Radeon Bios Editor v1.13

[Skyboat]

Week or so old already but doesn't seem that anyone has mentioned it over here yet

You're able to modify the Overdrive limits in this version now, although each BIOS is originally signed by ATI to be valid, such as ASUS' 4870TOP edition.

Latest ATI 4870 Reference BIOS here (newer than ASUS TOP): http://www.mvktech.net/component/op...func,fileinfo/filecatid,2763/parent,category/

v 1.13

• Added the checksum calculation method WinFlash uses because for some files, the checksums differ. See built-in-FAQ for more on this.
• Improved checksum balancing algorithm to capture this. This is a completely new method, so there might be some minor bugs, but it is guaranteed to not corrupt any file. Notify me on any strange behaviour.
• Added one-click update functionality for some 48x0 cards which corrects a well known "spin-up bug" and improves powerplay (power saving functionality).
• Added method for overdrive limit increasing. Still experimental, read built-in help text before using this. Power users only!
• Fixed bug with not properly displayed overdrive limits.

First attempt here

I only changed 3 & 4 here as all the other are the same, tested with ATItool and the changes worked.

Will play more tonight once ive got the new 8.8's installed.
Unfortunately i cannot take a screenshot of my CCC OVerdrive panel as im at work atm, RDP'ing to home.

also remember atitools only tests the medium 3d clock. only full screen app/games use the high 3d clock.

my god, they still havent been able to fix that problem yet?? it plagued my x1900xt all its life till i modded the bios to force the card to run 3d speeds and voltages all the time.

4800 series as 2 3d clocks medium and high, it choices the best for what your doing.
