provide 40a on the 12v line
is it much better ?

More power is obviously better. I saw that 18x4 psu too and it looked good, but when I checked Nvidia's site, the 17a + 18a should be ok for GT cards. If you are doing 2x GTX cards the list of approved PSU's is smaller.
Im doing 2x GT cards and my PSU is listed on their site as having ample power to drive my cards so I am inclined to believe that its not a power problem I am having.
I did find it interesting that w/o the bridge your 3dmark finished. Are you certain it was running in SLI mode? 34k seems kinda low for your system with 2 GTX cards... or GT for that matter. My system will do 38k with one GT card clocked at 550/775 and an E6400 @ 2.66. Im thinking that sli for my system should be 45-55k...
Hey, I want to thank Big_Sam(for introducing the SLI driver) and BarboneNet(for rehosting the SLI driver). I'm now able to run Oblivion at the highest quality without the graphics stuttering all over the place. :D
Hopefully, nVidia will release the official ones soon, but this one is better than what I expected and will definitely do the trick until that time.
System specs:
Intel d975xbx
P4@3ghz(soon to be replaced by the e6600)
2xEVGA 7900 GT KOs in SLI
2x1gb G.Skill@667mhz
2x250gb WD SataII in Raid0
X-Fi Fatal1ty
Sony DVD+/-DL 16x
Antec NeoHE 550w
Seol
Glad you got yours working - Im looking forward to getting home tonight and seeing if I cant make mine work too.
What MB are you running?

First I'd like to thank Big Sam for this driver. I have it installed & its working perfectly. My 3DMark06 scores are around the same as my previous system, but I do understand that benchmarking will not be a strong point for a modified driver. All I want is good fps in games for now, and thats what I'm getting.
noobzed,
I had same problem using the asus flex bridge. Try flipping it, solved the problem for me:D
Anyone try these on an ASUS P5B Deluxe yet?
The MB is an Intel d975xbx rev.304.Quote:

Well I got mine running...
I flipped the flexible sli bridge (asus) - it might have just not been seated properly...
3dmarks went up by about 65-70% on all benchmarks.
03 is now 30k+ (without the cpu o/c)
05 is now 14k+ (with the cpu o/c)
06 is now 9k+ (with the cpu o/c)
I did have to change the coolbits dword to 1a to get the sli features with card o/c.
Iwas able to run all benchmarks and play COD2 for 2hrs straight without a single hiccup. (100+fps avg never less than 82 fps in smokey battles!)
Thanks big sam!

i do some test with underclocking but same issue, black screen in 3d01
e6600 at 1,8 ghz fsb 200 x9 , 1 stick of 1go ddr ram
underclocked 7900 gtx at 500/500
a fan blowing to the cards, all things unpluged ( like hdd, dvdrw )
in order to minimize the power wattage
but i encounter the same problem ....

what are your psu ?
coolbits dword ? what is this ? could help my issue ?
i have gun 2 x 7900gtx in a desktop case ov a 530 w psu on bad axe no problems.
hvat psu do you use
i use an antec phantom 500w , i unplugged everything not needed, all settings to default from bios to a fresh xp instal with the 84.66 moded
the bridge is connected too...
is there an order to plug the sli system ?
i mean first plug the card into slot 1 and after slot 2 and after bridge ...
seems to work now
10536 at 3d06 with 3,6 ghz e6600 and 2x7900 gtx stock volt and spd
no optimisation of bios or what so ever
56689 3d01, finally did
the 85.96 is superior to the 84.66 in terms of performances and stability ?
i can seem to get my sli working for some reason . i have 7900gt co and 7900 gt on a aopen i975x a-ydg . i can't seem to find my sli settings in dis propertys any ideas . thanks
It can't be if you use the modified driver. SLi control panel is in any case, even I have it on old P4P800 with AGP. :DQuote:

How long until we see some 9X.XX drivers?

I think that this question better to set for NV :DQuote:

I did a calc on my system - only 1hdd, 1rom drive, 2 sticks of mem, and 2 case fans. Peak usage could be as high as 471w according to this calculator. Given that I have a 550w psu I feel ok, but if I had GTX cards I would expect I need more power.
Now that being said - anyone have an idea why my 3dmark 01 is so low? I am getting about 38k - up only about 10% from my single card score. 03, 05, and -6 all went up by 70% but 01 didnt hardly move...
Another question for the group. What are "safe" core speeds for the 79XX gpu's? I have seen 65c under heavy load. This seems high for a cpu but I dont know if gpu's run hotter. Do I need to put a different cooler on my machine?

i have my sli bridge on with no luck still . must be something i am doing wrong . as anyone else heard of someone running these drivers on my mobo? here's a pic i have tryed everything i can thing of . the little lock think on the sli bridge goes down right ? i have tryed both ways , any more ideas anyone thanks.

It seems to me that you have the usual not modified driver.Quote:

i uninstalled the drivers in the control panel and rebooted and installed the modified drive . should i go into safe mode and delete them that way ? it's been along time sense i have done it that way , for get how somewhat .

This driver works for all without problems on any chipsets. You can see many threads about it in this forum.
