This kit consists of two modules each 2GB. For some reason G.Skill states this modules are only for LGA1156 boards. Of course that statement will not hinder us to try them out on our AMD test rig. The specified rating at 1600MHz and 7-8-7-2T timings at 1.35V is impressive. The SPD is detecting the modules with 8-8-8-1T timings, which we recommend to use. If you need it any faster, you can overclock further. G.Skill assured us, the modules will work fine with voltages up to 1.50V.
For normal operation at 1333MHz you need 1.25V to 1.30V. Our AMD board run stable with 1.248V, while the Intel board did need 1.298V. This may be a problem with the BIOS, because most boards do not detect low voltage DDR3 modules correctly, but we hope these glitches will be fixed soon.
Here is what the SPD looks like:
Let's take a look at Everest results, with C-States enabled, running at 1.35V, 1600MHz and 8-8-8-1T.
Not much difference to the Mushkin parts we reviewed recently.
Of course we tested also with AMD, because we think there is no reason why it should not work. Due to a different design the throughput is not comparable to Intel, but the controller can read or write on two channels at any given time.
