When it comes to memory testing, PCSTATS has a lot of
experience under our belt to rely on... yet while we've tested a handful of DDR3
memory modules I think we're still a little green on DDR3's full capability.
This will be the first time we're overclocking DDR3 memory modules with tight
timings, so it's uncharted waters for the Mushkin HP3-10666 RAM.
Each 1GB stick of Mushkin HP3-10666 was installed into an
Asus BLITZ Extreme motherboard, along with an Intel Core 2 Duo E6750 processor. Before the
overclocking began, the CPU clock multiplier was set to 6x so the processor
would not limit the memory.
Starting at 333 MHz, the Mushkin HP3-10666 memory speed
was increased in 5 MHz increments. Early on it was clear that these DDR3-1333
modules wouldn't get very far tight 6-7-6-18 timings. The ASUS Blitz Extreme
motherboard had just reached 350 MHz FSB (1400MHz memory speed) when the system
started to show signs of instability, which demanded an increase in memory
voltage to 1.9V.
The Mushkin HP3-10666 memory
didn't overclock any further with its tight timings, and in the end reached a
maximum speed of 363 MHz FSB, or 1452 MHz memory frequency.
Pushing the Mushkin HP3-10666 memory harder, either by
raising the voltage or speed, didn't help.
Let's loosen the memory timings and see how the Mushkin
memory handles overclocking with lax timings.
Starting from the 363 MHz point, with timings loosened to
8-8-8-24, we began overclocking the Mushkin HP3-10666 again.
The Mushkin memory handled the speed increases much
better this time around, reaching a maximum speed of 1760 MHz with 2.0V. It's
not the best overclock we've seen from the small collection of DDR3 memory
PCSTATS has tested thus far, but it's not bad either. The Mushkin HP3-10666 is
for low latency memory users, not those who want really high speeds.
You'll see in the benchmarks shortly what latency does
for performance. Any guesses?
Prelude to Benchmarks

system was configured for benchmarking, including the specific hardware,
software drivers, operating system and benchmark versions are indicated below.

pair of HP3-10666 DDR3 memory is to be compared against. Please take a moment to
