When is XFX going to fix the prob w/ their 7900GT/GTX cards?

[Spiffypants]

Seriously, are we ever going to get an answer? I've gone through 2 bad GTs and now my GTX is starting to go bad. NO overclocking, stable voltage, ideal cooling/airflow. Too many people are having this problem for it to be a fluke.

[werty316]

I didn't know the 7900GTX had problems; I thought it was only the 7900GTs. The 7900GTs have some heat issues with the voltage regulator getting way too hot. I think it has a max temp of 70c but some users are reporting the voltage regulator getting as high as 80c.

I don't want to mention anything specific but some companies have done something about this problem while others seem like they aren't trying enough to help consumers.

Give this a read:

Have you trouble-shooted every component, Spiffypants? 'Cause to have 3 defective video cards seems to be more than bad luck... perhaps a bad component is at fault? IE: PSU? I only say this because I lost a HD because of a bad PSU...

I have troubleshot everything in my computer, 10 times over. I've researched the hell out of this, and many, many other users are having the exact same symptoms as me. The cards work great for a few days, then slowly begin to deteriorate at a fundamental level. The GTX did last longer that the GTs did, but eventually began to succumb. I know its tough for me to prove that this is not because of my own wrongdoing, but you've got to trust me on this.

[Kougar]

Well, do you have another computer you can test the card in? And would you please define "go bad"?

Did you double check the PCIe voltage settings were set correctly in the BIOS? I suppose it is theoretically possible that a bad mainboard could be overvolting your cards... idle supposition mind you. But three in a row all exhibiting the same problem, one of them a different model, is just to much of a coincidence for me to let go.

[Scott]

Interesting though, if consider my staff have the XXX cards of these which are overclocked the highest and we have not had any issue.

[Bio-Hazard]

There are a bunch of folks on different forms with numorous failures of their cards, both 7900GT's and GTX's. I have no clue exactly what the problem as even the modded cards that one company is having problems now. It may be that they are just OC'ing them to high and claiming foul. But I have read of people RMA'img 5 or more cards. Mine is doing good so far at reff speeds as it should, and different games at-up at different OC's. But like I said, at default settings, everything runs and all bench marks are completes cleanly.

Wow, that really sucks Spiffypants :( I cannot fathom receiving 2, let alone 3 defective cards :( I do hope that XFX Support can help you... the whole 7900 line is suddenly not looking as good as claimed... hopefully NVidia/XFX/EGA/BFG/etc. WILL fix this problem, else this could be bad for business :(

Ive noticed problems with the 7900gt/gtx cards with users with weak psus. I hate to tag it to something like a psu, but am interested to see what you have (just trying to test my theory here).

[werty316]

Having ample power is something alot of users ignore with it comes to high end video cards.

My XFX 7900 Gt is faulty, and my PSU is an Enermax Noisetaker 600W.

[zachig]

I guess you just "fell" among those who got unlucky with their 7900GT cards...:( Have you tried contacting XFX already?

If so much people are complaining about faulty 7900GT cards (especially those that come pre-overclocked from eVGA, BFG and XFX), I wonder why these companies don't do something with it to help their poor customers...:confused:

[werty316]

Because its not there fault since they didn't design and build the cards. It just so happens the 7900GT can't the factory OCs.

Well, I think I'm getting owned. LDLC is where i bought my card.

Which Enermax Noisetaker 600W do you have? This "wannabe 600W POS" (http://www.xoxide.com/enermax-600w-eg701ax-sfma2-sli.html) or "this other one" (http://www.xoxide.com/enermax-noisetakerii-eg701ax-600w-sli.html).

teh first one. active pfc.
why do you say "wannabe" 600W ? it sucks ?

It is, be expecting it to have problems exactly as STATED HERE (http://www.techspot.com/vb/topic23368.html), and other symptoms besides.

Its weakness is 5V and 3.3V power taps, which normally are only apparent to those with experience designing switching power supplys.

That might explain the problems you're having, although the video card uses the 12V and not the 5V and 3.3V rails...:???: :roll:

I would try running the Video Card with a different PSU, just to verify it's really not the PSU...:wink:

[Free_Free]

I think an almost bad PSU can't explain artifacts. That's just my opinion. I didn't experienced any weird reboots or sumthin. My system is stable, OCCT certified.
I chose this PSU because it was recommended by the DFI Street.
And, according to Smartguardian, my PSU delivers a very stable power (dunno how to say it in english lol).

[zachig]

So the only cause remaining is your Video Card itself...:( (probably...)

I can't think of something else...I guess you'll have to try and RMA it...:???:

[Free_Free]

Already done, they ran 3Dmark06, 03 and ati tool for 6h each and they didn't get ANYTHING wrong.

Are you sure you are an "Electronics Engineer" as your profile said?

Here's a tip to verify vid cards not using 3.3V power tap - simply cut the 3.3V logic power trace to the PCI-e slot the vid card is in, then verify for proper functionality.

Alternately, you can also read up PCI-e power requirement specs for vid cards, which a while ago was 3A at 3.3V for PCI-e vid cards.

[zachig]

Hmmm...that's really strange...:confused: :???:

Have you tried different drivers? Which drivers did they use?

Oops, sorry...I guess you're right...And yeah, I'm an Electronics Engineer, it's doesn't mean that I neccesarily understand how Video Cards work and/or which voltage they use...:lol: :wink:

I will ask them when i'll go to teh shop...

Its probably more useful if you did what the last guy had done in the link I gave above. The below is an accurate descriptive behavior characteristics of a POS supply.

"When I look at ASUS PC Probe while the PC is idle the voltages read: 12.5; 4.865; 3.296; 1.68. I recorded the voltages and started playing BF2; it rebooted when I went to quit the game the last voltages shown on the history were: 12.736; 4.73; 3.264; 1.696."

Yeah...you can try this is well in order to diagnose the problem...

Anyway...GOOD LUCK...keep updating us when you get back from the shop...:wink:

When the voltage rails readings and fluctuatiions are that bad it is a clear sign of a POS PSU.
