I was considering those, since this (https://bitcointalk.org/index.php?topic=433426.0) guy gets 820kh/s from them.

Yes its MSI gaming card, I have tried his settings, I don;t know why, but I am getting 600Kh/s using his settings... Considering the fact he has 67C on one card and 80C on second I am assuming its just a fake..

But anyway, I'll consider it with my purchase.

And it gets hot faster when I set all fans to 70% Title: Re: Split from: [Group Buy] SAPPHIRE TOXIC R9 280X 3GB GDDR5 [SOLD OUT] Post by: dentro on January 30, 2014, 03:53:28 PM how many power does all cards draw?

My new Watt-o meter shows approx 1400W :) Wow, that's a lot for 4 cards.... Your KH / W ratio is so low :| Title: Re: Split from: [Group Buy] SAPPHIRE TOXIC R9 280X 3GB GDDR5 [SOLD OUT] Post by: jameschase on January 30, 2014, 07:36:31 PM how many power does all cards draw? My new Watt-o meter shows approx 1400W :) Wow, that's a lot for 4 cards.... Your KH / W ratio is so low :| There are some advantages of working for a big corporations. My fiancee for example works as an accountant for the power distributor we are getting power from. They do give 90% discount for everyone who works for them I think. Or up to 100% depending on Your position there. I do have a nice -90% tho, so power usage is not a big concern for me ;) I played abit with the script settings for ya, this is the result for less than 1250W for all: http://s10.postimg.org/jloheckqh/1250.png GPU 0 - MSI Gaming Twin Froz GPU 1-3 Sapphire Toxic EDIT: Settings same as in previous post, but memory down to 1500 in all cases, gpu-engine: 1050,1086,1086,1086 all fans at 55 Title: Re: Split from: [Group Buy] SAPPHIRE TOXIC R9 280X 3GB GDDR5 [SOLD OUT] Post by: jameschase on February 07, 2014, 09:10:05 PM Guys, please be carefull with tweaking Your card. I think I pushed it too much, or GPU was bad since the begining(always had some higher temps than others). I found my card dead recently :(
Replacing it soon, maybe I will try some cheaper one, like Powercolor and see how much I can squeeze out of her... |
