AMD Phenom II x4 955 BE Overclock (noob)

[dielbe]

So I just built a new system with the 955 and the ASUS Crosshair IV Forumla Mobo. I got the bus up to 237MHz with a 18 times multiplier running at 4.3GHz. This was maxing out at 56C running Prime 95. I decided to back the overclock of reducing the bus to 227 to give me a 4GHz overclock. Thing is... its only running two degrees cooler now! Is it worth/safe to just ramp it up to 4.3GHz again? Running at 1.45 Volts, although it's reading 1.464v in CPU-Z.

Thanks guys!

Why do I always post things in the wrong forums?! I'm such an idiot. Sorry!!

When it comes to temperatures, the voltage is as important if not more important than the actual overclock. When you reduced the bus speeds did you also drop down the voltage? Also CPUZ and BIOs aren't perfectly accurate. If you want to find out the actual voltage you should probably use the voltage probes that come with the Crosshair and use a multimeter.

Also have you benched the performance of the CPU at those speeds, see if the gains are actually noticeable.

if you didnt need to change the voltages to get from 4.0 to 4.3 and the difference was only two degrees, then I personally would keep it at 4.3

As long as your temps dont get dangerously high, then there is no point worrying about a two degrees.

i have mine running running at @4.0Ghz with 240*17 and max temps are 55c @1.44v prime stable too

So I'm now running it at 4.4GHz stable at 200MHz with a 24 multi. Temps max out at 56C after 2 hours of prime.

looking good

How long did those temperatures last for? Coz they like to sneakily go up when you're not looking, so i'd say you need at least 24h hours usage before you can rely on it staying a certain temp. Don't wanna push to the max, leave rig on, go to get some lunch or whatever then come back and find a pile of slag on your desk

2 hours, will run it over night tonight though

whats the voltage dude??

1.45 in BIOS I believe
