Why is it people still don't get it. Cards no longer sync clocks any more since the 177 days when it comes to sli. The clocks are defined in the bios and the card continues to run in those clocks in single, dual, tri, as well quad sli. Tells them of first generation sli being able to sli up to 32 gpus they go bull sh^t then takes out a $400 alchemy board that has 8 VSA-100s on it.
You need to test each card in single configuration to rule out one being an issue. Second while you are at it tell us about your psu since any thing can have that wattage hell I got light bulbs with that rating also got a 700w DC to AC inverter that runs off 12v batteries.
okay ive tried a different sound card but this one was like 16 bit and my games require like 32-64 bit sound. So the sound was crackling and was of poor quality
Maybe the two cards are taking to much power away from my motherboard. My motherboard is trying to compensate for the sound but it just isnt working and thats why i am getting such a crumby sound duing my 3D intensive games.
Would it be a good idea to buy a sound card? If so, what sound card should i buy?
Is there someway to set the power usage of my sli 9800 gt 's so that my sound wont be crumby during the most instense 3d graphics?
Well you did complain of having coil squeal with you psu's. As for sound either RMA the board or go look for a Audigy sound card since they have their own filtering stages and processing. Also check the cable leading from your system to your speakers you have have a grounding issue. What model is your cpu?
Do you have any warranty of return value on your PSUs as well as your board? Since you got an obvious electrical issue with either the board or the psu perhaps both. First try to really rule out the psu making the coil squeal and not some other component. Here is one other suggestion open a ticket with XFX and ask them questions regarding the audio issue it may be grounding.
the same problem occurs with both power supplies (i have tried an ultra 500 watt psu and also a 1100 watt psu), It never happens when listening to music or playing video and never happens on one card or the other (separately or one by itself)
and it ONLY happens when i am in the middle of intense 3d gaming
