Benchmarking 1800MHz:

Even though we set the BIOS to operate at 1800MHz, we had to choose between 1777.8MHz and 1828.6MHz. Since we aren't focusing on overclocking for our main testing, we'll go with the 1777.8MHz (though it was stable at 1828.6MHz too).

CPU-Z Memory @ 1800MHz

We see from the image on the left that the RAM is running at 889.1MHz, so 889.1 x 2 = 1778.2MHz. We also see that our timings are 9-12-12-32. This does not correspond to our 7-7-7-21 as seen a few pages back, and would certainly not achieve these numbers since 1600MHz only did 8-8-8-21.

Memtach v0.93 Alpha:

The Memtach benchmark took 28.12 seconds to run at 1777.8MHz. This is compared to the same test at 1375MHz, which took 27.55 seconds. As you can see from the picture above, the following results were extracted:

I was quite confused by these results. Faster frequencies should produce higher benchmark numbers, and they dropped quite drastically during the 1777.8MHz test, even lower than the 1375MHz frequency.

Performance Test 6.1:

Performance Test 6.1 shows us that the Super Talent DDR3-1800 RAM running at 1777.8MHz gives us 585.3 operations per second, the Memory Mark result shows an average of 653.4, and a PassMark rating of 117.6. We saw earlier that the DDR3-1800 RAM running at 1600MHz gives us 827.9 operations per second, the Memory Mark result shows an average of 667.7, and a PassMark rating of 120.2. This again was a surprise as it showed the RAM running at 1777.8MHz had lower scores than 1600MHz.

RightMark Multi-Threaded Memory Test:

The RightMark test was run on the RAM at 1777.8MHz giving us 4 minutes, 2 seconds - exactly the same as at 1600MHz.

Cache and Memory	Memory Bandwidth	Memory Latency

During the Cache and Memory test, the Super Talent DDR3-1800 kit registered 34.573 GB/sec. This did not rank well with our SiSoft test, as it is essentially based on the RAM timings against DDR2 RAM with lower timings. The previous test at 1600MHz ranked 36.151 GB/sec.

The same rule applies to the Memory Bandwidth test. The tighter the RAM timings, the better the results. Our tests show the memory bandwidth for the DDR3-1800 RAM at 1777.8MHz were 4942MB/sec for Int buffered iSSE2, and 4937MB/sec for Float buffered iSSE2. This compares to 1600MHz showing 5924MB/sec for Int buffered iSSE2, and 5913MB/sec for Float buffered iSSE2.

Finally, our Memory Latency test for 1777.8MHz shows 77ns, ranking #1 against the other Processor/Chipset combos. This compares to 75ns for 1600MHz.
