Performance
Since we have received seven different 4GB memory sticks, the presented performance results will not show the type of results that you can find in matched dual or quad channel kits. However since all memory sticks were based on similar IC (Integrated Circuit) then I have decided to add a short comparison to other, lower clocked memory kits.
The comparison has been made on our ASRock Z87M OC Formula motherboard and Core i5 4670K processor overclocked to 4.2GHz (which is better at showing a performance difference and is easy to set if anyone wishes to compare our results to their own memory).
AIDA64 Cache and Memory benchmark
AVEXIR Blitz 1.1 is performing about the same as the Kingston HyperX Na’Vi Special Edition memory in the AIDA64 tests. It is also faster than the SuperTalent kit which has clearly a poorly optimized SPD.
We can also see that the Intel Haswell platform likes the higher memory clock and the DDR3-1866 memory results are much higher in the AIDA64 tests.
MaxxMem Preview v1.99
MaxxMem Preview is showing memory’s single threading performance. In these tests we can see that all DDR3-1600 kits have similar performance and the DDR3-1866 kit is again noticable faster, especially in the memory copy test.
Cinebench R15
Cinebench is showing us the rendering performance and it is mainly basing on processor power but also shows some differences regarding memory setting changes.
Differences in this benchmark are not big, but are showing slightly the higher performance of the AVEXIR memory which is almost as fast as the DDR3-1866 kit.
Overclocking
Overclocking is never guaranteed so the presented results may vary from results on other memory kits. I am not recommending overclocking if you do not know what are you doing. High voltages may damage hardware and it will not be covered by warranty.
The AVEXIR Blitz 1.1 is memory that is also designed for overclocking. The manufacturer has used top quality parts and PCB to be sure that we received the best memory available.
For overclocking I have also used our ASRock Z87M OC Formula which is one of the best motherboards on the market.
While overclocking the AVEXIR Blitz 1.1 memory I was attempting voltages up to 1.75V. Usually I am trying for higher but in this case I have not seen any changes above ~1.6V. Actually, the optimal voltage for this memory is 1.50V to which I was able to the achieve highest stable memory clock of 1067MHz ( DDR3-2133 ) and respectable 11-11-11-24 1N main timings.
Below are two screenshots showing performance at 1866 CL10 and 2133 CL11 settings. Both are at 1.50V which is the standard voltage for this memory.
DDR3-1866 10-10-10-24 1N 1.50V
2133 11-11-11-24 1N 1.50V
AVEXIR Blitz 1.1 DDR3-1600 overclocking is pretty good but I would like to see it scale higher with voltage. I was not able to set a DDR3-2400 clock regardless of the used voltages or timings. The same tighter timings were not possible. 1600 9-9-9-24, 1866 10-10-10-24 or 2133 11-11-11-24 are optimal settings for this memory.
