Hello everyone.I bought a Sapphire ATI HD5770 1gb gddr5 . My Current cofig is C2D E8400 3.0GHz, 2GB ddr2 ram, Intel DG31PR Motherboard and Thermaltake TR2 500W Power supply and samsung T200 20inch monitor. After installing the card, I noticed 2 problems. There’s a slight lag/sudden drop in fps while playing some games, very slight lag but its noticable. Specially some old games like NFS mostwanted, TDU, css, and GTA4 EFLC the lag is too high. On the other hand, in some new games like, Split second, blur, Mafia 2, Splinter Cell conviction, Grid(though this one is old) its barely noticable. I tried doing the following things>
1. Updated the Ati CCC to the latest one
2. Re-Installed Windows 7
3. Tried with different settings of catalyst A.I
4. Different video/graphics settings
But still problem is there. Need help!!
Another problem is, my card’s default core clock is 850MHz and Memory clock is 1200MHz, yesterday I checked with both GPUz and MSI after burner , when playing games memory clock goes up to 1200mhz but, Core Clock is MAX 500MHz only, never goes more than this!! At Idle core clock is 157mhz and memory clock 300mhz. and core clock/memory clock fluctuates between idle and maximum while playing games, which is really weird. I tried to change the core clock to 852Mhz from msi afterburner, but the clock changed to 600Mhz only in games. Noticed Same problem in each and every game. I didn’t notice any other problem. Card's idle temp is 46-51 degree and 56-61degree when at load. Please let me know if this is an issue with the card or some other settings? And I need to know the exact reason so that i can claim my warranty. thanks
