Benchmarks
Although the
GEIL
G31GB1066C6PXA is rated at DDR3-1066 CAS 6, we should be able to lower the
CAS to achieve higher bandwidth. In this test, we overclock the CPU and see if
it works well beyond the rated 1066.
Firstly, we run the board with a E6300 at 333MHz FSB. That overclocks the CPU and the RAM. The RAM module, using a ASync 4x multiplier now runs at the speed of DDR3-1333. We can see that the RAM actually auto sets itself to run at CAS 8 at a freq of 666MHz (1333MHz) as shown in CPU-Z.
As we can see from the chart, it is rated that at CAS 8, the module is able to go for 711MHz (DDR3-1422MHz). WE overclocked the CPU to achieve that speed by overclocking the CPU to 355MHz FSB. It is quite weird as anything beyond the rated SPD ends up with a reboot. We can't go beyond 355MHz (DDR3-1422) and beyond.
The tests were all done with VDIMM at 1.7v with CPU vcore bumped up by +0.1v from within the BIOS.
Conclusion
The GEIL G31GB1066C6PXA pair (2x 1GB) has performed as to its specification and runs well beyond the 1066 mark. In fact, running at 1333 is well recommended. During our tests, we noticed that lowering the CAS latency wouldn't help much in the performance. Running a board with SYNC clks are still the best to give you a thoughput of 8000+ MB/s. Using ASYnc settings and pushing numbers beyond 1066, 1333, 1500 without the CPU running in SYNC doesn't make good of the bandwidth of the modules.
Nevertheless, the modules are here. If you intend to get higher bandwidth with async settings, this DDR3 module is recommended as we see it has a slight advantage in speed over the others which are rated at a slower speed.
