• What motherboard for a Core i7 920 Processor?

  - by jasondavis

  I am wanting to build a really nice PC, price is not to important as I will buy pieces every week or whatever it takes until I get everything I need. I am not a gamer but I would like to watch video and have 3-4 monitors. I do a lot of programming and use a lot of big programs so I would like to go all out and get a lot of Memory, probably at least 12gb but possibly more even as I see many boards support up to 24gb now. Will be using Windows 7. I have decided to go with the Core i7 920 Processor BX80601920. Based on what I posted above, can you please recommend some good motherboards I should look at ? Also some good places to purchase them online. Thanks for any help, tips, etc.

• Extend university wifi network [migrated]

  - by asfasdoiuh ouhouhouh

  i live in a university campus and i can get wifi signal on the outside of my window but not in the house. The solution i use at the moment is a usb wifi dongle outside connected to my laptop but the lack of an internal antenna make the connection quite unreliable at times. So i was trying to find another solution to improve the reception of my network. One idea is to setup a router on the outside (in a place with stronger signal) and redirect the connection inside the house with an ethernet cable but the problem is that our Uni Wifi is managed by a capitve portal (BlueSocket with DNS redirection to login page) and the authentication has to happen on the mac address that connect to the net (so the client appliance in this case). If I use a router with Mac-Clone capability i will be able to be redirected trough the captive portal on my laptop computer and login from there or i need to setup my router to fill in the login page by itself? There are other hardware/software solutions i can use to get what i want? Thank you all

• Cannot get Virtual PC to install on my machine

  - by Brandon

  I'm not sure what I'm doing wrong. I ran the tool to check that hardware virtualization is enabled, and it is (i7-2600). I ran the proper version of the Virtual PC download (Windows 7 Professional x64) and I can see the Windows Virtual PC (KB958559) update in my installed updates list. The .msu file runs fine without errors, but even after multiple reboots I can't actually find a trace of Virtual PC anywhere. There is nothing in program files, the start menu, or system32. Am I missing a step?

• How's the latency with Mac VNC on Windows PC using a crossover cable?

  - by Vadoff

  I use a Windows 8 PC as my main system, and do some programming with Xcode which I use a virtual machine for. However, it doesn't run as smoothly as I would like, so I'm thinking about purchasing a Mac Mini. My question is if I connect my PC to the Mac Mini directly (via crossover cable, firewire, or usb), would I be able to control the Mac using VNC with almost no latency? If not, is there any other way I'd be able to use both my PC and the Mac Mini simultaneously (using the same peripherals)?

• Help looking before I leap! I need expert guidance...

  - by Ellen Reddick

  27" iMac running win7 under bootcamp (slick! ). I have Access 2003 program with files linked through ODBC used by 4 installations (all with Access 2003 installed). I want to buy Access 2010 and try it under virtual PC (under Bootcamp). Will it work (since I have to install the ODBC drivers)? If I decide after this trial that I like what it does, can I then install it under the Windows 7 bootcamp partition (with or without uninstalling the virtual PC) without using up the 2nd allowed installation? Also, I see that MS allows an Office Pro 2010 trial download good for 60 days. Would this work in Windows 7 Virtual PC and would it be a better way to go, followed by a legitimate purchase of Access 2010 for the Windows 7? This is not an Access programming question--I realize there may be some tweaks necessary in the program to run it under 2010 and I can handle that part.

• Monitor has yellow tint when used with the graphics card

  - by artknish

  I have an nVIDIA graphics card when used produces an yellow tint on my monitor's display. I tried with another monitor and it had the same issue. I then switched back to my motherboard's inbuilt graphics output (not sure what the technical term is), and the display seems fine, except I can't get the optimal resolution of 1440x900 to work. So is my graphics card's life over? Or can I get it repaired? Any self remedies without calling a hardware guy? Should I try with a DVI cable? I've been using the VGA cable from my graphics card to the monitor so far. Thanks for your suggestions!

• What do you do with a 15 node decommissioned Itanium cluster?

  - by Gomibushi

  We are decommissioning a 15 node Itanium cluster. We don't know what to do with it. Being geeks we want to put it (or its individual nodes) to some cool use, but since it is Itanium we are a bit unsure what that could/would be. We are not bringing it back as production servers and we are considering giving them away, if anyone wants them. It's not the most spiffy hardware, but being 2U rack servers they pack an ok amount of cpu and memory, they're about 3 years old perhaps. Ideas to what runs well on them? Or something one can use them as?

• Can't install CUDA drivers for GeForce GT555M

  - by saeed

  I've just bought a new Asus n55 laptop. It has 2 graphics cards from Intel and NVIDIA. But when I try to install CUDA's developer driver for my GPU I get this error: "This graphics driver could not find compatible graphics hardware". I have downloaded both of the following files but both of them get mentioned error: Developer Drivers for WinVista and Win7 (270.81) Notebook Developer Drivers for WinVista and Win7 (275.33) How can I fix this problem? Actually how can I develop CUDA programs on my NVIDIA GPU?

• Using VMware's ESXi, can I plug in 30 USB Wireless adapters and allow each of 30 VMs one?

  - by 31eee384

  I'm assuming ESXi will act very similarly to VMware Workstation or other products, so answers based on knowledge of those programs might also help. I want to plug in 30 USB Wireless or Ethernet adapters into my server, and let each VM access one and only one of these devices. Unfortunately, I don't have the hardware to just try it out as the purchase of hubs and adapters hinges on the result of this question. The answer could be a resounding "yes, easy!" and that would be great. I couldn't find any answers to this question with google, and it's possible that this is because it's so easy to do.

• How can I disable my laptop's built-in keyboard?

  - by sam

  I have a HP Compaq Presario C700 laptop with Windows 7 installed on it. My laptop's keyboard is not working properly; some keys never work and some keys will keep on pressing. I've formatted the OS but it didn't solve my problem. I bought an external USB keyboard and it works well. As some keys in the built-in keyboard activate themselves, I still couldn't work effectively. After searching Google I tried the following steps to disable the built-in keyboard: Disabled keyboard drivers: This didn't work because when the system reboots, the driver gets installed again automatically. Installed irrelevant driver for keyboard: This failed - I couldn't install the driver. After rebooting it installed the correct driver automatically. Can anyone help explain how I can temporarily uninstall my built-in keyboard? I don't want to remove it manually (removing the hardware cable).

• **Simplest** way to dual boot Linux on a Vista laptop

  - by user20285

  I have a 64bit Vista laptop with no cd drive (and no intention of buying one). What is the simplest way (if any) for me to dual boot Linux (I don't care what version as long as it's not too old...and will run Ruby 1.8.7 or greater)? I'd prefer anything with an installer. I've been programming on Windows for a little over 1.5 years and would like the option of using Linux. I'm not a moron, but the I'm legitimately scared of messing up my computer. I speak the language of Rails, not of OS tweaks. Thanks!

• Fastest OS for Java applications

  - by user33408

  Hello I have a multithreaded Java program. I am dealing with certain perfomance problems. I have improved everything. Hardware + Software. Now I think that it's time to move to proper Operating System. I was wondering, what OS is the fastest for Java Virtual machine? I am using Sun Java6. Do you think that Sun Solaris would be the best choice for Java applications? Or FreeBSD? or CentOS (I am using it currently)? Thanks

• Options to Reformat USB Drive

  - by user8783

  I have a 64GB usb thumb drive. When I plug it into a Windows system (I have tried several machines with both Windows 7 and 8), the system attempts to read it and never completes. The drive does not show up in the device manager, nor does it appear in Computer Management - Disk Management. If I click on the "Safely Remove Hardware" icon, however, I do get an option for "Eject Mass Storage Media", although it never accomplishes anything. Also, as long as the USB drive is connected, I cannot access other USB drives or even restart my computer. It seems as though it locks up Windows Explorer. Is there any option to reformat this drive? It was a great drive up until all this craziness began and I would hate to throw it out because it was rather pricey.

• Windows 7 on 1st Gen MacbookPro Unibody (Q4-2008) - power problems.

  - by typemismatch

  I have the first generation macbook pro, purchased Q4 2008. I've been trying to run Windows 7 and can get it all installed great with the BootCamp 3.1 64 bit drivers however ... power management isn't great. The screen and keyboard don't automatically dim - the laptop gets too hot. I noticed on some newer macbook pros that windows 7 works perfectly and the above doesn't happen. Does anyone know if there really is a hardware issue with this 1st gen or is there some firmware update I can use to fix this? Thanks!

• Windows XP - non-user input data filter message after installing wireless keyboard & mouse

  - by James

  After I installed MS wireless keyboard and mouse and associated software, I started getting this annoying message titled "Hardware installation" telling me the software I am trying to install did not pass the XP logo tests. The software is for "HID non-user input data filter" and I have two options Continue anyway or stop installation. Now, if I try to continue the installation fails, if stop installing another message pops up with a little mouse logo and the whole process repeats itself. after I am done with that message a third dialog appears. This is happening every time I boot up my PC (a desktop), I tried following an advice I found in some forum and download windows update for ID non-user input data filter, but that installation failed as well. The thing is, that both keyboard and mouse are working fine Is there anyway to get past these dialogs ?

• Search for specific call in asterisk log files

  - by chiborg

  In my Asterisk log file, I have a line like this (truncated): Executing [123@mycontext:1] Set("SIP/myhost-b7111840", "__INCOMINGCLI=4711") Now I want to do the following filtering while looking at the log file with tail -f: Match lines with a specific value for "INCOMINGCLI", storing the call ID (the "SIP/myhost-b7111840" part) Output all subsequent lines that contain the call ID. As a bonus, having a grep-like option like -A would be nice. I could do that easily in various programming languages, but how would I do it with standard UNIX commands like sed or awk? Can it be done with these commands?

• Iozone: sensible settings for a server with lots of RAM

  - by Frank Brenner

  I have just acquired a server with: 2x quadcore Xeons 48G ECC RAM 5x 160GB SSDs on an LSI 9260-8i Before deploying the target platform, I'd like to collect as much benchmark data as possible, testing I/O with hardware RAID in various configurations, ZFS zRAID, as well as I/O performance on vSphere and with KVM virtualization. In order to see real disk I/O performance without cache effects, I tried running Iozone with a maximum file of more than twice the physical RAM as recommended in the documentation, so: iozone -a -g100G However, as one might expect, this takes far too long to be practicable. (I stopped the run after seven hours..) I'd like to reduce the range of record and file sizes to values that might reflect realistic performance for an application server, hopefully getting the run times to under an hour or so. Any ideas? Thanks.

• Please define: "Maximum Memory Supported - 10GB, Service Upgradable Only"

  - by Droogans

  I am assuming this means that the RAM modules can only be inserted/removed from some place very inconvenient? Maybe under the keyboard? Or does this mean something more strict, as in the only way to get an upgraded module in the laptop is via some special toolset, or verified through the hardware to allow the system to recognize the new memory? I ask because I'd want to know if I need to buy my own additional RAM, since I can't seem to find a way to get to 8GB. A Google search result turned up very little other than hits for shopping. Here is the laptop in question: http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=4817549&sku=T78-144301

• What SATA drive should I install FreeBSD onto? i.e. ar0 vs da0 vs ad4/5

  - by Matt

  I'm installing FreeBSD 8.0 on a server that has hardware SATA Raid. I'm just wondering. What is the difference between these devices. i.e. ar0, da0, ad4, ad5 I take it that ad4 & 5 are my two disks. Somehow the OS can see them individually even though it's one logical mirrored drive. Should I be installing it onto ar0 or one of the adX disks. What is da0? it's smaller than the others. ar0 is not some kind of software raid device is it? Just want to make sure I don't mess this up right from the get go.

• Soft links between samba profile and profile.V2

  - by Alex Rose

  I am currently using a samba server to host windows sessions. For the moment, every machine runs windows XP, but in an upcoming hardware upgrade, I will have new Windows 7 machines installed. The problem is that the user directory changed from XP to 7 (for instance 'My Documents' became 'Documents'). To solve that, samba created a folder called profile.V2, which contains files and folders for Windows 7. Now I would like to link the two profiles folders ('profile' from windows XP, 'profile.V2' from windows 7) so that a user can logon from a XP or 7 machine and still have access to the same files. I tried to create softlinks between folder pairs ('Documents' -­­ 'My documents') and it seems to work. My question is : is it likely to create issues in the future?

• Google Chrome Automatically Save Passwords

  - by benhc911

  I have seen, and at one point implemented, methods of modifying firefox's password manager popup such that it would automatically save usernames and passwords without prompt. I was wondering if there is a similar feature for Chrome. I just recently switched to chrome and it is one of a few features/modifications that didnt survive the transition, and while I am moderately capable in programming in certain languages (C+, visual etc) I don't really feel confident enough to muck around unguided. For anyone that is particularly interested, the other features I miss are things such as the slash based 'quick search' in firefox... and I am currently annoyed by a different right click menu order for opening in new tabs and new windows (the reverse of firefox). Any help would be greatly appreciated!

• Will this RAM work well in an iMac?

  - by sala_7

  I want to increase the RAM of my 2.4GHz Intel Core 2 Duo 24" iMac. I currently have 1GB of RAM DDR2 SDRAM 667 MHz. I really want to upgrade, but know nothing about RAM or hardware in general... These are the cards I found: http://www.crucial.com/eu/store/mpartspecs.aspx?mtbpoid=D4B6F603A5CA7304 Are these of quality or should I look at something else? Finally, I have 800MHz of Bus speed, couldn't I get faster RAM? Thanks for taking the time to read, and hoping you take the time to answer.

• How to achieve redundancy across data centers?

  - by BrandonBT

  I have a LAMP server with a lot of hardware redundancy built in. I am not worried about the server becoming unavailable. What I am worried about, however, are potential network issues in the data center the server is in. What I would like to have is another server in another data center for redundancy. Load balancing is less of a concern. With that said, I am relatively clueless on two points: How to have two servers in two geographically separate data centers that have exactly the same data, in terms of both files and MySQL databases. How to ensure that all traffic coming into one data center are automatically transferred to the other database in the case of a network or server failure at the first data center. Any guidance on how to accomplish the above two problems would be greatly appreciated.

• Installing Solaris 10 on sunT5220 - ZFS/UFS raid 10?

  - by Matthew

  I am in a bit of a time crunch, and need to get two T5220's built. We were very happy to see two boxes in our aged inventory which had 8 HDD's each, but didn't think to check if they were running hardware RAID or not. Turns out that they aren't. When we install, we are given the option to use UFS or ZFS, but when we select a place to install we're only given the option of installing on one single disk. Is it possible to create a software raid 10 across all of the disks and install the OS on that? Sorry if any lingo is wrong, I'm not really a Sun guy and our guru is out of town right now. Any help would be really appreciated! Note: Most of the guides I've found on google entail installing the OS on a single disk, and then creating a separate RAID 10 on other disks. We would actually like the OS to reside on the RAID 10. Hope that clarifies things.

• bad switchs duplicate my ip

  - by tacoen

  I had a large area LAN. There were many switch and AP on it, then somehow I couldn't ping my servers, and it's said that the IP was duplicated. I use arpwatch and found out that one of the switch flip-flop-ing the IP. I isolated that troublesome switch using his mac-address. But, since this a large area LAN... I doubt this will be the last cases. If there any software or hardware that I can use to prevent this kind of error? Sorry for my bad English.
