I have been curious to know the limits you can take a PHENOM II X4 965 BE C2 with an ASETEK 120MM WATERCOOLER via AMD Overdrive. Does anyone have any specifics such as: max stable running temps, steppings, voltage, etc.?

Thanks,

WINDOWS 7 ULITMATE 64x running on: MSI AMD 790FX-GD70; PHENOM II X4 965 BE C2; ASETEK 120MM WATERCOOLER; CORSAIR 2GB 1600MHz X2; ATI HD5870 1GB DDR5; CM 850W REALPOWER PRO all in a COOLERMASTER SCOUT CASE.

As with any over clock, your mileage may vary.  With water cooling i would say 3.8ghz -4ghz with reasonable temps could be within reach.  Every chip, motherboard, and RAM combination will react differently thus there are no specific voltages for speeds.  Depending on how good your IMC is will greatly depend on how much cpu nb vid to give it as well as how much vcore to give the chip.  For 24/7 use try to keep the vcore maxed at 1.5v.  You can obviously go higher for suicide runs, but try to keep it around 1.5v for a 24/7 clock.  The lower the temps the better these things usually over clock so being under water you should be fine.  The max temps for the Phenom II's are 62c, and most people that overclock these chips start to hit walls when their heat hits around 55c at full load.

If you cannot get the clock speed you want, drop it back, and then crank the cpu nb up and try to keep your RAM with as tight of timings as possible.  Get that nb running at 2600mhz and RAM at Cas 6 and you can easily make a 3.6ghz chip run like a 4ghz chip with 2ghz nb and cas 8 RAM.

Thanks for the info and tips... let the tweaking begin! Obviously, if anyone else has any comment, please don't hesitate to throw in your 2 cents... or a couple bucks worth.

Since you were talking about overclocking the memory in another thread, overclock the cpu first then the memory.
