To test the RAM, we ran it in a couple configurations. We ran it at stock speeds and at DDR400 (PC3200) with faster timings (2-3-3-7). The latter was done so that we could test it against the Crucial dual channel RAM we had which operates at DDR400 (3-3-3-7). All tests were performed three times and then the average was taken.

Test System
CPU Intel Pentium 4 2.4C Overclocked to 3.0GHz
Motherboard: ASUS P4C800-E Deluxe
Video ATI Radeon 9800 PRO
RAM 1GB OCZ Gold @ DDR500 Dual Channel - 2.5-4-4-8
1GB OCZ Gold DDR400 Dual Channel - 2-3-3-7
512MB Crucial DDR400 Dual Channel - 3-3-3-7

Lets start off with some synthetic tests. I ran SiSoft Sandra 2004 in buffered and 'unbuffered' modes. This is same technique used in the Crucial PC3200 review I did a short while back, which happens to be the same technique used by AnandTech. Basically, the 'unbuffered' test is the standard memory test with all the special instruction sets and buffering disabled.

The OCZ RAM is the clear winner here. Yes, the timings are better on the OCZ RAM which ways in at twice the size, but the performance margin is rather large.

We see the same story repeated here. If anything, these tests show what you pay for when you buy premium memory.

As you can see, there is only a small gain from the PC4000 speeds over the PC3200 speeds. Also, you can see is that the OCZ memory is much quicker than the Crucial memory.

The Super PI tests, which are floating point calculations (calculates PI to 2 million decimal places), show the same trend as the Quake 3 Arena tests. Floating point calculations are heavy in scientific software. As you can see, having good memory can significantly speed up processing time. For instance, if a meteorologist runs a complete weather model (which can take a day or two to run) this could save him/her whole hours of time.
