The bullet has been bitten [2nd 6950]

Didn't know you had to do this, didn't see it in any threads I came across

you not looking in the right places then
that quote i added up above is from an answer to the exact same question i asked over the new year

Off topic.. Why you selling your 6950 crossfire setup out of interest

moment of maddness, it happens from time to time
 
damn, i was reluctant but ive bought the asus 2gb 6950 card

hopefully it should allow everything produced for a while to run smoothly maxed out,

and if it turns out to be not worth it, at least it helps heat my room lol

a few questions .. maybe stupid

- running 2 monitors, do i plug both into one card, one in to each or does it not matter?
- is it a good idea to underpower these in CCC to save some heat? obviously the full power will not be needed for games to run smooth
-any other matters i should be aware of? [new to multi gpu]
- maybe i should flash the bios, but use bios setting 2 until i need the extra?

wow, you joined in January and almost 1000 post already :p
 
yeah January last year, and believe it or not i have a gf lol

my first pc build and i have lots of questions

yep AB has voltage enabled, i found that myself after i posted, thats unlocked correctly
 
Yeah the latest one 3.7 works and it allows you to select multiple sensors, I use one for each card

Also I've been having bsod with afterburner, do I have to disable ulps in windows registry to get it to overclock the cards?
 
yes disable ulps
u got a guide for that ?

Go to registry and disable Ulps:

[HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Cl ass\{4D36E968-E325-11CE-BFC1-08002BE10318}]

and change "EnableUlps" to 0 under the 0000 and 0001 or 0003 keys.

yeah ive changed registry before,

like before the main bits im unfamiliar with is bios stuff and overclocking [as well as being over cautious cause one wrong figure followed by 'enter' ruined hardware]

id like to say thanks to all the people who have helped me out with this in this thread. :)

also as far as i know thats the last thing i have to mess with to achieve this

al4x: In afterburner config (the same one that's in your screen shot above) you should add this to it

ok if powerplay doesnt work im using beta 7
have applied the fix and its all working now, the BSODs no no longer happen, everything in afterburner works
im clocking each card in non crossfire mode as yet as i dont know if you can do it with crossfire enabled, [im guessing you can]

i knew the g15 mini lcd display would come in handy for something.. amd its displaying the stats of each card [V,clock,temps] :)

i guess apart form the crossfire or not when OCing thats this done!


thanks to everyone for walking me through this, i expect ive tried your patience at some points! :)
 
ok this is not the end of it, now one of my gpus is at 100% usage with no overclock just pressed apply in msi afterburner with a tiny voltage tweak
 
Sometimes I think this has not been worth it

Now msi boots at start up but one of the 2 cards goes to 100% gpu usage,(that's what msi is reporting along with temp increase)

I then load gpu z and it drops back to zero like it should but card one doesn't then click any higher that stock 810 and 1200

Driving me mad.. I don't want to have to boot gpu z every time I load the pc

to elaborate further..
with CF enabled
Card one will not go above stock 1.0mV, and stock clocks, soon as i click apply in AB it just defaults back
card 2 will but sticks at 100% GPU until gpu Z is activated
with the above opening a 3D app .. ie a game.. card 1 jumps only to 810/1250 but card 2 does show what i request including voltage

im going to try with CF disabled tomorrow, otherwise im just gonna sell the second 6950 and wait for a better single card from amd later in the 7xxx series

[tried something else, now card 2 will not clock but card 1 will, and without CF i cant get AB to work at all, clocks are set at 0/0 no matter what i do]
