hi everyone , as u can see im new here and my English isnt perfect ,
i have a HD 5770 and i used to overclock it to 960Mhz core and 1430Mhz memory until today ! from today morning i cant overclock this thing more than 880core and 1330memory , i know what u wanna say but im somehow sure its not my PSU , why ? because i overclocked my Phenom II 955BE to 4.0Ghz (always on stock and 1.2Vcore) and Vcore of 1.48 and u know its huge amount of wattage i've drained from my PSU but it worked completly stable , plz someone give me an idea , its driving me nuts cuz i afraid my 5770 is near the end and i havent changed a single piece of hardware or my OS .
my system spec : Phenom II X4 955BE - 6GB 1333 Geil - saphire HD 5770 - 480W Green PSU (im living in Iran and Green PSU is OCZ PSU acctualy and its a very good PSU here with 5 years warranty !) Asus M4A77TD Mobo , Windows 7 ultimate 64-bit , and its about 1 month only that i have this rig , tanx for ur helps and ideas .
i dont think its dying out ! i never overclocked it , just 1 full day only to play damn Metro 2033 , that 1 day i overclocked it i used all the same hardware and software im using right now ! this is the most weird thing i ever had with PC , that's why i always choose console over damn expensive and useless PC but plz someone help me here to find out about this !!!
damn ! a weird problem and a more weird way to fix it ! i reconnected the 6-pin power connector and now it works right on thoese freq's again !!! why was that realy ?!
spentshells i think ure right and now i read more i see 1430 for memory is high , now its 960 and 1380 but anyway it was stable on 1430 with furmark !
