Nvidia misses GTX470/480 launch targets

[tajoh111]

Of course you can. How many people overclock CPUs by adjusting voltages? When overclocking, voltage is important for stability. Overclocking reviews on graphics cards which dont include voltage adjustment are completely ridiculous ever since MSI afterburner was released. If its so easy to increase the voltages when overclocking graphics cards these days then why bother ignoring it when writing reviews on overclocking potential of graphics cards?

I dont care for what any review says about overclocking if they only used stock voltage. They can also feel free to increase volts on the GTX 400s as well if they like, but those things wont have much headroom due to their temperatures.

Heres a good review which includes voltage adjustment for the 5870:

The difference is volt changes in the GPU are not as easy to do. With some models that have the software added its easy(but these tend to be more expensive) but for the most part people don't want to do a bios videocard flash, so they can use other models software.

When you are talking about changing thermal paste on stock cooling, your not even talking about regular overclocking anymore because that will void the warranty with alot of companies. As see from the people in this thread, these 1000 mhz overclocks come at a cost. 1.35 volts is a tremendous jump in volts, in addition 100% fan is not pleasant and is only useful for benching.

Videocard overclocking has typically entailed using the stock softsoft, move up the clock and thats it. For benching you might move up the fan profile. However, it typically doesn't involve adding volts and changing thermal past or doing volt mods.

The gtx 470 are also decent clockers. Just look at golden tigers results, 20% overclock, likely stock volts.
