7970 Matrix Platinum - safe mode all the time

[czeslaw]

Hello,

I've run into an issue with my graphic card.
After building my pc, installing windows 8 and drivers my card was flashing green all the time. I discovered that it was connected to Asus EPU engine, what I described here: http://rog.asus.com/forum/showthread.php?29501-Matrix-Platinum-EPU-Engine&country=&status=

Since then my card was doing perfect. Today I've opened my chassis, removed RAM to try it with different PC, installed it again and now my card is in constant safe mode (led indicator flashing green). GPU Tweak ask me each time after boot to "recover my graphic card" but after boot it's still green !

Please help ....

Can it be that something happened to my psu and now graphic card can't work normally ?
Should I try holding the safe button while pc is booting ? Flashing card's bios ? Resetting the motherboard's bios ?

OK there's a new symptom. MATRIX makes this "buzzing" sound, when game starts, stops just in the second when I exit the game!!

It's not from the fans!

Hm... I can hear some "buzzing" from my Matrix Plats too... it's rather a high pitch whining than buzzing, though... - it's happening when I push the VRAM over 1900MHz... but at stock settings it is not happening...

For some reason, the sound i get is stronger in 3DMark03...

Till now my matrix wasn't making sounds like that and I've changed nothing. It's on default settings. Entering game starts the buzz, exiting stops it.
It's quite loud, louder than my fans, so it's something like 10-20dBA. Not acceptable 😞
I'm reading about it right now, googled "7970 buzzing". Lot's of people are having such issues with gpu's but as I remember matrix was supposed to have best capacitos - BUZZ FREE 😞

Are you sure that it's from the Matrix and not from the PSU?

[czeslaw]

Yes - 100%, I switched to another psu to make sure it's the matrix

I suffer from the same problem With My matrix 7970 platinum And MAXIMUS V FORMULA.
I've tested This Graphic Card On Asus Z77 vl-x And It works Without any problems

Mine just returned from the RMA, I'll try to pick it up from my distributor today ... I don't know if they replaced or repaired it. I'll keep you informed 🙂

Are your card's capacitors "buzzing" when on load ?

I see now! Didn't paid attention to the Z77 part... - unfortunately I don't have that mobo to try the Matrix cards on it... 😞

Hm... the platform could be a problem?

Which mobo is the "Asus Z77 vl-x"? The new Maximus VI Extreme?!
