Testing
The test configuration we used is as follows:
| Motherboard: |
Abit IC7-G |
| Processor: |
Intel P4C 2.8Ghz |
| Hard Drive: |
Western Digital ATA 40GB
7200rpm |
| Video Card: |
PNY GF4MX420 AGP |
| Operating System: |
Windows XP Professional SP2 |
| Cooling: |
Air (Alpha PAL8942T) |
Overclocking
For overclocking, we used a 1:1 ratio to
determine the highest stable memory overclock. Hyper-Threading
remained enabled and Game Acceleration was set to AUTO. Memory Timings
were set "By Spd" which reported 3-4-4-7. This is actually lower than its
rated 3-4-4-8.
We were able to take it up to 245FSB, bringing
our CPU clock speed all the way up to 3.41Ghz! Very nice indeed
considering we were running an air cooled setup with no high speed fans running.
Running at this speed was completely stable.
To determine stability, we like to run Sandra's burn-in wizard and cycle
through it 10 times. No issues.
Performance
For the performance tests, we will be running
benchmarks at both stock (200mhz) and maximum OC speeds to give a good
indication of performance gains. We will be using our two preferred
benchmarking suites, Sandra 2004 and PC Mark 2002.
Sandra 2004
Some very high scores as you can see.
There was a substantial increase in memory performance when running at 245FSB.
Very impressive results!
The next test we will run is a new but excellent
benchmark included in the new Sandra 2004 suite. The Cache & Memory
Benchmark is similar to the Memory Bandwidth benchmark. It tests how your CPU
cache and memory sub-system compares to others.
**200FSB**
Results at stock speeds (200FSB) were hand in
hand when compared to the 2.8Ghz reference system.
**245FSB**
Results running at maximum OC where quite
different. Scores were much higher and even surpassed the 3.06Ghz
reference system.
