hi guys,
recently upgraded my ASUS 512Mb HD4850 to a MSI cyclone 1Gb 6850 (core 775Mhz, memory 1000Mhz)
im using a 'cheap' 700W PSU (cables not sleeved etc)
was getting some flickering in the monitor upon install..........ran some msi kompressor benchmarks doing some overclocking in the process (850Mhz core, 1200Mhz memory) all was good.
turned off pc to disconnect 1 hard drive and 1 disk drive to free up some extra PSU power
flickering disappeared upon reboot
started to play Black ops - cranked all the settings up to MAX max (one i set to extra lol) and after a few games i started getting issues, occasional freezes - 2 minutes later blue screen crash........
Uable to get PC to reboot so changed back to old 4850............. note new 6850 didnt feel hot at all
after reinstall of old card, pc booted fine.............
What do we think gents, my gut (along with previous knowledge given to me prior to upgrading) im thinking that my 700W Power supply isnt up to the job of this 500W gpu - 2 x HD, 2 x DB, MoBo, 3 x fans, etc........
????? thanks
