Performance & Overclocking

The first thing done, when testing this memory is simply running it at the rated speed. Starting with 1200 MHz and CL5-5-5-15 and 2.45V, the system booted right away. Note that I had to use 0.05V more than mentioned on the sticker. Winchip actually allows a +/- 0.1V to run this memory at the intended speed. The second step meant pushing the memory, to see how far it would go. Keeping the 2.45V setting and using a little active cooling, we I managed to raise the speed to 1240 MHz, while keeping the same timings. This may not seem much, but considering the bleeding edge of the memory, the small overclocking result was to be expected.

The next step meant dropping the memory to CL4-4-4-8 and trying various speed settings. Starting with the standard 1066 MHz, I was able to run the Winchip memory at 2.25V. This was then raised back to the maximum, while keeping the CL4 rating. The results were quite impressive with 1172 MHz at which it then ran stable on the Asus P5B. This is almost the rated speed, but at tighter timings.

The third step meant tightening the timings to CL3-2-2-4, which is the minimum the mainboard allows. The memory was set to 533 MHz and the voltage lowered as much as possible. The memory really loves and needs a bit more than default, as it only ran stable at 2.25V with these settings. To see how far I was able to take the timings, the voltage was raised back to the 2.45V and the MHz slowly raised to a whooping 640 MHz at CL3-2-2-4. Trying 667 MHz at these settings resulted in a non-booting system.

The timings were then loosened a bit to 3-3-3-4. while the voltage was kept at maximum. The results are 898 MHz at these settings. This is certainly very impressive.
