GTX 470 issues

post #1 of 3
Thread Starter 
Hello,

I have never really had proper performance from this card. I used to have a Q9550 and I upgraded to a sweet Core i7 @ 4ghz and the issues still seem to be there. I have never played a DX9 game that doesn't stutter, they ALL do. I stopped playing Borderlands because of it. I am extremely sensitive to any graphic anomalies, especially stuttering. One thing I noticed is the Jane Nash benchmark skips like crazy. It actually seems like it loses not just a couple frames, but a huge chunk of them, when she is leaving the cave on the speed boat and the guys jump in on the jetski's they literally transport across the screen. Same with the boat as it's leaving the case right before the spin manouver. Massive frameskips, never got better with ANY driver or changed at ALL when I upgraded my system. This really makes me think my GTX 470 is messed and always has been.

The thing is, I can never get a stable framerate from this card. I ALWAYS get stuttering. Even with every part in my system at stock.

My question is, has anybody seen or heard of a GTX 400 series card performing like this and an RMA fixed the situation? I do not know what to do anymore. My system is incredibly powerful, I should NOT be getting stuttering. I have issues in Crysis 2 that NO ONE else has, the card will play fine, start to stutter and the framerate becomes jerky. Wait a few seconds and the SAME scene is perfectly fluid. This is driving me insane.

I bought this card about two weeks after Fermi came out, it is without a doubt from the first batch. Any ideas here guys? I am sooo sick of this crap.

System is in my sig. Thanks for looking!

*edit*

Just for kicks, I loaded up optimized defaults in my BIOS and set everything up for stock operation.

And what do ya know? Stuttering has stopped in Crysis 2. I am going to test more games. This worries me though, I really do hope it's a PSU issue. Not my settings hopefully, I worked very hard to get it stable. 24hrs prime type stable.

Any ideas at all? Lost here myself.

*edit 2*

Voltages just for reference:

CPU VCORE: 1.312v
CPU PLL: 1.5v
QPI/VTT: 1.435v
QPI PLL: 1.16v
IOH: 1.12v
ICH: 1.02v
DRAM: 1.70v

Something is clearly unstable, also you have a LOT of voltage for your GPU, you should be able to do those clocks at 1.087 or lower easily. I would first put it back to the original bios, put everything back to stock clocks and go from there.

Did some massive testing.

Seems to be a power issue. This is what I have figured out.

System @ 4ghz with GPU overlocked, stutters.
System @ Stock with GPU overclocked, fine/no stuttering
System @ 4ghz with GPU @ Stock fine/no stuttering

From what that tells me, my PSU is insufficient. Cannot power my system overclocked as well as the GPU. Would you guys concur?

I even replaced the wall socket, just to be sure. At least the new socket is much better.
