Title: [WTS] Sapphire 7970 Vapor-X OC 11197-03-40G - voltage unlocked - EUROPE BASED Post by: Boxman90 on September 03, 2013, 08:31:46 AM I'm selling 11 Sapphire 7970 Vapor-X OC videocards.
Mining is no longer profitable with the ridiculous (~0.28$/kwh) where I live. I'm based in Europe, but will ship worldwide. Shipping costs are for the customer. The price is 2.9 BTC per card.

Any particular reason these are worth so much? Over other OEM's i guess?

But they are quality product they stay much cooler then other simple designs often even beat 3 fanned model cards cooled ones Possible very high overclocks also because of the prefect cooling. But i allready know for a fact that really kills your cards in time much quicker then if kept at certain speeds Mine runs perfects at 1050 core however i ran them for many months at 1190 however i lost one now because the could not cope the heat from mining constant for almost 2 years. I mine full at scrypt at around 68 C and that is not even with using fan setting at 55% it fully runs on auto fan speed. Ofcourse on hot days when its 34 to 36 C it breaks the 75c mark but hell these cards can handle it with ease As you ofcourse know if you put more into a case they heat each other which will effect the performance Title: Re: [WTS] Sapphire 7970 Vapor-X OC 11197-03-40G - voltage unlocked - EUROPE BASED Post by: mrkubanftw on September 03, 2013, 03:53:26 PM Yeah okay that makes sense. My sapphire 7950 dual-x would run at a hot 78 depending on the day when it was oc'ed and at 100% fan load. Annoying is what that was lol. So i would say its worth it! I'm shopping around right now but ill let you know if im interested within the next day or two.

That technics has proven to be working well, i was sceptical when i bought them But when i bought several other brands second hand i found the vapor-x ones allways be just a tad bit better, cooler and more stable. Ofcourse when i put 4 in my cramped i7-3770 system with the case closed it became sometimes steaming hot. Especially when i was gaming from morning till early morning ;) Ofcourse maxing out every bit i could squeeze out of all my games, and trying out all demo's from games i was curious about. Now by this is am just saying they are good cards ofcourse i do not know how much they where abused by this user xD Title: Re: [WTS] Sapphire 7970 Vapor-X OC 11197-03-40G - voltage unlocked - EUROPE BASED Post by: Boxman90 on September 03, 2013, 10:20:08 PM In terms of hashrate, they all were capable of reaching 750kh/s with overclock, no overvoltage.
They ran 24/7 for a few months at ~720kh/s. They never ran at higher than stock voltage. Temperatures were kept <70C, but duging high summer (40C outside), some did reach 79 C. I can guarantee the 720kh/s hashrate for being 24/7 stable when cooled properly (2 120mm fans per 4 cards). |
