Yo i just bought a

^ but facilitates better overclocks.

Eg: HD2900 with both its 8pin and 6pin power-inputs routed to two independent +12v rails enhances OC's and somewhat does reduce artifacts when playing with the clock-speeds or simply stress testing it.

A chinese team used two 2900 cards connected to a modular PSU made by ABS Tagan. The 8pin connectors were connected to one rail and 6 pin to another. When they did this, they actually got better OC's. I'm hunting for the link ATM.

In context of Kursah, yes it won't quite help him.

Okay I'll put the the link soon...it's Chinese translated by Google....I actually used StumbleUpon toolbar to catch that link earlier.....will put up that link soon.

a better psu wont make your pc/graphics or anything else go faster

Ok, how come with my 7800 gtx 256 mb silverstone 650w psu and asus a8n32 sli deluxe i was getting better framerates at 1024x768 no aa max than with my winfast nf4 sk8aa 8800 gt with same psu silverstone 650w.

i want my goddamn asus/7800 gtx back and im gonna rma this pos 8800 gt and buy a new psu lol.

 

[bigmacks433]

mind you ive seen artifacts in 2 games with the 8800 GT i havent seen with the 7800 gtx using same psu.

 

[bigmacks433]

Here's a picture of a artifact in soldier of fortune payback all of the trees blink with black leaves instead of staying green normally.

See' the black leaves? they constantly flash black like that ut3 models flash black also kinda.

hard to capture how bad it really is might not look much but its rather damn annoying.

@W1z
okay I'll try and put up the link if I get it. meanwhile if you have a two spare HD2900 and a modular PSU where the PEG power connectors are routed to different rails (Eg: ABS Tagan BZ 1100 or Antec TPQ 1000), try doing this:

Normally a (1x 8pin + 1x 6pin) will be routed to one rail or two rails commonly when not combining the rails. You have two such combinations amounting to 2x (1x 8pin + 1x6pin) out of the 6x +12v rails. You just have to interchange them or connect them criss-crossed, I hope I'm clear. Of the one rail, one 8pin should go to one video-card, while the second 6pin to another, same with the second rail. Do this and perform a stress test with ATITool, you'll see lesser atrifacts, provided you are cooling the crossfire setup properly ....meaning that you can go further with the OC.

 

[bigmacks433]

waiting on 7800 gtx 256 mb replacement and asus a8n32 sli deluxe hopefully i get back working stuff what i sent in .

then i can do some more testing, but im gonna buy a new psu, but i have 3 psu's performance sucks with all 3.

one is silverstone psu 650w dual12v rail 18 amps

other is lonestar 550 single 12v 19 amp

colorits 500 single 15amp

so psus is problems? but still doesnt explain everything artifacts shouldnt be appearing even if its low powered .

owell im gonna send in the 8800 GT when i get my 7800 gtx back get new psu.

 

[bigmacks433]

the silverstone isnt lower than the 8800 GT spec though because it's a dual 12v each 18 amps with combined amperage of 36 more than the 28 nvidia recommends so is it really the psu? this shit freaking sucks is all i know even the bfgtech guy said it was sufficient.

the silverstone psu has got to be failing even though it seems to be working great wtf or it doesnt like dualrails but it seemed to work great with 7800 gtx even though it would sometimes get lower power bug that's normal just reboot goes away.

i want to test something out for you. can you get a screen shot of your cpu-z for me? I want to try something when i get home.

Heres cpuz shot

Sorry for so many post's but yea some of you may know im alittle pissed

everything i have is broken

http://img87.imageshack.us/img87/8909/hjhjgws6.jpg

Im buying a new psu and if that doesnt fix it then rmaing this damn 8800 gt.

but i cant wait to get my a8n32/7800 back.

 

[Cold Storm]

we've all been down that road. i'll do my test once i dont have to use a touch screen to do everything. just last week i wanted to blow up my new rig. lol

 

[bigmacks433]

scanned for artifacts with atitool didnt find any.

for a few mins.

damn i really dont want to spend 120+ dollars for a psu though but i guess im gonna have too even though this psu should be fine and seemed to work great with everything untill i got the 8800 gt and one day i turned off other pc and never turned back on . this psu is haunted stop using this probley the one killed my stuff.

still artifacts in game with all 3 psu though*

 

[Mussels]

what drivers are you running? i've heard of black textures blinking in UT3 that are fixed by the latest beta drivers.

I've got to admit somethings up, if ATI tool doesnt cause the same problem. ATI tool should make yoru video card go at 100%, and use the same amount of power as a game would.

Could you try running 3dmark 06 for us? Its the only thing i can think of thats free and stressful on a video card, and may give us yet another clue.

 

[bigmacks433]

Maybe it's not even powersupply related? because 1024x768 no aa in ut3 max the framerate is the exact same with 650 silverstone psu which is supposiblt sufficent as the underspec 550 watt 19 amp on single 12v rail psu.

could it be the card's just screwed up? because it is afterall artifacting.

i cannot wait to get my damn 7800 gtx back to see if the framerate is indeed better using that and will know for a fact 8800 gt is screwed lol.

becuase i have a feeling my silverstone psu is sufficient and is in working/good form and the card's just fubared.

 

[bigmacks433]

really wish i had another high amp single rail psu to test though, i just will feel like a idiot when it doesnt fix artifacting or fps issues.

 

[bigmacks433]

i tried to run 3dmark05 but i couldnt submit the damn score for some reason.

gonna try 3dmark06 my score will be lower than most people with 8800 gt because im not running dualcore and 06 depends more on cpu than 05 does.

 

[bigmacks433]

http://nzone.com/object/nzone_ut3_downloads.html

i actually downloaded and tried the drivers nvidia recommends and i still seen artifacts on models.

 

[bigmacks433]

i have a feeling it's the card itself because i dont remember artifacts in ut3 with 7800 gtx.

 

[bigmacks433]

about to run 3mark06 and post score aswell* 68% downloaded.

 

[phanbuey]

dude... youre a bit too excited about this haha... your 7800GTX is NOT better than your 8800GT, UT3 has known issues with the drivers, fixed in the lates release (as was said b4)... your PSU is fine. Your 3dmark score is gonna be handicapped by the rest of your system. And still 8800 is gonna double the 3dmark06 score or your GTX.

if your gonna send the card back in you should maybe consider at least a 3850 or 3870 - then you wont have to worry about PSU as they use less power.

EDIT: the drivers you need are the betas... are those the ones you dl'd?

6549


that's what i scored in 3dmark06.

i scored 4000 in 3dmark06 with the 7800 gtx.

shouldnt it be higher?

ok, so what is your framerate in ut3 with 5 bots 1024x768 max no aa?
on the dm map arsenal


mine is 30-40 fps 8800 gt.

i remember 50-60 fps using 7800 gtx

Hold on lemme dl the game and ill post... EDIT: just saw u said no AA.... you should be getting more than 30 - 40 FPS at 1600x1200 with AF and AA (link). - so its definitely weird you getting such low FPS, especially only in one game. What is your 3dM06 score?

can you run the deathmatch map named arsenal if you own the full game?

i get 30-40 fps on that map with 50 bots 1024x768 no aa max and i was getting higher on 7800 gtx same psu same cpu same map.

plus black/artifacts in soldier of fortune payback and ut3, i guess the card is bad and psu.

i do not remember the game artifacts wih my 7800 gtx.


I SCORED 6549 3dmark06.

 

[{JNT}Raptor]

does anyone have ut3 and a 8800 GT performing good? lol

Since you so easily disregarded my original post.....obviously you as well overlooked my statement of running UT3 on my rig.....go read It.

Get a 5000+ black edition CPU and the 650 PCP&Cooling PSU....then you can quit your bitchin.

i scored 11,777 in 3dmark05.

i didnt see your post man, so you are running ut3 1024x768 no aa max with 5 bots on the deathmatch map named arsenal hitting solid 60 fps? im running 30-40 fps.

dude the psu might not even be the goddamn problem you arent seeing artifacts in ut3 like me are you? plus the bfgtech guy said my psu is fine.
