|Overclocking Results: |
The Socket AM2 90nm AMD Athlon64 processors were pretty
good at overclocking and usually when a processor architecture goes through a
die shrink, overclocking potential increases. It'll be interesting to see how
this first batch of 65nm Athlon64 X2 CPUs handle being pushed to the limit.
Before the overclocking tests got underway, the Corsair Twin2X PC2-8500 memory was first set to run at
DDR2-533 MHz mode, this way it will not hold the CPU back. Keeping the 12.5x CPU
clock multiplier, the Asus M2N32-SLI motherboard clock speed was increased slowly
from 200 MHz on up.
Overclocking in 5 MHz increments, the AMD Athlon64 X2
4800+ was slowly pushed to 215 MHz before the system began experiencing any
signs of instability. At that point the processor voltage had to be increased to
1.35V to stabilize the system.
At 225 MHz the Athlon64 X2 4800+ flaked out, this
time the processor voltage was increased to 1.4V. To reach 235 MHz (or 2.94 GHz)
the processor voltage required another tweak to 1.45V in order to keep the
The AMD Athlon64 X2 4800+ maxed at a motherboard clock
speed of 242 MHz (or 3.03 GHz), anything higher and the system was just too
unstable to run benchmarks. Increasing the voltages didn't help and I have a
feeling that heat might be the issue as the CPU temperatures according to the
Asus M2N32SLI-DLX motherboard were in the range of 70 degrees Celsius.
Enthusiasts should note at stock speeds the AMD Athlon64
X2 4800+ processor did not generate a lot of heat, only when overclocked with a
high voltage did heat loads jumped dramatically. Don't put away that
watercooling or phase change system just yet, you'll still need it for AMD's

gaming, productivity, and 64-bit processor benchmarks. There are a wide variety
of gaming and synthetic benchmarks here to illustrate what kind of performance
