FireWire 400 and 800 speed question

I recently bought one of these cords off of eBay for a few dollars.  I have an old external WD which was connected by usb 1.0.  I thought I could get more speed with this cord, but I get all the same read and write speeds of close to 23MBS.

Any ideas why the speed is slow?  Cord? By car?

Thank you!

USB 1.0 MAX is 12 Mbps, which is 1.5 Mbps. (b = bit, B = byte [8-bit]).

FireWire 400 MAX is 400 Mbps, which is 50 MB/s.

Without knowing the specifications of the car, I guess that the "old external WD' performance is the limiting factor.

    Hello..

    I have a Satellite A100-906, and I wanted to ask if anyone knows if the i.LINK (IEEE 1394) in my laptop connection is the firewire400 (a) or the type of firewire800 (b)... I want to buy an external hard drive with firewire connection...

    Thank you

    Hello

    Firewire IEEE 1394 a supports an old cable 4 - pol and jack and IEEE 1394b firewire supports a new cable 6 - pol and new plugs.

    On this picture you can see two catches:

  • Can I use several adapters to convert a Firewire 400 in Thunderbolt connection?

    I have a firewire 400 device I want to connect to a Thunderbolt connection.  Can I use several converters for first shot of firewire 400 and 800, and then use the Apple firewire 800 adapter Thunderbolt?  Otherwise, any other suggestions?

    Perhaps, but not all cards can work in tandem. But why waste time and money. A FW 400 device won't run any faster on Thunderbolt. Why do you need to do this, and do you have looked for a better solution?

  • U350 (Intel SU2300) memory speed question

    Hi all

    I was wondering, is there a way to increase the speed of the memory in u350?

    Module of memory in my u350 is Hyundai ddr3 rated at 533 mhz (1066 mhz ddr) but it works

    by default, only 400 mhz (800 mhz ddr).

    Supports the module memory, chipset (Intel GS45 almost certainly supports it) I do not have

    See a reason why ram should run at low speed and then he pointed to work to...

    is cpu maybe limit it?

    TNX for the answer

    To exy s initial question:

    "Supports the module memory, chipset (Intel GS45 supports almost certainly it) I do not have.

    See a reason why ram should run at low speed and then he pointed to work to... »

    Modules are designed to operate at different speeds.

    The processor and chipset are designed for low power usage.

    Memory speed is equal to the lowest energy consumption. (And more strict timings of memory)

    Looks like a good choice for me, FSB/MEM = 1 / 2 = 800/400

    Most of the laptops I've seen opt for low mem speed and better timings.

    (6 6-6-18 vs 7-7-7-20 for example)

    And not a very noticeable difference in performance, IMO.

    But looks like a design for low power usage decision.

    I'd be willing to bet that you get very good battery life.

    Hello

    The following link shows the specifications of your computer:

    http://support.HP.com/us-en/document/c03046669

    It has:

    Expansion slots:
  • The two lines EX90 and add speed dial

    My friends, I need help in this case, we replaced digital phone with EX90 new to our general manager. but there is some functionality was available on the old phone:
    1 - the old phone has buttons around the screen as a speed dial buttons for certain numbers of employees
    2 - the old phone has two lines one private and one is the direct line

    Here, he wants the same features on the EX90:
    1. I configured the favorite on the EX90 as a shortcut, but he wanted the speed Dial buttons appear directly on the screen for

    press about this directlry.
    2 - I have configured the EX90 on CUCM and added the second row but he only appeared, if there is a method to allow

    calls on the (direct and private calls on different lines) EX90

    Please I need your urgent help

    The DefaultPanel Option is only in more recent versions of TC software, I do not remember what version it appeared in, but it is there in the last TC7.1.3.  If you don't, you probably use an older version of software on your EX.

    It is located in the web interface under Setup, System Configuration, UserInterface touchscreen Panel default.

    The options are: none, last, list of contacts, MeetingList and keyboard.

    The option of contact list

    Another option (although, as for a simple speed dial) is the installation Service that puts a button in the upper left corner of the touch screen.  Note: Only facility Service 1 is available in the Panel even if you configure 5 of them.

  • Can you have bookmarks in a document of fm and other beginner questions?

    Hello

    I just took an assessment of Framemaker to accelerate the generation of pdf and html, as I currently

    Use a single source tool developed in-house.  I used latest Framemaker when it was version 6 and I

    a few questions about things I would like to be able to do:

    Can I view the bookmarks in a document, standard framemaker, like in Word? I find that this makes it easier to

    navigate around the documentation, or is there a better way? I don't know their definition in the PDF file, this

    is for me as the author...

    I got just the Autonumbering once again kick, but have not found out/understood how to keep my legends of the figures

    with the images that I imported a framework anchored, if any help you can give me would be appreciated

    with that.

    Output PDF is great and the speed of the savings is ideal even for large documents. Is there a real advantage

    have a lot of several chapters in a book, rather than a long document? My longer document is of approximately

    280 pages and consists of four sections, with Appendix, glossary, index and table of contents.

    Output HTML seems to be as bad a I remembered 6 years when I used Webworks Publisher to

    perform the conversion. RoboHelp is a good alternative I organized an assessment from next week

    so have not had the chance to look at this yet, but would be interested in what people think.

    Thank you very much in advance for your help.

    See you soon,.

    Hi, Karen:

    In FrameMaker documents, you can navigate to something that will become a link in a PDF document to its source, with a "hyperclick" on the page entries table of contents and indexes in the generated files and references or hyperlinks not generated documents. A hyperclick is Ctrl + Alt + click. There is no click back. You can lock the FrameMaker documents to make these active links with a single click and use the dos commands and others on the Navigation menu that appears when a locked document is active.

    To lock or unlock a document for the type of hypertext navigation and release these keys in order: F Escape (must be uppercase) l (lowercase ' el' not important 'eye' or number one) k (must be lowercase). I remember as "(F) Island (l) oc (k).»

    Google search for words like 'Lock of FrameMaker for hypertext Documents' and "FrameMaker navigation Menu" without the quotes, for more information on these techniques.

    Also, you can use the dialog box insert reference allows to browse some sort of plan file, by selecting a paragraph format such as a cap, on the left and scroll through these paragraphs on the right. Page numbers, you can see the list below indicate the first and last page of the paragraphs in the list above. It's a little inaccurate, but useful.

    You can also generate table of contents or index or list of external cross-references (special > list of > references > external cross references), and then close window of the file generated to fit in the workspace to the sides of the active document. Hyperclick in the generated files, or lock files and a simple click on an entry, to navigate to the location linked in any other file is advanced to.

    HTH

    Kind regards

  • Satellite L500D - SSD and RAM upgrade question

    Hello

    Who are you? Ttime for some great upgades for this laptop and some few questions and I'll be happy to answer for me.

    1. is there an empty space to install a second hard drive SSD?

    2. If there is not can put off the hard drive DVD and in the empty space to fit an SSD? I need something like that? ---> fb4d http://cgi.ebay.com/CF-Card-2-5-Serial-ATA-SATA-SSD-HDD-UDMA-Adapter-/190537923405?pt=LH_DefaultDomain_0&hash=item2c5cf1
    This is an adapter.

    3. the quantity of RAM max supported Satellite L500D? I installed 2GB and I have an extra plug and I want to install a single 4 GB RAM and 6 GB RAM total

    Its sounds good to you this idea? I thank you and have a nice day

    Hey,.

    As you can see on the underside of the laptop doesn t supports a second HDD because there is no second Bay HARD drive on the underside.
    The map you posted is unofficial so no one can say whether it compatible s part or not. For laptops Satellite AFAIK there is no CD/DVD Bay adapter, but you can ask a provider of service authorized for more details.

    The maximum RAM capacity depends on your phone model correct. L500D was delivered with different hardware, so you must post your exact model laptop number.

  • The satellite C855 - raised average temperature and fan speed

    Hello!

    I got this toshiba Satellite C855 since March this year. It is only recently that the CPU temperature and the speed of the fans have been worrying me.

    When I'm not playing games or doing a livestream my CPU temp is about 35-40% with the regular 50% fanspeed or not on because she was cool.

    When I play games however the fanspeed is up around 66 to 68% with the central unit was 55-60%

    I was wondering if this is normal? or I have to clean it by taking it apart. If it's the second option then I'm worried because I don't want to damage anything inside. In addition, I'm not bad with the inner workings of a computer.

    Any help or information would be greatly appreciated thanks.

    In my opinion there is no reason to panic. T is the logic which is higher under stress, activity of the CPU and CPU produces more heat. Laptop needs to be cooled correctly, so the sensors that control the cooling fans sign up for increasing temperature and cooling fans run on higher speed.

    There is no reason for cleaning. And one day if this must be done please don t do it alone. You are not allowed to do this.
