May 10, 200620 yr Commercial Member i just bought a new dell, it has dual geforce 7800 gtx w/ slii'm not sure i know what that means yet ;-)anyway, there is a total of 4 dvi connectors on these two cards. i run two monitors (i did when i had my trusty ati card - don't get me started)i have one monitor plugged into the first and second port on the first card. is that right? windows works, all other apps work. all except flight simulator :-(no matter what i do. fs9 starts, splash screen appears, the primary monitor goes black (as if fs9 was going into full screen mode), and then everything goes back to windows. the fs9 process is not running.i've tried reducing the resolution. i've upgraded drivers (84.21) i think. i've removed the sli bridge between the two cards, i reinstalled xp sp2. everything but call dell.anyone see anything like this?i guess my next step is to remove one of the 7800 gtx cards.jd JD Read my blog
May 10, 200620 yr Hey Jd,Sorry i can only tell you what SLI is. SLI is simply just using 2 gfx cards for the workload of one only spliting it (i.e. Dual-Channel RAM) but getting increased performance.As for the monitor issue, i hope others can help you with your problem, im not using multi monitor setup
May 11, 200620 yr Hi JD,Fs2004 does not support SLI.For you that means that you can only use one card. FSX will probably support it. 5950x3d 5.4-5.7 GHz - Asus ROG 870 Crosshair Apex - GSkill Neo 2x 24 Gb 6000 mhz / cas 26 - MSI RTX 5090 Gaming Trio OC - 1x SSD M2 6000 2TB - 1x SSD M2 2800/1800 1Tb - Corsair 5400 case - Corsair 360 liquid cooling set - 3x 75’ TCL tv. 13600 6 cores @ 5.1 GHz / 8 cores @ 4.0 GHz (hypterthreading on) - Asus ROG Strix Gaming D - GSkill Trident 4x Gb 3200 MHz cas 15 - Asus TUF RTX 4080 16 Gb - 1x SSD M2 2800/1800 2TB - 2x Sata 600 SSD 500 Mb - Corsair D4000 Airflow case - NXT Krajen Z63 AIO liquide cooling - FOV : 200 degrees My flightsim vids : https://www.youtube.com/user/fswidesim/videos?shelf_id=0&sort=dd&view=0
May 11, 200620 yr Author Commercial Member so i have to remove one card? or is their a way to disable one card while running fs9? i don't think i have sli enabled on the nvidia properties screen.sorry for the newbie questionsjd JD Read my blog
May 11, 200620 yr Id say if your machine is soley for fs, and not really for other "heavy" games take one out and keep it safe for use FSX. Im saying this because of a statement made on the Toms hardware website."We did, however, detect a decline in performance with SLI in Flight Simulator 2004 as well versus a single card, despite the fact that FS2004 cannot run at all in SLI mode, or put another way: even if only one card of an SLI system is operating, performance falls below that of a computer with just a single graphics card installed. Not by much, but by a measurable amount."Article found here http://www.tomshardware.com/2004/11/23/nvidia/page30.html
