I bought four of these cards in January, one by one they dropped like flies, got one left. Ironically the three that have died had Hynix memory and the one remaining card has Elpida, and hashes much lower than the other 3 cards.
What temps did you run them at ? Bought 3 of those 2 months ago, one died the first week, possibly because i ran them at a 80°C target, but the others survived probably because i keep them below or at 70°C now. I can reach 620Kh/s with fans at 70%. The remaining card is running at 72 which is roughly what the other 3 were running at.

I do have to reboot it regularly though.

I also have an older model (11196-16-20G) and that one's been working perfectly since early last year!
I've also had one card of the 11196-16-20G model for about 8 months running 24/7. The place where I keep the mining rig (due to absolute lack of space) isn't well ventilated and the GPU stays at ~82 celsius most of the time, with the VRM's at ~90 celsius. I know that's high but there's nothing I can do about it right now. Anyways, the card has been running perfectly all that time without a single freeze ever. I was really disappointed with the fans Sapphire used on the card though - very low quality chinese plastic and horribly noisy even at moderate speeds. Wouldn't buy another Sapphire card again.

When my gpus dead, drove out a bit of oil through the VRM heatsinks and the oil wetted a part of the card pcb. have you happened something similar to this? Do you see a lot of oiled the VRM heatsinks of your cards? ![](https://ip.bitcointalk.org/?u=http%3A%2F%2Fi62.tinypic.com%2F2v3mxzq.jpg&t=665&c=lz7lk_LfxOUJ-g)

I have 2 new fried cards here (took about 3 weeks to fry each of them, they broke down about 3 weeks apart). Again, no overclocking, no firmware modifications.
These cards are absolute crap. I don't understand how any shop still sells them.
I'm going to RMA them one last time and dump them on the second hand market as soon as I get them back. This'll be the 7th time I send a card back within 4 months.
SKU (both cards): 11196-19 And both cards are: A135100030xxx

just now starting the RMA process for my sapphire 7950. A fan started buzzing on it, wobbling, led to load tems at 100C, and only 250kh/sec (scrypt)...

Just had a reply from RMA today for a card I sent in a couple of weeks back. Apparently they are low on stock. This could mean Sapphire is working on a revision? Or it could mean nothing at all and the shop is just short on cards.
Any other guys having to wait long for their latest RMA's? They said they expect new cards around the 2nd of April...

Just found this thread, it is shocking to read about all these issues. I have 8 of these cards and after reading all the posts here I immediately checked my S/Ns. So I have 3x 1350 and 3x 1351 in my collection and I am a bit worried now. I haven't experienced any problems with them yet, they are running 24/7 for about 1.5 months now. I run them at stock clocks (925/1250) and undervolt to 1006-1056. Temps are 60-73 Celsius.
So do we have any facts about the source of issues? Or only assumptions? Has Sapphire made a statement anywhere? The manufacturer should know best of all of us. Are all cards from the 1350/1351 batch affected or only a portion within these serial numbers? Questions which needs answering, rather sooner than later. Summer is comming soon and we don't want more fried gpus.
I can confirm that the fans are crap. Had already RMAd two cards in the past as they had issues. Hope the others will do better.
Has anyone already experience with the Sapphire R9 280 (non-x) cards? 11230-00-20G do they have better fans? Or are they bad as well?

I bought 10 of them from 3 different vendors around January.
I got 4 from the same vendor with serial numbers A135000034xxx : 2 of them didn't last more than a month. (The 2 remaining gpus from this batch are still mining).
6 are from 2 other vendors and have different SN A135200017xxx, A140400054xxx and different bios, I have a mix of Hynix and Elpida RAM and till now I had no problem with them.

I've been running 3 of them in a rig 24/7 for about 3 months now. No problems whatsoever.

I have 10 of these cards and have been running for 4 months now. Only one so far ![Lips sealed](https://bitcointalk.org/Smileys/default/lipsrsealed.gif) has had a fan die on it. They run around 75C and haven't shown any signs of dying. I do need to dust them off though. ![Wink](https://bitcointalk.org/Smileys/default/wink.gif)

These cards with these SN, no working in my case more than 3 months 24/7. RMA with Sapphire is very slow, more than 3 weeks and two of my dead gpus haven't been repaired yet (they said me that the problem isn't identified yet)

Hello just want to make a small comment. I have a couple of farms with sapphire 7950s, but mines are 16-20G not 19, I have close to 100 cards, and never ever burned one. (I do however, have to repair fans every week).
-First maintain the card's VRM below 80 Degrees it is a must!, keep them BUG FREE (I mean real bugs, you know biological ones, I often have some ant or small spider get in there and fried, and that hangs the card, as soon as I clean the bug's remains, the card works again).
-Second never EVER OC over 950 Mhz.
I can see a LOT of people here overclocking at 1050Mhz, that's NUTS, man these cards are designed to 860Mhz, push them to 950 is already too much, but 1050 is absolutely insane!.
I operate my cards at 950 MHz except in the summer where I lower them to standard default clock of 860Mhz, yes, I make less money, yes I babysit my cards, but the cards are still there... all of them, after more than 7 months working 24/7
think about it, besides the difference in profitablity doesn't worth burning a single card.

The problem with Sapphire is only with the model 11196-19-20G and only with specific Serial numbers. Vapor editions have more quality components except with the fans that i think are holy crap in most Sapphire cards.
