ATI 3850/3870 Voltmod thread

[ownage]

I bought a cheap HD3850 256MB a month ago, and i did some mods on it

Vgpu Mod
Accelero S1 + slow 120mm fan, really silent
3870 Ram heatsink
Sawed of VRM part of the stock heatsink


With 1.45V i can reach 920 mhz stable ( 15min furmark 1280x1024 8xaa ), but the temperature gets to 70°, with atitool my the max temp is about 55°, anyone else with a Accelero S1 and 38*0 that can test at my settings ?

I'd like to go a bit higher on the core speed, but i have no idea what the max safe vgpu is ( 1.5v ? )
I'v read here about replacing a few condesators for a higher overclock, but i have no idea what cond. should be replaced, and the amout of µF , any help with this ?

And my last question, would i benifit from a ram vmod ? I'm running my ram at 1000mhz now, max 1050mhz, going from 800->1000 didn't matter at all, is there really no ram bottleneck on these card with a core <1000 ?

I'm using a Sapphire hd3850 256mb for a month now. 1.53vgpu and 950mhz full stable. I probably can lower the volts, but didn't test it.
Max was 1053mhz benchable @ 1.83vgpu (OVP sucks)
I don't know if 1.53vgpu is safe or not, time will tell

My ram is 1000mhz stable without heatsinks or active cooling, just naked ram.
ram vmod would help but a bit to much and the card will die.
