Second X1900XT dies within weeks... WTF is this?

[T2k]

AFter I got my replacement board, now my second X1900XT has died too, when I was simply browsing my files... I don't get it, seriously. WTF is this? Am I being haunted? When I built my new rig first my brand new mobo died, when I got it back fixed, my brand new VGA died. I got it replaced, it was working fine for weeks, Prey was running great and cold in 1920 (<a target=_blank class=ftalternatingbar...d=f4747549bb8a11d2389d25a7a68f3f6a</a>">EK block</a>without any OC) for hours - then, few days later, when I was simply browsing my files on my home NAS suddenly the machine got frozen, restarted and there's no picture anymore... I can see it not only boots up fine but starts loading, presumably the OS...
That's one thing that I'll replace the VGA again but what if the new one dies again? :disgust:
Should I try to get some other type of card? I'd stay with ATI and AFAIK all mfr's more or less follow the same reference design... dunno what to do...

PS: when is X1950XT excpected to hit the shelves?

What are the rest of your system specs? That's almost like having 2 cpus die on you -- in other words, highly unlikely.

 

[T2k]

Yep, exactly. Specs are on my page: http://anandtech.com/mysystemrig.aspx?rigid=32666

Which brand?

power supply :?

"restarted and there's no picture anymore... I can see it not only boots up fine but starts loading, presumably the OS..."

What do you mean by this :? How can see you your comp boot up fine when your VGA is dead :? can you see the start up process on your monitor or windows logo :?

your specs dont say what psu u're using. for such a high end rig, u should be using top of the line. from having 3 components die unexpectedly i'd definetly suspect the psu.

Could be a grounding issue killing your components, or a PSU that isn't up to the task or is faulty. I had a case once that took out two motherboards before I figured out what was going on.

And can I recommend using the stock cooler for a while with no overclocking to make sure it isn't your watercooling thats frying your card?

either PSU or mobo. Video cards don't just randomly "die" for no reason, else you'd be seeing a recall from ATi.

def sounds like a power supply sending out bad power to me too.

I'm sorry, it was too early - no, there's no picture at all but from HDD noise and looking at the led it sounds like it's loading the OS...

You're right - specs updated. It's a 600W Seasonic, with two 18A 12V rails.

Really? And it happened over time ie in few weeks?

Sure but TBH I can only imagine two ways to get it fried by the WC: 1. no cooling - this is certainly not the case 2. bad contact somewhere - buit this would kill it probably immediately, wouldn't it?

Your just extreamly unlucky, what can I say??

RMA it and cross your fingers.

You could have intermittent shorts for all we know or any number of other things. You need to isolate the problem first and removing the water cooling variable from the video card would be a good start.

 

[T2k]

True... anyway, I'll give it another shot now as I didn't have the time Sat night nor the energy Sunday to spend more time with it...

Do you have a line conditioner such as a UPS for the computer? you could just be having horrible power.

The time between the deaths of the two boards was just a week. That was a royal pain.

Funny thing is I do, though I plugged the machie into another outlet.

Nevertheless it's back. Yipeee! :thumbsup:
Apparently my PSU and/or something in the line caused 'flatlining' - after I 'rebooted' my PSU (unplug, machine on, plug in etc) and plugged into my line coditioner the machine booted up properly. Well, one hard drive became unavailable - kinda weird because here, in the office it works fine... I guess I will rewire the entire machine (12V) or perhaps replace the PSU (which is also brand new).
Anyway, thanks for the ideas, the help!:thumbsup:

PS: in the first case - happened at the office - the VGA was totally dead, didn't work in 2 other machine, so I guess I can conclude that was a different issue...

Time to rename this thread so that it doesn't turn to unintended FUD
