Crossfire in 3Dmark05/06

[LanceCrossfire]

first my spec...

Intel Pentium D 805 [email protected]
1024mb OCZ PC5400 667mhz(single channel)
Intel 975XBX "bad axe" rev304 motherboard (20/6/2006 bios installed)
1x Connect 3D 512mb X1900 Crossfire Edition
1x Gigabyte 512mb X1900XT-X
1x Jeantech 600w Artic PSU (powering mobo & gigabyte card)
1x Hiper 580W PSU (powering Connect 3D card & drives)
250Gb SataII HDD
NEC DVD-RW
Windows Media Centre 2005

i have the latest drivers for the cards(catalyst 6.6), updated the bios etc..., crossfire is enabled, tried reversing the cards, swapping dvi sockets, and tested them individually, everythings ok but im still only achieving roughly...
3Dmark 05 = 8900-9500
3Dmark 06 = 7000-7500

sureley i should be getting better?! thanks for any help in advance.

what res are you at? and do you run all the tests or just the default ones?

 

[LanceCrossfire]

just ran 3dmark 05 with all tests selected at a resoltuion of 1024x768 and scored a poor 9407 marks what do people reccommend i do i didnt pay £550+ on 2 cards to get single card scores do you reckon single channel memory could be holding me back? i know it would alittle but no 4000 marks worth:S
does 3dmark also detect dual cards?

 

[LanceCrossfire]

yeah i have the crossfire option and its enabled, just installed the omega drivers after using driver clean to get rid of the catalyst 6.6(does the omega even have crossfire support?) anyway i got a slightly lower score, leading me to assume only one card is running... theres no option in the bios that i can see... if anyone has the rev 304 of the bad axe could you please confirm.

 

[LanceCrossfire]

think im gonna reload and start from scratch and see if its software related... they may be some driver debris from my last mobo and chipset...

 

[LanceCrossfire]

ran the lost coast video stress test and a still get a very similar average of about 55fsp @ 1400x900

 

[LanceCrossfire]

i tried the omegas just to humour myself, they dont come with CCC(its a modified version without Xfire support), the machine is being formatted and reinstalled as i write this... hope its sorted

 

[LanceCrossfire]

just reinstalled windows and all the drivers and im now getting 10000marks on 3dmark 05 which is still very low...

 

[LanceCrossfire]

tried both cards individually and they work fine, this is doing my head in!!!

 

[LanceCrossfire]

would having 3dmark 05 build 1.1.0 instead of 1.2.0 really effect the score on my hardware? dont know which version ive got so i'll check when i get home...

does everyone think my 3dmark 06 score is ok(havent ran it since reinstall, so should be a few hundred better)?

 

[LanceCrossfire]

this is a screen dump of what 3dmark 05 reads in my pci slots, as you can see it says the second slot(x8) is available

but in 3dmark 06 it registers fine thats why my score is spot on...

i disabled crossfire and ran both the tests again, came out with nearly the same score in 05 but a lot less in 06... so my question now is why isnt my slave card registering in 05??? ive reinstalled windows, drivers the application, updated bios, chipset drivers etc... and still no luck... another thing ive noticed aswell in the bios is that my PSU readings seem abit off(my 600W PSU that is, remember im using 2)

V12 = 12.062
V5 = 5.084
V3.3 = 3.268
V1.5 = 1.464
Vcore = 1.218

that seem abit off??? anyway why is one app working in crossfire and not the other someone please help
