Seeing performance difference when using 6-4- keys but not showing 64 bit k

Forgive me if this has beem documented but i looked and couldnt find anything. So here goes.. I have a macbook 3,1 4gb ram. By all documents I know I will not see the 64bit kernel but when I hold down the 6 and 4 key when I boot up.... OMG, SL loads up like nothing I've ever seen. FAST isn't in the ball park. So I check and yes it still shows 64 bit extension/no.
Has anyone else seen this?

As no Windows 8.x nor 64-bit OS available ATM, I can't check/debug this issue (reported on some forum) by myself --> so, is there some difference in handling hotkeys and/or window functionality between either W7
and W8.x or 32-bit and 64-bit OS?
VC++ 2013.4 in use. Any suggestions welcome?
You need to debug it in the target OS. Use Hyper-V, VirtualBox, or some other virtual environment and install the target OS. These have trial periods, so you aren't out any money.

  • HT5105 I have been trying to create a multicam clip from two camera's. They sync properly when using the sync feature but not when I use the multicam feature does anyone know what I may be doing wrong?

    Probably best if you could post screen shots of the Inspecror window in extended view with a couple of the clips you using for the 2 angles.
    If you have audio from both cameras and have identified them separately, the sync is usually pretty reliable.

  • G5 fans run at full speed when used at one home but not at another!?

    When I use my G5 dual 2Ghz at my house in Atlanta, GA in runs smooth and quiet. When I use it at my house in Rome, GA it starts out fine but the fans ramp up to full speed in about ten minutes. The internal temps are within limits in both locations. The wall sockets are all properly polarized. Any ideas?

    I have G5 Dual 2.0 Powermac. . . . . where the Power Supply blew up (common Problem) . . . . outside Apple Extended Warranty serial numbers.
    I bought a new supply . . . . . from supplier in America . . . . I live in UK.
    It works fine except the the fans seem to have thermal run away to max speed after approximately 5 minutes.
    If I restart or sleep 3 or 4 times, it seems to work OK after that with no speeding up of the fans.
    Monitoring program Istat pro, does not show the fans in its display when the fault is happening . . . . . but the fans appear in the monitor window when its working OK.
    Please tell me if the voltages you use in America and Italy are as I expect (110v 60 Hz US / 220v50 Hz in Italy).
    Perhaps its a voltage thing between Europe and America.
    ........ I intend to try a 110v transformer just to see.

  • When using designer the form will not show up.

    When I activate the form designer to make it interactive, it will not show the form except momentatily.  Is ther a way to turn it up? 

    David,
    I responded to the forum but could not figure how to send attachments to you there.   This is another try . 
    I scanned a form to PDF that I want to, make interactive and fillable.  In Adobe Acrobat 7 I clicked on Advanced > Forms> Make form Fillable in Adobe Design. The results is a conversion to an unreadable Form.  Checking the PDF preview tab does not help.  Attached are the Form and the enteractive form. 
    Is there any suggestions as to what I am doing wrong?

  • AD contains system Recovery Key, but not showing in MBAM.

    I am in an environment with MBAM 1.0 installed. I built the MDT 2013 system here and am currently trying to figure out why the bitlocker keys are showing up in AD but not MBAM.
    In MDT, I have disabled the "enable bitlocker" options so there shouldn't be a case where that the TPM ownership is wrong (I think). I do however set the
    bios password with CCTK, then apply the default bios configuration with an ini via cctk. The bios sets and activates tpm just before the hard disk is formatted by LTI.
    q1. Could setting the TPM without restarting cause the TPM ownership to be set to the PE in some weird way.
    q1.1. would I clear the tpm if this is the issue?
    So MBAM client is installed on the reference image and captured by MDT. The WIM is then deployed to a system using a standard TS with the bitlocker disabled like
    I mentioned above. I do not make any changes to reg for mbam in the reference image. For testing, I tried adding the mbam recovery key location url to the reference image reg. I still need to test that but a few other tests I did makes me believe this
    is not the case.
    MDT binds the system to a default OU in the domain. After the system is configured, I start Bitlocker. (Sometimes I start bitlocker when the system is in the default
    OU, sometimes I start it after I move them into the right ou for the role). I am almost positive the default OU has the mbam settings (I do not have access to this gpo), since the manage-bde -status comes back AES 128 with diffuser (as compared to regular
    aes 128).
    After bitlocker finishes, the key is found in AD but not mbam.
    I think the major questions I have are:
    How can I force MBAM to take ownership of the TPM after the os is bitlockered? (about 100/700 machines are not reporting to mbam but are to bitlocker because of this new deployment system)
    If I turn TPM on and activate while I was in the PE, would that mean the PE has the TPM ownership? (or bitlocker in this case, since mbam is not installed on the PE)
    - Could I install MBAM on the PE and use that to manage the tpm? (MDT 2013) (I have seen some documents that cover this but it largely comes from wanting a pre-provisioned bitlocker.)
    ** I think the most manual way of correcting the issue I am having, is to either clear the tpm and rebitlocker, or
    .. when a system is about to image, turn tpm on but leave it deactivated. (If I leave the tpm deactivated, every system will need to be manually rebooted and f10 will need to be pressed to continue the bitlocker process. this includeds
    a user login too)

    Keep the MBAM out of the .wim! Install it in task sequence.
    MBAM Client has its own log files in event viewer, there you perhaps find the reason why recovery key is not stored in DP. But fix your image first, keep it thin.

  • Firefox drops letters when using Franklin Gothic webfont, but not Safari

    I have bought the web version of Franklin Gothic Book, Medium and Demi from MyFont - and started to use these in my new site in development.
    We have hit a few problems which has caused me to have to reconsider the whole issue - unless help us at hand:
    Problem 1 - Firefox drops several letters/characters and so is no use to me at all as it is.
    The problem doesn't happen in Safari.
    Problem 2 - Font looks poor at about 20px size - in any browser on Windows XP - see attached 3
    I would really like to have the fonts on my new site - and wasn't anticipating any problems bearing in mind the publicity fonts on sites has been getting over the last 12 months. However, I may need to ask for my money back unless we can get this version of Franklin Gothic Book, Medium and Demi to work.
    Screenshots and urls available on request

    It's a problem with the font.
    The font has the ligature characters removed, but the ligature tables are still there. MyFonts says you should be able to regenerate the font with the full character set:
    ''You should be able to log in to your account, Access your 'Order History', select the appropriate purchase, then select 'Webfont Kit Builder', just to the right of 'Easy', and 'Desktop Font Downloads'. If you click on the Font sample (the quick brown fox), you will see advanced character options. Please choose Keep Open Type Layout (complete character set will be automatically selected) and download the kit. ***(If this option is available for your font you will want to select the font under 'Available Webfonts' on the 'Webfont Kit Builder' page, then, under 'Selected Webfonts -> OpenType Layout', check the 'Keep All OpenType Layout.' option.)***''
    If the problem persists, or if you can't regenerate the webfont, and you only need to support Firefox 4+, you can work around the problem by adding -moz-font-feature-settings: "calt=0,liga=0"; to your @font-face.
    If you also need to support Firefox 3.6, you can use text-rendering:optimizeSpeed; as an alternative workaround.

  • Performance degradation when using foreign keys

    Hi,
    I face drastic performance degradation when I add foreign keys to a table and perform insert / update on that table.
    I have a row store table to  which I need to insert around 1,50,000 records.
    If the table has no foreign key reference it takes maximum of 5 seconds but if the same table has references to other tables (in my case there are 3 references), the processing speed reduces drastically to 2 minutes.
    Is there any solution / best practice that can help me in gaining performance (processing speed) in this situation?
    Thanks
    S.Srivatsan

    Hi Sri,
    When you perform one insert in any database table which is having foreign key relationships, it will check the corresponding parent tables to check whether the master data is available or not. If your table is having 2 foreign key relationship, it happen twice per insert. Hence the performance will degrade. This is one of the reasons why ECC  doesn't establish foreign key relationship in the back end database. The case is not just for INSERT, for UPDATE & DELETE the same is applicable.

  • I have replaced my ibook hard drive but when I start up I get a folder with a flashing question mark. I have tried installing the OSX disk using the "C" key but can't get any further than the flashing "?." What do I do? What is the problem?

    I have replaced my ibook hard drive but when I start up I get a folder with a flashing question mark. I have tried installing the OSX disk using the "C" key but can't get any further than the flashing "?." What do I do? What is the problem?

    Which iBook do you have?
    http://support.apple.com/kb/HT1772?viewlocale=en_US
    Which version of the OS is installed, and which version are you trying to install?
    You could try starting up with Startup Manager and see if it will allow you to select the OS X install disc as the startup disk. If so, maybe you can proceed from there. I would recommend repairing the hard drive first since you are evidently having a bit of a problem with it.

  • Performance problem when using CAPS LOCK piano input

    Dear reader,
    I'm very new to Logic and am running into a performance problem when using the CAPS LOCK-piano-keyboard for input of an instrument: when I'm not recording everything is fine and the program instantly responds on my keystrokes, but as soon as I go into record-mode there is sometimes a delay in the response-time (so I press a key and it takes up to half a second longer before the note is actually played).
    Is there anything to do about this to improve performance (for example turning of certain features of the application), or should I never use the CAPS LOCK keyboard anyway and go straight for an external MIDI-keyboard?
    Thanks and regards,
    Tim Metz

    Does your project have Audio tracks and just how heavy it is, how many tracks? Also, what kind of Software Instrument do you use?

  • Performance hit when using a FirePro GPU?

    Hey there!
    I'm interested in purchasing a cheap ATI FirePro V4900 or similar GPU in order to take advantage of my 10 bit TFT when using Photoshop. I was wondering if I have to expect a performance hit when using PS 6.0 with such a card as opposed to a normal "gamer" GPU like the NVidia 670 GTX when :
    - performing normal file handling, opening PSD files, paning, zooming, brushing, etc.
    - applying some of the newer GPU-enhanced filters like Liquify, Oil Paint, Iris Blur, 3d enhancements, etc.
    - actually applying/rendering a more demanding fliter such as Iris Blur?
    Does anyone know about this? I'm afraid I could not find any benchmarks at all except for the one on Tomshardware regarding OCL, but that one does not include professional GPUs...
    Thanks for any info in advance!

    There will not be synchronization when the method of A
    is being called. The method 1) certainly saves memory
    space, but will the performance be hurt since there
    will only be one object accessed by multiple threads?
    Or maybe it doesn't matter?If there is no synchronization, it will not matter. Threads execute methods. Methods do not run on Objects. The Object is just data that is implicitly linked to the method.
    Just make sure it's safe to keep the method unsynchronized.
