Remember... With the arrival of the SLI much pointed finger the need for having a food surpuissante in its PC. It should be said that to feed GeForce 6800 WP or Ultra of the time a food 480 Watts constituted a minimum. The arrival of GeForce 7 frankly did not change gives it and a muscular food is always necessary for top-of-the-range systems SLI. But with QuadSLI it is not any more question of food 500 Watts, but of food 1000 Watts! Thus our machine of test it was equipped with a Tagan food of 950 Watts... Hello the note of electricity! Noisy, we already said it, QuadSLI heats however almost reasonably since we reach, at worst the moment in our tests, a temperature of 65° for the GPU. That remains almost correct when it is known that they are certified for a maximum of Centigrade 130°.

Impressive, the charts GeForce 7900 GX2 however are subjected to the constraints of our modern PC and the laws of physics: doors, they tend to twist whereas the slots PCI-Express train 16x which support them are put at hard test. Thus on our machine of test, the system of maintenance of the second slot PCI-Express train 16x was quite simply broken. Who more is the condensers of these charts have the annoying tendency to unsolder himself, which occurred on one of our charts of test. NVIDIA seems conscious of these defects, this is why the next generation of QuadSLI charts should post more reasonable dimensions. That should avoid besides the problems of poor contact which we could observe of time to other with either the appearance of artifacts to the screen, or of the twinkling red zones sweeping the screen. It should however be recognized, with the discharge of NVIDIA, that the machine which we could test had somewhat bourlingué with with its credit a aller/retour in CeBIT and another in India. Lastly, the pilots are not inevitably mature, our planting system in a rather random way in particular with Splinter Cell Chaos Theory in 2048x1536 with activated antialiasing or Far Cry under the same conditions... Another observation, by activating antialiasing under Doom 3 or Quake 4 various phantom images appear: is needed of débarasser to be used good profile SLI, free to modify it to obtain the desired adjustment.

To test the performances of QuadSLI we could have a complete configuration, in the event the machine that LDLC will market in the Hexagon soon. Here the detail of the configuration.

* Mother board Asus A8n32-sli Deluxe (BIOS 1103),
* Processor AMD Athlon 64 Fx-60,
* 2x1 GB Corsair TwinX 3200C2 Pro,
* Disks hard Western DIGITAL Raptor 74 GB in RAID

The system functioned under Windows XP Professionnel Service Pack 2, here in English version with all the updates available. To test QuadSLI we had recourse to the pilots ForceWare 87.24 in Beta version. We will compare here the performances of QuadSLI with the performances of a SLI of GeForce 7900 GTX but also with the performances of only one GeForce 7900 GTX and only one chart GeForce 7900 GX2. If we used pilots 87.24 for the 7900 GX2 we had recourse to pilots 84.25 for GeForce 7900 more traditional. We will not fail to make appear Radeon X1900 XTX of ATI, unfortunately in version simple chart, the chart Master CrossFire having arrived us too late. Radeon X1900 XTX here tested on the same platform and accompanied by the CATALYST 6.4. Side resolution we adjusted our protocol of test: exit 1024x768 and 1280x1024 and hello 1600x1200, 2048x1536 and 2560x1600!
