Hey guys,
this is my first post even though I'm following TPU for a long time :)

I have some issues regarding PowerPlay option in HD3850 BIOS. It supposes to underclock & undervolt graphic card during 2D state, but in my case it doesn't do that :( I take a look in BIOS and it isn't set properly for PowerPlay (same frequency as in 3D).
So my questions are:

1. Could I manually add/configure PowerPlay preset in it? (I have PEAK HD 3850 512MB GDDR3; it's non referent design, but should support PowerPlay!?)


2. If 1st answer is positive, how to precisely do that? :)
This is ss from RBE 1.12 ;)


I've attached BIOS, too...

Thanks in advance :respect:

It looks like it does under volt when in a lower state but the clocks dont change. I would recommend to up the clocks on the highest state and leave the lower states alone.

thx for your answer FR@NK! ;)

Could anyone tell me what Clock Info 0x (in RBE) is reserved for PowerPlay and what for higher state(s)?

and I'm curious, what frequencies does referent HD 3850 use in PowerPlay state?
