New Radeon 4850 - Not detecting my TV
http://forums.overclockers.co.uk/showthread.php?t=17957583
What motherboard, cpu and ram have you got? What is the make and model number of the psu?
Sorry for sounding somewhat patronising, but have you plugged in both power cables into the back of the card?
Rivatuner does do this indeedYou can enable Overdrive without overclocking the card, but Im going to assume that you are already doing this. Thats quite a hefty system you got there though, and depending on the integrity of the rails of that psu it may not be enough.
E.D.I.T.: How many hard drives have you got going? Any other devices that may be sucking the life out of the psu?
Im confused as to which card you have, as this threads about a 4870 your tired off, yet your other threads about a 4850.
Either way the GTX 260 is a cracking card, it would be more like a sidestep from your 4870, and it would be an upgrade if you have a 4850.
Anyway, my PSU is a Thermaltake TR2-550 PP, ATX 12V 2.0
/thread.
I would wager a significant amount of pretend money that this is the problem.
Out of curiousity, what card did you upgrade from? Chances are this PSU is not providing the appropriate juice... changing to a 260 probably wouldn't fix your issues. Other than the ATI control panel thing.
Ah now you are delving into the mind of a paranoid maniac!
I've been having lots of problems with my old computer and couldn't figure out what it was. All started when I updated my RAM to 4gb which made things worse. So I thought it must be my Motherboard.... then my Graphics card died on Christmas Eve
My luck has been so poor recently I'm automatically assuming everything is worst case scenario!
Anyway, my PSU is a Thermaltake TR2-550 PP, ATX 12V 2.0
I have a Audigy 2 ZS Soundcard and 2 Hard 250GB hard drives running seperately (not RAID)
Edit: by the way, when enabled, and after "auto detecting", Overdrive sets my GPU Clock at: 780MHz, Memory Clock: 950Mhz - what would be a non-over clocked setting?
Also, I had set my fan on a constant speed of 40% as it never ever seems to go near that even while running Crysis. That is where my problems started.
