X2 4000+ AM2 vs X2 4400+ AM2 Overclock

how far can you overclock a X2 4000 and 4400 AM2 on air? on WC? it will determine if i get the 4000 or 4400.

i have seen some results as high as 2650 for the 4000 and 4800 for the the 4400...are these accurate?

thanks for your results

they are not hard to get

You could possibly (dependent on many factors) hit 2.6-2.9 on either. The 4400 will be easier to hit the higher numbers with. On water cooling you could hit just a tiny bit higher then on air. Assuming your using a good wc vs a good air hsf (also assuming your not doing some kind of ice/slush cooled area for the tank to sit in instead of active cooling).

Water coolers are funny...If you're cooling both a cpu and the nb then your water will be running hotter then it would just on the cpu...Likewise if you're trying to cool a gpu in addition to your cpu. Then you want to look at more tanks, a larger overall one, or preferably a second water system... If you get a crappy internal wc, you'll see the same temps you would see with a avg hsf. External water cooler with active cooling is the way to go if you're trying to keep temps down. There are always a lot of factors to look at...For instance if you're not running air conditioning...yea...that is going to adversely affect your higher oc regardless of water or air (again assuming your tank isn't submerged in slush heh).

Anyway, if you're trying wc, buy a good brand, or put one together yourself (there are a few guides on how to put one together yourself out there:: i'm a fan of using a heater core from an '80s Chevette myself...but i haven't tried it myself). Additionally, if you decide to go with some type of wc...do not test it out for the first time on your hardware...test it outside to make sure it doesn't leak.

Getting an X2 to hit 2.8GHz means you have fortune following you... 2.6GHz is a more reasonable expectation for stable operation.

My water cooled Opteron 175 has problems over 2.75GHz, but runs 2.64GHz fine.

I have an X2 4000+ maxed out stable at 2.85GH with enhanced air cooling (Zalman 9500). Use the speed primarily for gaming and video processing.
With the low cost of these CPU's it's worth the risk to get every Mhz possible.

Someone of SpeedTime OC team had made his X2 4000+ work at 3.67GHZ with WC.

Brisbane 4000+ default 1.25/1.35V (forgot which), DDR2 800 @ 667mhz (with overclocking = 808mhz). 2.8ghz at about 50c.

edit: opps forgot: ARCTIC COOLING Freezer 64 Pro 92mm air cooled.

X2 here, very easy to get to 2.62GHz, 250HTT, HTT>CPU 4x Memory at default+CPU OC=875MHz. More than that gets unstable. Default voltage (1.248v), default multi(10.5) & stock cooling.
