to turn the spools. how can this possibly be when everything is digital? The sound is horrible and droopy and slow!
    Has anyone else had this problem?

    All fixed after several firmware updates. Pity the same can't be said for the horrible Nokia Ringtone issue. This problem has not been fixed and is exacerbated by the fact that Nokia regardless of how many emails I send them do not respond any further than the automated reply stating they will get back to me within 48 hours.
    Never happens.............Where did it all go wrong Nokia? When did you decide that silence was the best policy?

  • Stutter in Slow Push-In with Dissolve

    I'm working on a G5 running FCP 5.0.4, Blackmagic 8bit uncompressed SD video.
    I am dissolving from shot 1 to shot 2. Shot 2 has a slow (2 keyframe) push-in with the in point at the start of the dissolve. After rendering the move, during playback the push-in appears to stutter as the end of the dissolve.
    Has any one else had this happen? If so, please help me.
    Thanks,

  • Intel GM45 (x4500M) terrible 3d performance with intel driver and mesa

    I have following problem with my Lenovo SL500 laptop. I have installed new xorg-server 1.5, mesa 7.2, libgl 7.2 and intel driver 2.4 with libdrm 2.3.1 and intel-dri 7.2 (from testing repository) and generated xorg config.

    Apparently yes,
    According to the thread:
    To restore to the old behaviour, put this in your ~/.drirc:

    But I don't come back to the same perfs as before (tested with eternal lands).
    I noticed that in my /var/log/Xorg.0.log:

  • SLOW report performance with bind variable

    Environment: 11.1.0.7.2, Apex 4.01.
    I've got a simplified report page where the report runs slowly compared to running the same query in sqldeveloper. The report region is based on a pl/sql function returning a query. If I use a bind variable in the query inside apex it takes 13 seconds to run, and if I hard code a string it takes only a few hundredths of a second. The query returns one row from a table which has 1.6 million rows. Statistics are up-to-date and the columns in the joins and where clause are indexed.
    I've run traces using p_trace=YES from Apex for both the bind variable and hard coded strings. They are below.
    The sqldeveloper explain plan is identical to the bind variable plan from the trace, yet the query runs in 0.0x seconds in sqldeveloper.
    What is it about bind variable syntax in Apex that is causing the bad execution plan? Apex Bug? 11g bug? Ideas?

    Patrick, interesting insight. Thank you.
    The optimizer must be peeking at my bind variables with it's eyes closed. I'm the only one testing and I've never passed %anything as a bind value. :)
    Here's what I've learned since my last post:
    I don't think that sqldeveloper is actually using the explain plan it says it is. When I run explain plan in sqldeveloper (with a bind variable) it shows me the exact same plan as Apex with a bind variable. However, when I run autotrace in sqldeveloper, it takes a path that matches the hard coded values, and returns results in half a second. That autotrace run is consistent with actually running the query outside of autotrace. So, I think either sqldeveloper isn't really using bind variables, OR it is using them in some other way that Apex does not, or maybe optimizer peeking works in sqldeveloper?
    Using optimizer hints to tweak the plan helps. I've tried both /*+ FIRST_ROWS */ and /*+ index(ps pk_persons) */ and both drop the query to about a second. However, I'm loath to use hints because of the very dynamic nature of the query (and Tom Kyte doesn't like them either). The hints may end up hurting other variations on the query.
    I also tested the query by wrapping it in a select count(1) from ([long query]) and testing the performance in sqldeveloper and in Apex. The performance in that case is identical with both bind variables and hard coded variables for both Apex and SqlDeveloper. That to me was very interesting and I went so far as to set up two bind variable report regions on the same page. One region wrapped the long query with select count(1) from (...) and the other didn't. The wrapped query ran in 0.01 seconds, the unwrapped took 15ish seconds with no other optimizations. Very strange.
    To get performance up to acceptable levels I have changed my function returning query to:
    1) Set the equality operator to "=" for values without wildcards and "like" for user input with wildcards. This makes a HUGE difference IF no wildcard is used.
    2) Insert a /*+ FIRST_ROWS */ hint when users chose the column that requires the sub-query. This obviously changes the optimizer's plan and improves query speed from 15 seconds to 1.5 seconds even with wildcards.
    I will NOT be hard coding any user supplied values in the query string. As you can probably tell by the query, this is an application where sql injection would be very bad.
    Jeff, regarding your question about "like '%' || :P71_SEARCH_SOURCE1 || '%'". I've found that putting wildcards around values, particularly at the beginning will negate any indexing on the column in question and slows performance even more.
    I'm still left wondering if there isn't something in Apex that is breaking the optimizer "peeking" that Patrick describes. Perhaps something in the way it switches contexts from apex_public_user to the workspace schema?

  • Very Slow SMB Performance with DroboShare

    Hi there,
    We have a big issue with a DroboShare NAS device connected to a Drobo Drive (FAT32):
    If we connect to our DroboShare NAS directly via LAN, the performance with SMB is terrible. Browsing folders takes minutes until the contents (15 items) are shown, opening and saving files takes minutes.
    If we connect the Drobo via USB to one of our Macs and then share it via SMB, it is fast as ****.
    Problem is that we cannot leave it this way, as we only have portable macs, so if they are removed, nobody can access the Drobo.
    The problem nevertheless seems to be restricted to Macs: If we connect to the DroboShare with Linux or Windows Boxes, everything is as fast as expected.
    Does anyone has similar issues with weak performance and/or knows how this can improved?
    Any help is greatly appreciated.
    Thanks,
    Simon

    I just ported netatalk (AFP) over to the DroboShare.

  • Slow system – problem with OS, software, memory, hard drive?

    I am running a MacBookPro5,3 (Intel Core 2 Duo – 2.8 GHz, Memory = 2 x 4 GB, Hard drive = NVidia 500 GB - 100GB of which is free space), using Mac OS X 10.6.3.
    I was running 10.6.6. Then attempted a software update to 10.6.7 and the system essentially stopped working, Was able to back up data using target disk mode, and then reinstalled 10.6.3 using a purchased snow leopard DVD (had lost the disk that came with the computer). Worked for a while but have been having issues with increasingly long and frequent system slow downs (spinning beach ball). Recently attempted another system update, and the update failed and wasn't able to do anything. Used the 10.6.3 dvd and did a disk utility check – it initially said there was a problem with the hard drive – but on another restart from the DVD this issue disappeared (but still no working OS). Attempted connection of my computer to another laptop using target disk mode – this failed to show the target hard drive and only showed the dvd which was in the computer booted up in target disk mode.
    At this point rebooted using the DVD and was able again to install system 10.6.3. However, there are still occasions of sporadic slow-downs associated with specific applications (spinning beach ball for anywhere from 5 – 120 sec). Ran disk utility from the DVD again – states that the permissions and the hard drive is OK. Also, ran a memory test (using Rember) which stated that everything was fine (although the test took nearly 2 hours to run and was punctuated by much spinning beach ball activity).
    At this stage i am not sure whether I have a problem with memory, the hard drive, the OS or the software. Clearly something is not right – are there any other options to test my system (since I don't have the original dvd – I haven't been able to run a system hardware test) - other third party options?
    Thanks in advance for any advice, and apologies for long post.
    Rob

    Sounds like a failing hard drive or SATA controller. It's not clear whether you have a backup of your data. If not, you should remove the hard drive from the machine and install it an external enclosure or dock, then back it up using another Mac. Then take the unit to an authorized service outlet for testing.

  • Graphic failure with Intel Graphics

    Hi!
    I got my new MBP 15" i7 two weeks ago and installed all updates that were available.
    I have noticed that if I watch movies in fullscreen mode with the Intel gfxCard and a Growl message appears or if I move my mouse cursor to the hidden dock some graphic failures show up:
    http://img.skitch.com/20100904-by9mfjq6uantsn752ftjc9sg1b.jpg
    This also happens in screensaver if any popup (growl...) appears.
    Thanks a lot!
    StonerL

    Are you forcing the computer to stay on the intel graphics chip with a program (like gfxCardStatus)?
    I have the same computer, but for anything other than simple internet browsing my computer automatically switches to the dedicated nVidia card. As soon as I put up a full screen video or even an app like MS Word it switches cards.

  • Dv9260us - Is Intel Rapid Storage possible and what is the SATA speed supported

    I was reviewing a post for upgrading my dv9000 to Windows 7. I noticed they there was a link to the drivers for the Intel Chipset but immediately below it was a link for Rapid Store Technology (for RAID). This laptop has two drives and I never saw anything about Rapid Store on the laptop before. Is it possible to implement this? Also, it seems the two drives that the unit comes with max at 1.5 Gbit/s and I'm trying to determine if the board support 3.0 Gbit/s. Answers to the above would help me choose the right parts. If Rapid Store can be implemented I'll buy 2 new drives. If the board supports 3.0 I'll get a faster drive (possibly two if Rapid Store can be used). Thanks in advance...

  • Slow graphics performance - login screen, launchpad, full screen video all stutter

    Since installing Mavericks, I've found that several system animations are slow/stutter. This is on a 2012 MacBook Air with maxed out hardware specs so its not b/c I'm running an old system.
    Some examples:
    - When booting up, right before I reach the login screen, the display quickly flashes blue. This leads me to believe something funky is going on with my graphics card/drivers
    - The login animation, where you click your username and it floats to the middle of the screen so you can type in your password, is very jerky, taking 2+ seconds to complete. Previously it had been fast and smooth
    - When using Launchpad, expanding folders often takes several seconds. The folder will start to expand, freeze, and then finally finish. This tends to be more of a problem for folders with 1 row of icons. Large folders oddly seem to expand ok / smoothly
    - Watching full screen video in iTunes causes the audio to stutter (the video playback is still smooth). If I make the window smaller, audio and video playback are smooth again
    Is anyone else experiencing these kinds of graphics issues? Any idea whats going on or how to fix?

    Quit Chrome and see whether there's any change. If not, see below.
    Step 1
    When you notice the problem, launch the Activity Monitor application in any of the following ways:
    ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
    ☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
    ☞ Open LaunchPad. Click Utilities, then Activity Monitor in the icon grid.
    Select the CPU tab of the Activity Monitor window.
    Select All Processes from the View menu or the menu in the toolbar, if not already selected.
    Click the heading of the % CPU column in the process table to sort the entries by CPU usage. You may have to click it twice to get the highest value at the top. What is it, and what is the process? Also post the values for User, System, andIdle at the bottom of the window.
    Select the Memory tab. What value is shown in the bottom part of the window for Swap used?
    Next, select the Disk tab. Post the approximate values shown for Reads in/sec and Writes out/sec (not Reads in and Writes out.)
    Step 2
    If you have more than one user account, you must be logged in as an administrator to carry out this step.
    Launch the Console application in the same way you launched Activity Monitor. Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left. If you don't see that menu, select
    View ▹ Show Log List
    from the menu bar.
    Select the 50 or so most recent entries in the log. Copy them to the Clipboard by pressing the key combinationcommand-C. Paste into a reply to this message (command-V). You're looking for entries at the end of the log, not at the beginning.
    When posting a log extract, be selective. Don't post more than is requested.
    Please do not indiscriminately dump thousands of lines from the log into this discussion.
    Important: Some personal information, such as your name, may appear in the log. Anonymize before posting. That should be easy to do if your extract is not too long.
