post #2091 of 6939
FYI , ur mobo shld be able to run a 4x CFX setup..

"The dominant feature of the Asus M4A79T Deluxe must surely be the quad PCI Express graphics slots (2x16, 1x16 and 2x8 or 4x8) which allow you to combine your Socket AM3 Phenom II with as many as four ATi Radeon graphics cards."

my mobo has the same setup but its useless with 6800 series.other than multi monitors.iv tried useing my 260 for physx but the physx mod causes system instability and kills my overclock.and the 6800 series only supports x2 cfx.but I can confirm no performance loss from x16 to x8 lanes.

Somewhere (gOoOGLe) and I'v quite frankly forgotten where ,,, they compared a whole bunch of CFX configs-- 16x and 16x ... right down to 4x and 4x--- guess what,,, the whole setup resulted in a delta of a couple of FPS at worse :_) and they put it off to the margin of error..
saturating an 8x lane is no joke, and I doubt it's gonna happen before we see 12-core i9s from intel --- heck , I'm planning a 6870 in the 16x and ma current 6850 in 4x CFX when I get the cash -- prolly June -July

Btw, smoke420.. duude... stay away from the psyx hack :_| or simply get an aegia card like me :_) got it from a friend and it trips the CPU score in benches xD,, that psyx hak is pretty sad.. plausible but not worth the heartburn.. and I believe nvidia is working with game studios (AS ALWAYS) , now to disable psyx rendering through this hack.

The way I see it, physics is now moving to CPUs and opencl and all... keep faith !

@WIGILOCO Lol, Asus :@ I have less to say.. I like their hardware.. but then again , why couldn't they implement a 2x 16x lane setup for ur mobo :I beyond me.

Great score, your bench is at 1920x1080 though while his was at 1680x1050. How did you achieve such a high OC?? whats the voltage? is it stable? if so at what fan speeds?

Sorry I'm just real curious because I plan to purchase another ASUS EAH6850 soon for crossfire, thanks.
the overclock is high but so is the voltage 1.337 stock cooling (changed tim and mounted fan higher).not stable but dont care these clocks are strictly for benchmarks.there is no game out that needs anyware near that.
the highest I benched so far 1030/1200 v1.337
game 940\\1120 v1.25 (metro 2033 none of my other games require overclocking)
highest stable 980/1140 v1.3
im using a custom fan profile in afterburner.gpu temps never past 68/72c..
the vreg temps is the problem with this card I have a 20c difference from card to card 68/88c

does it still work? I got x3 my cpu scores in vantage but no difference in 3d mark 11 and the games that support physx no visable difference.not going to buy a card for physx was just hoping to use my gtx260.

YOU:: "but no difference in 3d mark 11 "

ME:: " nvidia is working with game studios (AS ALWAYS) , now to disable psyx rendering through this hack."

I'm all pleased w/ maself rite now =...)

Hey , a 260 !!! SELL IT sell it as a crysis killer =D hehh.. get some cash.. put more together ... go CFX !!!
post #2098 of 6939
OH IM SO STUPID :@ u'v already gone 2-way :/ didnt c that before!

Well well.. again , sell it off.... and ..
Lets see... its not COMPULSORY to have an SLI conn. cable ??? Right?? so in theory, shldn't a 3rd card just work, albeit w/ some extra strain on the Pci-e lane ?? just a thought.. Cause then u'd have the fastest amd rig around <1000$ ?? Oh and then the processor///

so see-- a better investment must be holding off till amd launches their 32 nm range.. and that alone will get u better FPS ??? Not that u'd need it I'm sure :_)

OR SSD , go SSD !! that'll raise ur min FPS ---- that's what they say... no more stuttering (hdd lag)

Only really helps for badly designed games or if you don't have enough RAM.
