We will be testing this memory at 1T timing only, because that is what enthusiasts are using to get maximum performance out of their memory.

Alpha Timing settings in Bios:

We used same Timings as in the G.Skill F1-4000USU2-2GBHZ PC4000 review. Because both memories using the same chips.


At the beginning we tried to determine the best timings for 200 MHz. No matter what voltage we used the result was 2.5-3-3-8, like specified by G.Skill. CAS latency 2 was not possible. I also want to mention that the SPD timings were set incorrect to 3-3-3-8.

The next step was overclocking the memory with stock timings. At 2.6V we could reach 246 MHz and with 2.8V 250 MHz. With more juice it was not possible to get more MHz.

So we lowered timings to 3-3-3-8. At 2.6V the result was the same as with 2.5-3-3-8, 246 MHz. But with 2.8V we could get 6 MHz more (256 MHz)

Now we changed to 3-4-4-8 and got 262 MHz with 2.6V and 272 MHz with 2.8V. That's a 36% overclock. Only 3 MHz less than the big brother G.Skill 4000HZ which is more expensive.

We also tried higher voltage on all timings, but the memory did not benefit from it.
In comparison to the G.SKILL 4000HZ with same chips and same PCB, the 3200HS loves a little bit higher voltage (2.8V), the 4000HZ does not. Maybe the 3200HS have a newer batch of chips.

But do not forget that 2GB always overclocks less than 1GB because of higher density.

The last test "JEDEC DDR-400A" is for comparison with a generic DDR module running at JEDEC standard timings.

SuperPi - 272 MHz; 3-4-4-8; 2.8V


For easier comparison with other modules, we set the maximum voltage required for the best result (here 2.8V; max 3.1V) and tested until we found the highest clock frequency and fastest timings for this memory. The benchmarks Everest Read, Everest Write and Quake 3 were run. We then calculated the performance increase in percent compared to some standard DDR-400 memory running at JEDEC standard timings (2.5-3-3-8). The average percentage of the three benchmarks is listed in following table:
