Crossfire messed on WinXP ??

[eva2000]

With E6600 + Intel D975XBX badaxe rev304, I decided to try crossfire with master in x16 slot and slave in x4 slot for now, but seems whenever i either install .net framework v1.1 or 2.0 and cat 6.6 it foobars my OS with missing newdev.dll , apps when clicked won't load and missing app associations, slow movement in windows etc ??? and forces me to have to restore my os partition from a back up ??

everything is fine upto .net framework install.. after catalyst install 6.5 or 6.6 it goes to crap :(

E6600 Step 5
Intel D975XBX Badaxe rev304 no mods
512MB HIS X1900 Crossfire
512MB Gecube X1900XTX
2x512MB Corsair PC5400ULv1.5
700W OCZ GameXstream

any ideas ?

You got largesystemcache enabled? If so disable it. Try disabling write combining as well.

[eva2000]

Thanks for the reply

Yes largesystemcache is enabled....

will try with it disabled

ditto on write combing...MUST be disabled before you enable CF. if not it causes all sorts of problems with disk read/write access...really weird.

ah ha! so that's why windows throws up file structure corruption on drive E at system boot!!! (drive E has no files on it in the first place lol) tried it 4 times each time restoring a working image of my os partition and reinstalling drivers hehe

just tried with only 1 card in system and dotnet v2.0 and cat 6.5 installed fine...so ..disable write combining

will try this tomorrow.. of to bed now :)

thanks again!



oh here's a pic of what mean by needing to use x4 PCI-E slot temporarily until i get my 2nd GPU waterblock

Looks awesome. Poor CF card is feeling left out of the loop :(

[eva2000]

yeah

hmmm same happened again even with write combining disabled

restored ghost image to before drivers installed
With only master card in single card installed drivers
then went to properties to disable write combining
installed 6.5 official cats
rebooted
installed slave card with dongle
booted into windows fine no probs
launched CCC see no crossfire tab
so reboot
now same slow apps and stuff... didn't check to see if write combining was reset to ON by CCC ?

does catalyst driver re-enable write combining ?

okay even swapping the slave card back to stock hsf air and putting the card in 2nd PCI-E slot x8 one and the master card in 1st PCI-E slot x16 even without the dongle will result in filesystem corruption, BUT only after installing the catalyst drivers (6.5 or 6.6 official). It's doesn't have file system corruption when catalysts arent installed.

This happens with or without write combining enabled weird! :(

I hope NOT to have "DisablePagingExecutive = 1" and "LargeSystemCache = 1"......IF YES, then make them = 0 ......;)

Use the "LargeSystemCache = 1" ONLY when you bench Super-Pi and then disable it again(= 0 )......;)

write combining = Enable.....

[freecableguy]

Try this.

yeah

REBOOT

[eva2000]

thanks FCG, tried that same result though = filesystem corruption

Use the "LargeSystemCache = 1" ONLY when you bench Super-Pi and then disable it again(= 0 )......;)

write combining = Enable.....
hmmm i had those 2 registry settings enabled as i slipstreamed WinXP SP2 with custom registry settings to load those by default as enabled

Guess i need to make a new custom slipstreamed winxp sp2 cd for crossfire rigs heh

[freecableguy]

nothing conflicts with DisablePagingExecutive = 1 (this just tells Windows not to page to disk (VM) key core libraries). LargeSystemCache = 1 is the same as setting system optimization for services vice programs. this has been known to cause problems with SLI and CF. make sure this is 0 and write combining is disabled. then reboot. then load CF drivers. reboot. enable crossfire. should be working then.

[eva2000]

Thanks redoing a new custom slipstreamed winxp sp2 right now without the registry tweaks heh.. hopefully this fixes things

anyone know the custom registry tweak to disable write combining by default ? :)

hmm think i found it

Add the following key in the registry:

HKLM\SYSTEM\CurrentControlSet\Control\GraphicsDriv ers\DisableUSWC

Note that a value is not required for this key

So in *.reg file add


[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\GraphicsDrivers\DisableUSWC]

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Session Manager\Memory Management]
"DisablePagingExecutive"=dword:00000001
"LargeSystemCache"=dword:00000000

[freecableguy]

looks like that should work

[Gautam]

Hope you get it working. On the AOpen i975X with a Yonah, I needed both LargeSystemCache and Write Combining disabled. But, for some reason, CF works flawlessly with both enabled on the Asus P5W DH. So it might be board-specific. I used to disable Write Combining in safe mode after installing the cats. IIRC installing the drivers would enable Write Combining by default.

[ugp]

Man all kinds of CrossFire issues with you lol

That would be my kind of luck right there.

[eva2000]

Finally got crossfire to work !

Thanks guys for all the help :toast:

oh one more question in ati tool

bus1 and bus2 device ids are they master and slave respectively ?

[eva2000]

nothing conflicts with DisablePagingExecutive = 1 (this just tells Windows not to page to disk (VM) key core libraries).

hey Kris how are you alternating between 3dmark and pi runs for disabling and enabling largesystemcache setting ?

disable largesystemcache for crossfire

then for pi, disable crossfire via CCC, shutdown pc and remove slave x1900xtx card and reboot pc to enable largesystemcache ?

then disable it again, shutdown pc, install slave card and reboot back for 3dmark ?
