[SOLVED] 6900 series negative CF scaling

post #1 of 23
Thread Starter 
Hi guys,
I'm quite lost.... :s
When I first got my rig,
One of my cards was dead on arrival...
So: I've sent it to RMA and got my new one in a couple of weeks.
However:
I think this card is broken AS WELL..
Why?:
Cf doesn't work...
I'm getting negative scaling ( from one card 50 fps to 2 cards 30 fps)
I'm also getting chess patterns... ( for example in the BF BC 2 server browser.
I don't know if there is a card really dead because they work 'fine'...
One card gives CTD , one doesn't ( One card physically installed...

I'm just soo lost...

I've tried so far:
A clean install
Different Drivers
Different CAP's
Stock Bios ( tested before first flash , no fix)
Unlock Bios
Should I try underclocking?

Pls , some on give advice on what I should do...
I'm thinking of selling this to pieces of crap and investing an other 500 EUR , and buy 2 3GB 580s... :s

Not so helpfull tread...

Thx in advance
Grtz
Xioros

EDIT : my cards are 2 ASUS 6950s ( sig )

Yes, I tried both cards individually.
Both work fine individually.

yes, I tried other games as well , only synth benches like 3D mark scale...

Just tested my card usage:
F= first card
R= RMA card

First/second slot

F/R CF enabled Fload= 70% Rload= 20 %
F/R CF disabled Fload= 100 % Rload=0 %

R/F CF enabled Rload= 80 % Fload= 0 %
R/F CF disabled Rload= 100 % Fload= 0 %

R/F causes CTD
F/R doesn't

Anyone who know what this could be?

Chess:
It appears in the server browser and sometimes in game

You're posting some (seemingly) contradictory things here ...

One card gives CTD , one doesn't ( One card physically installed...
seems contrary to:
Both work fine individually.

and similarly

R/F CF enabled Rload= 80 % Fload= 0 %
R/F CF disabled Rload= 100 % Fload= 0 %

seems contrary to:
R/F causes CTD

So, to start, let's get clear on what exact scenario is causing CTD

Also, what game/test gave you the above % usage numbers?

Catalyst AI is NOT disabled, and you are running in full screen mode, correct?

Aside from what you've tried, I would also try:
1) Different x-fire bridge
2) Flashing the same, stock bios on both
3) Reinstalling Windows
4) Trying them in a different machine

Was the card you got from RMA a refurb, or BNIB?

The second card crashes randomly in game, I tested this when it worked for a couple of mins

So, to start, let's get clear on what exact scenario is causing CTD
The bad card?
Also, what game/test gave you the above % usage numbers?
Battlefield BC 2
Catalyst AI is NOT disabled, and you are running in full screen mode, correct?
I'm running full screen, and checked load history,
I'll try Crysis tomorrow
Calalyst AI: where do I even find this setting?

Aside from what you've tried, I would also try:
1) Different x-fire bridge Trying tomorrow
2) Flashing the same, stock bios on both Trying tomorrow
3) Reinstalling Windows already tried, didn't fix
4) Trying them in a different machine don't have an other system to test the cards with...

Was the card you got from RMA a refurb, or BNIB?

The RMA was a complete new card , with a different serie number.

I get the chess pattern when enabling vsync in Eyefinity, albeit not as an absolute result. That is, some games do not demonstrate this glitch.

Try running the GPUs off of the NF-200 slots for the Maximus. I see near perfect scaling in 25/30 games tested with the Gigabyte high-end equivalent of your board. Lift your overclock a tad - may not be necessary, but can only help. Also, I'm getting the impression you are testing with BF:BC2 only? Shut off your vsync.

As for BF:BC2, find the settings or gamesettings.ini in your My Games folder. Change the "renderahead" settings from 2 to 3 - this resolved jitter in my experience. Use Radeonpro to adjust variables inaccessible via CCC. For Crossfire, I've found notching up "flip queue" to improve performance. Try bumping your memory clocks, perhaps?

I'm having this on CF with Eyefinity/no Eyefinity and Vsync/NoVcsync

NF did not fix, I'll oc higher when I get home

As for BF:BC2, find the settings or gamesettings.ini in your My Games folder. Change the "renderahead" settings from 2 to 3 - this resolved jitter in my experience. Use Radeonpro to adjust variables inaccessible via CCC. For Crossfire, I've found notching up "flip queue" to improve performance. Try bumping your memory clocks, perhaps?

Installed radeonPro, Could you send me your profile for the game?
Might work for me...

I'll Try ocing my card when I get home
