Chi ha provato questa scheda madre? Potrebbe essere necessario piazzato sopra un ventilatore domestico ad alta potenza... bo Title: Re: Cooler Master HAF XB per 2x7990 Post by: Fede on December 10, 2013, 04:02:25 PM il case è disponibile su Amazon, sta sotto i 90€.
Per la scheda madre non l'ho mai provata, ma sostanzialmente una vale l'altra: basta abbiano gli slot abbastanza distanziati.

Quote I am running 4XMSI7990 (http://www.amazon.com/gp/product/B00A3KGW4K/ref=as_li_qf_sp_asin_tl?ie=UTF8&camp=1789&creative=9325&creativeASIN=B00A3KGW4K&linkCode=as2&tag=blog0200-20) without problem on Gigabyte GA-Z68AP-D3 ATX Intel Z68 Express DDR3 (http://www.amazon.com/gp/product/B005M2AQQY/ref=as_li_qf_sp_asin_tl?ie=UTF8&camp=1789&creative=9325&creativeASIN=B005M2AQQY&linkCode=as2&tag=blog0200-20). I use two OCZ 1250W Gold power supply, which is too high for 4X 7990. If I run 3X 7990, one 1250W PSU is OK as I undervolt, the power consumption is less than 400W each card. My setting: 1.0V VDD, core/mem 950/1000MHz. When it runs at 1.2V, the power consumption is much higher than 400W, maybe 550W each card. The temperature varies due to the quality of thermal paste application on the GPU.

visto che 400w sono il 60% in più rispetto ai 250 della 280x e i 1200kh/s sono il 60% in più rispetto ai 750 della 280x se riesci a mandarle sui 1300, guadagneresti solo il 6% in più sull hash...

Title: Re: Cooler Master HAF XB per 2x7990 Post by: neoxxx on December 16, 2013, 03:54:41 PM ...metti anche un bel impianto a liquido per tutte le gpu, altrimenti dureranno poco li dentro ;)
