Overclocking ‘Skeletor’ Q9450 – Round 2

(see round 1 notes for full specs) After watching a quick youtube of a guy that hit 3.9Ghz (485MHz FSB) where he didn’t bat and eye about leaving his DDR2 at something around 1000MHz, I decided to copy his lead and give up on the 1:1 DRAM:FSB thing and just go for the CPU gusto… I wasn’t seeing much love at 485… it would somehow boot if I goosed the DRAM to 1349 or something like that… but Win7 would reset after boot logo… lower DRAM frequencies wouldn’t even boot until I set it to auto and it came back with 971 🙁 I’m at 420 FSB with 1400 DRAM now and holding in Win7 for a nice stretch here… that’s around 3.4GHz which is at respectable 26% increase… we shall see. Primary OC BIOS settings (gleaned from here)

  • CPU Ratio = 8
  • C1E = disabled (I have no idea)
  • Max CPUID = disabled (ditto)
  • FSB = 420
  • FSB Strap = Auto
  • PCIE Freq = 100
  • DRAM freq = 1400’ish
  • CPU Voltage = 1.39375 (he read that was the safe max somewhere)
  • DRAM Voltage = 1.8 … haven’t played with this at all yet to see if lower would suffice
