Memory Tests
HEXUS Pifast and ScienceMark 2.0 are the basis of our memory tests. Pifast gives us an overall view of how things are working, since it's sensitive to memory bandwidth and timings, then ScienceMark tells us bandwidth and access latency to confirm things. Let's see if nForce4 Ultra has any legs over K8T800 Pro in tests that don't have much to do with the core logic.HEXUS Pifast
nForce4 Ultra provides the platform for the first sub 50s run with FX-53, that I've seen before using stock settings. The ECS board isn't too far behind, but the nForce4 Ultra result is impressive. ScienceMark 2.0 shows us why it was so fast.
ScienceMark 2.0 - Memory Bandwidth
Just shy of 5700MB/sec from both setups, with nForce4 Ultra giving the CPU the very slight edge, is class-leading performance. The second factor in a good Pifast run that's not CPU frequency related, is access latency.
ScienceMark 2.0 - Access Latency
The actual score was just shy of 43.5ns, so rounding could well have seen that score for nForce4 Ultra sit at 42s. As it stands, less than 45ns is a good result and shows the memory controller is working at 1T with tight timings on the DRAMs. A clean sweep in the memory tests for nForce4 Ultra and things look promising.
