Taiwanese manufacturer Silicon Power was kind to send to us three 1GB memory modules declared at DDR3-1333 with CL9 latencies. This type of memory can be considered as budget solution so we weren’t surprised with declaration and absence of coolers. Silicon Power used blue coloured PCB and chips signed by ELIXIR. Full specification goes like this: 1333 (667MHz) CL 9-10-10-25, which is by our humble opinion very loosely set timings that leave space for tightening.
Of course, manufacturer certified memory by JEDEC, at standard 1.5V for
DDR3. By our estimation, quality build is in range with Value series of
other manufacturers, which is very nice.
Testing
We performed tests on ASUS Rampage II Extreme motherboard paired with Intel Core i7-920 processor. This combination is capable of achieving memory clock at 1600MHz so we focused on achieving that frequency using timing tightening. We set limit for voltage at maximum of 1.6V for RAM memory because we think that this voltage amount won’t create troubles for any component. First step was testing at 1066MHz with CL8, which is standard frequency for Core i7 platform, and after that we performed tests at 1333MHz. As you can see on graphs, we tested at this frequency with different settings for memory latencies.

First set (CL9) is adjusted to follow SPD of the memory and the second (CL8) is what motherboard gave us after switching on 1333 mode. This is the point where it's obvious that potentials of this memory are definitely higher than manufacturer certified it for. After that we set QPI and memory multiplier so that we can achieve 800MHz (DDR3-1600) for RAM memory and we raised voltage at 1.6V. With this memory voltage at mentioned 1600MHz we succeed to tighten timings more than manufacturer declared on default frequency, which is by our opinion, very good result. You can also see very clearly from graphs how big memory flow rate gains are when memory is overcloked. Also it is important to mention that memory didn’t produce any problems and it perfectly worked with our motherboard. Warming up was small even after we overclocked memory, which only confirms that it doesn’t need additional cooling. All in all, very solid for a budget range memory.
