ADJUST FAN SPEED

In RivaTuner, bang the Customize button in the Target Adapter box and afresh bang the videocard figure to accessible a chat box labeled “Low-level arrangement tweaks.” Bang the Fan tab and afresh abode a analysis mark abutting to “Enable low-level fan control.” We appetite to see how far we can advance the GPU, so we charge to accumulate it as air-conditioned as possible. To do that, bang Fixed. Now, advance the slider all the way to the appropriate (to 100 percent) and bang Apply. If the babble bothers you, set the fan acceleration to a lower amount (but apprehend that you won’t be able to advance your agenda as far aback application a lower fan speed). If you can abide the fan at 100 percent, abode a analysis mark abutting to the box labeled “Apply fan settings at Windows startup,” abode a analysis mark abutting to the box labeled “Restore fan settings afterwards abeyant mode,” and bang OK.

ADJUST CORE CLOCK SPEED

Again, bang the Customize button in the Target Adapter box and afresh bang the videocard icon. Bang the Overclocking tab and afresh abode a analysis mark in the box labeled “Enable low-level accouterments overclocking.” Take the software’s admonition and reboot so that it can ascertain the absence anamnesis and amount alarm speeds. Relaunch RivaTuner afterwards the arrangement restarts. Bang the Customize button afresh and afresh the videocard figure to accessible the “Low-level arrangement tweaks” chat box. Abode a analysis mark in the box labeled “Enable low-level accouterments overclocking.” Now, use the Amount Alarm slider to activate acid the banned of your GPU’s core. If the amount is stock-clocked, alpha with gross adjustments—say, 25MHz at a time (note: The arrow keys accredit added attention than the mouse). Use a abate accession if the agenda is already overclocked or if your arrangement becomes ambiguous immediately. The abstraction is to fi nd the system’s alien limit; already you’ve done that, aback bottomward in 5MHz increments until the arrangement appears stable. Already you’ve accomplished that, abode a analysis mark in the box labeled “Apply overclocking at Windows startup,” bang Save, and afresh bang the OK button. Before affective on to overclock the memory, stress-test the arrangement with a criterion that can run abandoned for at atomic one hour. We use the two Shader Model 3.0 tests from Futuremark’s 3DMark06 analysis apartment because they can be again up to 99 times. The chargeless adaptation of 3DMark06 doesn’t run these benchmarks, but two added broadly acclimated accent tests are accessible for free: Nvidia’s GeoForms ( download ) and Masaki Kawase’s Rthdribl ( download ).

ADJUST MEMORY CLOCK SPEED

This footfall is identical to Footfall 2, except you’ll now be adjusting the Anamnesis Alarm slider. You’ll additionally appetite to bang your alarm in abate increments this time—say, 5MHz to 10MHz at a time. A admonishing figure in the anatomy of a chicken triangle with an assertion point will arise if RivaTuner thinks you’re accepting too aggressive, but this isn’t necessarily a assurance that you’re activity too far; you won’t apperceive that until you stress-test the system. If the arrangement seems stable, abode a analysis mark abutting to “Apply overclocking at Windows startup,” bang Save, and afresh bang OK. Repeat your accent analysis for at atomic one hour. If you run into adherence problems afterwards adjusting the amount or anamnesis alarm speeds, reopen the Arrangement Tweaks chat box, bang the Overclocking tab, and bang the Absence button to displace the agenda to its aboriginal values.
