So I recently began my journey into overclocking. I have a 955BE in a M4-79XTDEvo and 4G Gskill Ripjaw 1600. I have a Noctua NHU12P-SE2 cooler in Antec 900 Case. The reason I posted in the PSU section will follow shortly. Right now my specs are as follows:
FSB: 243mhz
CPU: 3645mhz
VCore: 1.4125
NB: 2637mhz
NB Volt: 1.2
HT: 2187mhz
GSKill Ripjaw 1600 Ram @ 1620mhz
XFX 6850 @ 875/1145mhz
PSU: Antec Basic 550W (I think that was the name)
I can run prime95 for 2hrs with no problem but temps get up to about 58C (41C at idle), my room temp is 27C@51% humidity. This is not a large overclock, so I was expecting cooler temps from the Noctua.. I can run multiple passes with memtest with no errors. I can run furmark with no artifacts for over an hour. When I play some Bad Company 2, I crash in about 25 minutes. That leads me to believe the PSU is faulty. I did not think this humble system would draw that much wattage. Also, PC Probe reports my Vcore @ 1.45 at idle and it drops to 1.41 at load. CPUZ will show 1.43 at idle and drop to 1.41 at idle. Overdrive always shows 1.41.
In the future I plan to add one more 6850. Should I opt for a 650W or 700-750W? There is about a $30 difference between a 650 and 750 and budget is a huge factor right now. Thanks for your input.
