  • what are the rules for SLI ( GTX 550 Ti )

    - by equivalent8
    I got ASUS GTX 550 Ti and I want to SLI it with another graphic card. I heard that not all graphic cards are good idea to SLI, (or not all combinations) because sometimes the final performance could be even worse that with one graphic card. Is that true? What are the rules ? ( maybe chip-set needs to be same or something ? ) I was wondering if you can recommend me what Graphic card should I use as with mine. Should I use same one (GTX 550 Ti) ?

  • Does a modern PC require a graphics card to run?

    - by ArtM
    As I can remember, on old systems (Pentium II or III) it was not possible to boot and run the PC if the graphics card was missing (AGP cards were used in those days). Many years from then, I'm using motherboards with integrated graphics and I have no experience related to this subject, the "graphics card" always was present. Currently I intend to build a home/private "server" for my purposes and most of the motherboards I want to buy have no integrated graphics (AMD 870 or 970). I can take a normal graphics card from my firends for a few hours/days and use it when installing the necessary software. The question is: can I boot and run the PC without problems after I install everything I need and the graphics card is removed? if a general answer cannot be given, at least some examples of manufacturers/MB series/MB models will be helpfull I think it's obvious, but for completeness: I mean cheap desktop components, not real servers.

  • How do I listen to my microphone through my speakers in Windows 7?

    - by Gray Adams
    I've looked about and before you say it: I've used the "Listen to this device" feature built into Windows. The issue is that it is a USB microphone and there is a second delay before when it plays on the speakers, literally making me go quiet because my brain doesn't work too well hearing myself a second after I say something. I use Realtek Audio, so it works differently from the monopolistic Creative sound cards. There is no "What U Hear" or "Line In" levels. It's just "Speakers" and "Microphone". Is there a software I can use that will not have delay? I want to wear nice headphones and still hear myself

  • Graphics card for dual 2560 x 1440 output

    - by Bender
    As the title suggests I want to power two 2560 x 1440 monitors from one graphics card. I am just about to send my second graphics card back to Amazon, so before I purchase a 3rd incorrect card I thought I should get some advice. My latest card has dual DL-DVI output but only supports 2560 x 1440 on one output, the other maxes out at 1920 x 1080. Can graphics cards with two Dual Link DVI adapters (or alternately, one Dual Link DVI and one DisplayPort support the a full 2560 x 1440 on both monitors, or does that depend on the graphics hardware and not only the connectors?

  • use correct-resolution background desktop image

    - by Rob Bos
    I have a desktop background image (a picture) in a half-dozen different resolutions, that I'd like to deploy to a disparate collection of computers with different monitors and video cards and whatnot. Laptops, netbooks, desktops, widescreen, and even a couple of "tall" screens. I have images to cover most of the cases. I would like Windows 7 to correctly pick the correct desktop background image via group policy. Now, the logon screen is already done. The OEMBackground method is rather clever, and lets you copy files of different resolutions to the machine, and the logon app will calculate the aspect ratio of the monitor and match it to a file as closely as possible. Is there any way to have that functionality on the desktop background as well?

  • UVC device Logitech WebCam 9000 pro

    - by Pavel
    There is such a good webcam in universe that acts as a "USB Video Class" (UVC - video USB standart interface) - the logitech webcam 9000. UVC offer unified interface allowing to control it or grab a picture from it by any UVC-driver. You need one universal driver and you support all the UVC devices (webcams, video-cameras, video-grabbing-cards etc). For example, in linux - if you have UVC driver - you don't need to think about specific webcam driver for UVC webcam. UVC has unified way that webcam transmit its awailable resolutions and other capabilities, so i see 1600x1200 resolution without any problem. I wonder if windows 7 has UVC. I mean "universal UVC" (-; It says "USB Video Class", but doesn't give resolutions larger than 640x480 and webcam's controls, like 'sharpness', 'focus' and other as linux's driver does...

  • how to monitor traffic at port 53 (DNS)

    - by Registered User
    I am a bit confused with the abundant tcpdump tutorials on internet. I am having a few of the virtual machines running on a virtualization server.Where I am debugging a problem.Port 53 is the one in problem. I have a bridged setup where out of 4 LAN cards on the machine in question one is active and it is xen-br0 I want to check if there is any request coming on port 53 on the server by other machines on LAN in question. I also want to see if the guest operating systems on LAN or any other machine is sending traffic at port 53.Due to abundant messages being generated via tcpdump I am finding it difficult to grep the output at desired port. So how can I use it if some one can give an example that would be helpful. Thanks in advance.

  • Gigabit connection between 2 computers

    - by Alecu
    I am trying to set up a connection between 2 pc's. It's a direct cable connection. The problem that I am having is that the connection isn't gigabit. I know both network cards support gigabit. I checked in the device settings and in one pc I can see in the Speed & Duplex the 1Gbps option but on the other pc I can't see that option despite the fact that the network card is gigabit. I have quite some files to copy from one pc onto another and I really need a good connection between them. I can't really remove the hard drive because it would void the warranty. Could this be a driver issue or a cable issue? On both pc's I have windows 8. The network card on the pc that doesn't have the 1 gbps option is an Atheros ar8161 card.

  • Recommendation for hardware upgrade: thin clients? Or...?

    - by Alex C.
    I work for an animal shelter in Upstate New York. We have about 50 machines running XP Pro. They're connected to a Windows network with a domain. About half of these computers are used for nothing more than using two web-based apps -- one to keep track of our animals, the other to process credit cards. Having a full-blown desktop PC seems like overkill for this purpose. The PCs are three-to-five years old, and I'd like to come up with a plan to upgrade the hardware. Our donations are down (not surprising, given the economy), so cost is a big factor. Can people recommend some options? Some sort of thin client, maybe?

So I am not able to test my externally usb connected wifi adapter. Can anyone suggest me way to disable eth1 interface?

  • How can I watch full size video on 1 monitor and work on another?

    - by jasondavis
    Here is my situation. I have 3 monitors hooked up to my new PC running off 2 video cards. When I watch a video on one of the monitors and make it go full screen on that monitor it is great, however as soon as I click anywhere on one of the other 2 monitors, it makes me lose the full screen mode of the video and makes it go back to it's original size. This happens when watching a flash or silverlight based video in Google chrome as well as when I watch video from a player such as iTunes. Is it possible to make a video play fullscreen on one of my monitors and still work in the other two screens without loosing my full screen mode on the one monitor?

  • Program for managing multiple monitors to keep from rearranging Windows

    - by Rumel
    I have a setup in use where I use up to four monitors. The problem is I generally switch around what I'm using and that messes up where all of my windows are. I'm on Windows 8 and have two graphics cards. My setup is as follows: Monitor 1: Card 1 Monitor 2: Card 1 Monitor 3: Card 2 TV 1: Card 2 I almost always have all the monitors turned on and in use. When I turn on the TV though, all of my windows get reconfigured and moved to different monitors. I don't know how to stop this. Another configuration I use is where I have Monitors 1 and 2 plus TV in use, and I have my Xbox in use on Monitor 3. When I get done with the Xbox and switch Monitor 3 over to the PC, everything is reconfigured. So is there a program out there that can help with this? I have the free version of Display Fusion in use but haven't seen settings to save monitor configurations.

  • One motherboard crashed. Changed and wants to crash again

    - by CoachNono
    My computer started to freeze randomly. I was pretty sure it was the hard drive that was starting to fail. Before I could change it, the motherboard was completely dead. I bought the same one and reinstall it. Everything went working well until my computer started to freeze again and doing the same problem has before. I don't want my motherboard to burn again and I'm really wondering what can be the problem... Could it be the power supply or the video cards that burned the motherboard ? I tested the voltages of the power supply and they seemed fine... The computer worked as is for four years... Here are the specs: ASUS P5N-D Motherboard LGA 775 NVIDIA 750i SLI Intel Q6600 2X EN9600GT 512mb 650w Corsair

  • network configuration

    - by carlcroom
    Hello all. I have just inherited a network at my work- 1 primary server and about 65 computers running XP. All machines have Gigabit ethernet cards and all are connected through Gigabit switches and cat. 6 cables. The workstations send large numbers of image files to the server where they are held until they need to go to a printer. And I'm talking Gigs of files. We get a network slowdown when large number of files are coming from the workstations at the same time large numbers are also going the the printers. All machines have to be on the same subnet because of some proprietary software. Is there anything I can do to lessen this logjam? Any help would be greatly appreciated.

  • Remote Desktop Multi Monitor Connection

    - by user196039
    This question may be a bit unusual but I think it's an interesting angle: Why does a remote desktop connection to my server with all four of my 30 inch (@2560x1600) monitors work, even though the server doesn't have a graphics card installed? I guess the graphics are perhaps not really rendered on the server? What exactly happens there so that this works? Searching for this I mostly found "how to enable multi monitor support" but not an answer to my question yet. Any links/documentation I can read to understand this better? (To get all four monitors working well on my local machine the one graphics card I had wasn't even enough, so I have two graphics cards on the local machine now) The operating systems are Windows 7 home premium and it's a Windows Server 2008 R2.

  • Will a `wireless n` network adapter work `wireless g` router?

    - by ShoeLace1291
    I have verizon fios internet service. I believe they use a Wireless G router, but I just have one question. I currently am using a 54mbps wireless pci adapter in my Windows 7 custom build. It drops the internet connection all the time and is starting to get very irritating. I'm thinking about buying a new one, but all the 300mbps cards on newegg are wireless n. So my question is, will a wireless n network adapter make a difference with a wireless g router?

  • ID Badge Access System for Building with Active Directory Integration [closed]

    - by Alex
    I hope this is the right place for this question. So, we're looking into setting up a building access that uses badges or cards of some kind. I wanted to ask the users on here if they've had to do such setups and/or if they have recommendations? Is there maybe a system that integrates with Active Directory? I know one of the things our managers want to do is to be able to run reports on when people are entering the buildings. I'd appreciate any suggestions and thanks in advance!

  • What could slow Excel on one PC but not another?

    - by zrz
    I have 2 PC with the same configuration. I open an Excel File (~5M) on the network from both PC. The opening is not the fastest but that's ok. The problem is that on one PC, Excel is really slow. I mean if I hit the left arrow 10 times, I will have finished hitting like 3 seconds before the active cell is the next 10th one. The file contains graphics that takes time to initialize on the slowed computer. Both PC have the same graphic cards, same driver version; both remote access to the file on a local network. Both configured to perform calculations automatically. Both Excel 2007. Both Windows 32bit. On the other PC it runs really fast. I really don't know what to check next. Any suggestions ?

  • Multiple monitors (3) in notebook using HDMI and vga port, with a graphic card only.

    - by user34427
    I have a HP dv9830us laptop. It has a vga-out and a hdmi-out port. I want to know if it's possible to use 3 devices, each one with different displays, using just one graphic card - NVIDIA GeForce 8600M GS? (Original, vga with an external monitor and hdmi with a full hd tv). Where I can find this kind of information? If not possible, I would like to know alternatives like: "Usb" solutions to be possible to connect to the external lcd or to a TV. The TV should be flawless, but the second monitor can have slow response times; Cheap PCMCIA video cards to be possible to connect to an external monitor, so I would use the hdmi with the tv and this second video card to output to another monitor. I'm using Windows 7 and Ubuntu 10.04. Is this possible in both systems?

  • Radix Sort in Python [on hold]

    - by Steven Ramsey
    I could use some help. How would you write a program in python that implements a radix sort? Here is some info: A radix sort for base 10 integers is a based on sorting punch cards, but it turns out the sort is very ecient. The sort utilizes a main bin and 10 digit bins. Each bin acts like a queue and maintains its values in the order they arrive. The algorithm begins by placing each number in the main bin. Then it considers the ones digit for each value. The rst value is removed and placed in the digit bin corresponding to the ones digit. For example, 534 is placed in digit bin 4 and 662 is placed in the digit bin 2. Once all the values in the main bin are placed in the corresponding digit bin for ones, the values are collected from bin 0 to bin 9 (in that order) and placed back in the main bin. The process continues with the tens digit, the hundreds, and so on. After the last digit is processed, the main bin contains the values in order. Use randint, found in random, to create random integers from 1 to 100000. Use a list comphrension to create a list of varying sizes (10, 100, 1000, 10000, etc.). To use indexing to access the digits rst convert the integer to a string. For this sort to work, all numbers must have the same number of digits. To zero pad integers with leading zeros, use the string method str.zfill(). Once main bin is sorted, convert the strings back to integers. I'm not sure how to start this, Any help is appreciated. Thank you.

  • SFML: Generate a background image

    - by BlackMamba
    I want to generate a background, which is used in the game, on every instance of the game based on certain conditions. To do so, I'm using a sf::RenderTexture and a sf::Texture like this: sf::RenderTexture image; std::vector<sf::Texture> textures; sf::Texture texture; // instantiating the vector of textures and the image not shown here for (int i = 0; i < certainSize; ++i) { if(certainContition) { texture.setTexture("file"); texture.setPosition(pos1, pos2); } else { ... } image.draw(texture); } The point here is that I draw single textures on a sf::RenderTexture, but because textures always are on the graphic cards memory, I can't exceed a certain map size which I have to. I also considered using an sf::Image, but I can't find a way to draw an image (i.e. a texture) to it. The third way I found was using an sf::VertexArray, but this seems to be a bit too low-level for my rather simple purposes. So is there a common way to dynamically generate a background image based on other existing images?

  • Sun Storage 2500-M2 Array and Sun Fire X4470 M2 Server

    - by nospam(at)example.com (Joerg Moellenkamp)
    There is some new hardware in the Oracle portfolio. The first one is the Sun Fire X4470 M2 Server. There was a lot of talk about the system before because of benchmark results, but now it's finally announced. Two or four Intel Xeon E7-4800. Up to 1 TB as the system provides 64 DIMM slots with 16 GB DDR DIMMs. The memory is placed on those riser cards right behind the fans of this chassis. Up to 6 internal drives. In a 3 RU package. Another announcement was the Sun Storage 2500 M2 announced yesterday: From 5 to 48 drives (the later number with three expansion trays) for up to 28.8 TB of storage. The array is SAS based internally. You can put 300GB and 600 GB in it. The 2540-M2 provides 4 (8 optional) FC ports with up to 8 GB/sec. The 2530-M2 has 4 SAS2 ports with up to 6 GBit/s. It has 2 integrated controllers providing 2 GB cache protected by a power backup for 72 hours. The controller enables the arrays to deliver 0, 1, 10, 3, 5, 6, (P+Q) RAID levels.

  • importing a VCard in the address book , objective C [migrated]

    - by user1044771
    I am designing a QR code reader, and it needs to detect and import contact cards in vCard format. is there a way to add the card data to the system Address Book directly, or do I need to parse the vCard myself and add each field individually? I will be getting the VCArd in a NSString format I tried the code below (from a different post) and didn't work -(IBAction)saveContacts{ NSString *vCardString = @"vCardDataHere"; CFDataRef vCardData = (__bridge_retained CFDataRef)[vCardString dataUsingEncoding:NSUTF8StringEncoding]; ABAddressBookRef book = ABAddressBookCreate(); ABRecordRef defaultSource = ABAddressBookCopyDefaultSource(book); CFArrayRef vCardPeople = ABPersonCreatePeopleInSourceWithVCardRepresentation(defaultSource, vCardData); for (CFIndex index = 0; index < CFArrayGetCount(vCardPeople); index++) { ABRecordRef person = CFArrayGetValueAtIndex(vCardPeople, index); ABAddressBookAddRecord(book, person, NULL); CFRelease(person); } CFRelease(vCardPeople); CFRelease(defaultSource); ABAddressBookSave(book, NULL); CFRelease(book); } I have searched a bit and fixed the code and here how it looks like it doesn t crash anymore but it doesn t save the VCard (NSString format) in the address book , any clues ?
