  • Intel® Core™2 Duo Desktop Processor vs Intel® Core™ i3 Desktop Processor?

    - by metal gear solid
    Intel® Core™2 Duo Desktop Processor vs Intel® Core™ i3 Desktop Processor? Which CPU is better to buy ? Intel® Core™ i3-530 Processor (4M Cache, 2.93 GHz) (it supports DDR3 also) or Intel® Core™2 Duo Processor E7500 (3M Cache, 2.93 GHz, 1066 MHz FSB) (it supports DDR2 only ) Although I do not play games on my PC but I need good performance in Adobe Photoshop, Watching Full HD Movies. I need good performance in Multitasking. Along with any of these CPU I would purchase 2 GB x 2 stick of RAM. and I will use Windows 7. and I will use Microsoft VPC images also with MS Virtual PC.

  • Upgrading a PERC h310 to a PERC H710 mini RAID controller on a Dell R620

    - by Gregg Leventhal
    I have an ESXi 5.0 Free license host using an internal Datastore (RAID 5, 5 Disk) that was configured with a Dell PERC h310 RAID controller. The disk performance was very poor, so I upgraded to the PERC H710 Mini. The IT Tech installed the controller and powered the host back on. I had to rescan the controller and the datastore appeared. Should any settings be changed in the RAID BIOS, or should the default settings be sufficient? Is they anything to be aware of when performing this type of upgrade in order to achieve the maximum performance?

  • Buying replacement Macbook Pro Battery - Genuine vs. eBay

    - by Nicolas Webb
    I'm looking to replace my Macbook Pro's battery (15", last model before the Unibody). It's currently at 55% capacity (as reported in System Information and Battery Health Monitor). I've reset the SMC firmware, calibrated the battery, and it's just not lasting that long anymore. I've seen some genuine replacements that are "pulls" (pulled from used computers) that are rated at least 90% capacity (iFixit, MacSales). I've also seen a variety of batteries on eBay that look more like clones than genuine batteries, but are new. A new battery from Apple is $129, and when I brought my laptop in they ran the Battery test and said if I bought the battery right then they'd give me a discount (around $100). Anyone out there used one of these "OEM Compatible" batteries? Fit/finish good? (I don't want a funky color or a corner that sticks out.) Or, should I just suck it up and get the genuine replacement (for about twice the price)?

  • Which part of the computer needs all the power from the PSU?

    - by Xeoncross
    A couple years ago I was building a new Core 2 Quad system and after reading all the reviews was convinced that I would need at least a 400 watt power supply unit (PSU). I bought a 500W Antec EarthWatts However, last year I bought a Kill-A-Watt power meter to test some things around our house and found that my PC was only using 80W of power while idle! (C2Q, 4GB RAM, SATA HD, & DVD burner) Well, here I am building another computer with a 65watt Core 2 CPU in it and I'm wondering if I can skimp out this time and get a 300watt or so unit since my usage doesn't seem to be what everyone claims it is. I'm sure that the people in the reviews who exhausted 500watt PSU weren't lying - so what is it that uses all that? The high-end dual SLI video cards? Lots of SATA drives? Overclocking?

  • Dell Poweredge 2650 RAM Upgrade

    - by Vik
    Hi, I bought an old Dell Poweredge 2650 off ebay to use as a dev server, but I need to get more RAM for it. From what I understand there were 2 versions of the 2650 released, with the older version only supporting PC1600 RAM (200MHz) and the 2nd version supporting PC2400. Unfortunately Dell thought it wasn't necessary to label their servers as such so I can't tell what version I have. Does anyone know if there is a way to tell without buying and testing RAM in the server?

  • What exactly is a Mobile mouse? + Mouse Recommendation

    - by chobo2
    I am really disappointed with Logitech. My first cordless wireless mouse was from them and it lasted like 5 years. So I decided to get another one from them http://www.futureshop.ca/catalog/proddetail.asp?logon=&langid=EN&sku_id=0665000FS10099373&catid= And this mouse sucks bad. After 6 months it broke. I returned it under warranty and got a new one now 4-6 month later it is on the verge of breaking again.... You pay like $50 for this mouse and it lasts like 6 months that sad. I just lost faith in Logitech mice as I remember my bro also had a logitech mouse too and it broke after like 6 months. He then bought another logitech mouse(different model) that has been working for maybe 2 years(and no signs of breaking) but I am not crazy about the mouse(I don't like the 2 buttons by the wheel) and I not sure if they even sell it(maybe they got rid of it because it lasts too long). http://www.tigerdirect.ca/applications/SearchTools/item-details.asp?EdpNo=1578495&CatId=1285 So I am looking at a Microsoft mouse. http://www.futureshop.ca/catalog/proddetail.asp?logon=&langid=EN&sku_id=0665000FS10125565&catid= I am looking at this one but I am not sure what they mean by mobile mouse. I think that is what MS calls notebook mice. So I am not sure if this would be a good mouse to get for a desktop. I see it uses like a micro usb receiver but I am not sure if it is smaller then a standard mouse. But almost all the mice I looked at at futureshop.ca or staples are labeled notebook mice or mobile mice. So not sure what mice would be right for me. I don't want a corded one though. I really liked the LX6 design alot but it can't last more than 6 months. Thanks

  • Desktop SATA drives in SATA <-> FC array

    - by chris
    Let's assume you've got a box like one of these with space for 24 SATA disks. What are the best bits of advice for deploying this? For instance, should you be greedy and go for the 1.5 or 2tb disks or are they just not reliable enough to be used in an array like this and you should stick with 640gb or 750gb disks instead? Also, I know that FC (or generically, "enterprise class") disks have a different error recovery strategy than desktop disks. An enterprise disk will fail a read quickly and report to the controller that it wasn't able to read that block, and the RAID controller will quickly regenerate the info from the parity disk and mark the block as bad. A desktop disk, on the other hand, will try and try and try again to get the data, and in pathological cases this may cause a raid controller to fail the whole disk because the read operation times out. So there are a couple aspects to this question: What's the best sort of disk to get today? (ie specific disks on the market in Feb 2010) Generically, what should someone look for when trying to buy something like this that kinda walks the line between enterprise and consumer? Lastly -- is there anything that can be done with current "consumer" disks to make them more suitable for array use? IE can you use a SMART configuration to change the error recovery strategy used by the disk? Thanks!

  • Buying used MacBook, what to look at?

    - by Wojtek
    I'm planning to buy used MacBook, I'm looking for more recent models, but detailed specification is not important. I would like to know what should I especially look at when buying used MacBook? What are common flaws in those models (manufactured 2009/2010)? I don't care about minor damages, like scratches, but would like to know what symptoms of repair/previous damage/possible failures in the future are?

  • Optimum no./size partitions for Windows 7

    - by Pat. Mitchell
    I plan to install a 500GB drive in my notebook (HP dv2613tu/1.5gHz/4MB RAM) and need advice about optimum size and number of partitions to create. Ideally looking for the following: OS (Windows 7 Ultimate) Swap file Applications Data ??? As a long time Mac user I'm not nearly as informed about Windows. I could leave everything as a single partition, but am seeking maximum performance and efficiency from my system (which won't be changing anytime soon). So, would separate partitions help with this aim? And given my usual habit of accumulating stuff, I want to reserve most space for Applications and Data. I've also set myself a project over the next couple of years of digitizing the whole of my 35 y.o. collection of slides and photographs from my travelling days. Thanks. Pat. Mitchell

  • Disable SSD in ASUS 900 running Ubuntu 9.10

    - by ashays
    Recently I managed to completely mess up my ASUS 900, but I have no immediate desire to upgrade since it's only my travel laptop (and I'm waiting for a few months to see if anything interesting comes out). For now, though, I've hit an interesting problem. The 4GB SSD that is soldered onto the motherboard is broken. Since it's soldered on, there's really no hope of replacing it (I believe), so I've been solely running off the 16GB that is inserted into the mini pci-e slot. But since it can't read from the SSD it keeps giving me an error every time it tries to boot and read the ssd. Is there any way to either force Ubuntu to not check the drives on boot or disable the drive altogether, so that I don't have to sit through a 5 minute boot process each time I want to use the computer?

  • Intel Wireless 4965AGN not achieving N throughput when connected to an Airport Express N network

    - by BenA
    I have an Intel Wireless WiFi Link 4965AGN adaptor in my laptop (HP Pavillion dv2000 series) which is connecting to a 5Ghz-only 802.11n network provided by an Apple Airport Express. The network is using WPA2 encryption. My desktop is also connected the Airport, via a Linksys WUSB600N USB adaptor. Both are running with the latest drivers, and the Airport is running the latest firmware. The Airport is also configured to use wide channels. The problem I have is that I never get throughput above 4MB/s when transferring files between the two machines. Even a pessimistic calculation shows a 270Mbps network as being capable of transfer rates at well above 10MB/s. I'm pretty sure I've isolated the issue to being the Intel adaptor, as wiring the desktop to the AP, and using the Linksys adaptor on the laptop immediately yielded speeds limited by the 100MB/s ethernet connection. I know that 802.11n is still a draft standard, and so mixing kit from different manufacturers can easily lead to poor results, but I was just wondering if anybody else out there has had success with this Intel adaptor on an N network? Or even better, connecting it to an Airport Express? Can anybody give me any advice on how to troubleshoot this issue? I should also mention that the Airport Express doesn't allow you to manually specify channels when running in N mode, and that I've been able to rule out interference from other Wireless LANs by scanning. There aren't any other 5GHz networks in my area. All ideas welcome! Update: A while later, I've just updated to the most recent drivers for both the Intel chip in the laptop, and the USB adaptor. Unfortunately this hasn't improved things :(. If anybody has any advice it would be be gratefully received.

  • New Computer Build Questions

    - by MJ
    I'm in the process of gathering parts and specs for a new machine. I wear many hats, so the machine needs to do a lot. I need at least 2 monitor support, if not three. I also play many online MMOs (wow, aion, war hammer, etc), along with some freelance programming projects. I already have a case which is very large, so it will fit anything. I have 2 other SATA HDs. They are more for storage and basic programs. I feel that the best improvement could be done with a solid state HD, true or not? I'm more of a software/programming guy, so ANY input at all on improving this system build would be appreciated. I have a few questions with this list. AMD or Intel? I don't know enough about either to choose what would best fit me. Thanks! **EDIT: Thanks for the input everyone! Here are some answers: I do a lot of programming and gaming, so I do need things for both. The newer video card covers the gaming aspect, as well as allowing me to have many monitors. (hopefully upgrade to dual 30' or more) I don't need any additional HDs at this time. I have a SATA 160g and 120g from my previous computer, and a NAS system with over 2TB of storage on the homenetwork. I just wanted a fast HD for OS/programs/games. With the memory. I have used G.SKILL before in 2 system builds. It's done excellent for me in them. Very stable. **EDIT2: Made some additional changes. Lowered the power supply down to 750, which saves me more $$. Also changed the SSD to 2 WD 650G HDs.

  • What happens when the USB key or SD card I've installed VMware ESXi on fails?

    - by ewwhite
    An SD (SDHC) card installed in an HP ProLiant DL380p Gen8 server running VMware ESXi just failed. I encountered some rather ominous looking messages on the vCenter console and in the HP ProLiant ILO event log... Lost connectivity to the device ... backing the boot filesystem. As a result, host configuration changes will not be saved to persistent storage. Embedded Flash/SD-CARD: Error writing media 0, physical block 848880: Stack Exception. VMware advocates the use of USB and SD (SDHC) boot devices for ESXi. It was one of the main reasons the smaller footprint ESXi was developed (versus the older ESX). I've spent much time highlighting the differences between ESXi's installable and embedded modes to coworkers and clients. However, these failures do seem to happen. In this case, this is my third instance. Luckily, this is a vSphere cluster with SAN storage. What steps should be taken to remediate this failure?

  • Installed ASUS HD4670, now unable to install ANY Debian due to low memory corruption

    - by Alfabravo
    I have a desktop PC which initially had the Intel D946gzis mobo, its chipset as video controller, some RAM and so. There I installed Debian without a problem alongside WindowsXP. I've bought an ASUS HD 4670 video card, installed it on the PC and now the installed Debian does not work, while the Ubuntu live CD refuses to run no matter if I set acpi, apic on or off... it throws me some low memory corruption at position just like shown here. With normal configuration, Debian throws kernel panic (keyboard lights blinking). Anyone have faced this before? Ideas? Thanks!! (meanwhile, debian hides in a virtualbox :'( ) Edited: Tried Ubuntu 9.10 x64 (due to the fact i've a core2duo at 2GHz) and it throws a kernel-panic to me (flashing caps and num LEDs). On screen, can be read different lines with things like: ... [ 1.957161] [] rb_erase+0xd6/0x160 [ 1.957266] [] page_fault+0x25/0x30 Could it be something about this new video card having ddr3?

  • powerpoint make computer shut down on dell optiplex 760

    - by yael
    hello, At my office we upgraded group of computers to windows 7 + office 2010, few of us have problem that when we work on powerpoint - once in a while the computer suddenly shut down (with out any message). Some of us - has no such problems. We checked and fount that the people who experience problems - use Dell Optiplex 760 PC, and everyone that have no problems use other models. We also found out that the processors of the 760's are not the same - some are Intel E7400 and one is Intel E8400, so I suspect that maybe the mother board is the problem Does any one no this problem? Does any one have an idea about it? Any help will be appreciated. Thanks, Yael

  • Customize Firefox Status Bar?

    - by Steven Penny
    For web browsing I use Pale Moon. Pale Moon has a Status Bar, similar to what is now known as the Add-on Bar in Firefox. With Pale Moon when I hover over a link URL is shown in the status bar URL is shown instantly Entire width of status bar is allowed for URL, if necessary With Firefox when I hover over a link URL is shown in a tooltip in lower left corner URL is shown after intentional delay Only half the browser window width is allowed for URL Is there a way to make Firefox behave more like Pale Moon? No Status-4-Evar answers I realize Status-4-Evar might be the best solution here but I wish to see what, if any other options are out there. I will also accept well thought out and referenced answers as to why the Firefox way is "better".

  • What is the minimum power supply wattage needed for a Pentium 2.4GHz system?

    - by scottmarlowe
    It looks like I've got a dead Antec True 330 power supply in an older desktop that has an Intel D845PESV motherboard, a Pentium 2.4GHz processor, 2 dvd/cd writers, 2 hard drives, and other typical devices. I have an even older computer that is not being used that has a 200W power supply. Can a 200W power supply drive what I've listed above? Or, put another way, what is the minimum power supply specs for the above system? (A new 350W power supply will run me $30--so buying a new one is not a problem--but I'm curious about the question nonetheless).

  • Windows 7 detects my 1 TB disk as a disk with only 31 MB space

    - by ZelluX
    I've added another 1 TB Western Digital disk on my computer (there is a disk with 250 GB already), and after booting to Windows 7, it recognise the disk, but in the Disk Management panel, it says the disk has only 31 MB TOTAL space, so is what it shows in the EVEREST information. And when I rebooted the computer and entered BIOS, it said the new disk has 0 MB disk capacity. Is there any way to fix this problem?

  • Home and Small to Medium Enterprise network manufacturer choice, Netgear, Linksys or D-Link ?

    - by Kedare
    (Please don't close this post, it's a serious post so... Be cool, no trolls please, I need an answer ;p) Hello, I am looking for an alternative to Cisco (too expensive for me !) for semi-pro utilization (at home but with advanced feature (I'm studying in IT)) and in small/medium enterprises. I think I will choose between LinkSys (Including Cisco Small Business), Netgear and D-Link, but I've never really used these products, that what I need is a manufacturer that make "almost" all type of networking equipment (Like Cisco but cheaper..), here are my needs : I need almost all my products to be rackable I need a good warranty (Netgear lifetime waranty rulez!) I need an "unified" network environment I made a little comparison of the characteristics that interest me after hours of search on Internet (based on result found on many websites): (Prices are based on the ldlc-pro.com french website) Hotline/Support Quality: Netgear : Not so bad Linksys : Not so bad D-Link : Poor! Most common Warranty: Netgear : Unlimited Lifetime Warranty! Linksys : Limited 3 years warranty D-Link : Limited 5 years warranty (Unlimited in US but I'm on France :(...) VPN protocols compatibles with routers on endpoint mode: Netgear : Only IPSEC :( Linksys : IPSEC, PPTP, L2TP D-Link : IPSEC, PPTP, L2TP Cheaper 8 ports Gb switch : Netgear : 30€ Linksys : 47€ D-Link : 30€ Cheaper 48 ports + 1Gb uplink(s) administrable switch : Netgear : 263€ Linksys : 630€ D-Link : 600€ Cheaper VPN router : Netgear : 100€ Linksys : 80€ D-Link : 60€ Cheaper rackable switch : Netgear : 50€ Linksys : 87€ D-Link : 50€ Cheaper rackable and administrable switch : Netgear : 120€ Linksys : 370€ D-Link : 171€ Netgear and D-Link are in the same range of price, where Linksys is more expensives. I've searched for some other criteria ( the full comparison is here, in french with shop/source links: http://forums.jeuxonline.info/showthread.php?t=1072280 ) and made a final score for each manufacturer : SCORE including IP camera sub-score: Netgear : 6.2/10 Linksys : 7.3/10 D-Link : 7.0/10 SCORE excluding IP camera sub-score: Netgear : 6.9/10 Linksys : 7.0/10 D-Link : 6.7/10 On both case, Linksys wins. So here is my little comparison, but because I've never really used these stuffs, I need your help to make a decision on witch manufacturer choose for both my personnal and corporate use. So here are the questions : What manufacturer do you recommend me (Not cisco (except Small business)) ? Why ? Have you called the call center of the customer support of one of these manufacturer ? How it was ? Did you had problems or bad experiences with these equipments ? Any other advices ? ;) Thank you !

  • Anyone have experience with Silicon Mechanics 4-Node Machines?

    - by Matt Simmons
    I'm taking a look at buying some new servers (small infrastructure, 2 racks, etc), and although I like a lot of the features in blades, I'm looking at the price point for Silicon Mechanics' 4-node machines. http://www.siliconmechanics.com/i27091/xeon-2U-4-Node.php It's a bit like a mini-blade enclosure, but has no shared resources, except for the redundant power supplies. A single point of management would be great, but for the low price point here, I'm possibly willing to give that up, if the server quality is adequate. Basically, have you used these machines? Any problems? Anything you like?
