Dual Motherboard

[tizzy88]

Does any one know is it possible to build your own computer with 2 motherboards which run at the max ram??

that's not even a question ...
there is no way of syncing two mobos that I've ever heard of (which probably doesn't mean much)

processors stack on a single mobo - not the other way round

Even if it is technically possible (and I am not sure it is) what benefit do you think you would get running two motherboards?

To use 2 screens ? (you can do that anyway with one motherboard)

To use more than 4Gb of memory ? (you can do that with one motherboard)

To use more than one CPU? (a single motherboard can run a dual core cpu or a quad core cpu).

To use more than one hard disk? (you can of course do that anyway)?

To run more than 1 operating system (you can do that with 1 motherboard)

To run 2 graphics cards? You can do that on one motherboard as well.

So if none of the above, what do you hope to gain?

The nearest thing I can think of that you want to do is something called a Blade Server.

Here you just slot in and new computer into a reack of computers, so in effect you are adding a new motherboard.

Well i was just thinking would it be posible to do. you can max 1 motherboard to 8 gigs as far as i know and about 3.75 ghz.
this would be a good computer but x2 and you would have one aworsome computer a total running pwoer of about 16 gigs and about 7.50ghz.

max memory is a mobo thing - the processor can address far more - but the mobo mfrs have set 8 at the mo
and really lots of ram doesn't make a huge difference
if the progs you are running don't need it - they won't use it

graphics (still and moving) take massive amounts of ram

blades increase capacity not power - operating systems such as unix will "thread" tasks accross a number of processors (data server will use up to 64 processors)

in effect they are seperate machines co-ordinated by the o/s so without the O/s it's not going to work.

processing power is different to speed
a fast processor thinks quickly
threading breaks down a task and shares it accross a number of processors. (similar to raid)

alternatively - with thin client - word is loaded onto a central machine - and people access it using their own thread

either way in effect it's the bandwidth that's big - not the machine that's fast

when I started
in medium scale data processing there used to be a 3 second rule - if any operation took more than three seconds it wasn't allowed into the system - overall the machine could deal with 1000s of requests - but each request took time to process.

This isn't entirely true.

While one motherboard is a set thing (under von Neumann architectures anyway), you can get far more RAM, and multi-core processors.

Check out the Mac Pro. It can use 32GB RAM, and 8 cores. It uses pretty standard components.

it is all dependant upon the motherboard and its chipset. most max out at 16GB, others can go to 32GB and 64GB. While some may not even have a limit.

also, processors are not limited to just speed alone. but they use threads and cores. the new i7 CPU's have 4 cores but 8 threads (most likely what the macpro is).

basically the argument is that you can not link up 2 seperate motherboards to work as 1 motherboard.
