As the titles says, i got a new CPU to play with in my media PC. The results may help you choose between an Athlon II x2 or x3, depending how it all turns out. Will be editing as i go along, please re-check the first post every now and then. One thing you may ponder about: i'm not concerned with load temps or power usage, since this is a media PC. its hardly ever going to load, so this test is focused on power usage at idle. Its also kinda obvious that a triple/quad core is gunna use more power than a dual. System setup: Motherboard: GA MA785GPM-UD2H Onboard radeon 4200IGP - 128MB Sideport ram + 256MB system ram 6GB DDR 800 CL5, 1.8V Old CPU: Athlon II x2 240 2.8GHz Stock:1.35v Undervolted: 1.1v (24 hour stable linpack, OCCT, etc. Never a single crash in 24/7 use for 3 months) Coretemp idle: 23C New CPU: Athlon II x3 435 2.9Ghz ADX435WFK32GI CADAC AD 0945EPFW Stock Voltage: 1.40v Undervolted: 1.15v in testing 4 cores enabled: So far, with 4 cores enabled it 'unlocks' to a phenom II x4 B35. However its not stable at stock clocks. Am testing various combinations to see what it'll boot with.
