Fuel Parts/Spares

I normally have various Fuels available; here are some example configurations, grouped by CPU-type. Anything in italics is not available at the moment (sorry!). See after the table for extras, upgrades, notes, etc.

NOTE: The table below denotes systems fitted with a modern ATX PSU, achieved by using a custom AXT adapter kit. This is more reliable than an original SGI PSU and much cheaper, but I can fit an original SGI PSU for extra if preferred. For the modified setup, the PSU model I use is the Thermaltake Toughpower GF1 650W 80+ Gold. Commercial users may prefer to have an original SGI PSU, but bare in mind such original PSUs are now very old.

All configurations come with a free QLOGIC Dual-channel QLA1280 U2W SCSI card, power cable and a free 36GB 10K disk containing a clone backup copy of the system disk. Keyboards and mice are available separately. All systems are now fitted with a minimum of a fast and quiet 36GB 15000rpm system disk (Fujitsu MAS3367NC + adapter); this disk is perfect for Fuel - in terms of access time, it is very good (see my disks performance page), but of course I have higher capacity models if preferred, or I can fit extra disks.

Main Table, cheaper systems listed first. Use price differences and later tables to calculate alternative configurations, or just contact me for a quote. Again, any system shown in italics is not currently available.

(NB: I do not have any Fuels available just now, sorry!)

The main table is ordered in terms of CPU speed. Choose the example closest to your needs in the table, then add on any extras as required (or discounts) - see the list of example optional extras/upgrades after the table, or the Parts/Spares page for the full list. If you're not sure, feel free to email me. Please widen your browser window to see the full table.

Please see the Fuel section of the Parts/Spares page for a full list of available upgrades and extras. Further items such as DVDROM/CDROM/CDRW/DAT units, SCSI cables, etc. can be found on the SCSI Items page.

Please see my Origin3000 Architecture page for background information on the architecture Fuel is based on. Fuel is effectively a single-CPU Origin3000 with one VPro graphics pipe).


See the shipping costs page for details of postage charges to the UK, mainland Europe and beyond. Alternatively, a personal collection is welcome; I live in Edinburgh, Scotland.


DVI monitor cables and adapters are also available - please see the monitors page for details.


Detailed Notes

All systems have a full installation of IRIX 6.5.30m (my own special installation with lots of extras such as Blender, BMRT, Ayam3D, mplayer, OpenOffice, Freeware, Nekoware, Quake2, Quake3, etc.) Adobe Premiere 4.2 is installed, plus many other items, including a good custom desktop layout. A typical installed software list in Software Manager looks like this, though I can of course customise in any way required, or even just put on a default installation with no extras if preferred.

All systems come with the Octane2 VPro demos CD, my custom SGI Nekoware split (8 CDs) and my SGI Gifts CDs. See the IRIX CDs page for details of these CDs. Alternatively, I can include a full 6.5.30 CD set for +60 (email for details).

V12 graphics is the best graphics option available. V12 has 128MB combined VRAM/TRAM (up to 108MB for textures) and supports more resolutions than V10. It is though exactly the same speed as V10, the only difference is VRAM capacity and thus support for additional higher resolutions, deeper colour modes, etc.



Background Information (Comparisons with Octane2)

For full details, see my Fuel page, but here is a summary...

CPUs found in Fuels range from R14K/500 (2MB L2) to R16K/900MHz (8MB L2), with speeds of 600, 700 and 800 inbetween. 800MHz and 900MHz systems are much harder to find and thus more expensive, but even a 700MHz CPU causes a significant price jump.

The maximum RAM is 4GB (4 DIMM slots). The system architecture compared to Octane2 has 4X faster SCSI (U160 instead of UW), 2X faster PCI (which comes built-in as standard!), 2X faster RAM, 2X faster system bandwidth, lower RAM latency, less noise, but audio is not included as standard. An M-Audio Revolution 7.1 PCI card is the best audio board to look for; the other board one can use is the Audigy2 ZS, but it's definitely not as good as the Revolution 7.1 (the Audigy2 can be kinda noisy). Fuel does have some degree of support for Firewire and USB (see www.nekochan.net for details), but it varies greatly. Hobbyist strive to improve this all the time, but it's not something with which I keep up to date.

Fuel has two internal 5.25" bays included, DVDROM typically fitted, but not always; some people have been able to use DVDR/DVDRW drives ok, but this does require a recent version of IRIX and up-to-date Nekoware apps (I can install 6.5.30 instead if required). The system has two internal 3.5" bays for disks, though one could always employ the 5.25" bays for extra disks aswell if required.

For raw speed, a 500MHz Fuel can be 40% to 50% faster than a 400MHz Octane2 with a good disk, ie. a better speed increase than is implied merely by the 25% higher clock speed. Application startup times are much improved. Fuel can take good advantage of a nice 15K drive since it has U160 SCSI. The graphics can only be V10 or V12 (just one pipe), but Fuel can get more out of them compared to the same options in Octane, though one would only notice this if working with more dynamic datasets, or if some aspect of displaying the model was CPU/memory bound, eg. repeated conversion from a prioprietory database to Performer.

Fuel already has 4 PCI slots included. PCI with Octane requires either the expensive PCI cage or an XTalk adapter, so Fuel has an advantage here. Also, Octane's PCI is only 33MHz, whereas two of Fuel's slot run at 66MHz, allowing Fuel to take good advantage of high-performance SAS, SATA and other storage technologies (eg. just a single SSD can do over 270MB/sec in a Fuel).

If you can make good use of dual CPUs, then Octane2 may be a better choice though, eg. for use with Blender, Maya, SoftImage, or other applications that can use dual-CPUs for rendering (any professional video, animation or effects package will be able to use dual-CPUs), though there comes a point where Tezro may be more cost effective. Thus, if single-threaded speed is more important (ie. running applications such as OpenOffice, Seamonkey or Firefox), then a 600MHz Fuel with a 15K disk is a very nice system (I recommend the Fujitsu MAX series), especially if you don't care about audio since most Fuels do not come fitted with an audio board by default, whereas Octane has audio built-in as standard. By contrast, dual-CPU Octanes are nice when using applications that can use multiple CPUs, but good dual-CPU Octanes (ie. dual-R12K/400 or better) are a lot more expensive than a single-CPU Octane.
