TriFire / QuadFire HD 7750

[elfuego123]

Hello everyone!

The AMD Radeon HD 7750 supports software crossfire. Thanks to the lack of CF bridge connector, actually bridging the cards is not an issue. So, is it actually possible to form a 3-way crossfire (TriFire) or 4-way crossfire (QuadFire) with these cards?

This site actually lists a TriFire 7750 combination:

But other than that, the information on the net is scarce. Did anyone actually try out such a setup?

Thanks!

You can but what's the point your still severely restricted by the 1 GB limit of Vram and you'd need a expensive motherboard and larger PSU... its more expensive than say getting a 7870 LE

The point is - the HD 7750 is at the moment, the only feasible passively cooled video card out there. The passively cooled Powercolor HD 7850 jumps up to 100+ degrees C under full load, so that card is out of the question for a 0 dB PC.

Correct me if I am wrong, but I think that 7750 crossfire on the other hand, or even TriFire / QuadFire would theoretically be able to deliver somewhat decent graphical performance at 0 dB within normal operating temperatures.
