Hi Everybody!
News from mmaakk:
I did replace 2 ATI cards (2x HD 3870) from one of my PC's. I bought 2 new cards - nVidia Palit 9800 GT 512Mb DDR3. I was hoping to get at least 6K PPD each, looking that I'm doing 6.4K PPD with my 8800 GTS G92 with OC, but didn't work out well. The 9800 GT at stock values - 600/1500/900 - was getting around 3.7K PPD. Than the nightmare started when I tried to OC the cards. I found some reviews like "Gigabyte 9800GT 787/1863/1075" so I went for it!!!
Resuming the story... my actual values
Card PCIe 1 = 684/1579/900
Card PCIe 2 = 714/1618/932
PPD: 4,411.91 per card :shadedshu
I was always an ATI guy. So I can handle OC, BIOS mod, etc... very well. But with nVidia the only tool I'm using is RivaTuner.
PLEASE I NEED SUGGESTIONS TO A BETTER OC FOR THE 9800GT. EVEN GPU OVER VOLTAGE IS WELCOME IF NECESSARY.
I got so pissed with all that, so just to get things better I'm folding now with my Gamer rig too (2x HD 3870X2). FahMon says 22K PPD total - check attached pic.
Mmaakk, I want to start be saying thank you for you efforts and contributions to TPU! I have the answer to your problem. GPU2 is very shader intensive. In Rivatuner, you must un-link the shaders from the core in the o/c'ing window. You want to take your shaders into the 1800/1900+ range and leave the core in the low 700's. Memory is not as important, but a small boost won't hurt(850'ish). Fiddle until you find your highest stable overclocks. Good luck and watch your PPD climb.
