What router to get?

I just got a new powerbook G4 with airport card and am ready to try wireless but new to this concept. I understand I need some sort of a base to connect to my internet service. Is the airport express base station all I need? Or do I need a router too? Is there a better base station? what do people like? So, I think I just need one piece of equipment right? A base station/router? Are they the same thing? Help me - I'm a newbie with this stuff.
Thanks!

Marty,
Thanks for the answers, you can never have too much detail, it really helps.
I'll get down to money straight away, just rough prices, (rip-off britain) UK prices (in US dollars) so you may get better prices where you are.
First choice is a new Ethernet and Wireless DSL modem / router, probably about $120 for a good one. You can then ditch your existing modem / router (or sell it). It'll have a good antenna, giving good reception for as far as you want. It'll be Mac and PC compatible, configured by a web browser, with built-in javascript setup wizard, rather than using the Apple Airport software. PC's and Macs can be cabled to it or wireless (or both at the same time if you really want). You'll get all the Firewall security of your existing modem / router, probably with a few new extras too. It won't give you true wireless printing, but as you know you're limited by the printers that it supports. Anyway, if you attach the printer to the PC (W2K or XP) you should be able to share it with your new PB.
Next choice, is the same as above, but with a built-in USB Print Server, probably around $200. Same caveats with printer models. This would give you true wireless printing, if you really wanted it.
Next, just a wireless router, around $50, to plug into your existing modem / router, giving your PB wireless access. This would have it's own antenna, giving good wireless reception. Configurable with a web browser, like above.
Next, Airport Express, which is basically just a wireless router, with USB Print Server and Airtunes support. It doesn't have an external antenna, which is the only thing I have against it. This hasn't stopped me buying one and then another, but the wireless range might not be up to what you want.
If you can decide what type you want, we could make recommendations, probably Netgear or Linksys. Belkin tend to be naff, but they seem to be getting better (but so are the others).
Can you give us an idea of just how far you expect the wireless range to be ? And through how many walls ? and are they internal (plasterboard or brick ?) ? or external ( brick ? stone ? other ?)
I have 3ft thick stone walls in my house in Edinburgh, nothing gets through. (Aberdeen on Scotland's north east coast has all pre-1930's housing made of 3ft granite, it was calculated to be strong enough to withstand an air-burst nuclear hit).

  • I am assuming the Time Capsule needs a router, my router is old, what is the best router to get?

    I have the Time Capsule and a very old router.  I am assuming that I have to have a router, what should I get for a new router?  Can the Time Capsule be its own router?

    The Time Capsule is a wireless router, but it does not have a modem on board, so you will need a modem to be able to connect to the Internet.
    The "best" modem to use is probably one that your Internet Service Provider supplies, since you know that it will be supported in the event of difficulties. Often, an ISP will give you a modem free of charge with a commitment for a year or more of Internet service.

  • Upgrading from TCS 2.0 to TCS v. 2.5 - Know What You're Getting!!!

    I'm not the type to normally write in forums but I just went through 2 days of customer service and technical support hell and thought I would share the experience with the sole motivation being to spare fellow TCS users the aggravation and make you aware of a possible disconnect between sales and technical support - know what you`re getting!!
    Yesterday I purchased the upgrade from TCS 2.0 to TCS 2.5 from the Adobe online store as an electronic download. After receiving a confirmation email I logged into my Adobe account and noted that the download page contained 2 serial numbers, one for Photoshop CS5, one for Captivate 5 and then a zip folder for UPDATES only to Framemaker and Robohelp and also 2 language packs for text-to-speech for Captivate 5. Obviously I was missing links to Framemaker, Robohelp and Acrobat.
    The goal of my purchase was to procure an additional licence in order to install TCS v 2.5 on 2 additional computers so, I had a sick feeling that I may have misunderstood what was offered in the upgrade; I then had the following conversation with Adobe`s Chat Live Now (excerpted from transcript):
    Me: Hi. I just  purchased the upgrade from TCS 2.0 to TCS 2.5. My expectation was that  this contained all programs within the suite yet on my downloads the  only programs that are listed are Photoshop CS5 and Captivate 5. Does  this upgrade package not include the ability to install Framemaker,  Robohelp and Acrobat. I purchased on the assumption that the upgrade  would constitute an additional licence for these products as well. Was I  wrong?
    Perkins: ...TCS includes all programs, you need to select those programs while installing.
    Me: Okay, I'm just  downloading it now so I will confirm that it does, in fact, include all  of the programs. So just to clarify, my original understanding was  correct and the upgrade provides me with 2 additional licences for TCS?
    Perkins: Yes. You can install 1 copy of the software on 2 computers with same Operating System.
    Okay - fair enough, I then re-visited the Adobe Technical Communication Suite 2.5 web page under Upgrade--Reasons to Upgrade where it states:
    ``Work with full new versions of Adobe professional tools for technical  communicators and help authors, including Adobe® FrameMaker® 9, Adobe  RoboHelp® 8, Adobe® Captivate® 5, Adobe Acrobat® 9 Pro Extended, and  Adobe Photoshop® CS5 software``.
    Now to me, FULL means full versions. I subsequently entered customer service hell and spent an hour and a half on the phone being transferred through 5 different people, none of whom were familiar with the contents of the Technical Communication Suite. It took forever jsut to get them to understand that I weas upgrading from TCS version 2.0 and NOT trying to upgrade from Photoshop CS4 and Captivate 4 directly. Eventually my question as to whether I was entitled to an additional licence for Framemaker, Robohelp and Acrobat Pro Extended was elevated to Tier 2 and I was told I would be contacted by Adobe. Today I received a voicemail and email stating that I should install Framemaker, Robohelp and Acrobat Pro Extended from my original TCS v 2.0 installer. I subsequently did so (successfully) and then installed Captivate 5 without issue.
    The next challenge arose with Photshop CS5 - the serial number, according to the installer, was invalid. Back to customer support who referred me to technical support - turns out the download link on my Adobe account download page was for a Chinese language-only version of Photoshop Extended which doesn`t even come with TCS 2.5! So, another 90 minutes on the phone throughout which I keep seeking clarification, does TCS 2.5 grant me an additional licence for Framemaker 9, Robohelp 8 and Acrobat 9 Pro Extended...
    Technical Service states they can send me a physical disc with installers for Photoshop CS 5 and Captivate 5 and then CONFIRMED that I am NOT entitled to any additional licences for Framemaker, Robohelp or Acrobat, I am ONLY entitled to the 2 installs under the original TCS version 2 licence. This of course runs completely contrary to the literature on the website and my conversation with Live Chat Now. In disgust, I have submitted a refund request.
    Just for kicks I decided to again try to clarify with Live Chat Now what products that I, as a customer, receive a licence for by purchasing the upgrade to TCS v 2.5 and have pasted the transcript of that chat as follows;
    Me: Can you please  confirm for me whether upgrading from the Adobe Technical Communication  Suite version 2.0 to version 2.5 entitles me to 1 additional licence for ALL of the applications that constitute the Technical Communication  Suite (i.e. Robohelp, Acrobat, Framemaker, Captivate, Photoshop and  Presenter) OR does it merely entitle me to 1 licence to install  Photoshop CS5 and Captivate 5 in conjunction with my pre-existing TCS  2.0 installation?
    Morph: Give me a minute, I’m reading it.
    Me: sure
    Morph: When you place the order for upgrade, you will get new products.
    Me: I understand that I will get Photoshop CS5 and Captivate 5 BUT do I also get Framemaker, Acrobat and Robohelp?
    Morph: Adpbe eLearning  Suite  2 includes: Adobe Captivate 5, Flash Professional CS5,  Dreamweaver CS5, Photoshop CS5 Extended, Acrobat 9 Pro, Adobe Presenter 7  (Available only on Windows platform), Soundbooth CS5.
    Morph: No.
    Morph: Only Acrobat is Included.
    Me: I am not talking about the e-Learning Suite, I am referring to the Technical Communication Suite
    Morph: Oh okay, got you, first tell me, using which product you will be upgrading this from?
    Me: TCS 2.0
    Morph: Okay.
    Morph: Yes, if you do this  upgrade you will get Adobe FrameMaker 9, RoboHelp 8, Adobe Captivate 5,  Photoshop CS5, Acrobat 9 Pro Extended, and Adobe Presenter 7
    Me: so this will  entitle me to 1 additional licence for all of these applications, over  and above the licence I already own for the TCS version 2?
    Morph: Correct, however,  you may also be installing the software (Upgrade version) directly  without uninstalling the previous version of the software.
    Me: So just to  clarify, if I purchase the upgrade and decide that I want to install on a  completely different machine than the two computers that already have  TCS version 2.0 installed (as entitled by my licence) then I will be  able to, in effect, install the TCS 2.5 onto two completely different  computers (as per the Adobe licence) so that, at the end of the day, I  can actually have FOUR computers with TCS installed by virtue of the 2  licences that I should have - one from TCS version 2.0 and 1 licence  from TCS version 2.5É
    Morph: Purchasing the  “upgrade” version product is nothing but a “full” version, but if you do  not have the serial key for older version you can’t Install the  upgrade, but for full version you do no need previous version serial  number.
    Morph: Correct.
    Morph: You can simply purchase your upgrade and verify that you have the qualifying older product during the installation process.
    Morph: If it's installed on  your computer, the Adobe installer will either find it or prompt you to  help it find the software for verification.
    Morph: If it's not installed, you will be prompted to enter the qualifying serial number for the older version.
    Me: Is the download file one individual installer or an installer for each application
    Morph: It is one Indiviidual Installer.
    Morph: When you download it will automatically Install every program in the Suite one-by-one.
    Me: Okay, the reason I  have been asking is that yesterday I made this purchase yet my download  page had links only to Photoshop (a Chinese language only version of  Photoshop Extended which does not come with the Suite) and Captivate.  There was no link whatsoever for the other applications. I went through  customer service and technical support and no one, and I mean no one,  could answer the questions I`ve asked you. According to customer support  and the serialization team, the upgrade to v. 2.5 DOES NOT include  Framemaker, Robohelp and Acrobat. As a consumer I have absolutely no  idea what is right and what is wrong. How am I supposed to make an  informed purchase...
    Morph: did you check on the link and confirmed that it does not Include the upgrade to version 2.5?
    Me: Sorry - not clear what you mean, my receipt from the Adobe store was for TCS v 2.5
    Morph: Like I said  upgrade for the Technical communicate suite Includes Adobe FrameMaker 9,  RoboHelp 8, Adobe Captivate 5, Photoshop CS5, Acrobat 9 Pro Extended,  and Adobe Presenter 7, and you should be getting all as a single  download link, seems like you are not able to make it with the link to  Install Individual products altogether, so you need to contact our  Customer Service at 800-833-6687. for the
    Morph: precise Info.
    Me: I went through  that route yesterday and today and they told me that the upgrade DOES  NOT include the other applications. As well, I noticed that the download  file size for the upgrade is 1 half the size of the full version -  obviously something is missing
    Me: The information you are telling me is the precise opposite of what they told me. How do I, as a consumer, get the proper answer
    Morph: upgrade do Includes the product I have mentioned above.
    Me: I know you`re  trying to assist but I`m flummoxed - my case was escalated to Tier 2 and  they told me it doesn`t include the other applications
    Morph: up to some  extent i can help being a sales team member, ant only customer people  generate the links and have access to customer account to check what  really went wrong.
    Me: Is it possible to  have a senior sales rep contact me - this matter of a `simple` upgrade  has consumed a ridiculous amount of time. As far as my issue - Adobe  tells me nothing was wrong and that the upgrade is only a licence for  Photoshop and Captivate
    Morph: Okay,Just a minute.
    Morph: You can contact our Sales Team on 1-800-585-0774.
    So, at the end of the day, sales tells me that upgrading to v 2.5 grants me an additional licence for ALL applications in the suite whereas Adobe`s own technical support has told me this is not true. Again I ask, how does a consumer make an informed choice...
    I`ve been buying Adobe software for both Mac and PC since Creative Suite 2 came out and this has absolutely been the most frustrating experience I have ever had. I get great use out of the Techncial Communication Suite and thought it would be nice to have an additional licence but at the end of the day I have decided it certainly was not worth the hassle - particularly when Adobe itself can`t figure out what I am entitled to!!
    I am a fan of Adobe`s software but honestly, is business that good that you can treat your customers this way????

    Hi. I suspect that may indeed be the case. If so, that's fine but nowhere is it clearly articulated what a user gains by purchasing the upgrade (and I am specifically referring to an upgrade from TCS version 2 to v 2.5) and certainly sales (as evidenced by my chat transcripts where I believe I asked quite specific questions) are advising customers that you will, in fact, gain an additional licence to ALL components of the TCS by upgrading.
    If it had been clearly articulated on the Adobe TCS 2.5 website that an upgrade from TCS version 2 only entitles users to install Photoshop CS5 and Captivate 5 in conjunction with the existing installation of the other components of TCS 2 - or - better yet, stated clearly that the upgrade from version 2 to 2.5 does not entitle the end-user to an additional licence for Acrobat Pro Extended, Framemaker, Robohelp and Presenter 7 then that would allow me, as a consumer, to make an informed decision whether to make the purchase. Since that is not the case, and Adobe's sales representatives are clearly advising customers otherwise, I felt compelled to post this so others don't waste their time as I did trying to sort it out. At one point I was advised that I should use my existing TCS version 2 installer to install Acrobat etc but received contradictory answers as to whether I was entitled to an additional licence for these products. At no time during my first hour and forty-five minute conversation, my second ninety minute conversation nor my third, and last, twenty minute conversation was anyone able to clearly articulate what you have stated - and - that still leaves the fact that the text on Adobe's website is misleading.
    BTW - why I received a download link from Adobe for a Chinese-language-only version of Photoshop CS5 Extended is still a mystery
    At the end of the day, I think the TCS (while not perfect) is a very useful tool and I will, in all probability, upgrade to the full version of TCS 3 which will, no doubt, constitute a full licence for all components of the suite. I am not attributing malicious intent to the Adobe employees, but I am saying that they themselves seem confused about what is included in the upgrade and provided contradictory statements. If Adobe employees can't provide a straight, cut-to-the-chase answer about what seems a straightforward question then that certainly creates unnecessary confusion for the customer.

  • See what routes your eigrp advertises to you?

    Hello guys,
    Today I realized that I do not know a command that could tell me what routes my eigrp neighbor advertises to me.
    I am on the hub ASR routers which terminates many DMVPN tunnels and I would need an effective way to see what routes one of the remote routers advertises to me, similar to advertised-routes in BGP
    How can I find it?
    Thanks a lot!!

    The only thing that I can think of is to filter your topology table with:
    sh ip eigrp topol all-link | i ^P|<ip address of neighbor>
    You'll get back all routes in the topology table, but the address of the neighbor that you filter will show and no others.
    You'll get something like below:
    R1(config-router)#do sh ip eigrp top all | i ^P|192.168.12.2
    P 2.2.2.0/24, 1 successors, FD is 409600, serno 8
            via 192.168.12.2 (409600/128256), FastEthernet0/0
    P 3.3.3.0/24, 1 successors, FD is 128256, serno 10
    P 16.16.16.0/24, 1 successors, FD is 2560025856, serno 9
            via 192.168.12.2 (2560025856/2560000256), FastEthernet0/0
    P 192.168.12.0/24, 1 successors, FD is 281600, serno 1
    R1(config-router)#
    If that doesn't work, the only other thing that I could think of is a tcl script to filter it out for you.

  • If you traded in your mac mini for a windows pc, what would you get?

    I have a late 2009 Mac Mini and am just chafing to upgrade. It's slow as molasses.  But at the same time, I'm not willing to pay full price for 2012 model, and Apple is way behind in releasing an update. In fact I'm hearing speculation that Apple may be just discontinuing the Mac Mini.
    I don't know... But I'm getting tired of waiting. And getting a different model of Mac doens't work for me, because I want to use my own screens. (I'm running two large screens in "portrait" mode.)
    Also, I have a Windows 7 PC at work, and I've come to realize that I don't mind Windows 7 and don't see it as intrinsically better than the Apple OS. In fact Windows & has generally been mariginally more stable, and a lot faster then the OS on my Mac. In fact I got both systems around the same time and the Windows 7 system did better with less RAM and is "aging" better.
    HOWEVER, what I really love about the Mac Mini is how QUIET it is. I have it in my bedroom, next to my bed, and it's noise is barely noticeable. So I guess I should look into seeing if there area any desktop PC's that are as quiet.
    Have you considered switching back to a PC, and if you did what would you get?

    I moved away from Apple in 2007 and have never looked back !
    I use the ASRock Vision X 420D  http://www.asrock.com/nettop/Intel/VisionX%20Series%20(Haswell)/ 
    Its the same size as the current Mini but a bit taller - BUT it is FULLY user upgradeable and about the same price once you make a mini upto the same spec.
    I run Windows 8.1 on it and love it - yes there are lots of people bleating on about the 'metro' style of Win 8 but if you configure it (which has been a feature from launch, not a 3rd party hack) you never have to see the metro interface and you have a standard desktop.
    As to woodmeister50 comment of : Also, with Win8, many third party add on companies have dropped support etc. is that not the same for Mavericks ?!

  • Advice on what Mac to get? Thinking about either a Mac Pro or iMac...

    I am a graphic designer. I have a Power Mac G5 (older model before Intel) at home. I love it! Want to upgrade but it works for now. Anyways at work (I am the only designer) everyone uses a PC (including me) but I am getting my Christmas gift. They will be ordering me a new Mac! Problem is I'd like some advice as to what I should get. I was originally thinking of the Mac Pro G5 (tower) but then started wondering if an iMac would be a better option. Most of what I do is Adobe Creative Suite programs (but currently I have so many problems with it taking forever to open and save some of the files I am working with especially in Illustrator I am working on a map that is about 21,000 KB). We will be upgrading to CS4. I want to get something that will last for several years and speed up my time. I become impatient when having to wait on my computer to save or edit something. Also, is there any advice on connecting to a windows network. I am not an IT type and everyone here is familiar to Windows. Thanks!

    Mac Pro is the only answer. And like already said, hold on for end January and MacWorld Expo to see what might come along. Intel promises great things in the next few months, the floating point arithmetic spec for the new Intel Nehalem processors show nearly a 100% increase in speed from the current top-end Penryn processors:
    http://www.techradar.com/news/computing-components/processors/world-exclusive-in tel-s-dual-socket-nehalem-ep-platform-benchmarked-487131
    And you may start to see 4-core processors even in the iMacs. This is the Intel way forward, more cores, 6 cores, 8 cores, up to 80 cores, but little increase in clock speed over 3GHz.
    Can't promise Mac Pro will get the new processors in January, could be Snow Leopard time, a very late xmas present then.

    How will I assign all Customers to different Tranp. Connec . Point.

    I am unable to find the deliveries Craeted.

    How will I assign all Customers to different Tranp. Connec . Point.
    In Route : When We define the transporation connection points do we have always have to specify the
    Reference Customers?
    Yes you need to give refernce Customer or reference shipping point then only system will pick route properly because Route gets determine based Customer and shipping point only(Transportation Zone).
    Normally Transportation connection points will be used when the route have different stages.
    Fro Example route from Coimbatore to Channai in this route we have 4 stages 1.Thiruppur 2.Salem 3.Erode 4.Villupuram.
    Here you can define 5 transportation connection points 1.Coimbatore 2.Thiruppur 3.Salem 4.Erode 5.Villupuram. Based on these Transportation connection points Route stages will be defined.
    In Coimbatore transportation connection point you need to assign Coimbatore Shipping point
    In Thiruppur transportation connection point you need to assign Thrippur Customer.
    In Salem transportation connection point you need to assign Salem Customer.
    In Erode transportation connection point you need to assign Erode Customer.
    In Villupuram transportation connection point you need to assign Villupuram Customer. Based on this system will now all the stages comes under single route.
    In the Shipment Documents Creation: VT01n
    I am unable to find the deliveries Craeted.
    While creating shipment document you need to select the deliveries Through the delivery selction screen by clicking on Deliveries push button or press F6 deliveries will not come directly in to the shipment document.
    Before going to select deliveries that deliveries should relavent for the transportation and should not complete the PGI.
    I hope this will help you,

  • What causes BUFFER GETS and PHYSICAL READS in INSERT operation to be high?

    Hi All,
    Am performing a huge number of INSERTs to a newly installed Oracle XE 10.2.0.1.0 on Windows. There is no SELECT statement running, but just INSERTs one after the other of 550,000 in count. When I monitor the SESSION I/O from Home > Administration > Database Monitor > Sessions, I see the following stats:
    BUFFER GETS = 1,550,560
    CONSISTENT GETS = 512,036
    PHYSICAL READS = 3,834
    BLOCK CHANGES = 1,034,232
    The presence of 2 stats confuses. Though the operation is just INSERT in database for this session, why should there be BUFFER GETS of this magnitude and why should there by PHYSICAL READS. Aren't these parameters for read operations? The BLOCK CHANGES value is clear as there are huge writes and the writes change these many blocks. Can any kind soul explain me what causes there parameters to show high value?
    The total columns in the display table are as follows (from the link mentioned above)
    1. Status
    2. SID
    3. Database Users
    4. Command
    5. Time
    6. Block Gets
    7. Consistent Gets
    8. Physical Reads
    9. Block Changes
    10. Consistent Changes
    What does CONSISTENT GETS and CONSISTENT CHANGES mean in a typical INSERT operation? And does someone know which all tables are involved in getting these values?
    Thank,
    ...

    The table just have 2 columns, both of which are varchar2 (500). No constraints, no indexes, neither foreign key references are in place. The total size of RAM in system is 1GB, and yes, there are other GUI's going on like Firefox browser, notepad and command terminals.
    But, what does these other applications have to do with Oracle BUFFER GETS, PHYSICAL READS etc.? Awaiting your reply.Total RAM is 1GB. If you let XE decide how much RAM is to be allocated to buffers, on startup that needs to be shared with any/all other applications. Let's say that leaves us with, say 400M for the SGA + PGA.
    PGA is used for internal stuff, such as sorting, which is also used in determing the layout of secondary facets such as indexes and uniqueness. Total PGA usage varies in size based on the number of connections and required operations.
    And then there's the SGA. That needs to cover the space requirement for the data dictionary, any/all stored procedures and SQL statements being run, user security and so on. As well as the buffer blocks which represent the tablespace of the database. Since it is rare that the entire tablespace will fit into memory, stuff needs to be swapped in and out.
    So - put too much space pressure on the poor operating system before starting the database, and the SGA may be squeezed. Put that space pressure on the system and you may enbd up with swapping or paging.
    This is one of the reasons Oracle professionals will argue for dedicated machines to handle Oracle software.

    Help required. I don't want to use NetworkManager.

    The following might be useful:
    https://access.redhat.com/solutions/783533
    "When transitioning from NetworkManager to using the network initscript, the default gateway parameter in the interface's ifcfg file will be depicted as 'GATEWAY0'. In order for the ifcfg file to be compatible with the network initscript, this parameter must be renamed to 'GATEWAY'. This limitation will be addressed in an upcoming release of RHEL7."
    NetworkManager is now the default mechanism for RHEL 7. Personally I don't quite understand this, because as far as I can gather it is a program for systems to automatically detect and connect to known networks. I think such functionality can be useful when switching between wireless and wired networks, but for a server platform, I wonder.

  • Corsair: 3 DDRPro types, What should I get?

    My 2x256K RAM is about 20MB-200MB short when running certain games. So Im going to get 2x512s. Corsair pros seem to be a good choice as they have very low latency.  From what I hear, low latency is how AMD users make up for not having the bandwith Intel chips have. (I know I have a 333 FSB, next year Im going to a 3200+ CPU):
    However, this is confusing me. Corsair 3200PRO-series sticks seem to have three types. XL,LL, and C2.  I orignally wanted the XL bc it had the lowest latency(2-2-2-5) vs. LL (2-3-2-6), C2(2.5-3-3-6). Why all the choices?
    Here what I can tell: The XL only comes in twins. The LL and C2 come seperately. The C2 can appearantly work on "intel platforms". Then it get real confusing, because if you look at the individual spec pages, only the LL mentions it can be used on "nForce 2 Ultra". Cant they all given that they all list at DDR400?
    http://www.corsairmicro.com/
    What should I get?  I read that DDR only makes a 3-5% difference. So I would forgo the twins, BUT they only sell the XL (2-2-2-5) latency in a twin pack. So there may be more of a gain here in the XL series.
    Will I notice the difference in latency of seperately buying 2 LL(2-3-2-6) sticks over the XL(2-2-2-5) twins, or is this just a paper gain that no one really notices?
    If Im doing overkill and can accomplish a gig DDR 400 at a lesser cost, please let me know. The "bling" lights on the Pro sticks is not that much of a purchase factor. I just want speed.
    Sorry for the long first post. I couldnt find anything upon several searches.
    FWIW: Thanks to Wonkaboy, Raven, the guy with the robot in his sig, and everyone else who contributes. I now have  the fastest and most stable computer I have ever used or owned. I had no problems bc of the compilations in the stickys. Very good work on those.

    Wonkaboy conviced me that with the costs of prosticks (and a AMD3200+) I would be halfway to another system:
    I went to get the same model # as min current twins (2700LL 2-2-2-5), but corsair doent make 512K 2700LL . So I had to settle for 512K 2700C2(2-3-3-6).
    If I read the above link right Im only looking at a 1-2% difference anyway
    The auto detect was configured 3-3-3-7   . So I went in and changed it to 2-3-3-6.  I cant get it near 2-2-2-5(but I didnt toy with voltage or any other FSB parameters).  I may try 2-3-2-6 but Im giving up after that. I tried other-lower settings but it didnt work. Again, Im to scared to start toying with the voltage, I dont know enough and dont want to fry the system.
    Any comments are appreciated as far as setting the ram speed. Id like to get 2-2-2-5, but it looks like I may settle for 2-3-3-6.
    My computer runs much better now that it has enough ram to not bother with page file swaping.
    Thanks Wonkaboy and Raven!

  • Just bought a 30 pin digital AV adapter. What other cords get attached to  it besides the one from computer to adapter and the one to keep the iPad charged. I have another hole to fill on the adapter.

    Just bought a 30 pin digital tv adapter. What other cords get attached to it besides the power cord to the iPad and the link between the tv and the adapter.? I have a hole for another cord.

    The HDMI goes to the TV.
    The USB goes to the charger.

  • SSD for OS/Programs/Pagefile - What size to get?

    Hey all,
    I am in the process of upgrading my hard drive setup on my system and am planning to purchase a SSD soon.
    Once purchased, I plan to go with a 3 disk setup. I see this calls for the OS, programs and pagefile to go onto the SSD. I'm trying to figure out if a 128GB SSD would be large enough for this, or if I should go with a 256GB.
    Currently my computer is showing 82GB used on my C: drive. I'm pretty sure I only have OS/Programs on this drive (and I've never messed around with Windows pagefiles so I'm assuming that's on there too). I've been pretty careful to not let random files float around on my C: drive, and after some quick checking around I didn't see anything out of the ordinary. (I did however find an "appdata" folder that was ~20GBs). Is this pretty much par for the course when you have the programs on this drive? Or should this be on another drive?
    With a 128GB drive, it's my understanding that after formatting, you really only have ~119GB. And is there some sort of guideline out there for keeping a SSD somewhat open for optimal performance? If it's something like "25% should be kept free" then I suddenly only have ~89GB to work with. Being at 82GB already makes me wonder if I'm cutting it too close. Especially if I decide to install more programs down the line (C4D, 3DsMax, ZBrush, etc).
    Thoughts on what you all would do? Would it be ok to maybe move the pagefile to another HD (even in a 3 disk setup)? I'm not even sure how large my current pagefile is at the moment, so I don't know what that would get me. Is there even an issue filling up a SSD past 75%? If not, then I'm probably worrying over nothing.
    Thanks!

    128GB is a great size for a boot drive (OS, programs). if you have other drives putting the pagefile on rotating drive is probably optimal, but you could put in on the boot SSD as well. There are those who say it is a total no-no to put swap on a SSD but there are millions of laptop users with single-drive SSD systems and they seem to work just fine!
    Regarding how full can a SSD get, you can fill them more than a traditional drive since they do not get fragmented.
    Regards,
    Jim

    Given that this is the iPad forum, most of us have probably picked the iPad. If you asked in the iPod Touch forum, most people there would probably have picked the iPod Touch.
