Hi!
are you running yourself a business or are you employed?
if you're employed or running a business yourself you may not have to pay the swiss VAT or rather get it back at the end of the year - provided you fill out the tax declaration/return the right way

BLJ you have completely confused me about the memory
The Tyan MOBO supports this-
Memory
• 128-bit dual channel (interleaved) memory bus
• Total eight DDR DIMM sockets (four per CPU)
• Supports up to 16GB of Registered DDR
• Supports ECC with CHIPKILL Technology
• Supports DDR 400 / 333 / 266 memory
That is not really right.
The Mainboard has 8 dimm Slots and so supports 8 DIMMs.
BUT... AMD K8 architecture has the memory controller inside the cpu. And the memory controller determines what is supported and what isn't!
Each Opteron 2xx has 1 Memorycontroller and 2 'core processing units' (or however they're called..).
The current K8 CPUs unfortunately only supports two doublesided Dimms @ DDR400/PC3200 command rate 2 and four doublesided Dimms @ DDR333/PC2700 command rate 1.
You could buy 4x1GB today and upgrade with additional 4x1GB later. But then they could only run at DDR333/PC2700 and Command rate 2.
Id don't know if maya is such an application, but there are applications make good use of memory bandwith, so cutting down from DDR400 to DDR333 wouldn't be that nice
So you might think you'd want to go for 2x2GB now. But that again would mean each core only would have 1 dimm what again means that they're running singlechannel. Thus only have of the possible bandwith...
so you might spend some extra money on 4x2GB now (costs quiet much more - around 1200CHF) - what would be the optimal Solution.
OR look for SingleSided 1GB Dimms. There are a few Singlesided 1GB Dimms, per Example MDT. To say it straight MDT sucks. And at least there are no 1GB SingleSided Dimms currently available at the swiss normal retail (end user) market...
thats quiet complicated, isn't it?
-------
ok the next part is only repetition:
ZitatSo the fastest memory that it can support is DDR 400 right?
If I buy 4x1GB DDR now and then in the future when Maya comes with a 64bit version I can buy another 4x1GB DDR400 RAM. To have total of 8GB.
it is possible but then they won't run @ DDR400 but rather @ DDR333!
ZitatWas your point that by doing this I won't be able to get to the maximum possible for the Tyan MOBO which is 16GB?
no.
ZitatWas your point that I should get 2x2GB DDR400 sticks now
You could. But that would leave you with half of the bandwith of 4 Modules.
Zitatso that in the future I can buy 6x2GB DDR400 modules to take the total to the maximum possible for theh MOBO which is 16GB?????
no... 16GB sound cool ... and a little insane =D (and very expensive!)
ZitatSorry I am really confused I think you meant something else
i can understand that. My english's crap so it's just normal that you understood 'crap crap crap woompa crap crap'
