Some help with Radeon HD 2600 XT and some BIOS tweaking? - 2008/02/22 10:46
Hello to all, I have Radeon HD 2600 XT made by Sapphire. It's an Ultimate model with a passive heatsink. In 2D mode it's running very hot and also has about 25W power consumpton in idle. I know this is normal for modern cards, but as my other components use about 55W in idle, I'm not happy with power consumption of the Radeon HD 2600 XT. So I'm looking how to make card more power efficient in 2D mode. Using RivaTuner I see that card is at 800/700MHz with 1.25V all the time.
RivaTuner Information Details...
- Core clock : 800.000MHz
- Memory clock : 700.000MHz
- Reference clock : 27.000MHz
- PowerPlay state 0 : 800MHz/700MHz/1.25V/boot
- Performance level 1 : 800MHz/700MHz/1.25V
- Performance level 2 : 800MHz/700MHz/1.25V
- PowerPlay state 1 : 800MHz/700MHz/1.25V/Overdrive
- Performance level 1 : 800MHz/700MHz/1.25V
- Performance level 2 : 800MHz/700MHz/1.25V
- PowerPlay state 2 : 800MHz/700MHz/1.25V/UVD
- Performance level 1 : 800MHz/700MHz/1.25V
- Performance level 2 : 800MHz/700MHz/1.25V
- Memory type : DDR3
The BIOS Version is 010.059.000.003. If I would know that I'd never buy Sapphire. A passive card has a raised voltage. I suppose that's great for 3D, but is that really okay for 2D mode? In the BIOS I can find 7 lines (AD10-AD70) where frequency and/or voltages are set.
Edited 2nd Line to...
F8 2A 00 70 11 01 1A 04 => for 110/700/1.05
Edited 3rd Line to...
30 75 00 70 11 01 B0 04 => for 300/700/1.20
My question is, would this enable 2D mode for my card? Should I make more BIOS editing or any other steps before flashing the card? Thanks!
