Want!
http://www.intel.com/products/motherboard/D5400XS/index.htm

oh yeah and enough money for the 2x quad core cpu's and quad sli to go along with it.

Ha, you sell-out! Whatever happened to Ubuntu on a 386? Laughing

More seriously, I wonder how many systems they will sell with quad video (outside of games deelopment studios)

need to find a 386 with a floating point unit and you have a chance,
the default kernels they ship with now all require it, otherwise its slackware version 0 for you.

The science and CAD communities might have use of them, that whole using the video card to do massively parallel processing thing.

Ah, the Skull Trail mobo Razz

Shat loads more of information here:

http://www.tomshardware.com/2008/02/06/intel_skulltrail_part_1/
http://www.tomshardware.com/2008/02/07/intel_skulltrail_part_2/
http://www.tomshardware.com/2008/02/08/intel_skulltrail_part_3/

Conclusion:


quote:
Conclusions: Technologically Immature And Lacking Software Support

We were disappointed by the Skulltrail platform. Although we have tested and reviewed numerous Intel products, we have never had such a half-baked system such as this in our labs. If this sounds harsh, bear in mind that all we have to base this conclusion on is the Skulltrail system itself in its current state, which Intel provided as an official review platform. We do not know whether Intel plans to revise and improve the platform before the final versions ship to retail.

The Skulltrail system is unable to keep up with current desktop systems with a single quad-core processor by a long shot. We are not considering workstation applications here, since such applications are simply not the focus of the platform at this time. The main performance problems can be attributed to how Intel chose to use a chipset from the workstation segment, from the use of FB-DIMM memory and from the lack of widely multi-threaded software. Most applications can take advantage of four processors at most, meaning that the second quad-core CPU is practically never in use.

Also, the quality of the board is - simply put - very bad. Due to a lack of crucial options, the BIOS is not suited for overclocking, the Southbridge fan is far too loud, the PWM fan-speed regulation for the CPU cooler does not work and the board takes far too long to boot. Several times, the board even crashed when restarting.

It is incomprehensible why Intel would send a platform plagued with so many problems out to the press in such a rush. Currently, Intel is not under any kind of pressure from the competition - it has already proved that it makes the fastest CPUs in the market. So why create such a dubious platform? Considering the performance that can actually be harnessed by today's software, the platform's energy consumption is far too high. While Skulltrail theoretically offers the option of using SLI or CrossFire configurations, any single-socket system offers higher gaming performance at a much lower price.

The performance weaknesses of the Skulltrail motherboard's workstation chipset are its downfall. With games, the system falls behind the two single-CPU desktop systems by up to 45%.

In the benchmark suite, the two Core 2 Extreme QX9775 CPUs are even slower than a single QX9770. Although the Skulltrail dual-CPU system shows very strong performance gains in 3D rendering and video encoding tasks, its overall performance score is still hobbled by its gaming weakness. In the end, a single QX9650 Compare Prices on Core 2 Extreme QX9650 is only 3.9% slower overall than the two QX9775 Skulltrail chips together.

I benchmarked one for work. It's good, but not amazing.

Mostly it is let down by the slower FBDIMM DDR2 RAM. Also while running dual quad core CPU's is great, not much can take advantage of it properly.

Overclocking was also a dissapointment. The server board BIOS is just not as robust an overclocker, you can get much faster speeds out of the socket 775 version of the CPU. (QX9775 vs QX9770)

Also with the videocard side of things, you can run 4 cards but not all in SLI or Crossfire. You can run two cards in SLI or Crossfire, and in theory run both SLI and Crossfire at one. Also in theory if NVIDIA released the drivers you could do quad SLI.

For a pure games machine it still gets beaten by a single quad core PC with 3 videocards in TRI SLI.

Despite all that, I was sad when Intel wanted it back.

What would happen if i run a pc power supply from a inverter??
I was reading and some sites said a psu needs a steady regulated sine wave to run effectively and not fry pc parts while another site said that it didn't matter and it would run off the inverter soo which site is right Question

It would run but it would stress the components pretty heavily on the input side, the rest of the PC should be ok with it though. (not the monitor though)
Your better off getting a 12V > ATX power supply, they can be had for a modest sum and work pretty well.

so something like this would run it and not stress the components really hard??

yeah but that needs 24v dc input and really expensive
you should be able to get one for 30-70 or so off ebay.
what are you trying to do?

My computer is unhappy. It lost the use of it's Ethernet port several weeks ago. It now requires two or three power ups before it will turn on. It is about four or five years old. The Ethernet port is built onto the Asus P4P800.

I use Norton 360 and Adaware.

Any ideas?

Perhaps find (download, burn, copy from someone, get sent one free) a Linux Boot CD (Ubuntu or Mandriva if you would like help from Experienced Linux Gurus here).

Boot the system from the CD (It wont change your hard drive), and test to see if it boots ok and your network runs ok (or not).

If it does, The problem is in the windows software installation and you can look deeper into that area.

If it doesnt, you may have a faulty network chip and will have to disable the onboard card and fit a PCI network card instead (they're usually under $15)

Please clarify what you mean by "power ups before it will turn on" - does the power (light, fans etc) not come on at all until 2 or 3 button pushes, or does the power come on but windows fails to boot ? Does it get partway then stop ? Any errors reported ? At what point does it stop ?

Thanks Brett.

The computer tower sounds like it is turning on normally. The monitor turns on briefly (ie the LED at the bottom of the monitor glows green for a few seconds and then turns amber as if the tower is off). The mouse and the key board lights don't turn on. The floppy drive LED flashes. The computer is then shut down by holding the power button for five seconds. After the computer actually starts, it says that it was not shut down properly.

The device manager shows a question mark in front of the ethernet port.

I will download a Linux Boot CD and burn and try it tomorrow.
