The Official Opteron 939 Overclocking Thread

[dinos22]

Something tht concerned me though is tht even though the CPU primed upto 3hrs, he didnt stop it but it rebooted his CPU! I find this very strange behavoir, usually prime should just fail, a reboot tell me tht he may have spikes on his CPU voltage. A rock stable CPU voltage line is a must for pushing these babies

i wouldn't be concerned about that...i had a couple of Week 17 EPMW Venice CPUs and week 16 GPAW CPU......week 17 CPUs would stop with an error in Prime or SuperPI or OCCT.........week 16 on the other hand would just reboot or hardlock....strange CPUs.........week 16 was 32M SuperPI stable at 2.9GHz....if I went 1MHz higher in HTT.....reboot...hehehe with Wk17 CPUs they were stable up to 2850/2875 in 32M if i tried Spi even at 2950 on them it would just error but not crash/reboot......also I needed less Vcore with Week16 for SPI/more for 3D but I needed more vcore with Week17s for SPI/less for 3D
