As we have
discussed in previous nForce4 Intel Edition chipset reviews, is that the memory
bus can be changed independently of the CPU bus simply by entering the speed at
which you wish to run the memory. This degree of flexibility can yield
outstanding results when used in conjunction with CPU front side bus
overclocking. It goes without saying that the combination of CPU and MEMORY bus
speeds is almost limitless. Which is quite a different story on the Intel 925
and 955 chipsets because you're limited to the DRAM ratios preset in the BIOS.
Due to the incredible latency settings these modules are capable of, I will be
putting this dual channel kit to test on both an Intel 955X and nForce4 SLI
Intel Edition Chipset. First, for the nVidia system.

Using SiSoftware Sandra and Science Mark 2.0 as the measurement guide, I
targeted specific clock speeds with the intent of finding the best
possible latency timings which would hold the system stable. The above
chart is the result. Asynchronous CPU / Memory bus speed operation is
not a strong point for the the nForce4 SLI Intel Edition chipset, and
this chart above highlights that all to well. Though the memory was able
to POST, boot, and run stable through benchmarks at the different bus
speeds - the chipset just doesn't gain the memory bandwidth that should
come from higher clock speeds. Still, nVidia does have the only viable
solution for SLI video operation for the Intel Pentium 4.
