ATI 4850/4870 voltmod thread

[Barr3l Rid3r]

damn , I loved my nice bios with 1,01V 160/450Mhz and 1,36V 850/1200Mhz...
So i have to take Rivatuner with the 8.11 .

my last 8800GTS was quite easier to handle =/- but i must say, with original bios the 4850 works really fine with the TV.

Thanks 4 help, let me know if there is a solution, please.

yes, u cant custom made your hash mod anymore...use the ready one... chage to these...


dont change any of the frequencies, just change the lower setting possible avaible to 0.93 v and 400mhz gpu... all other despites boot and UVD change only the voltage to 1.158, it will give you more precision in the pot...

use RBE 1.17...



Pros...

CCC working again on latest drivers, w/ lower voltage and frequency in 2D mode, but higher voltage on 3D mode, w/ CCC OC

Cons

limitted to 800/1300Mhz.


P.S. disable Overdrive and u can use latest Rivatuner 2.20 for benchs OC or if u need in a game... it will scale to 3D higher voltage since u change the clocks on it.

thanks 4 help. I loaded my orginal bios with RBR 1.17

Didn't change anything like hash ore something else, only frequencies and voltages. Card does well in Windows, 2d 160/500 - 3d 825/1120 - very stable.
Connect to HDMI crashes system.

Orginal:






and the modded - same but other frequency / voltage settings



so what shoud I change in my orginal bios to create a new bios with 825/1120 in 3D and a crashfree HDTV support?

Thanks for info with overdrive, installed 8.10 - overdrive disabled, overclocked with rivatuner to 850/1200 but after every benchmark in vantage - clock droppes to 625/1200 an stays there. Strange. So the first "level" benches with 850 up to 900 Mhz and the following were benched wth 625.

Never changed the Hash in RBE in the "Additional Features" tab.

I will try a new bios now, UVD Settings untouched. Perhaps card crashes caused by the UVD clocks...

yes, u cant custom made your hash mod anymore...use the ready one: method 1... select change to these settings...


dont change any of the frequencies except one!, just change the lower setting avaible (clock 1) to 0.93 v and 400mhz gpu... all other (despites boot and UVD, leave them unchanged) change only the voltage to 1.158 (NOT the FREQUANCY), it will give you more precision in the pot...

use RBE 1.17...



Pros...

CCC working again on latest drivers, w/ lower voltage and frequency in 2D mode, but higher voltage on 3D mode, w/ CCC OC
