I don't know of its faster but i did that hex mod
on a 875/1200 bios downloaded somewhere
Different people are running it now !
like Extera's cards are running fine :)
And hits the 25000k in 3dmark06 with a Yorkie
No need for hex mod!
You can edit the bios clockspeeds with this:

Ive never been able to get that 3870 BIOS editor to generate a valid BIOS....atiflash and winflash both report invalid VBIOS :shrug:
Hmm..bios editor worked fine for me. I flashed both my cards to 890/1290 just fine. The problem was teh card performed well in single.. but in CF I had to drop the speed. Trying to find the max speed right now.
When you guys OC your CF.. how do you adjust the speeds on both cards? Is there one place where you can adjust both cards at the same time, or do you have to adjust each card separately, like the fan rates?
Ton
you have to adjust clocks for each card (CCC or Rivatuner)
regards
No , just the first Two adapters (Plug& Play Monitor and the Predefined Monitor)

you can choose in Overdrive the card you want to Overclock

Card1 >> HD3870 SyncMaster
Card 2 >> HD3870

Mascaras,
Thanks for the screenies :) I will give it a shot tonight. I think i was benching asymetric last night. that would explain some of the "Weirdness" I was encountering :)
Once I get the max CF Speeds in place, I can try to do the vMods next :D

another thing , To crossfire work properly the Catalyst A.I must be in STANDARD Mode and CF Enable in CCC

950Mhz

i think Auto-Tune not working OK and its very dangerous , mainly for memory ..........

Does AI have to be in standard mode or just enabled?
standard or disabled.
Crossfire doesn't work well with advanced AI enabled? I tried two HD 3850s under Vista x64 @ 730|1000 with Overdrive and they did 16.5K.

The "unkown mobo" is a BX2 :p: Guess I will go back and try standard.
They recommend that AI is either disabled or in standard mode.

(Sorry for stealing your picture mascaras)
I ran it again and it was higher
http://service.futuremark.com/compare?3dm06=4422084
16761 vs 16557 for the first.
Btw, do overclocking in Crossfire with Vista 64bit work well now?
Thanks guys, that cleared things up.
@Blacklash, was that run in standard mode or disabled for AI. Disabling the AI should give you the highest score.
Might be me that have some strange issues here... I have two 3850 256mb and running CF. I can only clock one card with rivatuner with this BIOS. Also, I can not clock any card with CCC.
Is there any solution for clocking both cards exept with flashing BIOS with fixed clocks?
Thanks for sharing though!! :up:
