Bought a new heatpad for chip (17 W/mK) from store@mxm-upgrade to achieve better chip cooling. I get 81C on a chip after its installation.
0) Laptop: acer 5920G, T7300 2.0Ghz, 2Gb RAM, 160HDD, 1 Gb Turbo Mem, HD 3650 video.
1) How-to: downgrade to catalyst 8.10 and set clocks using AMD GPU Clock HIGHER than 600Mhz for engine and 700Mhz for memory and values won't reset back ;-) Cheers.
2) Original clocks (e600/m700) give me 4310 3DMark2006 points which is the maximum I could get with my 8600m GT 512mb DDR2. Nice.
3) Overclocked to e756/m765 @ 95 C -> 5057 3DMark2006. Without changing voltage settings.
4) After setting voltage to 1.2 (using RBE) I can push engine beyond 765Mhz, but this produces too much heat Anyway, e810/m765 @ 107 C -> 5180 3DMark 2006 points.
(new) Undervolting T7300:
1) Google for "The Undervolting Guide". There you'll find detailed description on lowering power consumtion and heat generated by your CPU.
2) My new settings for Intel Core 2 Duo T7300: x10 - 1.025V vs 1.25V, x6 - 0.85V vs 1.25V
3) Results: 62-65 C on CPU vs 80-85 C and as a result 82-88 C vs 95 C on GPU. Of course this allows more GPU overclocking, but I'd rather stay with lower temperature than continue with overlocking.
Tools I've used:
1) MobilityModder.NET 1.1.0 - to modify latest catalyst
2) ATIWinflash 22.214.171.124 - to flash bios
3) RBE (Radeon BIOS editor) 1.18 - to modify/update bios
4) HWMonitor 1.12 - log temperature
5) AMD GPU Clock Tool 0.98 - change clocks, see temp
6) RMClock - for undervolting
Collection of all ATI HD 3650 256mb gddr3 bios-s I've found is attached:
1) HP_Wistron_Vox_M86M_10.88.28354_original.rom (Original ROM of my HD 3650)
Score formula used by 3DMark 2006:
3dMark Score = 2.5 x 1.0/((1.7/GS + 0.3/CPU Score)/2), where
1) CPU Score = 2500 x sqrt (CPU1 fps x CPU2 fps)
2) GS (for hardware capable of running all tests) = 0.5 x (SM2S + HDRSM3S)
3) GS for hardware capable of running only SM2.0 graphic tests = 0.75 x SM2S
