HD4870 bios modification / powerplay

post #1 of 2
Thread Starter 
Hello

my card kept changing from 500mhz to 750mhz clock every few seconds even when my comp was completely idle.. anyway I saved my bios, modded it and flashed it to run at 760/900 all the time, idle temp went up from about 34c to 36c, and it's only 45c under load (water cooling)

is it safe to keep it like this?

thanks

Those temps are good. just make sure your memory and vrms have adequate cooling. my 4870 had powerplay and idled hotter than that, even with a third party cooler. As for powerplay being off, im not sure but i cant see it doing much harm, people run their cpus without speedstep and dont have trouble. Run some artifact testers, and if nothing shows up your good.
