HIS ATI Radeon HD 5770 on Win 7 ^$bit driver issues....

OK Just built me a new sys :
Microsoft Windows 7 Home Premium 64-bit
Intel Core i5-750 Lynnfield 2.66GHz LGA 1156 95W Quad-Core Processor
GIGABYTE GA-P55-UD4P LGA 1156 Intel P55 ATX Intel Motherboard
HIS H577FN1GD ATI Radeon HD 5770 1GB 128-bit GDDR5 PCI Express 2.0 x16 HDCP Ready CrossFireX Support Video Card
CORSAIR CMPSU-750TX 750W ATX12V / EPS12V SLI Ready CrossFire Ready 80 PLUS Certified Active PFC Compatible with Core i7 Power Supply
OCZ Obsidian Series 6GB (3 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800)
Thermaltake Silent 1156 CLP0552 92mm CPU Cooler For Intel Socket LGA1156

My issue is that my video card drivers are not working right I have tried old and new and still locking up the card when I play Dirt 2 or NFS Pro Street. Everything work great until I put a load on the video card like try to play a game or go full screen with online video (u-tube – CNN new) Yes I tried the 9.12 also nothing well fix it. I have removed all drivers first and all ATI Catalyst, too. I have installed the ATI Radeon HD 5770 on to my old XP Pro 32 bit with 9.12 XP drivers and it works great and can over clock the H out of it.
But Win 7 64 bit with no over clocking at all well not work worth a ^%$. Anyone have this issue? Did ya fix it? I am about to reload XP Pro 32 bit but would hate to do that.

Microsoft Windows 7 Home Premium 64-bit

From read way to many other posts the best thing for me to do is return it for a replacement of the same card and if it stills happen then return it for anything that is not from ATI/AMD or just want for god know how long for someone to come up with a fix. This has been going on in the post for over 6 mos. now!!!!!!

What not one of you can find a driver that can make this 5770 work? No help? No cule?
I am looking for someone that has this prob and how they fixed it. Not hoe they reture for a different one. And if you have a rig like mine how did you get yours to work under a load?

8 months and still no drivers for Win 7 -64 and 5770.

Use MSI Afterburner & Underclock the memory as low as you can. Then it is solved. Now it is a matter upto you, increase the memory in steps and test if the card becomes stable at that speed.

For my gigabyte hd 5770, I flashed it with asus bios, then used asus smartdoctor to lower the memory clock to 955MHz (3820 MHz effective). Solved the problem.
