Evga Voltage Tuner

[jaredpace]

I've been using Riva Tuner to adjust voltage on my GTX 260. Running clocks at 706/1501/1306, on 1.15V (up from 1.13V stock),in COD:WAW I'm getting a solid 60 fps with V-sync enabled, all eye candy enabled, run at 19x12 resolution. Other games behave similarly. I also force triple buffering with Riva Tuner. How much more could I get with a GTX 280 or 285?

Just being able to adjust voltage to stabilize clocks helps these 65 nm cards render at the same level of the higher cards. I really don't think that you'll see all that much of an improvement on the higher level cards as compared to the 260's. With this voltage tuner, EVGA just extended the life of the 65nm 260's.

The original 192 shader / full copper / 14 layer PCB / volterra VRM / 4 phase Pwr / 65nm gtx260's are obviously the most well built & robust and ATM are cheapest:

At the end of last year, GeForce GTX 260 became the first one of NVIDIA GTX200 series graphics cards to use 55nm processing technology. It featured P654 reference design, which cost less than earlier P651. The number of PCB layers reduced from 14 to 10, and it has abandoned the expensive Volterra chip to cut cost. Quite soon, the third-generation GTX260 design plan with codename of “P897/D10U-20″ will be also surfaced.

The schedule drawing of P897 PCB design
According to the P897 design plan that NVIDIA sends its partners, it uses 4/6 phase NVVDD power solution ADP4100. It changes FBVDDQ power solution from 2-phase to single phase. And the MOSFET package has been changed from LFPAK to DPAK to save cost. Another noticeable change is the PCB layer decreases from 10 to 8. The length of PCB keeps unchanged, while the height of it is reduced by 1.5cm. In order to cut cost further, they will change DVI connector, crystal and probably change BIOS Rom from 1M to 512K.

But for the GT200 and NVIO2 chip, you might mistake GeForce GTX260 of P897 PCB design for GeForce 9800GTX+ (as they look so similar). Compared with P654 design, P897 GeForce GTX260 is expected to save cost of $10 to $15, which will undoubtedly improve its competitiveness. According to our source, this product will be available in the third week of this month.
We also manage to get some pictures of new GTX260 from a Chinese manufactuer Colorful. Coming from their iGame Series, this GeForce GTX260 card is designed based on P897 PCB design. They have just changed the TV-out connector to HDMI and added a set of overclocking jumper.

If you can still find one.

OOOPS....Get them while they're hot
