Quad-SLI de 9800 GX2 = 8 GPU

It's far from the first supercomputer created with the help of some gaming hardware, but this rig built by a group of researchers from the University of Antwerp is certainly impressive enough in its own right, with it employing four of NVIDIA's high-end GeForce 9800 GX2 graphics cards (which combined pack eight GPUs) to help develop new computational methods for tomography. Dubbed the FASTRA, the system also packs an AMD Phenom 9850 processor, 8GB of RAM, and 750GB hard drive, all of which is powered by a 1,500W power supply (and tastefully lit up with some blue LEDs). That apparently lets 'em do calculations that previously took an hour in just a few seconds, not to mention finally get a decent frame rate in Crysis. Be sure to check out the video for a thorough (and more entertaining than it should be) overview of the system.​

porque amd ??

Motherboard: MSI K9A2 Platinum

We searched for a motherboard that has four physical PCI-Expressx16 slots and has double spacing between each of them. There are several boards in the market with four graphics card slots, but we could find only two that have the required double slot spacing: the MSI Quad Royal, which is now outdated and hardly available anymore, and the MSI K9A2 Platinum. We originally intended to choose a platform suitable for an Intel processor, either Skulltrail or NVIDIA 790i, but none of the available motherboards satisfied the slot requirements. Ultimately, we decided to go for an AMD chipset, as CPU performance is not a major concern in our case anyway. Note that the K9A2 motherboard has a very modest price tag and lacks several features found on more expensive motherboards.

Esqueçam a utilidade disto em jogos. Só se for para aquecimento no inverno e facturas de energia titanicas.

o rendimento de 4 gráficas é igual a 1 uma em jogos.

o objectivo disso é uma maquina com poder de processamento puro. :D

são quase 5 teraflops :wow:

E utilizaram aquela lian-li, com 10 baias, isso porque uma caixa ATX normal só tem 7 e estas gráficas ocupam 8
 
Eh pá, eu aprendi que se deve deixar sempre um espaço entre a board e outra placa, isto assim não aquece mais, ou os orificios traseiros tratam disso?
Não quererás dizer antes entre cada placa??
Como vês não é possível isso acontecer além de que eles certamente que tem umas quantas fans a mandarem ar fresco para dentro da caixa

9800GT = 8800GT + Hybrid SLI

It is funny that the GeForce acceleration result is lower than single 9800GT, we thought this is caused by the not good enough forceware.

realmente achava estranho a grafica só fazer 7500 3dmarks
