4870x2 troubles

Well the title of the topic says it all. My 4870x2 has some serious problems with drivers... I tried installing catalyst 9.4 and the display driver. I have the beta windows 7 64bit. The problem first started when i noticed that only 1 core of my gfx card was working. I had windows vista 64bit at that time. i updated to windows 7 and the vista drivers were removed and basic microsoft drivers were used instead. The microsoft drivers used both cores of the card but the performance was much weaker than i was used to. Then i tired installing ATI 9.4 display driver. That made the performance worse than the basic microsoft driver. both cores were working at 30% max. Has anyone heard of this problem or seen it before? The last time i had this problem I had to reinstall vista and reinstall all the drivers. I would do that but every time i do, i lose another DRM activation.... I hate DRM activations soooo much.... I've already lost the use of Stalker clear sky, and I'm on my last activation of Far Cry 2. Thanks for checking this out and i dont think i am the only person to have this problem but i have not seen it around. Please help me!! oh and one more thing, my card has never ran at the default speeds only ran at 500mhz core and 500mhz memory. I used rivatuner to fix this and set speed manually. I dont know if this is has anything to do with the problem but just another problem with my card.

don worry, it is in power saving mode,
it will run at full clock speed in game.

Anyone think that the OP is just 11yo? BTW hardware drivers must be installed for each OS if the system is dual boot.

Well it looks like im going to have to fix my problem the old fashioned way and reinstall windows.
