OCZ PC4800 Platinum Review - PAGE 3William Henning - Monday, September 19th, 2005
For the rest of the tests and charts we will be comparing the stock 9x200 SPD settings to the best stable overclocked tweaked settings we were able to use.
Rightmark also shows the impressive gains, 34.5% between the SPD timings and the overclocked 2.5-4-4-8 8x300 results. The bandwidth increased a bit better than the 33.3% increase in processor clock speed.
Below we see a very respectable 18.3% increase in speed over SPD settings by going to 2.5-4-4-8 8x300; not the linear increase we saw with read results, but good results nevertheless. Here we see that the PC4000 memory that was able to run with tighter timings actually fares better even with 50MHz slower memory bus.
The 2.5-4-4-8 9x300 setting results in a decrease of 21% in memory latency compared to default settings; quite respectable given the effect of the 2.5-4-4-8 2T timing on the 300MHz memory bus speed. Again, the PC4000 memory running at somewhat tighter timings and a slower bus speed wins.
The combined read/write memory bandwith shows an excellent 29.7% increase over stock settings, almost a linear increase with processor speed increase; however again the lower latencies of the PC4000 with tighter timings beat the PC4800 - mind you, only by a fairly insignificant 1.41%
All these figures support what most tweakers know - that latency timings are also very important to getting the best performance out of your system.
