SiSoftware Sandra 2003 Memory - Pentium 4 @ 12x200
Although a synthetic benchmark, it's a popular one, freely available if you wish to make comparison benchmarks. We will be testing the memory speeds only. All memory timings are at 2-3-3-5. The Corsair TWINX1024-4000 ProSeries will be indicated as TWINX4000 PS.

Scores are dead even between the two TWINX models, and the OCZ trails the pack by a significant margin. Scores are a little higher than our last PC4000 reviews given that the Game Accelerator is enabled.

All the ram modules scaled accordingly, but this time the ProSeries opens it up a little more. Remember though that the ProSeries is running at 2.5-3-3-6, whereas the other two kits are at 2.5-4-3-6. I wasn't about to handicap the ProSeries if it was capable of running at timings the other kits could not.
SiSoftware Sandra 2003 Memory - Pentium 4 @ Maximum OC (TWINX4000 PS @ 285FSB)

In case you missed it in our last reviews, the original TWINX kit is clicking away at 272FSB, and the OCZ Gold at 280FSB. Considering the ProSeries can handle much higher overclocks, it really flexes its muscles here. Keep in mind that all memory modules are running at 3-4-4-8, 2.9v.
PC Mark 2002 - Pentium 4 @ 12x200

No changes between the two TWINX kits, and as with SiSoft, the OCZ Gold falls quite a bit behind.
PC Mark 2002 - Pentium 4 @ 12x250

Same lead over the OCZ kit, and very close between the two TWINX kits. Despite the improved timings, the gap between the TWINX kits is narrow indeed. We do our benchmarks five times, and the largest gap between the two was no more than 5 PC Marks, with the average being about 2.

The ProSeries continues to dominate, given its 5MHz advantage. Remember though that it's not only the memory that is running at 285FSB, but the CPU as well.
