Corsair, Kingston, OCZ, Super Talent DDR3 1800MHz Memory KitsSat, Jan 05, 2008 - 12:00 AM
Sandra XII SP1, Super Pi and WinRAR
Sisoft; Sandra XII SP1:
Sisoft Sandra XII SP1 is designed to test the theoretical power of a complete system and individual components. The numbers taken though are, again, purely theoretical and may not represent real world performance. Higher numbers represent better performance in memory bandwidth. The chart was based off averaged results of the buffered and unbuffered bandwidth scores.
Results: On Sandra XII SP1 the Integer and Float bandwidth results averaged out to just shy of 10,000MB/Sec on the Super Talent 1800MHz DDR3 kit. The difference between 1800MHz 7-7-7 and 1800MHz 8-8-8 showed to be about 300MB/Sec. The spread between the fastest and slowest kit was just 423MB/Sec, which is only 4.4% difference in performance. While this is almost significant, it was just shy of the 5% mark that we need to see before we claim significant performance gains. The Corsair and Super Talent kits both operate at 7-7-7, but the Super Talent kit pulled ahead by 101MB/Sec. This is likely to do with the TRC setting and we will talk about this in the conclusion.
Super PI Mod v1.5:
Super PI is a program a lot of enthusiasts use to benchmark overall system performance, as the program is capable of calculating pi up to 33.55 million digits on a timer. Many overclockers and enthusiasts are in a battle to get the lowest 1M Super Pi time possible. The benchmark results below shows Super Pi results to 4 million places.
Results: Super Pi confirmed what was shown in Sandra XII SP1 memory bandwidth testing. Running CL7 timings do help improve performance according to this test.
RARLAB – WinRar v3.71
WinRAR has a multithreaded version of the RAR compression algorithm, which improves the compression speed on computers with several CPU, dual core CPU and processors with hyperthreading technology. Multithreading is enabled by default, but you can disable it in “General” part of “Settings” dialog.
Results: The WinRAR 3.71 benchmarking results graphed out nicely and showed once again that the CL7 kits performed better than the CL8 kits when all were run at 1800MHz. The Super Talent 1800MHz CL7 kit pulled out in the lead again and beat the OCZ Platinum DDR3 1800MHz memory kit by 94KB/Sec, which at 4.8% is nearly a significant difference.
