Processor choice for W540

I wanted some help regarding selecting the processor for W540.
I see the options available and I'm intersted in 2 of them which are i7 4900MQ and i7 4930MX.
There is quite a price difference between the two but if the extreme cpu can offer more in the long run I'm up for it.
But I had a few concerns before making the choice.
I'm concerned about the temperature of the laptop if I choose the 4930MX it might be too high to handle since I'm not flexible with high temps, my current laptop which is a W530 idles at 45C and at full load can go upto 75C very rarely even after running 3 VMs.
Can anyone advice regarding the same and provide the temps for idle, normal workload and full load temperatures for 4930MX.
If the extreme processor is too hot to handle I can go with 4900MQ as well which has a lower TDP which in theory would run cooler.
I'm mostly concerned about the heat as I can't stand hot laptops.
Can anyone advice regarding the same and point to the best option between the two.

The 4930MX is not worth the money, just grab the 4900MQ. The most noticable difference compared to the 4800MQ is the 2MB of extra L3 cache you get and a slightly higher clock. If you really want to pay 500$ on avg more for a 4930MX that is maybe 5% faster that's just a bad idea.
Just get the 4900MQ and save yourself some money towards your next purchase.
Also the W540 doesn't allow overclocking the CPU I think, so there is no real benefit getting the 4930MX as far as I know, unless you can overclock it with Intel XTU.
Hope this answers your question.
Also if you prefer lower temperqtures and you don't do heavy CAD or gaming, you can opt for the K1100M which should also make the W540 run slightly cooler.

  • Which of these 2 laptops would be my best choice for editing video?

    I am going to get a new laptop mainly to use for LR and PS but I also want to be able to edit video.  Which of these 2 laptops is my best option...
    ASUS ROG G751JT-CH71
    Intel Core i7-4710HQ 2.5 GHz
    16 GB DDR3
    1000 GB 7200 rpm Hard Drive
    17.3-Inch Screen, Nvidia GTX970M 3GB GDDR5
    Windows 8.1
    Or
    Acer Aspire V17 Nitro Black Edition VN7-791G-730V
    Intel Core i7-4720HQ Processor (2.6 GHz)
    16 GB DDR3 RAM
    1 TB 5400 rpm Hard Drive, 256 GB Solid-State Drive
    17.3-Inch Screen, NVIDIA GeForce GTX 860M
    Windows 8.1, 4-hour battery life
    Additionally, if you feel there is a better choice for $1500 or less, I would love to hear that advice as well.  I would really appreciate your help in making this decision.  Thanks!

    Of the 2 the Asus everyday. You won't notice the difference in the CPU's but you will more so with the GPU's as the 970 is a decent step up from the 860m. Add in extra SSD/HDD and RAM (I believe it goes up to 32GB but check), and see if they have allocated the 16GB as 2x8GB sticks or 4x4GB sticks.
    Other option I would suggest looking at a custom PC builder such as Cyberpower, Xotic or other (no affiliations, heck I don't even live in the same country). You will be able to get a much more tailored system with a better upgrade path within your budget. You will get better CPU, better GPU, RAM options up to 32GB and more flexible drive and msata combinations and most importantly some flexibility with the way the system is configured. Some are re-brands of popular gaming laptops, some are from the more custom line of chassis and some are just tweaked versions of your off the shelf names. Plus you don't have to crack the thing open to replace drives etc. that you are paying for but won't use due to slow speeds and the warranty implications that can come from doing this
    Not saying buy this as you need to shop around and find what suits you best but as an example this is from Xotic.

  • Adobe Creative Cloud and Adobe Creative Suite: New Choices for Customers

    Adobe has announced the new Cloud-based model for software distribution, along with new terms for boxed product upgrade eligibility. Beginning with the CS6 releases, when they happen, upgrade pricing on boxed products will only be availble one generation back. There is a limited window to upgrade now to the current versions at a discount.
    See http://blogs.adobe.com/conversations/2011/11/adobe-creative-cloud-and-adobe-creative-suite -new-choices-for-customers.html

    Eugene:
      Based on the current information we have (from the blog post), which may not be correct and which you should not rely upon:
    There is some confusion about the word "discount." As used in the blog post, in general there are no "discounts" for upgrades, there is the upgrade price and there is full price. But, also in the blog post, there is a special "discount upgrade" if you choose to upgrade to CS5.5 today (prior to Dec. 31, 2011), which is 20% off the regular upgrade. However, Peter used the word "discount" to distinguish between upgrade pricing and full price. It's probably a good idea to avoid using that word there because of the potential for confusion.
    I have CS5 InDesign in work. So I will be able to upgrade that to CS6 when it comes out at the discount price?
    You will be able to upgrade to CS6 at upgrade pricing. Not the 20% discount, but it is "discounted" from the full price of CS6.
    I'm still using CS2 Illustrator and Photoshop, for the little work I do in those programs, they're fine. But if I want to upgrade them to CS6 I have to pay the full amount of an upgrade, with no discount... or will I have to pay for CS6 in full for both of these programs?
    You will have to pay the full price (not the "full amount of an upgrade," whatever that means).
    If you elect to upgrade to CS5.5 prior to Dec. 31 of this year, however, then then you can pay the discounted upgrade price to upgrade to CS5.5 (well, CS5 since Photoshop CS5.5 doesn't exist), and then you can pay the CS6 upgrade price in March/April. So you can pay for no upgrades (full price) or two upgrades (one of which is 20% off).
    At the moment I can upgrade CS2, photoshop and Illustrator for €240 each, to CS5. So wouldn't I just be able to do that now and then buy the CS6 upgrade at a much later date perhaps just before CS7 comes out?
    Yes, you can do that.
    If CS6 has the tools to basically go "File>Export>Epub" and I get a fully working epub file without having to trash about in code afterwards or make complex tagging in InDesign, then I'll be buying it.
    It looks like EPUB is evolving pretty fast, so even if ID CS6 fully supports what you want out of EPUB on Day 1, I bet you'll need to be prepared to postprocess it on Day 2. Or at least long before Day 200.

  • Processor Upgrade for iMac G3

    Hello, I didn't see any particular posts specifically pertaining to the slot loading iMac (Graphite)..I hope someone can help me out.
    I have a G3 Graphite iMac, upgraded RAM currently running Tiger. I used to use it but wiped it clean, re-installied the OS and created a separate account for my 8y/o son, so essentially there aren't many apps on there. For some reason it's running slower than it should, even with just Safari open. Is there a fix or possibly a processor upgrade for this model (I keep seeing that there isn't, but I want to be sure).
    It's either that or constantly hearing my son complain of the lagtime and ask for our laptops instead...

    According to Mactracker at one point there was a 700 MHz model available in Graphite & Snow. If you could find a 700 MHz G3 CRT iMac logic board on eBay it might be possible to upgrade the processor speed. You could also install a Matshita SR-8184 or SR-8186 DVD-ROM drive.
    There's firmware available for both drives that allow them to be flashed to RPC1 or region free meaning they can play DVDs from any region in the world. Normally the drive is restricted to being able to only play Region 3 DVDs from the US. If you order a Matshita SR-8184CD optical drive from www.welovemacs.com call their 800 number listed on their website & be sure to ask for Jessica or Faith since some of the optical drives they sell don't have RPC1 firmware available for them.

  • How To create a message Choice for a page?

    Hi,
    I need to create a message choice for a page and on selection of that it should navigate me to next page..like
    ex:
    If iam havng 10 locations like Delhi,Hyderabad,Chennai....
    I need to select one of them and it should be navigated to next page based on the above selection...These values are to be retrieved from database...
    Can u gimme any idea..how to proceed?

    Maybe something like this will help.
    On your <af:selectOneChoice/> component configure a valueChangeListener and set autosubmit to true.
    In your valueChangeListener change the current view like :
    public void handleValueChanged(ValueChangeEvent valueChangeEvent) {
    // Add event code here...
    if (!PhaseId.INVOKE_APPLICATION.equals(valueChangeEvent.getPhaseId())) {
    valueChangeEvent.setPhaseId(PhaseId.INVOKE_APPLICATION);
    valueChangeEvent.queue();
    } else {
    // add additiional app functionality here
    ControllerContext controllerContext = ControllerContext.getInstance();
    ViewPortContext viewPortContext = controllerContext.getCurrentViewPort();
    viewPortContext.setViewId("test");
    Regards,
    Kenneth
    The deferred execution of ValueChangeEvent is necessary as the ViewID can only be changed in INVOKE_APPLICATION phase.

  • SCSI card for a G5 or processor upgrade for a G4?

    Hi all
    Actually, this is a question that concerns the G5 and the G4 forum, but I decided to post it here first.
    So, I have this old G4/400 PCI with an Adaptec 2930 SCSI card that I use for scanning slides with an Artix 4000t sclide scanner; this works fine, but the G4 is rather slow when it comes to using some features of the scanning software, such as removing scratches.
    I've been thinking about buying a SCSI card for my G5 (Dual 1.8) for some time now, but I'm not sure what card I should go for; I'm not even sure if there are still cards for such an "old" device as the slide scanner (about 3 to 4 years old, no Ultrawide or something like that). And then there's the problem of the drivers for the card - how long will they be available, especially now that Apple is switching to Intel...?
    The other possibility would be to buy a processor upgrade for the G4. I've seen some at OWC, and they seem to be less expensive than a SCSI card. The drawback of this solution is of course that I'll have to keep the G4 standing on my desk... on the other hand, I do know that the scanner will work perfectly with the G4.
    The G5, on the other hand... it will be faster and easier, since I won't have to transfer the files for storage and editing, I could free some space on my desk,... but will it work? The G5 is running 10.4, I'm not sure if my current scanner driver is compatible... and what when 10.5 comes out...?
    So I'm looking for a second, third, fourth... opinion:
    What would you do? Get a SCSI card for the G5 or a processor upgrade for the G4? What SCSI card would you recommend?
    TIA,
    Tina

    I've done some research on G5 and SCSI and scanners, and obviously, what I remembered was correct... making it work seems at least tricky, and maybe expensive too (if you've got to buy new scanning software and and..).
    So I guess that's decided: No SCSI on the G5. Leaves the question, should I buy a processor upgrade card for the G4? Getting some dual G4 on eBay might be an option, but then, that would be another computer in my already crammed office, and I just can't throw the G4 away, it's one of the very first models...
    I came by the idea of a processor upgrade because I just played around with an old Mac SE, which has an 68030 accelerator card installed, and this seems to work fine. Anyone has any experience with G3 /G4 upgrades (good or bad)?
    Smokerz: Why would you not recommend an upgrade? Any bad experiences?

  • Choices for free goods determination

    Hi all,
    I want to have choices for free goods determination, like for Material A I want an option to select either of Material A or B.
    Is this possible.
    regards,
    Vandana Arora

    hello, friend.
    it is possible to do this manually, and not through the free goods determination.
    let us say you want to give 1 unit of either material A or B for every 10 units of C ordered by the customer.  what you do is create a sales order for 10 units of C as the first line item.  let us further say the first line item is item 10.
    enter either A or B as the second line item, which is item 20.  go to the column HL Itm and enter 10.  also change the item category of this line item to TANN.  just be sure to maintain this set up in item category assignment in IMG.
    there are drawbacks to this procedure, in that your choices for free goods will not be limited to material A or B.  but this could work for you.
    you may also wish to create a BOM, wherein free good A can be replaced by B.
    regards.

  • What are the 3-bit field choices for Hw_Arm_Sel in PCI-6601

    Hi,
    I am programming our own driver to operate the PCI-6601. For our application we need hardware arm option. I know it is possible to use 2 counters for that, but NI-TIO should support also hw_arm. Although it is not explained in the registry document at all, after some tedious check in the DDK examples I found that this bits are located in the Gi counting mode register. I know the position of the HW_enable as well as the position of the 3 bits for pin sellect options. What I do not know is What are the 3-bit field choices for Hw_Arm_Sel . I contacted NI support but got no support. How can NI sell boards and when a customer who is not using LAbview or Measurement Studio or DDK, but is implementing his own driver is then so arrogantly turned down from NI? Also, how can NI publish just part of the registers the board support, and when a customer contacs and asks for some registers get not at all support? I can not foretell the missing registers, and it is pretty unprofessional to document just partly the registers of 660x devices. And on request you got nothing.
    I hope someone from the community know about this Hw_Arm_Sel 3 pin options. Otherwise, there is just an option of error and trial. Or simply throw the board in the garbage.
    Dr. Kirco Arsov
    Solved!
    Go to Solution.

    Hi Kirco,
    I have some more information for you :-)
    I haven't been able to speak to the developer who is the most familiar with TIO programming since he's out of the office, but I have come across his notes from when he was writing support for the DAQmx driver.
    As I described earlier, the HW_Arm_Sel bits don't select a connector I/O pin, but an internal trigger signal. There are seven internal trigger lines, and the HW_Arm_Sel bits map directly to the internal trigger signal: 0b000 - 0b111 map to 0d0 - 0d7. In order to route an I/O pin to an internal trigger, you must also write to a few more registers.
    From what I've read, there are two more register families that need to be programmed: TG_x_LevelEdgeReg and TG_x_CombinationReg, where x is the internal trigger number. In your case, you only need one pin from the I/O connector to be your arm start trigger, so TG_0_LevelEdgeReg and TB_0_CombinationReg will suffice for your application.
    TB_0_LevelEdgeReg :: Offset 0x660
    TG_0_LevelEdgeReg is only 8 bits wide, and maps as follows:
    7..6: EdgeMode
    5..0: LESel
    LESel selects the I/O connector pin to use as the source for the internal trigger signal. 0d0 - 0d39 will select the I/O pin of the same number. NB: behavior for TG_x_LevelEdgeReg is more limited for triggers 1-7, and only a small subset of the I/O pins can be selected for those trigger signals. Trigger 0 can use any I/O pin. Setting these bits to 0d63 forces the trigger source low, and can be used as a way to 'unroute' it when you're finished with your program.
    EdgeMode determines whether the TIO will detect an edge of the incoming signal, or just pass the signal level straight through. When detecting edges, it will latch the signal and generate a single TIMEBASE3 pulse instead. 0b00 sets level mode; 0b01 sets rising edge; 0b10 sets falling edge; 0b11 sets either edge.
    TG_0_CombinationReg :: Offset 0x6A0
    TG_0_CombinationReg is 32 bits wide, and has three fields of interest:
    19..16: CombFunction
    5..4: CombTypeB
    1..0: CombTypeA
    CombTypeA controls which trigger subsystem to use as the source for the trigger signal. Since you're coming from an I/O pin and using the edge/level subsystem, you must set these bits to 0b01.
    CombTypeB is similar to CombTypeA, and although you won't be using trigger B, set it to 0b01 to be safe.
    CombFunction performs a simple logic function on A and B. Since you're only using a single I/O connector, you only need the A output, so set these bits to 0b1100.
    All of the other bits should be set to 0b0.
    Unfortunately, I'm unable to test these statements since my test machine is currently being used for another research project. Please let me know what happens if you decide to test.

  • Question - is JavaMail the choice for me? Mass email delivery.

    Hello. I'm thinking about using JavaMail API, and I would like your feedback if JavaMail is the right choice for me.
    I'm working on a J2EE app (running on Glassfish) that will send email out to multiple recipients. The critical parts are
    1) It must scale so that it can send up to 10,000 email multiple times a day.
    2) The servlet that sends out the email must have a descent performance (can't hang while sending out 10,000 email forcing the user to wait, but for the servlet to send out 10,000 emails....I expect a little delay)
    So I'm using postfix for delivery with support for 10,000 recipients. I am thinking of using JavaMail inside a servlet which retrieves the 10,000 email addresses and creates 100 separate emails with 100 email recipients under BCC for each email.
    I am sending out the email in bulks of 100 separate email each with 100 recipients under BCC to address performance.
    Does my solution sound logical? Anything else I should be aware of?

    I'm not speaking from personal experience since I haven't tried to build something
    of the scale you're talking about, but...
    I wouldn't expect the overhead of the JavaMail API to be a significant issue here.
    Of course, you have to use the JavaMail API in a reasonable manner to get good
    performance and scalability.
    A lot depends on the performance of your server as well.
    I would expect the most difficult part to be handling the inevitable failures (network, server, etc.)
    that will occur when working at this scale.
    100 connections to your mail server several times a day shouldn't be an issue, but your
    mail server will be busy sending out all those messages.

  • What is the best Mac choice for creating pro-level art/graphics/animation?

    I'm an artist who does a lot of work with Adobe Creative Suite CS5, as well as some video editing and lots of animation. I've been using a 2007 model 15-inch Macbook Pro for the last 4 years, and it seems like it's time to upgrade...it runs burning hot all the time, and the battery dies pretty quick when the cord falls out. It seems like the whole thing is running a little slow, which is probably because I have a TON of graphics/animation/video software on there, but I need each and every program.
    My question is, what is the best new Mac to purchase to replace this one? I want to make sure it lasts as long as possible, and will be able to handle the programs I use now. My first thought is to get another Macbook Pro, because of the portability, and just add on all the higher RAM, etc to customize it. But my husband suggested looking into the Mac Mini, because it's a lot cheaper, and we're a little strapped for cash at the moment. Would that serve the purpose? Or is a Macbook Pro really the best choice for what I need it to do?
    I'd love to hear suggestions from other artists or graphics people. What do you recommend?

    For a "cash strapped" person, unless you already
    have a monitor, one of the new iMacs may be
    a better choice.  If you do have a monitor, I would
    suggest the dual core i7 equipt MacMini.  Since you state
    you are using CS5 stuff, most Adobe apps,
    Photoshop for example, do not make effective
    use of multiple cores.  Also, using any of the
    Adobe products, regardless of which computer
    you decide on, get as much RAM as you can afford.

  • Wrong choice for a monitor?

    Hi... just bought a samsung lcd tv monitor to hook up to my macbook pro, but I can't get good resolution for graphic design. selected highest res possible in s system preferences, but still sucky. Is it not a good choice for a  graphics monitor?

    TV monitors are usually never good for graphic design because they are designed to be viewed from across the room where the pixels merge when being viewed for a distance. So they tend to have bigger pixels and spaced more apart than computer monitors.
    Up close requires a higher pixel count per sq inch. So a 17" MacBook Pro has a like 1080i screen up close within a couple of feet as a 50" HD TV has the same at 20 feet.
    Since TV content is max at 1080i for 1980 x 1000 pixel count,  there is no need to make it bigger for up close and computer use.
    Graphic monitors of that larger caliper have something like 3000 x 2000 pixel resolution at 30 and 40" sizes to get the fine detail and less blurry type and images.
    If your looking for a larger screen for graphic design, I don't recommend Apple's glossy screens at all, look for a professional anti-glare high res models online.
    Apple has been slowly exiting certain markets that depended upon it's hardware in favor of serving only the consumer markets for gizmos.
    I fully expect the MacPro to go the way of the XServer in the coming years as demand slacks off for their "Pro" products.
    Apple is already introducing only integrated graphics in their "Pro" line of laptops and ineffective for serious professional use glossy displays.

    You're welcome. As to checking speed go to http://speedtest.net/ and it will choose the closest server for you. BTW, whatever you do, don't click on the robot icon that says "Start Scan" or MacKeeper below that. Only use the speed test in the middle that has the button BEGIN TEST on it. It will run a download speed test first and then an upload speed test. The download test will give a much faster response.

  • How can I get dock connector to turn off on air play. There is no longer a choice for sound to be displayed on iPad. I do not own outside speakers. Have already reset. Thanks

    Slow, intermittent.  Sometimes bootable sometime not. Odd behavior.
    Sounds to me like a classic case of your HD failing.
    Your SMART status may still show verified, with no errors on the Apple Hardware Test, Disk Utility shows no problems on Disk Repair-  this is of no help.
    I trust you have a good back-up and a bootable clone.
