:( 295 GTX problem
 
I bought a Galaxy 295 GTX a few months back.

I have paired it up with a 850 Antec PSU.

My CPU is 1 Q9650@3.8Ghz with a Asus Formula Maximus SE motherboard. All in a Silverstone TJ-10 case (and all open)

Recently when I game...and I only game Age of Conan. My monitor blanks out even though, HDD lights are flashing etc indicating the computer is working.

However, I have checked at the back of the case and I saw a red led light up. After searching through the internet, I read that it might be PSU issues, so I have ensured that the two connectors connecting to the 295 GTX were from separate lines from the PSU to deliver enough juice but, I still have the blanking out and red led lighting up when playing Age of Conan.

Now, I don't think it is a PSU issue as it seems my 295 GTX is escalating to 110 degrees celcius with fan at 100%!!! This is with the case open...and I am even underclocking the card by almost 150 mhz in all departments and the temperature is still above 110 degrees. Cleaned it out as much as I can with brush. Air con cooled environment and still nothing and the monitor just blanks out with red led lighting up at the back of the 295 GTX?

Is the temperature rising to 110 degrees and above responsible for the blank outs? If it is....anything I can do? I invested a lot of money into this card and I would like to use it as intended...for gaming without any issues?

Can anyone please offer me any advise what to do as I am at my wits end. Thank you in advance

I think jAkUp would be the one to ask...as he deals with these cards on a daily basis.


Good luck.

That red light means one of two things. Either it is overheating, or PSU issue. Sounds like it might not be making contact, you can try taking it apart, but it is probably best to get it replaced.

Wish it was that easy mate. In Hong Kong, you get a 7 day return thinger from the shop you bought it, and then after that you get the inconvenience of trying to locate the distributor and giving it to them to replace...and i went through that before for a Abit nForce2 mobo.

i would also try uninstalling the drivers and reinstalling the latest versions

double check your two power cables again that they are properly connected

I have seen red light issue occur sometimes when unstable power currents make it to the GPU. As jakup said. I'd watch the tempatures first. But it could also be an unstable current across your 12V+. The 295 is a bit pickier about this than other cards I have used.

The thing is Chris, GPU-Z reports temps rising to 105 degrees celcius and above when I try furmark or Age of Conan! It might be temperature related as I have made sure the 2 connectors are fed into the 295 GTX from different lines. I wish I had the finances to watercool it but, I don't.

This blanking out didn't happen before when I was gaming hours on end....and it only started happening a month ago.

RMA process in HKG is non existent....and I am essentially stuck with a semi dud card....

If it is bad contact. Then it possible to take the card apart. The GTX 295 is actually much easier to dissassemble then the 9800GX2. But it voids warranty. The problem is. Its not always easy to get better contact. And dual PCB cards can be difficult to put back together ((lack of hands)).

I might suggest putting a can of compressed in the fan blades and letting the tube slide deeper into the heatsink and try to blow anything that may or may not be blocking it. When it reaches it extremely high tempatures. Can you feel an incredible force of air coming out the heatsink thats exposed? ((should look like several grates)). If you're not feeling much air being released you may have a jam up in your ventilation system.

Oh and is your case closed?

Might help to have a duct/fan to feed cold air towards the intake of the card, and maybe a fan to suck the worm air expelled from the card away from the case. I've done this before for a laugh and it worked really well; dropped 10*C+. Hope you get it sorted Muya :).
