Hello ^_^ need a CPU 775 socket preferably the fastest one for gaming paired with a decent graphics card. My motherboard is a GIGABYTE Ga-945gzm s2 (rev 3.9) chipset is 945gz, 2gb ddr2 slots (I have 800mhxlz Corsair xms2 it posts runs but limits my ram to 667mhz even though it should be 533?) , fsb 1066 max with overclock and latest bios, and 3 pcie slots for a graphics card,450w psu. GIGABYTE says best CPU officially supported is X6800, anyone try with unofically supported ones looking for best possible CPU for this budget build ,,, tried with my modified Xeon x5450 black screen didn't post so maybe they don't work with this chipset.any suggestions yo?
