Overclocking/underclocking?

mkonjibhu · 01-31-07, 05:30 PM

I was wondering if it makes sense to Underclock 2D settings in Rivatuner so my card (6800GT) would Idle at a bit lower temps, but overclock set just for 3D apps so once I load up the app, the clock speeds will adjust from under to over clocked.

The 2D settings are already underclocked and undervolted and underclocking even more might result in unpredictable results. Try and see though, because just a couple of days ago, I got the same idea with my CPU.

I normally idle at 32-34c depending on ambient. I also normally have my fans running at 70% at idle. I grabbed RMClock and enabled Cool&Quiet in my bios, configured my CPU to run at 1180MHZ @1.18vcore idle, 2950MHZ @1.39vcore max with RMClock.

My idle temp is now 27c with fans at 50% which means they can hardly move dust, much less air. Very quiet! My fans automatically ramp up to 100% based on mobo (PWM) temp, then go back to 50% rpm when things cool down.

Sorry for the derail, but RMClock is a really cool program! You may want to check it out since you are interested in saving energy or quieting your rig.

edit:

You could mod your vid card bios for a lower 2D clock with nibitor or underclock just your 2D with rivatuner as well.

I already used Rivatuner to adjust fan speeds based on my temps. Scales from 53%/55%/75%/90% depending on the temp it reached. I just figured if I underclock the 2D a bit, it could put a bit less strain on the card or PSU since I leave my comp on most of the day.

I underclock when not in use.
I've had no issues wrt stability (that I know of) and it saves power, lowers noise, etc. when not gaming.
