[Zmaj]

hi all, im new to overclocking and would appreciate if u could give me some tips how to oc this config to 4.0ghz. if its possible?

 

my config:

CPU: Intel® Core™2 Quad Processor Q9650 ES stepping A-1 revision E0 Yorkfield (12M Cache, 3.00 GHz, 1333 MHz FSB)

MBO: Gigabyte GA-X48-DS5 LGA 775

RAM: 8GB DDR2 1066MHz: 2x2GB G.Skill F2-8500CL5D-4GBPI-B, 2x2GB Kingston Hyperx - both 5-5-5-15

Cooler: Zalman 9500 LED

Yes, it is possible.

A little bit voltage tweaking & you can easily attain 3.7-3.8GHz.

ok i read a couple of guides and i succeed to run it stable at 425 fsb x 9 (3.8 GHz). prime95 and memtest without errors or crashes. but whenever i try to put higher fsb blue screen shows when running prime95. didn't try if memtest finds any errors. any suggestions?

CPU voltage is maxed by Intel specifications... should i go higher... temps at this voltage at 425x9 fsb at full load (prime95) don't go over 65°C

That might be the threshold of that chip.
