Hey guys. I'm having a little issue with performance on my GTX 280 card. It's currently using about 6.23v in Speedfan which is dangerously low, though the PSU is fine and is within +/-5 on all rails. AFAIK it has enough ampage at 20 amps on the 12v rail. I've also tried using different rails such as the molex connectors on an adaptor that came with the card. I'll leave my specs at the end of this message, any input would be fab.
AMD Phenom X4 965 @ 3.4 Ghz (1.250 volts) sometimes at 4Ghz during colder weather, I'm on air.
Yeah. Real-world performance isn;t what I'd expect from a GPU like this one. Maybe the card does actually suck and I should upgrade. Maybe the games just don't utilize the card well. I don't know. All I know is that it doesn't even come close to what I see in other people's benchies.
I most definately did. I even had a guy who builds them for a living confirm that I did. I'll get a new card and then RMA this one and see if the warranty still stands. If it does and it's defective I'll get a refund, or a new card and then sell it.
The card isn't using 6.23v. If your 12v rail is showing that number with a software program, you should test it with a voltmeter/different program. If your PSU isn't putting out 12v, then the card is throttling its clock speeds to be able to run with the power its getting. The problem might be with your "850W" PSU and not the card.
Tested it with a voltmeter and it's all within +/- 5. My bios also shows the actual output with the same readings. Also, the clock speeds don't seem to be throttling in GPU-Z but again it could be inaccurate with it being software.
The card was £275 when I bought it and I can't afford another card any time soon, so yeah, if there's a possibility of getting it working optimally it's worth it. If I *am* forced to buy another card, it'll be ATI. I've since learned that nVidia are stupidly overpriced.
