i was planning to use some 5850s. Title: Re: BUILDING A 4 VIDEO CARD MINING RIG Post by: ND on June 15, 2011, 04:12:32 AM 5830= best bang for your buck (if you can get 2 you are golden)
5850-70 = awesome stuff 6950-70 = top notch 6990 (1 or more) the best you can buy right now Title: Re: BUILDING A 4 VIDEO CARD MINING RIG Post by: mu50stang on June 15, 2011, 04:17:22 AM What motherboard and powersupply do you suggest.
Title: Re: BUILDING A 4 VIDEO CARD MINING RIG Post by: ND on June 15, 2011, 04:27:41 AM Get a cheap mobo if you are planing to use single cards. Get a good mobo capable of 8x/8x for crossfire.
For PSUs it depens on the cards: (quality = OCZ,CORSAIR, ANTEC) 5830 single: a quality 550W psu 5830 crossfire: a quality 600-700W psu 6950-70 singles: a quality 600-700W psu 6850-70 crossfire: a quality 800-850W psu 6990 single: a quality 800-850W psu 6990 crossfire: 1000W+ quality psu Title: Re: BUILDING A 4 VIDEO CARD MINING RIG Post by: mu50stang on June 15, 2011, 04:36:51 AM if i have a motherboard with 1x16 slot how do i get more x16 video cards on it.

For 2 or more card you need a mobo that support crossfire. Those mobos have 2,3,4 pcie slots.

Title: Re: BUILDING A 4 VIDEO CARD MINING RIG Post by: ND on June 15, 2011, 05:06:14 AM i dont know? for single card just pick one xD (asrock mobos are the cheapest)
for crossfire look for a mobo capable of 8x/8x crossfire (2 cards). for more cards (3,4) mobos can be expensive so i dont know just get a good one. (asus,gigabyte,msi) Crossfire Mobos (2 cards): ASRock P55 Deluxe Asrock P55 Extreme ASUS Maximus III Formula Asus Maximus III Gene ASUS P7P55D Deluxe Asus P7P55D Premium ASUS P7P55D PRO Asus P7P55D EVO MSI P55-GD65 MSI P55-GD80 |
