Title: [SCRYPT] 5970 cards....am I reading this right? Post by: Ritual on January 13, 2014, 05:44:56 PM So Radeon 5970s can put out 750 khashes?
I'm being offered 6 of these for £60 each, with a couple more quid for shipping. I have to take the 6 if I buy. It's my cousin, so I know he's not a scam :) Am I misreading this? Or is this card an absolute monster for the price? EDIT: For the US readers, that's about $80 I think? (each) Rit. Title: Re: [SCRYPT] 5970 cards....am I reading this right? Post by: Jama on January 13, 2014, 06:21:30 PM They can, it is basically 2 x 5870's in one package.
I used to run lots of 5870's could push about 400 a card. The only issue is they get very toasty, the hash per watt is quite a lot worse than a new card. I would eat his arm off for that. If you don't want them all I would happilly buy them Title: Re: [SCRYPT] 5970 cards....am I reading this right? Post by: Ritual on January 13, 2014, 06:30:42 PM I think I'm just gonna do like you said....I'll try to leave his arm intact above the elbow :D

(a) Play safe and go 2 seperate rigs with 3 cards each....OR (b) Attempt to be a tech ninja and run all 6 off one mobo.... :D Rit/ Title: Re: [SCRYPT] 5970 cards....am I reading this right? Post by: crazyates on January 13, 2014, 08:57:37 PM So, the next question is whether: (a) Play safe and go 2 seperate rigs with 3 cards each....OR (b) Attempt to be a tech ninja and run all 6 off one mobo.... B isn't even an option, so you'll have to go with A. The 5970 is a dual-gpu card, so each card shows up as two GPUs to the OS. You can't have 12 GPUs, as even in a 64-bit OS the drivers cap out at 8. Twin rigs with 3 each are fine, as long as your OS is 64-bit, as that's only 6 GPUs per rig. TL;DR 5970 = Dual GPU card 32-bit OS = limited to 4 GPUs (or 2 dual-GPU cards) 64-bit OS = limited to 8 GPUs (or 4 dual-GPU cards) Title: Re: [SCRYPT] 5970 cards....am I reading this right?

And....I shoulda known that :P stoked over new cards! Rit/. Title: Re: [SCRYPT] 5970 cards....am I reading this right? Post by: merred on January 13, 2014, 10:15:06 PM I have one. Pain in the ass for configuring.
Buy for 60 sell for 150 Title: Re: [SCRYPT] 5970 cards....am I reading this right? Post by: crazyates on January 14, 2014, 03:41:04 AM Make sure to get some beefy PSUs! Those cards are north of 350W each, IIRC. Undervolt as much as you can. You will just about have to, if not for power than also for temps.
Just buy 3 of these, and run 2 GPUs off each PSU. A little overkill, but not too expensive considering you're looking at just under 5Mh/s. |
