Setting up a 2D profile for the G80, Worth it?

Ok so you all remember the R600 power tests I did, well now I have done one with my G80. I wanted to see how much I could save by setting up a low clocked 2D profile (290/675/900) in Rivatuner, rather than having the card run at the same speed all the time (575/1350/900)

These were the results (test was done with all applications shut down and PC running totally idle both times)

2D Normal (575/1350/900)

2D Modified lower clock setting (290/675/900)

The temperatures also reduced by 4-5c which means you could possibly turn the fan down to compensate and have less noise?

To do this it's very simple,

Grab Rivatuner 2.05

Go to clocking tab

Click enable driver-level harward overclocking

Select Standard 2D

Now reduce the core clocks all the way down leaving the memory alone

Save in a profile

Tick "Apply overclocking at Windows startup"

Jobs a good un!

The gains are minimal when compared to the R600 where there was a fairly big saving to be had, whether this is worth it you'll have to decide but I have seen people asking how much power can be saved so there you have it really. Im curious why NVIDIA didn't do low clocked 2D profiles anyway?. Maybe they thought there were not enough gains to be had?

Anyone know how much 15w would save you per year? :D:p
 
Depends how long you have your pc on for and in 2d mode.

If 10 hours per day, you save 55kw per annum so about £4-£5

it looks like the power saved is being used to light up that fancy display. :p

Win win! :D

I actually have another meter to monitor power which can measure the kWh used by my PC. Tommorow I'll plug it in and compare them to find out the real energy cost savings
 
I always run a slower 2D since the 6000's (Memory wont work in 8000's your stuck with same 2D/3D and nothing in bios cant change this).

I did it as there is no need for my Core to be 700mhz to type this here, and I want all parts cooler so fans can be slowed to 50% and PC still not get too hot, as I like it quiet outside of games.

Spot on. I have done it since the X1000 series. The benefits can be larger than you think especially when running on air and case temperatures can be offset by little things. It all counts I guess.
 
Also considering my rig is using 280w of power at idle is scary anyway :eek: comparing this to the likes of my 360 which uses around 130w :D
 
I used to run a APP called "8rdavcore" that let you control Profiles for the CPU/Mobo (bascially every settings inc all volts and even Mutli on some Mobo's) and didnt crash it when applied in Windows (ignore Asus AI Tuner).

With 1 press of mouse have 1 of the 3 profiles I set up changing inside Windows without crashing the PC.

1 was low power for running overnight downloading files and ran low FSB+all Volts so CPU was like 1.6GHZ and ran so cool fans were set really low RPM.

2 was normal power for everyday use.

2 was full power with highly overclocked FSB+all Volts for gaming etc.

Again it was done not to save power but make PC run really cool+quiet.

Interesting I'll look into that (considering speedstep can't change the voltage with OC'd CPU's so was pointless, at least not on my board)

Why don't you use it anymore?

What spec is your machine? My 8800 runs at (core/shader/mem) 256/600/400 2D 54%fan and 500/1200/800 3D 60-72%fan.

What is the Zalman fan controller like? I heard there were a few reliability problems with them.
 
Well its old and only supports older Mobos same as Speedfan (about NF2 area models).

Asus AIbooster 99% of times locks my PC (about 50% of time on Crosshair but had more settings than any mobo Ive seen inc this one).

Clockgen works sometimes but dont have profiles and can lock up PC.

I dont like the Auto clocking APP's be it AMD or Intels, I prefer a APP I set up and then make 3 profliles and can ideally run from inside Window without crashing PC.
