Costs

Unfortunately, the cost of building an XBOX PC runs a little more than the cost of the XBOX. We need to factor in the cost of the mod chip, probably a hard drive, keyboard and mouse. Mod chips run anywhere from $40 to $80; the one we use in this review costs about $75. A USB keyboard and mouse usually run another $15. If you are going to be doing any clustering, you do not really need to invest in a keyboard/mouse at all. For most uses, the 8GB hard drive is sufficient enough, although upgrading to a 20GB drive might be in order for a larger Linux distribution.

Used and refurbished XBOXes range from $120 to $160. Used XBOXes are usually the way to go, since we will be soon voiding the warranty anyway to install the mod chip. When shopping for an XBOX to mod, older is sometimes better. Although the SmartXX mod chip works on all versions of the XBOX available, the newest version 1.6 XBOXes require a few extra wires to be soldered, even on the solderless install kit.

For our distributed computing ideas, we have an exciting analysis in store. We managed to round up 8 XBOXes with mod chips for this review. That only equates to 5.8GHz of distributed CPU power, 80GB of hard drive space, and just 512MB of memory. However, if our distributed computing project is successful, scaling to a much higher CPU clock might be very feasible. Finding an equivalent $1600 PC would be nearly impossible, but that assumes our distributed XBOX network actually behaves like a $1600 PC instead of 8 $150 PCs. It may be the case that network and disk latencies are too high for us to practically compute anything. There are also some issues on power consumption and noise. The XBOX is relatively quiet for a PC, unless you have a whole lot of them. Our lab recorded approximately 42dBA when our eight node XBOX cluster was on.

If you plan on just running your XBOX as a stand-alone PC, then costs like power become no issue. The XBOX consumes 100W at full load. For a 16-cluster node to operate for one hour, we need 1.6 kilowatt hours of power. If you pay 10 cents per kwh, that's about $1400 for one year of operation.

    I was just wondering if you will do a test with mental ray on the cluster (I think you mentioned something about Mental Ray in the article). It would be really interesting to see the results of that since me and a couple of friends got modded X-Boxes and I have a 3dsMax6 license (Mental Ray is included). Reply

    You might want to look at the "mini-cluster" project (http://www.mini-itx.com/projects/cluster/) when planning/designing/building your EPIA cluster. It's a 12-node (originally 6) cluster developed by Glen Gardner, and appears to be the same size or a little smaller than a stack of an equal number of XBOXes. Of course, the frame is custom built and the hardware is exposed to the world. Reply

    I can say that I love having a modded xbox, because the capabilities are so much greater. As discussed earlier, a software mod can be a great way to do it (although it usually requires a game unless you want to take your HDD out, which is NOT a fun method unless you love swapping IDE cables.)

    It's also good to note that you should be careful when modding these or even make a backup of the hdd on your system, because things can go wrong, and if you like to fiddle with things, then your chances will be a lot higher. I know at one point I was stuck in error 16 and had to pull the HDD out and unlock it using the IDE swap method.

    Are there plans for an article on modding something such as the PS2? I just recently tried a no-solder modchip in the PS2, and it doesn't seem to be going along too well. Maybe it's time for a flip-top.

    "We crimped our own cabling as you can see in the image below."

    I'm still looking for the image, I know its there somewhere!

    If anyone wants their xbox motherboards upgraded to 128 megabytes of memory, I can do it

    I'm UK based and use BRAND NEW samsung memory chips

    I can upgrade your existing motherboards, sell you ready upgraded boards, or even just the chips!

    if one of the anandtech team wants their xboxes upgraded i'll happily do it at cost, please contact me to discuss

    First, XBox live banning....

    Basically this is how it used to work. When your on live it does a hash of your bios. A mod replaces your bios. If you bios is not the retail ms bios the serial (eeprom) is blacklisted. NOW since halo2 has been released it appears that MS has changed a while bunch of shit on us. Preliminary information indicates that MS is banning by hard drive serial+model numbers, xbox serial, and flagging the gamertag as 'potential pirate'. Thus to unban the xbox both a new hdd and eeprom are needed. Then you must cancel and create a new xbox live account. There are more details about how it all works but bottom line is we dont know how it works now. They can throw new stuff at us anytime now. Rumors are flying that hdd capacities are being scanned as well. For all intents and perposes xbox + modded xbox's do not mix.

    Yes there is a PS1 emu for xbox. That said xbox DVD drives do not read cd-r (or retail ps1 games) Therefor all games must be transfered to the xbox hdd in bin/cue or iso format

    When comparing mods remember, the mod contains no modded bios stuff. They are useless in them selves. You will need to aquire a modded bios for your xbox (online, free). What this means is that every mod can contain the same bios's. Therefor they all contain the same base features (mostly booting unsigned code). Hardware features and support is where you want to base your decision on. If you want cheap + no manufacterer support there are 10$ solutions around for you(enabled/disables with power button). If you want support with a mod with a few extra hardware features (2 bios's, external switch) that'll cost around 30-40. Fancy Shamcy lcd support, 8 bios banks, blah blah blah fancy external thing thoes are up to 75ish. But in the end they all allow you to run the same software on the xbox.

    After seeing Halo 2, it makes me wonder if they really need Pixel Shader 2.0. Its pretty cool that I can play old games on the XBOx through emulators though but i wanna see when the next XBOX kicks off before spending $200. Reply

    #12, probably not. The Xbox's GPU is a GeForce 4 class GPU - the lack of Pixel Shader 2.0 features can really be limiting. Reply

    is there any way to use the gpu for the pov-ray rendering? Reply

    Little quote that sums up the SmartXX XBL saga:

    Q: just bought a Smart XX mod and I still don't know if i'll be able to play xbox live so please somebody tell me if i'll be able to play it.
    A: There is no easy way to answer this question. First of all, it all depends on circumstance. Have you upgraded your hard drive? Has your Xbox ever been banned before? And, for newbs, are you thinking about playing on live while using a bios from the chip.

    If you answered yes to any of these questions you've won a lifetime ban from Microsoft!


    Sleep time :) And i don't even use XBL :D
