#HIS ITURBO OVERCLOCK DRIVERS#

Added Catalyst 6.1 - 6.5 drivers detection. Updated databases for Detonator and ForceWare drivers.

#HIS ITURBO OVERCLOCK DRIVER#

Added ForceWare 84.xx and 87.xx driver families support. Fixed abnormal negative remote temperature reading for temperatures above 64вЊ in ADT7473 plugin. Saving driver-level overclocking profile when Standard 2D or LowPower3D performance level is selected and subsequent attempt to tick 'Apply overclocking settings at Windows startup' or to save startup settings no longer results in saving 3D startup clocks for this performance level on NVIDIA GeForce FX and newer boards. Restored Catalyst 5.10 / 5.11 compatible SoftR9x00 patch scripts, which were erroneously not included in the previous version's distributive. You may disable 'Allow VGA BIOS script parser for clock frequencies programming' option to make RivaTuner's memory clock frequency control working even on the cards with such VGA BIOS. However, unlike these tools RivaTuner optionally allows you to avoid VGA BIOS script parsing and use hardcoded memory clock frequency initialization codepath for X1000 family display adapters. Due to this reason, you won't be able to overclock memory using the tools mentioned above until ASUS fix their VGA BIOS. The problem is located in ASUS VGA BIOS and caused by incorrectly functioning memory clock frequency programming script, which is parsed by all these tools during memory clock frequency programming. The problem is not RivaTuner specific and also echoed in ATI OverclockerX1K and ASUS SmartDoctor overclocking software. Attempt to change memory clock frequency on ASUS X1300 PRO series may cause system to hang with corrupted image on the screen.

#HIS ITURBO OVERCLOCK MANUAL#

You must disable manual overclocking in the Catalyst Control Center to get RivaTuner's driver-level Overdrive 3D clock frequency control working. Due to specifics of ATI drivers, third-party overclocking settings done by tools like RivaTuner, HIS iTurbo and Sapphire Trixx are overridden by Catalyst Control Center's Overdrive settings.

The bug is fixed in the Catalyst 6.5 drivers suite. The problem is not RivaTuner specific and is also echoed in ATI OverclockerX1K, HIS iTurbo and Sapphire Trixx overclocking tools. RivaTuner's driver-level Overdrive 3D clock frequency control will not work on the Catalyst 6.4 driver due to ATI bug. To reach the same clocks by relaxing memory timings you may enable 'Allow VGA BIOS script parser to tune timings on memory clock change' option. However, it will result in lower reachable memory clock too. Due to this reason, memory overclocking via RivaTuner results in much better performance comparing to the same memory clock set via ATI's overclocking tool. Unlike ATI's own overclocking tools (WINCLK and its' derivatives), RivaTuner doesn't relax memory timings during changing memory clock frequency on RADEON X1300 / X1600 / X1800XL series by default.
