ATI 4850/4870 voltmod thread

[LuxZg]

Just a bit of info about power requirements and so on. I've asked Steve on legionhardware.com to check power consumtion of OCed system if possible, and he gave some extra info over here.

System is Q6600 @ 3.0 GHz with HD4870+Accelero S1. Rest of system is pretty normal (500GB disk, 2GB memory, X48 chipset). Stock temps are 74 idle, 82 load (stock clock/cooler) under Crysis.
Power consumption was 193W/295W and on 830MHz core/1150MHz memory (with S1) it got up to only 202W/303W (idle/load). You can see more data (temps, consumption, 790/1100MHz OC which is top with CCC, etc) in third post.
830/1150 was max oc with this setup.

Since you people say rising voltage on 4850 would result in much higher power (400+W) on around same OC (800+ MHz) I guess paying extra $$ for 4870 is better than paying extra for 4850+new PSU and than still having to bother with voltmoding and the rest.

And 303W total power should be more than acceptable to my 450W PSU even if it had lousy 75% efficiency. And I still have just dualcore vs quad (which is used in review)

Thanks for advices everyone, and I hope this info will help others as well!
