I will start from the beginning. On the 27th of June 2013 i bought brand new  EVGA GTX 670. It was working perfectly for 14 months. But then, the problems started. My first RMA was near july/august. They sent me back broken card(after installing drivers - artifacts) so there was a second RMA. And now my card AGAIN isn't working properly. Last month i had freeze of my computer but i ignored it(i was thinking that my PC was unstable - overclocked CPU's) I downlocked my CPU's, checked with all possible programs and everything was working perfectly until today. During the game i saw artifacts and computer restarted. Right now its working but during 3dmark tests it's randomly freezing, sometimes it's ok but more ooften it's giving me freezes (the same issue was with my first GPU)
 
My spec:
2 x X5670 @ 4,2Ghz
EVGA SR2
12GB of ram
1 x SSD - system
1 X HDD - data
EVGA GTX 670
ANTEC HCP 1000W

things i've done already:
- reinstalled drivers
- downclocked CPU's to stock values
- checked another card in my rig (it was asus GTX 780ti) - it was working perfectly so I assumed that PSU is not a problem
- last thing but probably most important  - i checked this card in another computer. It passed Firestrike once but i asked my friend to lunch two more Times and after two Times it crashed(screen is fereezing)

I actually love EVGA brand. With their motherboard - EVGA SR2, i dont have any problems, it's  rock solid, OC'ing like hell. But i really have bad luck with GPU. This is already thrid damaged card in a 1,5 year period:/

I will try to record the issue when i will "catch" moment but this is the same issue like the last time:

All settings in bios are set to optimized settings. This is the video i recorded when was my first RMA. I posted it here, beacuse the problem i have now looks exactly the same. All drivers are up to date(also 3dmark). Drivers version is: 347.25(from the 22nd of the january)


GPU is not OCed (i'm using my PC for watching movies, working with doc files and weekend gaming(mainly world of tanks)). GPU temps are up to 65 in stress

sooo, my thrid RMA, i'm always "experienced" customer:/.. so guys should i open it from "my products" site?

So, this is the video I recorded just a few minutes ago. You can see gpu-z screen, with frequency and temps. I launched firestrike and during the second test it freezes, only restart helps.

i highly doubt that;/

this option: "Unless you get another refurbished 670(will most likely die in 6 months time lol)" sounds like me;/
p.s. i wouldn't like to have in 2015 GPU with 128-bit bus^^
 
 
Anyway, Thank you all Guys for help and reading my thread. time for my thrid RMA

so i can't start RMA because i need Support Ticket Number. Gues i need to wait for evga staff here?:)

Thank you very much! I've just sent email to support

Helo again
I never had problems with the qaulity of EVGA tech support. Everything is working great. They answered my email in just 1 hour so i think it's also ok:). Right now i'm in a stage of losing my nerves. I gave my shipment on Tuesday, but it was sent on Thursday(quality of post company in my country - never again). Whats more, someone in this thread post that i will probably receive "another refurbished 670(will most likely die in 6 months time lol)" this also scaring me a lot.

I had some time and already check everything in my computer that could cause problems. I bought new cables for my PSU, i checked many times voltages in my PSU. Everything is working. Right know i'm using my backup GT 210. It is working normaly, without a problem and i have this card since 2010(running without a problems:/) Don't knwo why i have such a bad luck with EVGA GTX670.

Ok finally my card was delivered;) and there is an info: "Part Number Out: 02G-P4-2670-KR" so I hope that this gtx 670 will live longer:)

P.s. I had a little hope that maybe they send me gtx 770 but the most import an is that the card will be good:)
