The card runs just 4 hours in continuous operation under Windows 7 Pro 64bit, the GPU case has a clock speed of 157 MHz and 300 MHz memory. Temperature is 35 ° C (room temperature 22 ° C) and the fan rotates at 40% according to display the automatic fan control. Manually lifted, he is slow for me to hear from approximately 50%. Even with 60%, I would still be able to enjoy games, desktop applications would be me then but too much. Manually lowered short time to 30% and 20%, I can not tell the difference just to the automatically controlled 40% - even my quieter PSU fan and sporadic disk accesses (Samsung!) Are louder. The card is now on the part volume so fully capable HTPC.
Clock speeds are adjustable via Catalyst Control Center between 600 MHz and 960 MHz for GPU (default 860 MHz) and between 1200 MHz and 1445 MHz for graphics memory (factory setting 1200MHz). After passing through the auto-configuration for maximum functional overclocking 5770 resulted for "my" a GPU clock of 950 MHz for memory clock of 1435 MHz. The auto-configuration was a long time until the final outcome has been determined, the fan power is automatically adjusted upward during the period from 40% to 50%, noise is negligible.
Windows 7 Experience Index 7.4 - by far the fastest component of my system. BattleForge, Dragon Age, Avatar (I played only on consoles years and my last was GameCube and PS2) run very smoothly with the card (processor of my PC is a fuel-efficient Athlon 5050e with 2.6GHz, Windows 7 Experience Index 5.7 ).
Since I had at several other ATI cards (4670, 4770 and 5750) problems in 2D, here equal to clear: The 5770 provides a completely quiet, stable and not disturbed by vertical stripes image in HD or even SD playback ( Blu-Ray, DVD), black is displayed evenly across the entire screen area. A bucking (flash, flicker, collapse) in 2D mode under Windows 7 is not available - will be delivered probably because the card innately slightly overclocked (the low memory overclocking some 57xx models 7 can cause-described error under Windows; because This is also found in some NVidia cards under Windows 7, you suspected the "error" in Aero from Win7 and hopes to remedy with the first service pack).
Found one voucher for Dirt2 there's also, the game needs to be downloaded via a "Steam account". Also supplied is a mandatory CrossFire connection (if my PC two slots, I could come straight into temptation ...) and also an additional adapter from DVI to VGA. Thus, the connection options extend next integrated DisplayPort, HDMI and DVI on 4. Driver CD and small sticker "Fueled by Sapphire" are also available.
Who not significantly higher performance of '58 or '59 series needed, but still very good graphics performance in comparison to older graphics cards comparable low power consumption and reference behavior in terms of ventilation / wishes volume, is the 5770 best served with the Vapor-X version of Sapphire.
